Abstract: ABSTRACT Ultramafic rocks are hypothesized to support a subseafloor hydrogen-driven biosphere because of extensive production of bioavailable energy sources like H2 or CH4 from fluid-rock interactions. Hence, the apparent lack of microbial remains in subseafloor… read more here.

DOI: 10.1126/sciadv.aba0697
Abstract: The global subseafloor biosphere subsists under extreme and widespread energy limitation. Microbial cells buried in subseafloor sediments comprise a substantial portion of Earth’s biosphere and control global biogeochemical cycles; however, the rate at which they… read more here.

DOI: 10.1128/mbio.00354-22
Abstract: The cold, oxic subseafloor is an understudied habitat that is difficult to access, yet important to global biogeochemical cycles and starkly different compared to microbial habitats on the surface of the Earth. Our understanding of… read more here.
