CAPTURE addresses one of the grand research challenges of the 21st century: the role of the carbon cycle in regulating Earth’s climate. In particular, C dynamics of Arctic regions are a highly uncertain component of global C budgets. The overriding objective of CAPTURE is to enhance our understanding of the fate and transfer of C across the Arctic landscape gradients and the consequences for atmospheric GHG (CO2, CH4) concentrations and climate. One of the main originalities of the research is assessing the C cycling processes across spatial (from experimental plots to small catchments to regions and finally to a wider segment of the Euro-Asian Arctic) and temporal (the past two millennia, present, future) scales, in order to advance our understanding of C dynamics, climate variability and the risks of unwelcome C cycle feedbacks.
