Examination of Abiotic Drivers and Their Influence on Spartina alterniflora Biomass over a Twenty-eight Year Period Using Landsat 5 TM Satellite Imagery of the Central Georgia Coast
… biomass to landscape level estimates using 294 Landsat 5 TM scenes acquired between 1984 and 2011. For each scene we extracted data from the same 63 sampling polygons, containing 1222 pixels covering about 1.1 million m2. Using univariate and multiple regression tests, we compared Landsat …

Detecting long-term trends in water quality parameters using remote sensing techniques
… I evaluated the use of moderate resolution Landsat-5 TM imagery for estimating three indicators of water quality: Secchi depth (SDD), chlorophyll-a concentration (Chl-a), and dissolved organic carbon (DOC). Reflectance and in situ data were collected within seven days of satellite overpass …
