Practice Makes Prepared

Life aboard the NOAA Ship Thomas Jefferson is filled with exciting scientific work, but safety is always the top priority. Whether the crew is conducting hydrographic surveys, navigating busy waterways, or working far from shore, everyone on board must be prepared to respond quickly and effectively in an emergency. That preparation comes through regular safety drills and a strong culture of readiness.

Every week, the crew participates in both fire drills and abandon ship drills. In addition, man overboard drills are conducted monthly to ensure everyone remains familiar with emergency procedures. Leading these exercises is Megan McDeavitt, the Damage Control Officer (DCO), who is responsible for planning, coordinating, and evaluating each drill. To keep the crew prepared for real emergencies, the DCO often creates surprise scenarios. During the first fire drill I experienced, simulated smoke was released in a particular area of the ship. Crew members had to adjust their movements and follow alternate routes. These realistic situations challenge the crew to think critically and adapt to changing conditions.

One of the first safety items introduced during orientation is the Emergency Escape Breathing Device (EEBD). An EEBD is located in every room throughout the ship and provides a supply of breathable air that allows individuals to escape from smoke-filled or hazardous environments.

When joining the ship, every crew member receives a billet card that outlines their responsibilities during each type of drill. The sheet identifies primary and secondary muster locations, ensuring everyone knows exactly where to report. The secondary muster station is especially important because emergencies can sometimes block access to the primary location.

Muster instructions are listed below for different scenarios, color coded. Red: Fire & Emergency, Yellow: Abandon Ship, Blue: Marine Overboard. White boxes of different sizes against the colored bars indicate the sound of the emergency signal. Fire & Emergency is one long bar; Abandon Ship is 8 small boxes plus a medium sized box; Marine Overboard is 3 medium boxes. — Billet Card

During a fire drill, the crew reports to their assigned muster stations where attendance is carefully checked. Once a complete muster is attempted, attention turns to any missing personnel. This is where the ship’s medical personnel in charge (MPIC) becomes involved. If a scenario includes an injured or unaccounted-for crew member, responders must locate, assess, and assist that individual while the fire teams continue addressing the simulated emergency.

The Thomas Jefferson maintains three separate fire teams, each trained to respond rapidly to emergencies. Team members must quickly don their firefighting gear, deploy equipment, and establish water to the simulated fire. Working together, the teams communicate their progress while searching affected spaces and ensuring the safety of all personnel.

Abandon ship drills require a different type of preparation. When the abandon ship alarm sounds, crew members must report to their assigned muster station with their life jacket and their immersion suit, often referred to as a “Gumby suit.”

Following every exercise, the DCO conducts a detailed debrief with the crew. During this review, performance metrics are discussed, including how long it took to complete the muster, how quickly each fire team arrived on scene, how fast firefighters dressed in full protective gear, when water was established to fight the fire, and how efficiently missing or injured personnel were located. The crew also examines any challenges encountered during the drill and discusses ways to improve future responses.

Charting a Course for Discovery

Before each leg of operations, there is a briefing. Operations Officer Mark Meadows outlined the goals for the NOAA Ship Thomas Jefferson’s work on Lake Ontario. The mission is to update nautical charts, identify dangers to navigation, and replace outdated survey data collected in the 1940s.

Text superimposed at the top of the map reads: "Existing Data Quality: 1940's, Fathometer, Set Line Spacing @1.5 nm, USACE 2018 nearshore Lidar Data." — The red lines mark the original survey lines from the 1940s.

Many of the original survey lines on Lake Ontario were spaced approximately 1.5 miles apart. While this was considered sufficient at the time, it left vast areas of the lake bottom completely unsurveyed. Modern hydrographic technology allows NOAA to collect much more detailed information, creating safer and more accurate nautical charts for everyone who uses these waters.

The survey efforts also support the Lake Ontario National Marine Sanctuary and the Lakebed 2030 project, an effort to map the entire lake floors by the year 2030. To maximize coverage, the Thomas Jefferson operates nearly around the clock, collecting shipboard data 24 hours a day. During daylight hours, two smaller survey launches focus on nearshore and shallow-water areas that the ship cannot safely access.

The survey team enjoys a little fun when naming the survey sheets. OPS Meadows felt the need to name the nearshore sheets various flavors and heat levels from Dave’s Hot Chicken. Additionally, they decided to divide the midshore sheet into Bert and Ernie. While the names may not appear on the official charts, it added a little humor to the serious business of mapping Lake Ontario.

