The objective of this project is to demonstrate the utility of NASA Earth science products in addressing the priority issue "Water Quality for Healthy Beaches and Shellfish Beds" identified by the Gulf of Mexico Alliance and thereby improving beach water quality management in coastal Louisiana and in the Gulf of Mexico region as well. To that end, two decision-making support tools will be developed: (1) Sensor-Assisted Nowcasting Environment for Beachgoers (SANE Beachgoers) and (2) Sensor-Assisted Forecasting Environment for Beaches (SAFE Beaches). The SANE Beachgoers reduces the decision-making time from 2 - 3 days to near real-time due to the support of statistical models, wireless water quality sensor station, and web-enabled GIS platform, significantly improving the decision-making in beach management and use. The SAFE Beaches changes the decision-making time from 2 - 3 days behind to 1 - 3 days ahead of actual use of beaches due to the identification of priority source areas and mapping of watershed time of concentration and to the use of weather forecast information. Roughness parameters involved in the time of concentration is estimated from MODIS/Terra Land Cover data. An essential component of SAFE Beaches and this project is priority source-area tracking of fecal indicator bacteria using the novel runoff fingerprinting (ROF) method. The ROF method is based on mapping of Fisher information that is computed using temporal changes in multiple band surface reflectance values of consecutive MODIS Aqua and Terra visits. The newly defined Fisher information provides the tool that is able to link various band reflectance values together and form an integrated remote sensing information system for coastal systems like beaches and watersheds. Consequently, this project will provide an innovative and practicable application of NASA EOS MODIS data in supporting beach management, recreational planning, and decision-making activities in the Gulf of Mexico Region.
