Microbial Life in the Deep Subsurface Aquifer Illuminated by Metagenomics [PDF]
Frontiers in Microbiology, 2020 To get insights into microbial diversity and biogeochemical processes in the terrestrial deep subsurface aquifer, we sequenced the metagenome of artesian water collected at a 2.8 km deep oil exploration borehole 5P in Western Siberia, Russia. We obtained

Coupled C, H, N, S and Fe biogeochemical cycles operating in the continental deep subsurface of the Iberian Pyrite Belt. [PDF]
Environ Microbiol, 2023 Microbial activity is a major contributor to the biogeochemical cycles that make up the life support system of planet Earth. A 613 m deep geomicrobiological perforation and a systematic multi‐analytical characterization revealed an unexpected diversity ...

Subduction hides high-pressure sources of energy that may feed the deep subsurface biosphere [PDF]
Nature Communications, 2020 Geological sources of H2 and abiotic CH4 have had a critical role in the evolution of life and sustainability of the deep subsurface biosphere, yet the origins of these sources remain largely unconstrained.

A global perspective on bacterial diversity in the terrestrial deep subsurface. [PDF]
Microbiology (Reading), 2023 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.

Geological activity shapes the microbiome in deep-subsurface aquifers by advection. [PDF]
Proc Natl Acad Sci U S A, 2022 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 life. However,

Evolutionary stasis of a deep subsurface microbial lineage. [PDF]
ISME J, 2021 Sulfate-reducing bacteria Candidatus Desulforudis audaxviator (CDA) were originally discovered in deep fracture fluids accessed via South African gold mines and have since been found in geographically widespread deep subsurface locations.

The Mystery of Piezophiles: Understudied Microorganisms from the Deep, Dark Subsurface
Microorganisms, 2023 Microorganisms that can withstand high pressure within an environment are termed piezophiles. These organisms are considered extremophiles and inhabit the deep marine or terrestrial subsurface.

Maximum Credible Earthquake Ground Motions with Focus on Site Amplification due to Deep Subsurface
Engineering, Technology & Applied Science Research, 2021 Since an Earthquake Ground Motion (EGM) is amplified from the propagation through the ground, different models are required for each ground type in the seismic design of structures.

First look by the Yutu-2 rover at the deep subsurface structure at the lunar farside. [PDF]
Nat Commun, 2020 The unequal distribution of volcanic products between the Earth-facing lunar side and the farside is the result of a complex thermal history. To help unravel the dichotomy, for the first time a lunar landing mission (Chang’e-4, CE-4) has targeted the ...
