Microbial ecology of the dark ocean above, at, and below the seafloor
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 …

A critical look at iron paleoredox proxies: New insights from modern euxinic marine basins
TW Lyons, S Severmann - Geochimica et Cosmochimica Acta, 2006 - Elsevier
Enrichments in reactive iron occur under euxinic marine conditions, that is, where dissolved
sulfide is present in the water column. These enrichments result primarily from the export of …

How sulfate-driven anaerobic oxidation of methane affects the sulfur isotopic composition of pyrite: A SIMS study from the South China Sea
Sulfate-driven anaerobic oxidation of methane (SO 4-AOM) in marine sediments commonly
leads to the precipitation of pyrite. It is, however, frequently challenging to unequivocally …

Tracking euxinia in the ancient ocean: a multiproxy perspective and Proterozoic case study
The evolution and extinction of life are tied intimately to the oxygen state of the ocean, and
particularly to the presence of anoxic and H2S-containing (euxinic) water on a global scale …
