Tracing methane sources in shallow waters of the North Sea: Biogenic signatures and hydrocarbon transport near abandoned wells

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Numerous abandoned wells in the North Sea may provide gas, particularly methane (CH4), migration pathways by penetrating shallow, biogenic gas accumulations. However, related sampling campaigns have been largely contradictory and lack a substantial database. Research cruise MSM98 targeted the abandoned wells B18‐1, DOK 1‐X, B11‐2, THOR and D‐1

Methanotrophic activity and diversity of methanotrophs in volcanic geothermal soils at Pantelleria (Italy) [PDF]

Biogeosciences, 2014
Abstract. Volcanic and geothermal systems emit endogenous gases by widespread degassing from soils, including CH4, a greenhouse gas twenty-five times as potent as CO2. Recently, it has been demonstrated that volcanic or geothermal soils are not only a source of methane, but are also sites of methanotrophic activity. Methanotrophs are able to consume 10–

Responses of methanogenic and methanotrophic communities to elevated atmospheric CO2 and temperature in a paddy field

Frontiers in Microbiology, 2016
Although climate change is predicted to affect methane (CH4) emissions in paddy soil, the dynamics of methanogens and methanotrophs in paddy fields under climate change have not yet been fully investigated.

Primary productivity coupled to oxic methane production in coastal waters of southern China

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Oxic methane (CH4) production (OMP) occurs in diverse oxygenated surface waters worldwide. However, phytoplankton‐driven OMP in natural marine environments remains poorly documented. During a research cruise in the highly productive southern East China Sea, we measured OMP by incubating phytoplankton‐rich surface waters and found that CH4 ...

Thermophilic methanotrophs: in hot pursuit

FEMS Microbiology Ecology, 2019
ABSTRACTMethane is a potent greenhouse gas responsible for 20–30% of global climate change effects. The global methane budget is ∼500–600 Tg y−1, with the majority of methane produced via microbial processes, including anthropogenic-mediated sources such as ruminant animals, rice fields, sewage treatment facilities and landfills.

Thermophilic methane oxidation is widespread in Aotearoa-New Zealand geothermal fields

Frontiers in Microbiology, 2023
Geothermal areas represent substantial point sources for greenhouse gas emissions such as methane. While it is known that methanotrophic microorganisms act as a biofilter, decreasing the efflux of methane in most soils to the atmosphere, the diversity ...

Methane emissions from canals draining tropical peatlands: Constraining temporal variability and emissions pathways

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Drainage canals are potential hotspots of methane (CH4) emissions from degraded peatlands in Southeast Asia. Estimates of CH4 emissions from these canals remain scarce, and both the temporal variability and pathways of CH4 emissions are uncertain.

Biotic interactions in microbial communities as modulators of biogeochemical processes: Methanotrophy as a model system.

Frontiers in Microbiology, 2016
Microbial interaction is an integral component of microbial ecology studies, yet the role, extent, and relevance of microbial interaction in community functioning remains unclear, particularly in the context of global biogeochemical cycles.

Organic Waste Diversion in the United States Can Substantially Reduce Landfill Methane Emissions But Plays a Minor Role in Nutrient Recycling

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract The decomposition of organic waste in landfills accounts for 17% of US anthropogenic methane (CH4) emissions. Despite ongoing efforts to reduce organic waste disposal in landfills, it is unclear what the emissions mitigation and nutrient recovery potential of landfill diversion is, across facility, state, and national scales.

Revising the Magnitude and Trends of the Global Methane Soil Sink With Process‐Based, Machine‐Learning, and Atmospheric Inversion Modeling Approaches

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Methane (CH4) oxidation by microbes is the largest biological sink of global methane, yet its magnitude and long‐term variability remain uncertain. Here, we combined process‐based (PB), machine‐learning (ML), and atmospheric inversion approaches to evaluate the global methane soil sinks and its implication for the atmospheric CH4 budget in ...
