Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
Principal Investigator: Kershaw, G. Peter
Licenced Year(s): 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Summary: The objectives of this research are: 1) to determine the status of permafrost landforms. 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 palsas (low peat covered mounds with permafrost cores). The stations keep a record of permafrost and near-surface temperatures. Depth of...


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
Principal Investigator: Smith, Sharon S
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The objectives of this research are: • To provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and permafrost active layer thickness) and improve characterization of terrain sensitivity in the Mackenzie Valley. • Monitor ground temperature and active layer to detect changes in permafrost conditions resulting from surface disturbance or climate change a...


Mackenzie Valley Landslide Geotechnical Investigations
Principal Investigator: Nichol, Susan L.
Licenced Year(s): 2005
Summary: The objective is to improve knowledge about landslides in the Mackenzie Valley. The results of this study will enable better environmental impact assessments and help to reduce environmental impacts related to the construction and operation of the proposed Mackenzie Valley pipeline. As well, the results will have a broader application to a wide range of future development activities in the region....


Permafrost and climate change, western Arctic Canada
Principal Investigator: Burn, Chris R
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The researchers hope to measure ground temperatures to find out how they are changing as a result of climate change. They will try to find out how the thickness of the snow cover affects the amount of ground warming that has occurred over the past 35 years. The researchers will study the cracking of ice wedges to find out if they are cracking less now than they did in the 1970s and 1980s. The...


Licence #1899
Principal Investigator: Bliss, Lawrence
Licenced Year(s): 1975
Summary: To determine plant responses to environmental changes which result from disturbances and how surface disturbance alters soil heat and moisture regimes, for Arctic Land Use Research Program....
