Sea ice drift and ocean currents are to a large degree driven by the wind. Sea ice thickness, sea ice concentration and sea ice roughness influence the momentum flux from the atmosphere to the ocean (Castellani et al., 2015 and Itkin et al., 2014) The Beaufort Gyre, the Transpolar Drift and finally the export of sea ice and relatively fresh water through Fram Strait depend on these sea ice properties. A feedback loop connects oceanic heat transport, winds and sea ice transport in the Greenland Sea (Kovacs et al.2020). We expect similar feedback loops to exist in other regions of the Arctic Ocean and the Nordic Seas.
