Microbial Life in Deep Terrestrial Subsurfaces
BioScience, 1989In 1985 the US Department of Energy (DOE) established a research program called Microbiology of the Deep Subsurface, which focuses on detecting microorganisms at greater depths, establishing fundamental scientific information, including their ecology, and exploring their potential use in clean-up of contaminated deep terrestrial sediments and ...

Microbial communities in the deep subsurface
Hydrogeology Journal, 2000The diversity of microbial populations and microbial communities within the earth's subsurface is summarized in this review. Scientists are currently exploring the subsurface and addressing questions of microbial diversity, the interactions among microorganisms, and mechanisms for maintenance of subsurface microbial communities. Heterotrophic anaerobic

New Horizons for Deep Subsurface Microbiology
Microbe Magazine, 2009The U.S. Department of Energy (DOE) launched the modern era of subsurface microbiology at its Savannah River Plant (SRP) in South Carolina in 1986. Those first efforts, involving three 200-m-deep wells along with procedures to monitor for drilling-related contaminants, uncovered abundant and diverse microbial communities in subsurface aquifers (Fig. 1).

A deep subsurface ice probe for Europa
2017 IEEE Aerospace Conference, 2017This paper describes work on a concept for a probe that would be capable of km-scale deep subsurface ice penetration on Europa or other Ocean World. Penetrating deep into or through the ice cap over the liquid ocean is the best way to establish if life has evolved there.

Microbial Electron Transport in the Deep Subsurface
2017The deep ocean may be one of the largest microbial habitats on the planet. Hence, high hydrostatic pressure is a feature of microbial life. We know very little about the deep biosphere because simulating deep ocean conditions in the laboratory whilst simultaneously monitoring microbial processes is difficult.

Electrical Methods for Deep Subsurface Exploration
IEEE Transactions on Geoscience Electronics, 1967A 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
2014This 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.
