Mapping of the air-sea CO 2 flux in the Arctic Ocean and its adjacent seas: Basin-wide distribution and seasonal to interannual variability
We produced 204 monthly maps of the air–sea CO2 flux in the Arctic north of 60°N, including the Arctic Ocean and its adjacent seas, from January 1997 to December 2013 by using a self-organizing map technique. The partial pressure of CO2 (pCO2) in surface water data were obtained by shipboard underwa...
