Controls on faunal microdistribution and reproductive development in deep-sea chemosynthetic environments in the Antarctic

, 2014
There is no longer any part of the ocean that is inaccessible, however, spanning 361 million km2 across the earth's surface and, with approximately 50% of its volume at a depth greater than 2000 m, it is the very sheer size and complex nature of the deep

The geochemistry and geomicrobiology of relict hydrothermal sulphide deposits

, 2000
The diagenetic re-mineralisation of seafloor-sulphide deposits and the role of microbes in the metal-exchange processes were investigated in metalliferous sediments from the Alvin relict hydrothermal zone in the TAG area at 26º8'N (Mid-Atlantic Ridge ...

Hydrothermal sediments record changes in deep water oxygen content in the SE Pacific

, 2010
The distribution of redox?sensitive metals in sediments is potentially a proxy for past ocean ventilation and productivity, but deconvolving these two major controls has proved difficult to date.

Photosynthetic primary production in the Mesoproterozoic

New Phytologist, Volume 251, Issue 1, Page 64-80, July 2026.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Larval Dispersal and Connectivity of Bathymodiolus azoricus (Cosel & Comtet, 1999) at the Mid-Atlantic Ridge: Implications for Spatial Management of Hydrothermal Vent Communities

Journal of Marine Science and Engineering
Hydrothermal vents are “oases” of biological productivity and endemicity on the seafloor. Chemosynthetic communities at deep-sea hydrothermal vents are characterized by high abundance and endemism.

Hydrogen consumption by gills of Bathymodiolus spp. collected at the Comfortless cove and Lilliput hydrothermal vent fields in May 2006

, 2013
The discovery of deep-sea hydrothermal vents in 1977 revolutionized our understanding of the energy sources that fuel primary productivity on Earth. Hydrothermal vent ecosystems are dominated by animals that live in symbiosis with chemosynthetic bacteria.

Bridging Liquid and Gas Phase Catalysis for Abiotic CO2 Conversion to Prebiotic Organics Over Mesoporous Silica‐Supported Ni–Co Catalysts

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Under simulated hydrothermal vent conditions, Ni⋅Co bimetallic catalysts supported on silica convert CO2 and H2O into key metabolites such as formate, methanol, and ethanol. Water plays a critical role in CO2 adsorption and product selectivity, shaping catalytic performance across both liquid and gas phases.

Hydrothermal activity fuels microbial sulfate reduction in deep and distal marine settings along the Arctic Mid Ocean Ridges

Frontiers in Marine Science
Microbial sulfate reduction is generally limited in the deep sea compared to shallower marine environments, but cold seeps and hydrothermal systems are considered an exception.
