Personal Log

Our last day on Oregon II together was filled with lots of hugs and new Facebook friends.  I left Pascagoula, MS and arrived back in Naples, FL around midnight.  It was nice to be back in my big bed but I really missed the rocking of the ship to put me to sleep. 

The next morning I was greeted at my classroom door at 7 am by my students who had a lot of questions.  They all had been following along on my blog and have seen a few pictures that were posted.  I made a PowerPoint of pictures from the ship so they could see what my living and working arrangements were like.  The funniest part was when I showed them my sleeping arrangements.  They thought it was great that I was on the top bunk, but surprised at how small the room was and how I didn’t have a TV.  (I think some thought it was more like a hotel room – boy were they wrong.)  The part they were shocked the most was the size of the shower and the toilet area.  I was able to organize my pictures into folders of the same species.  I was then able to show them all of the wonderful pictures that the crew, scientists, volunteers and I had taken during our excursion. 

The following week a reporter from the Naples Daily News and her photographer came to my classroom to interview me about my trip as well as what the students were learning in AICE Marine.  

I was able to bring back with me the one of the 12 foot monofilament line and hook that is attached to the longline.  I was able to explain to them how the lines are attached and the process for leaving the longline in the water for exactly an hour.  We also started a lesson on random sampling.  I discussed how the location for the longline deployment is chosen and why scientist make sure they are randomly chosen. 

My biggest surprise was a package I received from my Uncle Tom a few days after I returned home.  He is a fantastic artist that paints his own Christmas cards every year.  In the package I received he painted the sunset picture I had taken of Oregon II when we were docked in Galveston.  It is now hanging in my classroom.

In December I will be presenting about my experiences with NOAA.  Students, their families, and people from the Naples community will all be welcome to attend.  I will be working with fellow colleagues from other high schools in Naples that also teach marine to spread the word to their students.  My goal is to get as many students who are interested in a marine career to attend the presentation so that going forward I will be able to work with them in a small group setting to help with college preferences and contacts for marine careers. 

I can’t thank NOAA enough for choosing me to participate as the NOAA Teacher at Sea Alumnus.  The experiences I have received and the information I will be able to pass along to my students is priceless!


Science and Technology Log

My students have been able to see and touch some of the items I was able to bring home from Oregon II that I discussed.  I was able to answer so many questions and show them a lot of the pictures I took. We are anxiously awaiting the arrival of a sharp-nosed shark that is being sent to us from the lab in Pascagoula, MS.  For students that are interested I will be conducting a dissection after school to show the anatomy of the shark as well as let them touch and feel the shark. (An additional blog will be posted once the dissection is competed)

Retrieving the Longline

One hour after the last highflyer is entered into the water it is time to retrieve the longline.  The ship pulls alongside the first highflyer and brings it on board.  Two people carry the highflyer to the stern of the ship.  The longline is then re-attached to a large reel so that the mainline can be spooled back onto the ship.  As the line comes back on board one scientist takes the gangion removes the tag and coils it back into the barrel.  The bait condition and/or catch are added into the computer system by a second scientist.  If there is a fish on the hook then it is determined if the fish can be brought on board by hand or if the cradle needs to be lowered into the water to bring up the species. 

Retrieving the high flyer
Retrieving the high flyer on the well deck

Protective eye wear must be worn at all times, but if a shark is being brought up in the cradle we must all also put on hard hats due to the crane being used to move the cradle.   Once a fish is on board two scientists are responsible for weighing and taking three measurements:  pre-caudal, fork, and total length in mm.  Often, a small fin clip is taken for genetics and if it is a shark, depending on the size, a dart or rototag is inserted into the shark either at the base of the dorsal fin or on the fin itself.   The shark tag is recorded and the species is then put back into the ocean.  Once all 100 gangions, weights and highflyers are brought on board it is time to cleanup and properly store the samples.

Personal Log

It has been a busy last few days.  We have caught some really cool species like king snake eels (Ophichthus rex), gulper sharks (Centrophorus granulosus), yellow edge grouper (Hyporthodus flavolimbatus) and golden tile fish (Lopholaatilus chamaeleontiiceps).  There have been thousands of moon jelly fish (Aurelia aurita) the size of dinner plates and larger all around the boat when we are setting and retrieving the longline.  They look so peaceful and gentle just floating along with the current.  When we were by the Florida-Alabama line there were so many oil rigs out in the distant.  It was very interesting learning about them and seeing their lights glowing.  One of them actually had a real fire to burn off the gases.  There were also a couple sharks that swam by in our ship lights last night.  One of the best things we got to witness was a huge leatherback sea turtle (Dermochelys coriacea) that came up for a breath of air about 50 feet from the ship.

Science and Technology Log

My last blog left off with a late night longline going in the water around 9:00pm on 9/23/19.  We were able to successfully tag a great hammerhead, a scalloped hammerhead, and a tiger shark.  We also caught a blacknose shark, three gafftopsail catfish (Bagre marinus), and three red snappers.

Deploying the Longline

Today I’m going to explain to you the five jobs that we rotate through when we are deploying the longline.  When there are about 15-20 minutes before deployment we grab our sunglasses, personal floatation device (pfd) and rubber boats and head to the stern of the ship.  All scientists are responsible for helping to cut and bait all 100 gangions (hooks and line).  The hooks are 15/0mm circle hooks and the gangion length is 3.7m long.  The bait used for this is Atlantic mackerel cut into chunks to fit the hooks.  We are all responsible for cleaning the deck and the table and cutting boards that were used. 

baiting hooks
Kristin cutting bait and Taniya and Ryan baiting the 100 hooks

The first job on the deployment is setting up the laptop computer.  The scientist on computer is responsible for entering information when the high flyer, the three weights (entered after first high flyer, after gangion 50 and before final high flyer), and the 100 baited gangions entered into the water.  This gives the time and the latitude and longitude of each to keep track of for comparison data. 

The second job is the person actually putting the high flyer and buoy in the water.  Once the ship is in position and we receive the ok from the bridge it is released into the water.  The high flyer is 14ft from the weight at the bottom to the flashing light at the top. (see picture) 

high flyer
Kristin and Kathy getting ready to put the first high flyer in the water

The third job is the “slinger”.  The slinger takes each hook, one by one, off of the barrel, lowers the baited hook into the water,  and then holds the end clamp so that the fourth scientist can put a tag number on each one (1-100).  It is then handed to the deckhand who clamps it onto the mainline where it is lowered into the water off the stern. 

numbers on gangion
Placing the numbers on the gangion before being put on the mainline

The final job is the barrel cleaner.  Once all the lines are in the water the barrel cleaner takes a large brush with soap and scrubs down the inside and outside of the barrel.  The barrels are then taken to the well deck to get ready for the haul in.  The last weight and high flyer are put into the water to complete the longline set, which will remain in the water for one hour.  Everyone now helps out cleaning the stern deck and bringing any supplies to the dry lab.  At this time the CTD unit is put in the water (this will be described at a later time).   


Personal Log

Last night was so exciting, catching the three large sharks.  During this station I was responsible for the data so I was able to take a few pictures once I recorded the precaudal, fork, and total length measurements as well as take a very small fin sample and place it in a vial, and record the tagging numbers. 

Shout Out:    Today’s shout out goes to my wonderful 161 students, all my former students, fellow teachers, especially those in my hallway, my guest teachers and all the staff and administration at Palmetto Ridge High School.  I would also like to thank Mr. Bremseth and Michelle Joyce for my letters of recommendations! 

I couldn’t have been able to do this without all of your help and support.  I have sooo much to tell you about when I get back.  Go Bears!!

9/21/19-We left Galveston, TX late in the afternoon once the backup parts arrived.  After a few changes because of boat traffic near us, were able to get to station 1 around 21:00 (9:00 pm).  We baited the 100 hooks with Atlantic Mackerel.   Minutes later the computers were up and running logging information as the high flyer and the 100 hooks on 1 mile of 4mm 1000# test monofilament line were placed in the Gulf of Mexico for 60 minutes.  My job on this station was to enter the information from each hook into the computer when it was released and also when it was brought onboard.   When the hook is brought onboard they would let me know the status:  fish on hook, whole bait, damaged bait, or no bait.  Our first night was a huge success.  We had a total of 28 catches on our one deployed longline.

We caught 1 bull shark (Carcharhinus leucas), 2 tiger sharks (Galeocerdo cuvier), 14 sharp nose sharks (Rhizoprionodon terraenovae), 2 black tip sharks (Carcharhinus limbatus), 7 black nose sharks (Carcharhinus acronotus), and 2 red snappers (Lutjanus campechanus).  There were also 3 shark suckers (remoras) that came along for the ride.

I was lucky to be asked by the Chief Scientist Kristin to tag the large tiger shark that was in the cradle.  It took me about 3 tries but it eventually went in right at the bottom of his dorsal fin.  He was on hook #79 and was 2300mm total length.  What a great way to start our first day of fishing.  After a nice warm, but “rolling” shower I made it to bed around 1:00 am.  The boat was really rocking and I could hear things rolling around in cabinets.  I think I finally fell asleep around 3:00.

9/22- The night shift works from midnight to noon doing exactly what we do during the day.  They were able to complete two stations last night.  They caught some tilefish (Lopholatilus chamaeleonticeps) and a couple sandbar sharks (Carcharhinus plumbeus).  My shift consists of Kristin, Christian, Taniya, and Ryan: we begin our daily shifts at noon and end around midnight.  The ship arrived at our next location right at noon so the night shift had already prepared our baits for us.  We didn’t have a lot on this station but we did get a Gulf smooth hound shark (Mustelus sinusmexicanus), 2 king snake eels (Ophichthus rex), and a red snapper that weighed 7.2 kg (15.87 lbs).  We completed a second station around 4:00 pm where our best catch was a sandbar shark.  Due to the swells, we couldn’t use the crane for the shark basket so Kristin tried to tag her from the starboard side of the ship. 

We were able to complete a third station tonight at 8:45 pm.  My job this time was in charge of data recording.  When a “fish  is on,” the following is written down: hook number, mortality status, genus and species, precaudal measurement, fork measurement, and total length measurement, weight, sex, stage, samples taken, and tag number/comments.  We had total of 13 Mustelus sinusmexicanus; common name Gulf smooth-hound shark.  The females are ovoviviparous, meaning the embryos feed solely on the yolk but still develop inside the mother, before being born.  The sharks caught tonight ranged in length from 765mm to 1291mm.  There were 10 females and 3 male, and all of the males were of mature status.  We took a small tissue sample from all but two of the sharks, which are used for genetic testing.  Three of the larger sharks were tagged with rototags.  (Those are the orange tags you see in the picture of the dorsal fin below).

I spend most of my downtime between stations in the science dry lab.  I have my laptop to work on my blog and there are 5 computers and a TV with Direct TV. We were watching Top Gun as we were waiting for our first station.  I tried to watch the finale of Big Brother Sunday night but it was on just as we had to leave to pull in our longline.  So I still don’t know who won. 🙂 I slept good last night until something started beeping in my room around 4:00 am.  It finally stopped around 6:30.  They went and checked out my desk/safe where the sound was coming from and there was nothing.  Guess I’m hearing things 🙂

While we are waiting to get started with our research survey that collects fisheries-independent data about sharks, I’ll tell you a little about how other NOAA scientists collect information directly from the commercial shark fisheries in the Gulf of Mexico.

Southeast Shark Bottom Longline Observer Program

Southeast Program

The Shark Bottom Longline Observer Program works to gather reliable data on catch, bycatch, and discards in the Shark Bottom Longline Fishery, as well as document interactions with protected species. Administered by the Southeast Fishery Science Center’s Panama City Laboratory, the data collected by observers helps inform management decisions.  NOAA hires one to six observer personnel under contractual agreements to be placed on commercial fishing vessels targeting shark species. Program coordinators maintain data storage and retrieval, quality control, observer support services (training, observer gear, documents, debriefing, data entry), and administrative support. 

Fishery

This shark bottom longline fishery targets large coastal sharks (e.g., blacktip shark) and small coastal sharks (e.g., Atlantic sharpnose). Groupers, snappers, and tilefish are also taken. The shark bottom longline fishery is active on the southeast coast of the United States and throughout the  Gulf of Mexico. Vessels in this fishery average 50 feet long, with longline gear consisting of 5 to 15 miles of mainline and 500 to 1500 hooks being set. Each trip has a catch limit ranging from 3 to 45 large coastal sharks, depending on the time of year and the region (Gulf of Mexico or south Atlantic). Shark directed trips can range from 3-5 days at sea.

In 2007, NOAA Fisheries created a shark research fishery to continue collection of life history data and catch data from sandbar sharks for future stock assessment. This was created as sandbar sharks are protected due to lower population numbers that allowed for some very limited commercial take of the animals and allows for collection of scientific data on life history etc. A limited number of commercial shark vessels are selected annually and may land sandbar sharks, which are otherwise prohibited. Observer coverage is mandatory within this research fishery (compared to coverage level of 4 percent to 6 percent for the regular shark bottom longline fishery).

Well, I guess you were hoping to hear from me sooner than this.  I arrived in Galveston, TX on September 15th.  I boarded NOAA Ship Oregon II and got settled in my room.  The 170 foot ship was tugged into port early due to a broken part.  Today is Wednesday September 18th , and we are still waiting to leave.  Fingers crossed it will be tomorrow morning.  During this time I was able to meet with the crew members and scientists and familiarize myself with the ship.  I was able to walk around Galveston and learn about its history.  We were able to go out to dinner where I have had amazing oysters and a new dish “Snapper Wings” at Katie’s Seafood Restaurant.   It was delicious and so tender. I would definitely recommend it!      

During our time in port we were also hit with Tropical Storm Imelda. We have had lots of rain and flooding in the area.

Personal Log

Before I leave on my “Twice in a Lifetime Experience” I thought I’d let you know a little more about me.

In May of 2010, I participated in the NOAA TAS program.  The hardest part was leaving my 1 ½ year old son Jonah while I was gone for three weeks.  At the time I was teaching science at Key Biscayne K-8 School, which was located on an island off of Miami, Florida.  I wanted to have my students experience something new so I chose to go to Alaska aboard NOAA Ship Oscar Dyson.  The ship left out of Dutch Harbor, Alaska where the Deadliest Catch is filmed.  We spent the days and night doing neuston and bongo tows to study the walleye pollock (imitation crab meat).  I couldn’t have asked for a better experience and crew!  For more information you can look up my blog in the past season 2010.  I applied for the NOAA TAS Alumni position and now I’m happy to say I will be having a “Twice in a Lifetime Experience” with NOAA!  This time I will be on NOAA Ship Oregon II where we will be tagging and monitoring sharks and red snappers in the Gulf of Mexico.

I grew up in Louisville, KY where I spent most of my summers boating and skiing on the Ohio River.  When I was 10 years old my parents, sister and I got scuba certified.   I guess you could say this is when my love for the ocean began!  Our first trip was to Grand Cayman and we experienced things underwater that were even more beautiful than books and videos could ever show.  I have been back numerous times, but when I went back this past June you can obviously see the changes that are occurring in the ocean and the beaches.  I currently volunteer with Rookery Bay Estuarine Reserve and help with turtle patrol, shark tagging, and trawls.  The amount of garbage we collect is getting out of control.  Teaching the importance of this to my students is one of my top priorities. 

I currently teach AICE Marine and Marine Regular at Palmetto Ridge High School in Naples, Florida.  For the past 5 years I have grown the program into a class that is not just “inside” the classroom.  What better way to learn about marine species and water quality than taking care of your own aquarium?  Throughout the school there are 24 aquariums.  The tanks include saltwater, fresh water, and brackish water.  My students are taught how to properly maintain a tank, checking the water quality and salinity, as well as feeding and caring for their organisms.  In addition to the aquariums they have a quarterly enrichment grade that has them getting outside in our environment and learning about the canals, lakes, and ocean that are just miles from us.  We work with Keeping Collier Beautiful to do canal cleanups twice a year and they also visit Rookery Bay and the Conservancy for educational lessons.  Thanks to the science department at Collier County Public Schools we are also given the opportunity to go out into the estuaries.  Rookery Bay and FGCU Vester lab work with us to get the students out on the water to experience the ecology around them.  Even though we are only miles from the Gulf of Mexico some students have never been out on a boat.  This day trip gives them a hands on learning experience where we complete a trawl and water sampling.

As I leave this weekend I know my students will be in good hands and will be following my blog throughout my journey.  The value of what I am going to be sharing with them far outweighs my short time away.  My goal is to show them you are never too old to try something new and hopefully my experience will get more students into a career in marine sciences. 

Shout outs:  First one goes to my son Jonah (11), my parents Bud and Diane for taking care of him while I’m off having the time of my life, my boyfriend Michael who is currently deployed with the Air Force SFS, and his two kids Andrew (17) and Mackenna (10).  Thanks for your support. Love and miss you all!  <(((><

Science Log

Over the course of this research experience, I have realized that I was not entirely prepared to assist on this voyage. While I think I have pulled my weight in terms of manpower and eagerness, I quickly realized that not having a background in the biological sciences limits my capacity to identify species of fish. Not growing up in the Gulf region, I am already limited in my understanding and recognition of fish variety through their common names like shrimp, grouper, and snapper. Countless other varieties exist most of which have no commercial fishing value such as boxfish, sea robin, spadefish, and scorpionfish. Fortunately, the microbiology grad student paired with me during wet lab processing has been patient and the fishery biologists assigned to this research party have been informative showing me the basics to fish identification (or taxonomy).

The wet lab aboard Oregon II is the nexus of the research team’s work. While the aft deck and the computer lab adjacent to the wet lab are important for conducting research and collecting data, the wet lab is where species are sorted, identified, and entered into the computer. The lab has a faint smell of dead fish and briny water. While the lab is kept clean, it is hard to wash the salt off the surfaces of the lab entirely after every research station.

Alongside the buckets and processing equipment are textbooks, quick reference guides, and huge laminated charts of fish species. Most of the reference material has distinctive color photographs of each fish species with its scientific name listed as the caption. The books in this lab are focused on Gulf and Atlantic varieties as these are what are likely to be found during the surveys. Fishery biologists have a wealth of knowledge, and they pride themselves on knowing all the species that come through the lab. However, occasionally a variety comes through the lab they cannot identify. Some species are less common than others. Even the experts get stumped from time to time and have to rely on the books and charts for identification. To get experience in this process, the biologists have given me crustaceans to look up. I struggle to make matches against pictures, but I have gotten better at the process over the weeks.

As I have learned more about the scientific names of each species we have caught, I have also learned that scientists use a two-name system called a Binomial Nomenclature. Scientists name animals and plants using the system that describes the genus and species of the organism (often based on Latin words and meaning. The first word is the genus and the second is the species. Some species have names that align close to the common name such as scorpionfish (Scorpaena brasiliensis). Others seem almost unrelated to their common name such as scrawled cowfish (Acanthostracion quadricornis).

Fortunately for those of us who do not identify fish for a living, technology has provided resources to aid in learning about and identifying species of fish we encounter. The FishVerify app, for example, can identify a species, bring up information on its habitat and edibility, and tell you its size and bag limits in area based on your phone’s Global Positioning System (GPS). The app is trained on over a thousand different species with the beta version of the app focused on 150 species caught in the waters of Florida. On our research cruise, we have encountered over 150 species so far.

Did You Know?

The naming system for plant and animal species was invented by the Swedish botanist Carl Linnaeus in the 1700s. It is based on the science of taxonomy, and uses a hierarchical system called binomial nomenclature. It started out as a naming system for plants but was adapted to animals over time. The Linnaean system has progressed to a system of modern biological classification based on the evolutionary relationships between organisms, both living and extinct.


Personal Log

Nearly two weeks into this experience and the end of my time with NOAA aboard Oregon II, I find that I have settled into a routine. Being assigned to the “dayshift,” I have seen several sunsets over my shoulder as I have helped deploy research equipment or managed the bounty of a recent trawls. I have missed nearly all the sunrises as the sun comes up five hours after I have gone to bed.

However, these two features along the horizon cannot match the view I have in the morning or late at night. After breakfast and a shower midmorning, I like to spend about 30 minutes gazing at the water from one of the upper decks. The clean light low along the water accentuates its blueish-green hue. In my mind, I roll through an old pack of crayons trying to figure out what color the water most closely represents. Then I realize it’s the Green-Blue one. It is not Blue-Green, which is a lighter, brighter color. The first part of the crayon color name is an adjective describing the second color name on the crayon. Green-blue is really blue with a touch of green, while blue-green is really green with some blue pigment in the crayon. Green-Blue in the crayon world is remarkably blue with a hint of green. The water I have admired on this cruise is that color.

The Gulf in the east feels like an exotic place when cruising so far away from shore. While I have been to every Gulf state in the U.S. and visited their beaches, the blue waters off Florida seem like something more foreign than I am accustomed. When I think of beaches and seawater in the U.S., I think of algae and silt mixed with the sand creating water with a brown or greenish hue: sometimes opaque if the tide is rough such as the coast of Texas and sometimes clear like the tidal pools in Southern California. Neither place has blue water, which is okay. Each place in this world is distinct, but to experience an endless sea of blue is exotic to me.

In contrast to vibrant colors of the morning, the late evening is its own special experience. Each night I have been surprised at how few stars I can see. Unfortunately, the tropic storm earlier in the week has produced sparse, lingering clouds and a slight haze. At night the horizon shows little distinction between the water and the sky. The moon has glided in and out of cover. However, the lights atop the ship’s cranes provide a halo around the ship as it cruises across the open water. What nature fails to illuminate, the ship provides. The water under this harsh, unnatural light is dark. It churns with the movement of the boat like thick goo. Yet that goo teems with life. Every so often a crab floats by along the ships current. Flying fish leap from the water and skip along the surface. Glimpses of larger inhabitants dancing on the edge of the ship’s ring: creatures that are much larger than we work up in the wet lab but illusive enough that it can be hard to determine if they are fish or mammal. (I am hopeful they are pods of dolphins and not a frenzy of sharks).

