Introduction

Hello, my name is Sam Garson and I am thrilled to be a part of this year’s cohort of Teachers at Sea! I teach science and CTE STEM courses at Friday Harbor High School (FHHS) on an island off the coast of Washington State named San Juan Island. I teach AP Biology, AP Chemistry, Anatomy & Physiology, AP Computer Science Principles, AP Computer Science A, Robotics, Electric Vehicle Principles, Project Management and 3D Design and Fabrication… rural science education is no joke, folks.

I have been involved with education for 20 years now in roles from a substitute teacher in Miami, Florida to an education programs coordinator with a program not so dissimilar from the NOAA TAS program. In my current role as a rural remote educator, I push students to think about the world in terms well beyond their trips to “America” (the mainland), and instead adopt a “Glocal” perspective of thinking globally and acting locally.

Teaching science is something that I am incredibly passionate about, and I have worked hard to help my students realize the amazing STEM pathways that exist in today’s world. Especially now in my rural community, I want my students to see STEM as the gateway to a world economy desperate for their creativity, ingenuity and problem-solving skills. I strive to bring the real world into my classroom and allow my students to try and solve the issues they see in the world around them and ask BIG questions of what could be.

This past year, students from FHHS found themselves designing a radiation sensor for a NASA and World View high altitude balloon mission while being named State Finalists for Samsung’s Solve for Tomorrow Challenge.

I am thrilled to be able to show students a piece of the world that many of them have probably never thought about, and share with them the excitement of real world research, data collection and all the amazing technology, teamwork and collaboration among a host of different STEM careers that go into making this sort of survey possible.

Science and Technology Log

In just a few days time, I’ll be lucky enough to be back at sea aboard the NOAA Ship Henry B. Bigelow sailing out of Newport, Rhode Island. The Bottom Trawl survey operates along the Northwest Atlantic continental shelf, sampling at stations from Cape Lookout, North Carolina to Canada’s Scotian Shelf (NOAA Fisheries). This survey is actually the longest running of its kind in the world! There are more than 60 years worth of data from these surveys. Given the dynamic nature of climate change and ocean acidification, this data is needed more than ever.

The amount of cooperating technology, science and engineering that goes into a mission like this is truly incredible. I’m excited to be in a position to share the people, science and data that we collect over the next three weeks.

Personal Log

This cruise is an exciting and slightly strange one for me to participate in due to a few interesting coincidences. The first one that struck me was that I am a graduate of Henry B. Bigelow Middle School in Newton, Massachusetts. A name that, unless I have forgotten, the significance of was never revealed to me as a student there.

Perhaps the most striking coincidence with this cruise is the return to Rhode Island. As a new teacher in Seattle, Washington 15 years ago, I was one of the inaugural members of the Ocean Exploration Trust’s Teacher at Sea program. I had participated in a Research Experience for Teachers (RET) with the Fred Hutchinson Cancer Research program earlier that year and was alerted to this new opportunity by a colleague. What followed was 7 years of work with the Ocean Exploration Trust helping to take students and teachers out to sea on the E/V Nautilus.

That time in my career was incredibly transformative and the educational tools and values I developed there have been central to my pedagogy as a teacher in the 9 years since I left and returned to the classroom in Friday Harbor. I have tried to show my students how far and wide STEM can take you and all the different stories of people in those STEM fields.

I am thrilled to return to sea with a very different type of expedition. Exploration is a key aspect of our understanding of the world’s oceans, but this opportunity to be a part of a longitudinal study to help understand the ecosystems and fauna present on the Northeast Coast is one that I am thrilled to be embarking on.

Monitoring Ocean Parameters with NOAA’s CTD and Carousel Bottle Sampler

The CTD and Carousel Sampler are essential tools NOAA uses to monitor ocean conditions. “CTD” stands for Conductivity, Temperature, and Depth, the primary parameters this device measures. By running profiles of the water column from the surface to the bottom, the CTD helps us understand key ocean characteristics. The Carousel Sampler paired with the CTD allows collection of water samples at depth for laboratory analysis.

What Does the CTD Measure?

  • Conductivity: Helps determine the salinity of the water.
  • Temperature: Measures the thermal profile of the water column.
  • Depth: Tracks how deep the CTD is during data collection.

Together, these measurements give us a detailed profile of the water column, helping scientists monitor what we call “the Big Four” parameters.

Carousel: Collecting Water Samples

The CTD and Carousel is equipped with twelve Niskin bottles, which are used to collect discrete water samples from specific depths. The bottles are numbered 1-12, and are “fired” (closed) at different depths to capture water samples.

For example, bottle 1 might be fired near the bottom (a few meters above the seafloor), bottle 2 at 10 meters, bottle 3 at the determined chlorophyll maximum (C Max), and bottle 4 couple just below the surface. Multiple bottles are often fired at each depth to collect additional water. These samples provide critical data about the ocean’s chemical properties at various levels.

The bottles have opened stoppers connected at the top and bottom. the CTD probe, at the center of the round, is not visible. Tonya has added yellow text boxes to label the following: carousel, Niskin bottles, top stopper, valves, bottom stopper.

Preparing the CTD Carousel Bottle Sampler

Before deployment, we ensure that all the stopper valves at the top and bottom of each Niskin bottle are closed. We also hook the wires at the top and bottom to prepare the bottles to open at the designated depths. Once the CTD is ready, it is carefully lowered into the water, beginning its descent through the water column.

