Science and Technology Log: 

We have finished five transects with two left to go. Today (Saturday 7/19) we had the deepest drop to 2000 meters and collected eDNA samples for future processing by the Monterey Bay Aquarium Research Institute (MBARI). The work with eDNA (DNA shed from animals that have been in the area in the last 24-48 hours) compliments the first hand observations that the scientists on the deck are making. These samples are sent to MBARI and will be processed in 1-2 years. The time does seem long, yet the greatest challenge is getting the samples in the first place. So we are doing the essential work towards developing a deeper understanding of species distribution and how seamounts may be influencing the oceanโ€™s biodiversity.

Once the CTD measurements and water sample collection is done at a station location, the ship moves again to the next CTD location on the transect. While the ship is moving along the transect, the seabird and mammal scientists are at work on the flying bridge (top deck of the ship) counting species seen within the observation zone (as detailed in previous post). So far, in five days of research, we have the following results.

  1. Tuesday: 331 observations- 284 seabirds, 47 mammals
  2. Wednesday: 303 observations- 274 seabirds (107 Red-necked Phalaropes), 29 mammals (19 fur seals, 6 whales)
  3. Thursday: 173 observations- 120 seabirds (mostly Red-necked Phalaropes, storm petrels and Ashy Storm Petrels), 53 mammals (mostly fur seals, whales and dolphins)
  4. Friday: 136 observations- 92 seabirds (mostly Leachโ€™s Storm Petrels), 44 mammals
  5. Saturday: 74 observations- 40 seabirds, 34 mammals (mostly whales)

Our effort is adding up and we now have 994 observations! The team is happy as we have been having good weather and calm seas to allow for good observational data collection.

Alongside the research that we are working on, we are also having some fun with โ€˜ocean shrinky dinksโ€™. As you descend in the ocean, the pressure changes, increasing one atmosphere (14.7 pounds/ sq. inch) for every 10 meters below sea level. Animals adapt in many ways to this changing pressure; whales collapse their lungs when they dive deep and rely on the oxygen in their blood and muscles during this time. We can see the results of this change if we send a material like styrofoam down; the pressure squeezes the air out and the item shrinks. The deeper the object goes, the more the air is squeezed out and the smaller it gets.

We decorated styrofoam that are in the shape of cones, bears and birds โ€“ thanks to marine ecologist Erica Burton who brought all the materials and decorating pens. We then attached these items in laundry bags to the CTD rosette on deeper drops of 1620m, 1710m and 2000m (the blue dots on the transect map shared in the last post). Once we pulled up the CTD rosetteโ€“voila! our โ€˜shrinky dinksโ€™ were ready, at a fraction of the original size! I am very excited to share these tangible projects with my students as they learn about the ocean.

Meet the Science Team!

I would like to introduce the team behind all this amazing science. Our chief scientist is Chad King, a research ecologist from Monterey Bay National Marine Sanctuary (MBNMS), also known for being the chief scientist on the 2018-2020 EV Nautilus expeditions with Ocean Exploration Trust that discovered the octopus garden along the flanks of Davidson Seamount at 3200 meters deep. A fun fact is that back in 2019, my class scored a virtual interaction with the Nautilus as it explored the deep ocean, with Chad as our ship-to-shore connection. Chad answered many of my students’ questions about studying the deep sea while actually on board the Nautilus. I never imagined that one day I would be able to join him on a research mission!

Assisting Chad with the CTD and eDNA work in the wet lab is Erica Burton, also a research ecologist from MBNMS. Erica specializes in ichthyology (study of fish), but has co-authored many research papers and the Davidson Seamount Taxonomic Guide, so she is known as a species expert. I am grateful to both of them for taking the time to explain the details of their work with me and for teaching me how to do eDNA sampling.

Interview with Chad King:

Chad is a research ecologist with MBNMS who has a background in kelp forest ecology, GIS and he is an expedition diver and diver trainer with NOAA. He has been working with NOAA since 2008 and has been involved in various projects with the sanctuary including microplastic monitoring. He lives in Gilroy with his wife and two children Maya and Noah. Maya is studying at UC Berkeley and Noah is in high school.

Why is your work important?

Regular research, with our partners, is important for the sanctuary because we study priority or new issues such as kelp loss and microplastics, but we are also working on the ongoing characterization and exploration of the sanctuary. Exploration is so valuable because you donโ€™t know what you will find.

What do you enjoy about your work? What is a challenge?

I enjoy the variety of work- I get to be a โ€œjack of all tradesโ€- and do different work week to week. It is fresh and engaging and I am exposed to more subjects related to the sanctuary. A challenge is having enough time to analyze the data since I am moving from project to project.

