In-situ detection of microbial life in the deep biosphere in igneous ocean crust [PDF]

Frontiers in Microbiology, 2015
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

The smallest in the deepest: the enigmatic role of viruses in the deep biosphere. [PDF]

Natl Sci Rev, 2023
It is commonly recognized that viruses control the composition, metabolism, and evolutionary trajectories of prokaryotic communities, with resulting vital feedback on ecosystem functioning and nutrient cycling in a wide range of ecosystems.

Shaping of the Present-Day Deep Biosphere at Chicxulub by the Impact Catastrophe That Ended the Cretaceous [PDF]

Frontiers in Microbiology, 2021
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 ...

Accessing the energy-limited and sparsely populated deep biosphere: achievements and ongoing challenges of available technologies [PDF]

Progress in Earth and Planetary Science, 2023
Microbes in marine sediments detected and counted by direct observation of membrane-filtered sediment samples stained with acridine orange. This technique can still be applied to high-biomass (> 105 cells/cm3) sedimentary habitats, such as organic-rich ...

Marine Deep Biosphere Microbial Communities Assemble in Near-Surface Sediments in Aarhus Bay. [PDF]

Front Microbiol, 2019
Analyses of microbial diversity in marine sediments have identified a core set of taxa unique to the marine deep biosphere. Previous studies have suggested that these specialized communities are shaped by processes in the surface seabed, in particular ...

Metatranscriptomes Reveal That All Three Domains of Life Are Active but Are Dominated by Bacteria in the Fennoscandian Crystalline Granitic Continental Deep Biosphere [PDF]

mBio, 2018
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

Deep-biosphere methane production stimulated by geofluids in the Nankai accretionary complex. [PDF]

Sci Adv, 2018
Scientific drilling at a submarine mud volcano shows that geofluid migration stimulates methanogenesis in the deep biosphere. Microbial life inhabiting subseafloor sediments plays an important role in Earth’s carbon cycle.

Exploring the Deep Marine Biosphere: Challenges, Innovations, and Opportunities

Frontiers in Earth Science, 2019
The deep marine biosphere is one of the largest, and yet least explored, microbial habitats on the planet. Quantifying the extent, diversity, and activity of subsurface microbial communities is a crucial part of understanding their role in global ...

Carbon in the Deep Biosphere [PDF]

Deep Carbon, 2019
Building on the synthesis of carbon reservoirs in Earth's subsurface, this chapter focuses on the forms, cycling, and fate of the carbon supporting microbial life in the terrestrial and marine subsurface. As the subsurface is estimated to host a vast reservoir of life on Earth, identifying the carbon compounds that life uses for energy and growth is ...
