Now let's take a look at the current from above. The tip of the ink line is flowing to the top left of the photo, that is, a 45 degree angle to the wind's direction. At greater depths, the current rotates to the right, and the ink line forms a spiral. The direction of the current changes with depth, but if you take the average of the whole, the amount of water flowing up- and downwind is the same, so on average there is no current either up or downwind. The average direction of the current is at 90 degrees to the right of the wind's direction. This net current is called Ekman transport and flows sideways.
