Conclusion

Wow, it’s hard to believe that my time on the waters of Alaska aboard the Oscar Dyson are over.  It was an experience I will never forget.  I just hope that I can instill in my students the idea that all kinds of things are possible when you follow your interests. 

It has taken me several days to reacclimatize to life on land.  Standing in front of my class, I have caught myself swaying.  It also took several days to readjust my sleep schedule.  (I don’t get rocked to sleep anymore and my hours are completely different.)

There were so many things I will miss and never forget: all of the unique experiences and sights I got to see, starting with my side trip to Barrow and swimming in the Arctic Ocean before the start of the expedition, getting to explore some of Kodiak before we left port, all of the open sea and species that were part of the random samples, the little coves we snuck into when storms were approaching, getting a “close-up” of the Pavlof volcano, and getting to explore the native land around Dutch Harbor where we were able to watch Salmon spawning and Bald Eagles doing their thing. 

It was also interesting talking to and learning from the ship crew.  There are some interesting stories there about how they got to NOAA and what they have experienced since then.

At the top of the list though would have to be the connections I made with the scientists I spent almost three weeks with.  Being able to go out into the field with them and talking about what they have seen and learned over years of research has really reenergized my love for science in general.  Starting my shift looking forward to seeing what each Bongo station would bring up or what each trawl would bring to the sorting table, made for an expedition that went much too quickly.  It was interesting listening to my fellow scientists comparing how the numbers and ages of pollock caught at the various stations compared to what they had found in the Spring and in previous years. 

airport meal
The science crew all had the chance for one last meal together at the Anchorage airport before parting ways. I am very thankful for being accepted so well and for everything I have learned.

Overall, this has been an experience I will never forget.  I have learned so much about Alaska, the ocean, marine species, global warming, and scientific technology.  My time as a Teacher at Sea aboard the Oscar Dyson is something I will never forget and hope I can pass the excitement and experiences on to my students.

Personal Log

I can’t believe I’ve been back on land for one week already. My 14 days on the NOAA Ship Oscar Dyson flew by. Everyone has asked me how my trip was and I simply state, “epic.” It was by far one of the coolest experiences of my life. I am proud of myself for taking on such an adventure. I hope I inspire my daughters, students, and colleagues to never stop daring, dreaming, and discovering. The trip itself exceeded my highest expectations. I realized how lucky I was to have such warm weather and calm seas. The scientists agreed it was one of calmest expeditions they have ever had in terms of sea conditions. One of the coolest experiences of being a Teacher at Sea was the ability to see every aspect of the vessel. The NOAA Corps officers, the deck crew, and the scientists were so welcoming and friendly. I truly felt at home on board wherever I ventured. By the end of our cruise, our science watch was seamless while conducting the fish surveys. I got the biggest compliment on the last day of our trip when two of the deck crew said they thought I was one of the NOAA scientists the whole time. They both had no idea I was actually a teacher at sea until I mentioned that I was headed back home to teach in Key West.

Just when I thought my adventure was over, I had one of my most memorable moments of the trip. The science team and I had some down time while waiting to board our flight out of Kodiak to Anchorage. We were so thrilled to be back on land that we decided to go on a walk-about around the airport area. We stumbled upon a freshwater river where Pink Salmon were spawning (aka a salmon run). The salmon run is the time when salmon, which have migrated from the ocean, swim to the upper reaches of rivers where they spawn on gravel beds. We stood on the river bank in awe watching hundreds of them wiggle upstream. We also came across fresh bear scat (poop) that was still steaming. It was pretty crazy! Our walk-about was such a random fun ending to an epic adventure.

I am so thankful for this opportunity. It was the trip of a lifetime. It was an honor and a privilege that I will never forget. I will be sharing it with my students for years to come. I am looking forward to attending future NOAA Teacher at Sea Alumni gatherings to meet fellow TAS participants and continuing this amazing experience.

Phew…finally a day to sit back and take a breath! A few days after getting back from sea, I attended our school district’s inservice and am now 2 weeks into the new school year. It is hard to believe how quickly the summer break goes by!

Back in Juneau, the sunny, warm weather has continued, which has also meant no shortage of adventures. Since getting home, friends and I have hiked the Juneau Ridge, fished in Lynn Canal, and hunted on Admiralty Island. It has been a warm welcome home! A group of us are also training for the upcoming Klondike Running Relay from Skagway, AK to Whitehorse, YT. Needless to day, I was VERY happy to have a treadmill and workout equipment on the boat to keep active while at sea.

On the school side of things, I felt lucky to have some time to spend curriculum planning while at sea. It has helped me have a smooth start to the year and give the new 7th graders a great start. I am definitely looking forward to sharing my Teacher at Sea experience with all my new kiddos.

With the return to school, my relaxing days at sea have been replaced with nonstop action in and out of the classroom. Not only does the school year bring teaching science classes, but also an Artful Teaching continuing education course, coaching our middle school cross country team, and planning events for SouthEast Exchange (SEE). SEE is an organization I am a part of that works to connect local professionals, like those I met at sea, with local teachers. Our goal is to bring more real-world and place-based experiences into our classrooms. Through my involvement with SEE, I met and worked with NOAA scientist Ebett Siddon. Along with collaborating together on a unit about Ecosystem Based Fisheries Management for my 7th graders, she also told me about Teachers at Sea!

With that, I would like to say a HUGE thank you to all of the staff at NOAA who help make this program possible. It was a once in a lifetime experience that has helped me better understand the field I am teaching about. I look forward to using what I have learned about studying fish populations and the unique career opportunities at sea with my students. I know they will appreciate my new expertise and see that there always opportunities to keep learning!

Introduction

Hi everyone! I am currently on flight number two of four over the next two days to get me all the way from Key West, Florida to Kodiak, Alaska! Sure beats the 5,516 mile drive it would take me by car! My new home for the next two plus weeks will be aboard the NOAA Ship Oscar Dyson. It is an ultra-quiet fisheries survey vessel built to collect data on fish populations, conduct marine mammal and seabird surveys, and study marine ecosystems. The ship operates primarily in the Bering Sea and Gulf of Alaska.

So what exactly will I be doing these next few weeks at sea? I will be working side by side with world-renowned NOAA scientists during twelve hour shifts (noon to midnight). Our research will focus on collecting data on the Walleye Pollock (also known as Alaskan Pollock) population and other forage fishes in the western Gulf of Alaska. Most of our samples will be collected by midwater trawling (or net fishing). I will be spending many hours in the onboard fish lab working hands-on with scientists to help sort, weigh, measure, sex, and dissect these samples. We will also collect zooplankton and measure environmental variables that potentially affect the ecology of these fishes. We will conduct CTD casts (an instrument used to measure the conductivity, temperature, and pressure of seawater) and take water samples along transects to examine the physical, chemical, and biological oceanography associated with cross-shelf flow.


A Little About Me

How did a little girl who grew up playing in the Georgia woods wind up being a marine science teacher in Key West and now on a plane to Kodiak, Alaska to work as a scientist at sea? I applied for every internship, program, and job I ever dreamed of often times with little to no experience or chance of getting it. I was a wildlife/zoology major at the University of Georgia. However during high school, my parents bought a second home in Key West where I would live during my summers off. I applied and got a job on a snorkel boat at 18 with zero boating experience. After college, I once again applied for a job with the Florida Fish and Wildlife Commission that I was not qualified for in the least. I did not get the job, but at least I went for it regardless of the outcome. So I continued to do odds and ends (often non-paying) internships at MOTE, the Turtle Hospital, and Reef Relief while working to get my 100 ton captain’s license at age 21.

About 6 months after the first FWC interview, the local FWC director called me one day out of the blue and said I now have a job that you are qualified for.

Over the next year at the FWC as a marine biologist, I found that my favorite part of my week was the student outreach program at local schools. I came across a job vacancy for a local elementary science position and thought why not. I had zero teaching experience, a love for science, and the mindset that I can learn to teach as I teach them learn. Eleven years later, I am very proud to be the head of our marine science program at Sugarloaf School. I get the pleasure of teaching my two passions: science and the ocean. I hope to instill a sense of wonder, discovery, and adventure to all my students from kindergarten all the way up through eighth grade.

Last December, I felt the same sense of adventure well up inside of me when I came across the NOAA Teacher at Sea Program. I’m a teacher, a mother of young twins, a part time server, a wife of a firefighter with crazy work hours, and someone who enjoys the comfort of their own bed. All rational thoughts lead to the assumption that this program was out of my league, but it didn’t nor will it ever stop me from continuing to dare, dream and discover. I hope my trip will inspire my students to do the same- to never stop exploring, learning, or continuing to grow in life.

