A molecular phylogenetic approach was used to characterize the composition of microbial
communities from two gas hydrate sedimentary systems in the Gulf of Mexico. Nucleic acids …

Large amounts of methane, a potent greenhouse gas, are produced in anoxic sediments by
methanogenic archaea. Nonetheless, over 90% of the produced methane is oxidized via …

Archaea and bacteria are distributed throughout the sediment; however, our understanding
of their biodiversity patterns, community composition, and interactions is primarily limited to …

Marine sediments are a microbial biosphere with an unknown physiology, and the
sediments harbor numerous distinct phylogenetic lineages of Bacteria and Archaea that are …

Cold seeps are widespread chemosynthetic ecosystems in the deep-sea environment, and
cold seep microbial communities of the South China Sea are poorly constrained. Here we …

Methane hydrate in the South China Sea (SCS) has extensively been considered to be
biogenic on the basis of its δ 13 C and δD values. Although previous efforts have greatly …

Gas hydrates deposited in subseafloor sediments are considered to primarily consist of
biogenic methane. However, little evidence for the occurrence of living methanogens in …

Hadal sediments are hotspots of microbial activity in the deep sea and exhibit strong
biogeochemical gradients. But although these gradients are widely assumed to exert …

Abstract The Deepwater Horizon (DWH) oil spill in the spring of 2010 resulted in an input
of∼ 4.1 million barrels of oil to the Gulf of Mexico;> 22% of this oil is unaccounted for, with …

We investigated coupling between sulfate reduction (SR) and anaerobic oxidation of
methane (AOM) by quantifying pore water geochemical profiles, determining rates of …