Analyzing the Key Parameters

Once the water samples are retrieved, we focus on analyzing these key parameters:

  • Dissolved Inorganic Carbon (DIC)
  • pH
  • Total Alkalinity (TA)
  • Nutrients
  • Chlorophyll

Nutrients and Chlorophyll stored in freezer at -80°C.

Storing the Samples

After processing, the nutrient and chlorophyll samples are stored in a freezer kept at -80°C (-112°F) to preserve them for further analysis. Mercuric chloride is added to the DIC, pH, and TA samples to preserve them until they are measured in the laboratory. These samples provide invaluable insights into ocean health. The DIC, TA and pH samples help us monitor the effects effects of ocean acidification— which occurs when carbon dioxide dissolves into the ocean. The chlorophyll samples measure the amount of phytoplankton living in the water. Like plants on land, microscopic phytoplankton carry out photosynthesis, produce oxygen, and are at the base of the marine food web.

Understanding these parameters allows us to monitor the ocean’s health and better predict how it may change in the future. For more information on ocean acidification, check out this resource: NOAA Ocean Acidification.

By closely monitoring DIC, TA and pH we can track important changes in our oceans, providing critical data for research and conservation efforts.

Life on a 12-Hour Work Shift at Sea

Working a 12-hour shift at sea might sound intense, but there’s often some downtime between stations and even a few hours after the work is done. The time you get can vary depending on how far apart each station is. Sometimes it’s just enough to process samples before heading to the next station, while other times you have several hours to relax and recharge.

So, how do you spend that free time on a ship? There’s no shortage of options. You could enjoy a movie in the lounge area, dive into a good book, play a board or card game with other crew members, or head to the flying deck to spot seabirds and marine life, or simply take in the stunning ocean views. Another interesting way to pass the time is visiting the bridge, where you can see how the ship is navigated, maneuvered, and commanded.

Let’s not forget “Activities and Crafts with Katy,” which can bring a whole new adventure to your day. Today, this included visiting the lab and looking at the different species of marine organisms that have been collected, such as stingray barbs, dogfish, and scallop shells. Katy then showed us how to make our own Acadian Redfish otolith (ear bone) earrings. “Scientists use the ear stones (bones) as a way to age the fish. Also called otoliths, they are bones found right behind the skulls of bony fishes.” (Smithsonian)

The balance of work and downtime can make those long shifts much more manageable and even enjoyable, offering moments to connect with colleagues and the environment around you in a way that few people get to experience.

Did You Know?

“One atmosphere is equal to the weight of the earth’s atmosphere at sea level, about 14.6 pounds per square inch” (NOAA Water Pressures at Ocean Depths). Beneath the ocean’s surface, water pressure increases by approximately one atmosphere for every 10 meters of depth.

To illustrate just how intense this pressure can be, we conducted a simple yet fascinating experiment. We decorated 16 ounce styrofoam cups with artwork, then placed them in a mesh bag attached to the CTD Carousel Sampler. The CTD , along with the cups, was submerged to a depth of about 500 meters (1640.42 feet), where the pressure equals roughly 725 pounds per square inch (psi). We repeated this process by submerging the cups to 200 meters (656.17 feet), which equals about 291.18 psi.

As the cups descended into the depths, the increasing water pressure caused them to shrink dramatically because the air inside the cups was compressed. This simple experiment vividly demonstrates how powerful the forces at play beneath the ocean’s surface can be.

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).

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:

View from a side deck of NOAA Ship Bigelow as chain lowers nets into the water; the openings of the nets are two large round circles, and the fine mesh plankton nets extend down in cones from each ring. Two crewmembers wearing hard hats and life vests stand at the rail to guide the nets down. It is sunset, and the sun is almost at the horizon, creating a band of bright orange between the dark blue water and sky.

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.
Emma Venarde (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!

Three people lean over clumps of seagrasses in a tide pool area. They have placed a one meter square of PVC pipe down on the grasses. Two of them use a measuring tape while another picks through the grass. A purple sample bucket with a plastic bag and laminated identification sheets sits off to the side. The people wear high-visibility vests.

The light itself is painted white, with a black top, and nearby are a few additional buildings that are white with red roofs. The cluster of buildings is surrounded by tall conifers. The sky is blue with a few fluffy white clouds.

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.

Personal Log

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!

Two large buoys in a storage shed. They are wide and round at the bottom, to float in the ocean, and towers of sensors and equipment extend upward from each base. The buoys are painted mostly yellow, with blue bottoms and blue lettering: the left buoy reads NOAA and the right reads UPRM.

a large buoy in a storage shed (flanked by other buoys and equipment, only partially visible.) It are wide and round at the bottom, to float in the ocean, and towers of sensors and equipment extend upward from the base. The buoy is painted mostly yellow, with blue bottom and blue lettering: the buoy reads NOAA 41052. The word CariCOOS is visible in smaller letters on the tower portion.

this vessel looks like a small sailboat, one too small to fit people. in fact, the hull is covered completely (no room for seating) and dotted with solar panels. The hull is red, and the sails are white and orange. It's inside a storage shed, and ocean buoys are partially visible behind it.

Automated Surface Vessel
ocean monitoring equipment in a storage shed; this glider is shaped a bit like a small airplane (aerodynamic body, wings, tail.) It's stored on a small trailer or cart with wheels, on top of a bench.
