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.

ALASKA: Deep sea mining in the Gulf of Alaska

August 13, 2026 — With China reportedly producing around 90 percent of the world’s supply of rare earth elements, and far ahead in processing technology, the U.S. and other countries are searching for new ways to meet demand, and deep sea mining on seamounts in the Gulf of Alaska is on the list of proposals. The Japanese press reported in July that experimental deep sea mining had successfully extracted rare earth elements such as neodymium, dysprosium, and terbium—all vital for fighter jet and missile guidance systems—from 6,000 feet below the surface.

In April of 2025, President Trump issued Executive Order 14285 “Unleashing America’s Offshore Critical Minerals and Resources,” and the Bureau of Ocean Energy Management (BOEM) is evaluating whether to advance a competitive lease sale for minerals on the Alaska Outer Continental Shelf. “We don’t know what impact deep sea mining could have on fisheries, but there is cause for concern,” says retired University of Alaska marine professor Rick Steiner, who now runs a consulting company called Oasis Earth.

Trump administration ends NOAA support for annual Arctic Report Card

August 13, 2026 — The Trump administration has pulled federal support from the Arctic Report Card, an annual, peer-reviewed report that has been published by the National Oceanic and Atmospheric Administration since 2006.

NOAA will no longer provide administrative support for the report, though NOAA scientists and programs will continue to collect climate data, said a statement released by the agency on Tuesday.

“Coordination of the 2026 Arctic Report Card will not be facilitated through NOAA,” the statement said. “All data historically contributed by NOAA to the product will continue to be collected and will remain publicly available.”

El Niño Alters Marine Life in the Pacific

August 11, 2026 — As of June 2026, El Niño has officially arrived. This naturally recurring phenomenon is characterized by warmer-than-normal water temperatures in parts of the equatorial Pacific along with changes to atmospheric and oceanic circulation patterns. Its regional effects range from desert floods to delayed monsoons to shifts in where tropical cyclones are more likely to form.

NOAA’s Climate Prediction Center expects the current El Niño to continue to strengthen through the end of 2026, with a 97 percent chance of lasting through early Northern Hemisphere spring 2027. Even during El Niño’s early stages, satellites have observed characteristic changes along the equatorial Pacific, such as warmer-than-normal sea surface temperatures and higher-than-normal sea surface height.

Among the first ecological downstream effects are changes to the marine food web. The maps above show chlorophyll-a concentrations—the pigment present in most phytoplankton—as observed by the OCI (Ocean Color Instrument) on NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) satellite. In June 2025 (left), conditions were neutral, while in June 2026 (right), El Niño was strengthening.

MASSACHUSETTS: A challenging but ‘priceless’ life of a lobsterman

August 3, 2026 — A lot has changed since Tom O’Reilly threw his first lobster pot in the ocean more than four decades ago.

Back then he was using wooden traps which had to be laden with rocks so they would sink to the sea floor. Once the wood became waterlogged the rocks were no longer needed, but they were heavy even when empty. Each pot was hauled up one at a time using only muscle power, a slow and arduous task. And he worked year ‘round.

Now 65, O’Reilly – a big, affable man with short cropped white hair and piercing blue eyes – employs a “stern man,” currently 18-year-old Kyle Moyen, of Manomet. Wooden traps have been replaced by lighter, coated wire traps strung together in groups of 15, each separated from the others by 90 feet of rope. To get the traps up to the boat, Moyen uses a grappling hook to grab the rope just underneath each buoy and O’Reilly threads the rope onto a winch-like device mounted on the starboard rail. He calls it a hauler (brand name: Hydro Slave) and it does most the heavy lifting until each trap is brought alongside the boat where Moyen wrangles it onto the rail. As for lobster fishing year ‘round, that, to O’Reilly’s chagrin, has been reduced by state regulation to help save the endangered North Atlantic right whale, of which fewer than 400 remain.

When I moved to Plymouth in late 2024, I was surprised the following spring to see so many lobster buoys bobbing in Plymouth waters. It was widely reported that even Maine’s coastal waters were becoming too warm to sustain the lobster population, forcing them north into Canadian waters.

