Hydrothermal gold deposits contribute a noteworthy fraction of the world’s gold endowment. These deposits are characterized by the widespread occurrence of hydrothermal alteration formed during the interaction of hydrothermal fluids with the wall rocks, which induces important mineralogical and geochemical changes to the original rock. The main objective of this research is the detail characterization […]

I will be focusing my study on a small tidal marsh called Frenchies Island within the South Arm Marshes of the Fraser River, which has become overrun with an invasive species of cattail. Frenchies, like many tidal marsh islands has had a dike constructed around its perimeter and has therefore been cut off from the […]

Study of the core of ancient mountain belts is key to the understanding of current tectonic processes. In Canada and Sweden, the Grenvillian and Sveconorwegian orogenies are the relict of a major tectonic event, similar to the continent-continent collision between India and Eurasia. In both locations, a major tectonic boundary i.e. the Allochthonous Boundary Thrust […]

Les forêts urbaines d’aujourd’hui sont confrontés aux changements globaux, notamment l’augmentation de la fréquence des événements climatiques extrêmes (sécheresses, inondations, etc.) et l’arrivée d’espèces exotiques (maladie de l’orme, agrile du frêne, etc.), et subissent donc de lourdes pertes associées à ces stress. Les conséquences de la réduction de la canopée peuvent être dramatiques d’un point […]

Climate change is shifting the distribution of fish stocks towards areas with cooler environment, generally in higher latitude or deeper water. Such shifts threaten to increase the amount of conflict over resources as stocks move freely in ocean waters crossing human-made management boundaries. Anticipating these shifts can help identify appropriate mechanisms of joint-management and contribute […]

where the best sites, and combinations of sites are, is critical to facilitate private investment in wind electricity. The proposed research with Brookfield Renewable Energy Partners L.P. will determine the most desirable locations for large-scale wind farm deployment, as well as the cost of electricity supplied by such farms to a selection of Canadian demand […]

Ce projet vise a effectuer une analyse spatia Ie de la diffusion des epidemies du principal ravageur des coniferes en Amerique du Nord: la tordeuse des bourgeons de I’epinette, pendant tout Ie 20e siecle. La defoliation par cet insect entraine une reduction caracteristique de la croissance, visible dans Ie cerne de croissance des arbres hotes […]

Canada has set a goal to reduce methane emissions in the upstream oil and gas sector by 45%. An updated regulation, proposed to implement on January 1st, 2020, will require triannual leak inspections of upstream infrastructure. Traditional leak inspection methods have a high cost per inspection and require unfeasible man-hours in the field. Alternative LDAR […]

Geologists are accustomed to studying geological processes, often using our knowledge of physics, chemistry, and biology to locate mineral deposits. However, a sub-discipline within geology, isotope geochemistry, is able to apply its expertise to not only locating mineral deposits, but also solving a wide variety of other problems, ranging from detecting doping in sport to […]

Le socle rocheux de l’île de Montréal est constitué de calcaires déposés sur la marge continentale de Laurentia, il y a 450 millions d’années, qui bordait alors un océan où existait une intense activité volcanique. La stratigraphie de ces formations rocheuses est bien documentée, mais il est encore difficile de déterminer précisément la position stratigraphique […]

The research aims to examine the amount and type of microplastics in wastewater streams entering the Ottawa River. As wastewater treatment has been identified as one of the main conduits of microplastics to freshwater environments, the research will sample both wastewater effluent and combined sewer overflows to get a better understanding on how many, and […]

Afin de réduire son empreinte environnementale, l’entreprise Nemaska Lithium souhaite revaloriser les résidus produits par le traitement de leur minerai de spodumène, un minéral riche en lithium, afin d’éviter leur entassement. Dans cet optique, différentes voies de valorisation ont été envisagées, incluant, entre autres, la fabrication de verre et vitrocéramique lithié, l’utilisation dans le ciment […]
