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. ...

The Nature and Origin of Ground Ice in the High Arctic and Icing as a Hydrologic Component of Northern Drainage Basins
chercheur principal:
Année(s) de permis: 1994 1992 1991 1990 1988
Résumé: The researchers will gain a better understanding of permafrost conditions of the study area and the environmental conditions under which permafrost formed and evolved. They will also investigate icings and icing processes, since icings are a hydrologic phenomenon and their occurance has implications for recharge and runoff of drainage systems and water resource management....
