Arctic greenhouse gas sinks: exploring coldspots of methane and nitrous oxide in the permafrost domain

CORDIS · observation · Publication date unknown

y novel mechanisms underlying Arctic greenhouse gas uptake. High-resolution, laser-based measurements of soil CH4 and N2O uptake at field sites in Canada, Greenland, and Finland will be combined with machine learning tools and in-depth studies of environmental drivers in sophisticated experimental manipulations. COLDSPOT applies a multi-scale approach combining field-based measurements of multiple gas species with climate simulation experiments in state-of-the-art climate chambers in the laboratory, and investigations ranging from the microbial scale, via soil and plant processes to ecosystem-scale models. COLDSPOT will generate new process-understanding, fundamentally transform our perception of the magnitude and functioning of greenhouse gas sinks in the Arctic, and provide breakthrough insights for Arctic and global greenhouse gas research.
