Science and Technology Log

Hake are not the only thing being studied during this mission. In the Chemistry Lab, there are a variety of ongoing tests. Every few transects, seawater is collected and tested for Harmful Algal Bloom (HABs). A vacuum pump sucks the sample through a 0.45um filter, which is then removed and placed into a test tube for microscopic study. The Southern California coast is currently dealing with a bloom toxic to animals. Scientists want to know if the bloom is drifting north. Blooms are a natural phenomenon, but human activity cannot be ruled out from having an impact.

A seawater pump connects to a software program that allows you to see images of phytoplankton being photographed in real time as they are sucked past the camera. Phytoplankton forms the base of the aquatic food web. They provide food for huge whales, small fish, invertebrates, and zooplankton. Plankton makes up 95% of life in the ocean, they generate half of our oxygen and absorb carbon. A sudden removal of phytoplankton would result in a collapse of aquatic ecosystems, and would accelerate climate change further.

The phytoplankton images are taken using a robotic microscope automating identification. The name of the artificial intelligence is Imaging Flow CytoBot (IFCB). Flow cytometry uses lasers to create both scattered and fluorescent light signals. These signals are read by photosensitive diodes and tubes, and then those signals can be converted electronically to be read by a computer. The data gathered enables ecosystem modeling, and can act as an early warning to toxic blooms.

Career feature

Steve stands at a line of computer screens and keyboards on the bridge. Through the bridge windows, we can make out blue water. Steve holds what might be an electronic pad in his left hand and a stylus in his right hand. He looks down, focused on his work. — Chief Scientist, Steve de Blois, on the bridge during a trawl.

Steve de Blois, Chief Scientist

Steve’s favorite thing about his job is getting out in nature, seeing, and photographing marine mammals. Even though the hours are long, the commute is short when you’re at sea! His educational background includes an undergraduate degree in biology from the University of Michigan, Ann Arbor; and a Master’s from Humboldt State University (now called Cal Poly Humboldt) in marine mammals. It was tough finding work after graduate school since working with marine mammals generally holds more appeal than fish, and thus more people are competing for a finite number of jobs. Once Steve secured a job at one of NOAA’s regional offices, he found out about other opportunities and ended up on a walleye pollock acoustic trawl survey in Alaska. This is where he had one of those National Geographic moments where the scenery is so stunning it touches you at your core. He has been with NOAA since 1990—the same year the Teacher at Sea Program began.

Steve’s advice for young people interested in ocean-related careers is to focus on getting your education. He states that getting a graduate degree (PhD and/or Master’s) will make you more competitive in the scientific community. However, he also advises, “get experience.” Nothing can compare to first-hand experience and there are many opportunities for volunteering in the field, in marine labs, and on ships.

During his leisure time, Steve prefers to fly his home-built plane (A Zenith CH 650), go scuba diving, and enjoy photography. When it comes to reading he prefers nonfiction. He has German heritage on his mother’s side and shared some personal history of family members surviving both World War One and World War Two. This part of his family tree has increased his interest in true tales about World War Two German fighter pilots. In his youth, he absorbed science fiction novels by Arthur C. Clarke and recalls enjoying Dune, by Frank Herbert. Recently, he read Rachel Carson’s classic The Sea Around Us and was impressed by its lyrical prose.

Steve has patiently taught me about how to detect hake sign on an echogram. Acoustically speaking, hake have a unique characteristic. The visualized pings usually show hake near the slope of the continental shelf, and they appear as a diffuse cloud of colored pixels, or as a “hakey snakey” line gently curving up and down. A calculation called NASC, Nautical Area Scattering Coefficient, makes an estimate of individuals in that defined area drawn by scientists.

The acoustic echogram has a color key representing the strength of return on what the sound waves bounce off. The color scale looks something like you’d see in an art room class teaching color theory. The weakest return is signified by a pale grey to dark, then a light blue shade into dark, the blue turns teal as it morphs into greens, then when yellow appears the scientists start getting excited. After yellow is orange, pink, then many shades of red ending with a deep magenta. The ocean floor appears as deep magenta. On Leg 2 the Shimada saw several very dense balls of fish; these fish are likely herring or sardines, species smaller than hake. The acoustic return from these very dense balls of fish is extremely high—their color in the acoustic software is easily deep red, almost brown.

The thin red lines in the echograms on the right represent the head rope from imaging by the SBE (Sea-Bird Electronics) camera, aka “the turtle.”

Taxonomy of Sights

Day 5. Bycatch highlights: Intact squid, Chinook salmon (also known as King salmon), and excited albatross following a record haul.

Day 6. More salmon, two kinds of rockfish, a Thetys vagina salp (more on the awkward name here), and a marine hatchetfish so small my camera found it difficult to focus on. Ethan Beyer, Wet Lab Lead, shared a trick to determine the difference between a yellowtail rockfish and widow rockfish (they look similar). The difference? Widow rockfish have a “widdle” mouth. Meaning, the mouth is smaller than the yellowtail’s (ha, ha). The two types of rockfish we caught were the widow and the shortbelly (Ethan says they make great tacos!) Speaking of tacos, the widow rockfish are due to make an appearance on our mess deck menu soon.

