Precambrian rocks host a deep hydrosphere, but where dissolved sulfate, crucial for microbial life, comes from is unclear. At 2.4 km depth in the Canadian shield, Li et al.

Deep-Sea Biodiversity in the Mediterranean Sea: The Known, the Unknown, and the Unknowable [PDF]
Deep-sea ecosystems represent the largest biome of the global biosphere, but knowledge of their biodiversity is still scant. The Mediterranean basin has been proposed as a hot spot of terrestrial and coastal marine biodiversity but has been supposed to ...

Integrative Genomics Sheds Light on Global Deep Terrestrial Biosphere Communities
Active microbial lineages inhabit the deep terrestrial subsurface (Fry et al. 1997, Lopez-Fernandez et al. 2018) with estimates suggesting deep subsurface ecosystems to host ca. 90% of the total bacterial and archaeal biomass on Earth and about 10-20% of

Fossilized Endolithic Microorganisms in Pillow Lavas from the Troodos Ophiolite, Cyprus
The last decade has revealed the igneous oceanic crust to host a more abundant and diverse biota than previously expected. These underexplored rock-hosted deep ecosystems dominated Earth’s biosphere prior to plants colonized land in the Ordovician,

Atribacteria Reproducing over Millions of Years in the Atlantic Abyssal Subseafloor
How microbial metabolism is translated into cellular reproduction under energy-limited settings below the seafloor over long timescales is poorly understood.

The deep, hot biosphere. [PDF]
There are strong indications that microbial life is widespread at depth in the crust of the Earth, just as such life has been identified in numerous ocean vents. This life is not dependent on solar energy and photosynthesis for its primary energy supply, and it is essentially independent of the surface circumstances.

Rare Biosphere Archaea Assimilate Acetate in Precambrian Terrestrial Subsurface at 2.2 km Depth
The deep biosphere contains a large portion of the total microbial communities on Earth, but little is known about the carbon sources that support deep life.

Towards understanding how surface life can affect interior geological processes: a non-equilibrium thermodynamics approach [PDF]
Life has significantly altered the Earth’s atmosphere, oceans and crust. To what extent has it also affected interior geological processes? To address this question, three models of geological processes are formulated: mantle convection, continental ...

Sulfate reduction in the deep biosphere.
Dissimilatory sulfate reduction is the quantitatively most important terminal electron acceptor process in marine sediments. Sulfate reducing microorganisms are known to be able to live under almost all pressure and temperature conditions that allow life.

Microbial communities in deep subsurface sediments are challenged by the decrease in amount and quality of organic substrates with depth. In sediments of the Baltic Sea, they might additionally have to cope with an increase in salinity from ions that ...
