Autonomous Real-time Marine Mammal Detections
Woods Hole Oceanographic Institution
Chukchi Sea, Arctic, Summer 2016
Study objectives
A Slocum G2 glider was deployed in the Chukchi Sea off the northwest coast of Alaska on July 10, 2016 to study the occurrence of several species of marine mammals, including fin, bowhead, and beluga whales, as well as bearded seals and walrus. This project is designed to examine relationships between marine mammal distribution and oceanographic conditions monitored by the glider. Results shown on this page have been reviewed by an experienced analyst (Kate Stafford) and represent locations and times where the near real-time passive acoustic detection data provide evidence of species occurrence.
Principal Investigators: Peter Winsor (University of Alaska Fairbanks), Kate Stafford (University of Washington), and Mark Baumgartner (WHOI).

The Slocum glider was prepared and deployed by Brita Irving and Hank Statscewich (UAF). Deployment was made possible by Rebecca Woodgate (UW), chief scientist of the deployment cruise on the R/V Norseman II. At sea assistance was provided by the captain and crew of the R/V Norseman II. Critical engineering support was provided by Keenan Ball, Jim Partan, and Tom Hurst (WHOI). Support for the development of the Arctic marine mammal call library was provided by Alaska Ocean Observing System and support for the preparation of the DMON/LFDCS and preparation and operation of the glider for this study was provided by the North Pacific Research Board. Support for the development and testing of the DMON/LFDCS was provided by the Office of Naval Research, and additional support for integration and testing was provided by 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).
