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 tracklines for sidescan-sonar system acquired by the U.S. Geological Survey during geophysical cruises offshore of the Grand Strand, SC.

Layback of the tow-fish was estimated; total error is 10 m. Logical_Consistency_Report: No additional checks for topological consistency were performed on the data. Completeness_Report: These data contain all of the sidescan-sonar trackline navigation collected during USGS work offshore of Myrtle Beach, SC 1999 - 2003. Any spurious data were removed during processing. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: All systems were navigated using Differential GPS. The sidescan-sonar system is towed at some distance behind the vessel. Slant-range distance is recorded. However, due to some uncertainty, horizontal accuracy is assumed to be 10 m. Lineage: Process_Step: Process_Description: Navigation was extracted from the sidescan-sonar data (raw *DAT format) and formatted as ASCII files for input to ArcGIS.
