NOAA Ship Oscar Dyson in Kodiak, Alaska
Science and Technology Log
Oscar Dyson is one of NOAA’s fisheries survey vessels. It was commissioned in 2005 and its home port is Kodiak, Alaska. The ship was named after the Alaskan fisherman Oscar Dyson who was an activist for improving the fishing industry. He passed away in 1995. The purpose of Oscar Dyson is to collect data on marine life and ecosystems primarily in the Bering Sea and Gulf of Alaska. Most of the research has been focused on the management of Alaska pollock, which is the largest fishery by volume in the United States. The ship houses a crew of up to 24, which includes NOAA Corps officers, engineers, deck hands, survey technicians, stewards, and electronic technicians along with up to 15 scientists. They all work together to make daily operations on the Oscar Dyson a success.
The 208 ft. long Oscar Dyson runs on 4 super charged diesel engines. The engines are designed to produce up to 3 megawatts of electricity a day. The alternating current is converted into direct current in order to power the two propulsion motors. Oscar Dyson’s engine room is fully automated and will add or remove diesel generators based on load demand. Oscar Dyson has a cruising speed of 12 knots and a range of 12,000 nautical miles.
I was pleasantly surprised by how spacious my accommodations are on Oscar Dyson. I am in a 4-person room but have only 1 roommate. Her name is Alex Padilla. She is an ocean engineering graduate student from University of New Hampshire interested in studying the acoustics of bubbles. Our room has bunk beds on both sides of the room, a desk, multiple storage lockers, a toilet & shower, and a large wall mounted TV with movies and Direct TV.

Just down the passageway from my stateroom is a crew lounge where we can gather and watch movies. There is a mess deck (cafeteria) that serves three meals a day and is open 24/7 for soup, salad, and snacks. Oscar Dyson has a variety of labs that I will cover in future blogs. I was fortunate to have 3 days on the ship before our departure and have become somewhat familiar with the layout of the ship.

I am very excited and grateful to be a 2017 National Oceanic and Atmospheric Administration (NOAA) Teacher at Sea (TAS). The TAS program has existed since 1990 and their mission is to provide real world research experience for kindergarten through college-level teachers. The application process opens in the fall and teachers are notified in the spring if they are selected. This year there are 29 teachers who have either already sailed or, like me, are about to embark. Check out the TAS FAQ’s page to learn more about the program: NOAA TAS Frequently Asked Questions.
Where is Kodiak, Alaska?
Video Above: Google Earth view of where I will be starting my Teacher at Sea cruise.
Kodiak, Alaska is a small fishing village on Kodiak Island. There are two ways to get to the island – by air or by sea. I will be flying to Kodiak from Anchorage and will board the NOAA vessel Oscar Dyson. This is my 3rd time visiting Alaska but my first time at sea. I got engaged in 2014 on top of the Harding Icefield in Kanai Fjords National Park.
Having just arrived home from one of the driest deserts in the world (Atacama, Chile) I am reminded that the desert is my home. I have lived in Phoenix, Arizona, far away from the sea, for the past 25 years. I love the warm sunny heat of the desert but not when it gets over 110 degrees. So I am looking forward to a change in weather and scenery. Alaska is beautiful in the summer with really long days of sunlight. I am hoping to see a whole new view of this rugged wild state during my three seeks at sea. I just hope I don’t get sea sick!
Science and Technology Log
I have three objectives for my TAS adventure. They are:
To be able to describe how and why we research pollock.
To be able to describe life at sea on a NOAA ship and the careers associated with the NOAA Corps.
To be able to describe navigation techniques and how they have changed over time.
My ultimate goal is be able to bring this information back to the classroom. I have always been fascinated with navigation. Reading maps is an important part of being a geologist and I wonder how similar or different it will be at sea. As a geology student I leaned how to map the contact between two rocks. So I am really curious to learn how you chase fish in the sea. Please feel free to leave a comment below if you have any questions or want me to investigate something while at sea.
Personal Log
When you apply to the TAS program they ask you which type of research cruise (hydrographic, oceanographic, or fisheries) you would prefer. I checked both hydrographic or oceanographic because of my geology background. I teach about weather, climate change, and have always been curious about how we map the ocean. So I am a little nervous about being on a fisheries cruise for 3 weeks. But I am also excited about the opportunity to learn and explore something completely outside my norm. My family finds this amusing because as a kid all I did was fish.
Me fishing around 9 years old.
Here is a photo of me fishing at age 9. During the summer time, while living in New Hampshire, I use to fish everyday. But around the age of 12 that changed. I became less interested in the biological world and more into the physical world (geology, physics, chemistry, etc.). I stopped fishing and haven’t picked up a pole in over 35 years. Even when I was into fishing as a kid, I still didn’t like touching them. Now I will be spending 3 weeks studying Alaska pollock (walleye pollock) off the coast of Alaska. As a result of this experience, I wonder if the girl in this photo will rise like a phoenix and fall back in love with fishing. Hmm – at the moment I’m thinking it’s a 50-50 chance! What do you think? Leave me a message in the comments below.

