We thank Rich Young with the USGS and Dave Bennett with Eckerd College, captains of the R/V G.K. Gilbert, for their help in the data collection; BJ Reynolds with the USGS, in St.Petersburg, Fla. for his contribution to the data collection process; Dave Foster and Jenna Hill, of the USGS Seafloor Mapping Group in Woods Hole, Mass. for providing examples of their archives; Jon Childs with the USGS, in Menlo Park, Calif. who provided examples of his formal metadata; Brock Murch and Bryan McCloskey at the USGS, in St.Petersburg, Fla. for their programming efforts in editing the navigation files; Shawn Dadisman at the USGS, in St.Petersburg, Fla. for her help with the content and layout; Trent Faust and Rob Wertz with the USGS in St. Petersburg for their help in the web design and technical layout of the CD-ROM; and Laura Moore and Jack Kindinger also both with the USGS in St.Petersburg, Fla. for their technical and editorial reviews.
Marine seismic reflection data are used to image and map sedimentary and structural features of the seafloor and subsurface. These data are useful in mapping the extent and thickness of shallow sedimentary units in the near shore region of South Carolina and in assessing other submarine geologic characteristics and features. The main objective of this cruise was to determine the characterization of the geological framework in the near shore region, between Little River Inlet to the entrance of Winyah Bay, for ongoing erosion studies.
Are there legal restrictions on access or use of the data?Access_Constraints: None. These data are held in the public domain.
Use_Constraints:The U.S. Geological Survey request to be acknowledged as the originator of the data in future products or derivative research.

| Data format: | The SEG-Y standard format (Barry and others, 1975) consists of the following: a 3600-byte reel identification header with the first 3200 bytes consisting of an ASCII header block and a 400-byte binary header block. Both headers include information specific to line and reel number. The trace data block follows the reel identification header. The first 240 bytes of each trace block is the binary trace identification header. The seismic data samples follow the trace identification header. in format SEG-Y Size: 650 |
