For this project we propose to delineate and map pelagic habitats and assess habitat condition for select estuaries and coastal waters within the Gulf of Mexico utilizing satellite ocean color data from the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Sea-Viewing Wide-Field-of-View Sensor (SeaWiFS), MODIS sea surface temperature (SST) and salinity (derived from ocean color) and altimetry data from JASON-1. The MODIS SST and salinity data and JASON-1 altimetry data will be used in a 3-D modeling approach to establish bottom to surface temperature difference profiles. Salinity, temperature difference profiles and frontal probabilities will be used to classify pelagic habitats. Trophic status and photic quality will be used to measure habitat condition of the classified maps. Coastal and estuarine areas within the GOM have been identified based on availability of in situ data and end-user interest. The Governors' Action Plan for Healthy and Resilient Coasts identified the need to map coastal and marine habitats and make those maps accessible to managers. Pelagic maps will be validated using in situ data and made accessible on-line; therefore, this project directly supports the following GOMA actions: ID-1: Create and provide access to interactive habitat maps for priority Gulf of Mexico habitats. EIA-4: Implementation of the Coastal and Marine Ecological Classification Standard in the Gulf of Mexico. - Develop methods to classify remote sensing data into the CMECS classification - Develop CMECS-classified habitat data maps Specific objectives of this proposal are to: 1. Identify and assess water column classifiers for usefulness in delineating pelagic habitats; 2. Assess the utility of satellite remote sensing data and modeling to delineate and classify pelagic habitat types in select areas of the Gulf of Mexico; 3. Assess the utility of self-organizing map technology for delineating coastal habitats; and 4. Further develop classification standardization in the Gulf of Mexico.