Day 7. Not much…

You Might Be Wondering…

What is the furthest you’ve been from shore?
To date (July 28th), an extension of transect 39 took us a total of 62 nautical miles from shore, which beat our extension record on Wednesday, July 26th. Leg 3 has extended more transects than Leg 2. The reason for extending a transect is to go where the fish sign is. The NOAA Fisheries protocol is to discover what the western extent is for schools of hake on that transect. So, they wait for at least one mile without seeing hake before ending the transect.

What is the deepest trawl you’ve made?
So far on Leg 3 we’ve gone 400 meters (about a quarter of a mile) to reach a target depth. Simply put, target depth is where the fish are estimated to be.

Floating Facts

Vocabulary

Bycatch – Some dictionaries call them unwanted creatures caught in the pursuit of a different species. NOAA however, thinks it worthwhile to catalog the biomass of these tag-alongs.

Biomass – The total weight (sometimes quantity) of a species in a given area or given volume.

One of these things is not like the others
Tow, Haul, and Trawl are used interchangeably in reference to fishing.
“Catch” is what we’ve caught in the net.

Survey Permits

You know how you ask permission at school and at home to do a thing? The hake survey requires a number of permits to conduct its research. A permit is an official document saying you have asked for and been granted permission.

NOAA’s Western Region office issues “Authorizations and Permits for Protected Species.” The protected species are salmon and eulachon, a thin silvery thing about the size of a herring. The permit dictates what you can (measure and weigh it) and can’t do (eat it) with protected species.

A state’s jurisdiction over ocean waters only extends three nautical miles from shore. The Oregon Department of Fish and Wildlife wants to know the number of all species caught off its coast. California’s Department of Fish and Wildlife issues a Memorandum of Understanding (MOU) along with a permit. The MOU calls out particular species they are interested in: longfin smelt, coho and chinook salmon.

Jenny stands in the wet lab holding a sizable salmon with two hands. She wears black gloves, black overalls, and a Teacher at Sea beanie. — I should be frowning – we don’t intend to be pulling salmon out of the water. However, their appearance does contribute to data about the health of their populations.

While fishing rarely ever happens in Alaskan waters during the hake survey, the Department of Fish and Game issues a permit that is shared with Canadian colleagues who may pursue hake further north. Waters defined by NOAA’s National Marine Sanctuaries have their own monitoring system and permit issuance. The hake survey passes through three sanctuaries in California waters and one in Washington (the Olympic Coast). Finally, the West Coast Region of NMFS (National Marine Fisheries Service) issues a permit and requires a record of all species caught in U.S. waters, so a grand total of sorts for all states involved.

Personal Log

Thursday was a huge improvement over the icky Wednesday ride. We made two successful trawls, and two trawls on Friday. Wet Lab Lead, Ethan Beyer, commented during fish processing on Friday, “I feel like I’m the world’s foremost expert on the visual maturity of hake. I look at a lot of hake gonads.” This was memorable.

Saturday dawned with too much fishing line in the water to do anything so we waited until we moved past it before dipping the net in. We did squeeze in a catch before lunch, but it produced exactly one hake among the usual lanternfish and pyrosomes. Disappointing for the science crew.

Note: In an earlier post I referred to lanternfish as “lampfish,” which is incorrect. I’ve also been calling Dramamine “dopamine” for some reason. I’ll blame it on the mild disorientation that is caused by floating around on the ocean.

My Daily Routine

I wake around 0600 and sometimes make it up to the flying bridge to see the sunrise, but usually go up regardless before breakfast to view the morning light. I stop in at the acoustics lab to sit at my workstation, blog a bit, and see what hake sign there is on the echogram (software visualization of what lies beneath us). Breakfast is served at 0700, then I return to acoustics to stay up to date on when we’re going fishing.

When you hear, “Fishing, fishing, fishing,” on the radio you know it’s almost time for the marine mammal watch. Marine mammal watch happens on the bridge, and I continue watching for a while even after the watch ends. I’ll stay up there for most of the trawl until I hear, ”Doors at the surface.” (More on the stages of a trawl next time.)

Next, I’ll go to the “ready room” in the wet lab where boots and fishy rubber overalls are stored. Blog post three walked you through what we do in the Wet Lab once the catch has been dumped in the crate. Processing species takes us into lunch hour at 1100.

A second trawl after lunch, and assuming the catch is decent, processing will take us to dinner. I have down time after dinner, watch the evening light if the weather is amenable, then return to acoustics for more blog time. I’m in bed somewhere between 2030 and 2230.

