Impacts from climate change on berry productivity in the Canadian Arctic: Integrating community participation with science
Principal Investigator: Desrosiers, Sarah CE
Licenced Year(s): 2013 2012
Summary: The main objective of the Berry Project is to establish a long-term community-based monitoring program in arctic communities using culturally important berry species as indicators of climate change. The project’s main objectives for the Daring Lake Tundra Science Camp are to bring awareness to the effects of climate change and to expand environmental stewardship. These goals can be achieved by del...


Permafrost Investigations and Climate Change, Western Arctic Canada
Principal Investigator: Burn, Chris R
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The principal objective of most of the work is to determine how permafrost conditions in the western Arctic will respond to climate change. This affects how the ground will be able to support development projects in the future. The researchers are collecting data on ground temperatures in the region and finding out how they have changed over the last 35 years. The researchers will travel to I...


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...


Environmental studies across the treeline
Principal Investigator: Kokelj, Steven V
Licenced Year(s): 2012 2011 2010 2009 2008 2007 2006 2005
Summary: The goals of this collaborative research program initiated by the Water Resources Division, DIAND are to: 1) enhance the understanding of environmental conditions in the Mackenzie Delta region; 2) examine the effects of global climate change on the Delta region; and 3) develop a knowledge base that can be directly applied to environmental decision-making in the context of planning, assessment and ...


Variation of near-surface ground temperatures in spruce forests, Mackenzie Delta, Northwest Territories
Principal Investigator: Kanigan, Julian
Licenced Year(s): 2007 2006
Summary: An understanding of near-surface ground temperatures will provide a baseline to assess change and identify sensitive areas. The objective of this project is to determine the variation of near-surface ground temperatures within the Mackenzie Delta. Investigations have identified four spruce forest communities in the delta based on composition: spruce-alder-bearberry, spruce-feathermoss, spruce-crow...


2006-2008 JOGMEC-NRCan Mallik Gas Hydrate Research and Development Project
Principal Investigator: Dallimore, Scott R
Licenced Year(s): 2008 2007 2002 1998
Summary: The objectives of the study are to: characterize gas hydrates at Mallik using state-of-the-art well log data; collect high-quality core samples for measurement of gas hydrate production parameters (e.g. hydraulic permeability, thermal conductivity, pore water geochemistry); conduct ground temperature monitoring to depths of greater than 1 km to evaluate gas hydrate stability; integrate data to bet...


Enhancement of Permafrost Monitoring Network and collection of baseline terrain information in Mackenzie Valley Corridor - Deh Cho Region
Principal Investigator: Smith, Sharon S
Licenced Year(s): 2006
Summary: The Geological Survey of Canada maintains a network of active layer and permafrost temperature monitoring sites in the Mackenzie region in order to document the response of permafrost conditions to climate change. Gaps exist in the network in the permafrost zones north of Norman Wells, the Mackenzie Delta region, and on shorelines and coastlines. Enhancement of the network is essential to provide ...


Enhancement of Permafrost Monitoring Network and Collection of Baseline Terrain Information in the Mackenzie Valley Corridor - K'asho Got'ine District, Sahtu Settlement Area
Principal Investigator: Smith, Sharon S
Licenced Year(s): 2006
Summary: Twelve sampling sites in the K'asho Got’ine District of the Sahtu Settlement Area have been selected for this project, with preferred locations chosen near existing winter roads and the C.N.T. trail for continuous site accessibility and to minimize disturbance to the environment. One or two boreholes up to 20 m in depth will be drilled at each site in order to capture local environmental variabili...


The effect of Great Slave Lake on air and surface temperatures in peatlands near Yellowknife
Principal Investigator: Karunaratne, Kumari C
Licenced Year(s): 2005 2004 2003
Summary: The objective of this project is to determine the effect of Great Slave Lake on air and surface temperatures, and permafrost conditions. Each of the study sites along the Ingram Trail that were instrumented with air and surface temperature sensors during summer 2003 will be revisited in 2005. The data loggers will be downloaded, relaunched and the batteries will be replaced at each instrumentati...


Mackenzie Valley Landslide Geotechnical Investigations
Principal Investigator: Nichol, Susan L.
Licenced Year(s): 2005
Summary: The objective is to improve knowledge about landslides in the Mackenzie Valley. The results of this study will enable better environmental impact assessments and help to reduce environmental impacts related to the construction and operation of the proposed Mackenzie Valley pipeline. As well, the results will have a broader application to a wide range of future development activities in the region....
