Journal ArticleDOI
Gas hydrate destabilization: enhanced dewatering, benthic material turnover and large methane plumes at the Cascadia convergent margin
Erwin Suess,Marta E Torres,Gerhard Bohrmann,Robert W. Collier,Jens Greinert,Peter Linke,Gregor Rehder,Anne M. Tréhu,Klaus Wallmann,Gisela Winckler,E. Zuleger +10 more
TL;DR: In this paper, the authors characterize a newly recognized mechanism of dewatering at convergent margins, where freshening of pore waters from hydrate destabilization at depth and free gas drives fluids upward.
Journal ArticleDOI
Fluid flow, methane fluxes, carbonate precipitation and biogeochemical turnover in gas hydrate-bearing sediments at Hydrate Ridge, Cascadia Margin: numerical modeling and mass balances
Roger Luff,Klaus Wallmann +1 more
TL;DR: A numerical model was applied to investigate and quantify biogeochemical processes and methane turnover in gas hydrate-bearing surface sediments from a cold vent site situated at Hydrate Ridge, an accretionary structure located in the Cascadia Margin subduction zone as mentioned in this paper.
Journal ArticleDOI
Anaerobic oxidation of methane above gas hydrates at Hydrate Ridge, NE Pacific Ocean
TL;DR: In this article, the authors analyzed surface sediments (0 to 10 cm) populated by chemosynthetic communities for AOM, sulfate reduction (SR), and the distribution of the microbial consortium mediating AOM.
Journal ArticleDOI
The oxygen isotope evolution of seawater: A critical review of a long-standing controversy and an improved geological water cycle model for the past 3.4 billion years
TL;DR: In this article, the authors present an updated compilation of marine carbonate δ18O from around the world, covering the Phanerozoic and Precambrian rock records.
Journal ArticleDOI
Gas hydrate growth, methane transport, and chloride enrichment at the southern summit of Hydrate Ridge, Cascadia margin off Oregon
Marta E Torres,Klaus Wallmann,Anne M. Tréhu,Gerhard Bohrmann,Walter S Borowski,Hitoshi Tomaru +5 more
TL;DR: In this paper, the authors developed a one dimensional, non-steady state, transport reaction model to simulate the observed chloride enrichment at Site 1249 and showed that in order to reach the observed high chloride values, methane must be transported in the gas phase from the depth of the BSR to the seafloor.
