Temperature sensitivity of anaerobic methane oxidation versus methanogenesis in paddy soil: Implications for the CH4 balance under global warming

The data corroborate a similar Q10 of AOM and methanogenesis and estimate the AOM in paddy soils to consume 2.2~5.5 Tg CH4 per year on a global scale, indicating that AOM is a highly temperature-dependent microbial process.

Biogeochemical reappraisal of the freshwater–seawater mixing‐zone diagenetic model

First proposed nearly half a century ago, the mixing‐zone model of dolomitization enjoyed a brief stay in the limelight before falling out of favour. Despite extended past criticism, arguments that

Lipid Biomarkers and Their Stable Carbon Isotopes in Oxic and Anoxic Sediments of Lake Bled (NW Slovenia)

ABSTRACT Sources of lipid biomarkers in two Lake Bled sediment cores deposited under oxic (Zaka Bay) and anoxic (WB) conditions were determined using stable carbon isotopes. Lipid biomarkers were of

Marine methane paradox explained by bacterial degradation of dissolved organic matter

A lot of methane is emitted from oxygenated seawater, where its production should be inhibited. Seawater incubations and organic matter characterizations reveal that bacteria aerobically produce

The Intergovernmental Panel on Climate Change (IPCC)

Recognizing the problem of a potential global climate change, the World Meteorological Organization ( WMO) and the United Nations Environment Programme ( UNEP) established the Intergovernmental Panel

Establishing criteria to distinguish oil-seep from methane-seep carbonates

Hydrocarbon seeps harbor copious chemosynthesis-dependent life, the traces of which are preserved in the fossil record within authigenic carbonates. These environments are mostly characterized by

Lipid biomarkers for anaerobic oxidation of methane and sulphate reduction in cold seep sediments of Nyegga pockmarks (Norwegian margin): discrepancies in contents and carbon isotope signatures

The present data reveal high discrepancies in the contents and δ13C values for both archaeal and bacterial lipid profiles, implying the possible involvement of at least two distinct AOM-related microbial consortia at the inferred AOM depth zonation of G11 and G12 pockmark sediments.

Aerobic production of methane in the sea

Methane is a potent greenhouse gas that has contributed approximately 20% to the Earth’s warming since pre-industrial times. The world’s oceans are an important source of methane, comprising 1–4% of