Controlling the DropCam requires concentration.
We have been in the Shumigan Islands, which are a group of 20 islands in the Aleutians East Borough south of the mainland. It has been beautiful. In between doing DropCams ( I even got to take over the controls once!) and fishing, we have been able to enjoy a few moments outside taking in some of the amazing views. And then, it’s back to fishing!
The Fish Lab team (Ethan, Abigail, Katy or Meredith, and I) are becoming very efficient in our roles in the lab. I am getting much quicker at identifying the sex of fish and measuring their lengths. It is really nice to have an efficient routine dialed in.
I had mentioned before that I wanted to go into detail about how the actual “fishing” works. First, and foremost, I am impressed with the amount of teamwork that is required to do this. There are about 12 people needed at various positions to make a fishing operation happen. There are people in the Acoustics Lab, the Bridge, on the deck, and of course, in the Fish lab itself. I am reminded again about how important clear and concise communication is. Everyone talks to each other with radios and ensures that all steps of the process has been heard.
Making the Decision to Fish
The scientists spend a lot of time in the Acoustics lab (or The Cave). This is where they receive the feedback from the echo sounders in the water. The monitors show images of backscatter that give the scientists a “picture” of what is going on in the water. When they see something that they would like to fish, they call up to the Bridge and let them know that, “We’re going fishing!”.

Deploying the Net
There are many steps involved in getting the net into the water. A survey technician will operate the winch. There are usually two deck hands to ensure that everything is deployed properly. They always make sure that the pocket net, which catches smaller marine life, is secure and closed. The CamTrawl, FS70 (or “turtle”), SBE39, and ITI must also be attached to the net. The CamTrawl takes pictures of everything coming into the net and the “turtle” takes a sound picture of the area in and around the net opening.

Haul Back
Once the science team decides that they have what they would like in the net, they announce that its time to, “Haul back!” in the radio. At this point, the winch operators and Deck hands start bringing in the net. The contents of the pocket net are given to the scientists for identification. The scientific equipment are also removed and downloaded. The fish that are in the net are brought over to a bin next to the Fish lab with a crane. The nets are then carefully maneuvered back onto the net reel.

Getting Ready
Once Abigail, Ethan, and I see that they are “hauling back”, we start getting ready for the Fish Lab. We get dressed, put on music, and get out the necessary equipment. The Fish lab is definitely wet, so we want to make sure that we have proper coverage! If there is some extra time, we will see how long we can hold a plank for. We are up to 2 minutes!

Fish on the Table
Once the fish are placed in the bin by the crane outside of the Fish lab, we can control how fast it is brought onto the belt by the door. First, we separate anything that is not pollock from the catch. We identify and record this data. Then, we weigh the pollock. We separate the males and females. The males go into the “bloke” bin and the females go into “sheilas” bin. From there, each fish is measured. The goal is to get a total of about 250 fish lengths. Sometimes, there are more females than males, and sometimes there are more males than females. The length of each fish is recorded with an Ichthystick. This is a fish length board designed to electronically measure and record the length of each fish. The Ichthystick was designed by the personnel at NOAA. After the lengths are taken, we take anywhere from 15-50 pairs of otoliths from the pollock. The otoliths are preserved and used to determine the age of the fish. Finally, when all the fish have been lengthed and otoliths taken, we clean up. This does take some time, as no one wants a lingering fish smell around. There are numerous sprayers around that are used to clean every nook and cranny of the lab. Then, we clean ourselves up and wait for the next haul!

