Description:
Objective:During Year 1 of this Consortium for Estuarine Ecoindicator Research for the Gulf of Mexico (CEER-GOM) project, Pensacola Bay was studied using satellite, close-range hyperspectral, and water sampling data. The primary objectives of this research project are to study the spatio-temporal relationship between remote sensing data, chlorophyll-a, and turbidity. In collaboration with the Gulf Ecology Division (GED), we collected spectral signature data at 16 sampling sites over four monthly periods. These data were successfully linked with chlorophyll-a and other water quality parameters measured by GED. On the satellite data selection and processing, images that match the water sampling cruises were unavailable due to cloud cover. Satellite images were processed using spectral clustering technique and cross-validated using data from a concurrent water sampling cruise.
The major objectives of Year 1 of the project were to: (1) select suitable scenes and acquire high-resolution satellite images; (2) establish the relationship between in situ chlorophyll-a measures and image signature; (3) estimate chlorophyll-a for three estuaries and analyze its spatio-temporal pattern; (4) establish the relationship between in situ water turbidity measure and image signature; (5) estimate turbidity for three estuaries and analyze its spatio-temporal pattern; and (6) hold biannual meetings with CEER researchers and coastal 2000 managers.
