    Les infrastructures de transport est essentielle au maintien et à l'expansion des activités sociales et économiques dans les régions circumpolaires. À mesure que le climat se réchauffe, la dégradation du pergélisol sous les remblais a entraîné de graves dommages structuraux à la route, entraînant une augmentation importante des coûts d'entretien et une réduction de la durée de vie des infrastructures. Pendant ce temps, l'advection de chaleur déclenchée par les écoulements d’eau souterrains peut altérer le bilan énergétique du remblai et du pergélisol sous-jacent et modifier le régime thermique des remblais routiers. Cependant, peu de recherches ont été effectuées pour comprendre la synergie entre les processus thermiques de surface et souterrains des remblais routiers des régions froides. L'objectif de cette recherche était de comprendre les interactions thermiques entre l'atmosphère, le remblai routier, les écoulements d’eau et le pergélisol dans le contexte du changement climatique. Cette base, de connaissances est nécessaire pour la conception technique, l'entretien des routes et l'évaluation de la vulnérabilité des infrastructures. Les travaux de recherche ont permis de développer de nouvelles méthodes d'analyse thermique pour caractériser et identifier le rôle de l'advection thermique sur le changement de température d'un remblai routier expérimental au Yukon (Canada) en termes d’intensité, de vitesse et de profondeur de l'impact thermique. Les résultats montrent que l'augmentation de la température due aux flux de chaleur advectifs déclenchés par l’écoulement d'eau peut être jusqu'à deux ordres de grandeur plus rapide qu'en raison du seul réchauffement atmosphérique. La recherche a ensuite présenté un bilan énergétique de surface pour quantifier la quantité d'énergie entrant dans le centre et la pente du remblai avec des épaisseurs et des propriétés de neige variables. Le tout a été appuyé par des observations géothermique de plusieurs années et une grande quantité de données météorologiques. Les résultats illustrent que le bilan énergétique de surface est principalement contrôlé par le rayonnement net et moins par le flux de chaleur sensible. Le flux de chaleur transmis à la pente du remblai diminue de façon exponentielle avec l'augmentation de l'épaisseur de la neige et diminue de façon linéaire avec l’installation du couvert de neige et la longueur de la période d’enneigement. De plus, un modèle de bilan énergétique de surface et un modèle cryohydrologique entièrement couplé ont été développés pour étudier l'impact thermique de l'advection de chaleur associée à l'écoulement de l'eau souterraine sur le dégel du pergélisol et le développement de taliks (c.-à-d. zone perpétuellement non gelée dans les zones de pergélisol). Le modèle couplé a réussi à reproduire la tendance à la hausse du plafond du pergélisol (erreur absolue moyenne <0,2 m) au cours de la période 1997-2018. Les résultats montrent que l'advection de chaleur a fourni une source d'énergie supplémentaire pour accélérer le dégel du pergélisol et a doublé le taux d’augmentation de l’épaisseur de la couche active 0,1 m·a-1 à 0,19 m·a-1, par rapport au scénario où aucun écoulement d'eau ne se produit. Le talik s'est initialement formé et développé en fonction du temps sous l’effet combiné des écoulement d’eau, de l'isolation de la neige, de la construction de la route et du réchauffement climatique. Le débit d'eau souterraine a relié des corps isolés de talik et a amené le remblai de la route dans un état thermique irréversible, en raison de la rétroaction de l'eau liquide (effet de chaleur latente) piégée dans le talik. Ces résultats montrent l'importance de l'advection de chaleur induite par l'écoulement d'eau sur le régime thermique de la sous-couche (c.-à-d. la couche de matériau de remblai) et du sous-sol (c.-à-d. le matériau natif sous un remblai) du remblai lorsque le remblai routier intercepte le drainage local. De plus, les résultats obtenus soulignent la nécessité de coupler les processus thermiques de surface et souterrains dans le but d'évaluer la stabilité thermique des routes subarctiques. Transportation infrastructure is crucial to maintaining and expanding the social and economic activities in circumpolar regions. As the climate warms, degradation of the permafrost causes severe structural damages to the road embankment, leading to large increases in maintenance costs and reductions in its lifespan. Meanwhile, heat advection triggered by mobile water flow can alter energy balance of the embankment and underlying permafrost and modify the thermal regime of road embankments. However, little research has been done to understand the synergy between surface and subsurface thermal processes of cold region road embankments. The overall goal of this research was to elucidate thermal interactions between the atmosphere, the road embankment, mobile water flow, and permafrost within the context of climate change. This knowledge is needed for engineered design, road maintenance, and infrastructure vulnerability assessment. The research first used new thermal analysis to characterize and identify the role of heat advection on temperature change of an experimental road embankment, Yukon, Canada in terms of magnitude, rate and thermal impact depth. It shows that soil temperature increase due to advective heat fluxes triggered by mobile water flow can be up to two orders of magnitude faster than due to atmospheric