Title: Lower Altamaha River Spartna alterniflora aboveground biomass estimates from Landsat 5 TM imagery
Abstract: We used gap-filled monthly observations of Spartina alterniflora aboveground biomass derived from Landsat 5 and Landsat 8 satellite imagery from 1984-2018 to analyze temporal patterns in biomass in comparison to air temperature, precipitation, river discharge, nutrient input, sea level, and drought index for a southeastern US salt marsh. Satellite imagery data were downloaded from the USGS Earth Explorer data portal and initially processed with L3Harris Geospatial ENVI software. This database contains the estimates of above-ground Spartina alterniflora biomass within the freshwater tidal reach of the Altamaha River estuary on the Southeastern Atlantic coast of Georiga, USA. Work is ongoing to expand these data to cover the entire Georgia coast.
