Autonomous Real-time Marine Mammal Detections

Woods Hole Oceanographic Institution


Cox Ledge, Winter 2021-2022


Study objectives

A Slocum G3 glider was deployed near Cox Ledge just south of Massachusetts and Rhode Island to conduct surveys for tagged fish and baleen whales, including the seriously endangered North Atlantic right whale. This is a BOEM funded study (Brian Hooker, BOEM. Award #M19PG00015) aimed at 'Mapping the distribution and habitat use of soniferous fish, with a focus on Atlantic cod spawning aggregations, on Cox Ledge.'

Principal Investigators: Sofie Van Parijs & Tim Rowell (NOAA Northeast Fisheries Science Center), Gregory DeCelles, Micah Dean & Bill Hoffman (MASS DMF), Christopher McGuire (TNC), Steve Cadrin, (UMASS SMAST), Susan Tuxbury (NOAA GARFO), Doug Zemeckis (Rutgers University) and Mark Baumgartner (WHOI)

Analysts: Julianne Wilder
