Methane in the Martian Atmosphere
June 17, 2007 / Posted by: Shige Abe
Scientists from NAI’s IPTAI Team have a paper out in Geophysical Research Letters detailing a new mechanism for recent methane release on Mars. Their results show that increasing salinity can cause destabilization of subsurface methane hydrates, and that active thermal or pressure fluctuations are not required to account for the presence of methane in the atmosphere.
