Sentences with phrase «methane hydrate systems»

Response of Methane Hydrate Systems to Environmental Change.

These new projects, managed by the Energy Department's National Energy Technology Laboratory, will focus research on field programs for deepwater hydrate characterization, the response of methane hydrate systems to changing climates, and advances in the understanding of gas - hydrate - bearing deposits.

Not exact matches

«But it's not like the hydrates are just building up over time, because we're also losing methane out of these systems.»

Even if engineers could construct a system to bring a load of hydrate to the surface before it disappeared, extracting the methane from the matrix of mud and rock would still present a problem.

We don't know that anthropogenic global warming will be limited before the system goes into runaway positive feedback driven by melting methane hydrates we can't control.

Pachauri outlined the potential for major changes to the climate system, which could overwhelm human response strategies - breakdown of the thermohaline circulation, disintegration of the West Antarctic Ice Sheet, a shift in mean climate towards an El Nino - like state, reduced carbon sink capacity, methane release from hydrates, and a rearrangement of biome distributions.

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.

Indeed, the long lifetime of fossil fuel carbon in the climate system and persistence of the ocean warming ensure that «slow» feedbacks, such as ice sheet disintegration, changes of the global vegetation distribution, melting of permafrost, and possible release of methane from methane hydrates on continental shelves, would also have time to come into play.

Dramatic warming and upheaval of the carbon system at the end of the Paleocene Epoch have been linked to massive dissociation of sedimentary methane hydrate.

They report that these methane hydrates were found in «coarse - grained sand - rich depositional systems in the Krishna - Godavari basin» and are more easily mined than the methane hydrates off the United States continental shelf.

They claim that salt allows the methane hydrate deposits to be at the «triple point» of the system making the system much more temperature sensitive than low salt deposits.

Archer et al. (13) provide evidence that methane hydrates in deep - sea sediments should be regarded as TE in the climate system.
