Ecological Response of Atmospheric Nitrogen Deposition on Reconstructed Soils in the Athabasca Oil Sands Region
DownloadSpring 2012
Oil and gas extraction in the Athabasca oil sands region has increased anthropogenic nitrogen (N) emissions over the past two decades. This study quantified atmospheric N deposition and assessed the potential implications of increased N deposition in aspen (Populus tremuloides Michx.) and jack...

Hydrogeological Considerations for Landscape Reconstruction and Wetland Reclamation in the Sub-humid Climate of Northeastern Alberta, Canada
DownloadFall 2019
Oil sands mining companies must reclaim tailings deposits to equivalent land capability in Alberta’s boreal forest. Post-mining landscapes should be reconstructed to promote the development of hydrologic systems that can sustain reclaimed ecosystems in a sub-humid climate, while limiting...

Nitrogen, plant and microbial community dynamics in sites recovering from wildfire and surface mining in the Athabasca Oil Sands Region
DownloadSpring 2016
For reclamation to be considered successful, an ecosystem must be self-sustaining and have a recovery trajectory that falls within the range of variability of ecosystem function in natural ecosystems. This study compared the soil nitrogen availability, soil microbial community, and understory...

The Geochemical Evolution of Oil Sands Tailings Pond Seepage, Resulting from Diffusive Ingress Through Underlying Glacial Till Sediments
DownloadFall 2012
Oil sands tailings are comprised of sands, silts, clays, and process-affected water (OSPW). The latter includes high concentrations of dissolved ions, as well as organic contaminants, making the water toxic to aquatic organisms. In Northern Alberta, tailings ponds are being constructed on...
