The main water transformations in the Arctic Mediterranean take place in the boundary current of Atlantic Water, which crosses the Greenland–Scotland ridge from the North Atlantic into the eastern Norwegian Sea. It enters and flows around the Arctic Ocean before it exits the Arctic Mediterranean as the East Greenland Current, primarily through Denmark Strait. On route, it experiences numerous branchings and mergings. By examining how the properties of this "circumpolar" boundary current evolve, it is possible to identify and describe the processes causing the water mass transformations in the Arctic Mediterranean. It is also possible to follow the Arctic Ocean deep waters as they spread into the Nordic Seas and eventually provide 40% of the overflow water supplying the North Atlantic Deep Water.