Did You Know?

Walleye pollock is one of the type five fish species consumed in the United States. If you have ever eaten frozen fish sticks or had a fish sandwich at fast food restaurant then you have probably eaten pollock.

Personal Log

Good morning! It is currently 4:30am on Saturday, July 20th and I have just woken up for my first shift on the boat. So far, I have met scientists Abigail McCarthy and Troy Buckley, who will be working the day shift with me. I also met Ruth, an intern from the University of Washington and my bunkmate. It will be nice to have someone else on board who is also new to the experience!

Before talking about work, I’d like to share what we got up to in Kodiak before departing on the cruise. One thing to note – Chief Scientist Darin Jones explained that because this is the 3rd leg of the survey and the scientists are taking over from the previous group, we do not have any set up or calibration of equipment to do. If this had been leg 1 of the survey, the free days in port would have been spent doing those jobs. Lucky us!

After unpacking everything in our state rooms (bunks), we quickly set out to explore Kodiak. In two and a half days, were able to see a lot! Wednesday night, some friends of mine in town took us for a stroll on Near Island, followed by a yummy dinner at Noodle Bar.

Thursday morning, team building began with a run to Safeway and Walmart for all last minute necessities. The teacher in me couldn’t resist a fresh pack of sharpie markers and colored pencils. 🙂 In the afternoon, we walked along Spruce Cape where we picked a TON of blueberries and found the largest barnacle I have ever seen. 

Check out this Giant Acorn Barnacle!

After a short recoup back on the boat, Darin and Abigail were ready for an evening surf session at Fossil Beach. This beach is the farthest south you can access by road in Kodiak and the drive was BEAUTIFUL. Prior to the trip, I hadn’t looked up any pictures of Kodiak and so the treeless green mountains, cliffy coastlines and herds of cows were exciting to see. Once at the beach, we jumped in the ocean, watched a successful surf session and finished our team building with a fire and dinner on the beach.

Science and Technology Log

In just a few days of being here, I have already learned a lot about the workings of the ship and what we will be busy doing for the next three weeks. Here is a preview.

To begin, science shifts run from 4am – 4pm and 4pm – 4am. Throughout this entire time, acoustic data is being collected and read. Acoustic data is gathered by sending out sound waves from a transducer box attached to the bottom of a centerboard underneath the boat. The sound waves reverberate out and bounce off of anything with a different density than water. In the picture below, you can see a bold line on the screen with smaller dots above. Take a look and see if you can identify what the line and dots might represent.

Darin looks over morning acoustic data

If you thought the big bold lines on each screen were the seafloor, you were correct! Most of the little dots that appear above the sea floor are fish. Fish are identified from the sound waves bouncing off of their swim bladders. Swim bladders are the “bags” of air inside fish that inflate and deflate to allow the fish to raise and lower itself in the water column. Air has a different density compared to water and therefore shows up in the acoustics data.

acoustic data screen
Close up view of the acoustic data screen.

What is this acoustic data used for? There are 2 primary parts. The first is to identify where schools of fish are located and therefore areas well suited for collecting fish samples. The second is to calculate the total biomass of pollock in the water column by combining acoustics data with the actual measurements of fish caught in that same area. More specifics to come as I take part in the process throughout the survey. 

Did You Know?

On this survey, scientists do not catch/survey fish at night (when it is dark). The reason? At night, bottom dwelling species come up off the seafloor at night to feed. During the day they settle back down on the seafloor. The scientists are primarily interested in catching pollock, a mid water species, so they fish during daylight hours.

Updates to come later in the week. It is time for me to join the scientists and get ready process our first catch!

Science and Technology Log

For my second time out on a launch, I was assigned to a shoreline survey at Narrow Cape and around Ugak Island (see chart here).  Survey Tech Audrey Jerauld explained the logistics of the shoreline survey.  First, they try to confirm the presence of charted features (rocks) along the shore. (As you may remember from my last post, a rock is symbolized by an asterisk on the charts.) Then, they use the small boat’s lidar (LIght Detection And Ranging) to find the height of the rocks. Instead of using sound pulses, as with sonar, lidar uses pulses of laser light.  

Point Cloud
Point Cloud: Each dot represents a lidar “ping”, indicating the presence of features above the waterline

Once a rock was identified, Audrey photographed it and used the laser to find the height of the rock to add to the digital chart.  The launch we used for the shoreline survey was RA-2, a jet boat with a shallow draft that allows better access to the shoreline. We still had to be careful not to get too close to the rocks (or to the breakers crashing into the rocks) at certain points around Ugak Island.  The line parallel to the shore beyond which it is considered unsafe to survey is called the NALL (Navigable Area Limit Line). The NALL is determined by the crew, with many factors taken into account, such as shoreline features, marine organisms, and weather conditions.  An area with many rocks or a dangerously rocky ledge might be designated as “foul” on the charts.

Amanda and Audrey

I must pause here to emphasize how seriously everyone’s safety is taken, both on the small boats and the ship itself.  In addition to strict adherence to rules about the use of hard hats and Personal Flotation Devices in and around the launches, I have participated in several drills during my stay on the ship (Man Overboard, Fire and Emergency, and Abandon Ship), during which I was given specific roles and locations.  At the bottom of each printed Plan of the Day there is always a line that states, “NEVER shall the safety of life or property be compromised for data acquisition.” Once more, I appreciate how NOAA prioritizes the wellbeing of the people working here. It reminds me of my school district’s position about ensuring the safety of our students.  No institution can function properly where safety is not a fundamental concern.


Career Focus – Marine Engineer

Johnny Brewer joined the Navy in 1997.  A native of Houston, Texas, many of his family members had served in the military, so it seemed natural for him to choose a similar path after high school.  The Navy trained him as a marine engineer for a boiler ship. Nearly 15 years later he went into the Navy Reserve and transitioned to working for NOAA.

Working as an engineer requires mental and physical strength.  The Engineering Department is responsible for maintaining and updating all of the many working parts of the ship–not just the engine, as you might think! The engineers are in charge of the complex electrical systems, plumbing, heating and cooling, potable water, sewage, and the launches used for daily survey operations.  They fix everything that needs to be fixed, no matter how large or small the problem may be.

Johnny emphasized how important math is in his job.  Engineers must have a deep understanding of geometry (calculating area, volume, density, etc.) and be able to convert measurements between the metric and American systems, since the ship’s elements are from different parts of the world.  He also described how his job has given him opportunities to visit and even live in new places, such as Hawaii and Japan. Johnny said that when you stay in one place for too long you can become “stuck in a box,” unaware of the world of options waiting for you outside of the box.  As a teacher, I hope that my students take this message to heart.


Personal Log

In my last post I introduced Kimrie Zentmeyer, our Acting Chief Steward. In our conversation, she compared the ship to a house, the walls of which you cannot leave or communicate beyond, except by the ship’s restricted wi-fi, while you are underway.  I would like for my readers (especially my students) to imagine living like this, confined day in and day out to a single space, together with your work colleagues, without family or friends from home.  How would you adjust to this lifestyle? Do you have what it takes to live and work on a ship? Before you answer, consider the views from your back porch!

Q & A

Are there other NOAA ships working in Alaska?

Yes!  NOAA Ship Fairweather is Rainier’s sister-ship and is homeported in Ketchikan, Alaska.  Also, the fisheries survey vessel, NOAA Ship Oscar Dyson is homeported in Kodiak, not far from where we are currently located.

What did you eat for dinner?

This evening I had sauteed scallops, steamed broccoli, and vegetable beef stew. And lemon meringue pie. And a cherry turnover. And ice cream.

Let’s talk charts.  A chart is a map that shows specific details of the shoreline and the seafloor, including depth (usually in fathoms) and notable features.  Click here to view the chart of the area, “Chiniak Bay to Dangerous Cape.”  Can you find Saltery Cove, where we are currently anchored? How about Cape Greville and Sequel Point?  The latter are located at the northern and southern ends of the area that we surveyed with the launch last Wednesday afternoon.

If you look carefully, you will see many symbols along the shoreline.  An asterisk represents a rock awash that may only be visible when the water recedes at low tide.  A series of dots represents sandy shore, while small scallop shapes and circles denote breakers and stones, respectively.  The small, filled in triangles on land show where there are cliffs or steep slopes. The symbol that looks like a stick with small branches represents kelp.  Kelp is considered a possible hazard, since it can get wrapped around the propeller of a boat.

