Meet the Autonomous Underwater Robot Expanding Our Ability to Survey the Seafloor

August 31, 2026 — For the past 3 years, our Habitat Camera (HabCam) Survey has had self-propelled underwater helpers. From June 30 to July 6 of this year, two Tethys-class long-range autonomous underwater vehicles, or LRAUVs, surveyed more than 200 nautical miles of pre-programmed track lines in the Mid-Atlantic. Together, they captured more than 68,000 images of the seafloor, collecting critical data used in fisheries stock assessments.

LRAUVs provide an alternative way to survey areas of the ocean where traditional research vessels cannot go because of offshore development. The data they collect complements our vessel-based HabCam Survey, which collects millions of seafloor images each year to understand Atlantic sea scallop populations.

Technology Strengthens the Sea Scallop Assessment

Our scientists identified sea scallops, fish, crabs, snake eels, squid, skates, and more in the seafloor images taken by LRAUVs this year. They will present these data, along with HabCam Survey data, to the New England Fishery Management Council at the end of August. The Council’s Scallop Plan Development Team will incorporate the data into the Atlantic sea scallop assessment. Ultimately, the data help generate more accurate estimates of sea scallop abundance and distribution to inform management decisions.

Advanced Technology Specialist Cameron Fairclough notes that this technology expands where and when we can collect data. “This autonomous underwater vehicle can image the seafloor and you can control it from your phone while it’s out in the middle of the ocean,” he explained.

NEFMC Adopts Scallop Amendment 21 with Measures for NGOM, LAGC IFQ Fishery

October 8, 2020 — The following was released by the New England Fishery Management Council:

The New England Fishery Management Council has signed off on Amendment 21 to the Atlantic Sea Scallop Fishery Management Plan, which includes new measures to: (1) better manage total scallop removals from the Northern Gulf of Maine (NGOM) Management Area by all components of the fishery; and (2) expand NGOM Allocations Under Amendment 21: Once the NGOM allocation is determined, deductions are made off-the-top to support monitoring and research. Of what’s left, the first 800,000 pounds goes to the NGOM set-aside. Anything above 800,000 is shared as shown in the flowchart above. flexibility in the Limited Access General Category (LAGC) Individual Fishing Quota (IFQ) fishery. The amendment still needs to be approved by the National Marine Fisheries Service (NMFS/NOAA Fisheries) before being implemented.

Northern Gulf of Maine (NGOM)

Under Amendment 21, the Council will begin accounting for scallop biomass in the NGOM area in the same flowchart it uses to calculate the overfishing limit (OFL) and acceptable biological catch (ABC) for the rest of the resource. The NGOM annual catch limit also will be set consistent with how the rest of the fishery is managed, bringing the area more in line with the Georges Bank and Mid-Atlantic scallop fishery

UMass professor nets $300K for scallop research

June 1, 2018 — PROVIDENCE, R.I. — University of Massachusetts Dartmouth professor Kevin Stokesbury was awarded $302,091 in grants from the National Oceanic and Atmospheric Administration as part of its 2018-2019 Sea Scallop Research Set-Aside program, the university announced Thursday.

Stokesbury, a professor of fisheries oceanography at the School for Marine Science & Technology, will use the funds to examine scallop populations around New England, including near the Nantucket Lightship shoals, the deep-water passage between Nantucket and Georges Bank, and select portions of the Northern Gulf of Maine. The three projects were awarded $95,721, $84,065 and $122,305, respectively.
