Microbial activity in the marine deep biosphere: Progress and prospects
Frontiers in Microbiology, 2013 The vast marine deep biosphere consists of microbial habitats within sediment, pore waters, upper basaltic crust and the fluids that circulate throughout it.

Subsurface microbiological heterogeneity: current knowledge, descriptive approaches and applications [PDF]
FEMS Microbiology Reviews, 1997 Improved understanding of the spatial and temporal distribution of microbiological properties and processes is critical due to the relative difficulty and high cost of obtaining large numbers of subsurface samples. Quantification of spatial patterns in subsurface environments is important because it is well known that geologic, hydrologic and ...

A cell extraction method for oily sediments
Frontiers in Microbiology, 2011 Hydrocarbons can be found in many different habitats and represent an important carbon source for microbes. As fossil fuels, they are also an important economical resource, through natural seepage or accidental release they can also be major pollutants ...

There's Plenty of Room at the Bottom: Low Radiation as a Biological Extreme
Frontiers in Astronomy and Space Sciences, 2020 The effects of high radiation as a biological extreme have historically been, and continue to be, extensively researched in the fields of radiation biology and astrobiology.

Microbial diversity gradients in the geothermal mud volcano underlying the hypersaline Urania Basin
Frontiers in Microbiology, 2022 Mud volcanoes transport deep fluidized sediment and their microbial communities and thus provide a window into the deep biosphere. However, mud volcanoes are commonly sampled at the surface and not probed at greater depths, with the consequence that ...

Prokaryotic communities from a lava tube cave in La Palma Island (Spain) are involved in the biogeochemical cycle of major elements [PDF]
PeerJ, 2021 Lava caves differ from karstic caves in their genesis and mineral composition. Subsurface microbiology of lava tube caves in Canary Islands, a volcanic archipelago in the Atlantic Ocean, is largely unknown.

The DynaDeep observatory – a unique approach to study high-energy subterranean estuaries
Frontiers in Marine Science, 2023 Subterranean estuaries are connective zones between inland aquifers and the open sea where terrestrial freshwater and circulating seawater mix and undergo major biogeochemical changes.
