The GA-SC Coastal Erosion Study is a USGS-funded cooperative project that seeks to understand the rates, controls and processes of coastal erosion within the Georgia Bight. Researchers at Skidaway Institute of Oceanography, Georgia Southern University, University of West Georgia and Pennsylvania State University collaboratively investigate these issues in a study region extending from St. Helena Sound, SC to St. Marys Inlet, GA. A State of Knowledge Report, involving the compilation and synthesis of existing data to evaluate the level of our understanding of shoreline change, coastal morphodynamics, shallow stratigraphic framework and geologic resources in the Georgia Bight, was one part of this larger project. This report documents basic and applied coastal research and coastal-engineering-related studies, identifies information gaps and significant deficiencies in our knowledge and prioritizes areas where opportunities exist for future geologic research pertinent to management of a dynamic coastal zone.
