Greenhouse gas flux data for peatlands in Northwest Territories and Northern Alberta, 2021
2025-04-14
Lorna I Harris, Christopher Schulze, Kate Marouelli, Lauren Thompson, Renae Shewan, David Olefeldt
Closed-chamber greenhouse gas fluxes (methane, CH4; carbon dioxide, CO2) were measured in July and August of 2021 from peatland subsites (peat plateaus, bogs, and fens) at the research sites Lutose (AB), Scotty Creek (NWT), and Smith Creek (NWT). All CO2 fluxes are calculated as the change in...

Impacts on Water Quality at a Newly Opened and Extracted Peatland: Influence of Internal Processes and Hydrological Connectivity in Horticultural Peat Harvesting
DownloadSpring 2024
Horticultural peat harvesting continues to expand in Canada, yet the impact to downstream water quality during the initial stages of peatland opening and peat extraction are poorly understood. Major changes can occur to the hydrology and internal processes within a peatland during the transition...

Methylmercury production and export across the terrestrial-aquatic continuum in permafrost peatland catchments
DownloadFall 2023
Ongoing permafrost thaw in northern peatland catchments may increase the production and downstream delivery of neurotoxic methylmercury (MeHg) across the terrestrial-aquatic continuum. Peatlands in boreal-Arctic regions have large stocks of mercury (Hg) in frozen soils, accumulated through...

Soil and porewater chemistry from peatlands of the Interior Plains, northwestern Canada
2022-11-09
Thompson, L. M., Olefeldt, D., Mangal, V., Knorr, K.H.
The xlsx files contain one "ReadMe" tab and one "Data" tab regarding the chemistry of peatland soils or porewater. The "ReadMe" tab details the variable name, units, description, citation (optional), laboratory, and vocabulary terms. The "Data" tab contains data collected from twelve wetlands...

Spring 2020
Permafrost peatlands in northern regions store a significant proportion of global soil carbon and have historically played an important role in global carbon cycling. Recent warming is accelerating permafrost thaw and causing thermokarst formation. Thermokarst formation in peatlands leads to a...

The use of peat applications and Carex aquatilis for peatland reclamation on post mined landscapes in northern Alberta, Canada
DownloadFall 2018
I investigated peatland reclamation factors in a wetland built on a former open-pit oil sands mine in northern Alberta, Canada. The primary research objectives were to investigate the persistence of peat placed in a newly constructed wetland, the survival and establishment of Carex aquatilis...
