This thesis utilises geomorphic mapping, cosmogenic nuclide dating, and numerical modelling, to reconstruct the timing and deglacial dynamics of the southwestern Laurentide Ice Sheet (SWLIS). A paucity of geomorphic data within the interior portions of the SWLIS is addressed through the mapping...

This thesis aims to develop a grounded understanding of the everyday experiences of disabled people in Almaty, Kazakhstan. The voices and needs of disabled people have been a long-ignored by state authorities as well as academics. This thesis intends to address this gap. I ask -- what are...

The mining industry generates vast amounts of geological material and diamond drill core throughout the life-cycle of any exploration or mining project. This material needs to be examined, logged, and assayed where appropriate. Currently this is generally performed through visual observations by...

Sharp, Iain

The goal of this thesis is to address the need to improve forestry monitoring and satellite validation techniques to better contextualize the effects that human-induced climate change is having on tropical dry forests (TDFs). Climate change is expected to change regional and global precipitation...

Gahcho Kué is a diamond mine in the Northwest Territories of Canada that opened in 2016. This is the first study into the morphology, N systematics, and stable isotope (C and N) composition of the Gahcho Kué diamonds, and the mineral chemistry of the associated inclusions. The resulting data are...

The Lower Triassic Montney Formation is a world class hydrocarbons reservoir in Alberta and British Columbia. Although commonly described as a shale, it is a siltstone over most of its subcrop, for which predictive models for reservoir quality properties such as porosity and permeability,...

Clay minerals are ubiquitous at the Earth’s surface and they impart a significant influence on numerous geochemical cycles due to their high surface reactivity. Aqueous pH and ionic strength (hereafter IS) are two major factors that affect clay surface reactivity and subsequently govern trace...

Banded iron formations (BIF) are iron-rich (~20-40% Fe), siliceous (~40-50% SiO2), and organic-lean (<0.5 wt.%) sedimentary deposits that precipitated widely during the late Archean (2.7-2.5 Ga) and Paleoproterozoic (2.5-1.8 Ga). As cyanobacteria evolved, the reaction between dissolved Fe(II) and...

Castro, Saulo M.

The main goal of this thesis is to contribute to the growing body of scientific work by exploring mechanisms of ecosystem productivity through the integration of remote sensing and micrometeorological data. This was done throughout by (i) identifying the environmental mechanisms affecting...

Interactions between predators and prey play an important role in structuring their communities and shaping evolution. However, human-induced climate change has the potential to influence both predators and prey and disrupt their interactions. The fossil record provides an enormous resource to...
