Autonomous Real-time Marine Mammal Detections

Woods Hole Oceanographic Institution

GoSL Dynamic Shipping Zones, Canada, September 2021

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 4-5 month mission. The primary objectives of this mission are to monitor the presence of North Atlantic right whales and use right whale acoustic detections to trigger dynamic management in Dynamic Shipping Zones C and E of the Laurentian Channel Traffic Separation Scheme.
