Journal ArticleDOI
Geochemical evidence for iron-mediated anaerobic oxidation of methane
TL;DR: Anaerobic oxidation of methane (AOM) by sulfate has been recognized as a critical process to maintain this greenhouse gas stability by limiting methane flux to the atmosphere.
Journal ArticleDOI
Coupled sulfur and oxygen isotope insight into bacterial sulfate reduction in the natural environment
TL;DR: In this article, a model of the biochemical steps involved in bacterial sulfate reduction (BSR) was used to explore how the slope on a δ18OSO4 vs. δ34SSO4 plot relates to the net sulfate Reduction Rate (nSRR) across a diverse range of natural environments.
Journal ArticleDOI
Rates of methanogenesis and methanotrophy in deep-sea sediments
TL;DR: In this article, the carbon isotopic composition of pore fluids from Leg 175 of the Ocean Drilling Program (ODP) along the West African Margin was used to quantify rates of methane production (methanogenesis) and destruction via oxidation (mETHanotrophy) in deep-sea sediments.
Journal ArticleDOI
Co-existence of Methanogenesis and Sulfate Reduction with Common Substrates in Sulfate-Rich Estuarine Sediments.

TL;DR: The results show that methanogenesis and sulfate reduction can co-exist while the microbes share substrates over the tested range of sulfate concentrations and at sulfate Reduction rates up to 680 μmol L-1 day-1.
Journal ArticleDOI
Geochemical evolution and timescale of seawater intrusion into the coastal aquifer of Israel
TL;DR: In this paper, the authors quantify the geochemical processes and the timescale of seawater intrusion into a coastal aquifer from changes in the major ionic composition of the water and the natural distribution of the cosmogenic isotopes 14C and 3H.
