Publication_Date: 2005 Title: GIS of selected geophysical and core data in the northern Gulf of Mexico continental slope collected by the U.S. Geological Survey Edition: 1.0 Series_Information: Series_Name: Open-File Report Issue_Identification: 2005-1071 Publication_Information: Publication_Place: Reston, VA Publisher: U.S. Geological Survey Online_Linkage: https://pubs.usgs.gov/of/2005/1071/ Description: Abstract: Since 1982 the U.S. Geological Survey (USGS) has collected a large amount of surficial and shallow subsurface geologic information in the deep parts of the Gulf of Mexico. 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 outlines the distribution of surface and nearsurface mass-wasting deposits within the SIS-1000 sidescan sonar study area. The interpretation used both the backscatter nature of the sidescan sonar imagery as well as the shallow subsurface character on seismic profiles to define the extent of these deposits.

Lineage: Process_Step: Process_Description: This interpretive layer shows the distribution of mass-wasting deposits within the SIS-1000 survey area. The shapefile was created in ArcView using SIS-1000 sidescan image (sis_engeog.tif) to interpolate between known areas of mass wasting that had been identified on the chirp high-resolution seismic profiles.

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.). The link to the data in the Distribution_Information section had to be fixed. 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.
