The
Humboldt Current is a cold, low-
salinity ocean current that flows north along the west coast of South America from the southern tip of
Chile to northern
Peru. Also called the
Peru Current, it is an
eastern boundary current flowing in the direction of the
equator, and can extend 1,000 kilometers offshore. The Humboldt Current Large Marine
Ecosystem (
LME), named after the
Prussian naturalist Alexander von Humboldt, is one of the major
upwelling systems of the world, supporting an extraordinary abundance of marine life. Upwelling occurs off Peru year-round but off Chile only during the spring and summer, because of the displacement of the subtropical center of high pressure during the summer.
