Description:
Abstract:
This line shapefile contains navigation of the lines for the multichannel seismic survey that was conducted in the Atwater Valley area of the Gulf of Mexico during USGS cruise G1-03-GM aboard the R/V Gyre in the Gulf of Mexico in May, 2003. The purpose of this cruise was to collect multichannel seismic data in support of USGS and Department of Energy gas hydrate studies. About 253 km of data were collected along 35 short lines in and around lease block Atwater Valley 14 on the floor of the Mississippi Canyon.
Purpose:
This GIS overlay is a component of the U.S. Geological Survey, Woods Hole Science Center's, Gulf of Mexico GIS database. The Gulf of Mexico GIS database is intended to organize and display USGS held data and provide on-line (WWW) access to the data and/or metadata.