Science Log

In my previous blog, I mentioned the challenges of doing survey work on the eastern side of the Gulf near Florida. I also mentioned the use of a probe to scan the sea floor in advance of trawling for fish samples. That probe is called the EdgeTech 4125 Side Scan Sonar. Since it plays a major role in the scientific research we have completed, I wanted to focus on it a bit more in this blog. Using a scanner such as this for a groundfish survey in the Gulf by NOAA is not typical. This system was added as a precaution in advance of trawling due to the uneven nature of the Gulf floor off the Florida Coast, which is not as much of a problem the further west one goes in the Gulf. Scanners such as these have been useful on other NOAA and marine conservation research cruises especially working to map and assess reefs in the Gulf.

Having seen the side scanner used at a dozen different research stations on this cruise, I wanted to learn more about capabilities of this scientific instrument. From the manufacturer’s information, I have learned that it was designed for search and recovery and shallow water surveys. The side scanner provides higher resolution imagery. While the imagining sent to our computer monitors have been mostly sand and rock, one researcher in our crew said he has seen tanks, washing machines, and other junk clearly on the monitors during other research cruises.

This means that the side scanner provides fast survey results, but the accuracy of the results becomes the challenge. While EdgeTech praises the accuracy of its own technology, we have learned that accurate readings of data on the monitor can be more taxing. Certainly, the side scanner is great for defining large items or structures on the sea floor, but in areas where the contour of the floor is more subtle, picking out distinctions on the monitor can be harder to discern. On some scans, we have found the surface of the sea floor to be generally sandy and suitable for trawling, but then on another scan with similar data results, chunks of coral and rock have impeded our trawls and damaged the net.

Did You Know?

In 1906, American naval architect Lewis Nixon invented the first sonar-like listening device to detect icebergs. During World War I, a need to detect submarines increased interest in sonar. French physicist Paul Langévin constructed the first sonar set to detect submarines in 1915. Today, sonar has evolved into more sophisticated forms of digital imaging multibeam technology and side scan sonar (see https://oceanexplorer.noaa.gov/explorations/lewis_clark01/background/seafloormapping/seafloormapping.html for more information).


Personal Log

When I first arrived aboard Oregon II, the new environment was striking. I have never spent a significant amount of time on a trawling vessel or a research ship. Looking around, I took many pictures of the various features with an eye on the architectural elements of the ship. One of the most common fixtures throughout the vessel are posted signs. Lamented signs and stickers can be found all over the ship. At first, I was amused at the volume and redundancy, but then I realized that this ship is a communal space. Throughout the year, various individuals work and dwell on this vessel. The signs serve to direct and try to create consistency in the overall operation of the ship and the experience people have aboard it. Some call the ship “home” for extended periods of time such as most of the operational crew. Others, mostly those who are part of the science party, use the vessel for weeks at a time intermittently. Before I was allowed join the science party, I was required to complete an orientation. That orientation aligns with policies of NOAA and the expectation aboard Oregon II of its crew. From the training, I primarily learned that the most important policy is safety, which interestingly is emblazoned on the front of the ship just below the bridge.

Safety First!
Safety First!

The signs seem to be reflective of past experiences on the ship. Signs are not only reminders of important policies and protocols, but also remembrances of challenges confronted during past cruises. Like the additional equipment that has been added to Oregon II since its commission in 1967, the added signs illustrate the history the vessel has endured through hundreds of excursions.

Examples of that history is latent in the location and wording of signs. Posted across from me in the computer lab are three instructional signs: “Do not mark or alter hard hats,” “Keep clear of sightglass do not secure gear to sightglass” (a sightglass is an oil gauge), and “(Notice) scientist are to clear freezers out after every survey.”

Author and journalist Daniel Pink talks about the importance of signs in our daily lives. His most recent work has focused on the emotional intelligence associated with signs. Emotional intelligence refers to the way we handle interpersonal relationships judiciously and empathetically. He is all about the way signs are crafted and displayed, but signs should also be thought of in relation to how informative and symbolic they can be within the environment we exist. While the information is usually direct, the symbolism comes from the way we interpret the overall context of the signs in relation to or role they play in that environment.

Science Log

NOAA Ship Oregon II includes many departments and sections of the ship. As part of the TAS program (Teacher at Sea), I spend most of my time assisting the research team in the wet lab, which occurs in 12-hour shifts. The wet lab is where each catch is brought after it is hauled aboard. The process involves bringing what we find in the trawling net on deck so that we can weigh, sort, count, and measure a subsample of what is found. Fortunately, we do not have to weigh and determine the sex of everything that comes aboard in the net; otherwise, it would take hours when the catch is large. By taking a subsample, fishery biologists can split the catch into percentages depending on the weight of the entire catch and sample size. This subsample’s diversity can then be used as a basis for the entire catch. This conserves our efforts and while still providing an accurate representation of what was caught.

In order to ensure that our leg of the groundfish survey covers the maximum area possible, NOAA uses a method called independent random sampling. A computer program randomly selects stations or research sites based on depth data and spatial area. By choosing random samples independently, fishery biologists can ensure that they have not inadvertently singled out or favored one area over another and that the data collected represents an accurate picture of the fish population in the Gulf. Previous legs of the groundfish survey this summer have focused on research stations along the Texas and Louisiana Gulf coast. Our sampling takes place along the Florida side of the Gulf. The goal is to hit 45-50 research sites during our trip.

So far, I have learned that the eastern side of Gulf can be more challenging to survey than the west. NOAA and its SEAMAP partners have covered less area in the eastern part of the Gulf. While the eastern Gulf is not exactly uncharted waters, NOAA is still perfecting its research techniques in this part of the Gulf. As early as the 1970s, NOAA has surveyed the muddy bottom of the western Gulf off the coast of Texas. In that part of the Gulf, silt from rivers (mostly the Mississippi) makes for a more uniform surface to trawl for fish samples. East of Mobile, Alabama, tends to be rocky and sandy with outcrops of coral and sponge. The craggy surface, while ideal for a host of aquatic species, can create challenges for collecting samples. With each research station we visit on our cruise, we have to be careful not to cause too much damage to the sea floor. Therefore, we have been using a torpedo-shaped probe to scan our trawling paths before we drop the net. While this doubles the time it takes to complete each research station, it does improve our odds of collecting good samples as well as protecting our trawling net from jagged objects that might tear the net.


Did You Know?

A fishery biologist is a scientist who studies fish and their habitats. As biologists, they mostly focus on the behavior of fish in their natural surroundings. Some biologists work mostly in a lab or sorting data in a research facility like NOAA’s office in Pascagoula, but many spend quite a bit of time collecting field samples in various ecological settings. To become a fishery biologist, scientists have to study botany, zoology, fishery management, and wildlife management as a prerequisite to a career in the fish and game biology field. A bachelor’s degree may be acceptable for managerial positions, but many fishery biologists have advanced degrees such as a Master’s or Doctorate.


Personal Log

At the beginning of the cruise, we conducted safety drills aboard Oregon II. Safety drills include fire, man overboard, and abandon ship. Each drill requires the crew to go to various parts of the ship. For fire, the research crew (including myself) heads to the stern (or back of the ship) to wait instructions and to be out of the way of the deck crew working the fire. For man overboard, we are instructed to keep eyes on the individual in the water, yelling for help, and throw life preservers in the water to help mark the person’s location. For abandon ship, the crew meets on the fore deck with their life jackets and “gumby” survival suits (see picture). If life rafts can be deployed, we put on our life jackets and all of us file into groups. If we have to jump into the water, we are asked to put on our red survival suits, which are a cross between a wetsuit and a personal inflatable raft.

I asked Acting Commanding Officer Andrew Ostapenko (normally the Executive Officer but is the acting “captain” of our cruise) about what we would do in the event of a storm. With a length of 170 feet and a width of 34 feet, Oregon II is large enough to handle normal summer squalls and moderate weather like the ones we have sailed through the first few days our trip, but it is important to avoid tropical storms or hurricanes (like Barry, which is gathering near the coast of Louisiana), which are just too big to contend. On the ship, the officers keep a constant watch on the weather forecast with real-time data feeds from the National Weather Service (NWS).

As part of my orientation to the ship, I took a tour of the safety features of Oregon II with the officer in charge of safety for our cruise, OPS Officer LT Ryan Belcher. He showed us what would happen in case of an emergency. There are 6 life rafts on board, and each can hold 16 people. Three rafts position on each side of the ship, and they automatically float free and inflate if that side of the ship goes underwater. An orange rescue boat can be deployed if someone falls overboard, but that craft is more It is more regularly used for man overboard drills and to support periodic dives for underwater hull inspections and maintenance.

If an emergency on the ship did occur, it would be essential to send out a call for help. First, they would try the radio, but if radio communication no longer worked, we also have a satellite phone, EPIRBS (satellite beacons), and a radar reflector (that lets ships nearby know there is an emergency). On the lower tech end, old fashion emergency flares and parachute signals can be launched into the air so other ships could locate us.

Science Log

As I mentioned in my introductory post, the purpose of the SEAMAP Summer Groundfish Survey is to collect data for managing commercial fisheries in the Gulf of Mexico. However, the science involved is much more complex than counting and measuring fish varieties.

The research crew gathers data in three ways. The first way involves trawling for fish. The bulk of the work on-board focuses on trawling or dragging a 42-foot net along the bottom of the Gulf floor for 30 minutes. Then cranes haul the net and its catch, and the research team and other personnel weigh the catch. The shift team sorts the haul which involves pulling out all of the shrimp and red snapper, which are the most commercially important species, and taking random samples of the rest. Then the team counts each species in the sample and record weights and measurements in a database called FSCS (Fisheries Scientific Computer System).

Trawling nets

SEAMAP can be used by various government, educational, and private entities. For example, in the Gulf data is used to protect the shrimp and red snapper populations. For several years, Gulf states have been closing the shrimp fishery and putting limits on the snapper catches seasonally to allow the population to reproduce and grow. The SEAMAP data helps determine the length of the season and size limits for each species.

Tampa Bay area waters

Another method of data collection is conductivity, temperature, and depth measurements (CTD). The process involves taking readings on the surface, the bottom of Gulf floor, and at least two other points between in order to create a CTD profile of the water sampled at each trawling locations. The data becomes important in order to assess the extent of hypoxia or “dead zones” in the Gulf (see how compounded data is used to build maps of hypoxic areas of the Gulf: https://www.noaa.gov/media-release/noaa-forecasts-very-large-dead-zone-for-gulf-of-mexico). Plotting and measuring characteristics of hypoxia have become a major part of fishery research especially in the Gulf, which has the second largest area of seasonal hypoxia in the world around the Mississippi Delta area. SEAMAP data collected since the early 1980s show that the zone of hypoxia in the Gulf has been spreading, unfortunately. One recent research sample taken near Corpus Christi, TX indicated that hypoxia was occurring further south than in the past. This summer, during surveys two CTD devices are being used. The first is a large cylinder-shaped machine that travels the depth of the water for its readings. It provides a single snapshot. The second CTD is called a “Manta,” which is a multi-parameter water quality sonde (or probe). While it can be used for many kinds of water quality tests, NOAA is using it to test for hypoxia across a swath of sea while pulling the trawling net. This help determine the rate of oxygenation at a different depth in the water and across a wider field than the other CTD can provide.

Did You Know?

Algae is a major problem in the Gulf of Mexico. Hypoxia is often associated with the overgrowth of certain species of algae, which can lead to oxygen depletion when they die, sink to the bottom, and decompose. Two major outbreaks of algae contamination have occurred in the past three years. From 2017-2018, red algae, which is common in the Gulf, began washing ashore in Florida. “Red Tide” is the common name for these algae blooms, which are large concentrations of aquatic microorganisms, such as protozoans and unicellular algae. The upwelling of nutrients from the sea floor, often following massive storms, provides for the algae and triggers bloom events. The wave of hurricanes (including Irma and during this period caused the bloom. The second is more recent. Currently, beaches nearest the Mississippi Delta have been closed due to an abundance of green algae. This toxic algae bloom resulted from large amounts of nutrients, pesticides, fertilizers being released into the Bonnet Carre Spillway in Louisiana because of the record-high Mississippi River levels near Lake Pontchartrain. The spillway opening is being blamed for high mortality rates of dolphins, oysters and other aquatic life, as well as the algae blooms plaguing Louisiana and Mississippi waters.

Pulling away from Pascagoula yesterday, I knew we were headed into open waters for the next day and half as we traveled east down the coast to the Tampa Bay, FL area. I stood on the fore deck and watched Oregon II cruise past the shipyard, the old naval station, the refinery, navigation buoys, barrier islands, and returning vessels. The Gulf is a busy place. While the two major oceans that flank either side of the U.S. seem so dominant, the Gulf as the ninth largest body of water in the world and has just as much importance. As a basin linked to the Atlantic Ocean, the tidal ranges in the Gulf are extremely small due to the narrow connection with the ocean. This means that outside of major weather, the Gulf is relatively calm, which is not the case with our trip.

Navigation buoy

As we cruise into open waters, along the horizon we can see drilling platforms jutting out of the Gulf like skyscrapers or resorts lining the distant shore. Oil and gas extraction are huge in this region. Steaming alongside us are oil tankers coming up from the south and cargo ships with towering containers moving back and forth between Latin America and the US Coast. What’s in the Gulf (marine wildlife and natural resources) has geographic importance, but what comes across the Gulf has strategic value too.

The further we cruised away from Mississippi, the water became choppy. The storm clouds that delayed our departure the day before were now overhead. In the distances, rain connected the sky to sea. While the storm is predicted to move northwest, the hope is that we can avoid its intensification over the Gulf Stream as we move southeasterly.

Choppy seas
Choppy seas as we cruise across the Gulf to the West Coast of Florida to start our research.

I learned that water in the Gulf this July is much warmer than normal. As a result, locally produced tropical storms have formed over the Gulf. Typically, tropical storms (the prelude to a hurricane) form over the Atlantic closer to the Equator and move North. Sometimes they can form in isolated areas like the Gulf. Near us, an isolated tropical storm (named Barry) is pushing us toward research stations closer to the coast in order to avoid more turbulent and windy working conditions. While the research we are conducting is important, safety and security aboard the ship comes first.

Science Log

Day one of my trip and we are delayed leaving. Growing up in Oklahoma, you think you know weather until one of the NOAA fishery biologists assigned to the ship provides you a lengthy explanation about the challenges of weather on setting sail. As he put it, the jet stream is throwing off the weather. This is true. Studies have suggested that for a few years the polar jet stream has been fluctuating more than normal as it passes over parts of the Northern Hemisphere. The jet stream is like a river of wind that circles the Northern Hemisphere continuously. That river meanders north and south along the way. When those meanders occur over the Atlantic and the Pacific Oceans, it can alter pressure systems and wind patterns at lower latitudes and that affects how warm or raining it is across North America and Europe. 

This spring in Oklahoma, it has led to record-breaking rains that have flooded low lying areas across the Great Plains and parts of the southeastern United States. Thunderstorms have generally been concentrated in the southern and middle section of the US as the jet stream dips down. The NOAA biologist also indicated that the delay in our departure could be blamed on the El Niño effect. 

El Niño is a natural climate pattern where sea water in the central and eastern tropical Pacific Ocean is warmer than average. This leads to greater precipitation originating from the ocean. According to NOAA scientists, El Niño is calculated by averaging the sea-surface temperature each month, then averaging it with the previous and following months. That number is compared to average temperatures for the same three-month period between 1986 and 2015, called the Oceanic Niño index. When the index hits 0.5 degrees Celsius warmer or more, such as right now, it’s classified as an El Niño. When it’s 0.5 degrees Celsius cooler or more, it’s a La Niña. During an El Niño, the southern part of the U.S. typically experiences wetter than average conditions, while the northern part is less stormy and milder than usual. During a La Niña, it flips, with colder and stormier conditions to the north and warmer, less stormy conditions across the south. However, the El Niño this year has been classified as weak, which means typically the wetter conditions do not push into the Gulf of Mexico region, but exceptions can occur. With the fluctuating jet stream, the El Nino has vacillated between the Plains region and the upper South and regions closer to the Gulf. Thus, the storm causing our delayed departure comes from a weather condition that has been pushed further south by the jet stream.

While these may be causes for the delayed departure, the actual sailing conditions at the time of our voyage are the main concerns. Looking at the NOAA Marine Forecast webpage (https://www.nws.noaa.gov/om/marine/zone/off/offnt4mz.htm), the decision for our delay is based on a storm producing significant wave heights, which are the average height of the highest 1/3 of the waves. Individual waves may be more than twice the average wave heights. In addition, weak high pressure appears to dominate the western Gulf and will likely last mid-week. Fortunately, we are set sail into the eastern Gulf off the coast of Florida. We should be able to sail behind the storm as it moves west. We do have to watch the surface low forming along a trough over the northeast Gulf later in the week. The National Hurricane Center in Miami (which provided weather data in the Atlantic and the Gulf for NOAA) predicts that all of this will intensify through Friday (July 12) as it drifts westward. This will produce strong to near gale force winds and building seas for the north central Gulf. Hopefully by then we will be sailing south of it.

Did You Know?

The weather terms El Niño and La Niña can be translated from Spanish to English as boy and girl, respectively. El Niño originally applied to an annual weak warm ocean current that ran southwards along the coast of Peru and Ecuador around Christmas time before it was linked to a global phenomenon now referred to as El Niño–Southern Oscillation. La Niña is sometimes called El Viejo, anti-El Niño, or simply “a cold event.” El Niño events have been occurring for thousands of years with at least 26 occurring since 1900.

I boarded NOAA’s Oregon II yesterday when the ship was virtually empty. It was Sunday, and we were not set to leave until mid-afternoon the following day (and now Tuesday, July 9). Spending the night on the ship was more comfortable than I had expected. While the stateroom was cramped (I share it with one other crew member), the space is surprisingly efficient. I had plenty of space to store my gear. The bunkbed was more cozy than restricted.

My first look at NOAA Ship Oregon II.

My first day in Pascagoula, MS was spent learning about the town. Pascagoula is a port city with a historic shipyard. Pascagoula is home to the state’s largest employer, Ingalls Shipbuilding, the largest Chevron refinery in the world, and Signal International, an oil platform builder. Prior to World War II, the town was a small fishing community, but the population jumped with war-driven shipbuilding. The city’s population peak in the late 1970s, but today, there are less than 25,000 in the area. Pascagoula continues to be an industrial center surrounded by the growing tourism industry across the Gulf region to the east and west of the port. The population also declined when Naval Station Pascagoula was decommissioned in 2006. The old naval base is located on manmade strip of land called Singing River Island and is in the middle of the port. The port still maintains a large Coast Guard contingent as well as serving as the home portfor the NOAA Ships Gordon GunterOregon II, and Pisces. The NOAA port is actually called the Gulf Marine Support Facility and is located a block from NOAA’s National Marine Fisheries Service Mississippi Laboratory.

Introduction

“There are many good fishermen and some great ones. But there is only one you.”

–Ernest Hemingway (Old Man and the Sea)

As I sit at my home computer, my mind is racing with thoughts of what I need to do before leaving for Mississippi. My family doesn’t quite know what I am doing aboard NOAA Ship Oregon II, not that I am sure either! They vacillate between images of cramped, hot quarters portrayed in old World War II movies like Das Boot (1981), which is about a German submarine crew. In contrast to the sailors traversing icy, choppy waters as in the reality TV show Deadliest Catch, which is about King Crab fishermen in Alaska’s Bering Sea. I am not sure my time aboard Oregon II will be either, but perhaps they will think me braver if I leave that picture in their minds ahead of my trip [wink, wink].

However, before I talk about my trip, I should take a step back and talk about where I came. I am from Oklahoma, one of the most landlocked areas of North America. I grew up in Oklahoma (both Tulsa and Oklahoma City), but have had many other experiences since then. I have been teaching at the collegiate level for 15 years. I mostly instruct high school students taking concurrent enrollment classes and community college students working on undergraduate general education requirements.  I teach regional geography, folklife and traditional culture, and introduction to the humanities at Oklahoma State University—Oklahoma City (OSU-OKC) and Oklahoma City Community College. I am lead faculty in geography at OSU-OKC.

Sarah and Hayden

I earned my BA from Sarah Lawrence College in New York (1994). I studied visual arts, primarily painting and filmmaking, and cultural studies. I earned my MA in Folk Studies from Western Kentucky University, Bowling Green (1998), and I earned my PhD in Geography from the University of Oklahoma, Norman (2015). Through my education and early adult life, I lived coast to coast in seven different states. This education prepared me to work in the field of public history, historic interpretation, community development, and arts administration in addition to teaching at the collegiate level. Before teaching, I worked in Washington, DC for Ralph Nader (yes, the clean water, clean air, clean everything guy…oh, and he ran for president). I worked for several historic sites and cultural agencies, including Mammoth Cave National Park, Kentucky Museum, Historic Carnton, and the Tennessee Arts Commission. I have also worked in education administration. I served as the director the Oklahoma Center for Arts Education for the University of Central Oklahoma, as executive director of the Oklahoma Folklife Council for the Oklahoma Historical Society, and recently, as Director of Community Resources for Western Heights Public Schools. At Western Heights, I have been fortunate to work close to a younger group of students. I have been a part of the expanding arts and science curriculum at the high school. The school district is in the process of renovating the high school science wing and building a new arts and science high school building for an emerging STEAM program. STEAM stands for science, technology, engineering, arts, and math instruction. Working with community partners, I am also involved in promoting college and career readiness at the secondary level.