Personal Log
Though we have been working 12 hours shifts, we do still manage to enjoy some of the spectacular views. I am amazed over and over again at how stunning and diverse the landscape is here. Sometimes the hills are covered in lush green, and sometimes there are snow covered mountains. When we can find a moment, we will just stand out on deck and take it all in. It truly is breathtaking.

Interview with Abigail McCarthy
Scientist
What role do you play on this survey?
Abigail waits for the fish to come.
I’m the “fish lab lead” scientist, which means that I manage all the wet data collection. I make sure all the fish we catch in our different types of nets are sampled the right way, that we’re processing our catch and recording samples properly and that everyone in the fish lab is having fun! I also do a lot of support work for the chief scientist in the acoustic lab, judging our acoustic data from the fancy scientific fish-finders, analyzing those data and making sure they link up right with all the information from the wet lab. I make sure we’re putting the right scientific equipment on the net every time we fish, do the camera drops, make maps with the information we’re collecting and write code for our analysis and data collection software too.
What inspired you to pursue this as a career?
I sort of slid into this sideways. I majored in biology in college and wanted to be a doctor, then I got interested in plant biology midway through my undergraduate degree. After I graduated from college I did a couple of internship/ technician jobs at research stations where I studied rare plants, bird/ plant interactions, and a few other things. I branched out and worked on a couple of bird projects (Hawaii for rare forest birds and avian malaria, and Puerto Rico for parrots and hawks), and then I got a job working on coastal plant ecology at the Bodega Marine Lab. All my friends there were doing marine science and they were having so much fun and doing such cool projects, and I got even more curious about marine science. Then I saw an opening for a sea turtle job in Costa Rica. I speak Spanish well, and I had field experience, so I got hired there and worked on sea turtle nesting for almost a year, followed up by another sea turtle job with the Nature Conservancy in the Caribbean. All that nesting beach work made me wonder what was happening with turtles when they weren’t on the nesting beach, where did they go and what did they do in the open ocean?? So I applied to grad schools to study that question, and one of the best sea turtle biologists in the world is at Oregon State, where I went for my masters’ degree. If you find a cool project and a graduate professor who is good at getting funding, you can get paid to go to graduate school for marine biology. In grad school I spent a lot of time at the Hatfield Marine Science Center in Newport, OR, where I helped teach fisheries biology classes as part of my grad work. That got me interested in fish, fisheries data, and the way that science is used to inform the decisions that are made about commercial fisheries catch. So I applied to jobs at NOAA fisheries and got this one!
How long have you been working in this field?
I’ve been working at NOAA for 10 years, started grad school in 2003.
Are fisheries something that more people need to know about? Why?
Yes! Fish are the last truly wild source of food in the world. People can hunt to feed their families, but fisheries are the last place that huge quantities of protein come from a wild source without being farmed. If we don’t pay close attention to how many fish we catch, we run the risk of really screwing that up.
Do you think what do you is important?
I do. I think it’s important because we need to know not just what’s going on with fisheries, but also we have to do our best to understand the ocean and how the ocean is changing as there are more and more people on our planet. The ocean covers over 70% of the surface of the earth, at it’s deepest it’s more than 36,000 feet deep (you’d have to run 6.8 miles straight down from the surface at the deepest place in the ocean before you’d hit the bottom). There are whole ecosystems that we barely understand because it’s a lot harder to study things when you can’t see them or measure them directly. Think about how easy it is to look at other people,pets, trees, or buildings. It’s not hard to tell how many people there are in the classroom with you or how big the school is, but imagine trying to do that 1500 feet below the surface of the ocean! We get to figure out ways to study fish and fisheries without being able to walk right up to a fish and measure it’s length or ask it how old it is, and we use that information to understand how the fish populations change, which adds to the information we know about the ocean as a whole.
How much of the year do you spend at sea?
Between two and three months, depends on the year. Usually one or two cruises in the winter time and one or two in the summer, each about 3 weeks long.
What interests you most about the data collected on this survey?
I like to think about how it fits into the big picture; both how it compares to all the data we’ve collected in this area in the past, and how it compares to what the commercial fishermen see here. I like to make maps of the data we collect too. I think it’s a great way to visualize information. I’m also really interested in the data we’re collecting with our drop cameras- fish pictures are always cool.
What is the most challenging part of your job? The most rewarding?
There are a lot of rewarding parts of my job! One of the most rewarding is probably presenting the results of a completed survey- one where I sailed on the research cruise, was the lead analyst, and wrote the report (with lots of help from my colleagues, of course)- to the Plan Team. The Plan Team are the people who make the decisions about how many fish the commercial fishermen are allowed to catch each year, and I always enjoy telling them about our work, because we do excellent science and I’m proud of it.
Fisheries science, especially in Alaska, tends to be pretty male dominated. While I work with lots of remarkable people of both sexes with whom I enjoy spending time and from whom I have learned a lot, I wish I had more female colleagues. I also sometimes wish there were more women in leadership roles here.
What words of advice to you have for my students if they want to pursue a career in biology or the sciences?
Don’t let anyone tell you “No”. Take the math classes, take the biology and chemistry and physics when they’re offered, and if you don’t understand something, ask for help from anyone you can find. If you’re having trouble with math problems, find a teacher or a tutor to help you see it clearly. We always need more scientists- especially girls!

