Its turbid cold waters are home to the largest fish stocks in the world: the Humboldt Current system, which runs along the Peruvian and Chilean coasts, boasts exceptional biological productivity thanks to a very intense coastal upwelling phenomenon – ascents of deep nutrient-rich waters. Thanks to high-resolution models of the oceanic circulation and water oxygen content, IRD researchers and their partners have now quantified this ecosystem's sensitivity to various disturbances in the equatorial Pacific. This work should eventually enable a regional modelling platform to be set up integrating the oceanic, biogeochemical and atmospheric components of the Peru-Chile upwelling.
