A year-round acoustic study of marine mammals in the northern Bering Sea is providing scientists with a valuable snapshot of an Arctic world already under drastic pressure from climate change, according to WCS (Wildlife Conservation Society), Columbia University, Southall Environmental Associates, and the University of Washington.
Authors of the new study in the journal Marine Mammal Science conducted a 4-year acoustic monitoring project to determine how seasons, sea surface temperature, and sea ice influence the presence, distribution, and movements of five species of endemic Arctic marine mammals. It is the first study to conduct year-round acoustic monitoring for marine mammals off St. Lawrence Island in the Bering Sea.
“The data gathered during the study will serve as an important baseline for future monitoring of the effects of climate change, subsequent sea ice changes, and expected increases in shipping on the distribution of the region’s marine mammals,” said Emily Chou, WCS scientist and lead author of the study.
