Advanced knowledge and new technologies in gas hydrate research

Gas hydrates are considered a potential source of energy. Over the past 10 years, the Submarine Gas Hydrate Deposits (SUGAR) project has significantly expanded the basic knowledge of gas hydrates and resulted in the development ...

Stable gas hydrates can trigger landslides

Like avalanches onshore,many processes cause submarine landslides. One very widespread assumption is that they are associated with dissociating gas hydrates in the seafloor. However, scientists at GEOMAR Helmholtz Centre ...

Why did gas hydrates melt at the end of the last ice age?

Methane hydrates, also known as "burning ice," occur at all ocean margins. The compound of gas and water occurs in the seafloor and it is only stable under relatively high pressures and low temperatures. If the pressure is ...

Recurring martian streaks: flowing sand, not water?

Dark features on Mars previously considered evidence for subsurface flowing of water are interpreted by new research as granular flows, where grains of sand and dust slip downhill to make dark streaks, rather than the ground ...

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 ...
