Subglacial lakes are repositories of ancient climate conditions, provide habitats for life and
modulate ice flow, basal hydrology, biogeochemical fluxes and geomorphic activity. In this …

This review of material relevant to the Conference on Biosignature Preservation and
Detection in Mars Analog Environments summarizes the meeting materials and discussions …

Microbial abundance and diversity in deep subsurface environments is dependent upon the
availability of energy and carbon. However, supplies of oxidants and reductants capable of …

The terrestrial subsurface hosts microbial communities that, collectively, are predicted to
comprise as many microbial cells as global surface soils. Although initially thought to be …

Terrestrial and aquatic ecosystems have specific carbon fingerprints and sequestration
potential, due to the intrinsic properties of the organic matter (OM), mineral content …

Geothermal heat flow (GHF) is an elusive physical property, yet it can reveal past and
present plate tectonic processes. In Antarctica, GHF has further consequences in predicting …

Scientific deep drilling at Koyna, western India provides a unique opportunity to explore
microbial life within deep biosphere hosted by~ 65 Myr old Deccan basalt and Archaean …

Studies of antibiotic-resistant bacteria (ARB) have mainly originated from anthropic-
influenced environments, with limited information from pristine environments. Remote cold …

Continental subsurface environments can present significant energetic challenges to the
resident microorganisms. While these environments are geologically diverse, potentially …

Earth's subsurface is often isolated from phototrophic energy sources and characterized by
chemotrophic modes of life. These environments are often oligotrophic and limited in …
