Provenance, Stratigraphic Architecture, and Hydrogeologic Influence of Turbidites on the Mid-Ocean Ridge Flank of Northwestern Cascadia Basin, Pacific Ocean

Autor: Kimberley D. Hoke, Andrew T. Fisher, Glenn A. Spinelli, Michael B. Underwood, Earl E. Davis, Emily R. Giambalvo, Lars Zühlsdorff

Publikováno v: Journal of Sedimentary Research. 75:149-164

The northwestern edge of Cascadia Basin (North Pacific Ocean) is unusual because late Pliocene to Holocene turbidites lap onto juvenile oceanic crust of the Juan de Fuca Ridge. Subsidence of the ridge flank combines with irregular westward progradati

Hydrothermal circulation within the sea floor, through lithosphere older than one million years (Myr), is responsible for 30% of the energy released from plate cooling, and for 70% of the global heat flow anomaly (the difference between observed ther

Implications for focused fluid transport at the northern Cascadia accretionary prism from a correlation between BSR occurrence a d near-sea-floor reflectivity anomalies imaged in a multi-frequency seismic data set

Publikováno v: International Journal of Earth Sciences. 88:655-667

A high-resolution seismic survey was carried out at the accretionary prism on the continental slope off Vancouver Island, Canada. Two GI-Gun data sets with different source frequency ranges of 50–150 and 100–500 Hz were combined with 4 kHz narrow

An Improved Survey Evaluation and Design Workflow

Autor: Tommy Rasmussen, Endre Bergfjord, Åsmund Drottning, M. Branston, Håvar Gjøystdal, Lars Zühlsdorff

Publikováno v: 72nd EAGE Conference and Exhibition incorporating SPE EUROPEC 2010.

Modern survey evaluation and design (SED) projects usually include the generation of full seismic surveys followed by processing of the synthetic data. Yet, this approach is expensive and inflexible. Although this “brute force” approach may be un

Hydrothermal recharge and discharge guided by basement outcrops on 0.7-3.6 Ma seafloor east of the Juan de Fuca Ridge: Observations and numerical models

Autor: Lars Zühlsdorff, Carl W. Gable, M. Hutnak, Volkhard Spiess, Andrew T. Fisher, Philip H. Stauffer

Publikováno v: Geochemistry, Geophysics, Geosystems. 7

[1] The nature of ridge-flank hydrothermal circulation guided by basement outcrops protruding through thick sediments is constrained on the eastern flank of the Juan de Fuca Ridge using combined bathymetric, seismic, and thermal observations and anal

Sedimentation patterns, folding, and fluid upflow above a buried basement ridge: Results from 2-D and 3-D seismic surveys at the eastern Juan de Fuca Ridge flank

Autor: Volkhard Spiess, Lars Zühlsdorff

Publikováno v: Journal of Geophysical Research. 111

[1] During R/V Sonne Cruise SO 149, new two-dimensional (2-D) and 3-D multifrequency seismic data were collected at the eastern flank of the Juan de Fuca Ridge, off the west coast of North America. Two-dimensional overview lines indicate that turbidi

Seismic reflectivity anomalies in sediments at the eastern flank of the Juan de Fuca Ridge: Evidence for fluid migration?

Publikováno v: Scopus-Elsevier

A high-resolution seismic survey was carried out in the vicinity of Ocean Drilling Program (ODP) Leg 168 drill sites at the eastern flank of the Juan de Fuca Ridge. Three seismic systems with different source frequencies up to 4000 Hz were used simul
