USGS Coastal and Marine Geology Program

Coastal & Marine Geology Program

Field Activity Details for field activity 2005-017-FA

Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Location: Atwater Valley, Keathley Canyon, Gulf of Mexico, United States, North America, North Atlantic;

Principal Investigator(s): Deborah Hutchinson

Affiliate Investigator(s): GoM Hydrates JIP

Information Specialist(s): Brian Buczkowski

Data Type(s): Sampling: Geology, Location-Elevation: Navigation

Scientific Purpose/Goals: Cruise and project objectives include (1) calibrating geophysical estimates of location and concentration of hydrate and underlying free gas concentrations; (2) determining physical properties (e.g., strength, permeability, compressibility) of hydrate-bearing and underlying sediments in order to evaluate the relationship between gas hydrates, fluid flow, and sea floor/slope stability; (3) evaluating the sources and transport mechanisms for gas and the physical and chemical mechanisms of hydrate formation near the sea floor and at the base of the gas hydrate stability zone; (4) collecting samples of gas hydrate preserved at in situ pressures for investigation both during and post-cruise; (5) collecting and preserving pore water, gas, and sediment samples for post-cruise geochemical and microbiological investigations; and (6) developing a better basis for understanding the impact of gas hydrates on offshore petroleum drilling and production operations.

Vehicle(s):

Start Date: 2005-04-15

Start Port/Location: Mobile, AL

End Date: 2005-05-21

End Port/Location: Galveston, TX

Equipment Used: Well drilling, Starfix navigation system

Information to be Derived: Samples and chemical analysis; Grain size analysis;

Summary of Activity and Data Gathered: Pressurized drilling yielded 210.06 m of core from both Atwater Valley and Keathley Canyon sites. Various geochemical and physical properties analyses were performed on the cores, as well as non-invasive scans using IR cameras, MSCL scanners and X-ray imaging.
