Assessing the role of small-scale structures in controlling auriferous fluid flow: Nadaleen trend, Yukon.

Carlin-type gold deposits (CTGDs) are large, high-grade gold deposits named after the world renowned occurrences in Nevada. Despite their economic importance, agreement on how they formed is still lacking. We are undertaking an integrated geological and geochemical study of CTGDs in the Nadaleen trend, Yukon, to better define the hydrological regime that controlled their formation. The proposed Mitac internship will form part of the overall study – performing detailed analysis of small scale features that were potential fluid flow pathways for hot gold-bearing hydrothermal fluids.

Experimental testing of employing large grains as a bank erosion mitigation technique

Traditional engineering approaches to stabilizing stream’s (e.g. dams and cemented banks), typically alter a stream’s natural function and are expensive to maintain. Using large grains naturally found in a stream, could provide a way to stabilize the channel’s banks while still allowing natural system movement. To test if treatments of large grains could be used in river engineering projects, a physical model will be built. The large grain treatments will be subjected to environmental conditions typically experienced by river engineering projects.

Characterizing wetlands of different restoration ages in central Alberta using drone-based information (an extension to current Mitacs project: IT10213)

Wetlands provide important ecosystem services to human communities, such as groundwater recharge, storing floodwater, and supplying fishery resources. In Alberta, wetlands cover ~21% of the province, forming one of the Canada’s largest wetlands reserves; however, many of these wetlands have been impacted or lost through human activities. Over the past 30 years, there have been efforts made by the government and partner agencies to restore wetlands, but little is known about the rate of recovery and the state of these restored wetlands, relative to a natural reference condition..

Hey Neighbour! Evaluation and Understanding Social Connections and Engagement

The Hey Neighbour! pilot program evaluation intends to draw conclusions about the potential of social policy interventions into urban neighbourhoods. First, we will review the multidisciplinary research trends and approaches related to the question of improving social quality in urban neighbourhoods and communities. This will include review of the terminology, definitions of related terminology, overlapping usages across disciplines, co-citations, and different methodological approaches in the past generation, in the scholarly literature.

Assessment of processes controlling naturally elevated uranium and arsenic concentrations in groundwater and surface water in the Dawson Range, Yukon, Canada

Northern Canada faces great changes from growing resource extraction and global warming, which make a timely understanding of baseline environmental conditions critical. In the Dawson Range, Yukon, naturally elevated concentrations of uranium and arsenic have recently been discovered in groundwater at levels that are susceptible to cause toxic effects in humans and wildlife. This region is also the focus of advanced mineral exploration and falls within traditional territories of several First Nations.

Strategic BC Salmon Health Initiative: effects of pathogens on the health and conservation of BC’s Pacific Salmon

B.C.’s Pacific salmon are in decline yet the causes are not clear. The role of disease in declining productivity is poorly understood but is potentially an important factor especially given recent controversies involving salmon farms and disease transmission to wild salmon. We have recently collected quantitative data on 47+ viral, bacterial, fungal, and protozoan pathogens in >16,000 out-migrating juvenile sockeye, Chinook and coho salmon and 4,500 salmon from farms culturing Atlantic and Chinook salmon.

Integration of microbiological and geochemical tools for de-risking oil and gas exploration along the Scotian Margin

This Mitacs project will enable two MSc students the opportunity to work with the Offshore Energy Research Association and their partners with the Nova Scotia Department of Energy to produce an ArcGIS product and seismic-based model of seep architecture for petroleum exploration of the offshore Nova Scotia margin. These projects will relate newly created genomic and lipidomic data that is expected to help de-risk offshore exploration efforts. The Interns will use these data to produce maps and 3D models of the seeps

Mapping blood brain barrier permeability- towards a novel biomarker for psychiatric disorders

Research into brain diseases has until recently focused on neurons, but in the last several decades, blood vessels have taken a new spotlight. When blood vessels are damaged, substances can leak from the blood into the brain. Such leak can affect memory and mental health, but surprisingly, its impact on psychiatric disorders has yet to be studied in detail, largely due to lack of technology to map leaky blood vessels in living patients.

Clay Binding of Gravel Roads

Throughout much of northern and rural Canada roads are constructed of unpaved gravel aggregate. They are expensive to maintain, environmentally problematic and degrade quickly. We are developing a solution to this problem by using locally derived materials rich in reactive clays. With the addition of catalysts and polymeric agents, we cause the fine clay materials to bind the aggregate strongly. Simply put, we are taking advantage of and manipulating the natural properties of clays, and causing them to act like a cementing agent.

A stakeholder analysis of outreach opportunities to support low-carbon smart transitions for transit modernization

Transportation that uses green energy is environmentally friendly and helps to reduce greenhouse gas emission. But there is a tension between the stakeholders, policy makers and public on their economic return, policy implementation and perception on innovation in technology in transit respectively.
