Tracing microbial mediation processes on permafrost-carbon feedback to global warming
Arctic permafrost (PF) constitutes an immense carbon stock held in surface soils on land, coastal Pleistocene Ice Complex deposits and shallow subsea sediment in the Arctic area. During thawing, the emission of greenhouse gases CO2 and CH4 could further intensify global warming. The microbial degradation of organic matter that occurs within the process is crucial to understanding the biogeochemical carbon cycle and the prediction of future greenhouse gas emission in the Arctic. The EU-funded TCFLAND2SEA project aims to shed light on microbial mediation processes on PF-carbon feedback to global warming through the multidisciplinary quantitative estimation of microbial activity and metabolism in different PF types.
