Disturbance Related Patterns in Fish Community Structure and Function in River Systems of the Lower Athabasca Oil Sands Region, Alberta
… impacts associated with land use disturbance and Oil Sands (OS) mining operations on fish community composition patterns in three rivers located in the Athabasca Oil Sands Region (AOSR). Using historical data sets, this thesis attempted to evaluate disturbance-related patterns in fish community …

Characterizing Hydrological Balance and Hydrochemistry of a Chronosequence of Newly Formed Wetlands within the Athabasca Oil Sands Region using Isotopic and Geochemical Tracers
… for approximately 65% of the land area of the oil sands surface mining region, many of which have been lost due to resource extraction. Mined areas are reclaimed using saline-sodic materials present in both surficial geology and residual tailings, affecting wetlands constructed or naturally …

Effects of Landscape Age and Salinity on Plant Community Composition and Productivity in Opportunistic and Constructed Wetlands in the Athabasca Oil Sands Region, Alberta
Wetlands comprise 65% of the Athabasca Oil Sands Region (AOSR) surface mineable area and thus support diverse flora (approximately 400 species in Alberta). Due to increased anthropogenic land disturbance activities such as bitumen extraction, reclamation of surface mineable areas will also …

Mapping Groundwater Discharges to Rivers near Oil Sands Projects
Groundwater discharges in the western Canadian oil sands region impact river water quality. Mapping groundwater discharges into rivers in the oil sands region is important to ensure wastewater and steam injections remain sequestered, rather than eventually resurfacing. Saline springs comprised of …

Evaluation and Application of Max-DOAS Methods for Monitoring Aerosols, NO2, and SO2 in Urban and Industrial Environments
… the comprehensive air quality campaign in the Athabasca Oil Sands Region in 2013 provided a rare opportunity to evaluate the performance of multiple aspects of the MAX-DOAS retrievals. Retrievals of aerosol extinction, NO2, and SO2 were compared to data from lidar, sun photometer, Active-DOAS, …

Oligotrophication of downwind boreal lakes caused by oil sands-derived enhanced nutrient deposition
Development of the Athabasca Oil Sands Region (AOSR) in northern Alberta, Canada has resulted in the substantial release of emissions, such as reactive nitrogen (Nr) species and base cations, which can fertilize downwind lakes in the boreal forest of Saskatchewan. However, to address the potential …
