Study finds hydrate gun hypothesis unlikely

Clathrate (hydrate) gun hypothesis stirred quite the controversy when it was posed in 2003. It stated that methane hydrates—frozen water cages containing methane gas found below the ocean floor—can melt due to increasing ...

China, Japan extract combustible ice from seafloor

Commercial development of the globe's huge reserves of a frozen fossil fuel known as "combustible ice" has moved closer to reality after Japan and China successfully extracted the material from the seafloor off their coastlines.

Arctic Ocean methane does not reach the atmosphere

250 methane flares release the climate gas methane from the seabed and into the Arctic Ocean. During the summer months this leads to an increased methane concentration in the ocean. But surprisingly, very little of the climate ...

Retreat of the ice followed by millennia of methane release

Scientists have calculated that the present day ice sheets keep vast amounts of climate gas methane in check. Ice sheets are heavy and cold, providing pressure and temperatures that contain methane in form of ice-like substance ...

Ice streams can be slowed down by gas hydrates

A sticky spot the size of a small island once slowed down a large ice stream. It was comprised of gas hydrates according to a new study in Nature Geoscience.

Type of ice reveals the age of comets

The ice buried inside comet 67P/ Churyumov-Gerasimenko is mainly found in crystalline form, which implies that it originated in the protosolar nebula and is therefore the same age as the Solar System. This discovery was made ...
