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. This data set contains locations and interpretations from 158 boreholes used to investigate subsurface stratigraphy within the lower coastal plain of South Carolina's Grand Strand region. en 2003 ground condition Complete None planned -79.361722 -78.586960 33.892672 33.252389 -79.361722-78.58696033.25238933.892672 General U.S. Geological Survey USGS Woods Hole Science Center WHSC Coastal and Marine Geology Program CMGP Point Shapefile sediments coastal plain stratigraphy boreholes Cretaceous Tertiary Quaternary locations ISO 19115 Topic Category location geoscientificInformation General South Carolina Grand Strand North Myrtle Beach Myrtle Beach Surfside Garden City Pawleys Island Waites Island Southeast United States United States Atlantic Ocean None Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.

All available interpretations of borehole information are included in this data set. Navigation was by differential GPS; positional accuracy to less than 10 m Sediment tailings and geophysical logs from boreholes were analyzed for biostratigraphy (i.e. shell and coral material) and lithologic character to determine the elevations of major stratigraphic boundaries.
