Upwelling is an oceanographic feature that is very important to the ocean ecosystem. It brings high nutrient water to the surface and the impact is noteworthy to the ocean productivity. This nutrient-rich water will encourage a phytoplankton bloom that is ultimate base for large animal population in the food chains, including fish, mammals and sea birds. Although this coastal upwelling regions covers relatively small areas of the ocean surface, they contribute roughly 50 percent of the world’s fisheries landings.
