Driscoll, N.W. 2007 1.0 Open-File Report 2005-1346 Reston, VA U.S. Geological Survey https://pubs.usgs.gov/of/2005/1346/ 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.

Horizontal accuracy is assumed to be 2 m. No additional checks for topological consistency were performed on the data. These data contain all of the boomer seismic-reflection trackline data collected during USGS work offshore of Myrtle Beach, SC 1999 - 2003. Any spurious data were removed during processing. All systems were navigated using Differential GPS. Horizontal accuracy is assumed to be 2 m. Navigation was extracted from the seismic data (raw SEG-Y format) and formatted for input to ArcGIS. 2004 Jane Denny U.S. Geological Survey Geologist mailing and physical address

Woods Hole MA 02543-1598 USA 508-548-8700 x2311 508-457-2310 jdenny@usgs.gov Edits to the metadata were made to fix any errors that MP v 2.9.36 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.). Attempted to modify http to https where appropriate. Fixed the date format in the time period of content. 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. 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. 20170215 U.S. Geological Survey VeeAnn A. Cross Marine Geologist Mailing and Physical
