ABSTRACT
The Arctic Ocean freshwater balance over the period 1948-2001 is examined using results from a hindcast simulation with an ocean-sea ice model of the Atlantic and Arctic Oceans. Atmospheric forcing is taken from the NCEP-NCAR reanalysis and different terrestrial freshwater sources as well as the Bering Strait throughflow are specified as constant seasonal cycles. The long-term variability of the Arctic Ocean liquid freshwater content is determined by the variability of lateral exchanges with the subpolar seas. Surface freshwater flux variability is dominated by the thermodynamic growth of sea ice. This component of the freshwater balance has larger variability at interannual ...
