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 objective of this research is to understand the rate of ground warming in permafrost due to climate change and to measure the changes in ground surface characteristics that are occurring as a result. In particular, the research team are interested in changes in ground temperature, in the depth of the active layer, and in subsidence of the ground. The team are also interested in measuring how q...

2007 Winter Field Geophysical Investigation Program in the Inuvialuit Settlement Region
Principal Investigator: Hawkins, Jim R.
Licenced Year(s): 2007
Summary: The objective of the program is to map areas along the right-of-way where the ground is unfrozen (taliks) and to locate ice wedges and larger, deeper areas of massive ice, in the Inuvialuit Settlement Region. Shallow geophysical surveys will provide information on subsurface conditions. ARGO tracked vehicles will tow geophysical instruments (EM31, Ohm Mapper, or GEM-2) behind them. A ground-penetr...

Permafrost Studies: Western Arctic Coast
Principal Investigator: Mackay, Ross J.
Licenced Year(s): 1997 1996 1995 1994 1993 1992 1991 1989
Summary: Transportation to and from the field sites will be by helicopter, either from Tuktoyaktuk or Inuvik, to and from Garry Island and Illisarvik (West Point, Richards Island). Most of the equipment used in the field is for measurement purposes , such as surveying equipment for precise height, distance, and tilt determinations of bench marks already installed across ice wedges and elsewhere, temperatu...

Investigations 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 purpose is to collect samples of ground ice and to measure air, ground and lake temperatures. We use the information to help understand how the permafrost in the area has changed in the last few thousand years, in order to determine what might happen in the future....

Licence #7003
Principal Investigator: Mackay, J.R.
Licenced Year(s): 1988 1987
Summary: To understand better the origin of permafrost, the ice within permafrost, and the processes that help create the present geocryologic environment....