When did you know you wanted an ocean focused career?

As a child I feared the ocean, and over the years I learned that the best way to overcome fear was with knowledge. I watched a lot of ocean documentaries by Jacques Cousteau and visited the Monterey Bay Aquarium. By middle school, I knew I wanted to be a marine biologist. After high school, I went to UC Santa Cruz and majored in marine biology. After trying out working in real estate for 4 years, I returned to marine biology for a masterโ€™s degree from Moss Landing Marine Lab.

What book/activity do you recommend to a young person interested in an ocean focused career?

Bully for Brontosaurus: Reflections in Natural History is an engaging book that focuses on science and critical thinking skills. Reading it turned me on to science. I also recommend trying snorkeling as early as you can. Also, if it is possible, become a certified SCUBA diver. You can do so as early as age 10.

The Bird and Mammal Team

While Erica and Chad work in the wet lab, on the flying bridge are the bird and mammal specialists from Point Blue Conservation Science. Point Blue is a group of  โ€œ160 scientists who work to reduce the impacts of climate change, habitat loss, and other environmental threats while developing nature-based solutions to benefit both wildlife and people.โ€

On our mission we have biologists Jim Tietz, Rudy Wallen, Julie Howar and Mike Johns from Point Blue. We also have Holly Lohuis, a marine life naturalist from Island Packers; Melissa Ashley, a CA Sea Grant Fellow; and NOAA Hollings Scholar Kylie Marozsan.

Mike Johns, Point Blue Marine Scientist

Interview with Marine Ecologist Mike Johns

Mike Johns is a senior marine ecologist on our team. He works for Point Blue Conservation Science which is based in Petaluma. His focus is seabird studies and the Farallon Islands. He lives in Tacoma, Washington with his husband and his dog Noosa.

Why is your work important?

My work brings an understanding of how seabirds and the ecosystem depend on one another and respond to changes in our planet. Iโ€™m documenting how our actions impact the organisms we share our planet with.

What do you enjoy about your work?

I enjoy collecting data in the field through hands-on studies of birds, and once back at the office, revealing hidden patterns with long term data sets and creating engaging graphics – like animations of plots – that the general public can learn from.

What is a challenge?

Navigating the politics of work and staying funded are challenges. Working remotely is hard because you have no friends to bounce ideas off of.

When did you know you wanted an ocean focused career?

Iโ€™ve always loved camping in the Sierra Nevada as a kid, and surfing – once I discovered the ocean. Right after high school, at the age of 18, I worked as a deck hand on a whale watching boat in Monterey. The whales were cool, but I was captivated by the sea birds and how they can be the tiny size of a sparrow and spend their whole life at sea.

What was your path to becoming a marine ecologist ?

I attended CSU Monterey Bay and majored in environmental science. After graduating, in the summer of 2012- from March to August- I did the Farallon Seabird Internship. I lived in an 1850โ€™s lighthouse keeperโ€™s house with 4-8 others and was immersed in wildlife and the ocean. Whenever you went outside the Western Gulls were attacking us! On the Farallones, I learned about observation, banding and other elements of field research. This experience gave me the background to get other projects. I have worked on various sea bird projects in the Bering Sea (Alaska), Hawaii and Tasmania.

What books and activities do you recommend to someone who is interested in an ocean focused career?

Carl Safina has written many books on the ocean. I recommend Song for the Blue Ocean and Eye of the Albatross. For activities, I recommend tidepooling, bird and whale watching and โ€ฆ. looking at a droplet of water under a microscope.

Holly Lohuis, Island Packers Naturalist

Interview with Naturalist Holly Lohuis

Holly is a naturalist with Island Packers, the boat concession to Channel Islands National Park and marine educator with the Santa Barbara Maritime Museum. She also is the co-director of the newly designated Santa Barbara Channel Whale Heritage Area and has been an expedition diver and marine biologist with Jean-Michel Cousteau (son of Jacques Cousteau) and his marine conservation organization, Ocean Futures Society since 2002. She lives in Carpinteria with her partner Chuck and son, Gavin.

Why is your work important?

The ocean covers over 70% of our planet and contains over 90% of the living space. Yet, there are many unknowns about the ocean, especially in the deep sea and the rich diversity of marine life around seamounts. Thatโ€™s why long-term monitoring by the Monterey Bay National Marine Sanctuary (MBNMS) is vital for informing decisions about preserving these unique ecosystems.

What do you enjoy about your work here at Davidson Seamount?

I love being part of a team where the crew and scientists all share a deep passion for ocean conservation. Every day, Iโ€™m learning something newโ€”especially about seabird speciesโ€”thanks to the expertise of our seabird biologists. 

