Humboldt Current
The Humboldt Current is a large marine ecosystem, named after the Prussian naturalist Alexander von Humboldt. It is one of the major nutrient systems of the world, bringing nutrients up into the surface waters of the ocean. This supports an extraordinary abundance of marine life.  Upwelling occurs off Peru year-round but off Chile only during the spring and summer. This is  because the subtropical center of high pressure is displaced during the summer.
