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...

Fall 2023
Piles are commonly used in the Canadian Arctic as a foundation solution. Steel pipe shaft pile, which is a conventional pile type in the Arctic, is placed in an oversized pre-drilled hole and then the annulus is backfilled with gravel slurries or grout designed to cure (i.e., a process called...

Fall 2022
In order to understand permafrost and paleoenvironmental conditions in the Mackenzie Delta Region, permafrost cores were collected in the winter of 2017, near the newly developed Inuvik-Tuktoyaktuk Highway (ITH), NWT, by the NWT Geological Survey, NWT Department of Infrastructure, the University...

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...

Optimization of a Cover Design for Acid Rock Drainage Prevention in a Permafrost Environment
DownloadFall 2021
The extraction of sulfide-bearing waste rock can contribute to the generation of acid rock drainage (ARD). ARD is the effluent generated due to the oxidation of sulfide minerals which can be toxic to the receiving environment. Waste rock material which contains potentially acid-generating (PAG)...

Influence of permafrost characteristics on vegetation change in Yukon and Northwest Territories, Canada
DownloadFall 2021
Permafrost thaw is a significant contributor to landscape change and ecosystem disruption in northern systems. While previous studies have examined the impact of permafrost on vegetation change, few have investigated the connection of permafrost characteristics to the type and extent of...
