Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Location: Gulf of Mexico, United States, North America, North Atlantic;
Principal Investigator(s): David Twichell
Affiliate Investigator(s): Alan Cooper, USGS, Menlo Park
Data Type(s): Location-Elevation: Navigation, Location-Elevation: Transects, Seismics: Boomer, Seismics: Multichannel, Sonar: Sidescan
Scientific Purpose/Goals: Collection of regional high-resolution multichannel seismic data and Huntec seismic data as well as two detailed sidescan surveys to understand the distribution of gas hydrates on the upper continental slope in the Gulf of Mexico and their effect on sea floor processes.
Start Date: 1999-04-09
Start Port/Location: Galveston, TX
End Date: 1999-04-22
End Port/Location: Galveston, TX
Equipment Used: DGPS, SIS1000 Sidescan sonar, Benthos 7000 , Multichannel seismics, Boomer, Single channel hydrophone
Information to be Derived:
Summary of Activity and Data Gathered: Not all the gear was run all the time, so the amounts of individual data types (in km) are as listed: High-resolution MCS data - 1400 km; Huntec boomer data - 900 km; SIS-1000 sidescan and Chirp sub-bottom data - 500 km.
