Principal Investigator: Craven, Jim
Licensed Year(s): 2009
Summary: This licence is being issued for the scientific research application no. 956. The primary objective of this study is to field test and assess the utility of an electromagnetic (EM) geophysical technique called magnetotellurics (MT), as an inexpensive method for mapping spatial variations and changes within permafrost in the Mackenzie Delta area. Due to the large change in soil electrical resist...

Licensed Year(s): 2009
Summary: This licence was issued for the scientific research application No. 935. This study will test whether the shallow geophysics techniques of Ground Penetrating Radar and Ohm Mapper Resistivity Logging, in combination with seismic shothole drillers’ logs, can be used to resolve the nature and extent of the surficial geology cover and permafrost characteristics in two areas of recent seismic explor...

Summary: 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...

Summary: Gaps exist in the Mackenzie monitoring network in the permafrost zones north of Norman Wells, the Mackenzie Delta region and shorelines and coastlines. Enhancement of the network is essential to provide baseline information for developments such as pipelines, highways and power lines, and to assess the impact of such development and/or climate change on the environment. In this project, temperatur...

Summary: The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...

Principal Investigator: Nguyen, Thai-Nguyen
Licensed Year(s): 2006 2005
Summary: The climate and numerous field reports indicate that permafrost should be continuous in the Mackenzie Delta. However, the most recent permafrost map in the Atlas of Canada classifies the delta as having discontinuous permafrost. Yet, no extensive fieldwork covering the entire delta has ever been realized. Unfrozen conditions beneath the ground, near shifting channels, have been recognized by vario...

Principal Investigator: Povey, Andrew
Licensed Year(s): 2005 2004 2003 2002
Summary: The 2005 terrestrial studies include vegetation mapping, rare plant surveys, rare plant mitigation planning, timber cruising, and landform, soil and permafrost investigations. All of the studies will be conducted by three- or four-person crews supported by helicopter. A local assistant will be included as part of each terrestrial survey team to assist in observing and recording data taken at surve...

Principal Investigator: Marsh, Philip

Summary: The primary objective of this project is to improve understanding of the changes in water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek, Hans Creek, and Zed Creek sites will be accessed...

Principal Investigator: Kokelj, Steven V
Licensed Year(s): 2004 2003 2002 2001 2000 2000 1999
Summary: This research will investigate: A) the physical and chemical characteristics of permafrost in the Mackenzie Delta region to identify areas of ice-rich permafrost or thaw sensitive terrain. Second; B) the effect of permafrost degradation on water quality...

Principal Investigator: Tait, Matthew P.
Licensed Year(s): 2003
Summary: Oil and gas extraction in permafrost areas causes vertical surface displacements that have in the past caused serious environmental issues, such as massive subsidence and land slides. Methods of monitoring such vertical subsidence are accurate, but rely...
