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...


Great Bear River Environmental and Traditional Knowledge Baseline Program
chercheur principal: Lennie-Misgeld, Peter
Année(s) de permis: 2011 2010
Résumé: The main objective of the program is to collect fisheries and environmental baseline information to better understand the environmental characteristics of the Great Bear River and to support potential future development of hydropower on the Great Bear River. The program is not being conducted to support a specific project as there are no hydropower projects planned for the Great Bear River at thi...


Mapping and Modeling Carbon Flux in Northern Canada Related to Land Use Change
chercheur principal: Chen, Wenjun
Année(s) de permis: 2005 2004
Résumé: The research team is working to become familiar with the impact of human disturbances on vegetation in northern Canada for their carbon studies. The objective of this study is to collect vegetation and biophysical data for use as verification of ground cover type and disturbance for use in satellite imagery classification and biomass and soil sampling for carbon modeling along the Ingraham Trail....


Digital Database of Vegetation Types of the Mackenzie Valley Development Corridor
chercheur principal: Squires Taylor, Cindy
Année(s) de permis: 1992 1991
Résumé: The researcher and her team will conduct helicopter surveys of vegetation types. The field data will aid in the computer classification of satellite imagery. The results will be vegetation maps of the Mackenzie Valley, which can be plotted on paper or entered into a digital database on a geographic information system (GIS) for further analysis with other data such as wildlife habitat, forest fir...


An Evaluation of SPOT Data to Map Ground Cover in the Canadian High Arctic
chercheur principal: Jetty, Tammy
Année(s) de permis: 1991
Résumé: The Researcher will carry out fieldwork in association with Dr. Cheryl M. Pearce. The study will investigate if the the response of arctic surfaces to climate changes can be detected, monitored and mapped using space imagery....


An Evaluation of Satellite Data to Detect and Monitor Vegetation Responses to Climate Warming at Treeline
chercheur principal: Pearce, Cheryl M.
Année(s) de permis: 1993 1992 1991 1990
Résumé: The Researcher will continue to determine what density of trees is necessary for detection by the satellite sensors. To determine what are the densities of shrubs and herbs or dwarf shrubs and lichens that change the reflectance patterns from the understory. To determine if the thresholds in density will be sensitive enough to monitor vegetation responses to climate change in the forest to tundra ...
