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.
Mission: Long Line Shark/ Red Snapper survey Leg 1
Geographic Area: Southeastern U.S. coast
Date: August 29, 2018
“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.
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.
Male Great Hammerhead 10. 5 ft.
Great Hammerhead cephalofoil
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 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.
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 on long line
Sandbar Shark in cradle
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.
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!
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
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.
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.
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.

Science and Technology Log
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 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.
When all measurements are complete, a tag is then placed at the base of the first dorsal (top) fin. First a small incision is made, and then the tagger pushes the tag just below the skin. The tag contains a tracking number and total length to be taken by the person who finds the shark next, and a phone number to call NOAA, so the data can recorded and compared to the previous time data is recorded. The yellow swivel tags, used for smaller sharks, are identical to ones used in sheep ears in the farming industry, and are placed on the front of the dorsal fin. The measurements and tag number are collected on the data sheet for each station. The data is input to a computer and uploaded to the NOAA shark database so populations and numbers can be assessed at any time by NOAA and state Departments of Natural Resources.
The shark is then unhooked safely by a skilled fisherman while the other two are keeping the shark still to protect both the shark and the fishermen from injury. The cradle is then slowly lowered by crane back into the ocean where the shark can easily glide back into its environment unharmed. The cradle is then raised back on deck by the crane operator, and guided by the two fishermen. All crew on deck must wear hardhats during this operation as safety for all is one of NOAA’s top priorities. This process is usually completed within 2 minutes, or the time it took you to read this post. It can happen many times during a station, as there are 100 hooks on the one mile line.
It is amazing for me to see and participate in the long line fishing process. I find it similar to watching medical television shows like “ER” where you see a highly skilled team of individually talented members working together quickly and efficiently to perform an operation. It can be highly stressful if the shark is not cooperating, or the conditions aren’t ideal, but each member always keeps their cool under this intense work. It’s also amazing to see the wealth of knowledge each person has so when an issue arises, someone always knows the answer to the problem, or the right tool to use to fix the situation, as they’ve done it before.

While our main mission aboard the NOAA Ship Oregon II is to survey and study sharks and red snapper, it is also very important to understand the environmental conditions and physical properties of the sea water in which these animals live. The CTD instrument is used to help understand many different properties within the water itself. The acronym CTD stands for Conductivity (salinity), Temperature, and Depth. Sensors also measure dissolved oxygen content and fluorescence (presence of cholorphyll).
Conductivity is a measure of how well a solution conducts electricity and it is directly related to salinity, or the salt that is within ocean water. When salinity measurements are combined with temperature readings, seawater density can be determined. This is crucial information since seawater density is a driving force for major ocean currents. The physical properties and the depth of the water is recorded continuously both on the way down to the ocean floor, and on the way back up to the surface. There is a light, and a video camera attached to the CTD to provide a look at the bottom type, as that is where the long line is deployed, and gives us a good look at the environment where our catch is made. These data can explain why certain animals gather in areas with certain bottom types or physical parameters. This can be particularly important in areas such as the hypoxic zone in the Gulf of Mexico. This is an area of low oxygen water caused by algal blooms related to runoff of chemical fertilizers from the Mississippi River drainage.
Ready to deploy the CTD
Calibrating the CTD
The CTD instrument itself is housed in a steel container and is surrounded by a ring of of steel tubing to protect it while deployed and from bumping against the ship or sea floor. Attached water sampling bottles can be individually triggered at various depths to collect water samples allowing scientists to analyze water at specific depths at a particular place and time. The entire structure is slowly lowered by a hydraulic winch, and is capable of making vertical profiles to depths over 500 meters. An interior computer display in the ship’s Dry Science Lab profiles the current location of the CTD and shows when the winch should stop. We have found this to be a tricky job, during large wave swells, as the boat rocks quite a bit and changes the depth by a meter or more. The operator must be very careful that the CTD doesn’t hit the ocean floor too hard which can damage the equipment.
The data collected while deployed at each station is instantly uploaded to NOAA servers for immediate use by researchers and scientists. The current data is also available the general public as well, on the NOAA website. Once safely back aboard the Oregon II, the CTD video camera is taken off and uploaded to the computer, The CTD must be washed off and the lines flushed for one minute with fresh water, as the salt water from the ocean can damage and corrode the very sensitive equipment inside. The instrument is also calibrated regularly to ensure it is working correctly throughout all legs of the long line survey.
I am having such a great time during my Teacher at Sea experience. In the 9 days aboard ship so far, we have traveled the entire coasts of Mississippi, Arkansas, Florida, South Carolina, and North Carolina. Never in my life did I think I would get an opportunity to do something like this as I’ve dreamed about it for decades, and now my dreams have come true. I’m learning so much about fishing procedures, the biology of sharks, navigational charting, and the science of collecting data for further study while back on land at the lab. I can’t wait to get home and spread the word about NOAA’s mission and how they are helping make the world a better place, and are advocating for the conservation of these beautiful animals!

