Scientists have identified thousands of sites in the Arctic where methane that has been stored for many millennia is bubbling into the atmosphere. The methane has been trapped by ice, but is able to escape as the ice melts. Writing in the journal Nature Geoscience, the researchers say this ancient gas could have a significant impact on climate change. Methane is the second most important greenhouse gas after CO2 and levels are rising after a few years of stability. There are many sources of the gas around the world, some natural and some man-made, such as landfill waste disposal sites...

Microbes possibly feeding on the remains of an ancient forest may be generating billions of tons of methane deep beneath Antarctic ice, a new study suggests. The amount of this greenhouse gas — which would exist in the form of a frozen latticelike substance called methane hydrate — lurking beneath the ice sheet rivals that stored in the world's oceans, the researchers said. If the ice sheet collapses, the greenhouse gas could be released into the atmosphere and dramatically worsen global warming, researchers warn in a study published in the Aug. 30 issue of the journal Nature. "There could be...

An international team of researchers has discovered a methane-consuming microorganism that lives in extremely acidic conditions. The bacterium could one day be used to reduce methane gas emissions from landfills. It could also help to cut methane emissions from geothermal power stations. Aerobic methanotrophic bacteria (methanotrophs) consume methane diffusing away from methane-producing zones of soil and sediment. Some environments with active methane cycles—such as marshes and peat bogs—are very acidic; however, no cultured methanotroph grows optimally below pH 5. By contrast, the new bacterium is extremely acidophilic, and grows optimally at pH 2.0-2.5. Unlike known methanotrophs, which belong to the...

A new study demonstrates how high hydrocarbons could be formed from methane deep within the Earth, aside from the compression and heating of ancient animal remains over the eons. Fused-methane oil would be far less common than your typical petroleum, of course, but the study shows abiogenic hydrocarbons could conceivably occur in some of the planet’s high-pressure and high-temperature zones. Scientists at Lawrence Livermore National Laboratory used supercomputers to simulate what would happen to carbon and hydrogen atoms buried 40 to 95 miles beneath the Earth’s crust, where they would be subjected to prodigious pressures and temperatures. They found at...

About half of the oil in the ocean bubbles up naturally from the seafloor, with Earth giving it up freely like it was of no value. Likewise, NASA satellites collect thousands of images and 1.5 terrabytes of data every year, but some of it gets passed over because no one thinks there is a use for it.

Sole member of world's first single-species ecosystem depends on rocks and radioactivity for life. The rod-shaped D. audaxviator was recovered from thousands of litres of water collected deep in the Mponeng Mine in South Africa.Greg Wanger, J. Craig Venter Institute / Gordon Southam, University of Western Ontario Nestled kilometres down in the hot, dark vaults of Earth's crust, scientists have discovered a remarkably lonely bacterium species. The rod-shaped bacterium, Candidatus Desulforudis audaxviator, lives independently of any other organism in a part of the Mponeng gold mine near Johannesburg, South Africa, some 2.8 kilometres beneath Earth's surface. There, water flows from...

Desulforudis audaxviator is an organism that lives independently in total darkness and at high temperature by reducing sulfate and fixing carbon and nitrogen from its environment, deep within the Earth. It constitutes the first known single-species ecosystem.

There the rod-shaped bacterium Desulforudis audaxviator exists in complete isolation, total darkness, a lack of oxygen, and 60-degree-Celsius heat...

At 30,000 feet down, where were the dinosaurs? Posted: November 29, 20051:00 a.m. Eastern © 2005 WorldNetDaily.com Developments in deep-drilling for natural gas present serious challenges to those who still maintain "Fossil-Fuel" theories as to the origin of complex hydrocarbon fuels. The Western world's record for deep-well natural-gas exploration and production is held by the GHK Company in Oklahoma. From 1972 through 1974, the company engineered and drilled two Oklahoma natural-gas commercial wells at depths greater than 30,000 feet (approximately 5.7 miles) – the No. 1-27 Bertha Rogers well (total depth 31,441 feet) and the No. 1-28 E.R. Baden well, both located...
