ARCTIC FLOW

In ARCTIC-FLOW we plan to generate new 16-year temporal series of satellite-derived freshwater and density flux products for Arctic and sub-Arctic regions by using in a synergistic way satellite estimates of Sea Surface Temperature, Sea Surface Currents and Sea Surface Salinity. The new satellite-derived assessment of freshwater and density fluxes will be used to study changes in water column density on different time scales, with a focus on the upper ocean stratification and water mass transformation in the subpolar North Atlantic and the Nordic Seas. Changes in upper ocean density caused by the advection of cold and fresh Arctic water from the north, warm and salty Atlantic water from the south have a profound effect on convection in the Nordic Seas and the subpolar North Atlantic.
