Autonomous Real-time Marine Mammal Detections

Woods Hole Oceanographic Institution


Cox Ledge, Winter 2020-2021


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: Genevieve Davis (NOAA NEFSC)

The Slocum glider was expertly prepared and deployed by Ben Hodges (WHOI). Engineering support for the DMON2 instrument deployed on this glider was provided by Jim Partan, Dennis Giaya, Kayleah Griffen, Keenan Ball, Steve Faluotico and Tom Hurst (WHOI). Support for the deployment and operation of the glider was provided by NOAA Northeast Fisheries Science Center. Support for the development and testing of the DMON/LFDCS was provided by the Office of Naval Research, and additional support for integration and testing was provided by the NOAA National Marine Fisheries Service Advanced Sampling Technologies Working Group in collaboration with the Northeast Fisheries Science Center's Passive Acoustics Research Group (leader: Sofie Van Parijs).