What is a challenge?

It is a challenge to be away from home but my work for decades has taken me away from home, traveling around the world with Jean-Michel Cousteau and his expedition team. But I still miss Chuck, Gavin, my friends, family and my cat Avalon. 

When did you know you wanted an ocean focused career?

In 5th grade, my teacher Ms. Brown asked us to do a report on who we wanted to be when we grew up. I chose Sylvia Earle because I was fascinated by her deep-sea dives and ocean exploration. I also loved watching the Undersea World of Jacques Cousteau and like many people, I dreamed of being a silver suited diver on Cousteauโ€™s team. Growing up landlocked in Sacramento, I knew Iโ€™d eventually want to live by the ocean.

What was your path to becoming a naturalist?

I went to UC Santa Barbara and majored in aquatic biology. In my last year of college, I interned at the Marine Mammal Rescue Center in Santa Barbara. After graduating, I worked at a local dive center in Santa Barbara and then with Island Packers. I also connected with Jean-Michel Cousteau and was hired as a diver and marine biologist at his small eco-resort in Fiji. My experiences both aboard Island Packersโ€™ boats and while working in Fiji deepened my passion for educating others about the incredible diversity and delicate nature of both kelp forests and coral reefs, and how each of us can make a meaningful difference in protecting our ocean.

What books and activities and advice do you have to someone who is interested in an ocean focused career? 

I recommend any books by Dr. Sylvia Earle like The World is Blue and Sea Change. I also love books by Carl Safina, Susan Casey and Cullum Roberts.

Take advantage of internship opportunities. Volunteer for local marine or coastal organizations and meet like-minded people who can be mentors and help with job opportunities.

Getting scuba certified can open up many opportunities in marine science and conservation work.

Go whale watching! Follow your curiosity. Learn the science. Spend time in, on, and near the ocean. And most of allโ€”share what you love with others. Ocean careers need storytellers, scientists, educators, and advocates working together.  

Personal Log:

I am getting into my routine of waking up and joining the observation crew on the flying bridge. It is such a beautiful gift to be out on the Pacific learning to do bird and mammal observations. I am gaining observation skills and have been seeing so many more animals. I know now how to spot groups of whales far out on the horizon. I have observed minke and blue whales and marveled as Laysan Albatross and Black-footed Albatrosses gently glide over the surface of the water. I am so happy to learn about these types of albatrosses in Monterey Bay National Marine Sanctuary. My students and I have been studying albatrosses in the context of Antarctic animals and now I have the knowledge to teach about these local species.

The animal observations on the flying bridge last approximately 45 minutes to one hour and then there is a break during CTD rosette deployment stops. Some scientists go for coffee and snacks; others -like Holly- go to the gym and run a mile on the treadmill. Holly has been an inspiration and I am also going down to the gym to work out once a day (Holly goes 3 times a day to run over 3 miles!). I am quite proud of myself for being able to do cycling and the elliptical machine with all the rocking of the boat. The waves are getting a bit stronger these days and I am adapting.

I have also been getting to know many of the people on board that are supporting the work of the scientists- both NOAA Corps and the crew. I have been interviewing some of them to prepare for future posts. Our meals continue to be amazing; tonight for Sunday dinner we had steak and lobster as an option. On every cruise, there is a special meal night and tonight was that night. Thereโ€™s always a vegetarian option as well as a large salad bar at every meal. Tonightโ€™s special desert was the ice cream sundae which is appropriate since it was World Ice Cream Day!

We are also building community aboard the ship as time passes. It is a bit like being in a dorm in college; however, we are even more tightly together since the ship is our only place to go. Yet, it is wonderful to share a space so closely with people that have a passion for science, the ocean and its conservation. With shipboard life, they also have the time and interest to share their knowledge. I am learning so much from every person I meet. I am also amazed that so many people – especially on the crew- have worked in Antarctica.

We are also having fun. On Saturday, we had a barbeque with a cooking challenge. The crew set up a cornhole game on the lower deck. In the evenings, after dinner and after our 8 o’clock science meeting, we play card games. Amity, my roommate, leads these with a treasure chest of games she has brought on board. I have learned several new and wonderful card games – like Skyjo and Exploding Kittens- to share with my class.

Did you know?

Black-footed Albatross nest in the Hawaiian Islands and 98% of the species lives there. They mate for life, lay one egg per clutch and are very long lived; the oldest recorded was a male at nearly 61 years old. They have a keen sense of smell and can detect their favorite food as they glide over the vast ocean. Their wingspan averages 6โ€™9โ€. Like other seabirds, the albatross can drink saltwater because it has special glands above the eyes that excrete the salt out of their tubenose bill.  Black-footed Albatross are on the threatened species list and are threatened by plastic pollution, oil spills and long line fishing.