According to the National Oceanic and Atmospheric Administration (NOAA), the waters of Cape Cod Bay and the Gulf of Maine, of which Cape Cod Bay is a part, are warming faster than most global marine environments. The Woods Hole Oceanographic Institute concludes climate change has caused average summertime water temperatures in the Bay to warm by more than 3.5 degrees Fahrenheit since the 1970s. That may not sound like a lot, but even a one-degree average rise can mean the difference between thriving and dying for some species. Local oystermen cite warming waters for a drastic reduction in the local mussel population, for example.

O’Reilly doesn’t dispute the data, but says over the past ten years the temperature has been stable.

“People may disagree with me on this,” O’Reilly says, “but I’ve monitored the water temperature every day for the past ten years, and I don’t see it rising.”

He points to one of the monitors on his boat, the 36-foot Karen M, built in Maine in 1991 and named for O’Reilly’s wife. The monitor shows the water temperature is 65 degrees. “Normally, this time of year, it should be about 70,” he says, “and the lobster population is stable.”

Chinook salmon in decline, worsened by Bering Sea heatwave a decade ago: study

July 30, 2026 — Yukon River Chinook salmon numbers have been in a decline for decades. Despite efforts to help the population recover, it has dropped nearly 90 per cent since the 1980s.

Now, a new study from the National Oceanic Atmospheric Administration (NOAA) says a four-year heatwave in the Bering Sea that started about a decade ago has been connected to a more recent drop in population.

Curry Cunningham, one of the co-authors of the study and an associate professor with the University of Alaska Fairbanks, said researchers have noticed two periods of decline in the Chinook salmon population between 2003 and 2023.

Cunningham said before 2013, the salmon experienced a short decline followed by a few years of recovery.

But by 2016, conditions started to change again.

“That’s led to this very depressed state we currently find ourselves in,” Cunningham said. “[It] seems to be associated in time, at least with the onset of this marine heat wave that we saw in the eastern Bering Sea.”

NOAA Report Finds Gulf of Maine Warming Slowed for Now, but Ecosystem Remains Unstable

July 28, 2026 — Maine’s fishing ports are doing well for now, but climate change is destabilizing the Gulf of Maine, according to the National Oceanic and Atmospheric Administration’s latest “State of the Ecosystem” report for New England waters. Federal scientists presented the report to the New England Fishery Management Council in April, and published it online last week.

They found that some Maine fishing ports are growing busier, likely driven by the high price of lobster. Stonington, Harpswell and Friendship all see more activity now than they did roughly 20 years ago.

And 2025, like 2024, offered slightly cooler water temperatures after more than a decade of rapid and record-breaking warming in the Gulf of Maine. But the scientists predict that temperatures will warm again this fall, and will continue to rise long-term as the burning of fossil fuels releases greenhouse gases into the atmosphere.

To weather these ongoing changes, fishermen and their communities need to diversify their businesses, experts say.

“Things don’t look particularly stable either in terms of the fishery or the ecosystem,” said Joseph Caracappa, a research biologist at NOAA’s Northeast Fisheries Science Center who edited the report. “We’re seeing big changes that are sweeping across the ecology of the system and fisheries. Even socially, culturally — how communities are structured, where people are fishing, who’s actually doing the fishing.”

This annual report includes contributions from more than 100 scientists across the Northeast. NOAA has had to make do with fewer resources as the federal government’s priorities have changed under the second Trump administration, but otherwise the report has been prepared and published as usual, Caracappa said. And in fact, this latest report debuted a new section dedicated to forecasting ocean conditions in the year ahead.

New report finds temporary relief for warming Gulf of Maine

July 27, 2026 — Cooler weather in the past 2 years offered some relief to the rapidly warming Gulf of Maine, but it’s not expected to stay that way.

That’s according to the National Oceanic and Atmospheric Administration’s (NOAA) latest “State of the Ecosystem” report on New England’s waters, which was released online last week, and previously presented to the New England Fishery Management Council in April.

While the report found slightly cooler water temperatures in 2024 and 2025, the warming trend is expected to come back this fall and continue to rise long term due to climate change. Scientists attribute the trend to the Gulf Stream, which brings warm water up from the Gulf Mexico, appearing to be getting stronger than in years past.
