upwelling


upwelling
an upward movement of cold, nutrient-rich water from the ocean depths, often associated with great production of fish and fisheries. For fisheries, the most important types are wind-induced coastal upwelling where the upward movement is a consequence of wind stress (along shore) and Eckman transport (offshore)
the movement of nutrient rich waters and colder from the bottom of the ocean to the surface; often results in areas rich in fishes
