Sound localization involves the triangulation of the location of a sound source by recording it on multiple microphones. One potential application of sound localization technology is to monitor the movements of vocalizing animals passively, without the need for a human observer. This project aims to further develop and test sound localization technology, then to apply the technology to monitor the movements and behaviours of birds in Alberta’s oilsands region in the vicinity of inactive well pads in burned and unburned areas.
Rockfalls and landslides are a common hazard throughout Canada and have a significant impact on transport corridors, infrastructure associated with natural resources, and in public areas. The ability to determine the potential for slope failures is often limited either by the lack of a detailed assessment of the slope, or by the understanding of the processes driving failure. The latter is particularly limiting when considering small-scale movements, which potentially indicate subsequent, larger failures.
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 Canadas 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..
The research problem to be addressed is the diversion of organic waste from landfills which, currently, in addition of using the limited space available, generate polluting leachate and greenhouse gases. On the other hand, landfilling organics represent a wasted opportunity to recover valuable chemical and energy resources. The internship will focus on the investigation of the potential of pyrolysis technology to address such problems, by creating opportunities to convert the waste into value-added chemicals and fuels.
The research objectives are to better understand the limitations of a new particle sizing system in terms of accuracy on particle size, of accuracy on size distribution, of accuracy on particle concentration and finally of size dynamic range. During the research project, the sources of the limitations will be identified and improvements to the technology will be proposed. State-of-the-art equipment for the generation of particles with known sizes and concentrations available at the University of Alberta will be used for the characterization of the technology.
The Liard River Watershed covers 275 000 square kilometres in Northeastern British Columbia. This vast area is increasingly being developed for its underlying shale gas resources using hydraulic fracturing (fracking). However, there are few studies investigating the environmental impacts of such activity in this vast area. Fossil fuels and freshwater are two of Canadas most important natural resources, and therefore an understanding of the water-energy nexus is paramount.
Ecomuseums are primarily community-based endeavors that respond to local needs while concentrating on sustainability. They help guide and develop democratic projects that focus on connections to local history and heritage, which include local physical geographic features, natural resources, natural habitats and agricultural practices. This research concentrates on creating an educational program to be delivered on a local conservation easement in southern Saskatchewan.
Nearshore marine ecosystems are undergoing change, with ecological, economical and cultural ramifications. Yet, we lack empirical understanding and observation of the nature of this change, over long periods of time and across continental coastlines. Additionally, the drivers of change in coastal systems are numerous: climatic forcing, predator recovery, and development of foreshore areas, amongst others. As such, deciphering the agents of change remains challenging.
While we enjoy the modern convenience brought by a multitude of man-made organic chemicals, such as surfactants and flame retardants, the exposure to these compounds, some of which are bio-accumulative, persistent and even toxic, may endanger our health. Humans are exposed to chemicals in consumer products during both product use in the indoor environment (near-field exposure), and consumption of contaminated animal- and vegetable-based foods (far-field exposure).
Assessment of the effects of earthquakes on rock slopes requires detailed measurements both before and after the shaking. However, at present, there is a lack of high resolution data that enables this, partly as it is unusual to have good data from prior to earthquakes.