Meet the Scientists!

Hi, Iโ€™m David Richardson! I live in South Kingstown, Rhode Island, but grew up in Sierra Madre, California. I studied Natural Resources at Cornell University, then went to grad school at the University of Miami. Iโ€™m the chief scientist on this cruise, which means I help plan how we collect data to meet our science goals. My research focuses on larval fish, fish migrations, and how ocean conditions affect fisheries. My favorite marine animal’s the sail fish. Theyโ€™re beautiful at every stage of life! I love science because it helps us make the world better. In fisheries science, our work helps keep fish populations healthy so people can continue to enjoy fishing and have access to food.

Fun fact: My first research was on baby eels near Barbados. I discovered and illustrated six types of eel larvae that were new to science! That experience showed me how much of the ocean is still a mystery. My advice: Pay attention in math and writing but also get outside! Observing nature is one of the best ways to become a great scientist.

My name’s Allison Black! Iโ€™m from eastern Connecticut and often at sea. I studied Zoo and Wildlife Biology at Malone University and worked briefly as a zookeeper before focusing on ornithology. My favorite (yet unseen) marine animal is the Wandering Albatross. They can travel over 75,000 miles a year! On this project, Iโ€™m surveying seabirds and marine mammals. I love the oceanโ€™s mystery and the chance to keep learning through different cruises. Fun fact: by yearโ€™s end, Iโ€™ll have 500 sea days! My advice: stay flexible, stay curious, and seize opportunities you didnโ€™t know existed.


I’m Chrissy Hernรกndez! I grew up in New Jersey and now live in Oxford, England. I earned my bachelorโ€™s from Columbia University and my PhD from the MIT-WHOI Joint Program in Oceanography. Iโ€™ve worked as a researcher at Cornell and Oxford. Iโ€™m a population ecologist who studies biological oceanography and theoretical ecology. My favorite marine animal is the bluefin tuna! Aboard the ship, I help deploy plankton nets, identify tuna larvae, and guide sampling efforts. I love the oceanโ€™s vastness and mystery, and how tiny organisms like phytoplankton produce half the worldโ€™s oxygen. Fun fact: I once shaved my head and tossed the hair overboard during an equator-crossing tradition!

Hi, I’m Autumn Moya! Iโ€™m from Colorado and now live in Silver Spring, Maryland. I studied Biology at Western Colorado University with a focus on environmental biology, and Iโ€™m finishing my Masterโ€™s in Coastal Science at the University of Southern Mississippi. My research models how offshore development might affect the Atlantic surf clam fishery. I’m currently a John A. Knauss Marine Policy Fellow with NOAAโ€™s Office of Marine and Aviation Operations. I support communications, policy, and events. Iโ€™m excited to join research cruises like this one. My favorite marine animal is the cuttlefish. Did you know they can change color as fast as a blink? Iโ€™ve always loved the ocean, even growing up in a landlocked state. Since finishing my bachelorโ€™s, Iโ€™ve lived in seven states! My advice to future scientists: stay curious and never hesitate to reach out. Science is for everyone!


Hi, I’m Amanda Jacobsen! I’m from Rhode Island. I studied Environmental Studies at Connecticut College and now I’m working on my masterโ€™s in Marine Biology at UMass Dartmouth. On this cruise, I help deploy nets and collect seawater to study the carbon in it. My favorite sea creature is the lumpfish. Look it up, itโ€™s cool! Iโ€™ve worked on over 80 boats, and I love biology because it lets me explore the hidden world of ocean life.

Sometimes only visible under a microscope.

My advice to you: Stay curious and try new things, you might discover something amazing or meet someone who inspires you!

Hi! My name is Kristen Walter and I live in Miami, Florida. I graduated from the College of William and Mary with a master’s in marine science. I now work for the University of Miami/CIMAS studying coral reef fishes and bluefin tuna! My favorite marine animal is probably the nudibranch! Iโ€™m here on this cruise to help locate larval bluefin tuna, set and recover nets, preserve and identify fish, and test out new methods of capture using light traps. A fun fact about me is that I got to participate in the Aquarius Reef Base Underwater Habitat in Key Largo when I was in grad school. If you’d like to get into marine science, look for summer internships. Many places offer programs for high school students. Get your feet wet. Anything is possible!

Safety first! I need to make sure I can stay afloat in case I ever have to evacuate into the water.

I tried on an immersion suit, or “Gumby suit,” to make sure I can float in water. It’s also designed to keep people warm in the water in case they have to abandon ship or go into the water.

