Microbial origin of excess methane in glacial ice and implications for life on Mars, PNAS

“Equating the loss rate of methane recently discovered in the Martian atmosphere to the production rate by possible methanogens, we estimate that a possible Martian habitat would be at a temperature of 0C and that the concentration, if uniformly distributed in a 10-m-thick layer, would be 1 cell per ml.”
