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; 3) To
determine the potential for fluid and gas venting and formation of
gas hydrate in and around the slump sites.

|
Summary
|
Acquired pore water and sediment samples for numerous
chemical and isotopic analyses to add 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.
