NFSC used uncrewed vessel to bolster New England fisheries survey

August 20, 2025 — The Northeast Fisheries Science Center used a DriX uncrewed vessel to complement its survey of southern New England fisheries this spring, with the small drone collecting data that would be difficult for traditional research vessels to gather.

NOAA Fisheries has promoted the use of uncrewed systems as an emerging technology that can be used to overcome several challenges to federal government fisheries surveys. Advocates say the autonomous vessels can navigate in areas where larger vessels can’t operate, such as in and around the increasing number of offshore wind developments. While those installations have threatened to disrupt NOAA Fisheries long-term data collection efforts, researchers believe drones can help fill the gaps in data collection.

Uncrewed Vehicle Helps Fill Data Gaps in Northeast’s Difficult-to-Reach Areas

August 19, 2025 — Between April 16 and May 5, 2025, a team of ocean researchers conducted the Northeast Fisheries Science Center’s second DriX survey out of Narragansett Bay, Rhode Island. The DriX operated nearly 24/7 for 20 days. It collected data to characterize fish and plankton in Southern New England, including within five wind energy areas at various stages of development. This is a step toward using this innovative technology to study and sample marine life and habitats in places that are challenging for larger research vessels to access.

“Uncrewed systems have the ability to support various stock and ecosystem assessments through data acquisition, particularly in areas that have traditionally been or are increasingly becoming challenging to sample,” explained Conor McManus, Advanced Technology Program Lead for the science center. “We are learning more about how marine ecosystems are changing while improving the technology and operations to be able to use it more expansively in the future.”

The DriX is a submarine-shaped, 25-foot-long uncrewed surface vehicle. Unlike a sub, the DriX operates entirely on the surface. The vehicle is programmed to collect data along transect lines but can correct its course to avoid objects in the water. Similar to a car’s cruise control, it is monitored by trained operators who are remotely present and can take control when necessary. DriX is a flexible platform that can carry many sensors needed to collect oceanographic data. For this survey, DriX was outfitted with:

  • Seapix multibeam sonar (150 kHz)
  • Konsberg EK80 echosounder (38, 70, 120, 200 kHz)
  • Nortek Signature 500 kHz echosounder and acoustic doppler current profiler

These instruments collected data that will help scientists identify fish and plankton fields, as well as currents and other environmental information. For example, data collected by the Seapix can be used to estimate the volume of a school of fish.

DriX and other autonomous and semi-automous vehicles can complement ship-based surveys and improve the efficiency of collecting acoustic and biological data. The DriX could help fill data gaps by working in tandem with our long-term ecosystem surveys, such as the Bottom Trawl Survey. The science center’s surveys, including the Bottom Trawl, have been consistently collecting data on fisheries, ocean conditions, and habitat from the Gulf of Maine to North Carolina for more than 50 years.

During the first week, scientists launched and accompanied the DriX aboard the R/V Gloria Michelle, a 72-foot research vessel homeported in Woods Hole, Massachusetts. They calibrated the acoustic equipment and plankton sampling systems while collecting oceanographic data in the Revolution Wind Energy Area.

More than a quarter of staff gone at NOAA’s Northeast Fisheries Science Center

May 5, 2025 — The Northeast Fisheries Science Center (NEFSC)—a branch of the National Oceanic and Atmospheric Administration (NOAA) with an office in Woods Hole—has seen a 27 percent reduction in staff since President Donald Trump took office, according to current and former NOAA employees, who asked not to be named in this story for fear of retaliation.

In addition to the lab in Woods Hole, the NEFSC has four other offices—one each in Rhode Island, New Jersey, Connecticut and Maine. It is not yet clear how many of the departed staff worked in Woods Hole, which is described on the NOAA Fisheries website as the “focal point for the Northeast Fisheries Science Center’s operations, management and information needs.”

The 27 percent reduction in staff includes people who took early retirement or voluntary separations. It also includes individuals who were let go as “probationary” employees—new hires or employees who have moved into a new role.

NOAA declined to comment, citing a policy at the agency not to discuss internal personnel matters. This reduction in staff comes as part of the Trump administration’s efforts to reduce federal spending.

$2M Grant to Fishermen’s Alliance Means More Boats Gathering Ocean Data

December 5, 2024 — Strange things have been happening in recent years in the Gulf of Maine, the 36,000 square miles of relatively enclosed ocean stretching from Cape Cod to Nova Scotia. Low-oxygen zones have become annual occurrences, a large brown algae bloom in summer 2023 grew from Maine to northern Massachusetts, and looming over it all is the accelerating warming of surface waters. The Gulf of Maine is warming three times faster than the global average, according to the Maine Climate Council, which is faster than 99 percent of the world’s oceans.

Understanding these phenomena and their effects on fisheries is difficult, said Owen Nichols, Director of Marine Fisheries Research at the Center for Coastal Studies, because of the lack of data available on the ocean water below the surface — at the depths where most fish live.

There is one group of people, however, who regularly put equipment deep in the ocean: fishermen. And many of them are already working with scientists to gather data on the water.

But on Oct. 31, Gov. Healey’s administration announced a nearly $2 million grant to the Chatham-based Cape Cod Commercial Fishermen’s Alliance that will significantly expand fishing vessel-based measurements. The grant is from the quasi-public Mass. Technology Collaborative.

Since 2001, a Northeast Fisheries Science Center project has partnered with local fishermen to try to fix the lack of data about the depths. The project, called eMOLT (Environmental Monitoring on Lobster Traps and Large Trawlers), has so far installed sensors on about 100 fishermen’s gear to gather data on stratification of water temperature, dissolved oxygen levels, and other parameters.

