Study Site: Boreal Shield peatland in Ontario, Canada
Purpose: Peatlands are globally important long-term sinks of atmospheric carbon dioxide (CO2). However, there is concern that climate change-mediated drying will reduce gross primary productivity (GPP) and increase ecosystem respiration (ER) making peatlands vulnerable to a weaker carbon sink function and potential net carbon loss. While large and deep peatlands are usually resilient to moderate summer drying, CO2 exchange in shallow Boreal Shield peatlands is likely more sensitive to drying given the reduced groundwater connectivity and water storage potential. To better understand the carbon cycling responses of Boreal Shield peatlands to meteorological conditions, we examined ecohydrological controls on CO2 fluxes using the eddy covariance technique at a shallow peatland during the summer season for 5 years, from 2016–2020.
Abstract: This dataset contains daily growing season measurements of CO2 flux and ancillary measurements at a Boreal Shield peatland in Ontario, Canada.
