Media Invited Onboard Oct. 31

An international team of Earth scientists, supported by the Integrated Ocean Drilling Program (IODP), has embarked on a six-week expedition off the coast of Vancouver Island to conduct research beneath the Earth's crust. Co-led by Tim Collett of the U.S. Geological Survey (Denver) and Michael Riedel of Natural Resources Canada, the Cascadia Margins Gas Hydrates, IODP Expedition 311, will investigate how high volumes of carbon and methane gasses trapped in gas hydrate deposits could effect climate change and seafloor stability.

Gas hydrates, ice-like solids composed of water and natural gas, are found under Arctic areas and on marine continental shelves. The science party boarded the JOIDES Resolution, IODP's U.S.-operated research drilling vessel on September 16, in Astoria, Oregon.

The ship comes into port at the expedition's conclusion at Victoria, British Columbia, on October 29, 2005.