A Taste of Life on Board

One of the biggest surprises of my Teacher at Sea experience has been the incredible food. Every meal seems to bring something new, and the variety has been nothing short of amazing. In just a short time on board, I have enjoyed rabbit, lamb, gyros, steak, salmon, and even a delicious crawfish boil. Additionally, the desserts are to die for! The rice pudding being my favorite so far. Each meal is thoughtfully prepared, and there is always something to look forward to when the dinner bell rings.

One evening, Chief Steward (CS) Danni Cuff created a stunning croquembouche, which is a towering French dessert made of cream-filled pastry puffs held together with caramelized sugar. It looked like something that belonged in a bakery window rather than on a hydrographic survey vessel in the middle of the Great Lakes. More importantly, it tasted every bit as good as it looked!

The crew aboard Thomas Jefferson also takes condiments very seriously. I am convinced there is every type of condiment imaginable somewhere in the galley. Ketchup, mustard, hot sauces, barbecue sauces, dressings, seasonings. You name it, they probably have it. And not just one version, but multiple brands and varieties. Whatever your taste preference may be, there is likely a condiment waiting to make your meal even better.

The galley always offers a small salad bar stocked with fresh vegetables and toppings. Fresh fruit is also available throughout the day, making it easy to grab a healthy snack between surveys, drills, and shipboard activities. Then there are also tons of unhealthy snack options available as well.

As a Teacher at Sea, sharing meals with crew members from every department makes it easy to get to know people and learn about their unique roles on the ship.

All Lines Away In High Winds

Before the NOAA Ship Thomas Jefferson ever left the Port of Cleveland, the energy on the bridge already reflected that this would not be a routine departure. The navigation team met to review weather forecasts, vessel traffic in the harbor, and the tight physical space of the slip. They walked through the voyage plan for the upcoming transit of the Welland Canal.

The forecast added a layer of challenge: waves building up to 11 feet offshore and wind gusts reaching 40 knots. Even while still tied to the dock, the ship would feel the effects of those winds pushing against the hull. The crew specifically discussed which lines would need to remain in place to best counteract strong winds pushing on the port side. It was a reminder that even leaving the dock is a maneuver that demands planning, not just movement.

After a short rain shower and a two-hour delay, line handlers moved into position along the pier, and the deck team coordinated each step of letting go. The goal was simple in theory but complex in execution. The bridge crew had to free the ship without allowing the stern to swing toward a barge positioned on the starboard side of the ship.

Every action had timing behind it. Lines were released in a deliberate order, engines were brought in carefully, and the rudder responded in small corrections. At the same time, the bridge team monitored traffic on the Cuyahoga River and ensured communication was successful even though it was made difficult in the wind. Amid all of this, Junior Officer James Hutzenbiler had control of the commands, gaining valuable experience managing a complex departure in high winds and restricted maneuvering space. The situation provided a practical test of shiphandling skills under pressure, reinforcing both decision-making and situational awareness in real-world conditions.

What stood out most was not just the difficulty of the conditions, but how smoothly the crew worked through them. Each person understood their role, anticipated the next step, and supported the overall movement of the ship. It was less about individual actions and more about a shared rhythm.

A Stairway between the Great Lakes

The Welland Canal is one of North America’s most impressive feats of marine engineering, linking Lake Ontario and Lake Erie and allowing ships to bypass the powerful and steep Niagara Falls.

The idea of a canal connecting the lakes dates back to the early 19th century, when growing trade made the Niagara Escarpment a major obstacle. The first version of the canal was completed in 1829, but it was narrow, shallow, and quickly outdated as ships grew larger. Over time, the canal was rebuilt and expanded through multiple iterations, with the modern fourth version completed in 1932. Each upgrade reflected advances in engineering and the increasing demands of industrial shipping. Below is an image of the different canal routes over time. The first canal had 40 locks and the current one is down to 8, taking about 9 hours for the Thomas Jefferson to complete.

(The compass rose shows us that on this map, north is to the right, not "up.") solid lines in different colors trace the paths of four canal routes through rivers and streams and cities. above the geographic map is a cross section depiction of the locks showing the changes in elevation from west to east. in the center is a timeline with details about the four version of the canal. — The evolution of the Welland Canal and the current locks.