2022 NOAA Northeast Sea Scallop Survey Results

June 28, 2022 — The NOAA Fisheries Integrated Sea Scallop and Habcam Research Survey is in the books for 2022. Scientists and crew completed their work aboard the University of Delaware’s R/V Hugh R. Sharp on June 13, 2022.

The Atlantic sea scallop population is surveyed every summer by NOAA Fisheries and partnering research groups. This year those partners are the Coonamessett Farm Foundation, the Virginia Institute of Marine Science and the University of Massachusetts-Dartmouth School of Marine Science and Technology. Each partner surveys an assigned area using similar methods and a standardized survey design. Here, we are reporting results for the survey areas allocated to the NOAA Fisheries-based effort, led by the Northeast Fisheries Science Center.

Resulting data are used for fishery stock assessments, fishery management, and biological studies. Sea scallops are one of the most valuable commercial fishery species in the nation.

Leg 1 of the survey was conducted May 14 to 23 off the Mid-Atlantic and southern Georges Bank. Researchers deployed the stereo camera and sensor system known as Habcam V4.

Leg 2 was conducted from May 25 to June 3, and Leg 3 operated from June 5 to June 13. On these legs, we deployed both Habcam V4 and a scallop dredge. The dredge is a standardized 8-foot wide New Bedford sea scallop dredge that collects sea scallops for biological analyses.

New England lobster, crab boats could begin using experimental ropeless gear with federal permits

June 6, 2022 — Federal fisheries officials are proposing a special permit to allow up to 100 New England lobster and crab boats to use experimental high-tech systems to retrieve their traps. That would mark a big expansion in the development of fishing systems that could help protect endangered North Atlantic right whales.

The technology uses remote-control systems to locate and trigger traps or buoy lines to the surface, reducing the use of vertical rope lines that can entangle the right whales.

Henry Milliken supervises a prototyping program for the so-called “ropeless” gear at the Northeast Marine Fisheries Science Center in Woods Hole.

‘Ropeless’ lobster gear could be put to test in area closed to protect right whales

June 2, 2022 — An application to test innovative fishing gear throughout New England could get some Maine lobstermen back into a nearly 1,000-mile swathe of offshore fishing grounds for the first time since the implementation of a seasonal closure last year.

The Northeast Fisheries Science Center, a research arm of the National Oceanic and Atmospheric Administration, is seeking a permit to work with fishermen to trial “ropeless” fishing gear in several parts of New England, including the 967-square mile closure area off the midcoast.

The lucrative fishing grounds were closed off last year for the first time as part of a slew of new regulations designed to protect the endangered right whale. From October through January — the heart of the offshore fishing season — lobstermen can only fish in the area with a permit and if they use ropeless technology, which is costly and unfamiliar.

But if the federal marine research program’s application is approved, a few fishermen may get to try loaned ropeless fishing gear during the next closure.

“This whole effort is to provide fishermen a tool so they can access those closed areas,” said Henry Milliken, a research fisheries biologist with the center.

NMFS to expand Northeast ropeless gear trials

June 1, 2022 — Up to 100 commercial lobster vessels would be allowed to test alternative gear without static vertical lines, under an exempted fishing permit application filed by the Northeast Fisheries Science Center.

Up to 30 of those boats would be allowed to fish using so-called ropeless gear in areas where conventional lobster gear with vertical line is restricted under the Atlantic Large Whale Take Reduction Plan, according to a notice issued May 31 by the National Marine Fisheries Service.

The permit application, to be published in the June 1 Federal Register, is subject to a public comment period through June 15. NMFS is looking to on-demand or pop-up buoy retrieval systems in the lobster fishery as a long-term solution to reducing whale entanglements in lobster gear, particularly for the highly endangered northern right whale.

Changing Oceanographic Conditions And Environmental Justice Concerns In The Northeast Shelf

April 6, 2022 — Two new reports show the Northeast continental shelf marine ecosystems are experiencing notable ocean warming and changes in oceanography. The reports include new indicators that evaluate environmental justice concerns.

The Northeast shelf extends from North Carolina to Maine and is one of the most productive marine ecosystems in the United States. The annual New England and Mid-Atlantic State of the Ecosystem reports capture the big picture of the biology, climate, physical, and social conditions of the marine ecosystem. The assessments inform fisheries management by showing how the ecosystem is connected and changing. This ecosystem change, in turn, affects the distribution and abundance of marine species from phytoplankton to whales.

“We develop these reports along with the regional fishery management councils to provide information on current social, economic, and environmental conditions and address priority questions on factors affecting their management objectives. Every year, the Mid-Atlantic Fishery Management Council uses these reports to update their ecosystem level risk assessment. This gives managers a quick overview of conditions that may affect fisheries,” said Sarah Gaichas, co-editor at the Northeast Fisheries Science Center.

North Atlantic right whale researchers spot 21 right whales south of Nantucket during winter field work

March 10, 2022 — North Atlantic right whale researchers recently spotted more than 20 right whales while exploring southern New England waters during winter field work.

For the very first time, the New England Aquarium scientists are surveying this region by boat as they try to better understand climate change impacts on this critically endangered species.

The researchers went out on the water for four days from mid-January to early March, looking for right whales about 70 miles south of Nantucket. The scientists spotted 17 individual right whales by boat, or about 5% of the population, which is estimated to be less than 350.

Aquarium scientists worked in tandem with the New England Aquarium aerial survey team, as well as with teams from the Center for Coastal Studies and the Northeast Fisheries Science Center, which helped navigate the boat to whale sightings. In total, the aquarium teams identified 21 unique right whales from either the air or the water.
