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 locations and textural information of surface grab samples collected within the 1999 - 2003 survey area, offshore of the Grand Strand, SC.

Completeness_Report: All of the surface grab samples collected were processed for textural analysis. All textural information is included. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: DGPS is assumed to be accurate within 1-2 meters. Standard GPS is assumed accurate within 5-10 meters. Unless noted, all GPS/DGPS data is referenced to WGS84 (NAD83). Accuracy of sample locations is assumed to be comparable to DGPS accuracy (+ 2 m). Lineage: Process_Step: Process_Description: The grab samples were acquired with a shipek grab sampler by Coastal Carolina University. Surface sediments were sub sampled for textural analysis.
