Autonomous Real-time Marine Mammal Detections
Woods Hole Oceanographic Institution
Chukchi Sea, Arctic, Summer 2018
Study objectives
A Slocum G2 glider was deployed in the Chukchi Sea off the northwest coast of Alaska on June 13, 2018 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: Kate Stafford (University of Washington), Peter Winsor (University of Alaska Fairbanks), and Mark Baumgartner (WHOI).

The Slocum glider was prepared and deployed by Brita Irving and Hank Statscewich (UAF). Deployment was made possible by Seth Danielson (UAF), chief scientist of the deployment cruise on the R/V Sikuliaq. At sea assistance was provided by the captain and crew of the R/V Sikuliaq. Support for the development of the Arctic marine mammal call library as well as the preparation and operation of the glider in 2018 was provided by Alaska Ocean Observing System. The glider was procured in 2016 with support from 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).
