Multi-sensor synergetic analysis of mesoscale oceanic features: Campos Basin, southeastern Brazil

This study presents a combined use of multi-sensor remote sensing and in situ data for the analysis and interpretation of oceanic features observed at the continental shelf and slope of the Campos Basin, southeastern Brazilian coast. Ocean color (SeaWiFS), thermal infrared (AVHRR), scatterometer (QuikSCAT) and SAR (Radarsat-1) data were integrated in order to associate the different SAR backscatter patterns to physical and biological forcing processes. The interpreted SAR feature included processes such as oceanic fronts, meandering and eddies, upwelling plumes, wind variability and algae bloom. The correct interpretation of these features was only possible through the use of the multi-sensor synergetic approach complemented by timely field verification.
