Quantifying permafrost thaw
Principal Investigator: Gruber, Stephan
Licenced Year(s): 2017 2016 2015
Summary: The Objectives of this research are to: 1) understand better how permafrost differs in temperature and chemical/physical characteristics from place to place; 2) understand how these different types of permafrost respond to change (climate/disturbance); and, 3) understand which future changes in permafrost are likely and which are less likely based on computer simulations. The researcher will t...


The frontline of permafrost thaw: a transect of eddy covariance towers across the southern Taiga Plains to better understand changing regional carbon and water budgets
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2017 2016 2015
Summary: Through this project the research team will address the following objectives: 1) determine the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system; 2) determine how these two types of feedback differ between the sporadic and discontinuous permafrost zones; 3) determine if s the reported decrease (increase) in net carbon dioxide (methane) exchange...


North Slave Permafrost Study: Characterizing and Predicting Discontinuous Permafrost for Climate Change Adaptation
Principal Investigator: Wolfe, Stephen A
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010
Summary: This activity describes and predicts the occurrence of discontinuous permafrost in the northern Great Slave Lake region to assist in planning, development and maintenance of community and industry infrastructure. Changes in climate are affecting permafrost distribution, temperatures and geotechnical conditions. Different landscapes across the region are exhibiting varying responses to warming. Thi...


Impacts of forest fire on discontinuous permafrost in the south-western Northwest Territories
Principal Investigator: Lewkowicz, Antoni G
Licenced Year(s): 2017 2016
Summary: The goal of this project is to look at how permafrost is changing following forest fire over a range of environmental conditions, with the purpose of improving how change is modeled in the future. The fires of 2014 in the southwestern Northwest Territories (NWT) provide an opportunity to examine how discontinuous permafrost responds to disturbances. This work is being carried out in collaboration ...


Permafrost Thaw and Implications for the Cycling of Radionuclides in the Canadian North
Principal Investigator: Bond, Matthew J
Licenced Year(s): 2016
Summary: The objective of this research is to determine whether permafrost thaw in the Canadian north is resulting in the release of historic radionuclides to surface waters. The results of this study will be incorporated into a larger model of radionuclide fate and transport in the Canadian north. Field work will involve sampling surface water (triplicate 500 mL samples), groundwater seepage (triplicat...


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...


PermaSAR: Development of a method to detect subsidence by means of DInSAR in permafrost regions
Principal Investigator: Höfle, Bernhard
Licenced Year(s): 2016 2015
Summary: The goal of the proposed study is to develop a new method that improves the detection of vertical movements caused by thawing and freezing processes of the permafrost. Previous studies showed the theoretical use of remote sensing data for such surface deformations, but also highlighted limitations. As these thawing and freezing processes are mainly responsible for such things as streets breaking a...


Climate driven permafrost degradation and its impact on slope failures
Principal Investigator: Beddoe, Ryley
Licenced Year(s): 2016 2015
Summary: The objective of this research is to better understand the impact of climate driven permafrost degradation on slope instabilities and landslides in the region. This research will involve detailed investigation of both landslides that have occurred and slopes that are assessed for being at a high risk of failure. Soil samples will be taken by digging test pits within the active layer with hand ...


Permafrost, river, and groundwater inputs of trace elements and nutrients to the Mackenzie River estuary
Principal Investigator: Charette, Matthew
Licenced Year(s): 2016
Summary: The objectives are to measure a suite of trace elements and isotopes (TEIs) in the active layer and permanently frozen layer of permafrost cores sampled near the Mackenzie River, and to compare these concentrations to those observed in submarine groundwater discharge and Mackenzie River discharge in order to determine whether permafrost-associated TEIs are being transported to the coastal Arctic. ...


Permafrost in the western Arctic
Principal Investigator: Kokelj, Steve V
Licenced Year(s): 2016
Summary: The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and 3) assess the physical and chemical characteristics of permafrost. To achieve the objectives the follow...