Now move your gaze to the ocean.  The numbers that you see are depth soundings, measured in fathoms.  Recall that one fathom equals 6 feet. This means that where you see a sounding of 9 fathoms, the water is actually 54 feet deep (relative to the mean lower low water datum).  If you are looking at the area near Cape Greville, all of the soundings that you see on the chart were taken between 1900 and 1939, before the invention of multibeam sonar. There was a magnitude 9.2 earthquake on March 27, 1964 that changed the depths and shapes of the landforms.  Finally, you should not discount the effects of weathering and erosion by wave action on this area.  The dynamic nature of it all makes the work that NOAA is doing all the more important for the safety of anyone at sea.

Career Focus – Steward

With so many people and so much work being done every day, how do you ensure good morale among the crew? You make sure that they are well fed!  That’s where the Stewards Department comes in to play. I met with Kimrie Zentmeyer, Acting Chief Steward, to learn how she and her staff take care of all of the people on the ship.  

Kimrie Zentmeyer, Acting Chief Steward

The Stewards Department is like a sweet grandmother, spoiling her grandbabies by providing good food and other comforts to the entire Rainier family.  Stewards plan and prepare the meals, supply appropriate linens and bedding, and maintain a positive, upbeat attitude in the face of a potentially stressful work environment. Stewards work long hours in close quarters and, as Kimrie says, provide the “customer service” of the ship. Kimrie herself has worked on ships for many years.  She started out as a mess person for Chevron Shipping when her daughter left home for college. As part of the NOAA Relief Pool, Kimrie has worked on ten of NOAA’s ships, filling positions on a temporary basis until permanent employees can be found. It is clear that she has a deep understanding of the emotional needs of a ship’s crew, and she enjoys the camaraderie and cooperation that develop in this unique work environment.

Personal Log

I would like to take some time to write about the ship. Rainier is a hydrographic survey vessel. (For more information about what that means, see my last post!)  Constructed in Jacksonville Florida, and then later commissioned in 1968, Rainier is one of the longest-serving ships in NOAA’s fleet.  It is named after Mount Rainier, a volcanic mountain in western Washington state.  Students might remember that this mountain is located near a continent-ocean convergent plate boundary between the North American and Juan de Fuca plates, where subduction has lead to the formation of the Cascade Volcanic Arc. Our ship’s home port is located in Newport, Oregon. Originally, however, the home port was in Seattle, Washington, and so it was christened after the iconic Mount Rainier.

NOAA Ship Rainier is 231 feet long from bow to stern.  There are six different levels, or decks, identified by the letters A-F moving upwards from the bottom of the ship.  Each deck is broken into numbered sections, or rooms.

To communicate a particular location, you might refer to the deck letter and section number.  You might also use the following vocabulary:

Port – the left side of the ship

Starboard – the right side of the ship

Fore – forward of the beam

Aft – behind the beam

Stern – the back end of the ship

Bow – the front end of the ship

D-Deck
Overhead diagram of the “D” Deck

My room is located on the E deck, one level below the bridge.  On the D deck we enjoy delicious, cafeteria-style meals in the mess, and we can work, read, relax, or watch movies in the lounge.  The steering takes place on the Bridge, the command center of the ship. I will highlight the bridge in a future post. Other common areas include the Plotting Room, the Holodeck, the Boat Deck, Flying Deck, and Fantail.  There is also a laundry room and even a gym! Although it can be a bit confusing at first, the ship’s layout makes sense and allows for efficiency without sacrificing the crew’s comfort.

Lona on launch RA-5
Yours truly, happy on RA-5

Today I went out on a launch for the first time.  The plan was to survey an area offshore and then move nearshore at low tide, with the water at its lowest level on the beach of Kodiak Island.  Survey Techs, Carl Stedman and Christina Brooks, showed me the software applications used to communicate with the coxswain and collect data. To choose the best frequency for our multibeam pulse, we needed to know the approximate depth of the area being surveyed.  If the water is deeper, you must use lower frequency sound waves, since higher frequency waves tend to attenuate, or weaken, as they travel. We chose a frequency of 300 kilohertz for a 60 meter depth. Periodically, the survey techs must cast a probe into the water.  The Sea-bird SeaCAT CTD (Conductivity, Temperature, Depth) measures the characteristics of the water, creating a sound velocity profile. This profile can tell us how quickly we should expect sound waves to travel through the water based upon the water’s temperature, salinity, and pressure.

Using the sound velocity profile allows the computer’s Seafloor Information System (SIS) to correct for changes in water density as data is being collected.  Once the profile was transmitted to SIS, we were ready to begin logging data.

Imagine that you are mowing your lawn.  To maximize efficiency you most likely will choose to mow back and forth in relatively straight paths, overlapping each new row with the previous row.  This is similar to how the offshore survey is carried out. As the boat travels at a speed of about 7 knots, the Kongsberg EM2040 multibeam sonar transducer sends out and receives pulses, which together create a swath.  The more shallow the water, the wider the base of the swath.

After lunch we changed to a nearshore area closer to Kodiak Island between Sequel Point and Cape Greville. It was important to wait for low tide before approaching the shore to avoid being stuck inshore as the tide is going out.  Even so, our coxswain was very careful to follow the edges of the last swaths logged. Since the swath area extends beyond the port and starboard sides of the boat, we could collect data from previously uncharted areas without driving directly above them.  In this way we found many rocks, invisible to the naked eye, that could have seriously damaged an unlucky fisherman!


Career Focus – Able Seaman

Our coxswain driving the boat today was Allan Quintana.

As an Able Seaman, Allan is part of the Deck Department, which functions primarily to keep track of the ship, manage the lines and anchoring, and deploy and drive the launches.  Allan started out working for the Navy and later transitioned to NOAA. A Miami native, he told me how he loves working at sea, in spite of the long stretches of time away from his friends and family back home.


Personal Log

If you have never been on a boat before, it is a unique experience. Attempts have been made by poets, explorers, scientists, naturalists, and others throughout history to capture the feeling of being at sea.  Although I’ve read many of their descriptions and tried to imagine myself in their shoes, nothing compares to experiencing it first-hand.

Standing on the bow of the anchored ship, looking out at the water, my body leaning to and fro, rising and falling, I am a sentient fishing bobber, continuously rocking but not really going anywhere.  My head feels somehow both heavy and light, and if I stand there long enough, I just might fall asleep under the spell of kinetic hypnosis. The motion of the launch is different. A smaller boat with far less mass is bullied by the swells. For a new crew member like me, it’s easy to be caught off guard and knocked over, unless you have a good grip. I stand alert, feet apart, one hand clasping a rail, as the more experienced crew move about, casually completing various tasks. I wonder how long it would take to become accustomed to the boat’s rising and falling.  Would my body gradually learn to anticipate the back and forth rocking? Would I eventually not feel any movement at all?

Personal Introduction

Finishing off the school year has never been so exciting as it is now, with an Alaskan adventure awaiting me!  My students are nearly as giddy as I am, and it is a pleasure to be able to share the experience with them through this blog.

In two weeks, I will leave my home in the Appalachian foothills of Georgia and fly to Anchorage, Alaska.  From there I will take a train to the port city of Seward, where I will board NOAA Ship Rainier.  For 11 days we will travel around Kodiak Island conducting a hydrographic survey, mapping the shape of the seafloor and coastline. The Alaska Hydrographic Survey Project is critical to those who live and work there, since it greatly improves the accuracy of maritime navigational charts, ensuring safer travel by sea.

Currently I teach Earth Science at East Hall Middle School in Gainesville, Georgia.  For the last five years, I have chosen to work in the wonderfully wacky world of sixth graders.  Our school boasts a diverse population of students, many of whom have little to no experience beyond their hometown.  It is my hope that the Teacher at Sea program will enrich my instruction, giving students a glimpse of what it is like to live and work on a ship dedicated to scientific research.  I am also looking forward to getting to know the people behind that research, learning what motivates them in the work that they do and what aspects of their jobs they find the most challenging.

Science and Technology Log

The ocean supports many ecosystems which contain a diversity of living things ranging in size from tiny microbes to whales as long as 95 feet.  Despite the fact that I am working on a hydrographic ship, when out on a skiff or while in port, I have had the opportunity to view some of these ecosystems and a number of the species found in them.

While the Rainier was in port in Homer, I spent some time at the Kachemak Bay National Estuarine Research Reserve which, like other estuaries, is among the most productive ecosystems in the world.  An estuary, with accompanying wetlands, is where the freshwater from a river meets and mixes with the salt water of the sea.  However, there are some estuaries that are made entirely from freshwater.  These estuaries are special places along the Great Lakes where freshwater from a river, with very different chemical and physical characteristics compared to the water from the lake, mixes with the lake water.

Because estuaries, like the Kachemak Bay Estuary, are extremely fragile ecosystems with so many plants and animals that rely on them, in 1972 Congress created the National Estuarine Research Reserve System which protects more than one million estuarine acres.

