Small scale, community based economic development in the Canadian Arctic
The term "northern development" in the Canadian Arctic is often associated only with large, non-renewable resource extraction projects. Other alternative development projects such as the co-operatives provide development on a scale that a community itself can manage and control. The "boom and bust" …

Hydrological and Hydrochemical Responses From Thawing Permafrost in the Canadian Arctic
… this research are to better understand: (1) how Arctic watersheds respond in terms of hydrological processes to deepening active layers, (2) what the short and long-term changes are to surface water chemistry in watersheds impacted by thermal and physical permafrost disturbances, (3) which key …

Polar Bear (Ursus Maritimus) Foraging Ecology in the Western Canadian Arctic
… prey. Due to their position at the top of the Arctic marine food web, polar bear foraging patterns can provide insights on ecosystem structure and function both spatially and temporally. This thesis used quantitative fatty acid signature analysis (QFASA) to estimate the diets, and adipose …

Calcite cements in carbonates of the Sverdrup Basin, Canadian Arctic Archipelago.
… sequences 2, 3 and 4 of the Sverdrup Basin (Canadian Arctic Archipelago) are the subject of this study. On a micro-scale, petrography with light microscopy, cathodoluminescence (CL), scanning electron microscopy (SEM) and staining helped to identify two main textural groups of cements, …

Ice Island Deterioration in the Canadian Arctic: Rates, Patterns and Model Evaluation
… known as ice islands, is limited within the Canadian Arctic. This study analyzed ice island deterioration through two aspects: 1) horizontal (areal) and 2) vertical (surface melt or ‘ablation’). Satellite images were digitized to monitor areal dimensions, classify deterioration modes and …

Inuit Harvesting Strategies in the Canadian Arctic and Implications for Wildlife Management
The thesis analyses two topics: native harvesting strategies and selected cases of over-exploitation. Its purpose is to assess the credibility of the assumption that hunter-gatherer societies do not have a system of self-regulation. Theoretical explanations and models are described to elicit …

Building skills : a construction trades training facility for the eastern Canadian Arctic
On April 1, 1999, the Inuit of the Eastern Canadian Arctic achieved sovereignty over a new territory, Nunavut, envisioning economic self-reliance, political self-determination, and renewal of confidence in Inuit community. Life in Nunavut, however, remains circumscribed by adversities: poverty, …

Remote Sensing of Vegetation Change Across a Latitudinal Gradient in the Canadian Arctic
… in a trend of greening across the Circumpolar Arctic. The spatial variability of warming and the inherent effects on plant communities has not proven to be uniform or homogeneous on global or local scales. We can apply remote sensing vegetation indices such as the Normalized Difference …

Oil from ice : examining the impact of energy development on Canadian Arctic sovereignty
The Canadian Arctic is facing new international challenges as global warming melts Arctic ice, opening up new shipping routes and access to untapped, potentially rich resources. As it has in the past, Canada is turning to defense spending to help strengthen its sovereignty in the region. …

Land Ice Monitoring via GRACE and Satellite Altimetry in the Canadian Arctic Archipelago
The Canadian Arctic Archipelago (CAA) was remarked as the third most significant contributor to the global sea level rise between 2003 and 2009, containing one third of the world’s freshwater as land ice (Gardner et al., 2011). Continuous monitoring of the long-term mass variability of the CAA is …

A Transfer Learning Approach for Automatic Mapping of Retrogressive Thaw Slumps (RTSs) in the Western Canadian Arctic
… Banks Island and Victoria Island in the western Canadian Arctic, where there is extensive RTS activity. We tested the model with different settings, including image band combinations, backbones, and backbone trainable layers, and performed hyper-parameter tuning and determined the optimal …

Methane-cycling microbial communities in permafrost affected soils on Herschel Island and the Yukon Coast, Western Canadian Arctic
… the Yukon Coast. Despite the relevance of the Canadian Western Arctic in the global methane budget, the permafrost microbial communities there have thus far remained insufficiently characterized. Through the study of methanogenic and methanotrophic microbial communities involved in the …

Marine microbial communities capable of hydrocarbon biodegradation along shipping routes in the Kivalliq region of the Canadian Arctic
… extreme cold and icy marine environment in the Canadian Arctic is not well understood regarding its potential for biodegradation of oil spills. Reduced ice cover due to climate change has led to increased human activities, with attendant risks of oil and fuel spills associated with shipping …
