SP2: Methane production & oxidation
Process studies on methane production and oxidation: from micro to pedon scale
The aim of this subproject (SP2) is to decipher the response of methane (CH4) cycle processes in permafrost-affected terrestrial ecosystems to climate change. The knowledge gained will be used to include into and improve model-based predictions of CH4 formation, oxidation, and release. To achieve this goal, TP2 investigates the effects of various biotic and abiotic environmental factors (soil water content, redox potential, temperature, organic matter quality, alternative electron acceptors, microbial food webs) on CH4 production, oxidation, and release of CH4 versus carbon dioxide (CO2), as well as their ages. To this end, TP2 combines (1) observations & measurements directly in the field in the tundra of Greenland at different seasons with (2) elaborate laboratory studies and experiments, including incubation of intact soil columns under different environmental conditions.
