Geological and geochemical contraints on the isotopic composition of interstitial waters from the Hydrate Ridge region, Cascadia Continental margin

Creator:

Tomaru, A. M., Matsumoto, R., Torres, Marta E., and Borowski, Walter S.

Abstract:

The isotopic compositions of interstitial waters collected from Hydrate Ridge during Ocean Drilling Program Leg 204 were measured to evaluate the fluid evolution of this accretionary prism. At shallow depths, the dissolved Cl- concentrations and δD and δ¹⁸O values of the interstitial water reflect changes in the salinity and the...

Microbial methane generation and gas transport in shallow sediments of an accretionary complex, southern hydrate ridge (ODP Leg 204), offshore Oregon, USA

Creator:

Claypool, George E., Milkov, Alexei V., Lee, Young-Joo, Torres, Marta E., Borowski, Walter S., and Tomaru, Hitoshi

Abstract:

Sediments at the southern summit of Hydrate Ridge display two distinct modes of gas hydrate occurrence. The dominant mode is associated with active venting of gas exsolved from the accretionary prism and leads to high concentrations (15%–40% of pore space) of gas hydrate in seafloor or near-surface sediments at and...
