Integrating Passive Acoustic Monitoring in long-term oceanographic observations of the Bering Strait
This project aims to establish a base program for year-round acoustic monitoring of marine mammals in Bering Strait. Instrumentation will be added onto an existing high resolution physical and biological mooring program (National Science Foundation-Arctic Observing Network (AON) and Russian American...

This project aims to establish a base program for year-round acoustic monitoring of marine mammals in Bering Strait. Instrumentation will be added onto an existing high resolution physical and biological mooring program (National Science Foundation-Arctic Observing Network (AON) and Russian American Long-term Census of the Arctic), also supported by annual survey data. The combination of these data sets will provide urgently required, base-line information on how species presence varies seasonally with changes in sea ice, currents, ocean water temperatures and freshwater flow. Building on opportunistic proof-of-concept deployments in the strait in the last 2 years, the proposed effort will also provide critical, consistent data on interannual variability. The research project will test cutting edge scientific hypotheses such as: how do oceanographic conditions dictate the residency of different marine mammal species? Are temperate species invading the Arctic? What is the correlation between ice cover and marine mammal sound production? The Bering Strait is the only oceanic connection between the Pacific and the Arctic oceans.
