The image was created from the geologic interpretations of the GLORIA images that may be found in the paper atlases that were 500,000 and are referenced as U.S. Geological Survey Miscellaneous Investigations Series I-1864-A,B (1987). https://doi.org/10.3133/ofr0019 https://pubs.usgs.gov/of/2000/of00-019/htmldocs/data.htm Valerie F.

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. This ArcView shapefile an additional GIS overlay. It contains the names of various seafloor features (basins, slopes, knolls, ridges, etc.) for the Gulf of Mexico. This ArcView shapefile was created from a Microsoft Excel spread sheet found at the National Oceanic and Atmospheric's National Geophysical Data Center's website. The information contained in the spread sheet was editted to include only those features that would pertain to the planned Gulf of Mexico Internet Map Server for the USGS, Woods Hole Field center. Therefore, this is not a complete listing as would be found from NOAA-NGDC. 1999 Publication Date Complete Unknown -97.5 -79.9167 31.00000 23.50000 USGS Metadata Identifier USGS:7e0329e6-f6cf-4455-ab0f-b653446fad49 None U.S. Geological Survey Woods Hole Field Center Gulf of Mexico database feature names seafloor features ArcView shapefile ISO 19115 Topic Category oceans USGS Thesaurus geospatial datasets geographic names None Gulf of Mexico None Although this derived data set and it's lineage dataset have been used by the USGS, no warranty, expressed or implied, is made by the USGS as to the accuracy of the data and/or related materials.

Edit 20250813: Although the link is to a NOAA site, there is a link from the main ibcca page to the Gazetter of Undersea Feature Names. The assumption is this might be the way the original author accessed the information. The Microsoft Excel datafile was downloaded from the NOAA-NGDC site and read into Excel. Records that did not contain a latitude/longitude coordinate for a feature name was deleted from the spreadsheet. The text fields containing the latitude and longitude coordinate of the seafloor feature were then copied and added to the spreadsheet as the first two fields. These fields were added so numeric latitude longitude fields recorded as signed decimal degrees could be created later. The modified spreadsheet was saved as a comma separated values text file. ib1234gz.xls 19990614 gomnames.csv U. S.

These edits included but are not limited to converting the metadata from HTML to XML format; 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; moved the original citation to a source contribution and added additional information; duplicate elements that caused errors were combined into a single element when appropriate; 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. No spatial reference information was provided with the original metadata file. A spatial reference section was added to be consistent with the other datasets in the publication. A persistent identifier (PID) was added to the metadata in the thesaurus section. (20250813) 20250813 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address
