    Upwelling
    The physical process in near-shore ocean systems of rising of nutrients and colder bottom waters to the surface because of constant wind patterns along the shoreline. Upwelling areas are highly productive of plankton and fish.

    upwelling
    (from the article `marine ecosystem`) The most productive waters of the world are in regions of upwelling. Upwelling in coastal waters brings nutrients toward the surface. Phytoplankton ... Upwelling is a seasonal phenomenon in the Indian Ocean because of the monsoon regime. During the southwest mon...

    UPWELLING
    The process by which water rises from a lower to a higher depth, usually as a result of divergence and offshore currents. It influences climate by bringing colder, more nutrient-rich water to the surface. A vital factor of the El Niño event.

    Upwelling
    In ocean dynamics, the upward motion of sub-surface water toward the surface of the ocean. This is often a source of cold, nutrient-rich water. Strong upwelling occurs along the equator where easterly winds are present. Upwelling also can occur along coastlines, and is important to fisheries and bir...

    upwelling
    area in the ocean where nutrient-rich bottom water surfaces. It produces blooms of phytoplankton and with it dense populations of fast-reproducing fishes, preyed upon by carnivores, sea mammals and sea birds. The productivity of upwellings compares to that of estuaries, and is typically ten times hi...

18. 
    Upwelling
    the process by which water, usually cold and nutrient-rich, rises from a deeper to a shallower depth. This is often a result of offshore surface water flow, particularly when persistent wind blows parallel to a coastland and the resultant Ekman transport moves surface water away from the coast.
