Sentences with phrase «contain gas hydrates»

Permafrost was known to contain gas hydrates — icelike mixtures of water and organic gases first identified in deep - sea sediments which form only at very high pressures and low temperatures.

Not exact matches

The U.S. Geological Survey estimates that methane locked in ice (known as hydrates) could contain more organic carbon than all the world's coal, oil, and nonhydrate natural gas combined.

One cubic meter of gas hydrate on the ocean floor contains 165 cubic meters of gas at room temperature and pressure.

Naturally - occurring methane hydrates, hidden deep under the sea floor or tucked under Arctic permafrost, contain substantial natural gas reserves locked up in a form that is difficult to extract.

They are associated with temporal changes in dissociation of gas hydrates - the icy substance that contains huge amounts of methane.

In many parts of the world, the seafloor contains natural gas trapped inside ice crystals called hydrates.

This glowing ledge showed that the mound contained methane hydrate, a lattice of frozen water that traps methane gas molecules within its icy cages.

They are associated with temporal changes in dissociation of gas hydrates — the icy substance that contains huge amounts of methane.

Gas yield calculations suggest that other ice - bearing cores from a corehole in the Niglintgak field also contained non-visible pore space gas hydraGas yield calculations suggest that other ice - bearing cores from a corehole in the Niglintgak field also contained non-visible pore space gas hydragas hydrate.

The methane release happens because the gas is freed from melting hydrates — an icy substance found below the ocean floor, containing methane in a cage of frozen water.

Gas hydrates contain huge amount of methane gas, and it is destabilization of these that is believed to have caused the craters on the Yamal PeninsuGas hydrates contain huge amount of methane gas, and it is destabilization of these that is believed to have caused the craters on the Yamal Peninsugas, and it is destabilization of these that is believed to have caused the craters on the Yamal Peninsula.

Ice sheets are heavy and cold, providing pressure and temperatures that contain methane in form of ice - like substance called gas hydrate.

The sedimentary methane hydrate reservoir probably contains 2 — 10 times the currently known reserves of conventional natural gas, as of 2013 [update].

Hydrates normally exclude the salt in the pore fluid from which it forms, thus they exhibit high electric resistivity just like ice, and sediments containing hydrates have a higher resistivity compared to sediments without gas hydrates (Judge [6Hydrates normally exclude the salt in the pore fluid from which it forms, thus they exhibit high electric resistivity just like ice, and sediments containing hydrates have a higher resistivity compared to sediments without gas hydrates (Judge [6hydrates have a higher resistivity compared to sediments without gas hydrates (Judge [6hydrates (Judge [67]-RRB-.

On catastrophic methane degassing: Shakova and Semiletov have proposed a mechanism — the destabilisation of the permafrost cap overlying large methane hydrate deposits that contain a high proportion of free gas.

This matters because there is a huge amount of carbon currently locked up in permafrost, and the methane hydrates alone contain more carbon than all of Earth's proven reserves of coal, oil, and natural gas combined.
