Summary
This project will use a combination of microbial analysis by the PhD student studying methanogenic and methanotrophic activity and community composition in selected pan-Arctic samples under in situ temperature conditions (4°C) and the IPCC 2013 Arctic climate change scenario (10°C).

Project description: Arctic permafrost soils store large amounts of organic matter that is sensitive to temperature increases and subsequent microbial degradation to methane (CH4) and carbon dioxide (CO2). In Arctic ecosystems CH4 contributes to up to half of the expected climate forcing when taking the global warming potential into account. The goal of this project is to study the dynamic landscape scale fluxes and the microbial mechanisms that underlie the contributions of the Arctic to the global greenhouse gas budget. The linkage between the actual microbes and landscape scale fluxes, however, is elusive. This project will use a combination of microbial analysis by the PhD student studying methanogenic and methanotrophic activity and community composition in selected pan-Arctic samples under in situ temperature conditions (4°C) and the IPCC 2013 Arctic climate change scenario (10°C). Activity studies will be carried out with and without addition of methanogenic and methanotrophic substrates to stimulate methane cycling activity, and sample and data collection and interpretive modelling will be carried out at the VU.
