Purpose | 1) To determine the timing and cause of submarine slumps at the frontal ridge; 2) to investigate the role of gas hydrate in the mechanisms controlling and responding to submarine slumping; and 3) to determine the potential for fluid and gas venting and formation of gas hydrate in and around the slump sites. | ||||||||
Location | Cascadia margin, Vancouver Island, Canada, North Pacific;48.60 deg N 127.04 deg W;Barkley Canyon, Vancouver Island, Canada, North Pacific;48.31 deg N 126.06 deg W; | ||||||||
Summary | Acquired pore water and sediment samples for numerous chemical and isotopic analyses to aid in interpreting the cause and history of submarine landslides along the base of the Northern Cascadia Margin and the cycling of methane carbon and higher hydrocarbons at several mid-slope seep sites. About 75% of the pore water samples collected have been analyzed for sulfate and chloride concentration. | ||||||||
