Autonomous Real-time Marine Mammal Detections

Woods Hole Oceanographic Institution


Gulf of St. Lawrence, Canada, October 2017


Study objectives

A Teledyne Webb Research Slocum glider equipped with passive acoustic listening device (DMON/LFDCS) was deployed in the southern Gulf of St. Lawrence to explore the Orphaline Channel region as a potential habitat of the endangered North Atlantic right whale, as well as other baleen whales. This mission also provides reconnaissance for survey vessels and planes searching for right whales in the region.

Principal Investigators: Kim Davies, Chris Taggart, Hansen Johnson, Richard Davis (Dalhousie University), Moira Brown (New England Aquarium/Canadian Whale Institute), and Mark Baumgartner (WHOI)

Analyst: Kim Davies and Hansen Johnson (Dalhousie University)

Acknowledgements

The Dalhousie glider was expertly prepared by Adam Comeau, Jude van der Meer, Sue L'Orsa, 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) and the Ocean Tracking Network (OTN). 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).
