Integrated Ocean Drilling Program Expedition 311

Completed
By Central Energy Resources Science Center April 15, 2005

In 2005 a transect of four sites (U1325, U1326, U1327, and U1329) across the northern Cascadia margin was established during Integrated Ocean Drilling Program Expedition 311 to study the occurrences and formation of gas hydrate in accretionary complexes.  In addition to the transect of sites, a fifth site (U1328) was established at a cold vent with active fluid and gas flow. 

The four transect sites represent different stages in the evolution of gas hydrate across the margin from the earliest occurrence on the westernmost first accreted ridge (Site U1326) to its final stage at the eastward limit of gas hydrate occurrence on the margin in shallower water (Site U1329).