While there is a general routine, no day is exactly alike. On Saturday I assisted Ethan with collecting sea water from a vertical net dipped by a crane to 100 meters. Scientists will look at the plankton, krill, and other small species to determine stratification and measure abundance.

Librarian at Sea

“It is a curious situation that the sea, from which life first arose should now be threatened by the activities of one form of that life. But the sea, though changed in a sinister way, will continue to exist; the threat is rather to life itself.”― Rachel Carson, The Sea Around Us

The cover of Rachel Carson’s book, The Sea Around Us, appears on the wall of the dining room at Sylvia Beach Hotel where I stayed prior to the departure of leg three. Her poetic approach to scientific insight continues to inspire readers. The book I brought with me on the ship does something similar. In How Far the Light Reaches, author Sabrina Imbler blends personal memoir with profiles of ten sea creatures. Imbler attempts to keep metaphors and personal (human) parallels at a distance from the scientific integrity of species. Both titles are recommended reading.

Hook, Line, and Thinker

When I was a kid, my Dad sometimes sang Gordon Lightfoot’s ‘Ode to Big Blue’ as a lullaby before bed. It’s one of the only songs I know all the lyrics to, although sometimes I scramble the verses up. I think it was my first exposure to the tension between commerce and the sustainability of natural resources. The sixth verse says,

Now the gray whale is run and the sperm is almost done
The finbacks and the Greenland rights have all passed and gone
They’ve been taken by the men for the money they could spend
And the killing never ends it just goes on

Herein lies another ethical debate on balancing preservation, economics, and the needs and wants of Homo sapiens. The song celebrates the natural wonder of whales alongside the biting reality of human enterprise.

In April 2023 NOAA released a 2022 Status of Stocks report. Data displayed overfishing status of 490+ stocks managed by NOAA.

a NOAA Fisheries infographic showing two pie graphs in the shape of fish silhouettes. the first is labeled 355 Stocks with Known Overfishing Status. This graph shows that 93% are not subject to overfishing (331 stocks) while 7% (just the tip of the tail of this snapper-shaped fish) are subject to overfishing (24 stocks). The other graph is labeled 249 Stocks with Known Overfishing Status. It shows that 81% are not overfished (201 stocks) while 19% (a little more than the tail of this tuna-shaped fish) are overfished (48 stocks).

NOAA Fisheries assistant administrator, Janet Coit, said in the Status of Stocks news release, “Managing fisheries sustainably is an adaptive process, relying on sound science and innovation to conserve species and habitat, and meet the challenge of increasing our nation’s seafood supply in the face of climate change.” NOAA Fisheries priorities for fiscal year 2023 are full of words like: sustainability, resilience, mitigate, adapt, diversify, ensure equity, safeguard, propel recovery, conservation, protect, and restore. NOAA continuously strives to balance the scales between conservation and consumption.

What are the ethical concerns that should guide economics?
Is it possible to view the ocean other than as a natural resource?
Is that view in fact imperative to the sustainability of life on Earth?

Waves: 2-4 ft.

Science and Technology Log

Each day is started and then ended with a water sample from the ocean. The technology is called a CTD, but the procedure would be called a CTD cast (as if we were casting it in the ocean). CTD stands for conductivity, temperature, and depth. The CTD consists of a collection of electronic instruments that measure the properties of the water, including a laser that checks the clarity of the water. Sampling water bottles are connected to a metal frame called a “rosette”. This information on water characteristics is important to both the scientists and the survey mapping team that use cameras and sonar. This information lets them know how well the clarity of the water is and the speed of sound that helps with the depth finders and sonar.

The apparatus containing the conductivity, temperature, and depth probe sits on the deck of NOAA Ship Pisces, awaiting deployment. — CTD used to check water quality, conductivity, temperature, and depth.

Vocabulary Check

What is Conductivity?

Conductivity is a measure of the ability of water to pass an electrical current.

What is Salinity?

Salinity is the dissolved salt content of a body of water and is a strong conductor of water.

So why is it important for scientist to know what each of these are?

The higher salinity the water is, the higher the conductivity of electrical currents.

Temperature also plays a role in the density. Knowing each of these is important because it lets the scientists know the water quality at different depths so they can make adjustments to their cameras and sonar.

Jack Prior, Chief Scientist

Jack is a pretty “chill” guy, and I have enjoyed watching him in action the past few days. Jack is the field party chief of this mission which involves everything from planning the trip, to deciding the daily sampling locations, deploying cameras, mapping, and figuring out what to do when things go wrong. Jack is in charge of planning and submitting the protocol for the entire mission and also is responsible for the end reports of the mission. You will find Jack on this leg sitting behind multiple computers regulating and keeping a watchful eye on all of the important information regarding this mission. Jack attended the University of West Florida to get his degree in marine biology.

Jack sits at a computer desk with multiple monitors. He smiles at the camera, his right hand giving a thumbs up. — Chief Scientist Jack Prior

Student Question of the Day

Whenever I get a chance, I ask random crew members questions that my students back home were curious about. Here is how Jack answered some of the students’ questions.

