Shrinking majority of the deep biosphere. [PDF]
Proc Natl Acad Sci U S A, 2012 Living microorganisms were first discovered in sediment cores from scientific ocean drilling in the late 1980s when microbiologists observed and counted DNA-stained microbial cells under the microscope. During the following decade, new observations were made from drill sites in the Atlantic and Pacific Oceans and the Mediterranean Sea (1, 2).

Tracking the Deep Biosphere through Time
Geosciences, 2020 The oceanic and continental lithosphere constitutes Earth’s largest microbial habitat, yet it is scarcely investigated and not well understood. The physical and chemical properties here are distinctly different from the overlaying soils and the ...

Prospects for the study of evolution in the deep biosphere. [PDF]
Front Microbiol, 2011 Since the days of Darwin, scientists have used the framework of the theory of evolution to explore the interconnectedness of life on Earth and adaptation of organisms to the ever-changing environment. The advent of molecular biology has advanced and accelerated the study of evolution by allowing direct examination of the genetic material that ...

The role of anaerobic fungi in fundamental biogeochemical cycles in the deep biosphere [PDF]
Fungal Biology Reviews, 2018 A major part of the biologic activity on Earth is hidden underneath our feet in an environment coined the deep biosphere which stretches several kilometers down into the bedrock.

Life in the deep sub-seafloor biosphere [PDF]
Energy Exploration & Exploitation, 2003 There is abundant evidence that prokaryotic cells live deep beneath the sea floor. Pore water chemical data from hundreds of DSDP and ODP sites document the occurrence of subsurface catabolic activity in sediments throughout most of the deep ocean ...

Genomic insights into a versatile deep-sea methanotroph constituting the rare biosphere of a Brazilian carbonate mound complex [PDF]
mSystemsRecent discoveries of aerobic methanotrophs in non-seep carbonate-rich environments in the deep sea suggest that these organisms may persist as part of the rare biosphere.

Fluids from the Oceanic Crust Support Microbial Activities within the Deep Biosphere
Geomicrobiology Journal, 2008 The importance of crustal fluid chemical composition in driving the marine deep subseafloor biosphere was examined in northeast Pacific ridge-flank sediments.
