DOI: 10.1029/2019gl082394
Abstract: Barometric pumping caused by atmospheric pressure fluctuations contributes to the motion of gases in the vadose zone. While the resulting gas transport is often negligible in unfractured porous rocks, rates of transport in fractured media… read more here.

DOI: 10.1073/pnas.2113985119
Abstract: Significance Sheltered from radiation and asteroid strikes in Earth’s early history and home to a significant portion of today’s prokaryotic biomass, the deep subsurface could hold keys to understanding the early and continuing evolution of… read more here.

DOI: 10.1099/mic.0.001172
Abstract: While recent efforts to catalogue Earth’s microbial diversity have focused upon surface and marine habitats, 12–20 % of Earth’s biomass is suggested to exist in the terrestrial deep subsurface, compared to ~1.8 % in the deep subseafloor.… read more here.

DOI: 10.1128/aem.00018-19
Abstract: The hydraulic fracturing of deep-shale formations for hydrocarbon recovery accounts for approximately 60% of U.S. natural gas production. Microbial activity associated with this process is generally considered deleterious due to issues associated with sulfide production,… read more here.

DOI: 10.3389/fmicb.2022.826048
Abstract: The deep terrestrial biosphere hosts vast sessile rock surface communities and biofilms, but thus far, mostly planktic communities have been studied. We enriched deep subsurface microbial communities on mica schist in microcosms containing bedrock groundwater… read more here.

DOI: 10.3389/fmicb.2023.1054084
Abstract: Microbial life in the deep subsurface occupies rock surfaces as attached communities and biofilms. Previously, epilithic Fennoscandian deep subsurface bacterial communities were shown to host genetic potential, especially for heterotrophy and sulfur cycling. Acetate, methane,… read more here.
