Enhancement of Permafrost Monitoring Network and Collection of Baseline Terrain Information in Mackenzie Valley Corridor, NWT
chercheur principal: Smith, Sharon S
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Résumé: Forty-four sites will be monitored during the course of the project: four sites in Gwich'in Settlement Area, twenty-two sites in the Sahtu Settlement Area and eighteen sites in the Deh Cho Region. Preferred locations will be chosen near existing highway/winter roads or the existing pipeline, trail and cutlines, for continuous site accessibility and to minimize disturbance to the environment. One o...

Enhancement of Permafrost Monitoring Network and collection of baseline terrain information in Mackenzie Valley Corridor - Deh Cho Region
chercheur principal: Smith, Sharon S
Année(s) de permis: 2006
Résumé: The Geological Survey of Canada maintains a network of active layer and permafrost temperature monitoring sites in the Mackenzie region in order to document the response of permafrost conditions to climate change. Gaps exist in the network in the permafrost zones north of Norman Wells, the Mackenzie Delta region, and on shorelines and coastlines. Enhancement of the network is essential to provide ...

chercheur principal: Forbes, Donald L
Année(s) de permis: 2006 2005 2004 2003 2002 2001
Résumé: The western Canadian Arctic coast is one of the most rapidly changing coastlines in the world and among the most vulnerable to climate change. The causes of this vulnerability have been studied over the past decade. This project involves monitoring coast...

Testing of Surface Geophysical Techniques for the Detection of Ice-bonded Permafrost
chercheur principal: Good, Ron
Année(s) de permis: 2002
Résumé: This research is part of an ongoing program to develop geophysical standards for pipeline route surveying. This line has been chosen because past shallow drilling programs on this line have provided us with a great deal of ground truth, geology, temperat...

Permafrost response to recent climate warming in the Mackenzie Delta and Yukon Coast.
chercheur principal: Wolfe, Stephen A
Année(s) de permis: 1999
Résumé: The objective of the present study is to assess the impact of recent warming, including the warm summer of 1998, on active layer thicknesses and slope stability in the Mackenzie Delta, N.W.T. and Yukon North Slope. The main mode of transportation will be by helicopter (206L) and by boat to transport people. The helicopter will be based out of Inuvik with a fuel cache at Tuktoyaktuk. The helicop...

Soil Climates of the Mackenzie Valley
chercheur principal: Tarnocai, Charles
Année(s) de permis: 1994
Résumé: Soil (at seven depths) and air temperature data are recorded by data loggers. These loggers are programmed to collect data every 3 hours on the hour. The sites are visited twice a year to reprogram the loggers. In addition, active layer depth and subsidence are also recorded during the fall visit. Researchers will collect this data in order to determine the effect of climate change on the envi...

Impact of Climatic Change on Earth Surface Processes, Fosheim Peninsula, Ellesmere Island
chercheur principal: Lewkowicz, Antoni G
Année(s) de permis: 1994 1993 1992 1991 1990 1988 1987
Résumé: The aim of this ongoing research is to establish links between climate and the movements of soil. By collecting this type of data, it may be possible to determine the effect that climate changes may have on the movements of soil down slopes, into rivers and eventually into the sea. The project has been underway for several years because soil movements are mostly slow and therefore difficult to mea...

Ground ice studies of the Tuktoyaktuk coastlands
chercheur principal: Dallimore, Scott R
Année(s) de permis: 1994 1993 1993 1992 1992 1991
Résumé: Measurements of slope and ground temperature will be collected at three sites located east of Tuktoyaktuk and on northern Richards Island. Selection of the sites will be determined in the field but are expected to be at a location south of Gruben's fish camp in Eskimo Lakes and at the west end of Richards Island at North Head....

Licence #2111
chercheur principal: Wankiewicz, Anthony
Année(s) de permis: 1977
Résumé: To study permafrost near Arctic streams at sites near Inuvik and several locations in the Keewatin.
