Creator:

Torres, Marta E., Bohrmann, Gerhard, Brown, Kevin, deAngelis, Marie, Hammond, Douglas, Klinkhammer, Gary, McManus, James, Suess, Erwin, and Trehu, Anne

Abstract:

Geophysical and biogeochemical processes associated with fluid venting from active and passive continental margins will receive significant scientific and economic attention into the next century and are of major societal relevance. An important unknown among these interrelated processes is the role played by methane gas hydrates, at and below the...

Geochemical observations on Hydrate Ridge, Cascadia Margin during R/V BROWN-ROPOS cruise : August 1998

Creator:

Torres, Marta E., Brown, Kevin, Collier, Robert W., deAngelis, Marie, Hammond, Douglas, McManus, James, Rehder, Gregor, and Trehu, Anne

Abstract:

A massive release of methane on the Cascadia Hydrate Ridge was documented during a ROPOS program in August 1998, consistent with previously reported observations in 1996. An extensive survey of the seafloor revealed that the seeps lie within a narrow band trending 109 degrees. This feature parallels larger mounds imaged...