So far, Iโ€™ve really enjoyed getting to know everyone on board.  Iโ€™m a lot more familiar with everything around the ship, including where all the rooms, crew members, and emergency equipment are.  Iโ€™m feeling excited about our mission once we set sail. 

Next time, Iโ€™ll be writing about a special tool we use called the CTD (Conductivity, Temperature, and Depth), which helps us learn more about the ocean!

Did you know?

NOAA ships have their own weather stations right on board.  That means they can measure wind, rain, temperature, and more.  Even while theyโ€™re sailing across the ocean!  What do you think scientists do with that information?

Tremont Consolidated Schoolโ€™s Drifter Buoys: Exploring Ocean Data in Real-Time!

I was so thrilled to learn that Tremont Consolidated School (TCS) had been given two drifter buoys, allowing our students to participate in a cutting-edge, real-world scientific endeavor. Through the National Oceanic and Atmospheric Administration (NOAA) Global Ocean Monitoring and Observing Program, our students will track these buoys as they gather crucial data from the ocean. This is a hands-on, dynamic opportunity that infuses real-time ocean observing system data into our science curriculum! NOAA Adopt a Drifter Program

Track Tremont Consolidated School’s drifting buoys here:
https://adp.noaa.gov/trackadrifter/tremont-consolidated-school

It displays the Drifter ID card, with info on where it was deployed, and shows a graph of temperature readings over time, and a small map of the trajectory.
View of the tracking webpage for Drifter #1

Whatโ€™s a Drifting Buoy? A drifting buoy, also called a drifter, is a floating data collection device that travels with ocean currents. These drifters are equipped to record various ocean parameters such as sea surface temperature, salinity, and wave height, all while transmitting this data hourly via satellite. The buoys provide valuable insights into oceanic conditions that impact weather forecasts, climate models, and even search and rescue operations.

Why Deploy One? The data collected by drifters offers key information that supports a wide range of scientific and practical applications. This data helps scientists understand how the ocean circulates, predict the movement of marine debris or oil spills, and make better weather predictions. By tracking our adopted drifters, TCS students will gain firsthand experience in how this scientific data is used to analyze the ocean and its far-reaching impacts.

Bringing Science to Life for TCS Students At TCS, students in our science classes will be tracking and recording the drifter buoysโ€™ locations and analyzing the data collected. They will plot coordinates on maps, explore ocean currents, and make connections between the data they collect and global environmental patterns. This interactive project brings abstract science concepts into a tangible experience, encouraging inquiry, problem-solving, and environmental stewardship.

Sailing into New Horizons: A Farewell as a NOAA Teacher at Sea

As I sit here reflecting on my time aboard the NOAA research vessel, itโ€™s hard to believe this chapter has come to an end. When I first applied to the NOAA Teacher at Sea program, I knew I would embark on a unique adventure, but I could never have imagined the profound impact this journey would have on me, both as an educator and as a person.

The early mornings watching the sunrise over the open ocean, the long hours of data collection, and the camaraderie of working alongside scientists and crew membersโ€”each moment has left an indelible mark. One of the highlights was observing the way oceanographic data is collected in real-time. Deploying CTDs, collecting plankton samples, and witnessing firsthand the vastness of our oceans reinforced the importance of understanding and protecting these ecosystems.

The lessons Iโ€™ve learned during this voyage are invaluable. I canโ€™t wait to bring the excitement of real-world science into my classroom, showing my students that science isnโ€™t just something they read aboutโ€”itโ€™s something they can experience. From tracking ocean currents to analyzing marine species, my students will have the opportunity to become oceanographers themselves, right in the classroom. I know the drifter buoy project, in particular, will captivate their imaginations.

This journey has rekindled my passion for inquiry-based learning and has reminded me that we, as educators, are lifelong learners. Iโ€™ve also come to understand the deep responsibility we have to educate the next generation about the importance of our oceans and the need for sustainable practices.

Of course, this experience would not have been possible without the incredible support of NOAA and the crew of the research vessel. Thank you to the scientists who patiently answered my endless questions and to the crew members who made me feel like part of the team. Your dedication to ocean science is inspiring.

As I sail back toward the shores of Maine, Iโ€™m filled with excitement for what lies ahead. I look forward to integrating what Iโ€™ve learned into my 7th and 8th-grade curriculum, empowering my students to become stewards of the environment. I also hope to encourage more teachers to take part in this incredible program.

Though this chapter is ending, I know itโ€™s just the beginning of a deeper connection with the ocean and its mysteries. As Jacques Cousteau once said, โ€œThe sea, once it casts its spell, holds one in its net of wonder forever.โ€ And I, for one, am happily caught in that net.

