Principal Investigator: Vieira, Gonçalo
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5639. The goal of this research project is to better understand the characteristics of various different lakes, how their characteristics vary, as well as their potential relation to permafrost thaw events in the recent or distant past. The frequency of occurrence across space and time as well as the variability of: 1) opt...

Licensed Year(s): 2022 2021 2020 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.5168. The specific objectives of the project are as follows: 1) Determine the spatial extent, distribution, and timing of winter icing events in streams along the Inuvik to Tuktoyaktuk Highway (ITH) through ground-based and aerial reconnaissance of stream crossings; 2) Identify relations between physical watershed charact...

Licensed Year(s): 2021 2021 2020 2019 2018
Summary: This licence has been issued for the scientific research application No.4934. The purpose of this study is to develop a method of characterizing the sensitivity and response of streams and rivers to regional variability in permafrost thaw in the Beaufort Delta Region, Western Canadian Arctic. All of the field team members are from within the NWT. This field program will follow the attached E...

Licensed Year(s): 2020 2019 2018 2017 2016
Summary: This licence has been issued for the scientific research application No.4663. The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and 3) to assess the physical...

Principal Investigator: Charette, Matthew
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: Wookey, Philip A
Licensed Year(s): 2014 2013
Summary: This research aims to understand what factors affect 1) the amount of carbon stored in tundra soils, and 2) the conversion of this soil carbon into greenhouse gases (carbon dioxide and methane). In particular, the research team wants to understand how hydrology (which is the distribution and movement of water in soils and streams) might affect the carbon cycle under future global warming. This inc...

Principal Investigator: Nixon, Frederick M
Licensed Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Summary: The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...

Principal Investigator: Marsh, Philip
Licensed Year(s): 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Summary: The primary objective of this project is to improve understanding of the changes in water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek, Hans Creek, and Zed Creek sites will be accessed...

Principal Investigator: Burn, Chris R
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991
Summary: The researcher will continue to collect samples of ground ice and measure temperatures in lakes and ponds. This information is used to help understand how the ground heaves as it freezes in winter, and to determine the extent of soil settlement during thaw in summer. The information about lakes is used to help understand the relations between water depths and temperatures beneath the lake....

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....
