Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
Principal Investigator: Smith, Sharon S
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: This project continues the on-going monitoring program of permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT. The objectives are: 1) To provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and permafrost active layer thickness) and improve characterization of terrain sensitivity in the Macken...


Influence of changing active-layer thickness on permafrost peatland trace gas exchanges and carbon balance
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The project of the present application is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Scotty Creek, established in 2013 as part of licence #15816. The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an open-path infra-red gas analyzer and a sonic anemometer. These measurements are ...


Measuring Carbon Fluxes at Illisarvik with Eddy Covariance
Principal Investigator: Skeeter, Wesley R
Licenced Year(s): 2016
Summary: The study will measure carbon dioxide (CO2) and methane (CH4) fluxes at Illisarvik during the peak of the growing season using a combination of eddy covariance and gas chamber methods. The primary objective will be to determine the magnitude of CO2 and CH4 fluxes and determine whether sequestration offsets emission. Secondary objectives will be to observe the temporal and spatial variability of th...


Exchange of carbon gas fluxes over low arctic tundra
Principal Investigator: Lafleur, Peter M
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2007 2005 2004
Summary: The research team intends to study how important greenhouse gases, carbon dioxide and methane, are exchanged between tundra surfaces and the atmosphere. They will measure these exchanges over various tundra types and relate them to environmental variables such as soil properties and weather, in hopes of understanding more about how future climate change will impact the land surface and how these ...


Environmental Studies Across Tree Line
Principal Investigator: Kokelj, Steven V
Licenced Year(s): 2012 2011 2010 2009 2008 2007 2006 2005
Summary: This licence is being issued for the scientific research application no. 978. The objectives of this research are to: 1) Monitor permafrost conditions in the Mackenzie Delta region; 2) examine freeze-back of the active layer and associated strength properties of freezing soil; 3) examine the influence of shrub removal on frozen ground and snow conditions at abandoned drilling-mud sumps; 4) inve...


Active Layer Monitoring Network in the Mackenzie Valley
Principal Investigator: Nixon, Frederick M
Licenced Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...


Spatial variability of active-layer thickness and surface characteristics
Principal Investigator: Nguyen, Thai-Nguyen
Licenced Year(s): 2006 2005
Summary: The objective of this research is to determine the spatial correlation between surface properties and active-layer thickness. Six sites have been established across the treeline, between Inuvik and Swimming Point. At each site, shallow temperature cables are installed in the active-layer and near-surface permafrost and air temperatures are monitored by data logger. During this project, the res...


Surficial Geology of Mackenzie Corridor
Principal Investigator: Duk-Rodkin, Alejandra ADR
Licenced Year(s): 2007 2006 2005 2004
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,...

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,...


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...