Transiting the canal is a unique experience for any vessel. Rather than open-water navigation, ships move carefully through a series of eight locks that raise or lower them approximately 326 feet between the two lakes. Each lock demands precision, coordination, and patience. Crews adjust positions and engines in short, controlled bursts to keep the vessel centered as water levels change.

Large cargo ships can use MoorMaster automated vacuum mooring systems to hold the ships in place while in the locks.

However, the Thomas Jefferson has too many port holes for the vacuum to attach. This means the crew is constantly on the bridge adjusting controls to keep the ship off the concrete side walls. It takes an extreme amount of teamwork and concentration. The CO (Commanding Officer) and XO (Executive Officer) found that “crabbing” the ship in at an angle instead of straight in allows for better control.

What stands out most during a transit is the teamwork involved. Every movement onboard is deliberate and communicated clearly. Deckhands, officers, and pilots work in close coordination. Even in tight quarters and changing water levels, there is a steady rhythm to the operation. It is a reminder that successful navigation is not only about technology or infrastructure, but also about people working together with trust and professionalism.

One of the most impressive aspects of the transit was watching the Junior Officers and Operations Officers navigate the entire 12-hour journey through the Welland Canal with only the supervision of the CO and XO.

The Quiet Influence of Great Leaders

One of the most impressive aspects of my time aboard the ship has not been the technology, the navigation, or even the massive engineering feats we encounter. It has been the culture of learning.

Four NOAA Corps officers in blue uniforms stand on an upper deck of NOAA Ship Thomas Jefferson, facing out at the green water. — NOAA Corps officers watch from the flying bridge of NOAA Ship *Thomas Jefferson*

From the moment I stepped aboard, I noticed that the ship operates much like a highly effective classroom. Every day presents opportunities to learn, practice, make mistakes, and improve. What makes this environment so successful is the leadership demonstrated by Commanding Officer Kidd and Executive Officer Duffy. They have fostered a culture where learning is woven into every aspect of daily operations.

After every drill, change of conn, and operational briefing, etc. the leadership team takes time to reflect. Rather than immediately telling crew members what they did right or wrong, they observe, listen, and encourage discussion. Team members are asked to evaluate their own performance, identify challenges, and suggest improvements. This process transforms every event into a learning opportunity.

One example came after Junior Officer James Hutzenbiler successfully guided the ship out of the Port of Cleveland in challenging wind conditions. Once the maneuver was complete, Operations Officer Jessie Spruill gathered the bridge team and asked a simple question: “How do you think that went?” Rather than providing answers, she encouraged the team to analyze their own decisions. The officers discussed what worked well, what could have gone smoother, and what they might do differently next time.

OPS Jessie Spruill then added her own observations and expertise, helping connect their experiences to larger operational concepts. Finally, the XO built upon the discussion, adding further insights and training points that everyone could apply in future situations.

As a teacher, the entire exchange felt remarkably familiar. These are the same instructional strategies educators strive to use in the classroom: reflection, self-assessment, guided discussion, and constructive feedback. The difference is that instead of discussing a math problem or science experiment, the crew was analyzing real-time decisions that affected the safe movement of a ship.

Boarded and Underway

I would be lying if I said I wasn’t nervous about living on a ship for two weeks. Fortunately, those worries began to fade almost as soon as I stepped aboard.

One of the biggest reasons was the people. Everyone has been incredibly welcoming and willing to answer questions, offer advice, and help me navigate life at sea. From the very beginning, the crew made me feel less like a visitor and more like part of the team.

I was especially fortunate to be paired with Junior Officer Bridget Ruiz as my roommate. She had just started her leg aboard the ship as well, which meant we were both experiencing many of the same first-day questions and uncertainties. Having someone to attend orientation with, explore the ship alongside, and compare notes made the transition much easier.

The living quarters were also a pleasant surprise. Before arriving, I imagined a small, cramped room with barely enough space to move around. Instead, our stateroom is surprisingly comfortable, complete with dressers, desks, a sink, a mini refrigerator, and closets for storage.

Of course, shipboard life comes with a few unique experiences. Once the waves started rolling, so did the contents of various tanks throughout the vessel, creating an aroma that can only be described as “memorable.”

Despite the occasional smell and the constant motion beneath my feet, I am quickly settling into the rhythm of shipboard life. Between the incredible views, delicious meals, comfortable accommodations, and supportive crew, I can easily see how people come to love this lifestyle. After only a short time aboard, the ship is already beginning to feel like home.

