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.
In these wind driven currents, the Ekman spiral effect results in the currents flowing at an angle to the driving winds. In addition, the areas of surface ocean currents move somewhat with the seasons; this is most notable in equatorial currents.
