| Abstract | Oceanic applications of RADARSAT-1 data include: (1)mapping mesoscale currents and regional circulation patterns; (2)identifying frontal zones, internal waves, eddies, meanders, upwelling, shears, and wind fronts. The investigated site includes coastal and oceanic areas of the Campos Basin, where oil roduction and fishery activities take place. Oceanographic dynamics is intense, with a pronounced interaction between the Brazil Current (BC)and coastal upwelling waters. The BC is a tropical, warm and saline water mass, characterized by low biologic productivity; coastal upwelling is characterized by cold water and high biologic productivity. In the interface between the BC and upwelling areas, mean flow instabilities give rise to mesoscale features (e.g., frontal zones, eddies, and meanders). Data from the AVHRR (Advanced Very High Resolution Radiometer)sensor are used as an aid to the interpretation of RADARSAT-1 images for coastal and oceanic applications. The combined use of simultaneously acquired AVHRR and RADARSAT-1 data greatly enhances SAR imaging capabilities for the identification of oceanic currents relevant to offshore operations. The AVHRR (1.1 km by 1.1 km resolution)data acquisition took place on 28 December 1997, about 07:02 p.m. local time. A RADARSAT-1 ScanSAR Narrow 1 ascending image was obtained in the same day, about 07:28 p.m. local time. The Unsupervised Semivariogram Textural Classifier (USTC)was used to enhance textural domains on the RADARSAT-1 image. These features, when combined with Sea Surface Temperature (SST)maps obtained from the AVHRR data, perfectly outlined coastal upwelling waters and the inshore BC boundary (characterized by strong thermal gradients). This remarkable result demonstrates that strong thermal gradients in the SST image are expressed as sharp roughness boundaries in the USTC-classified RADARSAT-1 data. |
