Viruses are a key regulator of the microbial carbon cycle in the deep-sea biosphere [PDF]

open access: yesEnvironmental Science and Ecotechnology
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 ...

Many Methods, Many Microbes: Methodological Diversity and Standardization in the Deep Subseafloor Biosphere [PDF]

open access: bronze, 2016
Standardization is widely assumed to be important to advance science. This assumption is typically embedded in initiatives to devise infrastructure and policies to support scientific work.

Advances in Defining Ecosystem Functions of the Terrestrial Subsurface Biosphere

open access: yesFrontiers in Microbiology, 2022
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.

ICDP drilling of the Eger Rift observatory: magmatic fluids driving the earthquake swarms and deep biosphere

open access: yesScientific Drilling, 2022
. The new in situ geodynamic laboratory established in the framework of the ICDP Eger project aims to develop the most modern, comprehensive, multiparameter laboratory at depth for studying earthquake swarms, crustal fluid flow, mantle-derived CO2 and ...

Dissolved Microbial Methane in the Deep Crystalline Crust Fluids–Current Knowledge and Future Prospects

open access: yesGeofluids, 2022
Methane is a powerful greenhouse gas, of which most is produced by microorganisms in a process called methanogenesis. One environment where methanogenic microorganisms occur is the deep biosphere.

Microbial Life of the Deep Biosphere

open access: yes, 2014
This book brings together a variety of topics, covering the broad range of issues that are associated with deep biosphere exploration. In order to explain our observations from deep subsurface ecosystems it is necessary to develop interdisciplinary approaches, ranging from microbiology and geochemistry to physics and modeling.

Weighing the deep continental biosphere [PDF]

open access: yesFEMS Microbiology Ecology, 2013
There is abundant evidence for widespread microbial activity in deep continental fractures and aquifers, with important implications for biogeochemical cycling on Earth and the habitability of other planetary bodies. Whitman et al. (P Natl Acad Sci USA, 95, 1998, 6578) estimated a continental subsurface biomass on the order of 10(16) -10(17) g C.

The hadal zone is an important and heterogeneous sink of black carbon in the ocean

open access: yesCommunications Earth & Environment, 2022
Black carbon accumulation rates in hadal trenches in the deepest regions of the oceans could be seven-fold higher than the global ocean average, according to geochemical and isotopic analyses of sediments from six trenches in the Pacific Ocean.
