Significats de methane hydrate en anglès

As ocean temperatures change, the methane hydrate system has the potential to become unstable.

This image shows a chunk of burning methane hydrate.

It's where you heat the Earth to the point where the Arctic methane hydrate shelf starts to melt.

They'd also like to find out whether methane hydrate deposits vary in composition, concentration and behavior with depth.

Underneath the ocean surface way down deep, there are huge deposits of frozen methane gas, it's called methane hydrate.

Other countries including Canada, the US and China have been looking into ways of exploiting methane hydrate deposits as well.

But what worries Singer most is a rapid release of methane stored in sub-polar permafrost or in huge methane hydrate deposits under the sea.

Mahajan and others will study the samples to determine the nature of the methane hydrate in the sea floor and develop methods to estimate reserves.

Some scientists also fear a warmer world could release vast amounts of methane trapped in sub-polar permafrost or in methane hydrate deposits under the sea.

This field of silt covers a deep layer rich in methane hydrates.

Vast reserves of methane hydrates -a form of natural gas -could power the world for decades to come.

Before any major extraction efforts can go forward, more-reliable means of identifying the location and composition of methane hydrates are needed.

Ironically, methane hydrates are a promising future energy source in themselves, but researchers are still searching for ways to safely harness them.

It also bodes well for other forms of fossil fuels, such as methane hydrates and oil shale, once thought too expensive to develop.

Methane hydrate, a strange form of natural gas, has recently become a fascination for energy-hungry nations from the United States to Japan and India.

None of the models presented at the session included carbon dioxide emissions from unconventional fossil fuels like tar sands, methane hydrates or oil shale.
