1. Upwelling

   Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water from deep water towards the ocean surface. It replaces the warmer and usually nutrient-depleted surface water. The nutrient-rich upwelled water stimulates the growth and reproduction of primary producers such as phytoplankton. The biomass of phytoplankton and the presence of cool water in those regions allow upwelling zones to be identified by cool sea surface temperatures (SST) and high concentrations of chlorophyll-a.The increased availability of nutrients in upwelling regions results in high levels of primary production and thus fishery production. Approximately 25% of the total global marine fish catches come from five upwellings, which occupy only 5% of the total ocean area. Upwellings that are driven by coastal currents or diverging open ocean have the greatest impact on nutrient-enriched waters and global fishery yields.

Examples of upwelling in a Sentence

1. Professor Levin:

   The upwelling we detected is like a hot-air balloon, and we infer that something is rising up through the deeper part of our planet under New England.

2. Oceanographer Autun Purser:

   There is generally a low reign of food, as it is in the middle of the Pacific Gyre, a low productivity area with little upwelling nutrient rich waters, so though there will be seafloor animals, there will not be a high biomass down there probably.