My research interests include the cultural geography of Oklahoma, family stories and cultural expressions, and community building. However, through my research in folk studies (similar to anthropology) and cultural geography, I have studied human interconnectivity associated with occupations, which is what initially drew my interest to the NOAA Teacher at Sea (TAS) program. In the past, I have studied occupations associated with rural culture and how environment and increased urbanization have effected work settings and their relationship to identity.  My research interest aside, I am excited to learn more about the science of fishery surveys. I think learning about the maritime career opportunities associated with NOAA programs will be important to convey to the students I teach. Especially because so many of my students come from economically challenged, urban settings, and the thought of pursuing a career based on scientific research is foreign. As a geographer, I am also excited to share with students ways they can connect to geography as an influence on their career plans.

Mission Information

I will be part of the third leg of the Southeast Area Monitoring and Assessment Program (SEAMAP) sailing out of the NOAA Pascagoula, MS facility. SEAMAP is a State/Federal/university program for collecting, managing, and disseminating fishery-independent data in the southeastern US. The Gulf of Mexico survey work began in 1981. I have read blogs and videos from NOAA TAS alum that have been part of the similar research cruises, and I have reviewed the NOAA website under the SEAMAP pages and NOAA Oregon II pages. TAS alumni Angela Hung from the 2018 SEAMAP survey crew posted a great blog on roughly what Oregon II crew will be doing while I am sailing (see https://noaateacheratsea.blog/2018/07/03/angela-hung-dont-give-it-a-knife-june-30-2018/). However, I am still working to understand exactly what I will be doing. Coastal culture and scientific research of this nature is new to me. The closest experience I have goes back to my childhood when in the 1980s my mom built a catfish hatchery and commercial pond operation on 10 acres of farmland in southeastern Oklahoma. The “catfish farm” as we called was only in our family for a few years. The next closest experience I have to coastal fisheries is chartering boats for near shore and deep sea fishing adventures on vacation. Clearly, I am in for a lesson on the broader science of understanding and maintaining the ecology of our domestic waterways in the US. This will be an interesting trip, for sure!

Science and Technology Log

 

Participating in the Shark/Red Snapper Longline Survey provided a porthole into several different career paths. Each role on board facilitated and contributed to the scientific research being conducted. Daily longline fishing activities involved working closely with the fishermen on deck. I was in awe of their quick-thinking adaptability, as changing weather conditions or lively sharks sometimes required a minor change in plan or approach. Whether tying intricate knots in the monofilament or displaying their familiarity with the various species we caught, the adept fishermen drew upon their seafaring skill sets, allowing the set and haulback processes to go smoothly and safely.

Even if we were on opposite work shifts, overlapping meal times provided the opportunity to gain insight into some of the careers on board. As we shared meals, many people spoke of their shipboard roles with sentiments that were echoed repeatedly: wanted a career that I could be proud ofa sense of adventureopportunity to see new places and give backcombining adventure and sciencewanted to protect the resources we have

I had the opportunity to speak with some of the engineers and fishermen about their onboard roles and career paths. It was interesting to learn that many career paths were not direct roads, but winding, multilayered journeys. Some joined NOAA shortly after finishing their education, while others joined after serving in other roles. Some had experience with commercial fishing, and some had served on other NOAA vessels. Many are military veterans. With a name fit for a swashbuckling novel set on the high seas, Junior Unlicensed Engineer Jack Standfast, a United States Navy veteran, explained how the various departments on board worked together. These treasured conversations with the Engineering Department and Deck Department were enlightening, a reminder that everyone has a story to tell. I very much appreciate their patience, kindness, and willingness to share their expertise and experiences.

The ship had a small library of books, and several crew members mentioned reading as a favorite way to pass the time at sea. Skilled Fisherman Mike Conway shared several inspiring and philosophical websites that he enjoyed reading.

 

Lead Fisherman and Divemaster Chris Nichols:

In an unfamiliar setting, familiar topics surfaced in conversations, revealing similarities and common interests. Despite working in very different types of jobs, literacy was a popular subject in many of the conversations I had on the ship. I spoke to some of the crew members about how literacy factored into their daily lives and career paths. Some people described their family literacy routines at home and shared their children’s favorite bedtime stories, while others fondly remembered formative stories from their own childhood. Lead Fisherman Chris Nichols recalled the influence that Captains Courageous by Rudyard Kipling had on him as a young reader. He described how exciting stories such as Captains Courageous and The Adventures of Tom Sawyer inspired a sense of adventure and contributed to pursuing a unique career path. Coming from a family of sailors, soldiers, and adventurers, Chris conveyed the sense of pride that stems from being part of “something bigger.” In this case, a career that combines adventure, conservation, and preservation. His experiences with the United States Navy, commercial fishing, NOAA, and scuba diving have taken him around the world.

Echoing the themes of classic literature, Chris recommended some inspiring nonfiction titles and podcasts that feature true stories about human courage, overcoming challenges, and the search for belonging. As a United States Navy veteran, Chris understood the unique reintegration needs that many veterans face once they’ve completed their military service. He explained the need for a “tribe” found within the structure of the military or a ship. Chris described the teamwork on the ship as “pieces of a puzzle” in a “well-oiled machine.”

A pre-dive safety briefing takes place on the ship's bridge.
Led by Divemaster Chris Nichols, also the Oregon II’s Lead Fisherman and MedPIC (Medical Person in Charge), the team gathered on the bridge (the ship’s navigation and command center) to conduct a pre-dive operation safety briefing. Nichols appears in a white t-shirt, near center.

Chris also shared some advice for students. He felt it was easier for students to become good at math and to get better at reading while younger and still in school. Later in life, the need for math may resurface outside of school: “The things you want to do later…you’ll need that math.” As students grow up to pursue interests, activities, and careers, they will most likely need math and literacy to help them reach their goals. Chris stressed that attention to detail—and paying attention to all of the details—is extremely important. Chris explained the importance of remembering the steps in a process and paying attention to the details. He illustrated the importance of knowing what to do and how to do it, whether it is in class, during training, or while learning to dive.

Skilled Fisherman Chuck Godwin:

Before joining NOAA, Skilled Fisherman Chuck Godwin served in the United States Coast Guard for fifteen years (active duty and reserves). After serving in the military, Chuck found himself working in education. While teaching as a substitute teacher, he saw an ad in the newspaper for NOAA careers and applied. Chuck joined NOAA in 2000, and he has served on NOAA Ships Bell M. Shimada, Pisces, Gordon Gunter, and Oregon II.

Echoing Chris Nichols’ description of puzzle pieces in a team, Chuck further explained the hierarchy and structure of the Deck Department on the Oregon II. The Deck Department facilitates the scientific research by deploying and retrieving the longline fishing gear while ensuring a safe working environment. From operating the winches and cranes, to hauling in some of the larger sharks on the shark cradle, the fishermen perform a variety of tasks that require both physical and mental dexterity. Chuck explained that in the event of an unusual situation, the Deck Department leader may work with the Bridge Officer and the Science watch leader and step in as safety dictates.

In addition to his ability to make a fantastic pot of coffee, Chuck has an impish sense of humor that made our twelve-hour work shifts even more interesting and entertaining. Over a late-night cup of coffee, I found out that we shared some similar interests. Chuck attended the University of Florida, where he obtained his bachelor’s degree in Wildlife Management and Ecology. He has an interest in writing and history, particularly military history. He co-authored a published paper on white-tailed deer. An avid reader, Chuck usually completes two or three books during a research cruise leg. He reads a wide range of genres, including sci-fi, westerns, biographies, military history, scientific texts, and gothic horror. Some of his favorite authors include R.A. Salvatore, Ernest Hemingway, and Charles Darwin. In his free time, he enjoys roleplaying games that encourage storytelling and creativity. For Chuck, these adventures are not about the end result, but the plotlines and how the players get there. Like me, Chuck has done volunteer work with veterans. He also values giving back and educating others about the importance of science and the environment, particularly water and the atmosphere. Chuck’s work with NOAA supports the goal of education and conservation to “preserve what we have.”

 

 

Personal Log

Far from home, these brief conversations with strangers seemed almost familiar as we discussed shared interests, goals, and experiences. As I continue to search for my own tribe and sense of belonging, I will remember these puzzle pieces in my journey.

A high flyer and buoy float on the surface of the water.
A high flyer and buoy mark one end of the longline.

My path to Teacher at Sea was arduous; the result of nearly ten years of sustained effort. The adventure was not solely about the end result, but very much about plotlines, supporting (and supportive) characters, and how I got there: hard work, persistence, grit, and a willingness to fight for the opportunity. Every obstacle and roadblock that I overcame. As a teacher, the longline fishing experience allowed me to be a student once again, learning new skills and complex processes for the first time. Applying that lens to the classroom setting, I am even more aware of the importance of clear instructions, explanations, patience, and encouragement. Now that the school year is underway, I find myself spending more time explaining, modeling, demonstrating, and correcting; much of the same guidance I needed on the ship. If grading myself on my longline fishing prowess, I measured my learning this way:

If I improved a little bit each day by remembering one more thing or forgetting one less thing…

If I had a meaningful exchange with someone on board…

If I learned something new by witnessing natural phenomena or acquired new terminology…

If I encountered an animal I’d never seen in person, then the day was a victory.

And I encountered many creatures I’d never seen before. Several species of sharks: silky, smooth-hound, sandbar, Atlantic sharpnose, blacknose, blacktip, great hammerhead, lemon, tiger, and bull sharks. A variety of other marine life: groupers, red snapper, hake, and blueline tilefish. Pelicans and other seabirds. Sharksuckers, eels, and barracudas.

The diminutive creatures were just as interesting as the larger species we saw. Occasionally, the circle hooks and monofilament would bring up small hitchhikers from the depths. Delicate crinoids and brittle stars. Fragments of coral, scraps of seaweed and sponges, and elegant, intricate shells. One particularly fascinating find: a carrier shell from a marine snail (genus: Xenophora) that cements fragments of shells, rocks, and coral to its own shell. The evenly spaced arrangement of shells seems like a deliberately curated, artistic effort: a tiny calcium carbonate collage or shell sculpture. These tiny hints of what’s down there were just as thrilling as seeing the largest shark because they assured me that there’s so much more to learn about the ocean.

At the base of the spiral-shaped shell, the occupant had cemented other shells at regular intervals.

Like the carrier snail’s shell collection, the small moments and details are what will stay with me:

Daily activities on the ship, and learning more about a field that has captivated my interest for years…

Seeing glimpses of the water column and the seafloor through the GoPro camera attached to the CTD…

Hearing from my aquatic co-author while I was at sea was a surreal role reversal…

Fishing into the middle of the night and watching the ink-black water come alive with squid, jellies, flying fish, dolphins, sailfish, and sharks…

Watching the ever-shifting moon, constellations, clouds, sunsets, and sunrise…

Listening to the unique and almost musical hum of the ship’s machinery and being lulled to sleep by the waves…

And the sharks. The breathtaking, perfectly designed sharks. Seeing and handling creatures that I feel strongly about protecting reinforced my mission to educate, protect, and conserve. The experience reinvigorated my connection to the ocean and reiterated why I choose to reduce, reuse, and recycle. Capturing the experience through the Teacher at Sea blog reinforced my enjoyment of writing, photography, and creative pursuits.

Participating in Teacher at Sea provided a closer view of some of my favorite things: sharks, ships, the sea, and marine science.

In my introductory post, I wrote about formative visits to New England as a young child. Like so many aspects of my first glimpses of the ocean and maritime life, the Gloucester Fisherman’s Memorial statue intrigued me and sparked my young imagination. At that age, I didn’t fully grasp the solemn nature of the tribute, so the somber sculpture and memorial piqued my interest in fishing and seafaring instead. As wild as my imagination was, my preschool self could never imagine that I would someday partake in longline fishing as part of a Shark/Red Snapper Survey. My affinity for marine life and all things maritime remains just as strong today. Other than being on and around the water, docks and shipyards are some of my favorite places to explore. Living, working, and learning alongside fishermen was an honor.

Water and its fascinating inhabitants have a great deal to teach us. The Atlantic and the Gulf of Mexico reminded me of the notion that: “Education is not the filling of a pail, but the lighting of a fire.” Whether misattributed to Plutarch or Yeats or the wisdom of the Internet, the quote conveys the interest, curiosity, and appreciation I hope to spark in others as I continue to share my experience with my students, colleagues, and the wider community.

I am very grateful for the opportunity to participate in Teacher at Sea, and I am also grateful to those who ignited a fire in me along the way. Thank you to those who supported my journey and adventure. I greatly appreciate your encouragement, support, interest, and positive feedback. Thank you for following my adventure!

Did You Know?

Xenophora shells grow in a spiral, and different species tend to collect different items. The purpose of self-decoration is to provide camouflage and protection from predators. The additional items can also strengthen the snail’s shell and provide more surface area to prevent the snail from sinking into the soft substrate.

Recommended Reading

Essentially two books in one, I recommend the fact-filled Under Water, Under Earth written and illustrated by Aleksandra Mizielinska and Daniel Mizielinski. The text was translated from Polish by Antonia Lloyd-Jones.

Cover of Under Earth

One half of the book burrows into the Earth, exploring terrestrial topics such as caves, paleontology, tectonic plates, and mining. Municipal matters such as underground utilities, water, natural gas, sewage, and subways are included. Under Earth is a modern, nonfiction, and vividly illustrated Journey to the Center of the Earth.

Diving deeper, Under Water explores buoyancy, pressure, marine life, ocean exploration, and several other subjects. My favorite pages discuss diving feats while highlighting a history of diving innovations, including early diving suit designs and recent atmospheric diving systems (ADS). While Under Earth covers more practical topics, Under Water elicits pure wonder, much like the depths themselves.

Better suited for older, more independent readers (or enjoyed as a shared text), the engaging illustrations and interesting facts are easily devoured by curious children (and adults!). Fun-fact finders and trivia collectors will enjoy learning more about earth science and oceanography. Information is communicated through labels, cross sections, cutaway diagrams, and sequenced explanations.

My entire teaching career has been spent seeking ways to inspire my students to be happy, caring, thoughtful, and courageous stewards of the earth.  It is so easy for someone to go through their day to day life without thinking about the impact that their actions have on the ocean, and the organisms that inhabit its waters.  For as long as I can remember my inspiration has come from Robert Wyland, a renowned marine artist that focuses on teaching awareness about environmental conservation.  Until I completed my Teacher at Sea experience, I had no idea that Robert Wyland has partnered with NOAA in outreach programs to actively engage in teaching students about the importance of marine life conservation.  I am completely humbled knowing that as a Teacher at Sea Alumni, I have also now partnered with NOAA in creating opportunities for kids to become informed and aware of life beyond the classroom.

The ocean stirs the heart,

inspires the imagination and

brings eternal joy to the soul.

Robert Wyland

I love the ocean!  I love the feeling of ‘not knowing’ when I look out over the water.  There are so many unanswered questions about the systems, processes, and organisms that lie beneath the surface.  I cannot express enough the gratitude that I have towards NOAA for choosing me to embark on an adventure that I will remember and share with others for the rest of my life.  The Teacher at Sea experience has changed me.  I am more patient with my students, and I have this unexplained excitement every day in the classroom.  I have always been an upbeat teacher, but my passion for educating my students about the importance of scientific research has taken over.  When I was aboard NOAA Ship Oregon II, I could feel the desire from the NOAA scientists towards their work.  It is amazing to be able to be a part of a team that gets to explore a territory on earth where most humans will never go.  The ocean will always remain to be a mystery, and scientists will forever be challenged to explore, collect data, and draw conclusions about the existence of life offshore.  Wyland once said, “the world’s finest wilderness lies beneath the waves….”.  Knowing that I have been a part of exploring the ocean’s wilderness with NOAA scientists is something that I will cherish forever.

Each summer my co-teacher, Ashley Henderson, and I host a science camp called Ocean Adventure.  This coming summer (2019) we will be adding a new camp called Shark Camp.  Both camps will provide a unique way to educate the young ‘explorers’ in our community on the biological, chemical, and physical forces of the ocean, as well as human impact. Teacher at Sea has provided me with the opportunity to strengthen my knowledge of the ocean, including SHARKS, and will help us create a more impactful experience for the youngsters that attend the camps.  It is important to me to reach out to the children in my community to develop an early interest in science, and nurture that awareness as the students flow through the different grade levels.

Science and Technology Log

My students sent me off with many shark questions before I left for the Shark/Red Snapper Longline Survey. Much of their curiosity revolved around one of the most fear-inducing features of a shark: their teeth! Students wanted to know:

Why do sharks eat fish?
How and why do sharks have so many teeth?
Why do sharks have different kinds of teeth?
Do sharks eat each other? What hunts sharks, besides other sharks?
And one of my favorite student questions: Why do sharks eat regular people, but not scientists?

Most people think of sharks as stalking, stealthy, steel-grey hunters. With a variety of colors, patterns, fin shapes, and body designs, sharks do not look the same. They do not eat the same things, or even get their food the same way. Instead, they employ a variety of feeding strategies. Some gentle giants, like the whale shark (Rhincodon typus), are filter feeders. They strain tiny plants and animals, as well as small fish, from the water. Others, such as the angel shark (Squatina spp.), rely on their flattened bodies, camouflage, and the lightning-fast element of surprise. Instead of actively pursuing their prey, they wait for food to come to them and ambush their meal. These suction-feeding sharks have tiny, pointed, rearward-facing teeth to trap the prey that has been sucked into the shark’s mouth. This video demonstrates how the angel shark uses clever camouflaging and special adaptations to get a meal:

100 circle hooks baited with mackerel. The baited hooks are placed on the edges of barrels, which are sitting on deck.
All 100 circle hooks were baited with mackerel, but sharks also eat a variety of other fish.

The sharks we caught through longline fishing methods were attracted to the Atlantic mackerel (Scomber scombrus) that we used as bait. Depending on the species of shark and its diet, shark teeth can come in dozens of different shapes and sizes. Instead of just two sets of teeth like we have, a shark has many rows of teeth. Each series is known as a tooth file. As its teeth fall out, the shark will continually grow and replace teeth throughout its lifetime—a “conveyor belt” of new teeth. Some sharks have 5 rows of teeth, while the bull shark (Carcharhinus leucas) may have as many as 50 rows of teeth!

The sandbar shark (Carcharhinus plumbeus) usually has about 14 rows of teeth. They may lose teeth every ten days or so, and most sharks typically lose at least one tooth a week. Why? Their teeth may get stuck in their prey, which can be tough and bony. When you don’t have hands, and need to explore the world with your mouth, it’s easy to lose or break a tooth now and then. Throughout its lifetime, a shark may go through over 30,000 teeth. The shark tooth fairy must be very busy!

Similar to our dining utensils, sharks’ teeth are designed for cutting, spearing, and/or crushing. The tooth shape depends upon the shark’s diet. Sharks’ teeth are not uniform (exactly the same), so the size and shape of the teeth vary, depending on their location in the upper and lower jaws. Some sharks have long, angled, and pointed teeth for piercing and spearing their food. Similar to a fork, this ensures that their slippery meals don’t escape. Other sharks and rays have strong, flattened teeth for crushing the hard shells of their prey. These teeth work like a nutcracker or shellfish-cracking tool. Still others, like the famously fierce-looking teeth of the great white, are triangular and serrated. Like a steak knife, these teeth are used for tearing, sawing, and cutting into their prey.

Beyond their teeth, other body features contribute to a shark’s ability to bite, crush, pursue, or ambush their prey. The powerful muscles that control their jaws and swimming ability, the position of their mouth, and the shape of their caudal (tail) fin all influence how a shark gets its food. Unlike humans, sharks do not chew their food. They swallow their food whole, or use their teeth to rip, shred, crush, and tear their food into smaller chunks that the shark can swallow. No need to floss or brush after a meal: sharks’ teeth contain fluoride, which helps to prevent cavities and decay.

Some people may find it hard to swallow the idea that sharks aren’t mindless menaces, but shark encounters are quite rare. Sharks have many extraordinary adaptations that make them efficient swimmers and hunters of other marine life, not humans. Whenever sharks come up in conversation, I am careful to dispel myths about these captivating creatures, trying to replace fear with facts (and hopefully, curiosity and respect). Since sharks can’t talk, I’m happy to advocate for them. Despite the way sharks are negatively portrayed in the media, I assure my students that sharks far prefer to eat bony fish, smaller sharks, skates, rays, octopus, squid, bivalves, crustaceans, marine mammals, plankton, and other marine life over humans. Instead of fear, I try to instill awareness of the vital role sharks fulfill in the ecosystem. We are a far greater threat to them, and they require our respect and protection.

Personal Log

As storms and hurricanes tear across the Gulf of Mexico, causing destruction and devastation, my thoughts are with the impacted areas. Before my Teacher at Sea placement, I never thought I’d spend time in the region, so it’s interesting to see now-familiar locations on the news and weather maps. One of my favorite aspects of being at sea was watching the sky: recognizing constellations while fishing at night, gazing at glorious, melting sunsets, and observing storm clouds gathering in the distance. The colors and clouds were ever-changing, a reminder of the dynamic power of nature.

Watching the recent storm coverage on TV reinforced the importance of strong and accurate communication skills. Similar to a sidebar on the page, much of the supplementary storm information was printed on the screen. For someone who needed to evacuate quickly or was worried about loved ones in the area, this printed information could be crucial. As I listened to the reporters’ updates on the storm damage, aware that they were most likely reading from scripted notes, I was reminded of the challenge of conveying complex science through everyday language.

