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.
At a depth of about 100 to 150 m (330 to 500 ft), the Ekman spiral has gone through less than half a turn. Yet water moves so slowly (about 4% of the surface current) in a direction opposite that of the wind that this depth is considered to be the lower limit of the wind's influence on ocean movement.
