Sediment Transport Processes in Canyon Creek, Sahtu Settlement Region
Principal Investigator: Rempel, Laura L
Licensed Year(s): 2006 2005
Summary: The aim of this study is to characterize sediment transport processes, including bed scour and fine sediment deposition, in a sub-arctic stream intersected by the proposed Mackenzie Gas Pipeline. The specific objectives of the study are: characterization of surface and sub-surface bed sediment texture for all habitat types; measurement of bed scour depth and transport distance of sediment due to ...

Environmental Soil Chemistry at Abandoned Drilling Mud-Sumps in the Kendall Island Bird Sanctuary, Mackenzie Delta Region
Principal Investigator: Biggar, Kevin
Licensed Year(s): 2006 2005
Summary: Since the 1970s, the oil and gas industry has drilled at least nineteen exploratory wells in the Kendall Island Bird Sanctuary. Observations at associated drilling mud-sumps have been made; however, there remains a paucity of field data describing site conditions. It is also appreciated that construction of the proposed Mackenzie Valley pipeline will stimulate the development of Niglintgak and Tag...

Environmental Conditions at Abandoned Drilling Mud-Sumps and Surrounding Terrain in the Outer Mackenzie Delta (Kendall Island Bird Sanctuary)
Principal Investigator: Kokelj, Steven V
Licensed 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...

Biocomplexity of frost-boil ecosystems
Principal Investigator: Walker, Donald A
Licensed Year(s): 2006 2005 2004 2003
Summary: The goal of this project is to understand the complex linkages between biogeochemical cycles, vegetation, disturbance and climate across the full summer temperature gradient in the Arctic in order to better predict ecosystem responses to changing climate...

Hay River Ice Jam Study
Principal Investigator: Hicks, Faye E
Licensed Year(s): 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004
Summary: SUMMARY OF AMENDMENT: This amendment is to include bathymetry work in August 2005 and to start earlier in the fall to monitor fall freezeup. The amendment allows the researchers to address the community's request that the potential effects of man-made features along the river be considered in detail as part of the Hay River Ice Jam Study. The bathymetry work will be done on August 2-6 and 14-28...

Determining Sensitive Areas and Appropriate Management Practices for the North Karst
Principal Investigator: Hayes, Sharon
Licensed Year(s): 2004
Summary: Boundary expansion processes for Nahanni National Park Reserve have identified the North Karst as an area of considerable interest. This area is significant for its elaborate assemblages of landforms, its individual landforms and its inhibition of the l...

Modelling the Flow and Storage Components in the Lower Liard River Valley
Principal Investigator: Quinton, William L.
Licensed Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2001
Summary: This study seeks to better understand the processes affecting the flow and storage of water in the Lower Liard Valley. This information will be used to improve predictions of runoff and water storage levels. The research will involve continued monitori...

Testing Fish Deterrents for Use Under-Ice in the Mackenzie Delta Area
Principal Investigator: Hannay, David
Licensed Year(s): 2003
Summary: This study is designed to assess the reaction of 4 northern freshwater fish species (Lake trout, Northern Pike, Lake whitefish and Inconnu) to underwater sound and light. Sound signals and strobe lights are commonly used to keep fish away from locations...

Ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT.
Principal Investigator: Kershaw, G. Peter
Licensed Year(s): 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The main study objectives are to: 1) determine the status of permafrost landforms in the study area, and 2) determine long-term recovery after abandonment of the CANOL No. 1 project. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond the base camp mountain bikes and foot will be the means of transport. Automated microclimate stations powered by solar ene...

Long-term forest-tundra disturbance research
Principal Investigator: Wein, Ross
Licensed Year(s): 1993 1992 1989 1988 1987
Summary: In previous research in the 1970's, experiments and surveys provided information on the recovery rates of vegetation in response to disturbances from human activities. Several predictions about the long-term recovery of vegetation were made at that time. We are now collecting data to determine if these predictions reflect what is actually occurring. This information provides information about l...
