Phylogenetic diversity of microorganisms in subseafloor crustal fluids from boreholes 1025C and 1026B along the Juan de Fuca Ridge flank

Frontiers in Microbiology, 2014
To expand investigations into the phylogenetic diversity of microorganisms inhabiting the subseafloor biosphere, basalt-hosted crustal fluids were sampled from Circulation Obviation Retrofit Kits affixed to Holes 1025C and 1026B along the Juan de Fuca ...

Atribacteria Reproducing over Millions of Years in the Atlantic Abyssal Subseafloor

mBio, 2020
How microbial metabolism is translated into cellular reproduction under energy-limited settings below the seafloor over long timescales is poorly understood.

A Fungal-Prokaryotic Consortium at the Basalt-Zeolite Interface in Subseafloor Igneous Crust. [PDF]

PLoS ONE, 2015
We have after half a century of coordinated scientific drilling gained insight into Earth´s largest microbial habitat, the subseafloor igneous crust, but still lack substantial understanding regarding its abundance, diversity and ecology.

Geochemistry of Hydrothermal Fluids From the E2-Segment of the East Scotia Ridge: Magmatic Input, Reaction Zone Processes, Fluid Mixing Regimes and Bioenergetic Landscapes

Frontiers in Marine Science, 2022
The compositions of hydrothermal fluids in back-arc basins (BABs) can be affected by the influx of magmatic fluids into systems that are dominated by reactions between basement rocks and seawater-derived fluids.

Phylogenetic diversity and functional gene patterns of sulfur-oxidizing subseafloor Epsilonproteobacteria in diffuse hydrothermal vent fluids

Frontiers in Microbiology, 2013
Microorganisms throughout the dark ocean use reduced sulfur compounds for chemolithoautotrophy. In many deep-sea hydrothermal vents, sulfide oxidation is quantitatively the most important chemical energy source for microbial metabolism both at and ...

Microbial life in deep subseafloor coal beds [PDF]

Proceedings of the National Academy of Sciences, 2017
Deep beneath the seafloor, microbial communities thrive on the leftovers of organic material that in the past settled down from the surface layers of the ocean to the sediment. As the organic matter was buried deeper and deeper over geological time it became increasingly recalcitrant to microbial degradation. Microbial cells that still persist in these

The contribution of water radiolysis to marine sedimentary life

Nature Communications, 2021
The extent to which chemical products of water radiolysis could sustain subseafloor microbial life is unknown. Here the authors show that sediment catalyzes radiolytic production of H2 and oxidants, providing the primary energy source for life in ancient

The deep subsurface biosphere in igneous ocean crust: frontier habitats for microbiological exploration

Frontiers in Microbiology, 2012
We discuss ridge flank environments in the ocean crust as habitats for subseafloor microbial life. Oceanic ridge flanks, areas far from the magmatic and tectonic influence of seafloor spreading, comprise one of the largest and least explored microbial ...

Hybridisation capture allows DNA damage analysis of ancient marine eukaryotes

Scientific Reports, 2021
Marine sedimentary ancient DNA (sedaDNA) is increasingly used to study past ocean ecosystems, however, studies have been severely limited by the very low amounts of DNA preserved in the subseafloor, and the lack of bioinformatic tools to authenticate ...

Deep subseafloor microbial cells on physiological standby [PDF]

Proceedings of the National Academy of Sciences, 2011
Microscopic counts of microbial cells in deep sediment cores retrieved by scientific ocean drilling have revealed the largest living ecosystem on earth: the deep biosphere (1, 2). Hidden beneath the seafloor, a large part of all prokaryotic cells on earth persist under conditions so highly energy-limited that it seems to violate the constraints to life.