Science and Technology Log: Career Spotlight: I would like to introduce everyone to Ensign Hollis Johnson, one of the Junior Officers on NOAA Ship Pisces. She was kind enough to let me ask her a few questions about life at sea.
Ensign Hollis Johnson
Q: What is the role of a Junior Officer (JO) on this ship?
A: The primary duty of a JO is driving the ship. We are also the eyes and ears of the Commanding Officer (CO). We carry out standing orders, ensure ship safety, and also make sure the scientists are getting what they need for their survey work.
Q: Does this job description vary depending on the ship?
A: This is a generic fleet-wide description, and some ships are a little different. On hydrographic ships, there is more computer-based work with data collection. On fisheries ships, collateral duties are split amongst the JOs; for example, we have an environmental compliance officer, a safety officer, a movie officer, and a navigation officer.
Q: What do you like best about your job and being at sea?
A: I really like driving the ship. Few jobs offer this kind of an opportunity! I also like the fact that no two days are ever the same, so my job is a constant adventure. The best things about being at sea in general are the sunrises and sunsets, and the dolphins, of course.
Q: What do you find to be the most challenging aspect of your job and life at sea?
A: This job requires long hours. We can easily work 12-16 hour days, and while in port we still have to work some weekends. Because of this time commitment, we have to make sacrifices. But, we get that time back with our land assignments because there is more flexibility.
Q: When do NOAA Corps officers go to sea, and for how long do they stay?
A: After a 5-month training period, JOs are sent straight to sea assignments for 2 year periods. This can be extended or shortened by 6 months depending on what you are looking for in your next assignment. I extended my assignment at sea for 5 months so I could get my upcoming land assignment in California to work with dolphins for 3 years. After the land-based assignment, NOAA officers typically return to sea as operations officers, then back to land, then sea as executive officers, and so on. That is how you move up.
Q: What exactly will you be doing when you are on your next assignment in California?
A: The title of my position will be Cetacean Photo Specialist. I will be in La Jolla, CA, doing boat and aerial surveys, lots of GIS work and spatial surveys of marine mammal populations. I will participate in the center’s marine mammal stranding network. I will also be involved with outreach and education, which includes giving tours and presentations on scientific studies happening at the lab.
Q: Is life at sea different from what you expected?
A: Actually, it is easier than I thought it would be. I have always been a homebody and lived near my parents, I’m always busy here so time flies. I have internet and phone service so I still feel connected.
Q: Where did you go to college, and what degree did you earn?
A: I attended the University of Georgia, and earned a B.S. in Biology with a focus in marine biology.
Q: When / how did you decide to pursue a career in science?
A: When I was a kid I went to Sea World and fell in love with the whales and dolphins. I always loved animal planet. I also considered being a veterinarian for a while. I tried to be realistic because it is hard to land a career as a marine biologist, but I interned at a lot of places and made connections so I could do what I wanted to do.
Q: How did you find out about careers with NOAA?
In college, I took a summer course about marine mammals and toured a NOAA lab. About a year later, in June, my uncle saw the NOAA Ship Nancy Foster in port in Georgia, and I talked to someone on board about the work they were doing at sea. I immediately applied, interviewed, and was commissioned in January. It all happened very fast once I found out about it.
Q: You were one of the divers who recovered the missing trap this week. How long have you been diving?
A: I was certified to dive when I was 18. It is amazing, and something everyone should try. When I became an officer, the first thing I did was beg my command to send me to the NOAA Dive Center for training as a working diver.
Q: If a high school student is interested in a career like yours, what advice would you give?
A: Do a lot of volunteer work before you expect to get paid. You are investing in your future. If you want it bad enough you have to make sacrifices – but it will pay off. Make connections. If a marine biologist gives a presentation at your school, hang out after and talk with them. Ask for their email address and follow up. It’s a small world in marine research and networking is key.
Q: What is your favorite marine animal, and why?
A: I love thresher sharks and octopuses, but I’ll say Orcas. I’ve always found their species-wide diversity fascinating.
Personal Log:
There are so many people on this cruise who scuba dive and see amazing things below the sea surface. I have only snorkeled. I see dive certification in my future!

