Why was the data set created?

Image shoreface and inner shelf off Folly Beach, SC

How was the data set created?

1. From what previous works were the data drawn?
2. How were the data generated, processed, and modified?

   Date: 1996 (process 1 of 2)

   All data were collected with a range of 100 m per side. All times are recorded in Universal Time Coordinated (UTC).

   Date: 30-Sep-2021 (process 2 of 2)

   The metadata from the Open-File report was edited to remove errors as well as update some information. Edits include updating the citation section with the OFR information, fixed the time period of content to cruise dates, added supplemental information with link to the field activity page on CMGDS, added the USGS Thesaurus and ISO 19115 Topic Category thesaurus, added keywords section with USGS persistent identifier as theme keyword, removed browse graphic section – since there isn’t one included in the report (information was pointing users to an obsolete system), removed empty source information in the lineage section, filled out the blank field for the NAD83 horizontal coordinate system, used a generic email address in metadata, updated digital transfer information, replaced distribution liability with FSP statement, replaced the first process step of “unknown” with cruise information. Other blank fields were deleted. The metadata date (19981116), but not the contact (except email) was updated. Those edits were performed 20210816. The metadata available from a harvester may supersede metadata available from the publication. Compare the metadata dates to determine which metadata file is most recent. Modified the originator from: United States Geological Survey (USGS) Coastal and Marine Geology Program Woods Hole Field Center (WHFC) 384 Woods Hole Road Woods Hole, MA 02543-1598 to U.S. Geological Survey. Also modified the metadata contact organization to the same value (20210930). Person who carried out this activity:
