- Abstract:
-
In 1999, the USGS, in partnership with the South Carolina Sea Grant Consortium, began a study to investigate processes affecting shoreline change along the northern coast of South Carolina, focusing on the Grand Strand region. 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 polygon shapefile outlining grain size distribution throughout the 1999 - 2003 survey area, offshore of the Grand Strand, SC.

-
Interpretations of grain size distribution are based on sample textural information, sidescan-sonar imagery, swath bathymetry and seismic data. The mean grain size of surficial sediment samples were used to generate the grain size polygons. These data were manually interpreted and digitized at a scale of 1:75,000 (regional interpretation).
- Completeness_Report:
-
These data include all grain size information. Grain size distribution is represented as polygons. All data were included in the analysis.
- Logical_Consistency_Report:
-
Additional checks for topologic consistency were conducted to ensure polygon boundaries close, and neighboring polygons share borders.

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). Sediment statistics at each sample location were used to generate the grain size polygons.