Konnor, Nichole, Lillian ask: What degree do you have and what all is needed to do your job?

Jack started his major in biology and had originally planned on going on to be a pharmacist, but then moved to Florida where he ended up getting his degree in marine biology instead. Jack continued to also get his Masters at the University of West Florida, too. Jack changed his career path because he enjoyed marine life. Volunteer work is crucial to get experience, and can benefit you on becoming more diverse when it comes to getting a job in marine biology.

Alyson asks: What would be your dream job?

Someday Jack wants to explore the seafloor in a submarine.

Blake, Sailor, Lilli, Jenna ask: What is your favorite food on the ship?

Taco Tuesdays seem to be a huge hit on the ship, as well as Friday pizza day.

Auburn, Ashton M., Karson, Liam: What would you consider to be the coolest marine life you have seen?

Seeing large diverse reef habitats is what Jack says he finds the most interesting, especially uncommon invertebrates that you’d never see on the beach.

Jaxon and Dwight: Can you be on the ship if you have health issues and what happens if there is a medical emergency?

The ship is a pretty confined space with steep stairs, uneven footing, areas you have to be able to step over, and have the ability to carry heavy weight. If there is ever a medical emergency, the ship works alongside the United States Coast Guard to get them the help they need. However, the ship is great working with all issues and plans accordingly to those who may have special diet restrictions.

Personal Log

Well, I will say that I am getting better at having my sea legs but that is still a work in progress. I have really enjoyed getting to understand the life on this ship, and I am just amazed at how diverse everyone is and yet still make this an amazing environment. It has taken me a few days to get the hang of where things are and to get out of my comfort zone to ask what I feel like has to be a million questions about everything. I have really enjoyed getting to hear and learn about the crew’s background and how they ended up on NOAA Ship Pisces. I greatly appreciate their willingness to answer my questions, even though I am sure I am in their way at moments. Everyone has a job to do and work different hours and shifts. It is great to see how they all respect each other’s space and sleeping hours.

There is so much science around me that I never knew existed, and I am shocked on how much technology is actually being used and heavily relied upon. Today was the first day the waves were calm enough that I was able to go out on the stern (learning names of different areas of the ship) to work on the blog and soak up a little bit of Sun. It was nice to be able to get some fresh air. The food has been amazing on the ship. I love how everyone is so courteous by thanking the cooks, as well as cleaning up after themselves before leaving the mess. The mess is the area in which we eat and the kitchen is called the galley. It has taken me a few days to understand the boat “lingo” but I am starting to catch on. The stairs are pretty steep, and everyone on board says to use 3 points of contact when walking. This is so that if they hit a wave while walking you are more stable. I could definitely see this being an issue going up and down the stairs. The doors are super heavy and I am still learning how to get those twisted and sealed tight the first time I close it (I am getting there).

A view of the mess: that is, the ship's the dining area. At the moment, it is unoccupied. There are five long tables, bolted to the floor, covered in blue vinyl or plastic table clothes. Black chairs surround each one. The chair's legs are all capped in cut-open tennis balls. The tables are supplied with condiments and paper towel holders. A large television screen mounted on the wall shows a football game. — The mess where we eat. It is spotless and a great size to fit everyone on board.

Science Log

On Wednesday, August 31, 2022, NOAA Ship Oregon II departed Cape Canaveral and started a path along the Florida coastline headed to the Gulf of Mexico. All of us took another Covid-19 test before departure to keep everyone safe. We had to wait for 17,000 gallons of diesel fuel to load the vessel. I was surprised about the amount of fuel needed for our journey! Although my shift begins at 12pm, I have time to get adjusted since we haven’t made it to the 1st location. I included my students in the interviews with several shipmates. Heather Moncrief-Cox, Senior Research Associate, and Jim Patterson, Fisheries Biologist, sat with me while I logged into Google Meet during my 9th grade Algebra Math class. They seemed happy to answer the questions shown below and were patient with the students. Mrs. Ashanti Raymond, teacher at McNair High School, did an excellent job monitoring the students working while they took their turn asking questions in front of the screen.

On Thursday, September 1, 2022, the students from my Coordinate Algebra & Pre-Calculus classes interviewed Chuck Godwin, Lead Fisherman, and Collin Lynch, Chief Electronics Technician. Their careers & lives are quite interesting! We found out more information about the logistics of fisheries surveys, different careers, education & certifications. I appreciate them taking the time to talk to us! This experience helps me and others understand the purpose of research, safety rules, and how everyone’s part is important!

Table titled: Interview Questions for Teacher at Sea Program: Chuck Godwin, Jim Patterson, or Heather Moncrief-Cox. Table includes 18 questions, such as "When did you realize you wanted to pursue a career in science or an ocean career?" and "What are your normal job duties?" — **Interview Question suggestions for the students at McNair High School**

The carousel of pictures was taken while students logged into Google Meet to interview my shipmates. Many of the students took notes & emailed me their summary.

