The current produced by the upwelling of cold water off the coasts of Chile and Peru is the Humboldt Current, also known as the Peru Current [c1][t1]. It is a cold-water current of the southeast Pacific Ocean that flows northward along the western coast of South America [t4][t5]. This current is characterized by its relatively slow and shallow nature and is a major upwelling system, making it one of the most productive marine ecosystems globally [t2][t4]. In contrast, El Niño is a warm current that periodically replaces the cold Humboldt Current, disrupting the upwelling process [c3][t7]. The Agulhas Current is a warm current in the Indian Ocean near Madagascar [c2], and the Canary Current is a cold current in the North Atlantic [t1][t2]. The Humboldt Current's nutrient-rich waters are vital for the fishing industries of Peru and Chile [t4].
