North Slave Permafrost Study: Characterizing and Predicting Discontinuous Permafrost for Climate Change Adaptation
Principal Investigator: Wolfe, Stephen A
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010
Summary: This activity describes and predicts the occurrence of discontinuous permafrost in the northern Great Slave Lake region to assist in planning, development and maintenance of community and industry infrastructure. Changes in climate are affecting permafrost distribution, temperatures and geotechnical conditions. Different landscapes across the region are exhibiting varying responses to warming. Thi...


How will fish communities in Gwich’in and Inuvialuit lakes respond to climate change?
Principal Investigator: Gray, Derek K
Licenced Year(s): 2018 2017
Summary: Purpose of this project is to obtain baseline data for fish communities in Gwich’in Settlement Area (GSA) and Inuvialuit Settlement Region (ISR) lakes and use these data to predict future changes in fish communities caused by climate change. Specific objectives are: 1) to develop a baseline data set for fish populations, fish habitat, water quality, and water temperature for small and mediu...


Quantifying permafrost thaw
Principal Investigator: Gruber, Stephan
Licenced Year(s): 2018 2017 2016 2015
Summary: The objectives of this research are: 1) to understand better how permafrost differs in temperature and chemical/physical characteristics from place to place; 2) to understand how these different types of permafrost respond to change (climate/disturbance); and, 3) to understanding which future changes in permafrost are likely and which are less likely based on computer simulations. The research ...


Beaulieu River Belt Collaborative VMS Project
Principal Investigator: Knox, Bernadette
Licenced Year(s): 2018 2017 2016
Summary: The objectives of this project are to update and increase the understanding of the geological history of an area along the Beaulieu River. The work will be conducted mostly on foot with access to the shore provided by canoe and zodiac boat. Notes on the geology will be taken and entered into a database. Holes up to 1m in depth will be dug to make observations and take samples of the till, the h...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
Principal Investigator: Mamet, Steve D
Licenced Year(s): 2018 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Summary: The objectives of this project are to determine: 1) the status of permafrost landforms; 2) long-term recovery after abandonment of the CANOL No. 1 project, including oil spills and gravel pits; and, 3) Status of treeline. Since 1990, automated microclimate stations powered by solar cells have been operated in the study area. One station is located at each of five permafrost landforms called pal...


Productivity and mercury trends in Great Bear Lake
Principal Investigator: Evans, Marlene S.
Licenced Year(s): 2018
Summary: The objectives of this research project are to collect sediment cores from up to six sites in Great Bear Lake to investigate the temporal record of diatom and lake productivity and the deposition of mercury and other metals; to investigate spatial gradients in lake productivity as influenced by station depth, distance from shore, and river influences; and to continue to investigate mercury levels ...


Using Novel Technology to Survey Methane Emissions in the Mackenzie Delta
Principal Investigator: Layden, Ronald E.
Licenced Year(s): 2018
Summary: The research team plan to map the amount and source of methane in some or all of the following: 1. Thaw slump sites along the Mackenzie River between Tsiigehtchic and the outer Delta. 2. Upland sites between Inuvik and Tuktoyaktuk including the following types of areas: a. Former gas production sites; b. Drilling and discovery work sites and pads; and, c. Thaw slumps at pit sites along the ...


Forest Ecotone Experiment
Principal Investigator: Eitel, Jan
Licenced Year(s): 2018 2017
Summary: The overarching objective of the study is to integrate light detection and ranging (LiDAR), passive spectral, and tree ecophysiological data to link biophysical structure to ecological function in the Forest Tundra Ecotone. In so doing, the research team will be able to remotely assess the vulnerability and resilience of the forest tundra ecotone (FTE) to environmental change. The field work wi...


Investigating the relationship between snow microstructure and airborne synthetic aperature radar measurements of tundra snow to improve environmental prediction capabilities in polar regions
Principal Investigator: Derksen, Chris
Licenced Year(s): 2018
Summary: New high resolution Ku- and Ka-band synthetic aperture radar (SAR) measurements are being proposed to measure tundra snow water equivalent (SWE) from future space-borne sensors, however further work is necessary to test the mission concept using airborne instruments that replicate the proposed satellite sensors. During the winter of 2012-2013 a research campaign at the Trail Valley Creek study sit...


Taltson Hydroelectric Facility Aquatic Monitoring
Principal Investigator: Miller, Matthew
Licenced Year(s): 2018 2017 2016
Summary: The objective of the monitoring and mitigation is to determine operating procedures and mitigation options for the annual shutdown at Taltson Hydroelectric Facility to minimize the environmental impact on downstream Trudel Creek. Various mitigation options have been and are being assessed and the results on Trudel Creek are being monitoring to determine the best operating procedure for the ann...
