Resumen:
The inner shelf of the southwest of Buenos Aires Province (Argentina) is a very complex natural system. It combines an heterogeneous bathymetry, the presence of an estuary and outflows of rivers, and a important input of energy produced by the tide and wind. A global study of diverse satellite products was made in order to obtain a dynamic regionalization of the study area. In addition the seasonal and inter-annual behavior of the sea surface temperature (sst), chlorophyll-a (chl-a) and inherent optical properties (IOPs) were analyzed and related to the hydrographic and climatological characteristics of the area. Nine years data of Moderate Resolution Imagery (MODIS) were processed in order to get the sst product. In situ data obtained from oceanographic campaigns were used to validate the results on the sst. Weakly and monthly composites of ten years of Sea Viewing Wide Field of View Sensor (SeaWiFS) were made in order to determine different regions based on Ocean Color derived chl-a and IOPs. Finally, the inter-annual and seasonal trend of the parameters were obtained with the Census X-11 method.