ESTRE

All estuaries, including the freshwater estuaries found on the Great Lakes, are affected by the changing tides.  Tides play an important part in the health of an estuary because they mix the water and are therefore are one of several factors that influence the properties (temperature, salinity, turbidity) of the water

Prior to my experience in Alaska, I had never realized what a vital role tides play in the life of living things, in a oceanic region.  Just as tides play an important role in the health and function of estuaries, they play a major role in the plants and animals I have seen and the hydrographic work being completed by the Rainier.  For example, the tides determine when and where the skiffs and multi beam launch boats will be deployed.  Between mean low tide and high tide the water depth can vary by as much as 12 feet and therefore low tide is the perfect time to send the skiffs out in to document the features (rocks, reefs, foul areas) of a specific area.

In addition to being the perfect time to take note of near shore features, low tide also provides the perfect opportunity to see some amazing sea life!  I have seen a variety of species while working aboard the Rainier, including eagles, deer, starfish, dolphins, whales, seals, cormorants, sea gulls, sea otters and puffins.  Unfortunately, it has been difficult to capture quality photos of many of these species, but I have included some of my better photos of marine life in the area and information that the scientists aboard the Rainier have shared with me:

Tufted Puffins:  Tufted Puffins are some of the most common sea birds in Alaska.  They have wings that propel them under water and a large bill which sheds its outer layer in late summer.

puff2

Double Crested Cormorants:  Dark colored birds that dive for and eat fish, crabs, shrimp, aquatic plants, and other marine life.  The birds nest in colonies and can be found in many inland areas in the United States.  The cormorants range extends throughout the Great Lakes and they are frequently considered to be a nuisance because they gorge themselves on fish, possibly decimating local fish populations.

Pisaster Starfish:  The tidal areas are some of the favorite areas starfish like to inhabit because they have an abundance of clams, which the starfish love to feed on.  To do so, the starfish uses powerful little suction cups to pull open the clam’s shell.

Glaucous-winged Gull:  The gulls are found along the coasts of Alaska and Washington State.  The average lifespan of Glaucous-winged Gull is approximately 15 years.

The hydrographic work in Uganik Bay continues even though there are moments to view the wildlife in the area.  I was part of the crew on board a boat equipped with multi beam sonar which returned to scan the “foot feature” meticulously mapped by the skiff.  During this process, the multi beam sonar is driven back and forth around the feature as close as the boat can safely get.  The multi beam does extend out to the sides of the boat which enables the sonar to produce an image to the left and right of the boat.  The sonar beam can reach out four times the depth of the water that the boat is working in.  For example, if we are working in six feet of water the multi beam will reach out a total of 24 feet across. Think of the sonar as if it was a beam coming from a flashlight, if you shine the light on the floor and hold the flashlight close to the floor, the beam will be small and intense.  On the other hand, if you hold the flashlight further from the floor the beam of light will cover a wider area but will not be as intense. The sonar’s coverage is similar, part of why working close to the shore is long and tedious work: in shallow water the multi beam does not cover a very wide area.

All Aboard!

I met Angelica on one of the first days aboard the Rainier and later spent some time with her, asking questions as she worked .  Angelica is very friendly, cheerful and a pleasure to talk with!  She graciously sat down with me for an interview when we were off shore of Kodiak, AK before returning to Uganik Bay.

IMG_1835
Assistant Survey Technician Angelica Patyten works on processing data from the multi beam sonar

Tell us a little about yourself:

I’m Angelica Patyten originally from Sacramento, CA and happy to be a part of NOAA’s scientific mission!  I have always been very interested in marine science, especially marine biology, oceanography and somewhat interested in fisheries.  Ever since I was a little kid I’ve always been interested in whales and dolphins.  My cousin said that when I was really young I was always drawing whales on paper and I’d always be going to the library to check out books on marine life.  I remember one of the defining moments was when I was in grade school, we took a trip to see the dolphins and orca whales and I thought they were amazing creatures.

As far as hobbies, I love anything that has to do with water sports, like diving and kayaking.  I also want to learn how to surf or try paddle boarding as well.

How did you discover NOAA?:

I just kind of “stumbled upon” NOAA right after I had graduated from college and knew that I wanted to work in marine science.  I was googling different agencies and saw that NOAA allows you to volunteer on some of their vessels.  So, I ended up volunteering for two weeks aboard the NOAA ship Rueben Lasker and absolutely loved it.  When I returned home, I applied online for employment with NOAA and it was about six months before I heard from back from them.  It was at that point that they asked me if I wanted to work for them on one of their research vessels.  It really was all good timing!

What are your primary responsibilities when working on the ship? 

My responsibilities right now include the processing of the data that comes in from the multi beam sonar.  I basically take the data and use a computer program to apply different settings to produce the best image that I can with the sonar data that I’m given.

What do you love about your work with NOAA?

I love the scenery here in Alaska and the people I work with are awesome!  We become like a family because we spend a lot of time together.  Honestly, working aboard the Rainier is a perfect fit for me because I love to travel, the scenery is amazing and the people I work with are great!


Personal Log:

Geoffrey Chaucer wrote, “time and tide wait for no man.”  Chaucer’s words are so fitting for my time aboard the Rainier which is going so quickly and continues to revolve around the tides.

Science and Technology Log

I’m continually searching for ways to connect what I am learning to what is relevant to my students back home in the Midwest.  So, as we left Homer, AK for our survey mission in Kodiak Island’s Uganik Bay, I was already thinking of how I could relate our upcoming survey work to my students’ academic needs and personal interests.  As soon as the Rainier moved away from Homer and more of the ocean came into view, I stood in awe of how much of our planet is covered with water.  It’s fascinating to think of our world as having one big ocean with many basins, such as the North Pacific, South Pacific, North Atlantic, South Atlantic, Indian, Southern and Arctic.  The study of ocean and its basins is one of the most relevant topics that I can teach when considering the following:

  • the ocean covers approximately 70% of our planet’s surface
  • the ocean is connected to all of our major watersheds
  • the ocean plays a significant part in our planet’s water cycle
  • the ocean has a large impact on our weather and climate
  • the majority of my students have not had any firsthand experience with the ocean

 

IMG_1675
Earth’s One Big Ocean as seen from outside of Homer, AK

 

Each of the ocean basins is composed of the sea floor and all of its geological features which vary in size and shape.  The Rainier will be mapping the features of the sea floor of the Uganik Bay in order to produce detailed charts for use by mariners.  The last survey of Uganik Bay was completed in 1908 when surveyors simply deployed a lead weight on a string over the edge of a boat in order to measure the depth of the water.  However, one of the problems with the charts made using the lead line method, is that the lead line was only deployed approximately every 100 meters or more which left large gaps in the data.  Although not in the Uganik Bay, in the 1930s NOAA began using single beam sonar to measure the distance from a ship’s hull to the sea floor which made surveying faster but still left large gaps in the data. Fast forward from approximately 100 years ago when lead lines were being used for surveying to today and you will find the scientists on the Rainier using something called a multibeam sonar system.  A multibeam sonar system sends out sound waves in a fan shape from the bottom of the ship’s hull.  The amount of time it takes for the sound waves to bounce off the seabed and return to a receiver is used to determine water depth.  The multibeam sonar will allow our team on the Rainier to map 100% of the ocean’s floor in the survey area that we have been assigned.

NOAA Corps Junior Officer Shelley Devereaux

The folks I am working with are some of the most knowledgeable and fascinating people that I have met so far on this voyage and Shelley Devereaux from Virginia is one of those people.  Shelley serves as a junior officer in the NOAA  (National Oceanic and Atmospheric Administration) Corps and has been working aboard the Rainier for the past year.  The NOAA Commissioned Officer Corps is one of the seven uniformed services of the United States and trains officers to operate ships, fly aircraft, help with research, conduct dive operations, and serve in other staff positions throughout NOAA.

Here is what Shelley shared with me when I interviewed her one afternoon.

Tell us a little about yourself:  I’m originally from the rural mountains of Appalachia and moved to Washington DC after college.  I lived in DC for about seven years before I joined the NOAA Corps and while in DC I really enjoyed cycling, hiking, cooking, baking and beer brewing.

How did you discover NOAA Corps and what do you love most about your job in the NOAA Corps?

