Spring 2010
Carbon isotope analyses of gases extracted from drilling muds while drilling in the Western Canada Sedimentary Basin (WCSB) can be used to create carbon isotopic depth profiles. These profiles provide essentially continuous data through the stratigraphic section, offering a unique opportunity to...

Nutrient Loading of Aspen, Jack Pine and White Spruce Seedlings for Potential Out-planting in Oil Sands Reclamation
DownloadFall 2012
Low nutrient availability and competing vegetation are some of the issues facing tree crop establishment for land reclamation in the oil sands region. A possible solution to both problems is to load seedlings with nutrients while they are in the nursery. Here, I report on results from a research...

Patterns of stream temperature and the influence of groundwater in northern Rocky Mountain watersheds
DownloadFall 2023
Stream temperature is an important water quality parameter linked to biotic and abiotic processes that influence the abundance and distribution of aquatic organisms. Stream temperatures can be highly variable through space and time and are determined by energy flux processes. Key energy flux...

Physics of wastewater flow and pathogen transport processes from a soil-based at-grade effluent treatment system and associated groundwater contamination risks in Alberta, Canada
DownloadSpring 2015
Understanding of wastewater flow and transport processes and treatment effectiveness through the soil-absorption field of soil-based wastewater treatment systems remains a challenge. In addition, Alberta regulators and the on-site wastewater industry wanted to quantify the effectiveness of the...

Regional Groundwater Modelling for Flow Analysis and Investigation of Alternative Water Resources in the Edmonton Region, Alberta, Canada
DownloadFall 2022
Water resources in the Edmonton region are expected to be increasingly threatened by climate change and/or contamination in the coming decades. Currently, the sole source of water for the city of Edmonton is the North Saskatchewan River (NSR). This makes Edmonton vulnerable to changes in water...

Spring 2012
Twelve deep aquifers and 12 aquitards were defined in southwestern Saskatchewan. Four major water types were identified: Type 1 (Ca-SO4) freshwaters, found in Paleozoic aquifers; Type 2 (Na-Cl) brines, found in all aquifers; Type 3 (Na-SO4) waters, mixture of Type 1 and Type 2 waters; and Type 4...

Saproxylic Beetles (Coleoptera) Associated With Aspen Deadwood in Broad-Leaved Boreal Mixedwood Stands
DownloadFall 2012
I assessed deadwood-associated (i.e., ‘saproxylic’) beetles (Coleoptera) along a decay gradient of trembling aspen in mature deciduous stands of the boreal mixedwood forest in NW Alberta. Various collection methods were employed to sample saproxylic beetle species. Assemblages differed between...

Fall 2015
The recent open pit mining for oil sands in the Athabasca Oil Sands Region (AOSR), northern Alberta has created an unprecedented industrial scale disturbance whose ecological consequences is not well understood, and requires intensive investigation. This study focused on the temporal dynamics of...

The effects of subsoil ripping on soil physical properties and soil water dynamics on reconstructed soils at Genesee Prairie Mine, Alberta
DownloadSpring 2014
Surface mining activities have significantly depleted natural tree cover, especially trembling aspen (Populus tremuloides), in the Boreal Forest and Aspen Parkland Natural Regions of Alberta. The natural soil profile is usually destroyed during these mining activities and soil and landscape...
