Abstract: <p>A key knowledge gap in aeolian transport research concerns the adjustment of saltation processes to the extreme conditions found within high-latitude regions. A series of wind tunnel experiments were carried out under full climate control and over a wide range in humidity. Particle entrainment and transport within shearing flows of varied wind speed were monitored over beds of varied… more Full Text: i INVESTIGATION OF DYNAMICS OF PARTICULATE TRANSPORT UNDER VARYING CLIMATE CONDITIONS A thesis submitted to the Committee of Graduate Studies in partial fulfillment of the requirements for the Degree of Master of Science in the Faculty of Arts and Science …

Abstract: <p>This study examines the atmospheric (synoptic) controls on snowmelt and snow-free season carbon dioxide (CO2) fluxes at Daring Lake, Northwest Territories. Atmospheric circulation patterns were derived from 500 hPa geopotential height and classified using the self-organizing maps artificial neural network. Snowmelt timing was not found to be influenced by atmospheric circulation patterns… more Full Text: THE INFLUENCE OF ATMOSPHERIC CIRCULATION ON SNOWMELT AND CARBON FLUXES IN THE CANADIAN LOW ARCTIC A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts …

The WWTP exported 354.1 ± 24.7 billion microplastic particles, or 296.7 ± 39.4 kg of microplastics; of this, 85.7% of counts and 86.6% of mass was exported via biosolids. As such, microplastic loads in biosolids need to be reduced before… more

In this study, square metre scale field experiments (2021–2023) were conducted in Peterborough Ontario, Canada, each amended with kimberlite residues from Gahcho Kué Diamond Mine (Northwest Territories, Canada) or olivine powder at high… more
