Peru Current, an ocean current in the eastern Pacific Ocean. It is also known as the Humboldt Current, after Alexander von Humboldt, who discovered it in 1802. The Peru Current originates in the West Wind Drift in Antarctic waters and flows north along the west coast of South America. Just south of the Equator it flows west to join the South Equatorial Current.
The southeast trade winds blow warm surface water away from the coast and this is replaced by colder water, which moves up from moderate depths. This water is laden with nutrients that support one of the most abundant populations of seabirds and marine life in the world.
