Second, local and small-scale openings in the ice cover (polynyas) provide the necessary brine release for dense bottom waters. The polynyas open frequently near Franz Josef Land and Novaya Zemlya due to oV-shore winds. Tidal currents, however, may also play a role in opening the closed ice sheet. T...

Summary: | Second, local and small-scale openings in the ice cover (polynyas) provide the necessary brine release for dense bottom waters. The polynyas open frequently near Franz Josef Land and Novaya Zemlya due to oV-shore winds. Tidal currents, however, may also play a role in opening the closed ice sheet. Tracer studies reveal that most of the bottom water leaves the Barents Sea through the Svyataya Anna Trough towards the Arctic Ocean. Outflow rates of the deep water as well as the temporal and spatial evolution of stratification and ice cover are presented. |
