Abstract: River-impacted coastal regions such as the northern Gulf of Mexico (nGoM) receive large fluxes of freshwater including dissolved and particulate materials that also support highly productive coastal ecosystems. These regions are also being increasingly impacted by extreme events such as storms and hurricanes making them hotspots of biogeochemical cycling. The application of standard empirical or semi-analytic ocean color algorithms to assess optical or
biological properties are often inadequate in these coastal waters. We have recently proposed adaptive ocean color algorithms to improve satellite estimates of optical-biogeochemical variables in these optically complex estuarine-shelf waters. The approaches implemented include adaptive: i) atmospheric correction (AD-ATCOR), ii) quasi-analytic (AD-QAA), and 3) chlorophyll (Chl_AD) algorithms. In this presentation we discuss these various adaptive approaches and their application to assess biogeochemical response to extreme events in the nGoM.
