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.
The key factor for wind driven upwelling is the direction of the Ekman layer transport relative to the coast. Optimum upwelling conditions are obtained when the Ekman transport divergence is maximized, which occurs when the Ekman transport is directed offshore and normal to the coastline.
