2026 Spring Habitat Camera Survey Completed in Northeast

October 15, 2026 — Our Habitat Camera (HabCam) Survey uses a towed camera sled system to collect images of the seafloor. We analyze the images to estimate the abundance and size composition of Atlantic sea scallops. The sea scallop abundance, size composition, and distribution data are used annually as part of the sea scallop stock assessment and management processes. The survey is one of the primary fishery-independent surveys used in the sea scallop stock assessment model.

We also annotate the images for other seafloor features and animals such as crabs and finfish. We conduct the survey in the Mid-Atlantic Bight and Georges Bank. Because the camera sled is towed behind the vessel, the survey can sample more seafloor than traditional sea scallop survey methods.

Dates and Legs

The 2026 HabCam Survey began on May 11, 2026 and completed operations on May 29, 2026. We conducted the Spring survey aboard the NOAA Ship Henry B. Bigelow and it occurred in two legs:

  • Leg 1: May 11–19 in Mid-Atlantic Bight
  • Leg 2: May 20–29 in Georges Bank

Survey Location

This survey monitored the Mid-Atlantic and Georges Bank Atlantic Sea Scallop management areas:

In the Mid-Atlantic, the survey monitored:

  • Delmarva
  • Elephant Trunk
  • Hudson Canyon South
  • A mid-line through New York Bight and Long Island
  • Mid-Atlantic Bight Nearshore areas

In Georges Bank, the survey monitored:

  • Nantucket Lightship-West
  • CL1 (Groundfish Closed Area 1)
  • Northern Flank
  • CL2-North (Groundfish Closed Area 2)
  • Great South Channel

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.
