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. Purpose: This data set contains polylines that outline the crests of low-relief ridges mapped within the inner shelf of Long Bay.

Completeness_Report: Ridge crests were digitized based on swath bathymetric data collected offshore of Myrtle Beach, SC 1999-2003. No additions or modifications are planned. Logical_Consistency_Report: No additional checks for topological consistency were performed on the data. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Interpretation of ridge crests was derived from swath bathymetry and seismic-reflection data. The accuracy is dependent on the source data and is assumed to be that of DGPS (2 m). Lineage: Process_Step: Process_Description: Interpretations of the rideg crests offshore of the Grand Strand, SC were dervied from swath bathymetry and seismic-reflection profiles. Crests were hand digitized within ArcGIS 9.0 at a scale of approximately 1:75000.