Science and Technology Log

Although our mission has been delayed by few days, there is still plenty of work to be done on board the NOAA Ship Henry B. Bigelow.  The deck crew and engineering department have been working hard to prepare for our departure tomorrow morning.

Today, I had the opportunity to tag along with Kate and Patrick, two of our engineers, to learn more about the pre-check work they were completing.  โ€œOn board ship, it is very important to keep the updated record of the quantity of liquids (in all forms) present in various tanks.โ€ (Marine in Sight

As part of the pre-check, Kate and Patrick recorded the readings from sensors, then manually checked the level of each fuel, bilge, and ballast water tank in a process known as โ€œsoundingโ€ the tanks. They applied Kolor Kut paste to sound tape in the measurement range reported by the sensors and lowered the tape to the bottom of the tank. Upon retrieval, the paste changes colorโ€”from light pink to red for fuel and from brown to red for waterโ€”indicating the levels.

Kate and Patrick compared these manual measurements with the sensor readings to ensure the sensors were accurately reporting the levels. Then they used a table to convert the measurements to the number of barrels. Soundings are crucial for identifying leakages or losses of fuel, maintaining the shipโ€™s stability, and ensuring that sufficient fuel and water are aboard for the voyage.

Personal Log

Meet My Roommates! There are so many amazing people aboard NOAA Ship Henry B. Bigelow for this mission.  I would like to introduce you to my roommates who were kind enough to let me interview them for my blog and share information about their science career paths.

What is your science degree, and how did you become interested in this field?

Emma Venarde recently graduated from Brown University with a double degree in Environmental Science, focused on Environmental Justice, and Music. Emma has always had a love for nature and became passionate about climate change as a child. She joined the Youth Climate Program and realized that she wanted to better understand human impact and discover ways to help humans and other animals and how they are affected by climate change.

Karen Beatty earned her bachelorโ€™s degree in Zoology from Michigan State University, worked as an environmental consultant for five years, and recently graduated with a masterโ€™s in Ecology from Penn State University. Initially, Karen was interested in becoming a veterinarian, but she learned that she preferred working with exotic animals and focusing on their behavioral health. This led her to an interest in becoming a zookeeper but eventually transitioned to wildlife biology. For her masterโ€™s, Karen aimed to deepen her quantitative knowledge and understanding of anthropogenic disturbances.

What motivated you to become a NOAA at-sea volunteer?

Last summer, Emma participated in the NOAA Chesapeake Bay Office (NCBO) and decided to apply for another internship opportunity through NOAA student opportunities. She sought more experience in fieldwork, particularly in collecting data and understanding how itโ€™s used for ocean energy. This unique experience aboard the NOAA Ship Henry B. Bigelow is something she wouldnโ€™t typically get, and sheโ€™s thrilled to be part of it.

Karen joined this mission as a fellow of the Knauss Fellowship. She believes this fellowship will not only enhance her fieldwork experience, especially in data collection and analysis but will also help her achieve a federal career aligned with conservation and policy development.

What advice would you give my students who are interested in a science career?

Emma: We need more people who are not just good at understanding science but are also able to communicate, collaborate, and think critically.

Karen: Be well-rounded! Interdisciplinary learning is crucial. Having a solid understanding of and skills in math, communication, policy, and regulations is essential to being a successful scientist.

This is our stateroom, also known as a cabin, that we will be sharing for the next two weeks. Itโ€™s a cozy space designed for practicality, consisting of four bunks, a small office area, lockers for our personal belongings, and a bathroom with a shower. While the quarters are tight, itโ€™s amazing how efficiently everything is arranged to make life at sea as comfortable as possible. Weโ€™ve settled in nicely, and this space will be our little home away from home as we embark on this exciting mission aboard the NOAA Ship Henry B. Bigelow.

Science and Technology Log with Career Highlights

Previously, I wrote about the day-time operations focused on surveying whales, dolphins, and birds. Through the 25-powered binoculars (big eyes), the large mammals in the distance look microscopic. Now, the sun has set and I take us underwater to learn about the tiny world of ichthyoplankton, magnified to reveal intricate details of their exquisite structures.   

Weather permitting, Nich Sucher (Survey Technician) works with the deck crew to deploy the CTD, which measures conductivity, temperature, and depth. This information is used to help scientists understand the physical, chemical, and biological changes of the ocean to help inform them of environmental changes. For example, Nich explained that data from CTDs are used to better understand why tuna were migrating away from Hawaii and towards California. The data can help answer whether the tuna are moving north for access to more oxygen in the water or for cooler temperatures. On our project, we deploy the CTD down to 1000m because that is where some of our deep diving cetacean species feed. Also, the temperature & pressure affects how sound travels through the water. This information can be used to calculate the speed of sound at different depths.