One might assume that a typical day at sea only focused on science, technology, and math. In fact, all school subjects surfaced at some point in my experience at sea. For example, an understanding of geography helped me to understand where we were sailing and how our location influenced the type of wildlife we were seeing. People who were more familiar with the Gulf of Mexico shared some facts about the cultural, economic, and historical significance of certain locations, shedding light on our relationship with water.

Fishing is an old practice steeped in tradition, but throughout the ship, modern navigation equipment made it possible to fish more efficiently by plotting our locations while avoiding hazards such as natural formations and other vessels. Feats of engineering provided speed, power, drinkable water, and technological conveniences such as GPS, air conditioning, and Wi-Fi. In contrast to the natural evolution of sharks, these artificial adaptations provided many advantages at sea. To utilize the modern technology, however, literacy was required to input data and interpret the information on the dozens of monitors on board. Literacy and strong communication skills were required to understand and convey data to others. Reading and critical thinking allowed us to interpret maps and data, understand charts and graphs, and access news articles about the red tide we encountered.

I witnessed almost every person on board applying literacy skills throughout their day. Whether they were reading and understanding crucial written communication, reading instructions, selecting a dinner option from the menu, or referencing a field guide, they were applying reading strategies. In the offices and work spaces on board, there was no shortage of instructional manuals, safe operating procedures, informational binders, or wildlife field guides.

Writing helped to organize important tasks and schedules. To manage and organize daily tasks and responsibilities, many people utilized sticky notes and checklists. Computer and typing skills were also important. Some people were inputting data, writing research papers and projects, sharing their work through social media, or simply responding to work-related emails. The dive operation that I observed started as a thoroughly written dive plan. All of these tasks required clear and accurate written communication.

Junior Unlicensed Engineer (JUE) Jack Standfast holds a small notebook used for recording daily tasks and responsibilities.
Junior Unlicensed Engineer (JUE) Jack Standfast carried a small notebook in his pocket, recording the various engineering tasks he’d completed throughout the day.

Each day, I saw real-life examples of the strong ties between science and language arts. Recording accurate scientific data required measurement, weight, and observational skills, but literacy was required to read and interpret the data recording sheets. Neat handwriting and careful letter spacing were important for recording accurate data, reinforcing why we practice these skills in school. To ensure that a species was correctly identified and recorded, spelling could be an important factor. Throughout the experience, writing was essential for taking interview notes and brainstorming blog ideas, as well as following the writing process for my blog posts. If I had any energy left at the end of my day (usually around 2:00 AM), I consulted one of my shark field guides to read more about the intriguing species we saw.

 

Did You Know?

No need for a teething ring: Sharks begin shedding their teeth before they are even born. Shark pups (baby sharks) are born with complete sets of teeth. Sharks aren’t mammals, so they don’t rely upon their mothers for food after they’re born. They swim away and must fend for themselves, so those born-to-bite teeth come in handy.

Smart About Sharks written and illustrated by Owen Davey

Appropriate for older readers, the clever, comprehensive text offers interesting facts, tidbits, and trivia. The book dives a bit deeper to go beyond basic shark facts and knowledge. I’ve read hundreds of shark books, and I appreciated learning something new. The text doesn’t shy away from scientific terminology and concepts, such as phylogeny (eight orders of sharks and representative species). The facts reflect recent research findings on shark behavior. Lesser-known species are included, highlighting the diversity in body shapes, sizes, and specialized features. From a design standpoint, the aesthetically appealing illustrations are stylized, colorful, and engaging. Simple infographics provide explanations of complex ideas. Fact meets fiction in a section about shark mythology from around the world. The book concludes with a discussion of threats to sharks, as well as ocean conservation tips.

Science and Technology Log

Today is our last day at sea and we have currently completed 53 stations!  At each station we send out the CTD.   CTD stands for Conductivity, Temperature and Depth.   However, this device measures much more than that.  During this mission we are looking at 4 parameters: temperature, conductivity, dissolved oxygen and fluorescence which can be used to measure the productivity of an area based on photosynthetic organisms.

Once the CTD is deployed, it is held at the surface for three minutes.  During this time, 4,320 scans are completed!  However, this data, which is used to acclimate the system, is discarded from the information that is collected for this station.

The crane lifts the CTD from the well deck and deploys it into the water.

Next, the CTD is slowly lowered through the water until it is about 1 meter from the bottom.  In about 30 meters of water this round trip takes about 5 minutes during which the CTD conducts 241 scans every 10 seconds for a grand total of approximately 7,230 scans collected at each station.

Data from CTD scans was used to create this map of hypoxic zones off the coast of Louisiana in summer of 2018.

 

Personal Log

The gloomy weather has made the last few days of the voyage tricky. Wind and rough seas have made sleeping and working difficult. Plus, I have missed my morning visits with dolphins at the bow of the ship due to the poor weather.  But seeing the dark blue water and big waves has added to the adventure of the trip.

Dark clouds lifting
The gloom is lifting as a tanker passes in the distance.

We have had some interesting catches including one that weighed over 800 pounds and was mostly jellyfish.  Some of the catches are filled with heavy mud while others a very clean. Some have lots of shells or debris.  I am pleasantly surprised to see that even though I notice the occasional plastic bottle floating by, there has not been much human litter included in our catches.  I am constantly amazed by the diversity in each haul.  There are species that we see at just about every station and there are others that we have only seen once or twice during the whole trip.

I am thrilled to have had the experience of being a NOAA Teacher at Sea and I am excited to bring what I have learned back to the classroom to share with my students.  

 

Challenge Question:

Science and Technology Log

After our delayed departure, we are finally off and running! The science team on Oregon II has currently completed 28 out of the 56 stations that are scheduled for the first leg of this mission. Seventy-five stations were originally planned but due to inclement weather some stations had to be postponed until the 2nd leg. The stations are pre-arranged and randomly selected by a computer system to include a distributions of stations within each shrimp statistical zone and by depth from 5-20 and 21-60 fathoms.

Planned stations and routes
Planned stations and routes

At each station there is an established routine that requires precise teamwork from the NOAA Corps officers, the professional mariners and the scientists. The first step when we arrive at a station, is to launch the CTD. The officers position the ship at the appropriate location. The mariners use the crane and the winch to move the CTD into the water and control the decent and return. The scientists set up the CTD and run the computer that collects and analyzes the data. Once the CTD is safely returned to the well deck, the team proceeds to the next step.

Step two is to launch the trawling net to take a sample of the biodiversity of the station. Again, this is a team effort with everyone working together to ensure success. The trawl net is launched on either the port or starboard side from the aft deck. The net is pulled behind the boat for exactly thirty minutes. When the net returns, the contents are emptied into the wooden pen or into baskets depending on the size of the haul.

red snapper haul
This unusual haul weighed over 900 pounds and contained mostly red snapper. Though the population is improving, scientists do not typically catch so many red snapper in a single tow.

The baskets are weighed and brought into the wet lab. The scientists use smaller baskets to sort the catch by species. A sample of 20 individuals of each species is examined more closely and data about length, weight, and sex is collected.

The information gathered becomes part of a database and is used to monitor the health of the populations of fish in the Gulf. It is used to help make annual decisions for fishing regulations like catch and bag limits. In addition, the data collected from the groundfish survey can drive policy changes if significant issues are identified.

Personal Log

I have been keeping in touch with my students via the Remind App, Twitter, and this Blog. Each class has submitted a question for me to answer. I would like to use the personal log of this blog to do that.

3rd Period - Marine Science II
3rd Period – Marine Science II: What have you learned so far on your expedition that you can bring back to the class and teach us?

The thing I am most excited to bring back to Marine 2 is the story of recovery for the Red Snapper in the Gulf of Mexico. I learned that due to improved fishing methods and growth in commercial fishing of this species, their decline was severe. The groundfish survey that I am working with is one way that data about the population of Red Snapper has been collected. This data has led to the creation of an action plan to help stop the decline and improve the future for this species.

4th Period - Marine Science I
4th Period – Marine Science I: What challenges have you had so far?

Our biggest challenge has been the weather! We left late due to Hurricane Michael and the weather over the past few days has meant that we had to miss a few stations. We are also expecting some bad weather in a couple of days that might mean we are not able to trawl.

5th Period - Marine Science I
5th Period – Marine Science I: How does the NOAA Teacher at Sea program support or help our environment?

The number one way that the NOAA Teacher at Sea program supports our environment is EDUCATION! What I learn here, I will share with my students and hopefully they will pass it on as well. If more people know about the dangers facing our ocean then I think more people will want to see changes to protect the ocean and all marine species.

7th Period - Marine Science I
7th Period – Marine Science I: What is the rarest or most interesting organism you have discovered throughout your exploration?

We have not seen anything that is rare for the Gulf of Mexico but I have seen two fish that I have never seen before, the singlespot frogfish and the Conger Eel. So for me these were really cool sightings.

 

 

 

 

 

 

 

 

 

 

8th Period - Marine Science I
8th Period – Marine Science I: What organism that you have observed is by far the most intriguing?

I have to admit that the most intriguing organism was not anything that came in via the trawl net. Instead it was the Atlantic Spotted Dolphin that greeted me one morning at the bow of the boat. There were a total of 7 and one was a baby about half the size of the others. As the boat moved through the water they jumped and played in the splashing water. I watched them for over a half hour and only stopped because it was time for my shift. I could watch them all day!

Do you know …

What the Oregon II looks like on the inside?
Here is a tour video that I created before we set sail.

 

Transcript: A Tour of NOAA Ship Oregon II.

(0:00) Hi, I’m Andria Keene from Plant High School in Tampa, Florida. And I’d like to take you for a tour aboard Oregon II, my NOAA Teacher at Sea home for the next two weeks.

Oregon II is a 170-foot research vessel that recently celebrated 50 years of service with NOAA. The gold lettering you see here commemorates this honor.

As we cross the gangway, our first stop is the well deck, where we can find equipment including the forecrane and winch used for the CTD and bongo nets. The starboard breezeway leads us along the exterior of the main deck, towards the aft deck.

Much of our scientific trawling operations will begin here. The nets will be unloaded and the organisms will be sorted on the fantail.

(1:00) From there, the baskets will be brought into the wet lab, for deeper investigation. They will be categorized and numerous sets of data will be collected, including size, sex, and stomach contents.

Next up is the dry lab. Additional data will be collected and analyzed here. Take notice of the CTD PC.

There is also a chemistry lab where further tests will be conducted, and it’s located right next to the wet lab.

Across from the ship’s office, you will find the mess hall and galley. The galley is where the stewards prepare meals for a hungry group of 19 crew and 12 scientists. But there are only 12 seats, so eating quickly is serious business.

(2:20) Moving further inside on the main deck, we pass lots of safety equipment and several staterooms. I’m currently thrilled to be staying here, in the Field Party Chief’s stateroom, a single room with a private shower and water closet.

Leaving my room, with can travel down the stairs to the lower level. This area has lots of storage and a large freezer for scientific samples.

There are community showers and additional staterooms, as well as laundry facilities, more bathrooms, and even a small exercise room.

(3:15) If we travel up both sets of stairs, we will arrive on the upper deck. On the starboard side, we can find the scientific data room.

And here, on the port side, is the radio and chart room. Heading to the stern of the upper deck will lead us to the conference room. I’m told that this is a great place for the staff to gather and watch movies.

Traveling back down the hall toward the bow of the ship, we will pass the senior officers’ staterooms, and arrive at the pilot house, also called the bridge.

(4:04) This is the command and control center for the entire ship. Look at all the amazing technology you will find here to help keep the ship safe and ensure the goals of each mission.

Just one last stop on our tour: the house top. From here, we have excellent views of the forecastle, the aft winch, and the crane control room. Also visible are lots of safety features, as well as an amazing array of technology.

Well, that’s it for now! Hope you enjoyed this tour of NOAA Ship Oregon II.

Science/Technology and Personal Log

Hurricane Michael brought a three day delay to our departure. At first, I was a little disappointed that we were not setting sail right away but now I am glad because I had some extra time to explore Pascagoula, familiarize myself with the ship, and slowly meet the crew as they arrived spread out over several days. Plus, the additional time allowed me to start working on my career lesson plan and to prepare a video tour of the ship. I will upload the video to this blog page as soon as it is complete.

On Thursday, Oct 11th at 9:00am, we departed from Pascagoula and headed out into the Gulf of Mexico. I was amazed at how quickly we lost sight of land and at the vastness of this body of water with which I thought I was so familiar. My favorite part was watching the color of the water change from a dark teal to a deep blue.

On the “Plan of the Day” board under schedule it reads “Steam and Dream til Saturday Afternoon” and that is just what we are doing. Our path will lead us north of the Mexican border and south of Corpus Christi, Texas, where we will find our first station. Until then, in between steaming and dreaming, we are getting to know each other and learning about our roles and responsibilities.

 

 

 

 

 

 

Abandon ship drill
Abandon ship drill! Here I am in my survival suit.

For example, today we practiced our Fire and Abandon Ship Drills. While it is a little nerve-racking to think that something like that could actually happen, it was reassuring to see that everyone was well-trained and the operations ran smoothly.

 

 

 

 

 

 

 

 

My first lesson plan will focus on careers available through NOAA. It is amazing to see the variation in the positions and the backgrounds of the workers on this ship. Basically, on the Oregon II there are three types of employees who make up the ship’s complement.

Types of Employees
This graphic illustrates the structure of the employees aboard Oregon II.

I feel like NOAA has something to offer everyone from entry level positions that require no experience to positions requiring years of experience or advanced college degrees. The best part is that no matter where you start there is always room to advance through hard work and certification. I can’t wait to share all the opportunities with my students!

 

Did You Know?

Oregon II has a reverse osmosis system that uses salt water to create the freshwater needed aboard.  The salt that is removed is returned back to the Gulf.

Science and Technology Log

The past three days were light catch days.  One day, we only caught a snake fish, which, as you can see, is a pretty tiny little guy.  But, the data from a catch that brings up nothing is just as important as a catch that brings up 50 fish.  As the saying goes, “If we always caught something, we would call it catching, not fishing.”  We have brought up a few Sandbar sharks and Tiger sharks, some of them large enough to have to cradle.  I have gotten to tag a few of the Sandbar sharks, which is still an amazing experience.

Snakefish

While we did not see many sharks, I had fun seeing the other organisms at the surface.  There have been a lot of moon jellyfish as we have been pulling the line in, and it was clear enough that I was able to get a picture of a few of them as they floated by.  One night, there were flying fish next to the ship, and one of them jumped onto the deck, so I was able to see one up close.  One of the days, a pod of dolphins joined us on a run, and followed the boat for quite a while.  So, while we did not see many sharks, I was able to see some awesome animals throughout the past few days.

The last night on the ship, I finished cleaning my shark jaws.  Overnight, they soaked in hydrogen peroxide to whiten them, and today I set them to dry.  I’m looking forward to taking them home and sharing them with all of my students.

It was an amazing two weeks.  On Friday night, we set our last line, and it was bittersweet.  Over the past two weeks, I have been able to fish with an amazing group of people.  They allowed me to be a part of the team, and attempt each job setting and pulling in the line.  I was able to put out the high flyer, sling bait, place numbers, clean barrels, and keep data on the computer.  I learned how to tie a double-overhand knot, handle small sharks, tag sharks of all sizes, and had lots of fun doing it.  I’m excited to head back to T-STEM Academy at East High School, but I will always fondly remember my time on the Oregon II.

Personal Log

One of the things that the night shift has done a few times is midnight hot dogs.  Chris, the night shift lead fisherman, brings different types of hot dogs on the boat and will cook them at midnight for the shift change.  It gives the night shift members something to eat before breakfast at 7 AM, and gives the day shift something to eat before bed.  They go all out, with a condiment bar and gourmet buns.

 

Did You Know?

Once the Oregon II returns to port from this fourth leg of the Shark/Red Snapper Longline Survey, they will spend a week cleaning and preparing the ship to return to the Gulf of Mexico on a Groundfish Survey that will run from October 8-November 21.  NOAA Groundfish surveys allow for the collection of data on the distribution of flora and fauna within the target region through the use of trawl nets.

 

Quote of the Day

Science and Technology Log

We have moved from the coast of Texas, past Louisiana, Mississippi, and Alabama, to the coast of Florida.  When watching the video from the CTD, we have seen the sea floors go from mostly mud to sand.  The water has decreased in turbidity, and the growth on the sea floor has increased.  The make-up of our catches has changed too.  We moved outside of the productive waters associated with the Mississippi River discharge, so our catch rates have decreased significantly.

Yesterday, we had a fun day of catching sharks I had never seen.  Our first catch of the day brought up a juvenile Tiger shark (Galeocerdo cuvier).  I was excited to be able to see this shark, which is listed as near threatened by the International Union for Conservation of Nature.  On our later catch, we brought up three sharks large enough to require the cradle.  First, we brought up a Sandbar shark (Carcharhinus plumbeus).  Then, we were lucky enough to bring up a Nurse Shark (Ginglymostoma cirratum).  The mouth of the nurse shark has barbles, which it uses to feed from the sea floor.  Our final shark of the evening was a much more developed Tiger Shark.  I was lucky enough to help with the tagging of the animal.

Last night, we set a line at the end of day shift, and night shift brought it in.  A few of the day shift science team members decided to stay up and watch some of the haul back, and were rewarded with seeing them bring in, not one, but two Silky sharks (Carcharhinus falciformis), back to back.  From the upper deck of the ship, so that I was not in their way, I was able to observe the night shift work together to bring up these two large animals.

The night shift has gotten some pretty amazing catches, and they have enjoyed sharing them with us at shift change.  The two shifts spend about half an hour together around noon and midnight sharing stories of the time when the other shift was asleep.  The other day, the night shift caught Gulper Sharks (Centrophorus uyato) and Tile Fish (Lopholatilus chamaeleonticeps).  These are two species we have not seen on the day shift, so it was fun to look at their pictures and hear the stories of how they caught these fish.

Personal Log

When we have a long run between stations, once I have gotten done sending emails and grading student work, we will spend some time watching movies in the lounge.  The ship has a large collection of movies, both classic and recent.  Watching movies keeps us awake during the late night runs, when we have to stay up until midnight to set a line.

The day shift has started to ask one another riddles as we are baiting and setting lines.  It’s a fun way to bond as we are doing our work.  One of my favorites have been: “1=3, 2=3, 3=5, 4=4, 5=4, 6=3, 7=5, 8=5, 9=4, 10=3.  What’s the code?”

Did You Know?

Sharks don’t have the same type of skin that we do.  Sharks have dermal denticles, which are tiny scales, similar to teeth, which are covered with enamel.

Scientific Journal: 

While aboard the NOAA Ship Oregon II, I was able to create some art, which is my absolute passion in life. I was able use my time before and after most shifts to draw and paint the fish and sharks with watercolor paint and water from the ocean. It was tricky to paint with the constant movement of the ship, but I was able to paint over 20 paintings of sharks, fish, and the Oregon II over the 16 days on board the ship.

Now that I’ve been home for a month, I’ve had some time to reflect on my NOAA Teacher at Sea experience. If I told you my NOAA Teacher At Sea experience was incredible, I would be understating it quite a bit. I knew the excitement of working on the mighty NOAA Ship Oregon II and participating in the shark survey would be a highlight of my lifetime for sure. The opportunity to work with NOAA scientists, fishermen, and the rest of the crew was the best learning experience a teacher and artist could ask for. But just a week after returning, it was back to school and I needed to find ways to convey what I learned to my students. I began by creating a digital infographic about Longline Fishing so they would have a visual to go along with my explanation.

I wanted to inform my students to create awareness about the species of shark and other ocean inhabitants that are threatened and endangered. I also wanted them to learn science about the animals and incorporate some of that data into their art to make their images more impactful to those that see them. We want to compile related projects together until later in the year for our annual Night of the Arts- NOAA Edition.

We also created three life size Art Shark paintings and posted them in the hallways of our school to advocate for sharks through art and work to give sharks a more positive community image, and not the sensational, fearful media portrayal of sharks.

As a fine artist painter, the Teacher At Sea experience has helped to make my artwork much more accurate for several reasons. Primarily the reason was proximity. I was able to see the sharks and fish first hand everyday, and take many reference photos of our catch each day. I could now see the beautiful colors of different sharks while out of the water, which I never had seen before. I was also able to speak to the fishermen and scientists each day about the behaviors and biology of the fish and I gained insight from listening to their vast experiences in the oceans all around the globe.

Since being home, I’ve begun to paint a series of scientifically accurate side views of my favorite sharks, and eventually I will digitally compile them into one poster after I get 15 to 18 completed. After that, I’ll begin a series of paintings with sharks swimming in their natural environment to bring more color and visual dynamics onto the canvas. This has been the most inspiring adventure of my life, and I will continue to advocate for my favorite ocean animals by using art to bring the respect and admiration that these beautiful sharks deserve to continue to thrive long into Earth’s distant future.

Science and Technology Log

The idea of placing an elementary school teacher on a Shark/Red Snapper Longline Survey seems like a reality show premise, and I couldn’t believe that it was my surreal reality. Several times a day, I took a moment to appreciate my surroundings and the amazing opportunity to get so close to my favorite creatures: sharks!

Anyone who knows me is aware of my obsession with sharks. Seeing several sharks up close was a hallowed, reverential experience. Reading about sharks, studying them through coursework, and seeing them on TV or in an aquarium is one thing. Being only a few feet away from a large tiger shark (Galeocerdo cuvier) or a great hammerhead (Sphyrna mokarran) is quite another. Seeing the sharks briefly out of the water provided a quick glimpse of their sinewy, efficient design…truly a natural work of art. Regardless of size, shape, or species, the sharks were powerful, feisty, and awe-inspiring. The diversity in design is what makes sharks so fascinating!