During my NOAA Teacher at Sea experience, I have truly been inspired and impressed by how many important roles of our operation on the Oregon II are fulfilled by females. One of the most important crew members is Ensign (ENS) Chelsea Parrish who is one of our OOD’s. or Officers of the Deck. I think her story will inspire my daughter and female students to aim high for their future!
As a young child, Chelsea was inspired by her father who spent 20 years in the US Navy. She loved hearing stories about his role working aboard Navy submarines, and all of the interesting things one must do to work below the sea. After high school she attended the Savannah State University, in Georgia. She was able to train aboard the R/V Savannah where she learned about biological, chemical, physical, and geological oceanographic studies in estuaries and continental shelf waters in the southeastern US Atlantic and Gulf coasts. She earned her Bachelor degree in Biology, and received her Masters degree in Marine Science. While she didn’t need her Masters to get into her field, she knew that in the long run it would put herself above others in a highly competitive field and would be an advantage in the future.
A year into graduate school, she attended a conference, where she learned about the NOAA Corps. The NOAA Corps is one of the seven federally uniformed services of the United States, and is made up of scientifically and technically trained and commissioned officers. It was there that she met Lt. Commander Adler, whom she kept in contact with. Just a short time later, she was called for an open opportunity to join the NOAA Corps. She had 17 weeks of real world training at the Coast Guard Academy for Officer Candidate School (OCS). It was there that she learned how NOAA is different than the US Navy. The Navy focuses on various military actions, while NOAA Corps focus is on science and their motto is: “Science, Service, Stewardship”. It was then Chelsea knew she came to the right place to fulfill her professional goals.
After graduating from training, she earned her Officer of the Deck qualification aboard Oregon II in September, 2017. She will be aboard completing her assignment in January, 2019. Chelsea has many important duties to perform on the ship, including steering the ship. This entails following the chart that the CO (Commanding Officer, or Captain) has planned out to fulfill the mission of the ship. In our case the mission is long line fishing of Red Snapper and Sharks at many stations along the southeastern US and the Gulf of Mexico. While the CO is off duty, she must keep him informed of any changes that need to made to the Navigation trackline to ensure there is a safe navigational watch during her shift, which is normally 4 hours at a time.
The most common thing to happen that happens to create a change in course is foul weather, but there are many unforeseen events as well. Chelsea must study reports from the US Coast Guard which let her know various events happening in the region we are sailing. This can be other ships performing science missions, merchant navy ships of other countries in the area, oil drilling operations, or in our case yesterday, live ammunition firing exercises by the US Navy.
Chelsea is also the environmental compliance officer aboard the ship, and she must follow specific rules set up by the EPA (Environmental Protection Agency) to ensure Oregon II is environmentally responsible while at sea. She must be sure there aren’t any issues with fuel, garbage, or any other foreign substance being put in the ocean while at port, or at sea. She also keeps a recycling log to track all activity and incidents that occur. Chelsea also runs the ship store and keeps track of all the items to be sold to the crew and volunteers aboard the ship.
Finally, Chelsea is the go- to rescue swimmer aboard Oregon II, and is the first to jump into the ocean if there is someone overboard to be retained from our ship, or another at sea near us. I saw her in action during our drills at the beginning of our trip and I was impressed at how quickly the crew launched our rescue boat, so Chelsea could rescue our life ring that acted as our “person overboard”. She also took a 3 week class to get certified as a NOAA working scuba diver. This certification allows her to be in the ocean to find, and/or fix any issues we have with the ship while at sea that can’t be fixed from the deck or rescue boat. She is certified to dive down to 130 feet below the surface.
It certainly is impressive how much Chelsea has accomplished in her 28 years. I hope this post inspires all my students, but especially the girls to go out into the world and do anything they can dream of, as that is exactly what Chelsea did. When her time aboard Oregon II is over, Chelsea plans to be a Cetacean Photogrammetry Specialist in La Jolla, California. She will be getting to get her FAA drone license to fly hexacopter drones from ships. Her duties will be to find, count and track marine mammals such as seals, dolphins, and whales. She said she loves helping NOAA fulfill their mission of helping marine animals and data collecting to further the study of these creatures and helping ensure their survival in the future.
Now that I am almost a week into the survey, I am starting to fall into the rhythm of working on the ship. The 12 hour work days are certainly long, but we do get breaks between stations to rest, converse, and prepare for the next run. If it’s a good station and we haul in a lot of catch, we often spend time talking about each of the things we caught and become like kids on Christmas if it’s something new and interesting. We also spend time logging all the data we collect into the computer for later research on land.
We have seen just about all the different weather scenarios you could imagine, and have endured bright, 93 degree cloudless days, and windy days with 6 foot waves and pouring rain. We’ve had to call off a few stations until our way back south down the coast due to poor conditions, because on all NOAA ships, the motto is “Safety First”. The real trick is working during the big wave conditions and learning how to function as a human being while the boat is rocking and rolling all about for the entire day. I’m getting better at anticipating where my next step will land and compensating for the constant shifting gravity under my feet. It will make walking on earth again seem so easy!

