Evaluating the environmental impacts of permafrost mega-disturbances along the Dempster Highway, NWT
Principal Investigator: Kokelj, Steven V
Licenced Year(s): 2014 2013 2012 2011 2010
Summary: The objective of this research project is to document the extent of ecological change in impacted stream basins draining the eastern slope of the Richardson Mountains and to determine the mechanisms of slump initiation and stabilization. This study will focus on the Stoney Creek catchment, which runs parallel to the Dempster Highway and empties into the Peel River at Fort McPherson, NT. The catchm...


Environmental Studies Across Treeline
Principal Investigator: Kokelj, Steven V
Licenced Year(s): 2012 2011 2010 2009 2008 2007 2006 2005
Summary: This study will include: 1) monitoring permafrost conditions in the Mackenzie Delta region; 2) examining freeze-back of the active layer and associated strength properties of freezing soil; 3) examining the influence of shrub removal on frozen ground and snow conditions at abandoned drilling-mud sumps; 4) investigating effectiveness of different soil sampling protocols on delineating contaminants ...


Environmental Conditions at Abandoned Drilling Mud-Sumps and Surrounding Terrain in the Outer Mackenzie Delta (Kendall Island Bird Sanctuary)
Principal Investigator: Kokelj, Steven V
Licenced Year(s): 2006 2005
Summary: The research team will collect data to assess environmental conditions at well sites and sumps abandoned during the 1970s and 1980s, and in nearby undisturbed terrain in the Kendall Island Bird Sanctuary (KIBS). Study site locations include: Taglu D-43, Taglu H-54, Taglu C-42, Niglintgak B-19, Kumak K-16, Kumak E-58 and Kumak J-06. Permafrost investigations will take place in the surrounding terr...


Ground-thermal Conditions at Abandoned Drilling Mud Sumps, Mackenzie Delta Region, N.W.T.
Principal Investigator: Kokelj, Steven V
Licenced Year(s): 2003
Summary: In the Mackenzie Delta region, many of the drilling mud sumps constructed in the 1970s have partially or completely collapsed. The collapse of a sump can release contaminants previously immobilized in permafrost. The long-term degradation of many sumps...


The growth of aggradational ice in sediments of the Mackenzie Delta, N.W.T.
Principal Investigator: Kokelj, Steven V
Licenced Year(s): 2004 2003 2002 2001 2000 2000 1999
Summary: This project investigates the the distribution and amount of near-surface ice in sediments of the Mackenzie delta area near Inuvik. Sites near Inuvik will be accessed via road and sampled using a hand held power auger. Sites on the Delta will be accessed by boat from a base at Gill's cabin, and sampled with a power auger. In both general areas soil cores will be removed and taken to the Inuvik Res...
