We investigate the response of the Nordic seas-Arctic Ocean system to surface freshwater flux anomalies that we regard as typical for long-term atmospheric variability. We employ response experiments with a coupled sea ice-ocean model where we introduce a surface freshwater flux anomaly (A) over the Norwegian Sea and (B) in the Laptev Sea. Case A offers an explanation for the intermediate depth salinity changes observed in the Amundsen Basin. The signal observed there belongs to an original perturbation that, according to the model, occurred around a decade earlier. Salinity fluctuations in the Laptev Sea could play a role in changes in the near surface salinity in the Amundsen Basin.