I went to Washington DC after I received my undergraduate degree in math and worked a lot of different jobs in a lot of different fields.  In time, I decided to change careers and went to graduate school for GIS (Geographic Information Systems) because I like the data management side of the degree and the versatility that the degree could offer me.  I was working as a GIS analyst when my Uncle met an officer in the NOAA Corps who talked with my Uncle about the NOAA Corps.  After that, my Uncle told me about NOAA Corps and the more I found out about NOAA Corps the more I liked it.  Especially the hydro side!  In the NOAA Corps each of your assignments really develops on your skill base and you get to be involved in a very hands on way.  Just this morning I was out on a skiff literally looking to determine what level a rock was in the water.  And, later in my career I can serve an operations officer.  So I loved the fact that I could join the NOAA Corps, be out on ship collecting data while getting my hands dirty (or at least wet!), and then progress on to other interesting things.  I love getting to be part of all the aspects of ship life and being a surveyor.   It’s a wonderful feeling knowing that what we do here has a tangible effect on the community and the public because we are making the water safer for the people who use it.

DSCN0011
NOAA Corps Junior Officer Shelley Devereaux manages her sheets during near shore work in Uganik Bay

What are your primary responsibilities when working on the ship?  

I am an ensign junior officer on a survey ship.  Survey ships operate differently than other ships in the NOAA fleet with half of my responsibilities falling on the junior officer side of ship operations which includes driving the ship when we are underway, working towards my officer of the deck certification, working as a medical officer, damage control officer and helping with emergency drills.  The other half of what I get to do is the survey side.  Right now I am in charge of a small section called a sheets and I am in charge of processing the data from the sheets in a descriptive report about the area surveyed.  So, about half science and half ship operations is what I do and that’s a really good mix for me.  As a junior officer we are very fortunate that we have the opportunity to and are expected to learn the entire science of hydrography.

IMG_1819
Junior Officer Shelley Devereaux checks the ship’s radar

What kind of education do you need to have this job and what advice do you have for young people interested in a career like yours?

You need a college degree with a lot of credits in science and/or math.  Knowing the science that is happening on the ship is important to help your understanding of the operations on the ship which helps you be a better ship operator. Realize that there are a lot of opportunities in the world that are not always obvious and you need to be aggressive in pursuing them.

Did You Know?

Glass floats or Japanese fishing floats are a popular collectors’ item.  The floats were used on Japanese fishing nets and have traveled hundreds and possibly thousands of miles via ocean currents to reach the Alaskan shoreline. The floats come in many colors and sizes and if you’re not lucky enough to find one while beach combing, authentic floats and/or reproductions can be found in gift shops along the Alaskan coast.

September 8 – 24 , 2015

Mission: Hydrographic Survey
Geographical area of Research: Kodiak Island, Alaska
Date: September 21, 2015

Current Location: Viecoda Bay, North Kodiak, Alaska

After learning how areas to be studied are decided, organized and surveyed, I wanted to see what happens after the data is collected.  I spent some time in the Plotting room with NOAA visiting physical scientist Adam Argento.  Adam instructed me on hydrographic research and what is involved with completing their work.  Needless to say, using the term “blowing my mind” is very appropriate here.

Sitting with Adam and discussing the work that is accomplished was great.  He even made me think of space – and you know how much I love a space tie-in!!  While we were talking about the data that would be collected we began speaking of how do researchers know where the ship is?  You might automatically think of GPS (Global Positioning Systems).  We have them on our phones, in our cars and other forms of technology to help us find our way home, but the GPS systems we use are not as accurate as NOAA needs.

On Rainier they need to know exactly where they are!!  Just like when we give you rules you need to follow in doing your work, the researchers here have very limited parameters for creating/updating their charts for safety.  While collecting data they want to make sure that the charts are as accurate as they can make them.  If the data collected is off just a bit, there could be a dangerous situation.  The people updating the charts work very hard to create high quality and safe charts.

Adam showed me some of the satellite receivers on the ship and launches.  We couldn’t reach the Rainier receivers, but see the picture of a receiver on a launch, they are much smaller than I imagined.  Each launch has two receivers at least six feet apart.  They are needed for the satellites to know which direction the launch is going in. The satellites use the smallest of time measurements sent down and received back between the two, but it works!

Adam asked me some questions – now it’s your turn to think about this…How would Rainier know exactly where it is?  You might say it uses a GPS because I just mentioned it and simply put, yes it does.  Except, one, two even three satellites will not give Rainier the accurate positioning they need.  Four satellites can give Rainier a specific point.  Just take a moment and think about this.  In short, four satellites will give you a good position, but Rainier uses up to seven to be much more accurate.  For more information on satellites check out this website: http://www.gma.org/surfing/sats.html#nav

Another question… how do the satellites know where they are?  We can’t use a marker on the Earth reliably, or to the level that NOAA needs, because our planet is constantly moving (think tectonic plates and earthquakes).   Are you ready?  Adam told me satellites use pulsing QUASARS that are far out in space to know exactly where they are!!! (In case you were wondering, this is the part where my mind was blown, I thought they used land based markers).

Like I mentioned earlier, the CARIS program takes all of the data, including changes in the Earth’s Ionosphere and differences in the ocean water due to CDT (conductivity, depth and temperature) and puts it together to create a working document or chart.  This is a lot of information that needs to be controlled.  Adam works for NOAA in Seattle so he will be part of the team taking the data and putting it into more accurate charts once he gets back on land.  A pretty cool job if you ask me!!

Path to Rainier

To continue sharing some of the fascinating people on Rainier, I sat down with Rainier General Vessel Assistant (GVA) Carl Stedman to learn how he came to work here.  Carl started his career in the Army and retired after 20 yrs.  Incredibly, after proudly serving our country for so long, he then went to college and earned a bachelor’s degree in finance from San Francisco State.

About half way through earning his MBA (Masters of Business Administration) he decided to take some time off.  He rode his motorcycle around the US for three months.  Realizing wearing a suit or working in a cubicle would not make him happy, he moved to Virginia and opened his own coffee shop for three years where he met his wife.  He then worked as a patient service manager in Norfolk hospital.  With more introspection he thought back to his time in the Army.  After having lived in Germany and serving in other areas of the world for a long time, he remembered his time on an Army ship for the last 7 years of  his Army career and how much he enjoyed it.  He then applied to work for NOAA and was put on Rainier.

On Rainier, Carl has some very interesting jobs!!  Along with the very busy job as a GVA, Carl is also an Advanced Firefighter and is on the first response team (he was also in his firefighter outfit when we had drills, but I did not get a picture of him).  He is an MPIC (Medical Person In Charge) which is like an EMT that we have on land.  Another job he has (and one that makes me nervous just thinking about it) is as a Confined Space Rescuer.  Yikes… he clearly does not have claustrophobia!!  Another exciting job he has is the driver for the fast rescue boat that is on Rainier.  Carl is another unique person on this incredible ship and I feel very safe knowing he is around.  Thank you, Carl, for taking the time to chat with me and show me so much!!!

This wonderful crew has been teaching me a great deal about this ship.  One day, acting Boatswain (pronounced Bo-son) Jason Kinyon took time to teach me how to work the two smaller cranes on the bow of the ship.  He had me move a filled bucket of water to different areas on the bow WITHOUT SPILLING ANY OF IT!!

I really liked it!!!  The most challenging part was when he sat down right next to where I had to place my bucket of water.  I did not want to get the deck boss wet and I didn’t!  I did spill a little bit on one of the hatches though.  Jason was very patient showing me all the tricks to moving the crane!  Bring on the big aft crane next!!!!

When we went to the fuel pier in Kodiak I was able to throw the “heave line” that goes up to the dock and is then knotted around the bigger mooring lines so they can be pulled up to the pier.

I feel the need to add that three big, strong deck crew who were back in the fantail of the ship with me missed where they had to throw their lines.  GVA Carl Stedman was very reassuring to me and I got the line where it had to go.  Everyone on the ship was talking about how I made it on the first try when the seasoned crew did not.  In case you are wondering, yes, that is a cruise ship in the distance at the Kodiak public dock.

To name just a few more things, I have been shown lots about navigation, I have also driven the launch, worked the davits that raise and lower the launches, learned about the anchor and basically anything else I can learn about and what people are able to teach me.  Thank you, again, to everyone for teaching the teacher so I can share this amazing experience with others!!

Rebecca Loy, Does Rainier Run on Diesel or STEAM?  September 14, 2015

Mission: Hydrographic Survey
Geographical area of Research: Kodiak Island, Alaska
Date: September 14, 2015

Current Location: South Arm of Uganik Bay, Kodiak Island, Alaska

To answer this question, Rainier runs on both diesel and STEAM.  The diesel keeps this ship running where it needs to go and the engineers are masterful at keeping this ship maintained.  The STEAM is everywhere, and I am not just talking about water steam in a pipe or in the galley.  This ship has serious Science, Technology, Engineering, Arts and Math!!

