Summary: This licence has been issued for the scientific research application No.5496. The objectives of this project are: 1) to develop improved understanding of, and ability to predict, snowcover formation and melt, as well as stream discharge in northern regions; 2) consider the integrated effect of climate on vegetation, snow, permafrost, streamflow, and lakes; and 4) develop improved predictive mod...

Summary: The primary objectives of this study are to: 1) understand and explain the role of snow microstructure in terms of the radar backscatter and phase response in this environment 2) to evaluate the efficacy of differential synthetic aperture radar (dInSAR) for snow accumulation estimates at C-band, and 3) to evaluate the optimal approach to estimating snow water equivalent using radar from this site....

Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...

Summary: As part of a long-term study, the researchers will look at the role of the snowcover in controlling both streamflow and the movement of solutes/nutrients/pollutants through both tundra and forested ecosystems. Work will consist of measuring amounts and distribution of snow, streamflow and release of solutes/nutrients/ pollutants in two river basins at the end of winter....

Summary: The researchers will continue their study, initiated in 1990, on the geological and hydrological processes which contribute to valley formation in the subarctic and arctic. Data will be collected on various aspects of water runoff and sediment content. This data, along with long-term environmental data collected by Environment Canada, will contribute to our knowledge about valley formation....

Summary: Snow samples will be collected from approximately 30 sites across the NWT and Yukon in the spring of the year. This annual snow pack sample will allow an estimate of the quantity of organic contaminants that have been deposited over the winter season. To better understand the fate of these contaminants in the High Arctic, the researchers will undertake an intensive small basin study on Cornwallis ...

Principal Investigator: Anderson, John C.
Licensed Year(s): 1978
Summary: 1. To conduct hydrologic studies with regard to highway construction. Measurements of pre-melt snow, ice covers, snow melt, rainfall, stream discharge, suspended sediment concentrations and water temperature in rivers will be taken. 2. Some aerial and road based reconnaissance will also be undertaken....
