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 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

Source_Contribution:
The GOIRIA sidescan sonar mosaic was used as the source from which to identify the depositional lobe in the Mississippi Fan on which the SeaMARC 1A sidescan sonar survey was conducted.
Process_Step:
Process_Description:
The GLORIA sidescan sonar mosaic was registered and displayed in ArcView. The interpretaiton of the extent of the depositional lobe was then interactively drawn over the mosaic to create the ArcView GIS layer.
