MOSES Rapid Permafrost Thaw
Principal Investigator: Boike, Julia
Licensed Year(s): 2019 2018
Summary: The goals for this expedition are to test new equipment for characterizing the energy fluxes from and around thermokarst slumps and to establish a baseline for future subsidence measurements. Additionally, lake and atmospheric methane concentrations in relation to thermokarst slumps will be quantified. The research team will conduct ground-truth surveys using a differential GPS. Small GPS obser...


Enhanced Contaminant Transport from Thawing Permafrost in Freshwater Ecosystems
Principal Investigator: Blais, Jules M
Licensed Year(s): 2010
Summary: This research goal is to examine the role of thermokarst development on natural organic matter and the release of metals (e.g. mercury) and organic contaminants (e.g. polychlorinated biphenyls - PCBs). Sampling for contaminants: Water sampling for persistent organic pollutants (POPs) will be done by passive samplers, consisting of a semi-permeable membrane containing a resin that will extract ...


Environmental Studies Across Tree Line
Principal Investigator: Kokelj, Steven V
Licensed Year(s): 2012 2011 2010 2009 2008 2007 2006 2005
Summary: This licence is being issued for the scientific research application no. 978. The objectives of this research are to: 1) Monitor permafrost conditions in the Mackenzie Delta region; 2) examine freeze-back of the active layer and associated strength properties of freezing soil; 3) examine the influence of shrub removal on frozen ground and snow conditions at abandoned drilling-mud sumps; 4) inve...


Possible arctic analogues of Utopia Planitia, Mars
Principal Investigator: Soare, Richard J
Licensed Year(s): 2009 2007 2006 2005 2004
Summary: The objective of this research is to take multiple samples of the active layer of permafrost in areas where patterned ground and thermokarst are present. The data gained will assist in understanding possible cold climate processes in the northern hemisphere of Mars. In recent years, cold-climate landscapes on Earth have come to play an important role in understanding landscapes on Mars. This wo...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licensed Year(s): 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The long-term goal of this project is to develop a biogeochemical model for lakes in the Mackenzie Delta, and ultimately, a more general ecosystem model for floodplains and deltas of major world rivers that will help assess the effects of multiple stresses on rivers resulting from global change. Numerous major river deltas in the Arctic circumpolar region are lake-rich because of thermokarst effec...


Massive Ice Study in Granular Deposits
Principal Investigator: Pollard, Wayne H
Licensed Year(s): 2006 2005 2004 2003
Summary: Sand, gravel and crushed stone are valuable geological resources, collectively known as aggregates. They are essential bed, foundation and building materials. The presence of massive ice in aggregate deposits results in a series of resource management problems, particularly for the oil industry and its contractors who rely on local granular deposits as building material. From an environmental pers...


Vegetation Mapping at Tuktuk Nogait National Park
Principal Investigator: Raillard, Martin
Licensed Year(s): 1998
Summary: This project will take place in Tuktuk Nogait National Park in 1998 and 1999. The objective of the project is to map the vegetation of the park. As many areas of the Park as possible will be hiked and the various vegetation communities along the hiking route will be put into one of several classes, and their exact geographical location recorded. Once the field season is over, these various geograp...


Ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT.
Principal Investigator: Kershaw, G. Peter
Licensed Year(s): 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The main study objectives are to: 1) determine the status of permafrost landforms in the study area, and 2) determine long-term recovery after abandonment of the CANOL No. 1 project. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond the base camp mountain bikes and foot will be the means of transport. Automated microclimate stations powered by solar ene...


Permafrost Investigations, western arctic Canada
Principal Investigator: Burn, C. R.
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The researchers will be collecting samples of ground ice and permafrost soil, and measuring air, ground and lake water temperatures. This information will be used to provide an understanding of how permafrost conditions in the region have changed in the last few thousand years. Also measuring ground movement to determine how the ground deforms during the year, in particular, we will be measuring ...


Investigation of ground ice development in sediments of the Mackenzie delta area.
Principal Investigator: Burn, Chris R
Licensed 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 thousands years, in order to determine what might happen in the future....
