Mechanical and thermal design of embankments built on permafrost
Principal Investigator: Bilodeau, Jean-Pascal
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5914. The main objective is to develop a practical method for the mechanical and thermal design of embankments built on permafrost based on the properties of the active layer and of the permafrost, as well as the loading conditions. An existing thin section of the highway embankment built on permafrost has been instrume...


Investigating the susceptibility of drilling mud sumps to permafrost thaw - ThinIce
Principal Investigator: Langer, Moritz
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5833. This research aims to describe permafrost conditions and assess environmental risk at several drilling waste sumps in the Mackenzie Delta region, NWT. The objectives of this project are: 1) Assess the vulnerability of drilling mud sumps in the Mackenzie Delta region under varying site conditions and different clim...


Permafrost and ground hazard mapping along the Inuvik-Tuktoyaktuk Highway using airborne geophysics
Principal Investigator: Froese, Duane G
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5688. The objectives of this research project are to: 1) fly multiple lines of airborne electromagnetic (AEM) geophysical data (between 4 and 6 parallel lines ~100 m apart) between Inuvik and Tuktoyaktuk, beginning and ending just outside the communities; 2) using the geophysical and geological data, produce maps of the In...


Examining the impacts of climate and environmental change on aquatic and terrestrial ecosystems of the Mackenzie region, NWT
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: This research will continue the long term objective of documenting and understanding the impacts of recent climate change on northern terrestrial and aquatic ecosystems. The short term objectives of my research for 2018 are: 1) to investigate the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems; 2) to examine the limnological implications of drained lakes on ...


Assessing Impacts of Permafrost Degradation on Community Infrastructure Due to Climate Change: Modeling, Simulation and Adaptation Costing
Principal Investigator: Zhou, Fuqun
Licensed Year(s): 2004
Summary: Structural infrastructure in northern communities is dependent on the permafrost layer for stability. The thawing and disappearance of the permafrost layer has accelerated in recent decades, damaging buildings and other infrastructure, and causing public...


Permafrost investigations, Mackenzie Delta region, N.W.T.
Principal Investigator: Kokelj, Steven V
Licensed Year(s): 2004 2003 2002 2001 2000 2000 1999
Summary: This study investigates the physical and chemical characteristics of permafrost in the Mackenzie Delta region. The thawing of ice-rich permafrost can result in subsidence or terrain instability. Determination of thaw-sensitive terrain is required to pla...


Reconstruction of Holocene Environments
Principal Investigator: Begin, Christian
Licensed Year(s): 1990
Summary: The research team will investigate a few localities to determine the best sites to study eolian deposits (sand dunes) and features related to permafrost degradation. Samples of granular and organic deposits will be taken....
