Presented at the 2015 Aquarius/SAC-D Science Team MeetingThe Argentine shelf and its shelf-break comprise a large and rich biological area of the ocean. This is one of the widest and ï¬attest continental shelves in the world ocean characterized by the presence of water masses with different properties due to the presence of algal blooms, coastal upwellings, shelf-break and tidal fronts, and river discharges. Remote sensing of ocean color has demonstrated to be a very useful tool for monitoring the marine ecosystem providing near real-time, long-term, synoptic, global estimates of key parameters, such as surface chlorophyll-a (chl-a) concentration. Strong efforts have been recently put in collecting bio-optical data, including radiometric and inherent optical properties measurements. This invaluable and scarce information will help improving atmospheric correction algorithms, as well as validating and calibrating satellite-derived products of current and future ocean colour missions like the Argentinean-Brazilian joint ocean colour satellite mission SABIA/Mar. In this presentation we will show the main results of different bio-optical studies that have been performed in the Argentine Sea. These include the validation of satellite-derived products and algorithms, the development of a general turbidity algorithm, the evaluation of atmospheric correction algorithms in the extreme turbid waters of RÃo de la Plata river, and primary production modeling using field and remotely sensed data.
