The Humboldt Current, also known as the Peru Current, is a cold ocean current that runs along the coasts of Chile and Peru, extending to the equator and the Galápagos Islands. Originating from the upwelling of deep, nutrient-rich waters, this current is vital to the marine ecosystem, creating one of the most productive fishing areas in the world. Its cold waters influence the coastal climate, generating fog, aridity, and lower-than-usual temperatures for these latitudes, giving rise to deserts such as the Atacama. It is also associated with climate phenomena like El Niño and La Niña.Wikipedia
