50,000 years of paleoenvironmental change recorded in meteoric waters and coeval paleoecological and cryostratigraphic indicators from the Klondike goldfields, Yukon, Canada
DownloadFall 2015
A 50,000 year record of meteoric water isotopes (δ2H/δ18O) and paleoenvironmental conditions is presented from syngenetic ice-rich permafrost and macrofossils from eight sites in the Klondike area of central Yukon. Four sedimentary units are recognized based on cryostratigraphy, paleoecological...

A range-wide common garden experiment of white spruce indicates population differentiation in drought tolerance traits
DownloadFall 2019
In western regions of the Canadian boreal forest, mean annual temperature has increased by 1.5 to 2.5 °C, significantly exceeding the mean global temperature increase. Climate conditions have also become drier and together these climate trends have induced widespread growth reductions, dieback...

Application of SWAT-MODFLOW Software to Evaluate Groundwater-Surface Water Interaction in West-Central Alberta
DownloadFall 2018
Responsible watershed management is emerging as a key issue as humanity continues to place increasing demands on water resources. To meet future demands, it has become imperative that water resources be managed as a holistic system rather than solely focusing on individual aspects....

Land use and land use change strongly influence the carbon (C) dynamics within ecosystems. This study quantified four aspects of land use and land use change effects: 1) ecosystem C stocks and distribution; 2) soil respiration; 3) soil C mineralization; and 4) net ecosystem productivity. Land use...

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...

Development and application of the Re-Os isotope system to sediment-hosted Zn-Pb ores and sedimentary pore waters
DownloadFall 2018
The rhenium-osmium (Re-Os) isotopic system is used to determine the age of, and trace the origins of, minerals and fluids found within the Earth's crust. This thesis focuses on application of Re-Os geochronology and isotope systematics to sulphide minerals from carbonate-hosted Zn-Pb ore...

Development of High Efficiency and New Selectivity Liquid Chromatographic Phases for the Separation of Ionic and Hydrophilic Analytes
DownloadFall 2013
Separation of low molecular weight ions and hydrophilic analytes is achieved by high performance ion chromatography (IC) and hydrophilic interaction liquid chromatography (HILIC). The goal of this thesis was three-fold: to increase the efficiency of IC separations by employing small particles; to...

Diagenetic Controls on Hydrothermal Fluid Flow in the Osiris, Isis, and Isis East Carlin-Type Gold Showings, Nadaleen Trend, Yukon
DownloadFall 2015
Following ATAC Resources Ltd.’s 2010 discovery of the gold prospects in the Nadaleen Trend (Central Yukon), company geologists and consultants determined that Precambrian carbonate rocks within the trend contain large endowments of gold located in the hinges of anticlines and fault zones. ...
