Biocomplexity of frost-boil ecosystems
Principal Investigator: Walker, Donald A
Licenced Year(s): 2006 2005 2004 2003
Summary: The central goal of this project is to understand the complex linkages between biogeochemical cycles, vegetation, disturbance, and climate across the full summer temperature gradient in the Arctic in order to better predict ecosystem responses to changing climate. A group of 4-6 researchers will fly to Green Cabin on Banks Island, on to Mould Bay on Prince Patrick Island, and then to Isachsen o...


Permafrost investigations in 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: Changes in the ground due to uplift, associated with the growth of a pingo, and sideways movements due to the growth of ice wedges, will be measured. Air, ground, and lake water temperatures will be measured, in order to find out how the ground is responding to climatic variation. The reseach team will also return to Paulatuk, to continue studies Dr. Mackay began there 50 years ago. Travel to s...


Investigation of ground ice development in sediments of the Mackenzie Delta area
Principal Investigator: Burn, Chris R
Licenced 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....


Palsa Evolution in Alpine Tundra (PEAT)
Principal Investigator: Kershaw, G. Peter
Licenced Year(s): 1992
Summary: The researcher and his team will determine the current status and contemporary characteristics of palsas (frozen peat mounds), and their environments within this mountainous study area. As well, they will quanititatively describe the processes affecting the evolution of these periglacial features and the potential changes in the status of these and related forms under global change models....


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....


Licence #5037
Principal Investigator: Dyke, Larry
Licenced Year(s): 1985
Summary: To re-occupy sites established on Melville Island for the measurement of frost heaving of bedrock. These sites consist of arrays of survey markers which are periodically resurveyed using a theodolite and stadia rod....
