Behind the Scenes: Collecting Plankton Samples on Our Mission
During this mission, we will be collecting plankton samples from over 120 stations in the Gulf of Maine and further south along the East Coast (see the figure below; Summer ECOMON Track Lines).

They are connected by straight black line segments showing the track of the survey. there are also some smaller black dots connected by bright green line segments. extra labels mark Georges Bank (east of Cape Cod), Maine, and Mount Desert Island. — Summer EcoMon Track Lines

But why focus on plankton? Plankton are the foundation of all oceanic food webs, crucial for the survival of larger fish, marine mammals, and birds. Any changes in plankton biomass can have ripple effects throughout the entire ocean ecosystem, impacting a wide range of species.

By studying plankton, we gain insights into the health of our oceans. The data collected from these samples will be invaluable in estimating the populations of certain fish species and identifying key spawning areas. Moreover, we can observe how fish populations are shifting or altering their habitats in response to environmental changes and other stressors. (NOAA Fisheries)

Collecting plankton samples during this mission is a collaborative effort, requiring the expertise of the NOAA Corp, engineers, deckhands, survey technicians, and scientists. Together, we work to deploy, retrieve, and prepare the plankton samples for research.

We use two types of Bongo nets for sampling: Baby Bongos, set in a 20 cm frame, and Big Bongos, set in a 60 cm frame. Each net has a specific purpose: one is labeled “I” for Ichthyoplankton and the other “Z” for Zooplankton. These nets, made from 333 µm mesh, are equipped with flow meters to measure the volume of water filtered during each tow.

Once the Bongo nets are lowered into the water, the Conductivity, Temperature, Depth (CTD) sensors immediately start gathering conductivity, temperature, and depth data. The nets are then lowered to about 10 meters above the sea floor and gradually pulled back to the surface. Care is taken to ensure the nets don’t touch the ocean floor, avoiding the need for a recast. Today, for instance, we collected samples from around 230 meters deep!

When the Bongo nets are retrieved, we promptly rinse down the nets to flush the plankton into the codends at the bottom of the nets. The nets are then untied, and the plankton are flushed into a sieve pan.

Next, we carefully rinse the plankton from the sieve into a glass jar, preserving the sample by adding 5% Formalin. The jar is then topped off with seawater, labeled with the station/event, and inverted several times to ensure the sample is well-mixed. On average, we collect about 32 jars of plankton per day.

Finally, the plankton are ready to be shipped off to a lab to be sorted and counted.

Steps for collecting plankton:

Life Aboard the NOAA Ship Henry B. Bigelow: A 24/7 Operation

The NOAA Ship Henry B. Bigelow never sleeps, which means someone is always awake and hard at work. This is no cruise ship—everyone aboard the NOAA Ship Henry B. Bigelow has a vital role to play. Most crew members work 12-hour shifts, ensuring the ship’s operations continue smoothly around the clock. In addition, all the department crew are responsible for safety drills, and are trained in firefighting and lifesaving equipment.

As part of the science crew, I work from 3 am to 3 pm, while my roommate takes over from 3 pm to 3 am. Our team of scientists are constantly collecting and uploading data to support our mission. Engineers, deckhands, and survey technicians work shifts from 12 am to 12 pm or 12 pm to 12 am.

Engineers keeping everything running efficiently and addressing any technical issues that may arise. They are responsible for the safe and proper operation of a ship’s machinery and equipment and other mechanical and electronic equipment onboard.

Survey technicians assist in the operations, monitoring, handling, and maintenance of various scientific gear. This includes annotating records and recording data; assist in the staging and set-up during preparations for, and at the completion of oceanographic or fishery research. They also perform oceanographic or fisheries observations, measurements, and calculations, assisting in the preparations, installation, deployment and recovery of oceanographic or fishery research equipment. (NOAA Survey Department)

The Deck Department operates the cranes and winches to deploy scientific equipment, and maintain the material condition of the ship. Electronics Technicians maintain the ship’s computer network and vital emergency communication and navigation equipment.

The NOAA Commissioned Officer Corps (NOAA Corps) operate and navigate the ship, and monitor oceanographic and atmospheric conditions, ensuring our safety and guiding us through each phase of the mission.

And let’s not forget some of my favorite crew members—the stewards, who keep us well-fed with amazing meals and plenty of delicious snacks.

Given the non-stop nature of our work, it’s important to remember that someone is always sleeping. This means being mindful of your noise level: avoid slamming doors, walk quietly down the halls, and always use your “inside voice” when moving about the ship. When living and working in such close quarters, professionalism, civility, and respect are essential to maintaining a happy and welcoming work environment.

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. “On board ship, it is very important to keep the updated record of the quantity of liquids (in all forms) present in various tanks.” (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 “sounding” 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 color—from light pink to red for fuel and from brown to red for water—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 ship’s stability, and ensuring that sufficient fuel and water are aboard for the voyage.

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.

Karen stands in a field holding a Canada goose under her right arm. She wears a long sleeve shirt, black gloves, and a baseball cap. — Karen Beatty (Animals were handled in accordance with state and federal permits.)

Emma stands one what is probably a boat in a marsh and holds up a snake for a photo. She wears orange fish gloves and a green high visibility vest. — Karen Beatty (Animals were handled in accordance with state and federal permits.)

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 bachelor’s degree in Zoology from Michigan State University, worked as an environmental consultant for five years, and recently graduated with a master’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 master’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 it’s used for ocean energy. This unique experience aboard the NOAA Ship Henry B. Bigelow is something she wouldn’t typically get, and she’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. It’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, it’s amazing how efficiently everything is arranged to make life at sea as comfortable as possible. We’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.

