Autonomous Real-time Marine Mammal Detections

Woods Hole Oceanographic Institution


Laurentian Channel, Gulf of St. Lawrence, Canada, August 2020


Study objectives

A Teledyne Webb Research Slocum G3 glider equipped with passive acoustic listening device (DMON/LFDCS) was deployed in the Laurentian Channel region of the Gulf of St. Lawrence (GoSL) for a three month mission. The purpose of this mission is to monitor for North Atlantic right whales and use right whale acoustic detections to trigger dynamic management in Dynamic Zone C of the Laurentian Channel Traffic Separation Scheme.

Principal Investigators: Kim Davies (University of New Brunswick)

Analysts: Kim Davies (University of New Brunswick) and Delphine Durette-Morin (Dalhousie University)

Acknowledgements

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, MEOPAR 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).
