Influence of Mackenzie Delta Channel Thermal Regime on Permafrost
Principal Investigator: Ensom, Timothy P
Licenced Year(s): 2010 2009
Summary: The purpose of this research is to measure the seasonal temperatures of streambeds at several sites in the Mackenzie delta and adjacent tundra uplands, and predict the implications of these temperature patterns for local permafrost conditions. This project will seek to determine whether channel size and depth affect the annual thermal regime of the streambed, and will also use collected temperatu...


Norman Wells Straw Bales and Reflective Surface Test
Principal Investigator: Graburn, Larry
Licenced Year(s): 2006 2005
Summary: The objective of this project is to test the thermal properties of straw bales and reflective surfaces for use on permafrost slopes along a potential pipeline route in the Mackenzie Valley. These materials might be used in conjunction with or as alternatives to wood chips to protect the exposed slopes from surface erosion and reduce the rate of thawing. In mid-February 2006 a bulldozer and brush c...


Modelling the Evaporation and Heat Balance of Great Bear Lake
Principal Investigator: Rouse, Wayne R
Licenced Year(s): 2006 2005 2004
Summary: This is the second year of a study that measures the water balance and thermal regimes of Great Bear Lake so that the researchers can determine the linkages between the lake's behaviour and the atmosphere above. Lake temperatures will be measured with se...


Snow Accumulation/Runoff in High Latitude Permafrost Basins
Principal Investigator: Marsh, Philip
Licenced Year(s): 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Summary: The primary objective of this project is to develop improved understanding of the fluxes of water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek site will be accessed by helicopter and s...


The Influence of Snowcover on the Ground Surface Temperature in Permafrost
Principal Investigator: Riseborough, Dan
Licenced Year(s): 2001 2000
Summary: This study will attempt to understand and predict how cold the ground surface gets in the winter under snow. Transportation to the site will be by helicopter and accommodation at the site will be in tents or at an existing cabin. Travel from camps to sample sites will be by foot. Electronic data recorders were installed in August 2000 to record air, ground and surface temperature through the wi...


Influence of petroleum contamination on soil thermal properties
Principal Investigator: Winnicky, Kim
Licenced Year(s): 1993
Summary: In this study, oil spill sites will be identified and information will be collected on the vegetation, soil and amount of surface oil present. Five soil cores from the sample sites will be collected and analyzed for oil concentrations as well as used for experimentation in order to assess soil thermal properties. The researcher will drive to the study site (Mile 222 on the Canol Road) from Ross ...


Hydrology of snow-filled arctic stream valleys
Principal Investigator: Heron, Richard
Licenced Year(s): 1993 1990
Summary: As part of an ongoing study in which field work was conducted in 1989 and 1990, this year's work will involve a study of the effects that snowdrifts can have on blocking the movement of meltwater in the McMaster River during the spring. Snowdrifts located at several sites along the river will be monitored to determine how they can alter the river's course, how these drifts are eventually broken d...


Licence #2750
Principal Investigator: Woo, Ming-ko
Licenced Year(s): 1982
Summary: 1) To conduct hydrologic and thermal process studies on a small drainage basin. Measurements will be taken of snow melt rates, ice and snow-depths and rates of run-off. 2) To conduct permafrost and hydrologic studies related to management of uranium tailings (this will be a modelling study)....


Licence #2122
Principal Investigator: Muller, Fritz
Licenced Year(s): 1977
Summary: Continuation of long term glaciology and climatology survey program, continuation of assessing environmental effects of North Water polynias....
