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.
In this way, the ocean currents help regulate Earth's climate by facilitating the transfer of heat from warm tropical areas to colder areas near the poles. The water of the ocean surface moves in a regular pattern called surface ocean currents. On this map, warm currents are shown in red and cold currents are shown in blue.

Where these winds blow in the same direction for long periods of time, large currents develop and transport vast amounts of water over long distances.
