Potential methane reservoirs beneath Antarctica
http://www.nature.com/nature/journal/v488/n7413/full/nature11374.html
Editor's summary
Antarctic methane predicted
The ice-covered parts of Antarctica are known to be a reservoir of metabolically active microbial cells and organic carbon, but the potential for microorganisms to support the degradation of organic carbon to methane beneath the ice has not yet been evaluated. In this paper, Jemma Wadham and colleagues numerically simulate the accumulation of methane in Antarctic sedimentary basins. Their findings suggest that the Antarctic Ice Sheet may be a neglected but important component of the global methane inventory that could act as a positive feedback on global climate change during episodes of ice-sheet collapse.
