These data include digital sidescan sonar imagery, digital seismic-reflection data, and descriptions and analyses of piston and gravity cores. The data were collected during several different projects that addressed surficial and shallow subsurface geologic processes. Some of these data sets have already been published, but the growing interest in the occurrence and distribution of gas hydrates in the Gulf of Mexico warrants integrating these existing data and associated interpretations into a GIS to provide regional background information for ongoing and future gas hydrate research. Purpose: This GIS data layer contains an interpretive layer outlining the extent of the youngest depositional lobe on the Mississippi Fan that was mapped using the GLORIA sidescan sonar imagery Time_Period_of_Content: Time_Period_Information: Multiple_Dates/Times: Single_Date/Time: Calendar_Date: 19820202 Single_Date/Time: Calendar_Date: 19820224 Single_Date/Time: Calendar_Date: 19850806 Single_Date/Time: Calendar_Date: 19851022 Currentness_Reference: ground condition Status: Progress: Complete Maintenance_and_Update_Frequency: None planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -86.423326 East_Bounding_Coordinate: -85.015959 North_Bounding_Coordinate: 26.836068 South_Bounding_Coordinate: 26.117291 Keywords: Theme: Theme_Keyword_Thesaurus: USGS Metadata Identifier Theme_Keyword: USGS:fdff218c-9b73-4c42-87f1-f8b764469387 Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: U.S. Geological Survey Theme_Keyword: USGS Theme_Keyword: Woods Hole Science Center Theme_Keyword: WHSC Theme_Keyword: Coastal and Marine Geology Program Theme_Keyword: CMGP Theme_Keyword: Gulf of Mexico GIS database Theme_Keyword: ArcView Theme_Keyword: shapefile Theme_Keyword: polygon Theme_Keyword: U.S. Exclusive Economic Zone Theme_Keyword: EEZ Theme_Keyword: interpretation Theme_Keyword: depositional lobe Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: oceans Theme_Keyword: geoscientificInformation Theme: Theme_Keyword_Thesaurus: USGS Thesaurus Theme_Keyword: scientific interpretation Theme_Keyword: sea-floor characteristics Theme_Keyword: marine geology Theme_Keyword: geospatial datasets Place: Place_Keyword_Thesaurus: None Place_Keyword: Mississippi Fan Place_Keyword: Gulf of Mexico Place_Keyword: North America Place_Keyword: United States Access_Constraints: None Use_Constraints: Public domain data from the U.S. government are freely redistributable with proper metadata and source attribution.

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. The link to the larger work citation 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.
