Areas of high acoustic backscatter on the SIS-1000 1999 USGS sidescan sonar image of the Upper Continental Slope study area offshore of Louisiana (HIGHBACKSCATTER.SHP)

This GIS is a component of the U.S. Geological Survey, Woods Hole Science Center's Gulf of Mexico GIS database for gas hydrates. This database is intended to organize and display sidescan sonar, seismic-reflection, and sediment sample information collected by the USGS as well as derivative interpretations that are relevant to ongoing hydrate studies in the Gulf of Mexico.
