N2 - Microbial populations inhabit deeply buried marine sediments, but the extent of this vast ecosystem is poorly constrained. Here we provide evidence for the existence of microbial communities in sediment associated with lignite coalbeds at ~1.9 to 2.5 km below the seafloor in the Pacific Ocean off Japan. Microbial methanogenesis is indicated by isotopic data of methane and carbon dioxide, methanogenic biomarkers, cultivation and gas composition results. Rigorous protocols aimed at minimizing and correcting for sample contamination resulted in indigenous biomass estimates as low as ~10 cells cm 3 or less in the ~40 to 60°C warm sediments, while coal-bearing sediment layers had elevated cell concentrations. This ultra-deep microbial community is taxonomically distinct from typical shallower deep-biosphere communities found at this and other marine locations.