Even just a quick peek of this tiger shark (Galeocerdo cuvier) reveals her strong muscles and powerful, flexible design.

A large tiger shark lies on a support framework made from reinforced netting. The shark and the structure are being lifted out of the water.
This female tiger shark was large enough to require the shark cradle. The reinforced netting on the cradle provided support for the 10.5 foot shark.

The shape of this sandbar shark’s (Carcharhinus plumbeus) head and eye is quite different from the tiger shark’s distinct design.

Even in the dark, the shape of the great hammerhead’s (Sphyrna mokarran) cephalofoil is unmistakable.

I envied the remora, or sharksucker, that was attached to one of the sharks we caught. Imagine being able to observe what the shark had been doing, prior to encountering the bait on our longline fishing gear. What did the shark and its passenger think of their strange encounter with us? Where would the shark swim off to once it was released back into the water? If only sharks could talk. I had many questions about how the tagging process impacts sharks. As we started catching and tagging sharks, I couldn’t help but think of a twist on the opening of MTV’s The Real World: “…To find out what happens…when sharks stop being polite…and start getting reeled.

Sadly for my curiosity, sharks have yet to acquire the ability to communicate verbally, despite their many advantageous adaptations over millions of years. To catch a glimpse of their actions in their watery world, scientists sometimes attach cameras to their fins or enlist the help of autonomous underwater vehicles (AUVs) to learn more. The secret lives of sharks… reality TV at its finest.

Underwater camera footage is beginning to reveal the answers to many of the questions my Kindergarten-5th grade students have about sharks:

How deep can sharks swim?

How big can sharks get? How old can sharks get?

Do sharks sleep? Do sharks stop swimming when they sleep? Can sharks ever stop swimming? 

Do sharks have friends? Do sharks hunt cooperatively or alone?

Is the megalodon (Carcharocles megalodon) still swimming around down there? (This is a very common question among kids!)

The answers vary by species, but an individual shark can reveal quite a bit of information about shark biology and behavior. Tagging sharks can provide insight about migratory patterns and population distribution. This information can help us to better understand, manage, and protect shark populations.

Various tools are spread out and used to weigh (scale), collect samples (scissors and vials), remove hooks (pliers, plus other instruments not pictured), apply tags (leather punch, piercing implement, and tags), and record data (clipboard and data sheet).
These tools are used to weigh (scales on bottom right), collect samples (scissors and vials), remove hooks (pliers, plus other instruments not pictured), apply tags (leather punch, piercing implement, and tags), and record data (clipboard and data sheet).

Using several low-tech methods, a great deal of information could be gleaned from our very brief encounters with the sharks we caught and released. In a very short amount of time, the following information was collected and recorded:

• hook number (which of the 100 longline circle hooks the shark was caught on)
• genus and species name (we recorded scientific and common names)
• four measurements on various points of the shark’s body (sometimes lasers were used on the larger sharks)
• weight (if it was possible to weigh the shark: this was harder to do with the larger, heavier sharks)
• whether the shark was male or female, noting observations about its maturity (if male)
• fin clip samples (for genetic information)
• photographs of the shark (we also filmed the process with a GoPro camera that was mounted to a scientist’s hardhat)
• applying a tag on or near the shark’s first dorsal fin; the tag number was carefully recorded on the data sheet
• additional comments about the shark

Finally, the hook was removed from the shark’s mouth, and the shark was released back into the water (we watched carefully to make sure it swam off successfully)!

A metal tag is marked with the number eight. This is one of 100 used in longline fishing.
Longline fishing uses 100 numbered hooks. When a fish is caught, it’s important to record the hook number it was caught on.

Two kinds of shark tags: plastic swivel tags used for smaller sharks and dart tags used for larger sharks.
Depending on the shark’s size, we either attached a swivel tag (on left and middle, sometimes called a Rototag or fin tag; used for smaller sharks) or a dart tag (on right, sometimes called an “M” tag; used for larger sharks).

Other fish were retained for scientific samples. Yellowedge grouper (Epinephelus flavolimbatus), blueline tilefish (Caulolatilus microps), and red snapper (Lutjanus campechanus) were some of species we caught and sampled. Specific samples from specific species were requested from various organizations. Generally, we collected five different samples:

• fin clips: provide genetic information
• liver: provides information about the health of the fish, such as the presence of toxins
• muscle tissue: can also provide information about the health of the fish
• gonads: provide information about reproduction
• otoliths: These bony structures are found in the inner ear. Similar to tree rings, counting the annual growth rings on the otoliths can help scientists estimate the age of the fish.

Samples were taken from this yellowedge grouper (Epinephelus flavolimbatus).

Samples were preserved and stored in vials, jars, and plastic sample bags, including a Whirl-Pak. These bags and containers were carefully numbered and labeled, corresponding with the information on the data sheets. Other information was noted about the fish, including maturity and stomach contents. Sometimes, photos were taken to further document the fish.

 

Personal Log

Thinking of the Oregon II as my floating classroom, I looked for analogous activities that mirrored my elementary students’ school day. Many key parts of the elementary school day could be found on board.

A 24-hour analog clock.
Sometimes, my students struggle to tell the time with analog clocks. The ship uses military time, so this 24-hour clock would probably cause some perplexed looks at first! We usually ate dinner between 1700-1800.

Weights, an exercise bike, resistance bands, and yoga mats.
Physical Education: Fitness equipment could be found in three locations on the ship.

A dinner plate filled with cooked vegetables.
Health: To stay energized for the twelve-hour shifts, it was important to get enough sleep, make healthy food choices, and stay hydrated. With lots of exercise, fresh air, and plenty of water, protein, and vegetables, I felt amazing. To sample some local flavors, I tried a different hot sauce or Southern-style seasoning at every meal.

A metal first aid cabinet.
There wasn’t a nurse’s office, but first aid and trained medical personnel were available if needed.

With my young readers and writers in mind, I applied my literacy lens to many of the ship’s activities. Literacy was the thread that ran through many of our daily tasks, and literacy was the cornerstone of every career on board. Several ship personnel described the written exams they’d taken to advance in their chosen careers. Reading and writing were used in everything from the recipes and daily menu prepared by Second Cook Arlene Beahm and Chief Steward Valerie McCaskill in the galley to the navigation logs maintained by Ensign Chelsea Parrish on the ship’s bridge.

A clipboard shows the daily menu for breakfast, lunch, and dinner.
The menu changed every day. You could also make your own salad, sandwiches, and snacks. If you had to work through mealtime, you could ‘save-a-meal,’ and write down your food choices to eat later. This was kind of like indicating your lunch choice at school. Instead of a cafeteria, food was prepared and cooked in the ship’s galley.

Shelves of books in the ship's library.
Library: The ship had a small library on board. To pass the time, many people enjoyed reading. (And for my students who live vicariously through YouTube: that sign at the bottom does say, ‘No YouTube’! Computers were available in the lab, but streaming wasn’t allowed.)

I often start the school year off with some lessons on reading and following directions. In the school setting, this is done to establish routines and expectations, as well as independence. On the ship, reading and following directions was essential for safety! Throughout the Oregon II, I encountered lots of printed information and many safety signs. Some of the signs included pictures, but many of them did not. This made me think of my readers who rely on pictures for comprehension. Some important safety information was shared verbally during our training and safety drills, but some of it could only be accessed through reading.

A collage of safety-related signs on the ship. Some have pictures, while others do not.
Without a visual aid, the reader must rely on the printed words. In this environment, skipping words, misreading words, or misunderstanding the meaning of the text could result in unsafe conditions.

A watertight door with a handle pointing to 'open'.
On a watertight door, for example, overlooking the opposite meanings of ‘open’ and ‘closed’ could have very serious consequences.

A watertight door with a handle pointing to 'closed'.
Not being able to read the sign or the words ‘open’ and ‘closed’ could result in a scary situation.

 

Did You Know?

Thomas Jefferson collected fossils and owned a megalodon tooth. The Carcharocles megalodon tooth was found in South Carolina. One of the reasons why Jefferson supported expeditions to lands west of the Mississippi? He believed that a herd of mammoths might still be roaming there. Jefferson didn’t believe that animal species could go extinct, so he probably liked the idea that the megalodon was still swimming around somewhere! (There’s no scientific evidence to support the idea that either Thomas Jefferson or the megalodon are still around.)

If Sharks Disappeared written and illustrated by Lily Williams

This picture book acknowledges the scariness of sharks, but explains that a world without sharks would be even scarier. Shown through the eyes of a curious young girl and her family, the book highlights the important role that sharks play in the ocean food web. As apex predators, sharks help to keep the ocean healthy and balanced.

The book includes some mind-blowing facts, such as the concept that sharks existed on Earth before trees. Through easy-to-follow examples of cause and effect, the author and illustrator explores complex, sophisticated concepts such as overfishing, extinction, and trophic cascade. The glossary includes well-selected words that are important to know and understand about the environment. Additional information is provided about shark finning and ways to help save sharks. An author’s note, bibliography, and additional sources are also included.

My first SCUBA gear! Age 3

My love for all things related to the ocean started at a very early age and grew into a passion by the time I graduated high school. As a young Floridian, exploring the beaches, boating through the intercoastal waterways, and visiting the Miami SeaQuarium were my way of life. When I was in elementary school, my family moved to Virginia and even though we spent the next ten years trading seahorses for Tennessee Walking horses, I still watched every rerun of Flipper and waited with anticipation for each Jacques Cousteau TV special. Then, when I was in high school, my grandparents moved from New Jersey to the Florida Keys and I was reunited once again with the beautiful underwater world that brought me such fascination. We spent our summers snorkeling, sailing, and fishing. In the evenings, we drove around searching for the elusive Key Deer. When we visited the Dolphin Research Center and the Turtle Hospital, I was shocked to learn that my beloved ocean was facing some serious threats.

As I entered college, my interest transformed from a hobby to a lifestyle. I earned my first SCUBA certification, participated in my first coastal clean-up, and volunteered for restoration projects and turtle walks. I signed up for every life science course I could find. In my senior year at Stetson University, I registered for a class before I even knew what the title meant. Ornithology, with Dr. Stock. I found myself canoeing through alligator-infested waterways to investigate snowy egret rookeries, hiking through the forest at 5am to identify birds by only their calls, and conducting a post-mortem investigation on one of his road-kill specimens to determine its cause of death. Dr. Stock’s class was so different than anything I had experienced. I was in my element. I found myself constantly wanting to learn more. Not just about the organisms around me, but about how to fix the negative impacts we have on their environment. As I learned, I became motivated to teach others about what they could do to make a difference. My passion for teaching was born.

It is hard to believe that I have been teaching science in Hillsborough County for almost twenty years and that approximately 3,000 students have filled the chairs of my classroom. Years ago, I realized that even though we are located in west-central Florida, many of my students have little involvement with the ocean or our local beaches. I decided to change that fact by extending my classroom outside of my four walls.  In true Dr. Stock fashion, I attempt to bring the ocean to life for my students through field trips, restoration projects, and guest speakers. With the help of some amazing organizations like the Florida Aquarium, Tampa Bay Watch, and Keep Tampa Bay Beautiful, we have participated in many activities to help us learn about the ocean and about how to remedy our impacts.

 

 

We also love to get out in nature and explore the splendor that awaits us. In the pictures below, students from Plant High enjoy a day at the Suncoast Youth Conservation Center where we participated in fishing and kayaking clinics and learned about protecting our local estuarine species.

A day of adventure focused on the importance of our beautiful estuaries!

As I head out for two weeks on NOAA Ship Oregon II, I am leaving my classroom and students behind but I know that the value of what I will bring back to them far outweighs the short time I will be away. I hope through my experience my students will see that you are never too old to learn something new and that even the teacher can improve her knowledge.

I am eager to develop first-hand experience with the technology and research methods currently being used to study the ocean. I look forward to meeting the scientists and the crew of my ship and learning about all of the career opportunities that are available to my students through NOAA. I am ready to turn my NOAA education into lessons that will benefit my students and infuse my curriculum with new life.

I cannot wait to see the beautiful sunsets over the gulf and maybe I’ll even catch a few sunrises. I am hoping for the occasional visit from a whale, a dolphin, or a sea turtle. Who knows? Maybe I will even get a chance to see a few of my favorite ornithological species!

Counting down … 12 days to go.

Fair Winds! 

Today’s Shout Out: To Mr. Johnny Bush (Plant High School Principal), Mr. Larry Plank (SDHC Director of STEM), and Mr. Dan McFarland (SDHC Science Supervisor) for all of their support in making this trip possible for me.

Science and Technology Log

Over the past few days, we’ve fished a mix of station depths, so I’ve gotten to see a number of new species as we’ve moved out into deeper waters.

At a C station, which is a station at depths between 183 and 366 meters, we caught a Mako Shark (Isurus oxyrinchus).  This catch was so unexpected that a number of crew members ventured out to the well deck to snap a picture.  She was a beautiful juvenile between 1-2 years old.

I also saw my first kingsnake eel, a long eel with a set of very sharp teeth.  On a later station, we caught a juvenile that we were able to bring on deck and examine.  We also caught a Warsaw grouper (Hyporthodus nigritus), which had parasites on its gills and in its fins.  Gregg Lawrence, a member of the night shift on loan from Texas Parks and Wildlife Coastal Fisheries unit, and I removed the otoliths and took samples of the parasites.

Dissecting a Warsaw Grouper

We had one catch that brought in 20 Red Snappers.  Red Snappers are brought on deck, and a number of samples are taken from each one of them for ongoing assessment of the Red Snapper population.  In addition to the otoliths, which allow the scientists to determine the age of the fish, we also take samples of the gonads, the muscle, the fins, and the stomach.  These allow the scientists to perform reproductive and genetic tests and determine what the snappers ate.  While 4 members of the science team onboard collected samples, Caroline Collatos, the volunteer on the day shift, and I insured that the samples were properly packaged and tagged.  Everyone working together allowed the process to run smoothly.

On the latest B station, which was about 110 meters deep, we caught a number of species, some of which I had not gotten to see yet.  In addition to Gulf smoothound sharks (Mustelus sinusmexicanus), we caught a Scalloped hammerhead shark (Sphyrna lewini) and a Sandbar shark (Carcharhinus plumbeus) that we had to cradle due to their size.  The Sandbar shark was a bit feisty, but I got the chance to tag her before we released her.

We work in the rain.  Thankfully, they had some extra rain gear for me to put on, so that I would not get drenched while we were setting the line.  For the most part, the rainstorms have been sprinkles, but we did have one downpour while we were going toward a station.

Personal Log

Between setting lines, I have been busy checking up on my studenats’ work back in Memphis.  One of the great things about having a one-to-one school is that the students are able to do their work on Microsoft Teams and turn it in for me to grade it thousands of miles away.  I have loved seeing their how they are doing, and answering questions while they are working, because I know that they are learning about the cell cycle while I am out at sea learning about sharks.

One of the things that has really surprised me over the past week is how much my hands hurt.  It was unexpected, but it makes sense, given how much of the work requires good grip strength.  From insuring that the sharks are handled properly to clipping numbers on the gangions to removing circle hooks from fish on the lines, much of the work on the science team requires much more thumb strength than I had thought about.  I know my students have commented that their hands hurt after taking notes in my class, so I thought they would get a kick out of the fact that the work on the ship has made my hands hurt.

Did You Know?

Sharks are able to sense electrical fields generated by their prey through a network of sensory organs known as ampullae of Lorenzini.  These special pores are filled with a conductive jelly composed primarily of proteins, which send the signals to nerve fibers at the base of the pore.

Quote of the Day

Remove the predators, and the whole ecosystem begins to crash like a house of cards. As the sharks disappear, the predator prey balance dramatically shifts, and the health of our oceans declines.

Science and Technology Log

We’ve been out at sea for three full days now and have traveled along the Gulf coast from Alabama to Texas.  The Science Team has run mostly shallow longline sets during this time, meaning that we have fished in depths from 9 to 55 meters.  As we move forward, we will fish stations at these depths and stations at depths of 55 to 183 meters, and from 183 to 366 meters.  The locations of the stations are randomized based on depth and the area that is being fished.  Due to the weather that hit south Texas the week before we joined this leg of the survey, we have been fishing the area that was impassable on the last leg of the survey.

As a member of the science team, there are five jobs that need to be done on each side of the set.  When the line is being cast, someone needs to release the highflyer, clip numbers, sling the bait, work the computer, or cleanup.  When the line comes in, there is a data collector, 2 fish handlers, a hook collector, and the computer person.  The highflyer is the marker that is put on either end of the line, so that the line can be seen from the bridge.  The data that is collected on paper and on the computer on each fish includes the number of the hook that they are on, species, length, and gender.  Additionally, some sharks are tagged and a fin clip is taken.

After a line is set, we check the water using a CTD (Conductivity Temperature Depth) Probe.  It has a GoPro video recorder that takes a video of the water and the sea floor at the site of the line.

A few of the highlights from the catches so far:  We had one catch that was coming up with mostly empty hooks, but then we caught a scalloped hammerhead shark (Sphyrna lewini).  The shark was large enough that we used a cradle to pull it up to deck level.  I got to insert the tag right below the dorsal fin.

We had another survey that caught 49 sharks, including Atlantic Sharpnose Sharks (Rhizoprionodon terraenovae), Blacknose Sharks (Carcharhinus acronotus), Spinner Sharks (Carcharhinus brevipinna), and Blacktip Sharks (Carcharhinus limbatus).  Between these, we had a number of lines that brought up some sharks and a few Red Snapper (Lutjanus campechanus).  I have been able to dissect some of the Red Snapper, and collect their otoliths, which are their ear bones.

In the time between setting and retrieving lines, one of the ways we kept ourselves busy was by cleaning shark jaws that we had collected.  I look forward to using these in my classroom as an example of an apex predator species adaptation.

Personal Log

During much the 12 hours of off time, I spend my time in my bunk.  Working for 12 hours in the hot sun is exhausting, and it’s nice to have the room to myself while I try to get some rest.  Though I share a bunk with another member of the Science Team, we work opposite shifts.  So, while I’m on deck, she’s sleeping, and visa versa.  As you can see, my daughter sent me with her shark doll, which I thought was appropriate, given that I was taking part in shark research on this ship.

While we were going slow one day, we had a pod of dolphins who swam along with us for a while.  They were right beside the ship, and I was able to get a video of a few of them surfacing next to us.

Did You Know?

Many shark species, including the Atlantic Sharpnose shark, are viviparous, meaning they give birth to live young.  These sharks form a placenta from the yolk sac while the embryo develops.

Science and Technology Log

My first day onboard was spent following around 2nd Engineer Will Osborn.  Will is an officer in the Merchant Marines, and a NOAA Augmentation Pool Engineer assigned to the Oregon II.  He invited me to follow him around and learn how the engineers prepare the ship for sea.  One of the duties of the engineers is to check the liquid levels of each of the tanks prior to sailing.  They do this by performing soundings, where they use a weighted measuring tape and a conversion chart to determine the number of gallons in each of the tanks.

 

The engineering team then prepared the ship to sail by disconnecting shore power and turning on the engines aboard ship.  I got to flip the switch that disconnects the ship from shore power.  I followed the engineering team as they disconnected the very large cable that the ship uses to draw power from shore.  I then got to follow 2nd Engineer Will as he turned on the engines aboard ship.

Once we set sail, the science team met and discussed how longline surveys would work.  I am on the day shift, which is from noon to midnight.  We got the rest of the day, after onboard training and group meetings, to get used to our new sleep schedule.  Because I was on the day shift, I stayed up and got to watch an amazing sunset over the Gulf.

Our second day out, we set our first two longlines.  The first one was set before shift change, so the night shift crew bated the hooks and set the line.  My shift brought the line in, and mostly got back unbaited hooks.  We got a few small Atlantic Sharpnose (Rhizoprionodon terraenovae) sharks on the line, and used those to go over internal and external features that differentiated the various species we might find.

 

After the lines were in, it was time for safety drills.  These included the abandon ship drill, which required us to put on a submersion suit, which is affectionately referred to as a Gumby suit.  You can see why below.  It was as hard to get into as it looks, but it will keep you warm and afloat if you end up in the water after you abandon ship.

I have learned a few rules of the boat on my first days at sea.  First, always watch your head.  The stairwells sometimes have short spaces, and you have to make sure not to hit them on your way up.  Second, always keep a hand free for the boat.  It is imperative at sea that you always have a hand free, in case the boat rocks and you need to catch yourself.  Third, mealtimes are sacred.  There are 31 people aboard the boat, with seating for 12 in the galley.  In order for everyone to get a chance to sit down and eat, you can’t socialize in the galley.

Did You Know?

In order for the crew to have freshwater to drink, the Oregon II uses a reverse osmosis machine.  They create 1000-1200 gallons of drinkable water per day, running the ocean water through the reverse osmosis generator at a pressure of 950 psi.

Personal Introduction

Greetings to those following my adventure from afar.  My name is Kristin Hennessy-McDonald, but my students and fellow faculty call me Dr. Hen-Mc.  I am so excited to have been selected to be a member of the NOAA Teacher at Sea Program aboard the Oregon II.  I am the science lead at T-STEM Academy at East High School, where I teach Honors Biology.  My path to the classroom was far from straight.  I attended the University of Notre Dame, where I earned a B.S. in Biology.  I then continued my academic path at the University of Alabama, Birmingham, where I earned my PhD in Cell Physiology.  After spending a little less than 3 years at St. Jude Children’s Research Hospital, I had an epiphany.  I found that I enjoyed sharing my passion about science more than doing research at the bench.  I made the decision to transition to the classroom and have not looked back.  8 years later, I have found my home at T-STEM, and my family in Team East.

