The sunlight goes some way towards heating the Arctic, but heat also comes from the south with ocean currents and airstreams. One branch of the Gulf Stream, called the North Atlantic Current, flows along the coast of Norway and continues all the way to the Arctic Ocean. There it shifts its name to the West Spitsbergen Current, and almost 60 % of the water entering the Arctic Ocean comes with this.
The main currents in the Arctic. The Arctic surface waters extend to a depth of about 46 meters, and are far less salty than the waters below. The deeper Arctic waters near the ocean floor are very salty and therefore quite dense, and so do not flow readily. Generally, the surface waters of the Arctic Ocean circulate in a large clockwise rotational pattern moving from east to west around the polar ice cap.
