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: This research project has two primary scientific goals which include: 1) Relating ground truthed snowpack data to passive microwave data obtained from satellites through the winter months. This will assist in formulating a empirical relationship between the two datasets which is necessary to improve satellite monitoring of snow water equivalent. 2) Determining the relative importance of snowmel...

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: The objective of the research is to determine the water cycle processes in lakes and streams affecting Baker Creek and similar streams, and more generally to understand how small scale processes influence those of larger areas. Field studies at Baker Creek, a typical Canadian Shield stream that drains ~130 km2 into Great Slave Lake, will focus on the spring melt and summer seasons. Existing i...

Summary: This study is a continuation of a project that began in 2001. The researchers are studying the flow and storage of water in the Scotty Creek watershed. The data they collect will help them to create a model that will do a better job of estimating the volume and timing of basin runoff in wetlands in discontinuous permafrost terrain. The information they have collected so far suggests that peat p...

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....

Licensed Year(s): 1994 1993
Summary: This on-going study attempts to find out how permafrost affects the groundwater, streamflow and levels of water in wetlands. Measurements such as soil moisture, rainfall, ground and air temperatures, and water level will be taken. This research will help to determine how climatic change affects permafrost and water bodies in the Arctic....

Licensed Year(s): 1993 1990
Summary: As part of an ongoing study in which field work was conducted in 1989 and 1990, this year's work will involve a study of the effects that snowdrifts can have on blocking the movement of meltwater in the McMaster River during the spring. Snowdrifts located at several sites along the river will be monitored to determine how they can alter the river's course, how these drifts are eventually broken d...
