Spring 2021
This thesis presents two studies employing computational approaches to tephra source attribution and tephra volume estimation. Glass major oxide data was used to train 11 classification algorithms. Each classifier probabilistically attributed tephra chemistries to one of ten volcanic sources from...

Biological Treatment of Naphthenic Acids and Other Organic Compounds in Oil Sands Process-Affected Waters
DownloadFall 2014
The Alberta oil sands contain one of the world’s largest reserves of oil - over 169 billion barrels of bitumen are economically recoverable with current extraction technologies. Surface mining, whereby the ore is extricated from the earth and bitumen is obtained via a hot water extraction...

Dissolved Organic Carbon Mobilization and Degradation Patterns in Retrogressive Thaw Slumps of the Peel Plateau, Northwest Territories, Canada
DownloadFall 2016
Anthropogenic climate change has affected the Canadian Arctic cryosphere, accelerating the development of retrogressive thaw slumps (RTS) across the Peel Plateau, NWT, Canada. RTS result from the thawing of ice-rich permafrost and develop due to ablation of ground ice exposed in the slump...

To ensure oil sands process water (OSPW) is suitable for discharge into the environment, advanced water treatment technologies are required. In this study, integrated ozonation-biodegradation was investigated as a potential treatment option for OSPW. The treatment efficiency was evaluated in...

Geology and geochemistry of late Devonian-Mississipian sediment-hosted barite sequences of the Selwyn Basin, NWT and Yukon, Canada
DownloadFall 2011
A sediment-hosted barite horizon occurs in the upper part of the lower Earn Group in the Selwyn Basin, NWT, Canada. This horizon consists of synsedimentary, laminated barite and diagenetic, nodular barite which are hosted in shale, siltstone and mudstone. The lithogeochemistry of the sediments...

Fall 2013
Boreal peatlands are widely considered as an important carbon sink. Peat moisture is important for controlling carbon sequestration and smouldering combustion. Retrieving surface moisture is of great interest for carbon budget modelling and fire management in peatlands. To monitor at a large...

Fall 2017
This thesis focuses on formulating and analyzing non linear models for microbial dynamics vis-a-vis human and environmental health. Firstly, we develop and investigate a stoichiometric organic matter decomposition model in a chemostat culture that incorporates the dynamics of grazers. This...

Conductive Atomic Force Microscopy Study of Electron Transport Through Diazonium Derived Films and Mixed – Mode Bonded Layers on Gold and Carbon Surfaces
DownloadSpring 2012
For Molecular Electronics to become a viable replacement or complitment to current elec- tronic devices a fundamental understanding of device operation and functionality is needed. This work explores electron transport through diazonium derived molecular junctions via conductive atomic force...

The genesis of the Gayna River carbonate-hosted Zn-Pb deposit
Fall 2009
Geochemical analyses on samples from the Mississippi Valley Type Gayna River deposit, Northwest Territories, Canada, have resulted in the definition of three ore stages and a deposit genesis model. Pb/Pb and Re/Os isotopic analyses indicate that the mineralization at Gayna River was emplaced...