Weather Data from the Bridge: Wind speed 11 knots, Air Temp: 27.6c, Visibility 10 nautical miles, Wave height 1 foot
Science and Technology Log: As we move through the Gulf of Mexico headed to our first research station, I didn’t have a job most of the day, so I sought to find out more information about what makes the great Oregon ll function to serve it’s crew of 28. One of the Engineers kindly offered me a tour of the engine room to see what lies below the service decks.
The ship is powered by twin 900 horse power engines that turn the propeller shaft up to 12 knots. When sailing between work stations, generally both engines are used, and when long line fishing begins, only one engine provides power as the ship moves around 2- 3 knots. The ship holds up to 70,000 gallons of fuel, and when both engines are running,1,000 gallons are used daily. There is also a bow thruster engine near the front of the ship that is much smaller and helps with finer movements at the dock, in stations, or when seas get rough.
There are 2 large electrical power generators that provide electricity to the ship for the multitude of research computers and data collectors. While out at sea, Oregon ll is always tracking weather data, water quality, live radar from above the ship, and also sonar from below the ocean. The generators also provide power for all the creature comforts you would need in any living environment, as this ship is the crew’s home during each leg of the trip. At times when less power is needed, one generator is shut down to conserve energy for later use.
The Oregon ll also provides it’s own clean water for equipment and human consumption. The Water Purification System uses Reverse Osmosis to take salt water from the ocean and turn it into potable water to wash, cook, clean with, and drink. A Reverse Osmosis System uses high pressure and pushes impure water through a semi-permeable membrane which allows clean water through the membrane, while allowing impurities (such as salt, bacteria, and sediment) to be blocked from coming through, and discharges the impurities back into the ocean.
Personal Log: I am having a great time getting to know the crew and their many jobs around the ship, and how each one affects the other. This symbiotic relationship is the heart of what makes every mission successful. There are the Ship’s Officers who chart the course, drive the ship, and oversee all Crew Members. The Deck Department makes sure the work areas are safe and equipment is working correctly. The Fishermen are in charge of the process of the Long Line Survey, from preparation, to process, to clean-up. The Engineering Department makes sure the interior of the ship and it’s equipment are functioning properly, which is a very wide ranging. I certainly wish I had these guys around my house during those tricky repairs!
The Steward Department is in charge of ordering, cooking, serving, and cleaning up of all meals for the crew. Finally, the Electronic Department has the complicated job of installing, operating, and fixing any electronic equipment. Let me tell you, there are miles of wires running through this ship and all of it is used to make the mission successful. All data is continually collected, and preserved for later study. Some of the water and weather data is uploaded to the NOAA website for the public’s use as well.
I really enjoyed hearing the wide ranges of places in America the Oregon ll crew come from. It is also impressive to hear the various places all around the world they’ve sailed before joining NOAA, and which other NOAA ships they’ve been crew members on. The diverse experience each crew person has in their field has really helped the mission many times over since I’ve been here. One thing I know is true is that each of them is happy to tell you about their families, and how much they love them and miss them while they’re away. Many of them have long seasons away from the ones they love, and count the days until they can come home.
Fun Fact: NOAA Ship Oregon ll turned 50 years old last year, and was honored for making the half century mark of service. It was built in 1967, right in it’s home port of Pascagoula, Mississippi

My name is Stephen Kade, and I’m a middle school art teacher at OL Smith Middle School in Dearborn, Michigan. I’ll be joining the crew of the NOAA Ship Oregon II for a few weeks this summer as part of the 2018 NOAA Teacher at Sea program. We’ll be starting in Pascagoula, Mississippi, and working along the Gulf of Mexico to the Florida Keys, and then moving north in the Atlantic to Cape Canaveral, Florida. We’ll be long line fishing for red snapper and sharks to research. I can’t wait to get aboard and find new ways I learn learn about these fish, and how I can use art to help bring awareness to, and advocate for, all threatened and endangered sea creatures and their ocean environments.
This opportunity is a great chance for me to fulfill a lifelong dream of working with sharks as a marine biologist (at least for a few weeks). As I study in preparation for the coming trip, I’ve realized the many hours of my life spent watching nature documentaries have paid off, as I’ve retained more knowledge of sharks than I thought! I’m also trying to study more about the crew and their roles on the ship, and all the working schedules and procedures to keep myself and other crew safe while we work. I’m finding this process is much like prepping for a lesson as a teacher and bringing many social and logistical resources together to create a strong foundation for learning while working.
I’ll be posting several times during the trip to keep everyone up to date with my findings during the adventure of a lifetime. This photo is of my art students and me in class, after creating their Endangered Animal Awareness Posters for our first annual Night of the Arts 2018.
