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.

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). Logical_Consistency_Report: Additional checks for topologic consistency were conducted to ensure polygon boundaries close, and neighboring polygons share borders. Completeness_Report: These data include all grain size information. Grain size distribution is represented as polygons. All data were included in the analysis. 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). Sediment statistics at each sample location were used to generate the grain size polygons. Lineage: Process_Step: Process_Description: The grab samples were acquired with a shipek grab sampler by Coastal Carolina University. Textural analyses were conducted by Coastal Carolina University and the USGS. Processing occurred 2000 to 2002.

This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The link to the data in the Identification_Information section had to be fixed. The link to the data in the Distribution_Information section had to be fixed. Modified online links to point to pubs.usgs.gov. Fixed process date format. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