Introduction

Hello and welcome! My name is Guy (Clark) Sturdevant from Northwest High School in Wichita, KS. You join me as I make final preparations for my two-day journey to Dutch Harbor, Alaska. Once there, I will board the Oscar Dyson and join an amazing science team and crew for a month-long leg of the biennial Eastern Bering Sea Pollock Survey.

As I prepare for this incredible opportunity, I find myself reflecting on the amazing science educators and communicators that helped define my relationship with science. From Mr. Patton’s sixth grade life science class through graduate studies in the department of Geology at the University of Kansas, the passion, character, and enthusiasm of my mentors and teachers was infectious. In my seven years in the classroom, I have worked to immerse my students in the hands-on practice of science. NOAA’s Teacher at Sea Program will be another amazing opportunity for me to learn from world-class scientists and technicians in hopes of bringing the exciting world of marine science into my high school classroom.

Next Monday, I will board NOAA Ship Oscar Dyson in Dutch Harbor, Alaska. The Oscar Dyson is a 208 ft. purpose-built research vessel which hosts the Midwater Assessment & Conservation Engineering (MACE) team for the Summer Pollock Survey. The full survey spans nearly three months and hundreds of nautical miles of the Bering Sea and the Gulf of Alaska.

Oscar’s fame, however, is eclipsed by his wife, Peggy. Peggy Dyson acted as the “Voice of the North Pacific”, broadcasting out marine weather forecasts as WBH-29 twice daily for over 30 years. Her voice served fishing communities in the North Pacific, providing valuable information and a familiar voice across the vast span of the open ocean.

Last Buoy

Deploying the last buoy with my Shipmate Ave Cieplinski

Global drifter buoy #3, a.k.a. LaMonster, for those of the class of 2028 taking my course and ready to learn all about our planet and ocean! We are now in the Gulf of Maine after making our way through Georges Bank, where this drifter was deployed at 40°14.560’N 067°39.008’W on the southernmost station of this region.

The Gulf of Maine is a semi-enclosed sea bordered by Massachusetts, New Hampshire, Maine, New Brunswick and Nova Scotia. Beneath the surface, Georges Bank helps shape currents and separates the Gulf from the Atlantic south of Cape Cod. Just beyond this boundary, the cold Labrador Current and warm Gulf Stream meet. Inside the Gulf, coastal geography redirects these waters, forming a gyre that pushes cold water southward.

Blue arrows depict shallower currents occurring at less than 75 meters deep while red lines depict deeper currents occurring more than 150 meters deep. — Currents Map of the Gulf of Maine (Source: WHOI)

What I find most intriguing is how this balance is shifting; the Labrador Current now carries more freshwater from melting ice, while the Gulf Stream is moving north. These changes matter; many marine species depend on specific temperature ranges, so even small shifts in currents can reshape entire ecosystems. I chose to deploy at this location so that my students will hopefully see the data pattern showing how quickly the drifter moves into the Gulf Stream.

Science and Technology Log

(Source: NOAA Global Drifter Program)

A global drifting buoy, or drifter, is an instrument designed to measure sea surface temperature along with variables such as atmospheric pressure, wind, wave height, and salinity. As these buoys move naturally with ocean currents, onboard sensors collect data and transmit it to satellites, allowing scientists to track their positions over time and map ocean circulation patterns. These drifters provide essential data to validate satellite data and improve forecasts. A critical feature of each drifter is its drogue, or sea anchor, which extends about 20 meters (65 feet) below the surface. Connected by a long tether, the drogue ensures the drifter follows ocean currents rather than being pushed by wind: without it, the instrument would drift like a lightweight object at the surface.

Through our participation in the Adopt a Drifter program, this technology becomes tangible for students. They can follow real drifters and analyze authentic data in near real time; in this way, they’re actively engaging with live information and thinking like scientists as they interpret it. I cannot wait for students to discover the origin story next year! At the time of writing this post, the LaMonster had made its way across a degree of longitude in only a few days.

