Suppression of methane uptake by precipitation pulses and long-term nitrogen addition in a semi-arid meadow steppe in northeast China

Frontiers in Plant Science, 2023
In the context of global change, the frequency of precipitation pulses is expected to decrease while nitrogen (N) addition is expected to increase, which will have a crucial effect on soil C cycling processes as well as methane (CH4) fluxes.

Belowground changes to community structure alter methane-cycling dynamics in Amazonia

Environment International, 2020
Amazonian rainforest is undergoing increasing rates of deforestation, driven primarily by cattle pasture expansion. Forest-to-pasture conversion has been associated with increases in soil methane (CH4) emission.

Pathways of methane removal in the sediment and water column of a seasonally anoxic eutrophic marine basin

Frontiers in Marine Science, 2023
Methane (CH4) is a key greenhouse gas. Coastal areas account for a major proportion of marine CH4 emissions. Eutrophication and associated bottom water hypoxia enhance CH4 production in coastal sediments.

Evaluation of Data Processing Strategies for Methane Isotopic Signatures Determined During Near-Source Measurements

Tellus: Series B, Chemical and Physical Meteorology
Mobile, near-source measurements are broadly used for determining δ13CH4 of individual methane (CH4) emissions sources. To answer the need for robust and comparable measurement methods, we aim to define the best practices to determine isotopic signatures

Migration and Release Mechanism of Methane Microseepage Based on Dawanqi Field Work and Physical Simulations

Geofluids, 2023
Methane (CH4) microseepage from petroleum basins is a significant contributor to the atmospheric CH4 budget. However, research about CH4 migration and release mechanism is still very limited.
