Abstract
Several years of sea surface temperature data (19972003) for the coast of Antofagasta Baya semi-enclosed bay in northern Chilewere analyzed in order to f...

The warm waters of Antofagasta Bay are clearly evident in satellite imagery
We have shown that this is a permanent feature, with surface waters persistently warmer than along the open coast. Though this warm feature is found immediately downwind of Jorgillo Point, the maximum temperatures are found at La Rinconada at the downstream end of the bay
Summary
Las surgencias costeras derivadas del viento se observan a lo largo de muchas costas del mundo. Son fuertes y persistentes en las principales regiones de surgencia frente a costas de latitudes medias de los mayores continentes (e.g., el Sistema de Humboldt frente a las costas de Chile y Perú), y resulta en el enfriamiento y el enriquecimiento del medio ambiente marino, el cual se caracteriza por altos niveles de productividad y biomasa (Fonseca y Farías 1987, Barbieri et al 1995). Wind-driven coastal upwelling is observed along many coasts worldwide It is strong and persistent in the major upwelling regions found off the mid-latitude west coasts of major continents (e.g., the Humboldt System off the coasts of Chile and Peru) and results in cold, nutrient-rich marine environments characterized by high levels of productivity and biomass (Fonseca and Farías 1987, Barbieri et al 1995). Estos lugares y estas escalas de tiempo se caracterizan por un calentamiento de las aguas superficiales, a medida que el flujo de calor positivo hacia el océano calienta rápidamente la superficie del mar en la ausencia de vientos de surgencia y de mezcla vertical
