Extensive development in south Etobicoke resulted in creeks historically viewed as a nuisance being buried, culverted or piped underground. However, creeks don’t just disappear, during large rainfall or snowmelt events. These buried creeks have been found to be a catalyst for flooding and reduce water quality because of reductions in storage and absorption of stormwater run-off over vegetated surfaces resulting in a ‘flashy’ response to stormwater. This project will investigate restoration options for the remnant portions of the lost creeks and investigate green infrastructure (i.e.
Northern Canada faces environmental changes from growing resource extraction and global warming, which make an understanding of baseline conditions critical. In the Dawson Range, Yukon, naturally elevated concentrations of uranium have recently been discovered in groundwater at levels that exceed federal water-quality guidelines. This region is also the focus of advanced mineral exploration and falls within traditional territories of several First Nations. Mining activities may enhance uranium mobilization through the generation of waste rock and tailings.
The proposed research project aims to develop and verify new technologies and numerical tools directed at six main research focus areas: 1. Orebody Knowledge, 2. Grade Management, 3. Cave Mine Design, 4. Integrated Cave-to-Mill, 5. New Measurement Technologies, and 6. Hazard Management. This project will also see the establishment of a multidisciplinary research network, the International Caving Research Network, to be directed at maintaining Canada’s competitiveness in the international mining industry.
The proposed project investigates the diagenesis of the lowermost Port au Port carbonates in Western Newfoundland. Few earlier studies suggested that the carbonates vary from lime mudstones of low energy to grainstones and rudstones of high energy shallow-shelf settings. The study will allow the reconstruction of full diagenetic history of the basin and factors that controlled the precipitation of cements and dolomitization that influenced the net rock porosity as well as the timing of precipitation of those cements during basin history.
The concern regarding the environmental impacts of climate change due to the consumption of fossil-fuels for our daily energy needs has notably increased over the past decade, resulting in a rapid increase of renewable energy implementation. The solar energy industry in particular has seen exponential increases in production worldwide.
Current Heavy Rare Earth Element (HREE) processing techniques are expensive, environmentally-challenging, and slow. Kinetic models predict that the rate of acid permeation of a mineral is the rate controlling step. Therefore, permeation rate controls the acid quantity and residency time of the mineral in the acid bath; impacting costs. Kinetic models are based on structural assumptions including the uniform distribution of elements within a mineral. This study proposes to employ atom probe tomography on the HREE-mineral gadolinite: an ore mineral in the resource at Strange Lake, Quebec.
As part of Envirosoil’s re-usable energy division in Nova Scotia and Newfoundland, drilling fluid waste product will be re-purposed as a potentially viable fuel supplement and additive in other industrial processes. The proposed research would look into viable options for reusing this material in a way that is commercially beneficial to the current operations, while also diverting the waste from landfills. The general objective of the proposed research is to better characterize the nature of the waste and how it can be safely pushed into the commercial market.
We have developed a model that simulates currents, nutrient distributions, and plankton growth in the Salish Sea. This project focuses on continued development of that model and its application to answering scientific questions. These questions include: 1) How much does the timing and amount of plankton growth vary from year to year, and what factors explain increases or decreases? 2) What is the impact of the timing and amount of plankton growth in the Salish Sea on food availability for salmon populations, particularly along migration routes?
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 method Emissions Attribution via Computational Techniques (ExACT), is a currently accepted truck-based leak inspection technology that can inspect hundreds of pieces of infrastructure daily, over large areas.
Visier Solutions Inc hopes to create a new standard for the measurement of employee diversity in organizations based on scientific research and measured baselines. With the help of the interns, this study will set a standard for the practical measurement of diversity in organizations as well as best practices in the analysis of metric results. The findings of this study will enrich our understanding of diversity and equal opportunity treatment of diverse groups in the corporate environment.