Science and Technology Log: Career Spotlight: I would like to introduce everyone to Danielle Power, the Survey Technician on NOAA Ship Pisces. She was kind enough to let me interview her today.
Editing map area coordinates in the acoustics lab
Q: What is the role of a survey technician (ST) on this ship?
A: The survey technician keeps track of scientific equipment and spaces. This includes calibrating sensors and maintaining and repairing equipment. When science parties are on the ship, the ST assists with data collection and oversees CTD operation.
Q: Does this job description vary depending on the ship?
A: Yes. On the Nancy Foster and other ships with big dive platforms, STs do a lot of diving and deck work. There are often two STs on board, each working a half-day shift. These STs do not work so intensively with fish. Hydrographic vessel STs deal with mapping and tide station installs.
Q: What do you like best about your job and being at sea?
A: My favorite thing about life at sea is that there are no bugs, and I don’t have to deal with allergies! I also meet awesome people on every cruise. Every trip is a little different, so I am always learning new things.
Q: What do you find to be the most challenging aspect of your job and life at sea?
A: Being at sea for a long time, all the time, is taxing.
Q: Is life at sea different from what you expected?
A: Yes. This job requires living with 20 other people in a confined space all the time, and it isn’t easy. I didn’t fully realize this back in college. I don’t have easy access to things I might want or need. I also have to give up certain aspects of social life. You can’t just take a day off, you have to take an entire leg of a cruise off (up to 2 weeks), which is a lot of money to not be making and a lot of work to be missing. So I have to miss some big events for important people in my life, like weddings and holidays.
Q: Where did you go to college, and what degree did you earn?
A: I graduated from Old Dominion University in Norfolk, Virginia. I earned a B.S. in biology with a concentration in marine biology.
Q: When / how did you decide to pursue a career in science?
A: In 6th grade, I went on a family vacation to Disney world. I went to Sea World, and it ignited my love for all things ocean. I have stuck with it ever since.
Q: If a high school student is interested in a career like yours, what advice would you give?
A: Work hard, and get a college degree that is relevant. Make sure you know that this is a job you truly want to do. Find internships and experience life on a ship before you commit. If you enjoy it, then make the most of the career and all of the opportunities that come with it.
Q: What is your favorite marine animal, and why?
A: An Octopus! Cephalopods are very intelligent creatures, and I love that they can blend into environments so well that they cannot be seen. They can change not just their color, but their texture. They are so interesting! They can go into small spaces, because they can fit anywhere their beaks fit and they use parts of their environment as tools.

Personal Log: I am blown away by all of the different jobs that need to be filled while out at sea. Working on a boat was something that I never even considered when I was in high school. The idea just never occurred to me, and I didn’t know anyone at the time who did anything like this. There are so many interesting career opportunities that exist, and new types of jobs will develop as needs and technology change over time.
