Permafrost and climate change, western Arctic Canada
Principal Investigator: Burn, Chris R
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The principal objective of this research is to determine how permafrost conditions in the western Arctic will respond to climate change. Additional objectives are to determine how lake temperatures respond to climate change, and how snow depths affect ground temperatures. How permafrost responds to climate change will affect how the ground supports development projects in the future. Data is be...


Wind-abraided rocks near Paulatuk, NT
Principal Investigator: Burn, Chris R
Licenced Year(s): 2002
Summary: The wind abraided rocks 3 km south of Paulatuk are among the best examples of ventifacts in North America. The rocks have smooth, lichen-free surfaces on their south side, which are blasted by sand and snow during strong southerly winds in winter. The re...


Spatial Variation in the Isotopic Composition of the Snowpack, Mackenzie Delta Area
Principal Investigator: Burn, Chris R
Licenced Year(s): 1993 1992
Summary: The isotopic compostion of snow and ice is used to reconstruct past climates from records of ice-cores collected in Greenland and Antarctica. The ice cores are a few inches in diameter. Sampling in the Delta may reveal how regionally representative samples of snow are. This will enable the results of ice cores to be evaluated in a regional context....


Investigation of Ground Ice Development in Sediments of the Mackenzie Delta
Principal Investigator: Burn, Chris R
Licenced Year(s): 1997 1996 1995 1994 1993 1992 1991
Summary: The Research will continue to examine the hydrology of frost heave in the ideal environment of a lake-bottom. In addition some experimental trials of frost heave in equipment of various sizes will be conducted in winter time. Summer activities are planned in the outer Delta to examine the distribution of ice in the upper layers of permafrost and to investigate permafrost conditions beneath shallow...


Investigation of Frost Heave in Lake Bottom Sediments
Principal Investigator: Burn, Chris R
Licenced Year(s): 1990 1987
Summary: The research team will monitor the amount of heave that occurs in lake-bottom sediments during winter, after water freezes to the bottom of lakes, because these environments are the best for examining the hydrology of frost heaving....
