Using a Geographical Information System Approach to Assess Sea Ice Impacts on a Productive Benthic System in the Northern Bering Sea
Physical, hydrochemical, and biological data were collected during three research cruises from winter through spring in the northern Bering Sea. In addition, seasonal ice cover data were used to evaluate the relationship between ice and specific biological processes. Ice-water-biotic interactions we...
