Man-made Methane Emissions Traced To Roman Times
2012-10-04 05:52:22

April Flowers for redOrbit.com - Your Universe Online Analysis of the Greenland ice sheet is allowing scientists to trace the emissions of the greenhouse gas methane back thousands of years. A research team, led by the Niels Bohr Institute, has determined how much methane originates from natural sources and how much is due to human activity using special analytical methods. The resulting data can be dated back to Roman times and up to the present. More than half the emissions today are...

Microbes Produced Oxygen Well Before Great Oxidation Event

Brett Smith for redOrbit.com - Your Universe Online Life on earth began in the oceans, but it would eventually spread to land and a new study suggests that land-dwelling bacteria could have covered large swaths of territory about 2.7 billion years ago, despite a thin ozone layer that would have offered little protection against the sun´s ultraviolet radiation. According to astrobiologists at the University of Washington, these earliest microbes produced oxygen and broke down...

Expedition to the Greenland Sea with Surprising Results Marine scientists from Kiel, together with colleagues from Bremen, Great Britain, Switzerland and Norway, spent four and a half weeks examining methane emanation from the sea bed off the coast of Spitsbergen with the German research vessel MARIA S. MERIAN. There they gained a very differentiated picture: Several of the gas outlets have been active for hundreds of years. Frequent storms and sub-zero temperatures — nature drove...

Mechanism Discovered in Deep Ocean Production Of Methane
2012-08-31 13:17:05

Brett Smith for redOrbit.com - Your Universe Online While searching for new and more effective antibiotics, a team of biologists and chemists has stumbled upon the mechanism responsible for the deep ocean production of methane, a greenhouse gas that drives climate change. Researchers from the University of Illinois and the University of Washington began their studies examining microbes´ production of phosphonates that these tiny creatures use to disrupt bacteria and other...

Methane Reservoir Beneath Antarctic Ice Sheet
2012-08-30 08:32:12

April Flowers for redOrbit.com - Your Universe Online A recent study of the Antarctic Ice Sheet suggests that it could be a largely overlooked source of the potent greenhouse gas methane. An international team of scientists from the University of Bristol, the University of California, Santa Cruz, the University of Alberta, Edmonton, and the University of Utrecht, demonstrate that old organic matter in sedimentary basins located beneath the Antarctic Ice Sheet may have been converted to...

Mystery About Sky-high Methane Closer To Being Solved

Commercial natural gas was likely major factor in late-20th century stabilization Increased capture of natural gas from oil fields probably accounts for up to 70 percent of the dramatic leveling off seen in atmospheric methane at the end of the 20th century, according to new UC Irvine research being published Thursday, Aug. 23, in the journal Nature. “We can now say with confidence that, based on our data, the trend is largely a result of changes in fossil fuel use,” said...

Examining gas outlets off the coast of Spitsbergen with the submersible JAGO West of Spitsbergen methane gas is effervescing out of the seabed. Is this an indication that methane hydrates in the seabed are dissolving due to rising temperatures? And what would the effects be? An expedition with the German research vessel MARIA S. MERIAN and the submersible JAGO lead by GEOMAR | Helmholtz Centre for Ocean Research Kiel hopes to help answer these questions. The expedition begins today in...

Uranus' moon Umbriel -- Umbriel is a moon of Uranus discovered in 1851 by William Lassell. It was named after the 'dusky melancholy sprite' in Alexander Pope's The Rape of the Lock. Umbriel's surface is the darkest of the Uranian moons, and it is also the least geologically active. It is mostly composed of water ice, with the balance made up of silicate rock and methane ice. Most of its methane ice is on its surface. ----- Discovery Discovered by William Lassell...

Uranus' moon Ariel -- Ariel is a moon of Uranus discovered in 1851 by William Lassell. Its composition is roughly 50% water ice, 30% silicate rock, and 20% methane ice, and it appears to have regions of fresh frost in places. Largely devoid of impact craters, Ariel appears to have undergone a period of intense geological activity that has produced a huge network of fault canyons and liquid water outflows over its surface. ----- Discovery Discovered by William Lassell...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
