PhysOrg: Arctic seabed methane stores destabilizing, venting

Arctic seabed methane stores destabilizing, venting
PhysOrg Earth Sciences - 2010 March 04
A section of the Arctic Ocean seafloor that holds vast stores of frozen methane is showing signs of instability and widespread venting of the powerful greenhouse gas, according to the findings of an international research team led by University of Alaska Fairbanks scientists Natalia Shakhova and Igor Semiletov.

The research results, published in the March 5 edition of the journal Science, show that the permafrost under the East Siberian Arctic Shelf, long thought to be an impermeable barrier sealing in methane, is perforated and is leaking large amounts of methane into the atmosphere. Release of even a fraction of the methane stored in the shelf could trigger abrupt climate warming.

If they could develop a cost effective method of capture and storage, it could be utilized as a replacement for or enhancement to current natural gas stores for energy. With the added plus of not being directly released onto atmosphere.
