Investigating the Effects of Winter Overland Travel in sub-Arctic Boreal Forest
Principal Investigator: Kanigan, Julian
Licenced Year(s): 2012 2011
Summary: In discontinuous permafrost of the southern NWT, cleared transportation corridors, such as seismic lines, have recently been associated with permafrost loss, increased soil moisture and vegetation changes. Permafrost loss can lead to ground subsidence, infrastructure instability and the release of stored carbon into the atmosphere. The research team will test whether seismic lines can be construc...


Relations between ground ice and geomorphic setting, Kendall Island Bird Sanctuary, Mackenzie Delta, NWT
Principal Investigator: Morse, Peter D
Licenced Year(s): 2008 2007 2006
Summary: This licence was issued for the scientific research licence application number 748. The project objective is to determine how near-surface wedge ice volumes are related to geomorphic setting, which reflects soil physical properties, moisture contents, and process and duration of ice formation. Wedge ice geometry will be measured with a hand-held CRREL drill, permafrost cores extracted, and s...


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 ...


Surficial geology of Mackenzie Corridor
Principal Investigator: Duk-Rodkin, Alejandra ADR
Licenced Year(s): 2007 2006 2005 2004
Summary: Project objectives are to map, identify, describe characteristics (geotechnical aspects) and date surficial deposits in the vicinity of the proposed pipeline corridor. This knowledge will assess: 1. granular resources. 2. slope instability, landslide occurrence and potential due mainly to instability of the active layer, forest fires and erosion. 3. geochemical analysis on a regional basis of till...


Surficial Geology Mapping Fort Norman (96C), Blackwater Lake (96B), Mahoney Lake (96F)
Principal Investigator: Duk-Rodkin, Alejandra ADR
Licenced Year(s): 2003
Summary: This project aims to obtain a better understanding of the sensitivity of slopes to disturbance from development, especially in the context of progressive climate warming. It will also identify baseline levels for natural and anthropogenic contaminants,...


2002 Route and Site Selection in the Deh Cho Area
Principal Investigator: Povey, Andrew
Licenced Year(s): 2004 2003 2002
Summary: Route and site selection flights will be used to: (1) determine the location for a potential natural gas pipeline route and associated developments through the Deh Cho Region; (2) visually inspect and confirm land forms and geotechnical features; (3) identify land features that may be important to the location or construction of a potential gas pipeline; and (4) determine the locations for poten...


2002 Route and Site Selection in the Inuvialuit Settlement Area
Principal Investigator: Povey, Andrew
Licenced Year(s): 2005 2004 2003 2002
Summary: Route and site selection flights will be used to: (1) determine the location for a potential natural gas pipeline route and associated developments through the Inuvialuit Settlement Area; (2) visually inspect and confirm land forms and geotechnical features; (3) identify land features that may be important to the location or construction of a potential gas pipeline; and (4) determine the locatio...


2002 Route and Site Selection in the Gwich'in Settlement Area
Principal Investigator: Povey, Andrew
Licenced Year(s): 2005 2004 2003 2002
Summary: Route and site selection flights will be used to: (1) determine the location for a potential natural gas pipeline route and associated developments through the Gwich'in Settlement Area; (2) visually inspect and confirm land forms and geotechnical features; (3) identify land features that may be important to the location or construction of a potential gas pipeline; and (4) determine the locations...


2002 Route and Site Selection in the Sahtu Settlement Area
Principal Investigator: Povey, Andrew
Licenced Year(s): 2005 2004 2003 2002
Summary: Route and site selection flights will be used to: (1) determine the location for a potential natural gas pipeline route and associated developments through the Sahtu Settlement Area; (2) visually inspect and confirm land forms and geotechnical features; (3) identify land features that may be important to the location or construction of a potential gas pipeline; and (4) determine the locations fo...


Permafrost investigations in western arctic Canada
Principal Investigator: Burn, Chris R
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: Changes in the ground due to uplift, associated with the growth of a pingo, and sideways movements due to the growth of ice wedges, will be measured. Air, ground, and lake water temperatures will be measured, in order to find out how the ground is responding to climatic variation. The reseach team will also return to Paulatuk, to continue studies Dr. Mackay began there 50 years ago. Travel to s...
