North-south variability in the history of deformation and fluid venting across Hydrate Ridge, Cascadia margin

Creator:

Johnson, Joel E., Goldfinger, Chris, Tréhu, Anne M., Bangs, Nathan Lawrence Bailey, Torres, Marta E., and Chevallier, Johanna

Abstract:

Hydrate Ridge is an accretionary thrust ridge located on the lower slope of the central Cascadia convergent margin. Structural mapping based on two-dimensional and three-dimensional multichannel seismic reflection profiles and gridded bathymetry coupled with deep-towed sidescan sonar data and Ocean Drilling Program (ODP) biostratigraphy suggests that seafloor fluid venting patterns...

Feeding methane vents and gas hydrate deposits at south Hydrate Ridge

Abstract:

Log and core data document gas saturations as high as 90% in a coarse-grained turbidite sequence beneath the gas hydrate stability zone (GHSZ) at south Hydrate Ridge, in the Cascadia accretionary complex. The geometry of this gas-saturated bed is defined by a strong, negative-polarity reflection in 3D seismic data. Because...
