This dataset contains methane fluxes from peatland plateaus and thawing peatland plateaus and from burnt and unburnt forests from permafrost in subarctic Canada. Methane fluxes were monitored during summer in 2013 and 2014 in Yukon and Northwest Territories. Monitored sites included peatland plateaus and thawing features of peatland plateaus.

Methane flux measurements were performed by placing on the ground PVC-made collars and chambers and monitoring headspace concentrations over time. A portable methane gas analyser Detecto Pak-Infrared (DP-IR, Heath Consultants) was used to monitor methane concentrations. A certified gas standard was used to check the performance of the analyser. The slopes of the linear regression of methane concentrations and time were used to calculate the flux rates.