*Screenshot from the interactive map of the Global Drifter Program (GDP) Array*

The data generated by these drifters are compiled into a comprehensive dataset providing hourly estimates of sea surface temperature and ocean currents. The buoys last around 400 days but scientists are already trying to improve the power capability, read here. Managed and quality-controlled by NOAA’s Drifter Data Assembly Center (DAC) at the Atlantic Oceanographic and Meteorological Laboratory (AOML), the dataset ensures accuracy and consistency. Rich metadata, such as deployment details, drogue status, drifter type, and identification information, further supports meaningful analysis and real-world scientific investigation such as used here.

Meet Nick Vang, a survey tech with NOAA currently serving as an augmenter, a role in which he not only runs operations in the acoustics lab but also coordinates with the science team, deck crew and bridge to ensure the execution of the mission runs smoothly. I just love that title “augmenter” and have decided to use it next in lieu of “teacher” ( I’m kind of joking, but not really; I probably will work it in at some point). This is because we know that, as teachers, we are not just running operations in one particular room on one particular day, but rather focusing on the bigger picture of the whole school year as our mission.

In the acoustics lab, the EM2040 is a high-resolution scientific multibeam sonar system used to collect detailed data from both the water column and the ocean floor. In simple terms, the system works by sending out a cone-shaped sound wave, often called a “ping”, toward the seafloor down to 300 meters. This sound reflects off the ocean bottom and returns to the ship, allowing onboard computers to calculate the distance traveled. From this information, a map of the seafloor begins to take shape.

The survey tech team refines the raw data by correcting factors such as tides, sound speed and vessel offset, ensuring the measurements align accurately. The techs go through a training program when hired that is specific to using the software used by NOAA ships. One area in which software has advanced is its ability to read any “noise” that is not the actual bottom and compute the depth accurately. The processed data is then transformed into a bathymetric model, a detailed representation of the seafloor, which is used to precisely determine optimal station locations.

The Pisces operates as a diesel-electric vessel, similar in concept to a hybrid car, thereby reducing emissions and supporting NOAA’s goal of achieving net-zero emissions by 2050. The vessel is also equipped with a bow thruster, which is especially useful when holding position. This system works with the dynamic positioning system to keep Pisces precisely in place, counteracting currents and eliminating drift.

We took a tour of the engine room and Chief Engineer Adam Butters guided us through some of the key systems that keep the ship running. The engines and equipment were impressive, and it was clear that the engineering team put in a lot of work to make our mission possible. The engine room was very loud and hot; we wore earplugs for protection, but I could not hear myself think. We started at the water maker unit, which uses reverse osmosis (RO), which turns ocean water into fresh water for drinking, cooking and bathing. Fun fact: this removes all the minerals from the water, so I added an electrolyte mix to my water bottle each day.

Next, he showed us the systems that support the lab. He pointed out the refrigeration system that keeps chlorophyll samples frozen at -80°C. It was interesting to see the equipment that powers everything behind the scenes. The ship’s electrical system is also complex, producing 600 volts of electricity, which is stepped down to power large machines and even further for everyday outlets like the ones in our rooms. In addition, we saw a centrifuge that cleans diesel fuel by separating impurities and water using specific gravity.

For me, it was an honor to chat with the commissioned NOAA officers aboard for this survey. My visit to the Bridge included a demonstration of the sextant lesson CO plans to teach as the ship makes its next sail to the Canary Islands, instructions for some of the basics in driving the ship and an explanation of how to read the ship’s navigational screen during sample station deployments.

I’ve learned that the NOAA Commissioned Officer Corps (NOAA Corps) is one of the nation’s eight uniformed services and its officers play a key role in carrying out NOAA’s mission. With a relatively small group, about 360 officers, they support a wide range of scientific and operational programs both at sea and in the air.

While some officers earn a 4-year STEM-based degree, others attend maritime colleges that offer personalized education with career-ready placements. After being selected, officer candidates train at the NOAA Corps Training Center at the U.S. Coast Guard Academy before being commissioned as ensigns. From there, many begin their careers at sea, with about 80 percent of officers serving aboard NOAA ships at some point.

What stood out to me most is the variety in their careers. Officers rotate between sea, aviation, and land assignments every few years, building experience in different roles while supporting NOAA’s work from multiple angles.

First Light Timelapse

I continue to be absolutely amazed at the first light of each day. Each morning, I determine the travel orientation of this ship and which deck, bow or stern, port or starboard, I should visit for the best view.

