Total suspended solids, along with chlorophyll-a concentrations are important components of the Galveston Bay waters. However, acquiring sufficient in situ measurements to characterize a water body as large as Galveston Bay is very difficult. This study seeks to overcome this problem by acquiring ground truth from throughout the bay which is then correlated to representative pixels of a remotely-sensed image. Imagery from the NASA AVHRR satellite is the remotely-sensed data being used in the study. Once the correlation is established, only AVHRR data will be needed to study changes in suspended solid and chlorophyll-a concentrations. This information will aid various agencies in understanding the origin, transport, and impact of sediment in the Bay. Furthermore, because AVHRR data have been archived for over two decades, historical trends in suspended sediment and chlorophyll-a concentrations can be established.
