Methane is a potent greenhouse gas; methane production and consumption within seafloor
sediments has generated intense interest. Anaerobic oxidation of methane (AOM) and …

Deep‐sea environments are the largest ecosystem of the global biosphere and constitute a
crucial role in global biogeochemical cycles. We integrated biogeochemical and molecular …

Methylotrophic methanogenesis is often proposed to be responsible for methane production
in sulfate‐rich environments, yet the magnitude of this process remains elusive. In this study …

Marine surface sediments, which are replete with sulfate, are typically considered to be
devoid of endogenous methanogenesis. Yet, methanogenic archaea are present in those …

Although coastal sediments are major contributors to the production of atmospheric
methane, the effects of environmental conditions on methanogenesis and the community of …

Methane is the simplest hydrocarbon and a potent greenhouse gas that plays important
roles in atmospheric chemistry, the global carbon cycle, and the formation of gas hydrates in …

The anaerobic oxidation of methane (AOM) in the marine subsurface is a significant sink for
methane in the environment, yet our understanding of its regulation and dynamics is still …

Methanogenesis has recently been shown to fuel anaerobic oxidation of methane (AOM)
within the sulfate-reducing zone of marine sediments, coining the term “cryptic methane …

Methane seeps are widespread seafloor ecosystems shaped by complex physicochemical-
biological interactions over geological timescales, and seep microbiomes play a vital role in …

As marine sediments are buried, microbial communities transition from sulfate-reduction to
methane-production after sulfate is depleted. When this biogenic methane diffuses into the …
