Long-term hydrological dynamics of Canada’s largest watershed: Climate controls on water quantity of the Mackenzie River Basin
chercheur principal:
Année(s) de permis: 2020
Résumé: This licence has been issued for the scientific research application No.4705. The Mackenzie River Basin (MRB) is one of the largest cold-water, intact boreal ecosystems in the world and has unique Earth-system’s processes associated with sea ice formation, global circulation of deep ocean currents, carbon storage, and biogeochemical cycling. This unique global resource is also critical for supp...

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 (...

Permafrost, river, and groundwater inputs of trace elements and nutrients to the Mackenzie River estuary
chercheur principal:
Année(s) de permis: 2016
Résumé: The objectives are to measure a suite of trace elements and isotopes (TEIs) in the active layer and permanently frozen layer of permafrost cores sampled near the Mackenzie River, and to compare these concentrations to those observed in submarine groundwater discharge and Mackenzie River discharge in order to determine whether permafrost-associated TEIs are being transported to the coastal Arctic. ...
