Permafrost and climate change, western Arctic Canada
chercheur principal: Burn, Chris R
Année(s) de permis: 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Résumé: The objective of this research is to understand how climate change is affecting permafrost in the western Arctic, particularly in the outer Mackenzie delta. The research team intends to investigate the ice content of the ground and how this may affect terrain stability. The researchers wish to study changes in ground temperature at various locations in the western Arctic, ranging from Herschel Is...


Wind-abraided rocks near Paulatuk, NT
chercheur principal: Burn, Chris R
Année(s) de permis: 2002
Résumé: 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...


Investigation of ground ice development in sediments of the Mackenzie Delta area
chercheur principal: Burn, Chris R
Année(s) de permis: 1997 1996 1995 1994 1993 1992 1991
Résumé: 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....


Spatial variation in the isotopic composition of snowpack in the Mackenzie Delta area
chercheur principal: Burn, Chris R
Année(s) de permis: 1993 1992
Résumé: This on-going research involves the assessment of isotopes in snowpack each winter. Collection of snow and ice at various sites along winter roads in the N.W.T. provides information about the composition of isotopes within a region. Isotopic composition of snow and ice taken from ice cores in Greenland and Antarctica have been able to provide information about past climates....


Investigation of Frost Heave in Lake Bottom Sediments
chercheur principal: Burn, Chris R
Année(s) de permis: 1990 1987
Résumé: 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....