A slide titled "Interview with Heather Moncrief-Cox: Senior Research Associate Aboard NOAA Ship Oregon II." It features three images: two screenshots of students in a classroom looking at the camera, and one of Heather and Maronda sitting together in a room on the ship. Large speech bubbles containing quotes point to Heather.

McNair High Students Interview Jim Patterson, NOAA Fisheries Biologist aboard NOAA Ship Oregon II:

What was your most memorable moment at sea?

While I was doing my job a sperm whale came up from the water! It rolled over to the point where you could see its eye and we just stared at each other. It was so remarkable to me that I forgot to turn on my camera.

How does being at sea affect your family life?

I don’t have my own family so therefore that’s not a problem for me. I talk to and meet new amazing people all the time.

What advice can you give students?

Do whatever you are interested in and the work you do in the end will all be worth it! You’ll be happy that you did it.

What is rewarding about your job?

There’s so much that I’ve discovered over the years and new things that I’ve learned. The experience also is something that’s worth it, along with the view of the ocean and sights of the creatures.

How are environmental issues related to STEAM (Science, Technology, Engineering, Arts, and Math)?

STEAM applies to just about everything in life.

McNair High Students of Dekalb County, Georgia, interview Chuck Godwin, NOAA Lead Fisherman:

What certificates or degrees do you have?

I have a Wildlife Management Ecology degree and Multi-Management Certification.

How does your job affect your family?

When my kids were younger this would affect them because I would be gone 2 weeks to 2 months. They are grown now so not so much.

What was your most memorable moment at sea?

We caught a 27 foot basking shark.

What are some of the rewards with your job?

I like the long-lasting friendships and my shipmates are like a second family to me.

What are you looking forward to aboard NOAA Ship Oregon II?

I’m hoping to catch a record-winning great white shark.

Why is your research important?

I protect species and keep them going. I make sure they are okay.

Heather Moncrief-Cox: Senior Research Associate

McNair High Students of Dekalb County, Georgia, Interview Heather Moncrief-Cox, NOAA Senior Research Associate:

When did you realize you wanted to pursue a career in science or ocean care?

I’ve always wanted to do this ever since 3rd grade when I dressed up as a Marine Biologist. At 13, I started shark diving.

Why is your research important?

It’s important to do research because it allows you to learn information you might not have known before. You can also gather evidence or proof to contribute to the information you learned.

Heather makes sure data is recorded and tissue samples are stored properly for later research.

On Friday, September 2nd, 2022, the students in my Analytic Geometry class interviewed Fisherman Josh Cooper. He was very helpful with different positions on the deck. He explained his life at sea & talked about some of the fish he recently caught. Later during the week, he prepared ceviche for everyone with the fresh catch of the day.

What are your normal duties?

I maintain the deck, catch fish, and work where I’m needed.

How does your job affect your social life?

You have to know what you are getting into. I’ve been on the vessel for about 2 months. It’s a challenge and it’s all about knowing how to manage your time. NOAA is really good about giving time off.

On Thursday, September 8th, 2022, I interviewed my supervisor Trey Driggers & Fisherman Chris Love. I was able to use a Voice Recorder APP & my phone to capture the moments. Trey was very detailed with explaining the purpose of collecting the data & helped me increase my marine life vocabulary. Chris shared lots of sunrise pictures & we often compared photos between shifts.

McNair High Math Teacher of Dekalb County, Georgia, Interviews Trey Driggers: Supervisor and Chief Scientist:

“We collect otoliths (inner ear bones) from bony fish species that help the fish navigate near reefs. Then we send the samples to the Panama City Lab to determine the age of the fish. They compare the age & length to see how fast they grow.”

How do you keep the bait organized?

You have to go in order so the lines don’t get crossed. We put a total of 50 hooks with bait in each barrel. The last one in is the first one out. Make sure you put the hooks in the Mackerel bait twice to be more secure. Sometimes you’ll get pieces of the bait back or none at all. If we’re lucky, then we’ll catch a few fish. The numbers on the hooks help us stay organized too.

McNair High Math Teacher of Dekalb County, Georgia, Interviews Chris Love: NOAA Able-Bodied Seaman/Fisherman:

What challenges do you face?

Being away from home. Sometimes you miss out on things. If you play around and don’t pay attention, then you can get seriously hurt.

Do you have any memorable moments?

You get to go to different places and experience things away from home. You meet new people on the ships and ports you visit.

On Friday, September 9th, 2022, my students interviewed Lieutenant Commander, Aaron Colohan. He has a lot of responsibilities & made sure we were safe on the ship. He has a large budget of 1.2 million dollars with many factors to consider.

What are some rewards you get from your job?