And the food in the galley continues to be excellent, I had a chance to chat with both cooks (Mike x2) and they both absolutely are very appreciated by the crew. Mealtimes on the ship are special, as nearly everyone stops their tasks for a welcome break and nourishment. Several times, the bridge would announce over the radio that they were holding the start of the station until after mealtime.

Did You Know?

My students are familiar with Marine Protected Areas (MPAs) as I open the year by teaching about them, that while the world has ONE ocean, I highlight the importance of designating our oceans as distinct sections. The MPA distinction allows students to jump right in, looking at some of the charismatic marine fauna and learning what it means to be a stakeholder. Below is a map of the MPAs located within our national waters and an overview of Stellwagen Bank, a sanctuary where we conducted some of our samplings.

The nutrient-rich waters of Stellwagen Bank have long made it a cornerstone of New England’s maritime story, supporting productive fisheries and returning whales, making it a whale-watching destination. This is where I was able to witness mother-calf pairs forage and learn with security and protection. This ecological vibrancy highlights the power of marine protected areas to sustain both wildlife and human use. Within federal waters, the 842-square-mile sanctuary stretches from south of Cape Ann to north of Cape Cod and is New England’s only national marine sanctuary.

Animal monitoring is an exciting part of life aboard our research vessel. It doesn’t take much to spark enthusiasm; an alert comes over the radio (not the loudspeaker because we don’t want to wake the sleeping crew!) about animals sighted near the boat, and the crew pops up to the deck (no, it’s not just Mrs. LaMonte), eager for a glimpse of these charismatic marine visitors. Nick Metheny is the dedicated observer for the Pisces on this cruise survey. He is observing and documenting from sunrise to sunset; that’s some dedication! Meanwhile, NOAA Corps officers on the bridge keep a steady, watchful eye to ensure we safely share these waters with much larger neighbors, including whales.

Beyond these spontaneous moments of excitement, Seabird and Marine Mammal Observers play a critical, structured role within our science team. From their perch on the Flying Bridge, they scan the horizon, tracking everything. Each sighting, species, group size, behavior and any photograph is carefully recorded and cataloged.

These data feed into long-term monitoring efforts, including AMAPPS (the Atlantic Marine Assessment Program for Protected Species). Through this work, NOAA scientists are building a clearer picture of how whales, dolphins, sea turtles, and seabirds move through and rely on these waters. It’s rewarding to know that those thrilling, real-time sightings of these incredible animals are also contributing to critical research, helping us better understand and protect the vibrant marine life that makes every watch on deck feel a little bit magical.

You are likely familiar with the satellites of the National Aeronautics and Space Administration (NASA), although high-tech, the satellites must be carefully validated. During the NOAA EcoMon cruise, we’re helping to ground-truth NASA’s PACE satellite, which monitors phytoplankton. Artem Dzhulai and Rowan Cirivello are Ph.D. candidates in biological oceanography who study how light interacts with the ocean. When the NASA satellite passes over our ship at noon, they deploy a radiometer to measure how light decreases through the water column.

They also collect water samples, either from CTD Rosette casts or the ship’s continuous water line system (more about that in the next blog). In the lab, the samples are filtered to separate particulate matter (such as plankton) and colored dissolved organic matter (CDOM). This is done repeatedly for validation or “triplicates for particulates,” as Rowan puts it. These are analyzed with a spectrophotometer to determine how light and color vary in the water, with some samples sent directly to NASA.

Advances in technology now allow us to deploy sophisticated instruments that can continuously track individual organisms in the ocean. Two Imaging FlowCytoBots (IFCB) are being used to confirm accuracy. Inside the cylinder tanks, images of individual plankton are taken with thresholds set based on backscattering & fluorescence; for example, lower the threshold for pelagic water with fewer organisms and increase it for neritic (coastal) water with a higher abundance of organisms.

Look at how cool it is to see the phytoplankton in real-time!

With these tools, we are not just observing ecosystems, we are witnessing them unfold in real time, opening the door to deeper insight, discovery and innovation in marine science. Ultimately, this work improves our understanding of ocean health and could help fisheries identify productive ecosystems by tracking phytoplankton, the foundation of the marine food web.

Scientific Concepts

Below are some terms you may have learned in a science class before, but are key to understanding why the measurements are being collected as data for the EcoMon survey samples. These parameters, along with nutrients and oxygen, determine the types and abundance of plankton.

