Using Traditional Knowledge of JMRFN Elders to better understand changes in the boreal caribou habitat.
chercheur principal: Laurent, Cyrielle C
Année(s) de permis: 2017
Résumé: 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...

Food Security and Drinking Water Vulnerability Assessment Related to Permafrost Degradation in the Jean Marie River First Nation
chercheur principal: Ireland, Margaret
Année(s) de permis: 2013
Résumé: 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...

A Multi-scale Assessment of Cumulative Impacts in the Northern Mackenzie Basin
chercheur principal: Lantz, Trevor C.
Année(s) de permis: 2016 2015 2014 2013 2012
Résumé: 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...

Lake 5A Mesocosm Study - 3rd Amendment to Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
chercheur principal: Wrona, Frederick J
Année(s) de permis: 2010
Résumé: 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
chercheur principal: Kershaw, G. Peter
Année(s) de permis: 2018 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Résumé: 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 ...

Deltaic Lake Sediments as Recorders of Past Carbon Export from Arctic River Drainage Basins
chercheur principal: Eglinton, Timothy I
Année(s) de permis: 2011 2009 2007
Résumé: This licence is being issued for the scientific research application no. 955. The objective of this research is to collect sediment cores from the Mackenzie River Delta in order to study how the river has behaved in the past, and see if the researchers can detect recent changes due to thawing permafrost. More specifically, the goal is to determine whether the researchers can reconstruct past c...
