Ekman transport is a concept in oceanography that refers to the net movement of water induced by wind stress over the surface of the ocean. When wind blows across the surface of the sea, it creates friction between the air and the water, causing the surface water to move in the direction of the wind. However, due to the Coriolis effect—resulting from the Earth's rotation—the surface water is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
