This report presents the results of a three-year study of suspended sediments within the South Texas OCS region. The investigations were a part of the environmental studies of the South Texas Outer Continental shelf sponsored by the Bureau of Land Management. The physical properties of the suspended particulate system studied were the turbidity of the water and the texture of the suspended particulates. The objective of the study was to determine the spatial and temporal variability in the distribution of suspended sediments in an effort to gain insight into the regional sediment transport system.
