Methane produced by microorganisms in subsurface environments may account for a large fraction of global natural gas reserves. To understand how microbial methane is produced during sediment burial history, we examined methane-bearing aquifers in which temperature and salinity increase with depth. Geochemical and microbiological analyses showed that microbial methane is produced at depth, where microbial activity is stimulated by the increased temperature, and subsequently migrates upwards.
