The joint research program will take place on the eastern Bering Sea shelf between the Aleutian Islands and St. Lawrence Island.
This region supplies food resources for commercial fishing industry, as well as for more than 30 Alaska Native communities, millions of seabirds, and tens of thousands of marine mammals.
This production is fueled by nutrients annually replenished from slope and oceanic waters across the very broad (>500 km) continental shelf. Seasonal sea ice extent currently divides the Bering Sea eastern shelf into two biogeographic provinces.
Here, south of the average-annual maximum sea ice extent, most primary production remains within the pelagic ecosystem and pollock is the dominant consumer.
Here, tight coupling between pelagic primary production and the benthos benefits benthic foragers such as gray whales, walrus and some seabird species.
The average southern edge of the maximum ice extent currently lies north of the Pribilof Islands. The boundary between these provinces is not stationary, and is expected to move northward as the region becomes warmer.
