Abstract

The Peru-Chile Current System (PCCS) is the combined name for the equatorward and poleward currents along the Chilean and Peruvian coasts. The PCCS is a “typical” eastern boundary current system with predominately coast parallel equatorward winds, intensive upwelling, and high biological productivity. An important peculiarity of the PCCS is its tight connection to the equatorial Pacific communicating the globally strongest mode of interannual variability, the “El Niño/Southern Oscillation”, into the region. In addition, at intermediate depths, the PCCS region hosts one of the most intense oxygen-minimum zones that reaches from the coastal areas into the open ocean and influences the ecology and biogeochemical cycling in the region.
