The discovery of chemosynthetic ecosystems at deep-sea hydrothermal vents in 1977
changed our view of biology. Chemosynthetic bacteria and archaea form the foundation of …

The majority of life on Earth—notably, microbial life—occurs in places that do not receive
sunlight, with the habitats of the oceans being the largest of these reservoirs. Sunlight …

The aqueous alteration of ultramafic rocks through serpentinization liberates mantle carbon
and reducing power. Serpentinization occurs in numerous settings on present day Earth …

Arguments for an abiotic origin of low-molecular weight organic compounds in deep-sea hot
springs are compelling owing to implications for the sustenance of deep biosphere microbial …

Hydrothermal circulation and alteration at mid-ocean ridges and ridge flanks have a key role
in regulating seawater chemistry and global chemical fluxes, and support diverse …

Abstract The ultraslow-spreading Southwest Indian Ridge is a major tectonic province,
representing one of the important end-member mid-ocean-ridge types for its very slow and …

The InterRidge Vents Database is available online as the authoritative reference for
locations of active submarine hydrothermal vent fields. Here we describe the revision of the …

In nearly four decades since the discovery of deep-sea vents, one-third of the length of
global oceanic spreading ridges has been surveyed for hydrothermal activity. Active …

Members of the bacterial genus Sulfurimonas (phylum Campylobacterota) dominate
microbial communities in marine redoxclines and are important for sulfur and nitrogen …

Chemolithotrophy is a pervasive metabolic lifestyle for microorganisms in the dark ocean.
The SAR 324 group of D eltaproteobacteria is ubiquitous in the ocean and has been …
