Principal Investigator: Rudolph, David
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5617. Within the Central Mackenzie Valley of the Northwest Territories (NWT), discontinuity and rapid change within the regional permafrost is anticipated to be influencing landscape, hydrology, habitat and ecosystem characteristics along with presenting challenges for the stability of constructed infrastructure. Mapping t...

Licensed Year(s): 2016
Summary: 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. ...

Principal Investigator: Woo, Ming-ko
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....

Principal Investigator: English, Michael C
Licensed Year(s): 1994 1992 1991
Summary: The researchers are interested in understanding how physical factors (snowmelt, rainfall, solar radiation) play a role in thawing the upper part of the ground each year during the spring and summer. Instruments in the ground will collect data that will estimate how much energy (from the sun) is entering into and melting the frozen ground. Other instruments will measure snowmelt, rainfall and the...

Principal Investigator: Pollard, Wayne H
Licensed Year(s): 1994 1992 1991 1990 1988
Summary: 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....

Principal Investigator: Haertling, Joachim
Licensed Year(s): 1987
Summary: To assess the role of permafrost in the movement of potentially toxic substances carried in water flow over the surface and through the active layer; det. rates and amnts. of deposition of these materials in the active layer, the upper part of the permafrost zone and in the sediments and water of lakes and ponds in the vicinity of the dump; assess the changes to the nearby environ. duri...