The journey to boarding the Oregon II has been a long one, but well worth it.  When my boss brought the opportunity to me, I applied with hope.  When I got the acceptance letter, I gasped and started jumping up and down in my classroom.  My students were confused, but then excited when they found out that I had gotten this opportunity.  I teach many of the same students who were in that class, and they have all been sharing in my excitement over the past months as I have prepared for this adventure.

I have always been fascinated by water.  From the time I was a small child, my parents would have to watch carefully when we went to the pool or the beach, because I was liable to jump right in.  As I grew up, that love of water has remained, and I spend time each summer on the Gulf.  I am thrilled to have a chance to study ecosystem of the Gulf of Mexico, and see things that I only read about in National Geographic magazine.

I have passed my love of water on to my daughter.  Beth is the same way I was when I was young.  She wants to run into the water, to play in the waves.  She sees the beauty of the sea, watching dolphins alongside the boat when we take trips to Ship Island out of Gulfport, MS.  I look forward to sharing my adventures at sea with her.  I am sad to leave her and my husband for two weeks, but grateful that they waved me off on my adventures with a smile.

I began my career as a teacher because I wanted to share my love of science with young people.  I dreamed of someday being a child’s gateway to the wonders and knowledge of science.  While none of my students have stood on a desk reciting Whitman, some of my students have allowed my love of science to guide them along science career paths.  When I joined Team East at T-STEM Academy at East High School, I knew that I was in a place that would foster the idea of learning by doing.  I wanted to exemplify that going on this trip.  I cannot wait to bring all of the knowledge and experiences of this trip back to my classroom.  Instead of just sharing case studies of Gulf Coast ecosystems, I will be able to share what I learned as a NOAA Teacher at Sea.

The one thing that pops into most people’s mind when they hear the word ‘shark’ is their sharp teeth.  Surprisingly, not all sharks have sharp teeth.  The diet of a shark determines the shape of their teeth.  The picture below is a set of jaws from two different species of sharks.  The jaws on the right are from an Atlantic sharpnose shark (Rhizoprionodon terraenovae), and the set of jaws on the left is from a gulf smoothhound (Mustelus sinusmexicanus).  The Atlantic sharpnose shark possesses small razor blade-like teeth because their diet consists of many different species of fish, as well as worms, crabs, and mollusks.  The gulf smoothhound possess teeth that are shorter, less sharp, and more closely packed together.  Their diet consists mainly of crustaceans and smaller species of fish.

Day Crew.jpg
Shark/Red Snapper Survey Day Crew

We completed our last haulback tonight and we caught a whopping 48 fish.   Just before the haulback I watched the sun set one last time before I head home tomorrow.  These past two weeks have been so rewarding for me professionally and personally.  There were times when I felt like a college intern again, and I loved the feeling of not knowing all the answers.  So often my students think I have the answer to everything, and it was so refreshing to be back in their shoes for two weeks.  The NOAA scientists and fisherman expressed so much patience with me.  It reminded me that my students are learning most of the material in my classroom for the first time, and they will be more successful if I show them patience as they work through understanding the many details that I throw at them in one class period.

I most excited to get back to my family.  I fly in very late tomorrow night so I will not see my kids until they wake up on Saturday morning.  I can’t wait to see the look on their faces when they see that Mommy is finally home!  Once everyone is awake I am driving straight to Dunkin’ Donuts for an iced coffee.

Green over white, trawling at night.

White over red, pilot ahead.

Red over red, captain is dead.

When driving a vessel like the Oregon II it is always important to have the ability to analyze the radar, locate other vessels in the water, and determine their current situation by reading their mast lights.  Line 1 of the poem describes a vessel that is currently sailing by use of wind without the use of an engine, line 2 describes a boat engaged in fishing operations, line 3 indicates that the vessel is currently trawling a net behind the boat, line 4 indicates that the vessel is a pilot boat (a boat containing a pilot, who helps guide larger tanker and cargo ships into harbors), and line 5 of the poem is used for a situation when the vessel is not operating properly and other vessels should steer clear.

blacktip shark
NOAA Scientist, Adam, Pollack, and I measuring and tagging a blacktip shark (Carcharhinus limbatus)

There are currently three named storms in the Atlantic, including a category 4 hurricane (Florence) that is headed towards the Carolinas.  I have never experienced a bad storm while out on the water.  The waves the last 24 hours have ranged from 3-5 feet, with an occasional 8 foot wave.  We have changed our port call location and will now be going back to Pascagoula, Mississippi instead of Galveston, Texas.  There was also no internet for part of the day so my team and I sat in the dry lab and told ghost stories.  I was also introduced to the “dinosaur game” in Google Chrome, which is sort of like a low budget Mario.  Apparently it is the dinosaur’s birthday so he is wearing a birthday hat.

I am still making the most of every minute that I am out here.  Our last haulback was very active with many large blacktip sharks.  It is a workout trying to handle the sharks on deck, while collecting all required data, and getting them back in the water as fast as possible.  I am loving every second!

 

 

Did you know:

Sharks possess dermal denticles (skin teeth) that makes their skin feel rough when running your hand tail to nose.  Shark skin used to be used as sandpaper before it was commercially manufactured.  It can also give you shark burn, which is sort of like a rug burn, if the shark brushes up against you.

In addition to collecting data on the many species of sharks in the Gulf of Mexico, this survey also collects data that will go towards assessing the population of red snapper (Lutjanus campechanus).  One piece of evidence that is collected from the red snapper is their two distinct otoliths.  Otoliths are structures that are used for balance and orientation in bony fish.  One fascinating characteristic of the otolith is that they contain natural growth rings that researchers can count in order to determine the age of the fish.  This information is important for stock assessment of the red snapper in the Gulf of Mexico.

Personal Log:

I would have to say that the hardest part about being out at sea is not being able to see Coral and Kai.  I miss them so much and think about them nonstop.  Coral is at a very curious stage in her life (I hope the curiosity stays with her forever) and I cannot wait to get home and tell her about all the animals that I have been lucky enough to witness on this adventure.  Kai is just the sweetest little boy and I can only imagine the way he will react when I get home.

Bearing Down on the Oregon II

I am very busy on the boat and when there is down time my team and I are getting shark lessons from the incredibly intelligent Chief NOAA Scientist, Kristin Hannan, or we are in the movie room catching up on all the Annabelle movies.  It is almost impossible to get scared while aboard a ship.  It may seem that many things could go wrong, but the lights are always on and someone is always awake.  It is the perfect environment to watch any horror film because this atmosphere makes it much less scary.

Probably the scariest thing that is happening on this boat is the amount of weight I have gained.  All of the meals are delicious and they come with dessert.  It is kind of nice to not have to worry about going to the gym or staying on a normal routine.  Life is always so hectic day to day when I am at home, but being out here on the water gives me time to relax and reflect on the amazing people I have in my life that made this opportunity possible.

I am sad to report that the Chicago Bears lost tonight to Greenbay, but I did show support for my team!  I think the best part of the day was when I was on the bow of the boat and Kristin announced over the radio that the Bears were winning 7 to 0.  It is exciting being out here seeing everyone cheer for their fantasy team, as well as their home town team.

Science and Technology Log:

After a long two day cruise to the southern tip of Texas, we finally started fishing.  I learned quickly that everyone has a job, and when you are done with your job, you help members of your team complete their tasks.  The coordinates of all of the survey locations are charted using a program called Novel Tec, and once the captain has determined that we have reached our designated location, the fun begins.  To deploy the longline there are many important responsibilities that are delegated by the Chief NOAA Scientist.

#1- All scientists work together to bait 100 hooks with mackerel (Scomber scombrus).

 

 

 

 

 

High Flyer

#2- High-Flyer Release – Once the long line has been attached to the high-flyer, it is released from the stern of the boat.  The high-flyer consists of a buoy to keep it above water, and a flashing light, so we know the exact location of the beginning of the longline.

 

 

 

 

 

Attaching a weight

#3 Weight Attachment – A NOAA fisherman is responsible for attaching the weight at the appropriate distance, based on the depth of that station to ensure the gear is on the sea floor.  This  also keeps the high-flyer from drifting.  Alongside the weight, a TDR is attached to the line, which records temperature and depth.

 

 

 

numbered hooks
Each baited hook is identified with a number.

 

 

 

#4 Numbering of baited hooks – After the first weight goes out, one by one the gangions are numbered and set over the edge of the ship, but not let go.  A gangion consists of a 12ft line, a baited hook, and hook number.

 

 

 

 

 

 

Attaching the Hooks
Attaching the Hooks

# 5 Hook Attachment – A NOAA fisherman will receive one gangion at a time, and attach it to the line.  Another weight is attached to the line after 50 hooks have been deployed, and once all 100 hooks are deployed the final weight is attached.  Then the line is cut, and the second high-flyer is attached and set free to mark the end of the survey area.  This process goes fairly quickly, as the longline is continuously being fed into the water.

 

Data Collection

#6 Data Collection – Each piece of equipment that enters the water is recorded in a database on the computer.  There should always be 2 high-flyers, 3 weights, and 100 gangions entered into the database.

 

 

 

 

 

Scrubbing buckets

#7 Bucket Clean-up – The buckets that were holding the baited hooks need to be scrubbed and prepared for when we haul the line back in.

 

 

 

 

 

 

Once all of the gear is in the water we wait for approximately one hour until we start to haul back each hook one by one.  The anticipation is exciting to see if a shark or other fish has hooked itself.

Personal Log

I would say that my body has fully adjusted to living at sea.  I took off my sea sickness patch and I feel great!  Currently, Tropical Storm Gordon is nearing to hit Mississippi this evening.  We are far enough out of the storm’s path that it will not affect our fishing track.  I am having the time of my life and learning so much about the Oregon II, sharks, and many other organisms that we’ve seen or caught.

NOAA Ship Oregon II creates freshwater via reverse osmosis.  Sea water is pumped in and passed through a high pressure pump at 1,000psi.  The pump contains a membrane (filter), which salt is too big to pass through, so it is disposed overboard.  The clean freshwater is collected and can be used for showering, cooking, and drinking.  In addition to creating freshwater, the engineers are also responsible for the two engines and the generators.

Science and Technology Log

Life at sea provides fathoms of real-life examples of the nonfiction text structures I teach my students to identify: description, order and sequence, compare and contrast, fact vs. opinion, problem-solution, cause and effect, and several others.

While on the Oregon II, I was very fortunate to observe a dive operation that took place.

Here’s how an account of the dive operation might read for my elementary school students. Embedded in the text, I’ve included opportunities for developing readers to use context clues, to notice words that signal order/sequence (first, next, then…), to notice words that signal compare and contrast (similar, unlike), etc.

Today’s lesson: Problem-Solution.

Problem: Sometimes, the hull (or watertight body) of a vessel can become encrusted with marine life such as algae or barnacles. This is called biofouling. To prevent biofouling, underwater surfaces are inspected and cleaned regularly. To further prevent creatures from making the body of the Oregon II their home, the hull is painted with a special anti-fouling paint.

Occasionally, man-made materials, like rope and fishing gear, can get tangled in the equipment that sits below the surface of the water, such as the rudder or propeller.

Underwater GoPro camera footage suggested that a piece of thick plastic fishing line (called monofilament) was near the Oregon II’s bow thruster. The bow thruster, located in the front of the ship, is a propulsion device that helps to steer the ship to the port (left) or starboard (right) side. This makes navigating and docking the 170-foot ship easier. When the powerful bow thruster is engaged, the entire ship rumbles, sounding like a thunderous jet soaring through the sky.

Something like entangled fishing line is problematic for navigation and safety, so the line must be removed if found. Because the bow thruster is located beneath the water’s surface, this task cannot be completed while on the ship. So how can the crew remove any tangled line and inspect the hull for damage?

Solution: Divers must swim under the ship to inspect the hull. If fishing line is suspected, divers can investigate further. This opportunity to “inspect and correct” allows them to take a closer look at the hull. If fishing line or other damage is found, divers cut away the line and report the damage. Routine hull inspections are part of regular ship maintenance.

A pre-dive briefing on the bridge
Led by Divemaster Chris Nichols, also the Oregon II’s Lead Fisherman and MedPIC (Medical Person in Charge), the team gathered on the bridge (the ship’s navigation and command center) to conduct a pre-dive safety briefing. Nichols appears in a white t-shirt, near center.

The entire process is not as simple as, “Let’s go check it out!” NOAA divers must follow certain rules and safety regulations.

First, the Oregon II’s dive team developed a Dive Operations Plan to investigate the bow thruster and hull. Dive details were discussed in a pre-dive briefing, or meeting. The Diving Emergency Assistance Plan (DEAP) was reviewed and a safety checklist completed.

The team prepared to send two divers, Lead Fisherman (LF) Chris Nichols and Navigation Officer Ensign (ENS) Chelsea Parrish, to inspect the bow thruster and remove any fishing line if needed. For this task, they carried scrapers and line-cutting tools.

To prepare for the dive operation, ship navigation plans were made. Equipment beneath the boat was secured. This ensured that the divers would be kept safe from any moving parts such as the propeller or rudder.

Next, announcements were made before and after the dive to notify the entire ship that divers would be entering and exiting the water. That way, everyone on board knew to stop any fishing activity and avoid putting fishing gear in the water.

Two dive safety flags hoisted over the Oregon II.
To let nearby vessels know that divers are in the water, two flags are hoisted. The scuba flag (red and white) indicates “diver down,” and the International Code of Signals flag ‘Alfa’ (blue and white; sometimes spelled ‘Alpha’) lets other vessels know that the ship is engaged in a dive operation. This tells other vessels to ‘keep well clear at slow speed’.

International Code of Signals flags are stored on the bridge.
Maritime communication flags are stored on the bridge. Learn your A, B, Seas: https://en.wikipedia.org/wiki/International_maritime_signal_flags

During the pre-dive briefing, procedures were reviewed and agreed upon. If needed, clarifying questions were asked to make sure that everyone knew and understood exactly what to do. This was similar to the ‘Checking for Understanding’ that I do with my students after giving directions.

Then the team agreed upon a dive time and a maximum diving depth. In this case, the team planned to dive a maximum of 25 fsw (feet of sea water). The surrounding water was about 160 feet deep.

A smaller rigid rescue boat floats nearby, prepared to assist divers if needed.
A smaller, 18-foot rigid rescue boat was launched from the Oregon II, prepared to assist the divers in the water if needed.

On the deck of the Oregon II, a Topside Supervisor and Line Tender kept watchful eyes on the divers. Chief Boatswain (pronounced “boh-suhn”) Tim Martin was the standby diver, prepared to provide immediate assistance to the other divers if needed.

Divers perform a safety check before entering the water.
Before entering the water, the divers checked one another’s gear for safety.

Divers perform a safety check before entering the water.
Potential risks and hazards, such as currents, obstacles, and dangerous marine life, were identified ahead of time. Multiple solutions were in place to minimize or eliminate these risks. Checking equipment before entering the water ensures that divers are prepared.

As the divers prepared to enter the water, the rest of the team was equally well prepared with checks, double-checks, back-up plans, communication, and contingency (emergency) plans. Hopefully, emergency plans are never needed during a dive operation, but just in case, everyone was well-trained and prepared to jump into action.

A diver enters the water with a Giant Stride.
Plans for entry into the water and exit from the water were reviewed in the pre-dive briefing. In this case, Lead Fisherman Chris Nichols entered the water with an entry method called a Giant Stride.

Ensign Chelsea Parrish enters the water with a Giant Stride. An exit plan, plus two back-up exit options, were also reviewed beforehand. If needed, the divers had three possible ways to exit the water.

The water was calm and the weather fair. The divers signaled to the ship that they were OK in the water, and slipped beneath the surface. Soon, the only trace of them was a lighter blue trail of bubbles.

Divers at the surface of the water, preparing to dive.
The divers are OK and ready to dive. For breathing under water, the divers used compressed air in tanks. Because this was open circuit scuba (self-contained underwater breathing apparatus) equipment, air bubbles could be seen in the water once they disappeared beneath the surface.

Divers leave behind a trail of bubbles as they descend.
As divers descended, air bubbles could be seen beneath the surface. For safety, a Reserve Air Supply System (RASS) was also worn by each diver.

This was a working dive. Unlike recreational diving, this was not the time for the divers to leisurely swim and explore, but to follow the plan precisely. To communicate with each other under water, hand signals were used.

Divers surface after the dive.
While in the water, the divers also practiced a ‘sick diver’ drill to rehearse what to do if a diver needed medical attention. Similar to a fire drill or other safety drill, but performed in the water, this was one of several drills performed on the Oregon II.

The dive team holds a post-dive debriefing on the ship's bridge.
After the dive was completed, a post-dive briefing was held to review and critique the dive operation. The dive team discussed how the dive actually went, in comparison to the dive plan. This was similar to the reflection I do after teaching lesson plans.

The divers reported back on the condition of the bow thruster and hull, as well as the dive conditions. They discussed their equipment, the undercurrent, and how they felt while under the pressure of the water. Dive data was collected from each diver and recorded on a form. The divers reached a depth of 21 feet.

Success! After inspecting the hull, the divers reported that they didn’t see any fishing line on the bow thruster or damage to the hull. Instead, they saw some small fish called jacks and some moon jellies drifting by.

Diving gear is removed, rinsed, and dried.
Finally, the scuba equipment is removed and rinsed with fresh water. Once dry, it will be carefully stowed away until the next dive.

Dive operations don’t happen often on the Oregon II. Normally, the team practices and performs their dives in a swimming pool in Mobile, Alabama. This dive near the Florida Keys was the first at-sea operational dive in two years as a full team—a rare and exciting treat to witness! 

Personal Log

This reflection captures my own dive into the world of longline fishing. Switching roles from educator to student, this is also where I transition from writing for my students to writing for my peers and colleagues.

Two pairs of gloves and a hard hat
Gloves for handling bait (left) and grippy gloves for handling live fish (right)

Every time I attempt something brand new, some optimistic part of me hopes that I’ll be a natural at it. If I just try, perhaps I’ll discover some latent proclivity. Or perhaps I’ll find my raison d’être—the reason why I was placed on this planet.

So I try something new and quickly recognize my naïveté. Many of these new skills and sequences are difficult, and I’m slow to master them. I compare my still-developing ability to that exhibited by seasoned veterans, and I feel bad for not grasping it quickly.

Spoiler alert: Longline fishing may not be my calling in life.

Life on and around the water, however, suits me quite well. As I’ve acclimated to life on a ship, the very act of being at sea comes naturally. Questions and curiosity flow freely. An already-strong appreciation for the water and its inhabitants deepens daily. And while I may not learn new concepts quickly, I eventually learn them thoroughly because I care. This journey has been a culminating opportunity in which I’ve been able to apply the nautical knowledge and marine biology fun facts I’ve been collecting since childhood.

Much of the daily work is rote, best learned through repetition, muscle memory, and experience. Very little of it is intuitive or commonsense, and my existing nautical know-how isn’t transferable to the longline gear because I’ve never handled it before.

Longline gangions stored in a barrel
At first, making sense of the various steps and equipment used in longline fishing felt like a jumbled, tangled barrel of gangions.

At any point during my twelve hour shift, I’m keeping track of: the time, several other people, several locations on the ship, my deck boots (for working outside), sneakers (for walking inside), personal flotation device (PFD), sun hat, hard hat, bait gloves (for setting bait on hooks), grippy work gloves (for handling equipment and slippery, slimy fish), water bottle, camera, and rain gear…not to mention the marine life and specialized equipment for the particular task we’re performing.

A view of the stern shows a bait cooler, table, longline clips/hook numbers, bait barrels, high flyers, buoys, and other longline fishing equipment.

Somewhere, Mr. Rogers is feeding his fish and chuckling with approval every time I sit down to swap out my deck boots several times a day.

Swapping out my sneakers for deck boots…again.

There’s a great deal of repetition, which is why it’s so frustrating that these work habits haven’t solidified yet. It should be predictable, but I’m not there…yet. Researchers believe it takes, on average, more than two months before a new behavior becomes automatic. Maybe I’m being hard on myself for not mastering this in less than two weeks.

Unlatch the door. Relatch the door. Fill water bottle. Sunscreen on. Sneakers off. Boots on. Boots off. Sneakers on. Bait gloves on. Bait gloves off. Work gloves on. Work gloves off.

It seems simple enough in writing, but I struggle to remember what I need to be wearing when, not to mention the various sub-steps involved in longline fishing and scientific research.

Clouds over shining water and the horizon
How do you catch a cloud and pin it down?

During the dive operation, I ventured up to the bow for a better vantage point. Alone on the bow, glorious water teemed with fascinating marine life as far as I could see. Below me—and well below the surface—an actual dive operation was taking place: an opportunity to apply the diving knowledge I’ve absorbed and acquired over the past several years.

If I were in a certain movie musical, I would have burst into song, twirling in circles on the bow, unable to resist the siren song of the sea. (And, as I’ve discovered from handling a few of the slimier species we’ve caught, the depths are alive…with the stench of mucus. And its slimy feel.)

As I struggle to keep track of all of the routines, equipment, and fishing gear, I feel like Maria in the opening scene of The Sound of Music. Lost in reverie and communing with nature, she suddenly remembers she’s supposed to be somewhere and rushes off to chapel, wimple in hand. She’s supposed to be wearing it, of course, but at least she made it there and remembered it at all.

My Teacher at Sea path was filled with an Alpine range of mountains to climb, but I climbed every mountain, and I’m here on the Oregon II. All of the hard work I’ve put in for the past ten years culminated into that harmonized, synchronous moment on the bow…

And then I remembered that my shift was starting soon, so I dashed off, PFD in hand.

I know that I’ll need a PFD at some point. And my gloves. And my boots. And a hard hat. I have them all at the ready, but I’m not always sure which one to wear when. As I fumble through the transitions, routines, and equipment, I sympathize with Maria’s difficult search for belonging. I certainly mean well, and my appreciation for the water around us cannot be contained.