I believe in what I’m doing. My reward is doing something for my country, the world, and the planet. This is an opportunity to work outside of the military for public good.

I have to work with 23-30 people a day and make sure they are happy in their environment along with me. I make sure they are well fed and safe with a $1.2 million budget.

On Monday, September 12th, 2022, I interviewed James McDade, Junior Engineer. I had to use ear plugs because the noise level is very loud on the bottom of the ship where the engine & equipment is located. It was very hot & the space was tight.

McNair High Math Teacher of Dekalb County, Georgia, Interviews James McDade: NOAA Junior Engineer:

What made you choose this career?

I got lucky because I was supposed to only work for 60 days, but I was offered a permanent position over 20 years ago. I had no idea. I’ve been able to travel and see beautiful places all around the Hawaiian Islands.

What challenges do you face?

What I do is maintenance. If anything breaks down, I repair it. I check the refrigeration, water leaks, engines, change filters, and pipe system. Before, it was easy to save money while at sea, but now due to online services I spend more.

Can you describe a memorable moment?

When I worked in Hawaii it was fun going to all the different islands and meeting new people. I also visited Taipan China & Guam. I enjoyed having fun in those places. The atmosphere is nice with everyone getting along.

Do you need a degree or certification for your career?

Yes, I went to training at SIU Piney Point Maryland. That’s where I picked up my last endorsement. I need one more license to be an official engineer. I have to study on my own & take the test.

What advice would you give students?

Check out the different careers. Keep a clean record because you are dealing with the government. You want to make sure you can travel, get a passport so you can see the world. I would also say learn how to work with people. You don’t have to like everybody but be respectful & know how to work together.

Personal Log

I am glad we are on our way to the Gulf of Mexico! The shoreline is gorgeous & the skyline is ever changing into patterns of colorful art. Soon I will no longer see land & view the ever-changing skyline. I’m excited that I get to share this experience with my students & colleagues while sailing. My shipmates work well together & are willing to pitch in wherever they are needed.

Science and Technology Log

We are continuing our path due east. We (they) have surveyed 14 different banks and dropped 102 cameras.

*NERD ALERT*

Along the way we have been collecting water samples that contain environmental DNA (eDNA), and mapping at night. Caroline Hornfeck, graduate student at the University of West Florida, is collecting water samples once daily and at additional fixed sites. She is working under Dr. Alexis Janosik, participating in a multiyear study of reef fish in the Gulf of Mexico with the Florida Fish and Wildlife Conservation Commission (FWC) and NOAA. The project’s goal is to characterize reef fish diversity in the northwest Gulf of Mexico using molecular tools and techniques.

Environmental DNA is a molecular tool used in aquatic ecosystems. eDNA contains DNA from all organisms in the water column. This DNA can be in the form of gametes (reproductive cells), fish scales, waste, etc. This approach is noninvasive and cost-effective, and does not require contact with the organism. Caroline collects test tubes of water, adds some magical juice that causes a chemical reaction, and the DNA begins to solidify in the test tube. You with me? THIS is real science.

Later in the lab, the eDNA is extracted and the samples are run through polymerase chain reaction (PCR). PCR amplifies (multiplies) genes and the sample is sent to a lab for additional science. Fancy technology makes millions of copies of the DNA. You piece it all together and use the data to assess reef fish diversity. Essentially, eDNA is like taking attendance in the reef community. Roll call.

I will leave it at that, though it’s much more complex. I am starting to remember why I avoided molecular biology. Caroline, I’m impressed.

Meet the Science Crew

Paul Felts
Field Party Chief, Fisheries Biologist

Field Party Chief Paul Felts holds up two fish sampled during the reef fish survey

What do you enjoy most about your job? “It’s the field work that I enjoy most. I love being out on the water (in moderation), participating in the various surveys. I have been a part of so many fun surveys – reef fish, snapper longlines, trawls, plankton, and mammals. I appreciate getting a break from the desk, reviewing footage, and annotating the research. I also enjoy working with the crew and building team camaraderie.”

What is the coolest animal you have seen or worked with? “It’s tough to decide. I have seen all sorts of cool stuff. One mammal survey we were out on the smaller boat and a sperm whale breached about 100-200 yards from the boat. Later those whales were lying on their sides at the surface with full bellies, seemingly just resting after a meal. The giant stingray and thresher shark are up there on my favorites as well.”

Paul is the Field Party Chief. He’s been with NOAA for 21 years. As a Fisheries Biologist at the Southeast Fisheries Science Center, Paul studies fish populations and their impacts. He knows every fish in the sea (or at least close). Out here, Paul coordinates scientific operations. He has to be on every minute of every day, and deal with the crews’ shenanigans, yet still shows up each morning with a smile on his face, ready to take on the day.

Amanda Ravas
Fisheries Biologist

What do you enjoy most about your job? “My favorite part about my job is being out in the field… as long as I’m not seasick. Because I’m still so new, I love learning all the ins and outs of the projects, seeing the species I’ve been watching on our videos in person, and hearing stories from other scientists about all the cool projects they’ve been a part of.”

