What is an upwelling?
Quick Answer
An upwelling is the movement of cold, nutrient-rich water from deep ocean layers up to the surface.
The Full Story
Upwelling usually happens when winds push surface water away from a coast or along the equator, allowing deeper water to rise and replace it. This nutrient-rich water fuels phytoplankton growth, which supports fish, seabirds, and marine mammals. Major upwelling zones include the coasts of Peru, California, northwest Africa, and parts of the Arabian Sea. These areas are some of the most productive fishing grounds in the world.
