This forces ocean water westward, where it piles up and sea level rises. As the model shows, this produces in the western portion of the ocean basin. At the same time, the Ekman transport causes a lowering of sea level in the eastern portion of the basin, where ocean water moves in the opposite vertical direction.

Upwelling

Explanation:

Upwelling is a phenomenon in oceanography in which wind causes cold water from the deep to move to the surface. When such occurs water rich in nutrient are pushed to the surface by the force of wind, such water are regarded as the world's most productive water because they aid production in phytoplankton and leads to the increase in population of grazing zooplankton on the surface water. It also helps in the movement of marine animals.
