Mechanical and thermal design of embankments built on permafrost
chercheur principal:
Année(s) de permis: 2020 2019
Résumé: This licence has been issued for the scientific research application No.4629. 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. The development of decision-making tools to select the optimal course and the optimal embankm...


Self-stabilization of thaw slumps
chercheur principal:
Année(s) de permis: 2019
Résumé: The research team are studying the natural stabilization of thaw slumps in the aim to eventually develop adapted management strategies for infrastructure at risk. The specific objectives are to assess the variations of thaw slump stabilization across landscapes, regions, and climates; and to assess the positive and negative feedback effects controlling the natural stabilization of thaw slumps....


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
chercheur principal:
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Résumé: This project continues the on-going monitoring program of permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT. The objectives are: 1) To provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and permafrost active layer thickness) and improve characterization of terrain sensitivity in the Macken...


Permafrost, river, and groundwater inputs of trace elements and nutrients to the Mackenzie River estuary
chercheur principal:
Année(s) de permis: 2016
Résumé: 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. ...


Community based permafrost and active layer monitoring program
chercheur principal:
Année(s) de permis: 2013
Résumé: Uniform permafrost and ground surface temperature measurements are one of the more important databases for long-term climatic study as well as remote sensing ground truthing data. Consistency in sensor depth, casing and drilling methods helps in comparison of the spatial and temporal distribution of the permafrost and seasonal conditions. The proposed partnership with the schools aids continuous m...


Arctic Analogues of Utopia and western Elysium Planitia, Mars
chercheur principal:
Année(s) de permis: 2009 2007 2006 2005 2004
Résumé: This project’s objective is to take multiple, small .25kg samples of the active layer of permafrost in areas where patterned ground and thermokarst are present. The data gained will help the researchers in their efforts to understand possible cold climate processes in the northern hemisphere of Mars. The researchers intend to visit areas in the vicinity of Inuvik and Tuktoyaktuk where polygonal...


Permafrost studies: western Arctic coast
chercheur principal:
Année(s) de permis: 1997 1996 1995 1994 1993 1992 1991 1989
Résumé: This permafrost study has been part of a long-term study first initiated in 1951. The researcher will collect data that will allow a better understanding of the growth of the ice wedges, pingos and permafrost....


Climate change and postglacial paleoenvironmental history of peatlands in the Mackenzie Delta area
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: This research is part of an international project that is aimed at documenting the history of changes in the treeline during the Holocene era. While much is known about the environment and climate of this era, little is known about the development of peatlands during this time. I will collect data on peat layering, pollen and fossils in order to determine how the peatlands developed during this ...


Active layer monitoring network in the Mackenzie Valley
chercheur principal:
Année(s) de permis: 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Résumé: In this on-going study, measurements such as maximum depth of thaw and soil surface movements (from last season) will be taken. Equipment will then be reset for the coming year. Field sites in the Mackenzie Delta between Arctic Red River and Tuktoyaktuk will be visited during June. During July, we will travel between Fort Simpson and San Sault Rapids....


Surface Shear Wave Seismic Profiling and Drilling
chercheur principal:
Année(s) de permis: 1994 1993 1993 1992 1992 1991
Résumé: The Geological Survey of Canada, as part of its on-going research activities, is planning to carry out a geotechnical survey in order to improve certain techniques used in investigating permafrost and ground ice characteristics. The techniques used are shear wave seismic reflection profiling (to determine soil properties) and drilling (to determine the origin of massive ground ice bodies in the v...