A very happy Teacher at Sea
Being on and around the water fills me with joy…

Eventually, Maria realizes that she’s better suited to life as a governess and later, a sea captain’s wife. I’m discovering that perhaps I was not destined to be a skilled longline fisherman, but perhaps there is some latent proclivity related to the life aquatic. I may not always know which equipment to use when, but I know—with certainty—that I definitely need the ocean.

Taking a curtain cue from Maria, perhaps I could fashion a dress or a wetsuit from the curtains hanging near my berth…?

Did You Know?

Sharks secrete a type of mucus, or slime, from their skin. The mucus provides protection against infection, barnacles, and parasites. It also helps sharks to move faster through the water. Ship builders are inspired by sharks’ natural ability to resist biofouling and move through the water efficiently.

Students may be surprised to learn that barnacles are not only marine animals, but they begin their life as active swimmers and later attach themselves permanently to a variety of surfaces: docks, ships, rocks, and even other animals.

Barnacles by Lola M. Schaefer is part of the Musty-Crusty Animals series, exploring how the animal looks and feels, where it lives, how it moves, what it eats, and how it reproduces. This title is part of Heinemann’s Read and Learn collection of nonfiction books for young readers. Other creatures in the series include: crayfish, hermit crabs, horseshoe crabs, lobsters, and sea horses. These books are a great introduction to nonfiction reading skills and strategies, especially for younger readers who are interested in fascinating, unconventional creatures.

Science and Technology Log:

When one hears that there is an ET aboard NOAA Ship Oregon II, they might imagine E.T., the extra terrestrial, wearing a sailor hat and driving the boat.  Fortunately for everyone aboard, E.T. is not driving the boat and the ET aboard the Oregon II is Lester S. Andreasen.  Lester, known as Les, is a rotational Electronic Technician (ET).  Les is responsible for the network and communication while out at sea.  He also provides support to the NOAA scientists by assisting them in maintaining shipboard scientific data collection.

Les Andreason, Electronics Technician
Les Andreason working in his ‘office’ aboard NOAA Ship Oregon II.

Prior to his career aboard NOAA Ship Oregon II, Les was in the Navy for 23 years.  His first station right out of boot camp was Key West, FL.  That is where he learned about navigational radar, and preformed corrective and preventative maintenance on electronics on the unique squadron of Patrol Hydrofoil Missiles (PHMs).  Les started in the Navy as an electronic technician seaman (E3), and worked his way to a command master chief (E9).  When he left the Navy he began his career aboard dynamic positioning ships.  When the oil field began to struggle, Les was hired by NOAA.

Les describes NOAA Ship Oregon II as a “fun ship”, as he really enjoys the people.  He finds it fascinating to see how the crew interacts with the scientists while completing the shark surveys.  Les’s advice to anyone who wants to pursue a career as an ET would be to study computer science, mathematics, or computer engineering.  I guess he is a little like E.T. the extra terrestrial, because without Les we wouldn’t be able to ‘Phone Home’ and talk to our families or anyone on shore.

Personal Log:

We have been cruising for two days now, and won’t start fishing until tonight.  Since I have had some extra time on my hands, I got to try out the nifty workout equipment.  I did a circuit of 2 minutes on the bike, 20 kettle bell swings, and 10 dumbbell squats.  I completed 10 rounds.  Then I proceeded to the stern where I did planks, sit-ups, and stretched.  It was very relaxing to be able to look out over the water.  I didn’t even feel like I was working out because it was so peaceful.

Science, Technology, and Career Log:

I arrived to NOAA Ship Oregon II on Thursday afternoon, August 30th, after traveling from Chicago.  The very first person I met aboard the ship was my stateroom roomie, Valerie McCaskill.  Valerie is a full time NOAA employee, as she holds the position as Chief Steward.  NOAA Ship Oregon II would not function daily if her position did not exist.

Valerie is from Naples, FL and attended the Art Institute of Atlanta where she studied culinary arts. She has been with NOAA for three years, and also has a cousin that works on a different NOAA vessel.  She stated that she is “responsible for the morale of the ship”.  Her daily duties include making sure everyone has fresh linens, grocery shopping while on shore, preparing all meals, and she even takes special meal request from her fellow crew members.

Her position on NOAA Ship Oregon II is crucial for all to run smoothly while out at sea.  Valerie truly is the heart and Mom of the ship.  She is constantly making sure all crew members are fed and remain steady emotionally.  It takes a special person to hold down the ship and Valerie does just that, while leaving behind her 9 year old son, Kain, for 8 months out the year.  She is also forced to get creative in the kitchen, as there is no stove.  All food is prepared on a grill, in the oven, or in a kettle.

As I am sitting here with Valerie writing this piece of my blog, she rushes out the door because we just heard dishes fall in the kitchen.  She takes care of all the little things aboard the ship, and most expeditions would not be successful without crew members like Valerie.

Personal Log: 

Today I went or 5 mile walk/run to explore the area around the port.  I have always been fascinated by lighthouses, and I was fortunate to come across the Round Island Lighthouse.  The original Round Island Lighthouse was built on Round Island in 1833, but it was relocated and renovated due to damage from Hurricane George in the 90’s.  The lighthouse now sits inland on the western gateway into Pascagoula, Mississippi.

Round Island Lighthouse

We left the port in Pascagoula, Mississippi around 1400.  I made sure I put on my sea sickness patch last night to give the medicine time to get in my system.  I woke up with one dilated eye on the side that I placed the patch.  I much rather have a funny looking eye than get nauseous.

Did You Know?:

There are numerous oil rigs throughout the Gulf of Mexico.  Many bird species that are migrating across the Gulf will stop to rest on the oil rigs.  Unfortunately, most of these birds will not continue on and they will end up dying of exhaustion and dehydration.  A possible reason for the birds interrupting their flight is a change in the wind pattern.  If they are unable to cruise in the jet stream they will be forced to expend more energy to get where they are going.  Sometimes they don’t have that extra energy to go against the wind and will stop their flight on an oil rig.

 

Animals Seen Today:

Mission: Long Line Shark/ Red Snapper survey Leg 1

Geographic Area: Southeastern U.S. coast

Date: August 29, 2018

 

Scientific Journal

Shark On!” was the shout from the first person that sees a shark hooked to the long line that was being hauled up from the floor of the ocean. I heard this phrase often during the first leg of the long line Red Snapper/ shark survey on the NOAA ship Oregon II. We began fishing in the Northwest Atlantic Ocean, off the coast of West Palm Beach, Florida. We traveled north to Cape Hatteras, North Carolina, and back south to Port Canaveral over 12 days this summer.

During our long line deployments each day, we were able to catch, measure, tag and photograph many sharks, before returning them to the ocean quickly and safely. During these surveys, we caught the species of sharks listed below, in addition to other interesting fish from the ocean.  This blog has scientific information about each shark, and photographs taken by myself and other scientists on board the Oregon II. The following information on sharks, in addition to scientific data about hundreds of other marine wildlife can be found online at the NOAA Fisheries site: http://fisheries.noaa.gov.

Great Hammerhead Shark-  Sphyrna mokarran  Hammerhead sharks are recognized by their long, strange hammer-like heads which are called cephalofoils. Great hammerheads are the largest species of hammerheads, and can grow to a length of 20 feet. The great hammerhead can be distinguished from other hammerheads as they have a much taller dorsal fin than other hammerheads.

Great hammerhead
Great Hammerhead in cradle for data collection and return to sea.

When moving through the ocean, they swing their broad heads from side to side and this motion provides them a much wider field of vision than other sharks. It provides them an all around view of their environment as their eyes are far apart at either end of the long hammers. They have only two small blind spots, in front of the snout, and behind the cephalofoil. Their wide heads also have many tiny pores, called ampullae of Lorenzini. They can sense tiny electric currents generated by fish or other prey in distress from far distances.

 

The great hammerhead are found in tropical and temperate waters worldwide, and inhabiting coastal areas in and around the continental shelf. They usually are solitary swimmers, and they eat prey ranging from crustaceans and squid, to a variety of bony fish, smaller sharks and stingrays. The great hammerhead can bear litters of up to 55 pups every two years.

Nurse Shark- Ginglymostoma cirratum Nurse sharks are bottom dwellers. They spend their life in shallow water, near the sandy bottom, and their orangish- pinkish color and rough skin helps them camouflage them. At night they come out to hunt. Nurse sharks have short, serrated teeth that can eat through crustaceans such as crabs, urchins, shrimp, and lobsters. They also eat fish, squid, and stingrays. They have two feelers, or barbels, which hang from either side of their mouth. They use their barbels to search for prey in the sand. Their average adult size is 7.5- 9 feet in length and they weigh between 160-230 lbs. Adult females reach a larger size than the males at 7- 8.5 feet long and can weigh from 200-267 lbs.

Nurse Shark
Nurse Shark- Ginglymostoma cirratum

Nurse sharks are common in the coastal tropical waters of the Atlantic and also in the eastern Pacific Ocean. This species is locally very common in shallow waters throughout the Caribbean, south Florida to the Florida Keys. Large juveniles and adults are usually found around deeper reefs and rocky areas at depths of 10-250 feet during the daytime and migrate into shallower waters of less than 70 feet deep after dark.

 

Juveniles up to 6 feet are generally found around shallow coral reefs, grass flats or mangrove islands in shallow water. They often lie in groups of forty on the ocean floor or under rock ledges. Nurse sharks show a preference for a certain resting site, and will repeatedly go back to to the same caves for shelter or rest after leaving the area to feed.

Tiger Shark- Galeocerdo cuvier  Adult Tiger sharks average between 10 -14 feet in length and weigh up to 1,400 lbs. The largest sharks can grow to 20 feet and weigh nearly 2,000 lbs. They mature between 5 and 10 years, and their life span is 30 years or more. Tiger sharks are named for the brown stripes and patches they have on their sides when they are young. As they get older, they stripes eventually fade away.

 

They will eat almost anything they come across, and have been referred to as the “garbage cans of the sea”. Their habitat ranges from shallow coastal waters when they are young, to deep waters over 1,500 feet deep. They swim in shallow waters to hunt lobster, squid, fish, sea turtles, birds, and smaller sharks.

They migrate with the seasons to follow prey and to give birth to young. They swim in cool waters in the summer, and in fall and winter they migrate to warm tropical waters. Their young grow in eggs inside the mother’s body and after 13 months the sharks hatch. The mother gives birth to a litter of 10 – 80 pups. Their current status is currently Near Threatened.

Sharpnose Shark- Rhizoprionodon terraenovae Atlantic sharpnose sharks are small for sharks and have a streamlined body, and get their name from their long, pointy snout. They are several different shades of gray and have a white underside.  Atlantic sharpnose sharks can grow to up to 32 inches in length. Atlantic sharpnose sharks have been observed to live up to 18 years. Females mature at around 2 years old in the Atlantic when they reach approximately 24 inches in length. Atlantic sharpnose sharks are commonly found in the western Atlantic from New Brunswick, Canada, right through the Gulf of Mexico. They are commonly caught in U.S. coastal waters from Virginia around to Texas.

Sharpnose shark

Atlantic sharpnose sharks eat small fish, including menhaden, eels, silversides, wrasses, jacks, toadfish, and filefish. The lower and upper jaws of an Atlantic sharpnose shark have 24 or 25 rows of triangular teeth. Atlantic sharpnose sharks mate annually between mid-May and mid-July in inshore waters, and after mating, they migrate offshore to deeper waters.  They also eat worms, shrimp, crabs, and mollusks.

 

Sandbar Shark- Carcharhinus plumbeus.  The most distinctive feature of this stocky, grey shark is its huge pectoral fins, and long dorsal fin that increases its stability while swimming. Females can grow between 6 – 8.5 feet, and males grow up to 6ft. Its body color can vary from a blue to a light brown grey with a pale white underside. The sandbar shark lives in coastal waters, living in water that is 20 to 200 feet deep. Rarely is its large dorsal fin seen above the water’s surface, as the sandbars prefer to remain near the bottom. It commonly lives in harbors, lagoons, muddy and sandy bays, and river mouths, but never moves into freshwater. The sandbar shark lives in warm and tropical waters in various parts of the world including in the Western Atlantic, from Massachusetts down to southern Brazil.

Sandbar shark

The sandbar shark spends the majority of its time near the ocean floor, where it looks continuously for prey, such as small fish, mollusks, and various crustaceans. Their main diet consists largely of fish. Sandbar sharks give birth to between 1 and 14 pups in each litter. The size of the litter depends on the size of the mother, with large females giving birth to larger litters. Pregnancy is estimated to last between 8- 12 months. Females move near shore to shallow nursery areas to give birth. The females leave coastal areas after giving birth, while the young remain in the nursery grounds until winter, when they move into warmer and deeper water.

 

 

Fun Fact- Remoras, or shark suckers, live in tropical oceans around the world. They have a rigid oval- shaped sucker pad on top of their head that it uses to attach itself to sharks and rays. It is symbiotic relationship where both animals gain something from their temporary union. Remoras mouths are at the top front of the body so while attached to a shark’s body, they do their host a favor by nibbling off skin parasites. They can also eat scraps of leftover food the shark leaves behind while they also enjoy a free ride. The shark gains a day at the spa for a body scrub, and can rid itself of parasites in a way it couldn’t have before!

Personal Journal

It was certainly an unforgettable experience being able to work with the scientific and fishing team for this shark survey. The opportunity to see and handle these sharks up close for two weeks has informed me of so many interesting things about these wonderful and vital members of the ocean.  I can now take this information and share it first hand with students in my classroom, and members of my community. I also want to work to bring a positive awareness to these vital members of the ocean food web so they can thrive well into the future. As an artist, this trip has been invaluable for me, as now I’ve seen the how colorful and varied sharks are and other various anatomy details you just can’t see in books or television. This new awareness will help to make my future paintings more accurate than before.

Science and Technology Log

Before getting into the technology that allows the scientific work to be completed, it’s important to mention the science and technology that make daily life on the ship safer, easier, and more convenient. Electricity powers everything from the powerful deck lights used for working at night to the vital navigation equipment on the bridge (main control and navigation center). Whether it makes things safer or more efficient, the work we’re doing would not be possible without power. Just in case, several digital devices have an analog (non-electronic) counterpart as a back-up, particularly those used for navigation, such as the magnetic compass.

To keep things cool, large freezers are used for storing bait, preserving scientific samples, and even storing ice cream (no chumsicles for dessert—they’re not all stored in the same freezer!). After one particularly sweltering shift, I was able to cool off with some frozen coffee milk (I improvised with cold coffee, ice cream, and milk). More importantly, without the freezers, the scientific samples we’re collecting wouldn’t last long enough to be studied further back at the lab on land.

Electricity also makes life at sea more convenient, comfortable, and even entertaining. We have access to many of the same devices, conveniences, and appliances we have at home: laundry machines, warm showers, air conditioning, home cooked meals, a coffee maker, TVs, computers with Wi-Fi, and special phones that allow calls to and from sea. A large collection of current movies is available in the lounge. During my downtime, I’ve been writing, exploring, enjoying the water, and learning more about the various NOAA careers on board.

To use my computer, I first needed to meet with Roy Toliver, Chief Electronics Technician, and connect to the ship’s Wi-Fi. While meeting with him, I asked about some of the devices I’d seen up on the flying bridge, the top deck of the ship. The modern conveniences on board are connected to several antennae, and Roy explained that I was looking at important navigation and communication equipment such as the ship’s GPS (Global Positioning System), radar, satellite, and weather instrumentation.

I was also intrigued by the net-like item (called a Day Shape) that communicates to other ships that we are deploying fishing equipment. This lets nearby ships know that the Oregon II has restricted maneuverability when the gear is in the water. At night, lights are used to communicate to other ships. Communication is crucial for safety at sea.

When I stopped by, Roy had just finished replacing some oxygen sensors for the CTD (that stands for Conductivity, Temperature, and Depth). For more information about CTDs click here: https://oceanexplorer.noaa.gov/facts/ctd.html

Without accurate sensors, it’s very difficult for the scientists to get the data they need. If the sensors are not working or calibrated correctly, the information collected could be inaccurate or not register at all. The combination of salt water and electronics poses many interesting problems and solutions. I noticed that several electronic devices, such as computers and cameras, are built for outdoor use or housed in durable plastic cases.

On this particular day, the ship sailed closer to an algal bloom (a large collection of tiny organisms in the water) responsible for red tide. Red tide can produce harmful toxins, and the most visible effect was the presence of dead fish drifting by. As I moved throughout the ship, the red tide was a red hot topic of conversation among both the scientists and the deck department. Everyone seemed to be discussing it. One scientist explained that dissolved oxygen levels in the Gulf of Mexico can vary based on temperature and depth, with average readings being higher than about 5 milligrams per milliliter. The algal bloom seemed to impact the readings by depleting the oxygen level, and I was able to see how that algal bloom registered and affected the dissolved oxygen readings on the electronics Roy was working on. It was fascinating to witness a real life example of cause and effect. For more information about red tide in Florida, click here: https://oceanservice.noaa.gov/news/redtide-florida/

Personal Log

Preparing and packing for my time on the Oregon II reminded me of The Oregon Trail video game. How to pack for a lengthy journey to the unfamiliar and unknown?

A video game screenshot
I had a hard time finding bib overalls and deck boots at the general store.

I didn’t want to run out of toiletries or over pack, so before leaving home, I tracked how many uses I could get out of a travel-sized tube of toothpaste, shampoo bottle, and bar of soap, and that helped me to ration out how much to bring for fifteen days (with a few extras, just in case). The scientists and crew of the Oregon II also have to plan, prepare, and pack all of their food, clothing, supplies, tools, and equipment carefully. Unlike The Oregon Trail game, I didn’t need oxen for my journey, but I needed some special gear: deck boots, foul weather gear (rain jacket with a hood and bib overalls), polarized sunglasses (to protect my eyes by reducing the sun’s glare on the water), lots of potent sunscreen, and other items to make my time at sea safe and comfortable.

I was able to anticipate what I might need to make this a more efficient, comfortable experience, and my maritime instincts were accurate. Mesh packing cubes and small plastic baskets help to organize my drawers and shower items, making it easier to find things quickly in an unfamiliar setting.

berths on ship show blue privacy curtains
This is where we sleep in the stateroom. The blue curtains can be closed to darken the room when sleeping during the day. On the left is a sink.

My own shark cradle
Reading and dreaming about sharks!

Dirt, guts, slime, and grime are part of the job. A bar of scrubby lemon soap takes off any leftover sunscreen, grime, or oceanic odors that leaked through my gloves. Little things like that make ship life pleasant. Not worrying about how I look is freeing, and I enjoy moving about the ship, being physically active. It reminds me of the summers I spent as a camp counselor working in the woods. The grubbier and more worn out I was, the more fun we were having.

The NOAA Corps is a uniformed service, so the officers wear their uniforms while on duty. For everyone else, old clothes are the uniform around here because the work is often messy, dirty, and sweaty. With tiny holes, frayed seams, mystery stains, cutoff sleeves, and nautical imagery, I am intrigued by the faded t-shirts from long-ago surveys and previous sailing adventures. Some of the shirts date back several years. The well-worn, faded fabric reveals the owner’s experience at sea and history with the ship. The shirts almost seem to have sea stories to tell of their own.

Sunset over water showing orange, pink, and blue hues.
As we sail, the view is always changing and always interesting!

Being at sea is a very natural feeling for me, and I haven’t experienced any seasickness. One thing I didn’t fully expect: being cold at night. The inside of the ship is air-conditioned, which provides refreshing relief from the scorching sun outside. I expected cooler temperatures at night, so I brought some lightweight sweatshirts and an extra wool blanket from home. On my first night, I didn’t realize that I could control the temperature in my stateroom, so I shivered all night long.

A folded grey hooded sweatshirt
It’s heavy, tough, and grey, but it’s not a shark!

My preparing and packing didn’t end once I embarked (got on) on the ship. Every day, I have to think ahead, plan, and make sure I have everything I need before I start my day. This may seem like the least interesting aspect of my day, but it was the biggest adjustment at first.

To put yourself in my shoes (well, my deck boots), imagine this:

Get a backpack. Transport yourself to completely new and unfamiliar surroundings. Try to adapt to strange new routines and procedures. Prepare to spend the next 12+ hours working, learning, exploring, and conducting daily routines, such as eating meals. Fill your backpack with anything you might possibly need or want for those twelve hours. Plan for the outdoor heat and the indoor chill, as well as rain. If you forgot something, you can’t just go back to your room or run to the store to get it because

  1. Your roommate is sleeping while you’re working (and vice versa), so you need to be quiet and respectful of their sleep schedule. That means you need to gather anything you may need for the day (or night, if you’re assigned to the night watch), and bring it with you. No going back into the room while your roommate is getting some much-needed rest.
  2. Land is not in sight, so everything you need must be on the ship. Going to the store is not an option.

Just some of the items in my backpack: sunscreen, sunglasses, a hat, sweatshirt, a water bottle, my camera, my phone, my computer, chargers for my electronics, an extra shirt, extra socks, snacks, etc.

I am assigned to the day watch, so my work shift is from noon-midnight. During those hours, I am a member of the science team. While on the day watch, the five of us rotate roles and responsibilities, and we work closely with the deck crew to complete our tasks. The deck department is responsible for rigging and handling the heavier equipment needed for fishing and sampling the water: the monofilament (thick, strong fishing line made from plastic), cranes and winches for lifting the CTD, and the cradle used for safely bringing up larger, heavier sharks. In addition to keeping the ship running smoothly and safely, they also deploy and retrieve the longline gear.

A pulley in front of water
Pulleys, winches, and cranes are found throughout the boat.

