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 shows the tracklines along which chirp seismic-reflection profiles were collected to aid in selecting coring sites during a cruise aboard the R/V MARION DUFRESNE in 2002. The cruise was conducted in the northern Gulf of Mexico (USGS Field Activity 02018) to recover cores for gas hydrate studies.
