Methane-munching microbes living in the deep biosphere for 400 Million years

It is becoming more and more appreciated that a major part of the biologic activity is not going on at the ground surface, but...

Can melting of frozen methane explain rapid climate change 56 million...

New research, led by the University of Southampton, suggests that the release of methane from the seafloor was much slower than previously thought during...

Sediments control methane release to the ocean

Methane is stored under the sea floor, concentrated in form of hydrates, crystalline ice structures that stay stable under high pressure and in low...

Hydrothermal vents, methane seeps play enormous role in marine life, global...

The hydrothermal vents and methane seeps on the ocean floor that were once thought to be geologic and biological oddities are now emerging as...

Methane-producing microbes in California rocks

Deep in vents on the ocean floor, methane-producing microbes feed off chemical reactions between water and rock. Now evidence of this process has been...

UC geologists identify sources of methane, greenhouse gas, in Ohio, Colorado...

Researchers from the University of Cincinnati recently studied the sources of methane at three sites across the nation in order to better understand this...

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,...

Major source of methanol in the ocean identified

As one of the most abundant organic compounds on the planet, methanol occurs naturally in the environment as plants release it as they grow...

Tiny red crystals dramatically increase biogas production

UNSW Australia-led researchers have discovered a way to produce a tenfold increase in the amount of methane gas emitted by naturally occurring microbes living...

Clams help date duration of ancient methane seeps in the Arctic

Clams, mussels, scallops and oysters sound like delicious items on a restaurant menu. But bivalves such as these are much more than that: They...

Ice sheets may be hiding vast reservoirs of powerful greenhouse gas

The study indicates that under the frigid weight of Barents Sea Ice sheet, which covered northern Eurasia some 22 000 years ago, significant amounts...

Northern Methane: Largest natural sources of this potent greenhouse gas

Not all sources of methane emissions are man-made. A new study shows that northern freshwaters are critical emitters of this greenhouse gas. The findings from...

Methane feeds subsea ice mounds off Siberia

Pingos are spectacular landforms associated with permafrost in the Arctic. They are circular or elliptical formations protruding from the level ground of the tundra,...

New methane organisms discovered

Textbooks on methane-metabolising organisms might have to be rewritten after researchers in a University of Queensland-led international project today announced discovery of two new...

Bubble plumes off Washington, Oregon suggest warmer ocean may be releasing...

Warming ocean temperatures a third of a mile below the surface, in a dark ocean in areas with little marine life, might attract scant...

New study reveals mechanism regulating methane emissions in freshwater wetlands

The study, published in Nature Communications by Samantha Joye and colleagues, describes how high rates of anaerobic methane oxidation, a process once considered insignificant...

Exceptional view of deep Arctic Ocean methane seeps

Close to 30,000 high definition images of the deep Arctic Ocean floor were captured on a recent research cruise. This gives researchers insight into...

The invisible key to methane hydrates

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...

Ocean currents disturb methane-eating bacteria

Offshore the Svalbard archipelago, methane gas is seeping out of the seabed at the depths of several hundred meters. These cold seeps are a...

Ocean currents impact methane consumption

Large amounts of methane - whether as free gas or as solid gas hydrates - can be found in the sea floor along the...
