June 24, 2019 — The following was released by NOAA Fisheries:
The 2019 Northeast sea scallop survey got underway May 15 aboard the R/V Hugh R. Sharp, first covering stations in the Mid-Atlantic and then on Georges Bank. Operations concluded on June 14.
This survey occurs annually. It uses both a dredge to collect physical samples of sea life and their habitat, and a towed vehicle known as the HabCam. The HabCam is fitted with a number of sampling instruments, including cameras that photograph the ocean bottom. This dual sampling method enriches data available to researchers and helps ensure that information can be collected even if one of the systems fails during survey operations.

Most of the dredge operations occurred on Georges Bank. Planned dredge stations were completed throughout the Georges Bank area, and additional stations were added in the Great South Channel. Only two dredge stations were planned for the Mid-Atlantic area. These were completed.
HabCam coverage in the Mid-Atlantic was the most comprehensive achieved by the Center survey to date.
On Georges Bank, only the Southern Flank tracks and a small part of the northern Great South Channel were covered—about 30 percent of planned HabCam tracks for Georges Bank. HabCam tracks planned for the Northeast Edge and most of Great South Channel were not completed owing to operational issues with the HabCam vehicle and two days of unworkable weather.
“The sea scallop fishery is among the most valuable in the region, and people who rely on it also rely on us to provide the best possible data,” said Jon Hare, director of NOAA Fisheries’ Northeast Fisheries Science Center. “We were able to conduct additional dredge samples in the areas of Georges Bank that HabCam did not cover, and the team on the vessel did an excellent job adapting to the situation.”