What is the coolest animal you have seen or worked with? “The coolest animal I’ve seen while out in the field is a manta ray which followed our boat for a few minutes as we were making our transit back ashore. And I always get super excited seeing any shark species while out at sea.”

Amanda is a Fisheries Biologist at the Panama City Laboratory. She’s been with NOAA for two years. She studies fish populations and their impacts. She may be tiny, but she’s mighty. Don’t underestimate her. She knows her stuff, and knows it well, and can keep up with the best of them.

Rafael Ortiz
Program Support Specialist

What do you enjoy most about your job? “I enjoy being part of the NOAA Fisheries Mission at the MSLABS level. Being an administrator I find myself lucky to participate on various surveys with the scientist. I get to build a great working relationship and many friendships with them. I learn so much from them. Everything from science related topics to personnel life topics. I also feel that they have a higher respect for me than just some admin person.”

What is the coolest animal you have seen or worked with? “Oh so many to list. I’ve seen so much diversity on these surveys that it’s hard to list. I’m always amazed at what comes out of the ocean and the thought of things I’ve not seen or will never see. I’m fascinated by the smallest to the biggest ocean animals.”

Rafael is a Program Support Specialist. He has been with NOAA for seven years. He provides oversight, technical expertise, and support to personnel and field biologists. But don’t let him fool you; he’s a biologist at heart. These scientists are lucky to have him out here at sea. He works hard, and best of all, keeps everyone in good spirits.

Kenneth Wilkinson
Electronics Technician

What do you enjoy most about your job? “All of it. I have done just about every survey – plankton, sharks, small pelagic, reef fish, Caribbean reef fish, and more. I have worked closely with NOAA enforcement, installing vessel monitoring systems and reporting illegal fishing. Surveillance in the Keys was a lot of fun. I enjoyed being down there. Most recently, I operate NOAA drones.”

What is the coolest animal you have seen or worked with? “The first to come to mind is the 12 ft. tiger shark during a longline survey. I also enjoyed building satellite tags and tagging sea turtles.”

Kenny is an Electronics Technician at the Southeast Fisheries Science Center. He has been with NOAA for 32 YEARS. He handles all the equipment from scientific to shipboard navigation and communication. What would we do without Kenny? This survey, as well as most, relies entirely on the technology. Kenny keeps us in check. I mean he’s the only one that knows what a transmissometer is.

Caroline Hornfeck
Graduate Student, University of West Florida

Graduate student Caroline Hornfreck, wearing a hard hat, life vest, and gloves, sits at a desk in the wet lab aligning sample tubes in a styrofoam holder

What do you enjoy most about your job? “What I enjoy most about being a student in this field, is always adapting and learning new skills that can help me grow as a scientist. Whether that’s in the classroom, research lab at the University of West Florida, or aboard NOAA research vessels.”

What is the coolest animal you have seen or worked with? “One of the coolest animals I have seen is a spotted eagle ray. I hope further down in my research career I can work with elasmobranchs (sharks, skates, and rays) and implement better conservation management for keystone species.”

Caroline earned her B.S. in Marine Biology at the University of West Florida. She is pursuing her Master’s at UWF. She is doing real science out here. Are you even a scientist if you don’t collect DNA? This girl is going places for real.

Personal Log

When 2 or 3 o’clock rolls around, I have to shake things up a bit. I’ve started making rounds just to say hello and see what people are up to. I remind folks that what they do is really cool. I make my way to the bridge usually once or twice to bother them a bit. This is where the ship is commanded. It looks like some sort of spaceship up here. I roam around and try to make sense of the many gadgets and screens. Take a peek out the windows. The sun reflects intensely on the water. It’s hella bright out here.

Operations Officer, LT Christopher Duffy, asks “Do you want to drive?” I look over my left shoulder, I look over my right. Oh, he’s talking to me. “Uh, yeah I do.” I have absolutely no clue what I just signed up for. He seems to think I can handle it. I get the run down. The helm is the steering wheel – check. The main engine controls the propulsion – check. Then there are the bow thrusters. From what I understand, they are basically propellers on the side of the boat. I’m not really sure. I just know they improve maneuverability.

Navigation is an art and science. They transit to specific destinations and position and maneuver the ship and make it look easy. Navigators measure the distance on the globe in degrees. If you have forgotten, like I seemed to have, like a circle, the Earth has 360°. Compasses have four cardinal points (directions), right? – North (N), East (E), South (S), and West (W). Well, turns out when you’re real official, you use degrees instead of directions. As if directions weren’t confusing enough. LT Duffy, “When I say 10° right, you do just that and confirm when you’re there.” I can handle that. “Ten right.” I work with LT Duffy to retrieve our next buoy. Huddleston keeps a careful eye. This is fuuunnnnn. “You ready for a hard right?” “Like all the way?” Seems questionable. Oh he’s serious. “Hard right rudder.” SKKKIIIIRRRRRTTTTTTT. Man this thing can move. We Tokyo drift right into position. Nailed it. LT Duffy takes control to finish positioning (I made it easy for him). I’m grinning ear to ear.