warming only. The research then presented a novel surface energy balance to quantify the amount of ground heat flux entering the embankment center and slope with varying snow depth and properties, supported by multi-year thermal and meteorological observations. My results illustrate that the surface energy budget is mainly controlled by net radiation, and less by the sensible heat flux. The ground heat flux released at embankment slope exponentially decreased with the increase of snow depth, and was linearly reduced with earlier snow cover and longer snow-covered period. A fully integrated surface energy balance and cryohydrogeological model was implemented to investigate the thermal impact of heat advection associated with subsurface water flow on permafrost thaw and talik (i.e., perennially unfrozen zone in permafrost areas) development. The integrated model successfully reproduced the observed increasing trend of the active layer depth (mean absolute error < 0.2 m) over the 1997-2018 period. The results show that heat advection provided an additional energy source to expedite permafrost thaw, doubling the increasing rate of permafrost table depth from 0.1 m·a-1 to 0.19 m·a-1, compared with the scenario where no water flow occurs. Talik formation and development occurred over time under the combined effect of subsurface water flow, snow insulation, road construction and climate warming. Subsurface water flow connected isolated talik bodies and triggered an irreversible thermal state for the road embankment, due to a local feedback mechanism (latent heat effect) of trapped, unfrozen water in talik. These findings elucidate the importance of heat advection induced by mobile water flow on the thermal regime of embankment subbase (i.e., a layer of fill material) and subgrade (i.e., the native material under an embankment) when the road embankment intercepts the local drainage. Furthermore, the obtained results emphasize the need to couple surface and subsurface thermal processes to evaluate the thermal stability of sub-Arctic roads.

    Climate change is currently the most pressing environmental concern, especially for northern climatic regions like Canada. Climate change impacts a wide variety of environmental factors that in turn alter vegetative processes, like that in cereal grains. As grain kernels weaken due to environmental stress it becomes increasingly susceptible to infection. This review will detail one such type of infection produced by fungi: mycotoxins. Mycotoxins come in several varieties of which five will be examined in this review: aflatoxin, ochratoxin, deoxynivalenol, fumonisins, and zearalenone. Mycotoxins cause many different types of illnesses ranging from gastrointestinal disruption to death. Since mycotoxins affect plants, all consumers are at a possible risk of infection, with the most vulnerable members of the population being children, due to their small body size. Therefore, this review will assess the impact of climate change on mycotoxin contamination in cereal grains and the implications for children’s health in a Canadian context.

    With continually increasing concern over anthropogenic carbon dioxide emissions and their effect on global climate, the search for alternative fuels, especially for mobile applications such as in vehicles, is of immediate concern. Herein, research towards hydrogen as an alternative energy carrier is discussed; first, with the investigation of “hybrid” hydrogen storage systems that are meant to provide hydrogen for a fully fuel cell powered vehicle via a chemical reaction; and second, that of a thermally regenerative fuel cell system (TRFC) to partially supplant the energy needs of transport trucks by harnessing engine waste heat. Hybrid storage systems are comprised of a heterocyclic carrier that undergoes endothermic hydrogen release (indoline) and an organic hydride that undergoes exothermic release (amine boranes). Different embodiments are considered, varying in the mechanism of exothermic release (thermolysis vs. hydrolysis) and the mode of combination (physical vs. chemical). A thorough investigation into the effect of catalyst, sterics and temperature on the heterogeneously catalyzed dehydrogenation rate of N-heterocycles was executed. A number of trends with respect to the catalyst identity and the level of steric protection around the nitrogen atom were observed. The study towards a TRFC involved an investigation of the heterogeneous hydrogenation of benzylic ketones. Screening of a myriad of different catalysts was performed, including those with various supports, metals and modifications, and the examination of how both the sterics and electronics of the ketone affect the hydrogenation rate. A rapid hydrogenation at relatively low metal loadings and hydrogen pressures with extreme selectivity (>99.9%) is required. To date, however, such a combination has been elusive. The best selectivity was obtained with commercial Pd/SiO2 (99.99%), yet at a low conversion of 6%, after 1 h under 1 atm of H2 at 100 ˚C. In addition to the poor conversion, SiO2 is not electronically conductive and is therefore not fit for this application. The best viable catalyst, then, was a Pd/Vulcan XC-72 (carbon) catalyst made by the author with an observed 14% conversion and 98% selectivity under the same conditions. However, trends in activity and selectivity with respect to the catalyst and ketone have been characterized herein.
