Modelling of deep subsurface for geohazard risk assessment

2021
Exploitation of subsurface natural resources, and subsurface storage of energy residues, may cause subsurface and surface deformation and damage to property. Deformation is generally difficult to assess and prove, although economical, environmental and societal interests are huge in terms of strain on granting concessions, (potential) damage claims etc.

Starvation-survival of deep subsurface isolates

Current Microbiology, 1993
Six deep, subsurface endolithic isolates were subjected to starvation conditions for up to 100 days in artificial pore water, formulated to mimic in situ geochemical conditions in the nearly saturated rock. Most isolates demonstrated the typical starvation-survival curve for chemoheterotrophic bacteria, and all became miniaturized during starvation ...

Deep-sea smokers: Windows to a subsurface biosphere?

Geochimica et Cosmochimica Acta, 1993
Since the discovery of hyperthermophilic microbial activity in hydrothermal fluids recovered from "smoker" vents on the East Pacific Rise, the widely accepted upper temperature limit for life (based on pure culture data) has risen from below the boiling point of water at atmospheric pressure to approximately 115 degrees C.

Electrical Methods for Deep Subsurface Exploration

IEEE Transactions on Geoscience Electronics, 1967
A theoretical study has been made of the transmission of electrical signals through the earth in order to devise the most promising methods for determining the electrical resistance of deeplying formations. It was found that the most effective technique is one which apparently has not been previously proposed.

Spatial Segregation: The Deep Subsurface Story

2014
This chapter focuses on the physical and chemical characteristics of the terrestrial subsurface that are most likely to influence microbial evolution, with emphasis on the spatial segregation issue, and suggests possible directions for future research.

The deep subsurface biosphere is alive and well

Trends in Microbiology, 2005
For the first time, metabolically active bacterial cells have recently been quantified in deep marine sediments. In contrast to previous total cell counts that do not differentiate between active cells and inactive or dormant cells, these quantifications using oligonucleotide hybridization probes target active cells and their ribosomal (r)RNA.
