The changing influence of permafrost on peatlands hydrology
(University of Waterloo, 2021-01-20)Hydrology and hydrological modelling in the far north is understudied, and many gaps exist in the current understanding and representation of northern thermal and hydrological systems. A combination of fieldwork and modelling ... -
Characterizing Aspects of Groundwater Flow in Discontinuous Permafrost Terrain, Within the Central Mackenzie Valley, NWT
(University of Waterloo, 2021-05-26)With recent developments in oil and gas exploration technologies that have opened regions of Canada’s northern territories and the threat of climate change, uncertainties around how these factors may impact the environment ... -
Evaluating Thermal Regime of Cold Region Roads for Climate Change Adaptation
(University of Waterloo, 2020-04-07)Nearly a quarter of the Northern Hemisphere is underlain with permafrost, of which discontinuous permafrost is most sensitive to the temperature of its surrounding. Climate change and the implementation of infrastructure ... -
Evolution of Canadian Shield Groundwaters and Gases: Influence of Deep Permafrost
(University of Waterloo, 2008-09-24)Numerous glacial advances over the past 2 million years have covered the entire Canadian and Fennoscandian Shield outcrop. During glacial advance and retreat, permafrost is expected to form in front of the glacier. The ... -
Geophysical Methods for Detecting Permafrost Discontinuities
(University of Waterloo, 2021-03-04)Global climate change has sparked various concerns over the future of the Arctic. One of the major concerns around the environmental and ecological health of the Arctic is directly related to the deterioration of the ... -
The Impact of Glaciation and Permafrost on Groundwater Flow
(University of Waterloo, 2016-03-21)Current geologic and climatic conditions need to be considered when choosing an appropriate site for a Deep Geologic Repository (DGR). However, given the million-year timeframe for the radioactivity of the used fuel to ... -
An Index of Groundworks and Bearings: Architectural lessons on foundation building in Vuntut Gwitchin traditional territory
(University of Waterloo, 2018-04-30)The foundation mediates the relationship between a building and the land. It is a connection that is particularly challenging to ground in frozen soils. Bridging the Arctic Circle in the Northern Yukon, Vuntut Gwitchin ... -
An integrative study on the controls of mercury (Hg) in the sediments and food webs of thermokarst lakes on the Arctic Coastal Plain of Alaska
(University of Waterloo, 2019-07-26)Arctic freshwater ecosystems are subject to profound climate-driven changes. Air temperatures are rising, leading to changes that include increased primary production and enhanced permafrost degradation. These and other ... -
Modeling of Permafrost Distribution in the Semi-arid Chilean Andes
(University of Waterloo, 2014-01-02)The distribution of mountain permafrost is generally modeled using a combination of statistical techniques and empirical variables. Such models, based on topographic, climatic and geomorphological predictors of permafrost, ... -
Temporal Deep Learning Approach to Bedfast and Floating Thermokarst Lake Ice Mapping using SAR imagery: Old Crow Flats, Yukon, Canada
(University of Waterloo, 2021-09-17)Lake ice is a fundamental part of the freshwater processes in cold regions and a sensitive indicator of climate change. As such, in light of the recent climate warming, monitoring of lake ice in arctic and sub-arctic regions ... -
Thermal and Hydrological Response of Rock Glaciers to Climate Change: A Scenario Based Simulation Study
(University of Waterloo, 2014-01-17)Snow and glaciers are considered the most important sources of the estimated 32-60% of global water resources which are provided by mountains. Consequently, snow and glaciers have regularly been the focus of climate change ... -
Using Machine Learning to Understand the Hydrologic Impacts of Permafrost Thaw-Driven Land Cover Change
(University of Waterloo, 2023-04-25)Discontinuous permafrost regions are experiencing a change in land cover distribution as a result of permafrost thaw. In wetlands interspersed with discontinuous permafrost, climate change is particularly problematic because ...
