Metatranscriptomes Reveal That All Three Domains of Life Are Active but Are Dominated by Bacteria in the Fennoscandian Crystalline Granitic Continental Deep Biosphere [PDF]
The continental subsurface is suggested to contain a significant part of the earth’s total biomass. However, due to the difficulty of sampling, the deep subsurface is still one of the least understood ecosystems. Therefore, microorganisms inhabiting this

Shaping of the Present-Day Deep Biosphere at Chicxulub by the Impact Catastrophe That Ended the Cretaceous [PDF]
We report on the effect of the end-Cretaceous impact event on the present-day deep microbial biosphere at the impact site. IODP-ICDP Expedition 364 drilled into the peak ring of the Chicxulub crater, México, allowing us to investigate the microbial ...

In-situ detection of microbial life in the deep biosphere in igneous ocean crust [PDF]
The deep biosphere is a major frontier to science. Recent studies have shown the presence and activity of cells in deep marine sediments and in the continental deep biosphere. Volcanic lavas in the deep ocean subsurface, through which substantial fluid

Shrinking majority of the deep biosphere. [PDF]
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).

Genomic insights into a versatile deep-sea methanotroph constituting the rare biosphere of a Brazilian carbonate mound complex [PDF]
Recent 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.

Acetogenesis in the energy-starved deep biosphere – a paradox? [PDF]
Under anoxic conditions in sediments, acetogens are often thought to be outcompeted by microorganisms performing energetically more favorable metabolic pathways, such as sulfate reduction or methanogenesis. Recent evidence from deep subseafloor sediments

Viruses are a key regulator of the microbial carbon cycle in the deep-sea biosphere [PDF]
The marine biosphere profoundly influences atmospheric chemistry and climate through its carbon cycle. Viruses, the most abundant and diverse entities in marine ecosystems, significantly shape global carbon dynamics by infecting microbes and altering ...

Advances in Defining Ecosystem Functions of the Terrestrial Subsurface Biosphere
The subsurface is one of the last remaining ‘uncharted territories’ of Earth and is now accepted as a biosphere in its own right, at least as critical to Earth systems as the surface biosphere.