“Are you comfortable giving commands?” “Yep.” The overconfidence kicks in. First things first, CONN candy. What’s that you ask? The officers up here have a secret drawer of tasty treats that they’ve been hiding from us this whole time. Gotta have some before taking command. Wait, what am I doing? LT Duffy explains, “You’ll be giving commands to LTJG, Ariane Huddleston, while she steers.” Uhhhhhhh. I see the fear in her eyes. “Just repeat after me.” Huddleston takes the wheel and I “give commands.” It clicks. This is my time to shine. I “very well’d” the heck out of those commands. So much fun, thank you crew!

Did You Know?

You know all those horrid COVID tests you had to take? You were doin’ science right there. The polymerase chain reaction (PCR) tests genetic material (fluid from the nasal swab). The test detects the virus that causes COVID-19. Scientists use the PCR technology to amplify small amounts of RNA from specimens into DNA, which is replicated until SARS-CoV-2 is detectable if present. It’s cool stuff guys.

Interview with the Chief Scientist

When Sarah Stienessen was a little girl, she got a book about dolphins, and fell in love. She read the book over and over, dreaming about meeting a real-live dolphin one day. The problem was she grew up in Wisconsin, not a place with a lot of dolphins. However, as Sarah says “If you have an interest, don’t let location deter you from your dreams.”

When she grew up, Sarah studied zoology at the University of Wisconsin, Madison, but her burning fascination with the ocean led her to graduate school at Texas A&M where she finally got to study DOLPHINS (more specifically, the vocal behavior of dolphins). Her research there included using a hydrophone to listen to dolphins. She later moved to Seattle and began working for NOAA conducting acoustic surveys on walleye pollock in Alaska. On this leg of the Oscar Dyson, Sarah acted as the Field Party Chief (or Chief Scientist). Sarah pointed out that while her use of acoustics with dolphins was passive (placing a hydrophone in the water and listening to the dolphins) she is now using acoustics actively by sending an audible PING into the water and reading the echos that the fish send back.

Sarah was part of the amazing NOAA science team onboard the NOAA Ship Oscar Dyson, which included, Denise McKelvey, Kresimir Williams, and Taina Honkalehto.

Scientists — Back row: Sarah and Kresimir Front row: Denise and Taina

Denise was on the day shift, so I mostly saw her during shift changes and on those rare mornings when I was still awake at 7 a.m. and came down for breakfast (okay, bacon). However, early in the trip, she took the time to explain the fish lab procedure to me, even drawing pictures and a flow chart. (Thanks!)

While the duties of the science team often overlap, Kresimir is definitely the “techie” who enjoys inventing and creating new underwater cameras and other devices. Do you remember the TV show MacGyver? MacGyver was a secret agent who was beyond resourceful and had an encyclopedic knowledge of science. Every episode, he would solve the problem at hand in a matter of minutes using a combination of ordinary objects such as duct tape, household cleanser, a Q-tip, and some matches. Kresimir reminded me of MacGyver. If something broke, he would enter the room, grab tools and items that just might work in place of the broken piece, and sure enough, within minutes, the device would be up and running again!

Taina was always in the chem lab during drop camera time, her eyes riveted on the screen. I was excited whenever the camera spotted something, but I loved that Taina seemed equally excited to see what marine species the camera would uncover each night. One of the most exciting, and clearly the biggest, was the Giant Pacific Octopus!

Science and Technology Log

The Giant Pacific Octopus (or Octopus dofleini) is often rumored to weigh more than 600 pounds, but most adult octopuses are much smaller. An adult female might weigh up to 55 pounds while an adult male can weight up to 88 pounds. According to NOAA, the plural of octopus is octopuses, NOT octopi as some people say. Because it doesn’t have bones, a giant octopus can squeeze through a hole the size of a quarter! The body of an octopus is shaped like a bag and it has 8 long arms (or tentacles) covered in suction cups.

A mature octopus can have as many as 280 suction cups on each arm. That’s 2,240 suction cups! The Giant Pacific Octopus loves to eat crabs, but it will also eat snails, oysters, abalone, clams, mussels, and small fish. The octopus’ mouth or jaw is shaped like a parrot’s beak. It is the only hard part of an octopus, and it’s more-or-less indigestible. That means that if a sperm whale eats an octopus, and the contents of the whale’s stomach are later studied, you will see the octopus beak even if you find no other sign that he ate an octopus.

In order to avoid whales and other predators, an octopus will camouflage, or change its color and skin texture to match its surroundings! When he feels threatened, he releases a cloud of purple-black ink to confuse his enemy.