Plankton – Don’t doubt the drifters, plankton run the world. Despite their name, rooted in the Greek planktos, meaning “wanderer” because they cannot swim against the current, these tiny powerhouses are anything but passive. They are dynamic, influential forces that quietly orchestrate life on a global scale. From fueling marine food webs to regulating the carbon cycle and even shaping weather patterns, plankton prove that impact isn’t about size, it’s about significance.

Temperature, salinity and density vary with depth – below is a general graph of how scientists might expect parameters to change with depth. In addition to this general trend, scientists will layer in information about a specific location to account for variables such as bathymetry (underwater topography) and latitude. By understanding these general trends, they can determine when changes occur and how they may impact plankton.

Conductivity (salinity) – Pure water conducts electricity very poorly. However, when salts such as sodium chloride (NaCl) dissolve, they dissociate into free-moving, charged ions that readily conduct an electric current. As a result, increasing salinity corresponds to higher electrical conductivity. A CTD instrument captures this relationship using a conductivity sensor, which measures how effectively the water transmits an electrical current, a direct reflection of its dissolved salt and ion content.

Fluorescence – Oceanographers rely on chlorophyll (a) fluorescence as a primary biological proxy to estimate phytoplankton concentration and biomass. Phytoplankton cells absorb blue light and re-emit the absorbed energy as red fluorescence (at around 685 nm), which can be efficiently measured and graphed.

Methodology

The Conductivity, Temperature, and Depth (CTD) is an instrument with several physical and chemical sensors: pH, temperature, salinity, oxygen, depth, and fluorescence that collects data at every station from which we collected fisheries data. On the ship, there are two CTDs: one is attached between the bongos and one is attached at the bottom of the Rosette (a circular instrument with bottles for collecting water samples). Depending on the station’s criteria, both are sometimes deployed.

For this instrument, the ship must be diligent in following protocol; one important job for the Able Body Deck Crew is getting the instrument into the water and maintaining the guidelines for the cable lines’ angle and depth. The NOAA Corps officers radio from the bridge, “10 minutes until bongo” (I have heard this 100’s of times) and the crew begins operations.

In addition to deployment, there are two tasks for this instrument to be completed by the science team: monitoring its deployment in the lab as some data is transmitted instantly and retrieving the water samples that will be processed for additional lab data.

Open valves for the cylinder

This data is used alongside catch data collected from the bongos, allowing scientists to make connections between water quality and fish caught. While the relationship is complex, water quality and marine life abundance are directly related. Water quality and the survivability of marine species contribute to our economic, cultural and public health. This data can help identify potential threats and inform management plans for both water quality and targeted species.

The NOAA Ship Pisces has been so welcoming to me as I have become fully immersed in the ship’s daily routine. There is a bulletin board with pictures of the people currently onboard, you can see I am part of the science team, most of whom I have written about or will write about. They even posted a QR to my blog and some of the crew have read along and learned the details of some of the science being conducted onboard. Have I mentioned how much I LOVE the FIRST LIGHT of the day! Just breathtaking. I feel like I am working and on vacation at the same time. For work, I bounce back and forth between washing bongo nets, writing the blog, posting student challenges on Instagram and watching for wildlife. Getting to see so many marine organisms, having delicious choices for breakfast/lunch (also good choices for dinner, but 3 am-3 pm shift, I am already in bed) ready for me and getting to do laundry while I work definitely feels like vacay mode.

Did You Know?

That beautiful Caribbean blue water could be seen from the NASA satellites and it was caused by microscopic phytoplankton. Plankton, specifically phytoplankton, really are in charge! I actually pranked several students into thinking the ship was down in the islands.

Coccolithophores span a broad range of surface environments, from nutrient-rich (eutrophic) waters in temperate and subpolar regions to persistently nutrient-poor (oligotrophic) subtropical gyres. They contribute about 1–10% of primary production and phytoplankton biomass, with their share rising to ~40% during bloom conditions.

Coccolithophores are among the most significant pelagic calcifiers, producing large quantities of calcium carbonate. The shedding drives a sustained flux of carbonate to the deep ocean, supporting vertical gradients in seawater alkalinity and playing a key role in the carbonate pump. In addition, coccoliths enhance the sinking rate of organic matter and improve the efficiency of carbon export to depth. Over long timescales, this has contributed to the formation of a carbon sink; feedbacks between seafloor carbonate accumulation and the carbon cycle help stabilize Earth’s climate.
