One of his observations was that the ice was not moving in the same direction as the wind. It was moving consistently to the right of the wind direction. This phenomenon would later become known as Ekman transport. As wind blows across the ocean, it moves water because of friction at the ocean surface.
Downwelling is the opposite of upwelling-surface waters pushing down into deeper areas of the ocean. This happens when winds cause Ekman transport to push water toward a coast and then deeper in the ocean.Last modified September 18, 2008 by Lisa Gardiner.pwelling often happens where wind blows along a coastline. The wind causes the water at the ocean surface to move perpendicular to it, away from the coast, because of a process called Ekman transport.
