      <abstract>This GIS overlay is a component of the U. S Geological Survey, Woods Hole Field Center's, Gulf of Mexico ArcView GIS database. The Gulf of Mexico GIS database is intended to organize and display USGS held data and provide on-line (WWW) access to the data and/or metadata.</abstract>
      <purpose>This ArcView GIS layer is a 250m version of the composite Gulf of Mexico GLORIA sidescan sonar mosaic.</purpose>
      <supplinf>This version of the image has an "ice blue" background surrounding the mosaic area. This image is used with the ArcView project views.</supplinf>

        <procdesc>This metadata file was edited for inclusion in the CMHRP metadata inventory. These edits included but are not limited to converting the metadata from HTML to XML format; adding information to the title to distinguish it from another dataset in the publication; fixing the publication date; added additional information in the identification section such as adding the series information, larger work ctation as well as the online links. Added the ISO 19115 Topic Category and USGS Thesaurus and appropriate terms; added the full URL to the browse graphic; specified that the information was not available from the original metadata in some of the fields; added links to the source contributions as well as trying to improve some of the information; updated the distribution liability with an FSP approved statement; added the online digital transfer option and links; updated the metadata date; provided a generic email and contact instructions in the metadata contact section; fixed all errors. A persistent identifier (PID) was added to the metadata in the thesaurus section. (20250813)</procdesc>
