Recent orbital and rover missions to Mars have turned up ample evidence of clays and other hydrated minerals formed when rocks are altered by the presence of water. Most of that alteration is thought to have happened during ...

Methane hydrates are a kind of ice that contains methane, and that form at certain depths under the sea or buried in permafrost. They can also form in pipelines that transport oil and gas, leading to clogging. Yet methane ...

Warming ocean temperatures a third of a mile below the surface, in a dark ocean in areas with little marine life, might attract scant attention. But this is precisely the depth where frozen pockets of methane 'ice' transition ...

Like the carbon dioxide in a fizzing glass of soda, most bubbles of gas in a liquid don't last long. But nanobubbles persist. These bubbles are thousands of times smaller than the tip of a pencil lead—so small they are ...

Large amounts of methane - whether as free gas or as solid gas hydrates - can be found in the sea floor along the ocean shores. When the hydrates dissolve or when the gas finds pathways in the sea floor to ascend, the methane ...

Research led by a University of New Hampshire professor has identified a new source of methane for gas hydrates—ice-like substances found in sediment that trap methane within the crystal structure of frozen water—in the ...

Off the West Coast of the United States, methane gas is trapped in frozen layers below the seafloor. New research from the University of Washington shows that water at intermediate depths is warming enough to cause these ...

(Phys.org) —A decade of research by Rice University scientists has produced a two-dimensional model to prove how gas hydrate, the "ice that burns," is formed under the ocean floor.

Methane hydrates are fragile. At the sea floor the ice-like solid fuel composed of water and methane is only stable at high pressure and low temperature. In some areas, for instance in the North Atlantic off the coast of ...

On the continental margins, where the seafloor drops hundreds of meters below the water's surface, low temperatures and high pressure lock methane inside ice crystals. Called methane hydrates, these crystals are a potential ...