He looks down at the water as the CTD apparatus descends below the purple-blue surface of the water. In the distance, the sun has just set over the horizon, leaving orange, yellow, pink, purple skies dotted with a few scattered clouds.

Nich wanted to work for NOAA since he was in middle school! In high school he fell in love with fish. Initially he went to college in Iowa for soccer and then transferred to Carthage College, in Kenosha, Wisconsin to study environmental science, conservation and ecology. Nich did an independent study with his aquatic ecology professor on a coral reef project in Roatan, Hondurus. His senior thesis investigated the feasibility of releasing captive-bred axolotl (an adorable salamander thatโ€™s critically endangered and possibly extinct in nature) into the wild. After college, he had a job at an aquarium, and while he temped at US Fish and Wildlife studying chub and salmon, NOAA reached out about his job application. He started in January 2022 on the NOAA Ship Oscar Elton Sette!

Since the CTD is deployed to 1000m, a common extracurricular activity is to attach styrofoam objects to the instrument because they shrink as a result of the pressure! On a previous leg, Commanding Officer Fionna Matheson shrunk a styrofoam head, which can be seen in the picture of Nich above. A few of us shrunk decorated styrofoam cups.

The whole process of the CTD deployment and retrieval takes about an hour to an hour and a half. The Isaacs-Kidd Midwater Trawl (IKMT) net tow usually follows. Jessie Perelman and Dre Schmidt are the plankton researchers on board this leg of HICEAS. Most nights, we do 2-3 tows of the net. (They are affectionately called a โ€œtow-yoโ€ because the net gets towed in and out several times.) They use an inclinometer, a.k.a. angled angle, to measure the angle of the line (see picture below) and then confer with a chart to determine the length of the line needed to reach the desired depth. The chart is a good way to avoid on-the-spot trigonometric calculations. But itโ€™s a good exercise to ask yourself anyway: if you know the desired depth and the angle, how would you calculate the length of the line needed?

Dre stands on deck at night, facing away from the camera, over the rail. She wears a jacket, a life vest, and a hard hat. Beyond her, we see a davit arm leaning over the water and a cable (attached to the net) extending at an angle off to the right. With her right arm, Dre holds out an angled angle - it's a metal semicircle, like a protractor, with a swinging arm attached at the center point of the straight edge. Dre holds it by a handle, lining the straight edge parallel to the extended cable. The swinging arm hangs straight down to the ship. Dre can read the resulting angle in the markings on the semicircle.

After the tows, we bring the larvae into the wet lab and the fun begins. The goal is to sort out the fish larvae from the other larvae. Truthfully, I am not very good at sorting the fish and I just like to look at the organisms under the microscope. The most awe-inspiring creatures I saw under the scope were the shelled pteropods (sea butterflies) and a juvenile sea star that, according to Dre, may have recently morphed from the larval stage. With the naked eye, they look like marks made with a sharp pencil, but under the scope, the enormity of their existence is profoundly moving. While I could not capture these beauties in a photograph, I was able to capture other creatures.

Personal/Food Log with Career Highlights

As I fall into a daily routine, I periodically need small bits of irregularity for stimulation. This week, I was privileged enough to work with Chef Chris. Chef Chris is originally from north Philadelphia. In the absence of cable during childhood, he watched cooking shows like Yan Can Cook, Frugal Gourmet, and Julia Child on PBS. He started off cooking on NOAA Ship Rainier and now is the Chief Steward on NOAA Ship Oscar Elton Sette. We collaborated to make some pork dumplings and vegetable spring rolls for everyone. I cook at home often, but not for so many people, so Chris was essential in helping me scale up the dishes. We bonded over not measuring out ingredients so here is approximately the two recipes we used.

Chris, wearing a black chef's cap, stands at a large fryer in the galley. he's cooking three foods - eggs, pork, onions in large piles - and he reaches toward them with a spatula or perhaps a large knife.

Pork Dumpling Filling

  • 5 lbs of ground pork (when my mom makes these, we use a mix of lean ground pork and fatty ground pork)
  • Mirin (I use Shaioxing wine, but mirin is a good substitute!)
  • Soy sauce (we used Kikkoman; I like to use Pearl River Bridge Light Soy)
  • Green onions
  • Sugar

Egg Roll Filling

  • Green cabbage
  • Red Cabbage
  • Carrots
  • Mushrooms
  • Soy sauce
  • Hoisin

Several of us worked together to help fold the dumplings and egg rolls. I delighted in the number of different hands that contributed to feeding our community. Chef Chris expertly cooked everything and it was all gobbled up!

