upwelling
意味: The rising of cold, nutrient-rich water from the deep ocean towards the surface, typically driven by winds that push surface water away from a coastline or along the equator.
Upwelling zones are among the most biologically productive areas in the ocean. The nutrients brought to the sunlit surface fuel phytoplankton growth, which in turn supports fish stocks and seabird colonies. Major upwelling regions include the coasts of Peru, California, and West Africa. In the UK context, localised upwelling occurs around headlands and in the Celtic Sea. El Niño events suppress upwelling off South America with devastating consequences for fisheries. It collocates with 'coastal,' 'nutrient,' 'productivity,' 'wind-driven,' and 'ocean.'
