Using Traditional Knowledge of JMRFN Elders to better understand changes in the boreal caribou habitat.
Principal Investigator: Laurent, Cyrielle C
Licenced Year(s): 2017
Summary: This project aims to demonstrate the cumulative impact of permafrost degradation and forest fire on boreal caribou habitat and how caribou habitat degradation affects Jean Marie River First Nation (JMRFN). To do this the research team will collect and use traditional knowledge (TK), and analyse it in a geographic information system (GIS) with scientific data. The research team expect to locate are...


Examining the impacts of climate and environmental change on aquatic and terrestrial ecosystems of the Mackenzie region, NWT
Principal Investigator: Pisaric, Michael FJ
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: This research will continue the long term objective of documenting and understanding the impacts of recent climate change on northern terrestrial and aquatic ecosystems. The short term objectives of this research are: 1) to investigate the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems; 2) to examine the limnological implications of drained lakes on aquatic...


Food Security and Drinking Water Vulnerability Assessment Related to Permafrost Degradation in the Jean Marie River First Nation
Principal Investigator: Ireland, Margaret
Licenced Year(s): 2013
Summary: The main objective of this one year project is to provide the community with a practical tool for assessing Jean Marie River’s (JMR’s) vulnerability to food security in relation to country foods, as well as the vulnerability of sources of country foods and drinkable water used by the community members out on the land, in the context of climate change. This tool will consist of a mapping of permafr...


Permafrost vulnerability assessment and landscape changes related to climate change in the Jean Marie River First Nation
Principal Investigator: Ireland, Margaret
Licenced Year(s): 2012
Summary: The objectives of this project are to: 1. Gather Traditional, local, and scientific knowledge and information concerning environmental and cultural changes related to climate change and permafrost degradation. 2. Conduct a focus group mapping session, a geological survey, and an air photo survey of Jean Marie River (JMR) and the surrounding area to locate vulnerable areas of land to climate c...


A Multi-scale Assessment of Cumulative Impacts in the Northern Mackenzie Basin
Principal Investigator: Lantz, Trevor C.
Licenced Year(s): 2016 2015 2014 2013 2012
Summary: This project has three main objectives: Objective 1: To use satellite imagery (Landsat, QuickBird, InSAR, etc.) to document the rate and extent of landscape change (slumps, subsidence, vegetation change, etc.) in the northern Mackenzie Basin. To quantify landscape disturbances and vegetation regeneration patterns since 1985 Landsat satellite images will be obtained, that will provide refle...


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...


Enhanced Contaminant Transport from Thawing Permafrost in Freshwater Ecosystems
Principal Investigator: Blais, Jules M
Licenced Year(s): 2010
Summary: This research goal is to examine the role of thermokarst development on natural organic matter and the release of metals (e.g. mercury) and organic contaminants (e.g. polychlorinated biphenyls - PCBs). Sampling for contaminants: Water sampling for persistent organic pollutants (POPs) will be done by passive samplers, consisting of a semi-permeable membrane containing a resin that will extract ...


Lake 5A Mesocosm Study - 3rd Amendment to Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
Principal Investigator: Wrona, Frederick J
Licenced Year(s): 2010
Summary: The overall objective of the Lake 5A mesocosm study is to better understand the impact of permafrost thaw shoreline slumping (an analogue for a warming climate) on the bottom components of the aquatic food-web in small Arctic tundra lakes in order to better predict the effects of a warming climate on food-web structure, function and productivity. To assess the direct and indirect effects of per...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
Principal Investigator: Kershaw, G. Peter
Licenced Year(s): 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Summary: Permafrost landforms are shrinking in response to climate warming. The researchers want to measure the amount of change each year and to measure the temperature of the permafrost year-round. In addition they want to measure the rate of plant recovery on disturbed areas resulting from the CANOL Project (1942-45). Access during the summer is via the Yukon along the Canol Road through Macmillan ...


Thaw flows and ground ice investigation in sediments in Fort McPherson region, NWT
Principal Investigator: LAURIOL, Bernard
Licenced Year(s): 2009
Summary: The main goal of this project is to determine the distribution, nature and origin of three thaw flows and the ground ice bodies in the Fort McPherson region. The results will be useful to understand similar features present along the Richardson Mountains. The researchers plan to spend a full week in the Fort McPherson region to sample the ice and the sediment. The field camp will be based at th...
