Biodegradation of Dissolved Organic Matter

Water is vital for life; it is a resource we interact with daily and rely on implicitly. Our reliance on water resources is why water pollution is a global concern. One risk to water quality is elevated levels of toxic trace metals. While metals occur naturally in aquatic environments, human activities can increase natural concentrations […]

Variational integrator for the RSW equation on the sphere under local uncertainty

Numerical simulation is a cornerstone of modern science and industry, and is used in many facets of our everyday lives. While many of us are familiar with short-term weather forecasting, substantially more computational effort is dedicated to longer-term simulations of the Earth’s ocean and atmosphere, for climate and other reasons. In such simulations, certain properties […]

Efficacité du débit réservé à préserver le saumon atlantique juvénile et ses habitats

L’exploitation de la centrale hydroélectrique Romaine-1 cause sur la rivière Romaine des fluctuations du débit susceptible d’entraîner le déplacement des saumons juvéniles en dehors de leurs habitats préférentiels. Il est donc essentiel de déterminer si le mode de gestion actuel des débits permet aux saumons juvéniles de se maintenir dans leurs habitats. Pour étudier la […]

Cryosphere Reduction Impacts on Arctic Seabird Ecology

Arctic temperatures are increasing twice as fast than the global average. In fjordic ecosystems of Svalbard, the Atlantification, the process leading to warmer conditions in the area impose new challenges to Arctic living community. Those changes alter cryosphere regime (i.e., ice component covering the surface) and associated species habitats. The black-legged kittiwake is a predator […]

Marine Technology Research

In this project I will be working with Aalto university’s Marine Technology research group at the Aalto ice tank. The purpose of such an ice tank is to explore the function of arctic marine structures in pack ice conditions. For example, this could include structural testing of oil and gas facilities or model testing of […]

Simulation du transport de nitrate par l’écoulement d’eau dans les terrains agricoles drainés

Les drains souterrains sont des tuyaux perméables installés dans le sol afin d’extraire l’excès d’eau souterraine des terrains agricoles humides dans le but d’améliorer la production alimentaire. Lorsque l’eau souterraine s’écoule vers ces drains, le nitrate utilisé comme fertilisant est dissout dans l’eau et est rapidement déchargé aux rivières et à l’océan. Cela cause des […]

Structural Inequality, Resistance, & the Future of a Continent: Examining Colonialism’s Toxic Legacies

Last year, the world’s leading health researchers found toxic pollution to be the greatest cause of disease and premature death in the world today. However, while the findings acknowledge that deaths caused by toxins to be most prevalent among marginalized groups, there is no mention of socio-historical structures in producing these toxic patterns. Through this […]

Quantifying the value and risk of restoring wetland habitats in agricultural landscapes

Wetlands provide critical habitat and valuable ecosystem services. Land use conversion in Ontario, however, has led to substantial wetland loss. The restoration of wetlands on agricultural properties has the potential to offset wetland loss, yet these wetlands are also susceptible to contamination by pesticides. Our research will therefore establish: (1) to what degree restored wetlands […]

Nutrient balances (phosphorus and nitrogen) in Lake St. Charles, Quebec, and the evaluation of effectiveness of remediation scenarios for nutrient reductions on the lake’s water quality

Lake St. Charles is the primary drinking water reservoir of Quebec City, Canada, providing water to about 300,000 people. Over the past decade, several occurrences of blue-green algae (cyanobacteria) bloom have been recorded, affecting the quality of water in this strategic reservoir. Evaluation of observed data collected over the past decade indicates that the water […]
