Inflow to the Arctic

Areas of inflow for the Arctic Ocean

Ocean currents in the Arctic Ocean are not only influenced by wind direction, but also by the inflow from the rivers that discharge into it. Water enters the Arctic Ocean from many sources, but the Mackenzie River in Canada and the Ob, Yenisey and Lena Rivers in Siberia are dominant. The North Atlantic Current provides about 60% of the inflow to the Arctic Ocean bringing warmer water from the Atlantic Ocean. Some water also moves into the Arctic Ocean from the Bering Sea and the Pacific Ocean, by way of the Bering Strait.