I met with acting (Executive Officer) XO LT Adam Pfundt and acting (Field Ops Officer) FOO LT Steve Loy (even though Loy is a unique name, we are not related – but it is pretty cool that another Loy is here).  They were discussing who was going to lead certain jobs.  I learned a great deal about the process needed.  During research, an area in review is called a “sheet”.  Why do you think they call the areas sheets and not something else?  Do you think there could be some historical mariner significance?

Map with NOAA sheet areas listed

Like most tasks on Rainier, research begins with a geographical area being assigned to a manager, assistant plus a mentor.  They will work together as a team on their sheet until the hydrographic branch of NOAA accepts the data.  Like I mentioned in my second blog entry, this could take weeks or months after the initial data collection to complete.

I have decided to use sheet number H12692, which was just assigned to the team of  ENS Matt Bissell, manager, ENS Shelley Deveraux as assistant, and LT Steve Loy as mentor this past week.  Can you find H12692 on the photo above?

All team members are responsible for maintaining work logs so they can report on them.  Even here writing & communication is very important – remember this when I help you with YOUR writing!  Here is a brief overview of the duties:

Sheet Manager – this is the biggest of the jobs given.  The sheet manager is responsible for organizing the team.  This person needs to prepare the area to be studied by separating it into more manageable areas called polygon plans.

Sheet H12962 in polygon planning.
Sheet H12962 in polygon planning.

They decide which area gets studied by the large Rainier or if a smaller launch is needed.  The smaller launches are good for areas closer to the shore or shallow areas.

The manager has to know if Rainier should use its multibeam echolocation sounder (MBES) in large runs or drag its Side Scan Sonar (SSS) behind it in the area to be studied.  Another option the manager has to decide is do they need to use the MBES or Side Scan Sonars that are mounted on the smaller launches and where should this be.

ENS Bissell has a many choices to make to get the best information possible.  Looking at the polygon grid ENS Bissell organized can you pick out which areas Rainier will cover?

Managers need to attend meetings and review data that was processed the night before.  They do this to see if any problems were encountered and if an area needs to be scanned again.  The manager uses the immense CARIS HIPS and SIPS marine data processing program, prepares dive teams if needed, does more reviewing of data and organizes the pilots that take the launches closer to shore.  This is truly just a brief overview.  Sheet Manager is a very important job.

Sheet Assistant – The assistant works very hard right alongside the Sheet Manager.  This person is in training as well and will someday be a Sheet Manager.  It is important for the Sheet Manager to give the assistant guidance to learn.   The assistant needs to ask questions so they can be an effective manager in the future.  They need to set up the launches, help with polygon plans, maintain the bottom sample notebook, load charts, assist with data acquisition and follow what the manager needs them to do.

Sheet Mentor – The mentor’s role is an advisor to the manager, especially if this is the first time someone is managing.  They also train the sheet assistant and work between the FOO and the management team (in this case the FOO is also the mentor).  The more the mentor can teach the assistant the easier their transition will be from assistant to manager in the future.

Once all of the extensive planning is taken care of, this team begins to collect data.  This is the actual field work that Rainier does!  I know all of you at school were most excited to hear about this!

To begin, we went ashore in the South Arm of Uganik Bay, northern Kodiak Island and had to place a tide gauge station.  To begin the scuba divers had to place part of the equipment called the orifice under water.  This orifice holds air bubbles.  When the tide is higher and the water level is high, more bubbles will be pushed out of the orifice letting the system know that the water level is up.  The more water pressure on the orifice, the higher the tide level and the opposite is also true.  This information is sent to the satellite links where solar panels and batteries keep everything powered so people on the ship can read the data.  We also had to place tide benchmarks in five different areas near the tide station.  I helped with tide benchmark 7588 E or “Echo” which was the fifth benchmark to go in.  Due to movement in the Earth, we need to have tide benchmarks throughout the areas we are studying so when the ship returns in 30 days they will have accurate information.

I worked very hard drilling into just the right rock to cement it down (I actually drilled in 4 areas before this one, but the shale kept breaking apart, LT Pfundt found this great spot with a more stable rock).  Hydrographic Assistant Survey Tech (HAST) Michael Bloom and I made a great team working together.  It took 1 1/2 days to place everything, survey and link the systems plus take 3 hours of observations for the tides.  During this 3 hour period the observer checks the water level on the staff every 6 minutes.  This is a lot of close observation to make sure everything is running properly!

Surveying all the tide benchmarks!

Do you know why we would need to know when the sea rises and falls?  Sometimes it can change over 6 feet in depth – two times per day here in the Pacific!!  We need to know the levels for the charts that are being made.  The researchers are looking at updating water depths on a chart.  They will use the tide level that is lowest to be safest.  This will give boats traveling above the best depth for clearance below them.  The opposite is true if there is bridge on a chart.  The researchers will use the highest tide depth so ships can know if they can make it under a bridge.  Knowing tides is very important to chart development!  Here is some more information on Vertical Control-Tides.

Another fascinating person on board is Hydrographic Survey Technician Eli Smith.  Eli has been on Rainier for 1 1/2 years now.  He started as a Hydrographic Assistant Survey Tech  in May of 2014.  Originally, he graduated from Western Washington University with a BA in Geology.  I was curious how he went from being a geologist in the oil fields of Denver to working on the ocean.  While he was in Denver, Eli would take soil samples.  So many samples that he was called a “Mud Logger” which is a pretty interesting term even though Eli didn’t enjoy it very much.  He did a lot of “soul searching” and realized he needed to do something else.  Between remembering an ocean based field experience in college off the coast of Hawaii and contacting a career counselor, Eli was led to NOAA.  He was pleased when he was placed on Rainier.

On Rainier, Eli works a great deal up in the Plotting room or in another room called the “Hologram Room” where survey techs also work.  Currently, he is a sheet manager for sheet H12691.  This sheet includes Viekoda Bay and Terror Bay.  You can see his area in the photo above.  Eli has been  hard at work doing his own polygon plot and preparing plans for his sheet.  He is also part of the Tides Team placing tidal gauges in areas that are being studied.

When Eli is not working, he has his bike on board and likes to ride that when he can.  He is also a hiker and snowboarder.  I appreciate Eli spending some time with me telling me about himself and all your help on shore.  Thank you!

I found out the room they gave me is called the “Princess Suite.”  I  learned this name comes from using the initials PS for the visiting Physical Scientists who often come aboard.  I extend an apology to visiting NOAA physical scientist Adam Argento.  You will learn about Adam in a future blog.  He did not get to sleep in the wonderful “Princess Suite” on this trip.

Current Location: transitioning between Shelikoff Strait and Uganik Bay, North Kodiak Island, Alaska

As I mentioned earlier, safety is top priority here on Rainier.  The crew is required to have safety drills within 24 hours of leaving port.  This includes drills such as Fire and Emergency drills, Man Over Board (MOB) drills and Abandon Ship drills.

When I arrived I was quickly told how to find 2 ways out of my cabin.  My cabin also has a device called an EEBD – Emergency Escape Breathing Device that will allow me to breathe for 10 minutes in a smoky corridor if needed.  Each and every cabin has these and they are also in various places around the ship.

All new crew and visitors are given a thorough safety briefing before we leave port.  We started by doing some paperwork and discussing what everything means.  Then, ENS Danial Palance took us around the ship and showed us the important areas.  He made sure I could find my safe places to report to since I am so new to the ship.

My Rainier safety card
My Rainier safety card

Every person, including me, has a job during an emergency.  Each person is given a “bunk card” that is held near your sleeping bunk.  It lists the three main emergencies we practice and where each person reports to.

Fire and Emergency Drills – the ship’s whistle will blow for a long 10 second blast when there is a fire or other emergency.  Go ahead and slowly count to 10 to see how long it is – 1 Mississippi, 2 Mississippi, 3…

This will definitely get your attention!   If it is a drill it will be announced.  If not, it will say this is an emergency.  My job is to get to the “BRAVO station” which is on the Fantail or back of the ship near the boat shop.  My primary duty is to “assist as directed” if help is needed.   All over the ship are stations for the firefighters. What I find most interesting is these are not people they bring on board specifically… it is the crew you see around you who have also trained to be Firefighters and Advanced Firefighters!  ENS Palance is one of them!

The fire station in the mess hall.
The fire station in the mess hall.

Also throughout the ship you can see Fire Stations and fire extinguishers, fire alarm boxes, radios for communication.  Some of the areas with more dangerous items (like paint or the machine shop) are labeled “CO2 PROTECTED SPACE”.  I was most curious about this.  What do you think CO2 and fires have in common?  If you answered that fires need oxygen to burn and CO2 will put a fire out then you are correct.  In one area of the ship there are many large canisters with CO2 in them.  If there is a bad fire in one of the CO2 protected spaces, someone can send the CO2 to that area and put the fire out.  It will remove all the oxygen from the space.