Introduction

Hello, my name is Tonya Prentice. I am so excited to begin my adventure aboard NOAA Ship Henry B. Bigelow for the NOAA Teacher at Sea 2024 Season. I teach middle school science for grades 5-8 on Mount Desert Island, Maine, at Tremont Consolidated School in Bass Harbor. This is my 17th year of teaching, and I am passionate about engaging my students with project-based learning, community service opportunities, and STEM activities.

In my role as an educator, I strive to create engaging and interdisciplinary learning experiences for my students with a focus on ocean literacy. My students are the next generation of environmental stewards. They live on an island, and many of their families are lobstermen and/or fishermen who rely on the health of the ocean. We are fortunate that our school is located in a beautiful area that borders Acadia National Park and is across the street from Bass Harbor. This allows me to take my students hiking, kayaking, snowshoeing, and exploring the ecosystems all around us.

The health of our ecosystems may be altered in different ways by human impact. It’s vital that my students understand how climate change and coastal flooding may impact their lives in the future. As a NOAA Teacher at Sea, I am excited to bring real-world scientific research into my classroom and inspire my students with firsthand experiences. I look forward to sharing my adventures and discoveries with you, and I hope to ignite a passion for marine science and environmental stewardship in both my students and readers.

Stay tuned for updates from the sea!

Science and Technology Log

Next week, I will board the 209 ft. NOAA Ship Henry B. Bigelow in Newport, Rhode Island.

“The ship is named after Henry Bryant Bigelow (1879-1967), an oceanographer, zoologist, and marine biologist whose work helped establish oceanography as a scientific discipline.” (NOAA OMAO.)

NOAA Ship Henry B. Bigelow “is a fisheries survey vessel built specifically for NOAA to support the study and monitoring of marine fisheries and marine mammals.” (NOAA Ocean Exploration.) The ship conducts both acoustic and trawl surveys and has a wet lab where scientists can collect data about the different species of fish caught.

While aboard NOAA Ship Henry B. Bigelow, I will have the opportunity to deploy a drifting buoy (also known as a drifter) as part of NOAA’s Adopt-a-Drifter Program. The buoy will collect data such as sea surface temperature, salinity, and ocean currents. This data will then be transmitted hourly to orbiting satellites which my students will be able to monitor.

Last week, I attended the University of Maine’s RiSE Coastal TRACERS training.

“The University of Maine-based RiSE Center supports middle and high school students in real-world science research projects, including coastal monitoring and tracking the changes in local ocean water properties, as well as engaging in the design and construction of the sensor units used to collect this data.” (UMaine.)

As part of my training, I toured the “Buoy Barn” at the University of Maine Ocean Observing System (UMOOS). Dr. Neal Pettigrew, professor of oceanography, led the tour while explaining how these moored buoys in the Gulf of Maine help collect data and information about ocean temperatures, salinities, dissolved oxygen, wave heights and periods, and current profiles. “The buoys, designed, fabricated and maintained by Dr. Pettigrew’s team of oceanographers, engineers, computer programmers and research associates, have been transmitting real-time data since 2001.” Such amazing work is happening at the University of Maine!

Science and Technology

As soon as the day group’s shift started at noon we were right into sorting the catch and doing the work-up of weighing, measuring and taking samples.

It’s with a good bit of anticipation waiting to see what the net will reveal when its contents are emptied! There were some new fish for me to see today of which I was able to get some nice photos. I was asked today if I had a favorite fish. I enjoy seeing the variety of star fish that come down the conveyor belt as we sort through the catch even though they are not part of the survey. The Atlantic Mackerel (Scomber scombrus) are beautiful with their blue and black bands on their upper bodies and their shimmering scales. They are a schooling fish and today one catch consisted primarily of this species. I’m fascinated with the unusual looking fish such as the goosefish, the Atlantic wolffish (Anarchichas lupus) with its sharp protruding teeth, and some of the different crabs we have caught in the net. Another catch today, closer to land where the seafloor was more sandy, was full of Atlantic Scallops. Their shells consisted of a variety of interesting colors and patterns.

Today I also had a chance to have a conversation with the Commanding Officer of the Henry B. Bigelow, Commander Jeffrey Taylor. After serving as a medic in the air force, and with a degree in Biology with a concentration in marine zoology from the University of South Florida. What he enjoys about his job is teaching the younger NOAA officers in the operation of the ship. He is proud of his state-of-the-art ship with its advanced technology and engineering and its mission to protect, restore, and manage the marine, coastal and ocean resources. Some things that were touched upon in our conversation about the ship included the winch system for trawling. It is an advanced system that monitors the cable tension and adjusts to keep the net with its sensors open to specific measurements and to keep it on the bottom of the seafloor. This system also is more time efficient. The Hydrographic Winch System deploys the CTD’s before each trawl. CO Taylor also related how the quiet hull and the advanced SONAR systems help in their missions. What we discussed that I am most familiar with since I boarded the Henry B. Bigelow is the Wet Lab, which was especially engineered for the Henry B. Bigelow and its survey missions. This is where I spend a good bit of time during the survey. The ergonomically designed work stations interface with the computer system to record and store the data collected from the fish samples 100% digitally. I was pleased to hear what thought, skill and fine tuning had gone into designing this room as I had earlier on the trip mentally noted some of the interesting aspects of the layout of the room. Commanding Officer Taylor also had high praise for his dedicated NOAA Corps staff and the crew, engineers and scientists that work together as a team.
