Identification of an upwelling zone by remote sensing and in situ measurements. Mejillones del Sur Bay (Antofagasta-Chile)
Luis Rodríguez, Víctor Marín, Martín Farías, Enrique Oyarce

Mejillones delSur is a bay located in the Chilean coast near the Tropic of Capricorn. Anoceanographic study was conducted during 1987-1988 to test the hypothesis thatthe bay is located near an upwelling center. Analysis of satellite SST,together with in situ data support the hypothesis. The results show thathigh levels of nutrients, associated with lower temperatures and low surfaceoxygen concentrations, occur during the year regardless of the season.