Man Over Board drills – On a ship if someone falls into the water you will hear the whistle blow for 3 long blasts.

Along with many other orange safety rings, this one has smoke attached to it.
Along with many other orange safety rings, this one has smoke attached to it.

If you are the person who saw this, you will need to keep your eye on the person and let others know.  Everyone has a station for this as well.  My job is to report to the “Flying bridge” on top of the ship and be a lookout and help as needed.  The ship has many orange safety rings that can be throw overboard to someone.  There are also two rings with smoke signals attached that can be released from both port (left side) and starboard (right side) of the ship.  We learned how to release those as well.  Rainier has to do monthly drills for MOB.  They don’t actually put someone in the water for this, it is usually a buoy or it could be “Oscar” the medical mannequin (He must be Rainier’s version of “Buster” from the show Mythbusters).

In my survival suit!
In my survival suit!

Abandon Ship drills – Being out on the cold waters of Alaska and leaving this ship is a scary thought, but it needs to be practiced.  Everyone has their own Survival Suits to wear for these drills.  Check me out with mine!!  We also need to bring long sleeved shirts, warm hats and flotation devices with us.  I will be reporting to Liferaft #4 on the port side of the ship with Liferaft #3 on the starboard side as back up.  My indoor meeting place is in the Wardroom and, again, I assist as directed.  If we have to leave the ship, people have jobs to go get the EPIRB which is an Emergency Position Indicating Radio Beacon, the SART is a Search and Rescue Transponder and the GMDSS which are Global Maritime Distress Safety Signal.  All of these will help the Coast Guard rescue us!!

I have had my training, and you know what needs to be done.  Now, time for the real drills at sea!!!

Suddenly, we hear a long 10 second whistle… it was the drill for fire and emergency.  Everyone quickly went to their assigned areas.  There was a fire near the mess hall and the fire team was on the job!!  ENS McKay and AB Wright worked on putting the fire out.  Below are some pictures of them in their fire gear!

The fire drill turned into an Abandoned Ship drill.  Calmly and quickly, everyone gathered their survival suits, a warm hat, long sleeved shirt and their PFD (personal floatation device) and went to their station.  Everyone had to put their survival suits on.  ENS McKay was my group leader and he had to help me with mine.  He was incredibly fast putting his on and gave me some great pointers on being quicker in a real emergency.

Path to Rainier

This crew is truly an incredible bunch.  I thought it would be interesting for others to see how people ended up working here.   While I would like to highlight everyone, I could only pick a few.

The first person I want everyone to meet is Able Seaman (AB) Lindsey Houska.  Lindsey is one of the deck hands on Rainier.   I wanted to know what path led her to this unique work place.

Lindsey started with a degree in Economics from South Dakota State University and worked in Montana for the USDA (U.S Department of Agriculture) for 4 1/2 years.  She realized she wanted to get a bit more out of life than working at a desk.  She sold her house and car, stored her belongings with her parents and went to Indonesia to volunteer instructing farmers on better growing practices.  This was the beginning of her life adventures!  After 3 months living in Indonesia and 5 months traveling other areas of Southeast Asia, she headed out to Australia.  This incredibly hard working woman did a few jobs but ended up working on a commercial fishing vessel catching prawns on the West Coast of Australia.  Later, she got a job in Seattle and South East Alaska as a deck hand on a luxury yacht.  Realizing she had a love of positive environmental practices she wanted to do more for the world in general.  This is when Lindsey applied to work for NOAA.  NOAA are true stewards of the ocean!

On Rainier, Lindsey has been a very busy deck hand for nearly 2 years.  She loves working with all the other deck hands and they have an amazing camaraderie with each other.   I learned so much more about her job when we sat down together.  Lindsey is a trained fire fighter, has been to radar school and even has her captain’s license for smaller vessels.  She works hard with boat deployment, maintenance on the weather deck, inport bridge watch for security and anchor watch so the ship stays in place when it is at anchor.  She also works the cranes, does lookout on the flying bridge and can be a helmsman steering the ship.

In her free time, Lindsey can be found reading, working out in the gym on board, meditating for some quiet time and she also has a bicycle on board that she likes to ride when the ship is in port.  When I asked Lindsey what she did to reduce stress on the job, she said having a good sense of humor with colleagues goes a long way.  They also enjoy time in port together and having meals together.  This amazing woman has traveled all over the world including most of Southeast Asia, all over Australia and New Zealand.  She has been to Europe, Mexico, British Columbia and Manitoba, Canada.  Incredibly, but not surprising as I get to know her, many of the areas Lindsey backpacked to on her own!

I am truly impressed by this lady; how hard she works and how kind she has been to me.  Thank you, Lindsey, for letting me get to know you better!

TEAMWORK SAFETY FIRST   Three words that I have discovered run Rainier.  I am incredibly impressed by the teamwork, communication, hard work and commitment to our oceans that is evident here.  The umbrella over all of this is an even bigger obligation to safety.  Above I have highlighted just a bit of what makes this ship work in regard to safety.  In future blogs you will read more about this topic when you learn about the people here.   Needless to say, even though we will be out in very big, deep waters and in narrow bays with tall mountains, I feel incredibly safe in the hands of this reliable crew.

Even getting fuel, this team is safe. Here a fuel boom went around the ship.

Science and Technology Log

Much like the the lab reports we do in class, hydrographers have a tremendous amount of work to do prior to going into the field.  As we make the transit from Rainier’s home port of Newport to our charting location of Kodiak Island, hydrographers are working long hours in the plotting room planning their season’s work. Today’s log is about a software program called CARIS that hydrographers use to plan their project and guide data collection through the season.  This morning, Ensign Micki Ream planned her season’s work in the Plot Room on CARIS.  This afternoon, she walked out the plot room door and onto the bridge where she navigated Rainier through the narrow Blackney Passage of the Inside Passage.   Prior to taking over the bridge, I watched as Ensign Ream as she plotted her project area for the season.  She has been assigned Cape Uganik, an area of North Kodiak Island in the vicinity of Raspberry Island.  The area was chosen to survey due to boat traffic and because the last survey completed was in 1908 by lead line.  Here you can see the original survey report and an image of how data was collect at that time (1908 Survey of Ensign Ream’s Survey Area). Ensign Micki Ream explained that the charts were called “sheets,” because originally, they were sheets of paper, sent out with the surveyor into the field.  While we still call them sheets, they are now in electronic form, just like the sheet below representing one of two project areas ENS Ream will most likely work on this summer.

Ensign Ream's task is to break this large polygon into smaller manageable parts.
Ensign Ream’s task is to break this large polygon into smaller manageable parts. Challenge:  print a copy of this map and come up with 30 smaller polygons to assign to your team to survey before you scroll down to see Ensign Ream’s plan.

Why make polygons instead of sending several launches out to your work area and tell them to start on opposite ends and meet in the middle? The polygons are a way for hydrographers to break a large amount of work into manageable tasks. Commander Rick Brennan, the Commanding Officer, explains “polygons are designed based upon the depth of the water, the time it will take to complete, and the oceanographic condition, particularly speed of sound through water.  Areas that are suspected to have a higher variability in sound speed will get smaller polygons to manage errors from sound speed.”

Also, imagine sending several launch boats out into a large area to work without telling them where to go. Polygons provide a plan for several boats to work safely in an area without running into each other.  It allows areas to be assigned to people based upon their skills.  The coxswains, boat drivers, with a lot of experience and skill, will take the near shore polygons, and the newer coxswains will take less hazardous, deeper water.

Another reason to break your sheet into polygons is to maintain team moral.  By breaking a large task into small assignments people feel a sense of accomplishment. As she divided her large polygon into 30 smaller polygons, Ensign Micki Ream kept in mind many variables. First, she considers the depth of the water.  The sonar produces a swath of data as the survey vessel proceeds along its course.  As the water gets deeper, the swath gets wider, so you can make a bigger polygon in deeper water. As she drew her polygons, she followed contour lines as much as possible while keeping lines straight.  The more like a quadrilateral a polygon is, the easier it is for a boat to cover the area, just like mowing a rectangular lawn. In her polygons, she cut out areas that are blue (shallow), rocky areas and kelp beds, because those areas are hazardous to boats.  While the hydrographer in charge and coxswain (boat driver), should use best practices and not survey these areas by boat, sometimes they rely on the polygon assignment.

Here is Ensign Ream's Proposal for how to complete this summer's work. How does it compare to your proposal?
Here is Ensign Ream’s Proposal for how to complete this summer’s work. How does it compare to your proposal?

