Marine Mammal Passive Acoustic Recorders

Marine Mammal Passive Acoustic Recorders

Location: Bering and Chukchi Seas

Timing: August - September

Funding: NOAA, Bureau of Ocean Energy Management (BOEM), North Pacific Research Board (NPRB)

Project: This continues a decade of passive acoustic monitoring of marine mammals in the Alaskan Arctic and Bering Sea. Moorings supporting passive acoustic recorders have been distributed throughout the main migratory pathways and in wintering and summering grounds of many Arctic and subarctic marine mammals. Many moorings have been co-located with long-term moorings that are collecting information on oceanography and noise levels. Collaborators include NOAA Pacific Marine Environmental Lab, NOAA Resource Assessment and Conservation Engineering, Cornell University, and Department of Fisheries and Oceans Canada.
