Our efforts have focused on the development, demonstration and evaluation of an integrated adaptive sampling and modeling system for nowcasting and forecasting the 3-dimensional evolution of the physical and optical properties in the nearshore coastal ocean. Optical data is used to provide inputs to a suite of newly developed ocean color algorithms providing estimates of both biological (phytoplankton, particulate organic carbon) and chemical (colored dissolved organic matter) material. The optical data at LEO-15 is collected by a flexible array of in situ assets (including ships, robotic moorings and autonomous AUVs). During the 1999 summer experiments the impact of coastal upwelling on bulk apparent and inherent optical properties was quantified and related to phytoplankton biomass and composition. The measured optical properties were used as inputs to the Hydrolight radiative transfer model (RTE) and provided estimates of remote sensing reflectance. These model estimates were compared to satellite-derived estimates. Quantitative agreement between the SeaWiFs-measured and in-water modeled remote sensing reflectance was good, but results were variable depending on the specific reflectance model being used. The ocean color satellite data however, was limited by the revisit schedule of the SeaWiFs ocean color satellite. By accessing data from the growing constellation of ocean color satellites there is the potential to increase the observations of biological and chemical constituents on a time scale more commensurate with current hydrographic/atmospheric observations. To this end during the summer 2000 experiments, we began collecting data from both SeaWiFs and the Chinese FY1-C in order to minimize site revisit intervals and provide coverage in both the morning and afternoon. The real-time data allowed for optimization of field sampling efforts. In turn, the collected optical data was used to validate and cross-calibrate the products from both satellites.
