Autonomous Real-time Marine Mammal Detections

Woods Hole Oceanographic Institution


Shediac Valley, Gulf of St. Lawrence, Canada, June 2018


Study objectives

A Teledyne Webb Research Slocum G3 glider equipped with passive acoustic listening device (DMON/LFDCS) was deployed in the Shediac Valley region of the Gulf of St. Lawrence (GoSL) for 3-4 months. This is one of three gliders that will be launched to survey three different areas of the GoSL (Shediac Valley, Orpheline Trough and American Bank-Laurentian Channel). 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.

Principal Investigators: Kim Davies, Chris Taggart, Hansen Johnson (Dalhousie University) and Mark Baumgartner (WHOI)

Analysts: Kim Davies, Delphine Durette-Morin and Hansen Johnson (Dalhousie University)

The Dalhousie glider was expertly prepared by Adam Comeau, Jude van der Meer, Tyler Byrne, and Richard Davis (Dalhousie University). 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), 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: meopar.ca/research/project/whale-whales-habitat-and-listening-experiment. 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).
