The northern Bering and Chukchi Seas. The colors illustrate gridded benthic macroinfaunal dry weight carbon biomass per square meter on a logarithmic scale, by averaging scattered benthic observations with gray dots that represent station locations. Dash-line bounding boxes indicate geographic domains of 4 benthic biological hotpots from south to north as defined in Grebmeier et al. [2015]: St. Lawrence Island Polynya (SLIP), Chirikov Basin (Chirikov), Southeast Chukchi Sea (SECS), and Northeast Chukchi Sea (NECS).
