Previous work along the U.S. Atlantic coast shows that the structure and composition of older geologic strata located seaward of the coast heavily influences the coastal behavior of areas with limited sediment supply, such as the Grand Strand. By defining this geologic framework and identifying the transport pathways and sinks of sediment, geoscientists are developing conceptual models of the present-day physical processes shaping the South Carolina coast. The primary objectives of this research effort are: 1) to provide a regional synthesis of the shallow geologic framework underlying the coastal upland, shoreface and inner continental shelf, and define its role in coastal evolution and modern beach behavior; 2) to identify and model the physical processes affecting coastal ocean circulation and sediment transport, and to define their role in shaping the modern shoreline; and 3) to identify sediment sources and transport pathways; leading to construction of a regional sediment budget.

Horizontal accuracy is assumed to be 2 m. No additional checks for topological consistency were performed on the data. All shot point navigation for boomer seismic-reflection system during USGS field efforts offshore of Myrtle Beach, SC is represented. Any spurious navigation fixes were removed during processing. All systems were navigated using Differential GPS. Horizontal accuracy is assumed to be 2 m. Navigation was extracted from the seismic data (raw SEG-Y format) and formatted for input to ArcGIS. 2004 Jane Denny U.S. Geological Survey Geologist mailing and physical address
