Beyond Ocean Mapping: Using Uncrewed Vehicles to Advance Ocean Research

August 21, 2026 —  It’s January off of Nantucket Shoals. An uncrewed surface vehicle begins a series of carefully planned transects through Southern New England, collecting data day and night. There are no scientists onboard, but the 30-foot vessel is constantly measuring ocean currents, water temperature, salinity, weather and other ocean conditions. It’s also helping identify areas with high fish and plankton abundance. Every nautical mile traveled adds to a more complete picture of how marine ecosystems function.

These missions reflect NOAA’s growing use of uncrewed systems technology. Traditionally, these autonomous platforms have supported hydrographic surveys, nautical charting, and ocean mapping. But the benefits extend beyond creating better maps. Today, the same technologies are helping scientists answer complex ecological and oceanographic questions. They’re collecting critical, high-accuracy, and time-sensitive data across nearly every mission area.

“Over the last several years, we have been able to expand the applications for how uncrewed surface vehicles can help with various research related to stock, ecosystem, and protected species evaluations and assessments,” explains Dr. Conor McManus, marine development and advanced technology program lead for the Northeast Fisheries Science Center. “With each mission we conduct, we are learning more about the Northeast U.S. Shelf ecosystem, but also how we can better operationalize these technologies to meet our scientific or data needs.”

These technological advances are expanding where, when, and how our scientists collect ocean data. The results allow researchers to observe the ocean more continuously and in places that are difficult to sample with ships alone. These vehicles complement ship-based surveys—filling gaps in data that can arise from challenges like winter weather and limited ship availability.

This year, there were three uncrewed surface vehicle missions in the Northeast—two operated by Chance Maritime Technologies and one using DriX. They demonstrated how the benefits of uncrewed survey technology can answer many different scientific questions.

WHOI Led Research Team to Develop System to Predict Changes in Ocean Temps

October 30, 2017 — WOODS HOLE, Mass. — A research team led by the Woods Hole Oceanographic Institution has received a federal grant to develop a system to predict changes in ocean temperature.

The system will estimate seasonal and year-to-year temperature changes in the Northeast U.S. Shelf, which is seeing some of the highest ocean warming rates in the world and is home to a highly productive and commercially important marine ecosystem.

The Northeast Fisheries Science Center in Woods Hole and Stony Brook University are also part of the research team.

“Changes in ocean temperature hugely impacts the living organisms in coastal waters,” said Young-Oh Kwon, an associate scientist in WHOI’s Physical Oceanography Department and lead investigator of the new project.

NOAA Warns of Continuing Species Shifts Due to Warming Oceans

May 19, 2017 — Scientists using a high-resolution global climate model and historical observations of species distributions on the Northeast U.S. Shelf have found that commercially important species will continue to shift their distribution as ocean waters warm two to three times faster than the global average through the end of this century. Projected increases in surface to bottom waters of 6.6 to 9 degrees F (3.7 to 5.0 degrees Celsius) from current conditions are expected.

The findings, reported in Progress in Oceanography, suggest ocean temperature will continue to play a major role in where commercially important species will find suitable habitat. Sea surface temperatures in the Gulf of Maine have warmed faster than 99 percent of the global ocean over the past decade. Northward shifts of many species are already happening, with major changes expected in the complex of species occurring in different regions on the shelf, and shifts from one management jurisdiction to another. These changes will directly affect fishing communities, as species now landed at those ports move out of range, and new species move in.

“Species that are currently found in the Mid-Atlantic Bight and on Georges Bank may have enough suitable habitat in the future because they can shift northward as temperatures increase,” said lead author Kristin Kleisner, formerly of the Northeast Fisheries Science Center (NEFSC)’s Ecosystems Dynamics and Assessment Branch and now a senior scientist at the Environmental Defense Fund. “Species concentrated in the Gulf of Maine, where species have shifted to deeper water rather than northward, may be more likely to experience a significant decline in suitable habitat and move out of the region altogether.”
