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: 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 the research team will obtain Landsat satellite images that will provide reflectance measurements covering a 1...


Effects of permafrost disturbances on terrestrial and aquatic ecosystems, Banks Island, NWT, Canada
chercheur principal: Lacelle, Denis
Année(s) de permis: 2015
Résumé: Thaw slumps are one of the most dramatic thermokarst features in permafrost regions. The number of thaw slumps on Banks Island has more than tripled in recent decades and it is likely that this change is altering terrestrial and aquatic ecosystems. This multidisciplinary research project investigates the short- (1960s-present day) and long-term (Medieval Warm Period to today) impacts of permafrost...


The cumulative impacts of rapid environmental change in the northwestern NWT: Investigating the impacts of mega-slump disturbances on terrestrial and aquatic ecosystems in the lower Peel watershed, NW
chercheur principal: Lacelle, Denis
Année(s) de permis: 2013 2012
Résumé: This is a multidisciplinary project involving communities, governments and academic researchers. The goals are to: 1) inventory and track broad scale changes in landscape disturbances; 2) determine the impacts of natural and anthropogenic disturbances on the physical and chemical characteristics and ecology of streams and rivers; 3) determine disturbance thresholds relevant to the health of stream...
