A 15,800-year record of atmospheric lead deposition on the Devon Island Ice Cap, Nunavut, Canada: Natural and anthropogenic enrichments, isotopic composition, and predominant sources
Download2007
Zheng, J., Fisher, D., Krachler, M., Shotyk, W.
Abstract: Using appropriate clean methods for handling and preparation, 57 ice samples from the Devon Island Ice Cap, representing the period 134 to 15,800 years before present (BP), were analyzed for Pb, Sc, and Pb isotopes (Pb-206, Pb-207, Pb-208) using ICP-SMS. The greatest Pb concentrations...

Achieving Conservation when Opportunity Costs Are High: Optimizing Reserve Design in Alberta’s Oil Sands Region
Download2011-08-17
Using Alberta, Canada, as a case study we use a trade-off analysis to systematically explore the relationship between conservation targets and economic opportunity costs in the context of coarse-filter reserve design. We use the Marxan conservation planning software to generate reserve designs at...

Perkins, S., Zuidhof, Martin J., Feddes, John J. R., Robinson, Frank E.
Four environmental chambers housing either 75 (5.5 birds/m\") or 37 turkeys (2.8 birds/m ) were used to study the impact of stocking density on air quality, bird health, and performance under similar per bird ventilation rates (3 L/s per bird). Stocking density had little effect on air quality or...

Boreal wetlands play an important role in global carbon balance. However, their ecosystem function is threatened by direct anthropogenic disturbance and climate change. Oil sands surface mining in the boreal regions of Western Canada denudes tracts of land of organic materials, leaves large areas...

For much of the history of Alberta’s tar sands, a series of visual conventions have shaped Canadian imaginaries of the resource, the emergence of the non-conventional oil industry, and the mining of oil. We introduce a series of archival images dating from 1880 until the opening of Great Canadian...

Reclamation of slurry materials such as mine tailings requires effective management of consolidation-induced water release in the long-term. This is particularly challenging for flocculated or thickened tailings which require excessive time to fully consolidate to the final landform due to their...

Abstract: Fine tails, the resulting fine waste from oil sand processing, undergoes large-strain consolidation in tailings ponds. Its consolidation behavior must be analyzed using a large-strain consolidation theory, which requires the determination of the relationship between the void ratio and...

Progressive failure analysis of windrow induced slope movements at the Syncrude Limited mine site
Download1997
Chan, D. H., Mathioudakis, M., Morgenstern, N. R.
The presence of Marine Sediments below the operating bench in the Syncrude Canada Limited oil sand mine (NE Alberta, Canada) has negatively affected dragline mining operation. Any material that exhibits strain softening behaviour is prone to progressive failure. The Marine Clays at the Syncrude...

Chanasyk, D. S., Leatherdale, J., Quideau, S. A.
Large oil sands deposits in the Athabasca oil sands region of Alberta, Canada, are recovered through surface mining, creating a large-scale disturbance. Reclamation requires reconstruction of soil profiles to return the land to equivalent land capability and support the required end land use....
