Despite representing only the 1% of the total ocean’s water, the discharge by Arctic rivers accounts for about the 11% of the freshwater flow into the ocean. This huge volume of low density freshwater restricts the mixing between surface and deep ocean layers, because of the induced strong stratification. The accumulation of low salinity water on top layers helps the formation of sea ice, increasing the Earth’s albedo. Remote sensing is actively contributing to complete the scarce measurements available in such extreme medium as the Arctic
