Microbial Reefs in the Black Sea Fueled by Anaerobic Oxidation of Methane
Massive microbial mats covering up to 4-meter-high carbonate buildups prosper at methane seeps in anoxic waters of the northwestern Black Sea shelf. Strong 13C depletions indicate an incorporation ofExpand

Anaerobic oxidation of methane above gas hydrates at Hydrate Ridge, NE Pacific Ocean
At Hydrate Ridge (HR), Cascadia convergent margin, surface sediments contain massive gas hydrates formed from methane that ascends together with fluids along faults from deeper reservoirs. AnaerobicExpand

Environmental control on anaerobic oxidation of methane in the gassy sediments of Eckernförde Bay (German Baltic)
We investigated the effect of seasonal environmental changes on the rate and distribution of anaerobic oxidation of methane (AOM) in Eckernforde Bay sediments (German Baltic Sea) and identifiedExpand

Environmental regulation of the anaerobic oxidation of methane: a comparison of ANME-I and ANME-II communities.
The anaerobic oxidation of methane (AOM) is one of the major sinks for methane on earth and is known to be mediated by at least two phylogenetically different groups of anaerobic methanotrophicExpand

Consumption of Methane and CO2 by Methanotrophic Microbial Mats from Gas Seeps of the Anoxic Black Sea
ABSTRACT The deep anoxic shelf of the northwestern Black Sea has numerous gas seeps, which are populated by methanotrophic microbial mats in and above the seafloor. Above the seafloor, the mats canExpand

Anaerobic oxidation of methane and sulfate reduction along the Chilean continental margin
Anaerobic oxidation of methane (AOM) and sulfate reduction (SR) were investigated in sediments of the Chilean upwelling region at three stations between 800 and 3000 m water depth. Major goals ofExpand

Rising Arctic Ocean temperatures cause gas hydrate destabilization and ocean acidification
Vast amounts of methane hydrates are potentially stored in sediments along the continental margins, owing their stability to low temperature – high pressure conditions. Global warming couldExpand

Burrowing deeper into benthic nitrogen cycling: the impact of bioturbation on nitrogen fixation coupled to sulfate reduction
Biological dinitrogen (N2) fixation is the primary input of fixed nitrogen (N) into the marine biosphere, making it an essential process contributing to the biological functions of all organisms.Expand

Subsurface Microbial Methanotrophic Mats in the Black Sea
ABSTRACT A nodule-shaped microbial mat was found subsurface in sediments of a gas seep in the anoxic Black Sea. This mat was dominated by ANME-1 archaea and consumed methane and sulfateExpand
