'Widespread methane leakage coming hundreds of vents off East Coast
2014-08-25 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: Methane bubbles flow in small streams out of the sediment on an area of sea floor of Virginia north of Washington Canyon. Quill worms, anemones and patches of microbial mat can be seen in and along the periphery of the seepage area. (NOAA Okeanos Explorer Program, 2013) Of all the global warming gasses, methane is one of the very worst. Pound for pound, the Environmental Protection Agency says its effect on global warming is 20 times greater than that of carbon dioxide. And though its lifetime...

Over 500 Methane Vents Found on Atlantic Ocean Floor Off US East Coast
2014-08-25 12:06:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: The Atlantic Ocean floor off the U.S. East Coast has over 500 methane vents, a new study has found. The study, conducted by researchers at the Mississippi State University, shows that large amount of methane leaking from the seafloor might be contributing to global warming. "It is the first time we have seen this level of seepage outside the Arctic that is not associated with features like oil or gas reservoirs or active tectonic margins," said Prof Adam Skarke from Mississippi State University,...
Methane Is Discovered Seeping From Seafloor Off East Coast, Scientists Say

New York Times: Scientists have discovered methane gas bubbling from the seafloor in an unexpected place: off the East Coast of the United States where the continental shelf meets the deeper Atlantic Ocean. The methane is emanating from at least 570 locations, called seeps, from near Cape Hatteras, N.C., to the Georges Bank southeast of Nantucket, Mass. While the seepage is widespread, the researchers estimated that the amount of gas was tiny compared with the amount released from all sources each year. In a paper...

Methane vents bubble up off US coast
2014-08-24 19:04:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: Researchers say they have found more than 500 bubbling methane vents on the seafloor off the US east coast. The unexpected discovery indicates there are large volumes of the gas contained in a type of sludgy ice called methane hydrate. There are concerns that these new seeps could be making a hitherto unnoticed contribution to global warming. The scientists say there could be about 30,000 of these hidden methane vents worldwide. Previous surveys along the Atlantic seaboard have shown...
Hundreds of Methane Plumes Erupting Along East Coast

LiveScience: In an unexpected discovery, hundreds of gas plumes bubbling up from the seafloor were spotted during a sweeping survey of the U.S. Atlantic Coast. Even though ocean explorers have yet to test the gas, the bubbles are almost certainly methane, researchers report today (Aug. 24) in the journal Nature Geoscience. "We don't know of any explanation that fits as well as methane," said lead study author Adam Skarke, a geologist at Mississippi State University in Mississippi State. Surprising seeps...
