Autonomous Real-time Marine Mammal Detections

Woods Hole Oceanographic Institution


Cabot Strait, Canada, July 2021


Study objectives

A Teledyne Webb Research Slocum G3 glider equipped with passive acoustic listening device (DMON/LFDCS) was deployed in the Cabot Strait region of the Gulf of St. Lawrence (GoSL) for a 4-5 month mission. The primary objective of this mission is to research the distribution of North Atlantic right whales and other baleen whales in the Cabot Strait region to facilitate regional management of ship traffic.

Principal Investigators: Kim Davies (University of New Brunswick)
