ResumoCoastal areas of Southeast Brazil present a wealth of natural resources and are rich with diverse species, habitat types, and nutrients. They also sustain a diversity of economic activities being subject to increasing pressures such as urban development, industrial expansion, exploitation of natural resources, and tourism. With the aim of understanding and addressing the consequences of natural and anthropic forces in coastal waters of the South Brazil Bight, time-series of remote sensing and in-situ environmental observations are being developed to account for the interconnectivity of processes within the system. This paper deals with some results of a study of the bio-optical variability at the ANTARES time series station near Ubatuba (23°44S 45°00W). Ubatuba inner shelf is influenced by mesoscale cyclonic meandering of the Brazil Current (BC) system at a region with a crosscurrent transfer of slope waters into the shelf. This ecosystem is strongly influenced by the South Atlantic Central Water (SACW) upwelled locally or remotely forced from northeastern upwelling cores mainly during austral summer. In the winter, colder, less saline and relatively richer waters advects northwards along the shelf, from southern latitudes. The data set includes monthly measurements of chlorophyll-a concentration (CHL), absorption by particles, detritus, and colored dissolved organic matter (CDOM), above-water reflectance, CTD, nutrients, and primary production, collected during December 2004 - December 2008. A triangular diagram, based on the relative contribution to spectral absorption of the optically active constituents, is used to classify the waters, revealing CDOM-dominated Case 2 waters. Seasonal changes in water composition and optical properties are examined. Applying the OC2v4, OC4v4, and OC3M algorithms to the radiometric data, after proper spectral integration, the CHL estimates are generally too high compared with fluorometric determinations, which might be caused by relatively large CDOM absorption at the coastal site. Since most local processes in the coastal seas are linked to regional or even global processes it is necessary to monitor not only the area of immediate interest but also the far field in order to understand the local development. Remote sensing is the only possibility to continuously cover large areas with a high spatial and temporal resolution. Time series of satellite-derived CHL and sea surface temperature (SST) obtained by different orbital sensors (AVHRR, SeaWiFS, MODIS and MERIS) were compared. The time series analysis considered monthly averages of different periods, the largest being 1985-2008, including trend analyzes, climatological means and anomalies. In general, the sensors presented a reasonable agreement, but some discrepancies must be considered. Regarding the temporal variability it was possible to identify seasonal dynamics, inter-annual and decadal oscillations. The early results of such a comprehensive dataset indicate the potential and capabilities of the combined satellite/in situ approach in rendering a picture of bio-optical variability.
