The role of the Arctic Ocean as a potential area of the anthropogenic CO2 sink in the global carbon budget is usually ignored , because most of the Arctic Ocean is covered by ice all year round. It is assumed that the "ice cap" restricts CO2 fluxes in the ocean-atmosphere system, although the degree of such a restriction remains thus far unknown. At the same time, the shelf seas that constitute one-third of the Arctic Ocean are ice-free during the summer and represent potential reservoirs for the excess atmospheric CO2, as they are characterized by high seasonal productivity and low water temperature. At the same time, anomalously high pCO2 values were discovered in the coastal zone of the Russian Arctic region. Our present knowledge of the CO2 exchange in the ocean-atmosphere system does not provide grounds to define unambiguously the areas of the Arctic Ocean that are responsible for the absorption and release of CO2. The purpose of this work is to assess waters of the East Siberian Sea as a potential source and/or sink for excess atmospheric CO2.
