Arctic Sea-ice extent is declining due to climate change. Wildlife, maritime operations and northern communities that depend on sea-ice for traveling and hunting are negatively affected by its decline. Monitoring sea-ice thickness is an important tool to help in decision making in Arctic regions but, due to the snow covering the sea-ice, remote sensing’s sea-ice […]

The connection between climate change and terrestrial ecosystems has long been a key challenge in global change research. Climate change and hydroclimatic disturbances will impact the structure and functioning of these ecosystems. Therefore, studying their responses to disturbances at different scales is crucial for contributing to ecosystem management, mitigation, and adaptation strategies. This study seeks […]

L’étudiant étudiera l’influence de la salinité sur l’efficacité de traitement de l’azote ammoniacal présents dans les effluents miniers par les microbulles d’ozone. Cette étude permet d’avancer l’identification des facteurs qui peuvent influencer ce type de traitement qui a montré son efficacité pour le traitement des eaux minières dans des conditions climatiques froides.

The City of Calgary has identified four locations along the Elbow River where erosion may be(come) of concern for the safety of the nearby urban areas. This project will study the change in the shape of the Elbow River over time and in different conditions in order to enhance the understanding of its behaviour. This […]

Le traitement du drainage minier (DM) est une activité clé pour la durabilité des opérations minières. Idéalement, un système de traitement passif devrait être conçu pour fonctionner pendant nombreuses années, sans nécessiter une maintenance majeure. Des études récentes ont montré l’efficacité de ce système pour les sites miniers abandonnés et éloignés en voie de restauration. […]

Atlantic salmon (Salmo salar) are anadromous salmonids; they inhabit both marine and freshwater habitats during distinct stages in their life cycle. Anadromy allows Atlantic salmon to play a vital role in connecting freshwater and marine ecosystems by facilitating nutrient transport and trophic interactions. This project will examine the stable isotope and lipid composition of Atlantic […]

Our goal is to achieve environmental sustainability while facing severe resource constraints (including a lack of financial resources, skilled labor, and available power sources) by using innovative and non-conventional technologies. Agricultural products have been demonstrated to be an effective alternative to conventional treatment systems for the adsorption-based removal of hazardous heavy metals such as chromium […]

Les fleuves représentent l’une des plus grandes ressources naturelles, sociales et économiques au monde. Figures emblématiques du cycle de l’eau, les fleuves jouent un rôle de premier plan dans la régularisation du climat, le développement urbain, l’agriculture et les échanges économiques. Par exemple, le fleuve Saint-Laurent draine à lui seul plus d’un quart des réserves […]

While rivers are an important and highly visible pathway for freshwater to reach the ocean, another less noticeable, but also important, pathway is the discharge of groundwater from the sea floor. This phenomenon, known as Submarine Groundwater Discharge (SGD), is significant to the coastal ocean because it can carry water-based nutrients and pollutants into the […]

Pharmaceuticals are considered intractable and easily transported into the water system. As a result, wastewater treatment plants (WWTPs) are unsuccessful in completely removing these contaminants. The successful removal of these pharmaceuticals depends on the removal and purification technologies that are being used and the physiochemical properties exhibited by these pharmaceuticals. Recent research from Canada concludes […]

Keeping the lights on for over 4 million people across the province takes a lot of talented people doing many different jobs, from working deep in a generating station, atop a power pole, or behind a desk. We’re working on upgrading transmission lines, building new substations, and investing in our hydroelectric generation facilities. It’s our […]

The climate warming currently affecting the Arctic is two to three times faster than anywhere else, with profound consequences for natural ecosystems and communities. Notably, thawing permafrost remobilizes organic matter (previously trapped in the soil) that underlies the production of greenhouse gases such as carbon dioxide and methane, which in turn helps amplify the ongoing […]
