STARKVILLE, Miss., Aug. 26, 2014 /PRNewswire-USNewswire/ -- New questions about geology, oceanography and seafloor ecosystems are being raised because of research by a Mississippi State University geologist. Lead author Adam Skarke, assistant professor of geosciences at MSU, worked with researchers from the U.S. Geological Survey (USGS) and other institutions on a scientific team that discovered methane seeps in unlikely places along the seafloor on the northern part of the U.S....

Global Warming Not Primary Cause Of Svalbard-Area Methane Release
2014-01-03 07:47:38

redOrbit Staff & Wire Reports - Your Universe Online Natural processes, not global warming, are primarily to blame for the dissolution of the fragile, ice-like solid fuel substances known as methane hydrates, according to new research published online Thursday in the journal Science. Methane hydrates, which are composed of water and methane, are only stable in high pressure and low temperature conditions, the study authors explained. In some areas, such as in the North Atlantic off...

Arctic Seafloor Releases Double Previous Estimates Of Methane
2013-11-26 07:19:53

University of Alaska Fairbanks The seafloor off the coast of Northern Siberia is releasing more than twice the amount of methane as previously estimated, according to new research results published in the Nov. 24 edition of the journal Nature Geoscience. The East Siberian Arctic Shelf is venting at least 17 teragrams of the methane into the atmosphere each year. A teragram is equal to 1 million tons. “It is now on par with the methane being released from the arctic tundra, which is...

Dwarfism In Mammals Also Occurred During Second Warming Period
2013-11-03 05:03:03

redOrbit Staff & Wire Reports - Your Universe Online While scientists have known for several years that some mammals became smaller during a period of warming known as the Paleocene-Eocene Thermal Maximum (PETM), researchers from the University of Michigan have found a second instance of mammalian “dwarfing” attributable to increasing temperatures. During the PETM, which occurred approximately 55 million years ago, mammals such as primates and groups that include deer and horses...

Worm Causing Methane Release Ocean Bed
2013-08-13 08:36:26

April Flowers for redOrbit.com - Your Universe Online A super-charged methane seep has been discovered in the ocean off the coast of New Zealand. The seep has created its own unique food web, resulting in elevated amounts of methane escaping from the ocean floor into the water column, according to scientists at Oregon State University. Methane is a greenhouse gas 23 times more potent than carbon dioxide at warming our atmosphere. Most of the methane in the seep is likely consumed by...

Methane Release From Earthquakes Feeds Global Warming

Michael Harper for redOrbit.com - Your Universe Online In 1945 an 8.1 magnitude earthquake hit the northern Arabian Sea which released 7.4 million cubic meters of methane into the ocean and atmosphere. Now a team of scientists from the MARUM Institute at the University of Bremen, the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, and the ETH Zurich have concluded a study on this earthquake and believe similar temblors are also adding to the release of...

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...

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
2012-08-22 14:31:40

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...
