Upwelling

Upwelling is a natural ocean process where deep, cold, nutrient-rich water rises to the surface. This occurs when winds blow along the coast, pushing surface waters away and allowing deeper water to replace them. The influx of nutrients supports the growth of plankton and marine life, making upwelling zones some of the most productive fishing areas. These regions often have cooler temperatures and increased biodiversity, playing a vital role in global ocean ecosystems and climate regulation.
