Description:
Abstract:
In 1999, the U.S. Geological Survey (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 polygons that identify the geologic unit type present in outcrop or subcrop along the Long Bay inner shelf. Polygon areas are based upon digital interpretations of Chirp seismic reflection data and coastal plain boreholes. A polygon outlining the inner shelf study area was erased (ArcGIS Analysis toolbox)in iterations using polygons outlining gridded surfaces of Holocene surficial sediment (sedthick_grd)and paleochannel unconformities (paleoch_grd). Outside of the area covered by the Holocene surficial sediment grid, seismic data indicate surficial sediment cover of < 50 cm. In these areas, paleochannel fills, Cretaceous, and Tertiary units are interpreted to crop out at the sea floor, or subcrop near the surface.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. 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 was valid, but pointed to the wrong dataset. The link to the data in the Distribution_Information section had to be fixed. 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.
