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: 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...


Developing Remote Sensing Tools for Mapping Linear Disturbances in the Sahtu Region of the Northwest Territories
Principal Investigator: Cole, Sarah E
Licenced Year(s): 2015
Summary: The objective is to develop a current and complete development footprint for a designated area of the Central Mackenzie Valley, Northwest Territories (NWT), that includes specified disturbance attributes; captures an estimate of current recovery state; and, provides data to predict disturbance recovery trajectories and project footprint change over time. Anthropogenic disturbance features will ...


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...


Airborne SAR and passive microwave measurements over snow covered tundra for CoReH20 retrieval validation and land surface model testing
Principal Investigator: Derksen, Chris
Licenced Year(s): 2013 2012
Summary: The proposed European Space Agency Earth Explorer 7 CoReH20 satellite mission has the primary objective of retrieving snow water equivalent (SWE) over land at a high spatial resolution (200-500 metres) from X- and Ku-band Synthetic Aperture Radar measurements. This would make available high resolution, satellite derived SWE, for monitoring and modeling applications. To-date, airborne measurements ...


Great Bear River Environmental and Traditional Knowledge Baseline Program
Principal Investigator: Lennie-Misgeld, Peter
Licenced Year(s): 2011 2010
Summary: 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...


RADARSAT Observations of River Ice and Flood Patterns in the Mackenzie River Delta
Principal Investigator: van der Sanden, Josephus J
Licenced Year(s): 2017 2012 2010 2009
Summary: The objective of this research is to investigate the potential of Canada’s RADARSAT satellites as a tool for the collection of information on (change in) river ice conditions and, during spring breakup, flood conditions in the Mackenzie River Delta. Canada’s RADARSAT satellites will be tasked to acquire a time series of images over the Mackenzie Delta from October 2008 to July 2009. To facilita...


Mapping and Modeling Carbon Flux in Northern Canada Related to Land Use Change
Principal Investigator: Chen, Wenjun
Licenced Year(s): 2005 2004
Summary: 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
Principal Investigator: Squires Taylor, Cindy
Licenced Year(s): 1992 1991
Summary: 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
Principal Investigator: Jetty, Tammy
Licenced Year(s): 1991
Summary: 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
Principal Investigator: Pearce, Cheryl M.
Licenced Year(s): 1993 1992 1991 1990
Summary: 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 ...
