Autonomous Real-time Marine Mammal Detections
Woods Hole Oceanographic Institution
Orpheline Trough, Gulf of St. Lawrence, Canada, August 2019
Study objectives
A Teledyne Webb Research Slocum G2 glider equipped with passive acoustic listening device (DMON/LFDCS) was deployed in the Orpheline Trough region of the Gulf of St. Lawrence (GoSL) for several months. This is one of two gliders that will be launched to survey different areas of the GoSL (Shediac Valley and Orpheline Trough). The purposes of these surveys are to (1) monitor and study the habitat of the endangered North Atlantic right whale, as well as four other species of baleen whales, (2) support dynamic and seasonal management measures implemented to protect right whales from fishing gear entanglement and ship strike, and (3) provide reconnaissance for survey vessels and planes searching for right whales in the region.

The Dalhousie glider was expertly prepared by the Coastal Environmental Observation Technology and Research (CEOTR) group (ceotr.ocean.dal.ca). Support for the deployment and operation of the gliders was provided by the Marine Environmental Observation Prediction and Response Network (MEOPAR) Whales, Habitat and Listening Experiment (WHaLE), the Ocean Tracking Network (OTN), National Science and Engineering Council of Canada (NSERC), Fisheries and Oceans Canada (DFO), the World Wildlife Federation (WWF), and Canadian Steamship Lines (CSL). MEOPAR-WHaLE is supported by 20 collaborating organizations, listed here. Support for the development, integration, and testing of the glider DMON/LFDCS was provided by the U.S. Office of Naval Research and 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).
