New ecosystems in the deep subsurface follow the flow of water driven by geological activity. [PDF]
Sci Rep, 2019 Eukarya have been discovered in the deep subsurface at several locations in South Africa, but how organisms reach the subsurface remains unknown. We studied river-subsurface fissure water systems and identified Eukarya from a river that are genetically ...

Multi-Regional Study on the Microbial Community Structure, Core Microbiome and Functional Characteristics in Deep Fracture Waters [PDF]
MicroorganismsThe deep terrestrial subsurface is the largest reservoir of Earth’s freshwater resources as well as the largest habitat for prokaryotic life. However, the deep-subsurface microbiome, especially its spatial distribution across countries/continents, is ...

Artificial subsurface lithoautotrophic microbial ecosystems and gas storage in deep subsurface. [PDF]
FEMS Microbiol EcolAbstract Over the next few years, it is planned to convert all or part of the underground gas storage (UGS) facilities used for natural gas (salt caverns, depleted hydrocarbon reservoirs, and deep aquifers) into underground dihydrogen (H2) storage reservoirs.

Progress and prospect of surface-wave imaging techniques in near-surface applications
地球与行星物理论评, 2022 Elastic properties of near-surface materials and their effects on seismic wave propagation are of fundamental interest in groundwater, engineering, and environmental studies. Shear-wave velocity is used to determine 'stiffness', one of the key properties

Advances in Defining Ecosystem Functions of the Terrestrial Subsurface Biosphere
Frontiers in Microbiology, 2022 The subsurface is one of the last remaining ‘uncharted territories’ of Earth and is now accepted as a biosphere in its own right, at least as critical to Earth systems as the surface biosphere.

A Comparative Study on the Dynamic Tensile Strength Evaluation Method of Rock Materials
Shock and Vibration, 2023 The representative calculation methods of dynamic tensile strength applied to the spalling test are comparatively reviewed in the same experimental cases. The results are compared with those of the ISRM suggested dynamic BD method.

Biological Production of H2 , CH4 , and CO2 in the Deep Subsurface of the Iberian Pyrite Belt.
Environmental Microbiology, 2021 Most of the terrestrial deep subsurfaces are oligotrophic environments in which some gases, mainly H2 , CH4 , and CO2 , play an important role as energy and/or carbon sources.
