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.

Methane seeps in the Canadian high Arctic

Cretaceous climate warming led to a significant methane release from the seafloor, indicating potential for similar destabilization of gas hydrates under modern global warming. A field campaign on the remote Ellef Ringnes ...

New research explains hydrophobicity

(Phys.org)—The hydrophobic effect is a fundamental aspect of biochemical processes. Hydrophilic, or water-loving, solutes tend to be miscible in water, while hydrophobic, or water-fearing, solutes tend to aggregate in such ...

Specialized life forms abound at Arctic methane seeps

Cold seeps are places where hydrocarbons, mostly methane, emanate from the sea floor. Unlike the hydrothermal vents, the fluids and bubbles are no hotter than the surrounding seawater, thus the name.

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 ...
