Abstract
During the multidisciplinary "NEW92' cruise of the Polar Sea to the recurrent Northeast Water (NEW) Polynya (77-81°N, 6-17°W; July-August 1992), total dissolved inorganic carbon and total alkalinity in the water column were measured. Biological processes depleted the total inorganic carbon of summer surface waters by up to 2 mol C m-2 or about 3%. On a regional basis this depletion correlated with depth-integrated values of chlorophyll a,particulate organic carbon, and the inorganic nitrogen deficit. These measurements and observations allowed formulation of a new hypothesis whereby sesonally ice-covered regions like the N EW Polynya promote a unique biologically and physically mediated "rectification' of the typical (ice free, low latitude) seasonal cycle of air-sea CO2 flux. -Authors
