For this post, I tried to step aside from my biologist bias (it was an insightful challenge) and highlight the technical aspects of running an ecosystem science operation. I have provided numerous links to illustrate the path to various careers and future research being conducted with NOAA.
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.
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.
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.
Methodology & Careers

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.
Personal Log
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.
