Autonomous Real-time Marine Mammal Detections

Woods Hole Oceanographic Institution


Chukchi Sea, Arctic, Summer 2022


Study objectives

A Slocum G2 glider was deployed in the Chukchi Sea off the northwest coast of Alaska on July 30, 2022 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 (Oregon State University), Seth Danielson (University of Alaska Fairbanks), and Mark Baumgartner (WHOI)

The Slocum glider was expertly prepared by Hank Statscewich (UAF). Deployment was made possible by Bob Pickart (WHOI), chief scientist of the deployment cruise on the M/V Norseman II. At sea assistance was provided by the captain and crew of the M/V Norseman II. Support for the development of the Arctic marine mammal call library as well as the preparation and operation of the glider in 2022 was provided by Alaska Ocean Observing System. The glider was procured in 2016 with support from the North Pacific Research Board.
