Sentences with phrase «gas hydrate dissociation»

The researchers were able to date the shells precisely to the time when, according to the model calculations, the largest gas hydrate dissociation event occurred.

The numerical simulations of the seafloor also showed that the pockmarks in Nyegga are likely associated with this phenomenon because they are located right in the area of the largest gas hydrate dissociation event at the end of the Ice Age.

Knowledge of the timescales of gas hydrate dissociation and subsequent methane release are critical in understanding the impact of marine gas hydrates on the ocean — atmosphere system, says Shyam Chand, researcher at NGU / CAGE.

A team of researchers from the GEOMAR Helmholtz Centre for Ocean Research Kiel together with colleagues from Bergen, Oslo and Tromsø (Norway), have now discovered that large - scale sedimentation caused by melting of glaciers in a region off Norway has played a greater role in gas hydrate dissociation than warming ocean waters.

Contribution of oceanic gas hydrate dissociation to the formation of Arctic Ocean methane plumes

Reference: K. Wallmann, M. Riedel, W.L. Hong, H. Patton., A. Hubbard, T. Pape, C.W. Hsu, C. Schmidt, J.E. Johnson, M.E. Torres, K. Andreassen, C. Berndt, and G. Bohrmann, 2017: Gas Hydrate Dissociation off Svalbard Induced by Isostatic Rebound rather than Global Warming.

Applications are sought for research to clarify gas hydrate's role in the global natural environment, with specific emphasis on research that synthesizes existing insights and information to clarify the potential for significant feedbacks to warming climates (and attendant implications for ocean and atmospheric chemistry and geohazards) from climate - driven gas hydrate dissociation.

Still, geochemical data from carbonate blocks collected from these pockmarks indicate a methanogenic origin linked to gas hydrate dissociation and past fluid venting at the seafloor.