Once she has drawn up her plan, Ensign Micki Ream roughly measures the average length and width of her polygons and puts that data into a Polygon Time Log form that a co-worker created on Rainier last season.  The form also takes into account the depth and gives an estimate of time it will take to complete the polygon.  This Time Log is just one of the many pieces of technology or equipment that crew invents to make their lives and jobs easier.

Polygon Time Logs estimate how long it will take to complete a sheet.
Polygon Time Logs estimate how long it will take to complete a sheet.

The fun part of this process is naming your polygons so that hydrographers in the field can report back to you their progress.  Traditional alphabetical and numerical labels are often used, but Ensign Micki Ream is naming some of her polygons after ’90s rock bands this year. Once the polygon is named, the sheet manager, Ensign Ream, develops a boat sheet for a hydrographer in charge (HIC):  this is their assignment for the day. Typically, they send out three to four people on a launch, including the HIC, coxswain and an extra hand. There are always new people aboard Rainier, so there are often other people in the launch being trained.  There are enough immersion suits for 4 people but ideally there are three people to help with launching the boat and completing the day’s work.  Communication between the HIC and coxswain is essential to get data for ocean depths in all areas of their polygon as they determine the direction to collect data in their work area.  Now, at least, the hydrographer and coxswain know where to start and stop, and are confident that their sheet manager has done her best to send them into a safe area to collect the data needed to make new charts.

 

Since Ensign Ream’s polygon plan is an estimate, the time to complete each polygon may be longer or shorter than estimated.  Variables such as the constantly changing depth of the ocean, weather, experience and equipment of the crew collecting data, and a myriad of other variables, known and unknown, make scheduling and completing surveys a constantly moving target.  There are two guarantees however:  flexibility is required to work on the crew and ultimately winter will force a pause to Rainier’s work.

Spotlight on a Scientist

Although I have been on Rainier for only several days, I am blown away by the incredible skills crew members acquire in short amounts of time.  Ensign Micki Ream is the perfect example:   In January, 2013, she joined the NOAA Corps which provides operational support for NOAA’s scientific missions.  During a six month officer training, she was trained in the basics of navigation. On June 2, 2013, she joined Rainier crew. In February, 2014 NOAA sent her to a one month Basic Hydrography School where she learned hydrography principles and how to use various software programs. Throughout her short time at NOAA, she has had significant and varied on the job training with scientific, managerial and navigational work.The rest of her skills are on the job training with an end goal of Officer of the Deck (similar to a mate in commercial sailing) and Hydrographer in Charge.

Here, Ensign Ream is modifying polygon names from 90's rock bands to the 12 Days of Christmas.  There is plenty of room for creativity here!

Ensign Micki Ream does have a background in science which she is putting to use every day.  Originally from Seattle, she started her career with NOAA in June, 2009, after obtaining a Marine Biology degree at Stanford University.  Her first position was with the Office of National Marine Sanctuaries Program, which provided her with an internship and scholarship to acquire a Master’s Degree, also from Stanford, in Communicating Ocean Science. Just a little over one year after coming to NOAA Corps, she is a hydrographer in training and safely navigating a very impressive ship as part of a bridge team, including highly skilled navigational experts such as Ensign J.C. Clark and Commander Brennan.  Where else could you get training, experience and on the job support in so many diverse areas but with NOAA Hydro?

The food is absolutely amazing on board.  Tonight’s dinner options were roast prime beef, cut to order, au jus, creamy smoked salmon casserole, farro vegetable casserole, baked potatoes with fixings, asparagus and several different kinds of cake and fruit. In the evenings, snacks are also available.  My biggest challenge has been to pace myself with the the quantity of food I eat, particularly since taking long hikes after dinner is not an option. I feel very well cared for aboard Rainier. P1000587

As you can see from my weather data section, the wind speed this morning was up to 42.65 knots.  We had waves near 18 feet and thus the Oscar Dyson ran for cover and tucked itself in an inlet on the North side of Kodiak Island called Spiridon Bay.  The Oscar Dyson’s location can be viewed in near real-time using NOAA’s Shiptracker website.   The screenshot above was taken from the Shiptracker website when we were hiding from the weather. The weather forecast from NOAA’s Alaska Region Headquarters shows that the winds should diminish over the next few days.  I’m thankful to hear that!

Since the Dyson has been in safe harbor in Spiridon Bay for the last few hours, I have had some time to catch up on some blogging!  Let’s backtrack a few days to Wednesday, September 4th, when the Dyson left Kodiak to begin its journey in the Gulf of Alaska.  We headed out after 1PM to pick up where the last cruise left off in the research grid.  We reached our first station later in the afternoon and began work.  A station is a pre-determined location where we complete two of our surveys (see map below).  The circles on the map represent a station location in the survey grid.  The solid circles are from leg 1 of the cruise that took place in August and the hollow circles represent leg 2 of the cruise, which is the leg on which I am sailing.

The first step once we reach a station is to deploy a Bongo net to collect marine zooplankton and the second step is to begin trawling with an anchovy net to capture small, pelagic juvenile pollock and forage fishes that are part of the main study for this cruise. Pelagic fish live near the surface of the water or in the water column, but not near the bottom or close to the shore.  Zooplankton are “animal plankton”.  The generic definition of plankton is: small, floating or somewhat motile (able to move on their own) organisms that live in a body of water. Some zooplankton are the larval (beginning) stages of crabs, worms, or shellfish.  Other types of zooplankton stay in the planktonic stage for the entirety of their lives. In other words, they don’t “grow up” to become something like a shrimp or crab.

Station Map
Station map for leg 1 and leg 2 of the juvenile pollock survey. I am on leg 2 of the survey, which is represented with hollow circles on the map.

Before we reached the first station, we conducted a few safety drills.  The first was a fire drill and the second was an abandon ship drill.  The purpose of these drills is to make sure we understand where to go (muster) in case of an emergency.   For the abandon ship drill, we had to grab our survival suits and life preservers and muster on the back deck.  The life rafts are stored one deck above and would be lowered to the fantail (rear deck of the ship) in the event of an actual emergency.  After the drill I had to test out my survival suit to make sure I knew how to put it on correctly.

On the way to our first station, we traveled through Whale Pass next to Whale Island, which lies off of the northern end of Kodiak Island.  While passing through this area, we saw a total of 4 whales spouting and so many sea otters, I lost track after I counted 20.  Unfortunately, none of my pictures really captured the moment.  The boat was moving too fast to get the sea otters before they flipped over or were out of sight.

secure for sea!
Last night’s warning about high seas in the early morning of September 6th.

A lot of people have emailed to ask me if I have been getting seasick.  So far, things haven’t been that bad, but I figured out that I feel pretty fine when I’m working and moving about the ship.  However, when I sit and type at a computer and focus my attention on the screen that seems to be when the seasickness hits. For the most part, getting some fresh air and eating dried ginger has saved me from getting sick and fortunately, I knew about the threat of high winds last night, so I made sure to take some seasickness medication before going to bed.  After what we experienced this morning, I am sure glad I took some medication.

Everyone on board seems very friendly and always asks how I am doing.  It has been a real pleasure to meet the engineers, fisherman, NOAA Corps officers, scientists, and all others aboard the ship.  Since we have to work with the crew to get our research done, it’s wonderful to have a positive relationship with the various crew members.  Plus, I’m learning a lot about what kinds of careers one can have aboard a ship, in addition to being a scientist.

So far, I’ve worked two 12-hour shifts and even though I’m pretty tired after my long travel day and the adjustment from the Eastern Time Zone to the Alaskan Time Zone (a four hour difference), I’m having a great time!  I really enjoy getting my hands dirty (or fishy) and processing the fish that we bring in from the trawl net.  Processing the haul involves identifying, sorting, counting, measuring the length, and freezing some of the catch.  The catch is mainly composed of different types of fish like pollock and eulachon, but sometimes there are squid, shrimp, and jellyfish as well.

One of the hardest parts of the trip so far is getting used to starting work at noon and working until midnight.  We have predetermined lunch and dinner times, 11:30 AM and 5:00 PM respectively, so I basically eat lunch for breakfast and dinner for lunch and then I snack a little before I go to bed after my shift ends at midnight.  As the days go by, I’m sure I’ll get more used to the schedule.

During one of our trawls, we found a lanternfish.  Lanternfish have rows of photophores along the length of their bodies.  Photophores produce bioluminescence and are used for signaling in deep, dark waters.  The fish can control the amount of light that the photophores produce.  Lanternfish belong to the Family Myctophidae and are “one of the most abundant and diverse of all oceanic fish families” (NOAA Ocean Explorer).