Another adjustment has been learning the routines, procedures, and equipment. For the first week, it’s been a daily game of What-Am-I-Looking-At? as I try to decipher and comprehend the various monitors displayed throughout the ship. I follow this with a regular round of Now-What-Did-I-Forget? as I attempt to finesse my daily hygiene routine. The showers and bathroom (on a ship, it’s called the head) are down the hall from my shared stateroom, and so far, I’ve managed to forget my socks (day one), towel (day two), and an entire change of clothes (day four). With the unfamiliar setting and routine, it’s easy to forget something, and I’m often showering very late at night after a long day of work.

Showers and changing stalls on ship
I’m more than ready to cool off and clean up after my shift.

One thing I never forget? Water. I am surrounded by glittering, glistening water or pitch-black water; water that churns and swells and soothingly rocks the ship. Swirling water that sometimes looks like ink or teal or indigo or navy, depending on the conditions and time of day.

Another thing I’ll never forget? This experience.

A water bottle in the sun
In case I forget, the heat of the sun reminds me to drink water all day long.

Did You Know?

The Gulf of Mexico is home to five species, or types, or sea turtles: Leatherback, Loggerhead, Green, Hawksbill, and Kemp’s Ridley.

Recommended Reading

Many of my students have never seen or experienced the ocean. To make the ocean more relevant and relatable to their environment, I recommend the picture book Skyfishing written by Gideon Sterer and illustrated by Poly Bernatene. A young girl’s grandfather moves to the city and notices there’s nowhere to fish. She and her grandfather imagine fishing from their high-rise apartment fire escape. The “fish” they catch are inspired by the vibrant ecosystem around them: the citizens and bustling activity in an urban environment. The catch of the day: “Flying Litterfish,” “Laundry Eels,” a “Constructionfish,” and many others, all inspired by the sights and sounds of the busy city around them.

The book could be used to make abstract, geographically far away concepts, such as coral ecosystems, more relatable for students in urban, suburban, and rural settings, or as a way for students in rural settings to learn more about urban communities. The young girl’s observations and imagination could spark a discussion about how prominent traits influence species’ common names, identification, and scientific naming conventions.

Science and Technology Log

Longline fishing is a technique that consists of one main fishing line with many baited hooks that come of that line on shorter lines, (like branches off a tree) attached at various distances. Long lines are used in both coastal areas and the open ocean and are often placed to target specific species. If the long line is suspended in the top or mid depth water, it is called pelagic longline fishing. If it is on or near the ocean floor by weighting it down to the sea floor, it is called bottom longline fishing. A high-flyer buoy is placed at either end to mark the position of the line in the water so boats can see it while submerged, and so it can be found when it needs to be retrieved. Weights are placed on each end and the middle of the line to hold the line down to a specified depth.

On board NOAA Ship Oregon II, the mission is a red snapper/shark longline fishing survey in the Gulf of Mexico and the Western North Atlantic coast. I was on the first of four legs of the survey that left Pascagoula, Mississippi, rounded the bottom of Florida and stopped for 44 stations between West Palm Beach FL, up to Cape Hatteras, NC, and back down to Port Canaveral, FL. NOAA’s mission is to research current shark and snapper populations in specific areas as determined by NOAA shark scientists and related state Fishery Departments.

The Oregon II has a large spool of 3mm monofilament fishing line on deck. For our survey, we used a line that was one mile long, and had 100 baited hooks approximately 50 feet apart. The hooks are attached to the line by gangions. Gangions are 12 foot long monofilament lines with a hook on one end and a manual fastener at the other end that can be taken on and off each time the line is deployed. All 100 hooks on the gangions are baited with Atlantic mackerel.

To deploy the line into the water, it takes a team of 6 people. The first person strings the line from the spool and through various pulleys along the length of the ship moving toward the back of the boat before tying it to the high flyer buoy and returning to the spool control to deploy the mile long line into the water. A team of two works to attach a specific number tag onto each gangion, and then to retrieve the 12 foot long gangion from a barrel. The numbered, baited, gangions are handed one by one to the next team member who attaches the gangion of the main long line every 60 feet as the line descends into the water. This crewman also places three weights on the line to hold it onto the ocean floor, one at each end, and one in the middle. When all hooks are deployed, the line is cut from the spool and the high-flyer buoy is attached to mark the end of the line in the water.

The last member of the science team is at a computer station on deck and they are in charge of inputting data into the computer. Each time a buoy, weight, or gangion goes into the water, a specific button is pushed to mark the items place in the water. This is done so when a shark comes up on a numbered hook, NOAA scientists know exactly the latitude, longitude and depth of where that specific shark was caught. Scientists upload this important data immediately to NOAA servers for later use so they can assess average populations in specific areas, among many other data points.

Input
Each time a gangion, weight, or high-flyer buoy is deployed, its location is input in the computer.

The bait stays down on the ocean floor for about an hour before the boat returns to retrieve it. The retrieval process is similar to deploying the line except that it takes longer to bring it in, as there are now some fish and sharks attached to the hooks. If the hooks are empty, the number is taken off the line, and the gangion is placed back in the barrel until the next station. If there is a shark or fish on the line, it is pulled onto the deck and data is collected before the shark is safely placed back into the water. The first step is unhooking the fish, before it is measured. The shark is measured from the tip of the nose to various parts of the body to determine the size in those areas. The gender of the shark is also determined, as well as the maturity. Finally, the shark is weighed on a scale and most are tagged before being photographed and released. The process only takes about two minutes to safely ensure the shark survives. The data is recorded on a data log, and after the retrieval, the data is input into a database.

Removing Gangions
Gangions are taken off the long line, de-baited, de-numbered and put back in barrel.

 

Personal Log

Before coming on the Oregon II, I knew only about the fishing process on a larger scale from what I’d read about, or seen on television. I was slightly intimidated that without experience, I’d likely be slowing down the experienced team of professionals from their difficult job. As we headed out to sea, I found out it would take a few days before we reached our first station and that gave me time to get to know the crew, which was very valuable. There are two crews, each work 12 hours a day, so fishing was happening around the clock. I was able to listen to their advice and explanation of the techniques used in the long line process, and also some fantastic stories about their lives and families. Their patience with me and the other volunteers during those first few stations gave us time to get up to their speed, and from then out it was like clockwork. It was certainly hard to work outside all day, but the passion, skill, and humor of the crew made it quite fun work each day and night. It was impressive and amazing to see how this efficient process is used to help NOAA scientists and fishermen collect data from vast areas of the ocean for two weeks. I am proud to say I helped a great team to get information that can help us understand how to help populations of sharks and fish for long into the future.

Introduction:

According to Greek mythology, coral first originated in the Red Sea.  The story has been told that after Perseus, a Greek hero, beheaded Medusa, he set her head down on a clump of seaweed to wash his hands.  The blood from Medusa’s head soaked into the seaweed forming what we know today as coral. Ironically, coral polyps contain tentacles reminiscent of the snakes consuming Medusa’s head.  I am lucky enough to have my own piece of Coral.  Three and half years ago my husband and I had our first child and named her Coral.  The only aspect of Coral’s life that is even a slight resemblance of Medusa is her crazy curly hair!   As we know, coral in the ocean is a beautiful animal that houses thousands of marine organisms.  Similarly, my daughter has an enormous heart for living creatures, and her curiosity for the natural world inspires me every day.

We also have a son named Kai.  In Hawaiian, Kai means ‘the sea’, and in Japanese one of its meanings is ‘ocean.’  I love watching Kai grow daily, and learn new ways to survive having Coral as his big sister. Although I will have to say a heartbreaking temporary goodbye to Coral and Kai, I will be embarking on a journey of a lifetime.  My expedition starts in Pascagoula, Mississippi on August 31st aboard NOAA Ship Oregon II, where I will participate in a shark/red snapper longline survey in the Gulf of Mexico.

I have always been fascinated by the water.  Growing up near Lake Michigan, family trips consisted of going to the beach and searching for “seashells” along the shore.  My passion for the ocean also began during my childhood, which was sparked by my interest in turtles.  I was a captivated 15 year old when I saw a sea turtle for the first time as I snorkeled on a patch reef near Key Largo.  The speed at which the juvenile loggerhead sea turtle (Caretta caretta) glided through the water was astonishing.  I was fortunate to capture a few pictures of the critically threatened animal as it sped by, which was then painted onto a beautiful canvas by a dear friend of mine.

That moment inspired and motivated me to study the ocean, and I went on to obtain a Bachelor of Science degree in marine biology from Eckerd College in St. Petersburg, FL. During my time at Eckerd College, I had the opportunity to intern for the University of Florida’s Cape San Blas sea turtle surveying program.  It was during this internship that I had my first indirect encounter with a shark.  Well, not really an actual shark, but Yolanda, a nesting loggerhead sea turtle.  I first met Yolanda in the summer of 2004.  She was a healthy adult sea turtle and a regular nester on Cape San Blas, as her tag had been recorded since the 90’s on the exact same beach that I first saw her.  What I have failed to mention is that she had an enormous shark bite through her carapace and plastron just above her right rear flipper.  Remarkably, the shark missed all major organs and the bite had healed completely into a perfect mandible mold.  Besides Yolanda’s shark bite, and small reef sharks that I’ve seen diving, I never thought I would experience an up close meeting with a shark.  For two weeks straight I will be assisting NOAA scientists with catching and tagging a variety of different species of sharks.

I stumbled upon on this endangered nesting leatherback sea turtle (Dermochelys coriaceaone) one morning on Juno Beach, FL.

I am most excited for the impact that the Teacher at Sea adventure will have on me personally, and as an educator at Crown Point High School.  I hope to take what I learn while aboard NOAA Ship Oregon II and aide my students in better hypothesis-generation, experimental testing, and presentation skills to cultivate major changes in their approach to scientific research.  Ultimately, I can’t wait to share my experience with the Crown Point community, and continue to create an atmosphere where kids are excited about learning science!

Science and Technology Log

For the first few days, we steamed, or traveled, to our first station. Each station is a research location where several activities will take place:

  1. Preparing and setting out the longline gear.
  2. Letting the line soak (fish on the bottom) for one hour while other tasks are performed.
  3. Deploying a CTD (Conductivity Temperature Salinity) to collect samples and information about the water.
  4. Hauling back the longline gear.
  5. Recording data from the longline set and haulback.
  6. Collecting measurements and samples from anything caught on the longline.
  7. Depending on what is caught: attaching tags and releasing the animal back into the water (sharks) or collecting requested samples for further study (bony fish).

This is a very simplified summary of the various activities, and I’ll explore some of the steps in further detail in other posts.

During these operations and in between tasks, scientists and crew are very busy. As I watched and participated, the highly organized, well-coordinated flurry of activity on deck was an incredible demonstration of verbs (action words): clean, rinse, prepare, gather, tie, hook, set, haul, calibrate, operate, hoist, deploy, retrieve, cut, measure, weigh, tag, count, record, release, communicate

Last night, I witnessed and participated in my first longline station. I baited 100 hooks with mackerel. I recorded set and haulback data on the computer as the gear was deployed (set) and hauled back in (haulback). I attached 100 numbered tags to the longline gangions (attached to the hooks). I recorded measurements and other data about SHARKS!

We caught, measured, sampled, tagged, and released four sharks last night: a silky, smooth-hound, sandbar, and tiger shark! I’ve never seen any of these species, or types, in person. Seeing the first shark burst onto the deck was a moment I’ll remember for the rest of my life!

Sometimes, we didn’t catch any fish, but we did bring up a small piece of coral, brittle sea stars, and a crinoid. All three are marine animals, so I was excited to see them in person.

In between stations, there was some downtime to prepare for the next one. One of my favorite moments was watching the GoPro camera footage from the CTD. A camera is attached to the device as it sinks down through the depths to the bottom and back up to the surface again. The camera allowed me to visually ‘dive along’ as it collected water samples and data about the water temperature, salinity, pressure, and other information. Even though I watch ocean documentaries frequently and am used to seeing underwater footage on a screen, this was extremely exciting because the intriguing ecosystem on the screen was just below my feet!

Personal Log

Perhaps it is sea lore and superstition, but so far, the journey has been peppered with fortuitous omens. One of my ocean-loving former students and her Disney-bound family just happened to be on my flight to Orlando. Yes, it’s a small world after all. Her work samples were featured in our published case study, reminding me of the importance and impact of ocean literacy education. Very early the next morning, NASA’s promising Parker Solar Probe thunderously left the Sunshine State, hurtling toward the sun. New York’s state motto: Excelsior. Later that morning, a rainbow appeared shortly before the Oregon II left Port Canaveral. Although an old weather proverb states: “rainbow in the morning gives you fair warning,” we’ve had very pleasant weather, and I chose to interpret it as a reassuring sign. Sailing on the Oregon II as a Teacher at Sea is certainly my pot of gold at the end of the rainbow.

 

According to seafaring superstition, women on board, whistling, and bananas are supposed to be bad luck on a boat. On the Oregon II, folks do not seem to put much stock into these old beliefs since I’ve encountered all three aboard the ship and still feel very lucky to be here.

The rest of the fruit seems to think that bananas are bad luck…the crew doesn’t!

In another small-world coincidence, two of the volunteers on the Second Leg of the Shark/Red Snapper Longline Survey recently graduated from SUNY Potsdam, my undergrad alma mater. What drew us from the North Country of New York to Southern waters? A collective love of sharks.

These small-world coincidences seemed indicate that I was on the right path. Out on the ocean, however, the watery world seems anything but small. The blue vastness and unseen depths fill me with excitement and curiosity, and I cannot wait to learn more. For the next two weeks, the Oregon II will be my floating classroom. Instead of teaching, I am here to learn.

As a fourth generation teacher, education is in my blood. One great-grandmother taught in a one-room schoolhouse in 1894. My other great-grandmother was also a teacher and a Potsdam alumna (Class of 1892). As we traverse the Atlantic Ocean, I wonder what my academic ancestors would think of their great-granddaughter following in their footsteps…whilst studying sharks and snapper at sea. Salt water equally runs through my veins.

As we steamed, or traveled, to our first station (research location), I wondered about the unfamiliar waters and equipment around me. Before I could indulge my questions about marine life, however, I first needed to focus on the mundane: daily life at sea. In many ways, I was reminded of the first day at a new school. It was junior high all over again, minus the braces and bad bangs. At first, those long-forgotten new school worries resurfaced: What if I get lost? Where is my locker (or, in this case, my stateroom)? What if I forget my schedule? What if I have to sit by myself at lunch? To combat these thoughts, I draw upon a variety of previous travel and life experiences: studying abroad, backpacking, camping, meeting new friends, volunteering, working with a marine science colleague, and sailing on other vessels. Combined, those experiences provided me with the skills to successfully navigate this one.

I’ve spent the first few days getting acquainted with the layout, personnel, safety rules, and routines of the Oregon II. My students wondered about some of the same aspects of life at sea.

Where do I sleep on the ship?

The staterooms remind me of a floating college dorm, only much quieter. I’m sharing a small stateroom with Kristin Hannan, a scientist. We are on opposite work shifts, so one of us is sleeping while the other is working. I am assigned to the day shift (noon to midnight) while she is assigned to the night shift (midnight to noon). Inside the stateroom, we have berths (similar to bunk beds), a sink, and large metal storage cabinets that are used like a closet or dresser. Space is limited on the ship, so it must be used efficiently and sometimes creatively.

Do you know anyone else on the ship?

No, but I’m meeting lots of new people. They have been welcoming, offering interesting information and helpful reminders and pointers. Those first-day-of-school jitters are fading quickly. I didn’t get lost, but I got a bit turned around at first, trying to figure out which deck I needed for the galley (like the ship’s cafeteria), where we eat our meals. And I only had to eat lunch by myself once. On the first day at sea, I made a PB & J sandwich. Eating that, I felt like a kid again (only without my lunchbox), but it was nice to be at a point in my life where I’m confident enough to be all by myself and feel a bit out of place. That’s how you learn and grow. Everything is new to me right now, but with time, it’ll start to make sense. Pretty soon, the equipment and unfamiliar routines will start to feel more familiar. Hopefully, the sharks will like me.

Did You Know?

The Gulf of Mexico is home to approximately 200 orcas (scientific name: Orcinus orca, also known as killer whales).

Mission: Long Line Shark/ Red Snapper survey Leg 1

Geographic Area: 30 19’ 54’’ N, 81 39’ 20’’ W, 10 nautical miles NE of Jacksonville, Florida

Date: August 9, 2018

Weather Data from Bridge: Wind speed 11 knots, Air Temp: 30c, Visibility 10 nautical miles, Wave height 3 ft.

Science and Technology Log

Sharks have senses similar to humans that help them interact with their environment. They use them in a specific order and rely on each one to get them closer for navigational reasons, and to find any food sources in the area around them. The largest part of the shark’s brain is devoted to their strong sense of smell, so we’ll start there.

Smell– Sharks first rely on their strong sense of smell to detect potential food sources and other movement around them from a great distance. Odor travels into the nostrils on either side of the underside of the snout. As the water passes through the olfactory tissue inside the nostrils, the shark can sense or taste what the odor is, and depending which nostril it goes into, which direction it’s coming from. It is said that sharks can smell one drop of blood in a billion parts of water from up to several hundred meters away.

Sharks can also sense electrical currents in animals from long distances in several ways. Sharks have many electro sensitive holes along the snout and jaw called the Ampullae of Lorenzini. These holes detect weak electrical fields generated by the muscles in all living things. They work to help sharks feel the slightest movement in the water and sand and direct them to it from hundreds of meters away. This system can also help them detect the magnetic field of the earth and sharks use it to navigate as well.

Hearing– Sharks also heavily use their sense of smell to initially locate objects in the water. There are small interior holes behind their eyes that can sense vibrations up to 200 yards away. Sound waves travel much further in water than in the air allowing them to hear a great distance away in all directions. They also use their lateral lines, which are a fluid filled canal that runs down both sides of the body. It contains tiny pores with microscopic hairs inside that can detect changes in water pressure and the movement and direction of objects around them.

Sight– Once sharks get close enough to see an object, their eyes take over. Their eyes are placed on either side of their head to provide an excellent range of vision. They are adapted to low light environments, and are roughly ten times more sensitive to light than human eyes. Most sharks see in color and can dilate their pupils to adapt to hunting at different times of day. Some sharks have upper and lower eyelids that do not move. Some sharks have a third eyelid called a nictitating membrane, which is an eyelid that comes up from the bottom of the eye to protect it when the shark is feeding or in other dangerous situations. Other sharks without the membrane can roll their eyes back into their head to protect them from injury.

Touch– After using the previous senses, sometimes a shark will swim up and bump into an object to obtain some tactile information. They will then decide whether it is food to eat and attack, or possibly another shark of the opposite gender, so they can mate.

Taste– Sharks are most famous for their impressive teeth. Most people are not aware that sharks do not have bones, only cartilage (like our nose and ears) that make up their skeletal system, including their jaw that holds the teeth. The jaw is only connected to the skull by muscles and ligaments and it can project forward when opening to create a stronger bite force. Surface feeding sharks have sharp teeth to seize and hold prey, while bottom feeding sharks teeth are flatter to crush shellfish and other crustaceans. The teeth are embedded in the gums, not the jaw, and there are many rows of teeth behind the front teeth. It a tooth is damaged or lost, a new one comes from behind to replace it soon after. Some sharks can produce up to 30,000 teeth in their lifetime.

Personal Log

While I had a general knowledge of shark biology before coming on this trip, I’ve learned a great deal about sharks during my Teacher at Sea experience aboard the Oregon II. Seeing, observing, and holding sharks every day has given me first hand knowledge that has aided my understanding of these great creatures. The pictures you see of the sharks in this post were taken by me during our research at sea. I could now see evidence of all their features up close and I could ask questions to the fishermen and scientists onboard to add to the things I read from books. As an artist, I can now draw and paint these beautiful creatures more accurately based on my reference photos and first hand observations for the deck. It was amazing to see that sharks are many different colors and not just different shades of grey and white you see in most print photographs. I highly encourage everyone that has an interest in animals or specific areas of nature to get out there and observe the animals and places firsthand. I guarantee the experience will inspire you, and everyone you tell of the many great things to be found in the outdoors.

Normally you wouldn’t hear the words shark and cradle in the same sentence, but in our case, the cradle is one of the most important pieces of equipment we use each day. Our mission on the Oregon II is to survey sharks to provide data for further study by NOAA scientists. We use the long line fishing method where 100 hooks are put out on a mile long line for about an hour, and then slowly hauled up by a large mechanical reel. If a shark is generally three feet and weighs 30lbs or less, it is handled by hand to carefully unhook, measure and throw back. If the shark is much larger and cannot be managed safely by hand, it is then held on the line by the ships rail until it can be lifted on deck by the cradle to be quickly measured, tagged, and put back into the ocean.

The shark cradle
The shark cradle

The shark cradle is 10 ft. long, with a bed width of roughly 4 feet. It is made from thick aluminum tubing and strong synthetic netting to provide the bed for the shark to lie on. It is lifted from the ship’s deck by a large crane and lowered over the ships rail into the ocean. The shark is still on the line and is guided by a skilled fisherman into the cradle. The crane operator slowly lifts the cradle out of the water, up to the rail, so work can begin.

A team of 3 highly skilled fishermen quickly begin to safely secure the shark to protect it, and the team of scientists collecting data. They secure the shark at 3 points, the head, body and tail. Then the scientists come in to take 3 measurements of the shark. The precaudal measurement is from the tip of nose to the start of the tail. The fork measurement is from the tip of the nose to the fork of the tail (the place where the top and bottom of the tail meet). Finally there is a total length taken from the tip of the nose to the furthest tip of the tail.
