More Arctic Methane Bubbles into Atmosphere
Scientists are continually working to improve estimates of just how much methane, a potent greenhouse gas, is being emitted from the Arctic.
A new study led by researcher Natalia Shakhova of the University of Alaska, Fairbanks, and the Russian Academy of Sciences’ Far Eastern Branch reports that methane releases from one part of the Arctic Ocean are more than twice what scientists previously thought.
Shakhova and her colleagues investigated releases of methane from permafrost underneath a shallow part of the Arctic Ocean called the East Siberian Arctic Shelf, which sits in the ocean north of Siberia and east of the Lena River Delta.
