Autonomous Real-time Marine Mammal Detections

Woods Hole Oceanographic Institution


Gulf of Maine 2015


Study objectives

A Liquid Robotics wave glider was deployed in the Gulf of Maine to conduct near real-time passive acoustic surveys for baleen whales over the course of 1.5 years. Visual surveys will be conducted in proximity to the glider to validate the accuracy of the passive acoustic detections obtained by the DMON/LFDCS carried by the wave glider. These visual surveys will be conducted in the Great South Channel using shipboard observations, near Mount Desert Rock using land-based observations, and throughout the Gulf of Maine using observations from the NOAA Northeast Fisheries Science Center aerial survey.

Principal Investigators: Cara Hotchkin (NAVFAC Atlantic), Sofie Van Parijs (NEFSC), Peter Corkeron (NEFSC), and Mark Baumgartner (WHOI).

The wave glider was deployed by Hansen Johnson (Dalhousie University and WHOI). Critical engineering support was provided by Keenan Ball, Jim Partan, Tom Hurst, and Leo-Paul Pelletier (WHOI). Support for the deployment and operation of the wave glider is provided by the Department of Defense's Environmental Security Technology Certification Program (ESTCP) and the Navy's Living Marine Resources Program. The DMON instrument was developed by Mark Johnson and Tom Hurst at WHOI. Mark Johnson was responsible for developing the application programming interface (API) for the DMON, and coded the initial DMON implementation of the pitch tracking algorithm described in Baumgartner and Mussoline (2011). Support for the development and testing of the DMON/LFDCS was provided by the Office of Naval Research's Marine Mammals and Biology Program , and additional support for integration and testing of the DMON/LFDCS with the wave glider was provided by the WHOI Marine Mammal Center.
