Drill Rig for Gas Hydrate Research off the Oregon Coast

During Ocean Drilling Program Leg 204, nine sites were cored and wireline logged on the Oregon continental margin to determine the distribution and concentration of gas hydrates in an accretionary ridge setting, investigate the mechanisms that transport methane and other gases into the gas hydrate stability zone, and obtain constraints on physical properties of gas hydrates in situ. This image shows the drilling rig on the Drillship JOIDES Resolution.
