Off the coasts of Peru and Chile, cold water rises from the ocean floor in a process called upwelling, driven by the Humboldt Current. That rising water carries nutrients most tropical seas rarely receive, feeding one of the most productive marine ecosystems on the planet.
Dense schools of anchoveta support colonies of guano birds, sea lions, and Humboldt penguins along the coastline. Each year, humpback whales arrive from Antarctic waters to breed off the northern coast of Peru, following the same current that sustains everything beneath it.
None of this is visible from the beach. It's one of the most productive ocean systems on Earth, working just below where most people are standing.
