Autonomous Real-time Marine Mammal Detections

Woods Hole Oceanographic Institution


Honguedo Strait, Gulf of St. Lawrence, Canada, September 2019


Study objectives

A Teledyne Webb Research Slocum G3 glider equipped with passive acoustic listening device (DMON/LFDCS) was deployed in the Honguedo Strait region of the Gulf of St. Lawrence (GoSL) for two months. The purposes of this survey are to (1) monitor the Honguedo Strait shipping lanes and surrounding waters for North Atlantic right whales and other baleen whale species, and (2) study the application of gliders in this region as a tool to inform dynamic management to reduce ship strike risk.

The G3 glider was expertly prepared by Teledyne Webb Research and the Coastal Environmental Observation Technology and Research (CEOTR) group (ceotr.ocean.dal.ca). Financial support for the deployment and operation of the glider was provided Transport Canada's Innovation Centre. Additional logistical support for the mission was provided by Woods Hole Oceanographic Institution, University of New Brunswick, Teledyne Webb Research, Dalhousie University, Ocean Tracking Network, Shipping Federation of Canada, JASCO Applied Sciences, and the Ocean Frontiers Institute. 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).
