Comparing the snow depths and densities of different habitats in the Beaufort Delta region
chercheur principal:
Année(s) de permis: 2018 2017
Résumé: The objective is to compare differences in snow depth, density and morphology of a heavily forested site and a tundra site. The Principal Investigator (PI) will study the effect landscape (forest vs. tundra) has on seasonal snow pack evolution and physical properties (density, temperature, snow grain morphology, and stratigraphy) of the snowpack. These results will be compared to historical data (...

Résumé: 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...

Vegetation Response to Global Warming in the Mackenzie River Basin: Interations Between Northern Boreal Forests, Wetlands and Regional Hydrology
chercheur principal:
Année(s) de permis: 1992
Résumé: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...

Snowmelt Runoff/Chemistry in High Latitude Permafrost Basins

Résumé: The Researchers will study the role of the snowcover in controlling both streamflow and the movement of solutes/nutrients/pollutants through both tundra and forested ecosystems. Computer models will also be developed to predict the distribution and properties of snow, its melt and runoff during the spring period, and the release of solutes/nutrients/pollutants from the snow....