At night, I assist Jessie Perelman and Dre Schimdt with their plankton research. They were the first to come by to help fold dumplings. Jessie did her undergraduate work in biological science at University of Southern California (USC) with a plan to go to veterinary school. She worked in a marine science lab at USC, and then studied abroad in Australia to take more marine biology classes not available at USC. After she graduated, she got a job as research assistant at Wood’s Hole Oceanographic Institution, where she solidified her passion for research. She applied for graduate school and ended up at the University of Hawaii studying biological oceanography. Her dissertation focused on oceanographic influences on mesopelagic communities across eastern Pacific Ocean using insights from active acoustics, nets, and other sampling techniques. An interesting interdisciplinary part of her background includes learning about international policy on issues like deep sea mining. The international meetings with delegates were very informative for her. Sheโ€™s also worked on science communication writing, such as science blogging. In Fall 2022, Jessie started as a Marine Ecosystem Research Analyst at NOAA!

Dre Schmidt received her bachelors in biology at Florida State University. She took Calculus, Mathematical Modeling for Biology, Analysis and Statistical Design, and Physics to supplement her biology degree. She volunteered at a research lab on campus and after college, took a couple of years off to work in marine science education for 5th grade to college level students. She went for her masterโ€™s degree in Kiel, Germany to study physiological effects of low-level warming on coral and their larvae. She has been at NOAA for 2 years, first as a research associate and now as an essential fish habitat coordinator. What she loves about her job is the variety of responsibilities. She keeps busy by sorting plankton, doing genetics lab work, analyzing data in R, writing up results, and going to sea! Engaging in these different tasks help to activate different parts of the brain, which I can totally relate to! Her advice to students is to know your worth and ask for what you deserve. Her favorite fish larva is the very ugly Centrobranchus andreae simply because her name is found within the name of the organism. I canโ€™t blame her because my favorite flower is the Gaillardia for the same reason.

Matt Benes (Able-bodied Seaman and Deck Boss) took a break in his duties to fold some dumplings with us. Though Matt declined to be interviewed, I can tell you we share a deep appreciation for food as a mechanism for cultural, historical, and political understanding.

Jamie Delgado (Medical Officer) joined in on the egg roll wrapping. Jamie received her bachelorโ€™s in science and nursing at Rutgers University. She joined the Public Health Service (PHS), and worked at the Indian Health Service (IHS) in northern Arizona. Later, she worked at the National Institutes of Health (NIH) as a research nurse specialist.  Jamie earned her Doctor of Nursing at University of Maryland before coming to NOAA as ship medical officer. Jamie has so much good financial advice about scholarships and loan repayments programs. Check out these links to learn more:

She also shared that you can retire in a total of 20 years with uniformed services, you get a pension, healthcare benefits, a housing allowance, a food allowance, 30 days paid leave, and unlimited sick leave. Jamie has been in service for 10 years, and with NOAA for 1 year and 5 months.

Jamie also helped me out during our in-port during Leg 1. Snorkeling had dislodged some ear wax and clogged my ear for a couple of days making daily life really uncomfortable. Jason Dlugosโ€™s (3rd Assistant Engineer) โ€œear beerโ€ helped, but I was still off balance. Jamie had to endure the task of flushing my ear out over the course of two days. Eventually, I did have to go to urgent care to get the rest out. Now Iโ€™m 100%!

Last but never least, Octavio De Mena, a.k.a OC, (General Vessel Assistant in the Deck Department) came by to roll some egg rolls. He is originally from the Republic of Panama and loves classic rock music. While we have no intersection in our movie tastes, we share some similarities in the food we ate growing up due to the large Chinese population in Panama. According to the Harvard Review of Latin America, the first Chinese immigrants arrived in Panama in 1854 to build the Trans-Isthmian Railroad. The inhumane treatment and disregard for the workersโ€™ welfare is reminiscent of the situation a decade later with the Transcontinental Railway in the United States. This convergence of cultures led to haw flakes and dried plums in both our childhoods!

OC was an aircraft mechanic in the military reserves, and a security contractor in Latin America. He decided to come back to the U.S. to fulfill his dream job as a professional mariner. On his journey in pursuing his dream, he volunteered for the civil air patrol, and served as an auxiliary for search and rescue flying small Cessnas. He saw a NOAA ship at this job which prompted a search for a position within NOAA. He has been on the NOAA Ship Oscar Elton Sette since February 2023. On the ship, OC and I are regulars in the forward mess. Sometimes having opposite tastes works out in your f(l)avor, as I get to eat OCโ€™s tomatoes and watermelon jolly ranchers.
