Application of GNSS Interferometric Reflectometry for Lake Ice Studies
(University of Waterloo, 2020-10-20)This thesis examines the use of Global Navigation Satellite System Interferometric Reflectometry (GNSS-IR) for the study of lake ice with a particular focus on the estimation of ice thickness. Experiments were conducted ... -
Climatological trends and predictions in snowfall over the Canadian snowbelts of the Laurentian Great Lakes Basin
(University of Waterloo, 2018-06-11)The leeward shores of the Laurentian Great Lakes are highly susceptible to lake-induced snowfall that is either driven by extratropical cyclones or lake effect processes. During the late autumn and winter season, cold air ... -
Evaluation of Machine Learning Algorithms for Lake Ice Classification from Optical Remote Sensing Data
(University of Waterloo, 2020-06-02)The topic of lake ice cover mapping from satellite remote sensing data has gained interest in recent years since it allows the extent of lake ice and the dynamics of ice phenology over large areas to be monitored. Mapping ... -
Forward Modelling of Multifrequency SAR Backscatter of Snow-Covered Lake Ice: Investigating Varying Snow and Ice Properties Within a Radiative Transfer Framework
(University of Waterloo, 2023-01-19)Lakes are a key feature in the Northern Hemisphere landscape. The coverage of lakes by ice cover has important implications for local weather conditions and can influence energy balance. The presence of lake ice is also ... -
RADARSAT-2 Polarimetric Radar Imaging for Lake Ice Mapping
(University of Waterloo, 2017-11-21)Changes in lake ice dates and duration are useful indicators for assessing long-term climate trends and variability in northern countries. Lake ice cover observations are also a valuable data source for predictions with ... -
Remote sensing of chlorophyll-a in small inland waters
(University of Waterloo, 2022-01-26)Small inland waters (SIWs) – waterbodies smaller than 100 km2 – are the predominant form of lakes globally, yet they are highly subject to water quality degradation, especially due to harmful algae blooms (HABs). Space-borne ... -
Retrieval of Lake Erie Water Quality Parameters from Satellite Remote Sensing and Impact on Simulations with a 1-D Lake Model
(University of Waterloo, 2016-02-26)Lake Erie is a freshwater lake, and the most southern of the Laurentian Great Lakes in North America. It is the smallest by volume, the fourth largest in surface area (25,700 km2), and the shallowest of the Laurentian Great ... -
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 ... -
Toward Automated Ice-Water Classification on Large Northern Lakes Using RADARSAT-2 Synthetic Aperture Radar Imagery
(University of Waterloo, 2018-05-22)Changes to ice cover on lakes throughout the northern landscape has been established as an indicator of climate change and variability. These changes are expected to have implications for both human and environmental ... -
Towards automated lake ice classification using dual polarization RADARSAT SAR imagery
(University of Waterloo, 2018-01-18)Lake ice, as one of the most important component of the cryosphere, is a valuable indicator of climate change and variability. The Laurentian Great Lakes are the world’s largest supply of freshwater and their ice cover has ...
