The use of geophysical imaging for improved monitoring and management of saltwater intrusion

Saltwater intrusion poses a high level of risk to fresh water resources in coastal communities throughout Canada and the world. Saltwater intrusion is driven by withdrawal of groundwater from aquifers, and by rising sea level. The goal of this work is to demonstrate the usefulness of geophysical methods (electrical resistivity tomography and distributed temperature sensing) for improved monitoring and management of saltwater intrusion at the basin scale. These methods, which are similar to those used in medical tomography, allow for mapping the distribution of saltwater intrusion.

Modelling and Imaging of Fluids in Fractures

Hydraulic fracturing is a process where fluids are injected in high pressure into wells and fracture the rocks. This process is the driver for shale gas extraction and therefore its efficiency plays a major role for unconventional oil recovery. One of the key questions in such a process is the extent that the pressurized fluids penetrate the reservoir. The goal of this research is to investigate the use of electromagnetic methods for the imaging, identification and control of this process.

Émission de gaz à effet de serre par les sols suite à l’application de cendres de bois dans les érablières estriennes

L’application de composés alcalinisants tels que la chaux ou la cendre est de plus en plus envisagée dans les érablières du Québec afin d’améliorer le statut acide-base du sol et la nutrition des forêts. Il est possible, cependant, que ces composés provoquent un accroissement de l’activité microbienne du sol, ce qui pourrait augmenter la production de gaz à effet de serre par les sols forestiers.

Mineralogy and geochemistry of selected granitic pegmatites in Uganda

Pegmatites are important sources of several rare elements which are essential for development of modern technologies. The pegmatite deposits in Uganda had been explored and mined until the early 1970’s. At present, they are being re-evaluated and exploration for new deposits is ongoing. Auranda is seeking to establish models for mineral production based on certified, conflict-free production and trading chains.

Creative Funding Opportunities for Cultural Space Projects: Lessons for Toronto

This research project investigates public and private investment ideas and strategies for local culture and heritage projects, with an emphasis on lessons for Toronto, Canada. The study will identify emerging trends and developments in the areas of urban planning, heritage preservation, cultural investment and local governance. The research will be based on current thinking from academic literature, public policy, professional expertise, and first-hand accounts of those working in the philanthropic and charitable giving sectors.

Improving stream tracer gauging techniques

Stream discharge, a measurement of the volume of water passing a location along a stream, is an essential variable in many engineering and scientific projects. Discharge can be measured by injecting tracer material (such as common table salt or coloured dyes) into a stream and observing how the material mixes in the stream channel. For many streams, tracer gauging studies are the only reliable and safe method to determine discharge, yet many uncertainties exist in the experimental procedure.

Géologie et genèse des veines de minéralisations aurifères de la propriété Belleterre de Les Mines JAG Ltée, Abitibi Témiscamingue, Québec

Le présent projet de stage porte sur la propriété Belleterre de Les Mines JAG Ltée qui est située à environ 150km au sud de Rouyn Noranda et 70km à l’est de Ville-Marie, c’est un site aurifère en contexte volcano-sédimentaire, avec zones de déformation et mise en place de veines aurifères et de formation de fer au faciès oxydés. De nombreux intrusifs recoupent les roches volcaniques et certains sont spatialement associés à la minéralisation aurifère.

Détermination des sites de fixation des éléments traces métalliques dans les sédiments de lac

L’approche conventionnelle de l’interprétation des résultats de géochimie d’exploration implique généralement des méthodes statistiques variablement sophistiquées. La faible capacité prédictive de la méthode est notoire. De plus, la littérature demeure sans réponse quant aux sites de fixation préférentiels des métaux dans les sédiments de lac. Dans le but d’éventuellement relier la source aux enrichissements secondaires, IOS Services Géoscientifiques Inc (entreprise partenaire) aimerait déterminer les sites de fixation préférentiels des métaux dans les sédiments de lac.

Contributions méthodologiques aux études d'impacts des projets de mines d’uranium au Québec

Depuis 2006, le gouvernement du Québec a réorienté sa politique minière pour promouvoir l’exploration de l’uranium dans le nord québécois. Cependant, les manifestations par des groupes sociaux se sont multipliées résultant ainsi en divers blocages de projets d’exploration de l’uranium (Sept-Îles).

Riverine feature extraction from high-resolution imagery

Physical infrastructure designed and developed to enable this growth has been in place for 50 years or more, and an increasing proportion has reached the end of its design life. Taking dams for example, while the Canadian case is less well documented, 85% of U.S. dams will be >50 years old by 2020. In particular, decayed riverine infrastructure (e.g., dams, levees, bridge and pipeline crossings, etc.) has significant implications for public safety, economic and environmental health.
