The purpose of this cruise was to collect multichannel seismic data in support of USGS and Department of Energy gas hydrate studies. About 786 km of data were collected along 59 lines in and around lease block Keathley Canyon 195.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.en2003050320030516ground conditionAs needed-93.139346-92.58131327.58875626.724186-93.139346-92.58131326.72418627.588756Nonenavigationmultichannelsesimicline shapefileU.S. Geological SurveyUSGSCoastal and Marine Geology ProgramCMGPWoods Hole Science CenterWHSCfield activity number G1-03-GMfield activity number G103GMWHSC field activity serial number 03001cruise identifier TAMU03-G-4Information Archives Field Activity 03001NoneGulf of MexicoKeathley Canyonoceans and estuarieslocationISO 19115 Topic CategorygeoscientificInformationnonePublic domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.
