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

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...

Numerous methane leaks found on Atlantic sea floor

ScienceMag: And up through the ground came a bubbling greenhouse gas. Researchers have discovered 570 plumes of methane percolating up from the sea floor off the eastern coast of the United States, a surprisingly high number of seeps in a relatively quiescent part of the ocean. The seeps suggest that methanes contribution to climate change has been underestimated in some models. And because most of the seeps lie at depths where small changes in temperature could be releasing the methane, it is possible that...

Climate change and the methane crisis: Q & A with Harold Hensel
2014-08-23 16:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Examiner: With climate change rearing its ugly head with extreme weather disasters pounding the globe, some people have been connecting the dots to the horrifying conclusion that there is yet another catastrophe underway with implications far exceeding what most of us could ever dream of: an unfolding methane crisis of epic proportions. Capable of causing a planetary extinction, record high amounts of methane are insidiously being released into the oceans and going into our atmosphere. Methane, a colorless...
