Summary: The two main objectives are: to map changes in vegetation productivity on an annual basis across the Bathurst caribou herd’s range using satellite imagery obtained from NASA’s MODIS sensor (available since 2000) and analyze these data to identify where the most significant changes have occurred; and to collect and analyze data on the growth, establishment, and mortality of shrubs and trees over th...

Summary: For this project the research team will conduct the collection of microwave radar backscatter data of permafrost and boreal forest at wavelengths of 3cm (X-band), 6cm (C-band), 10cm (S-band) and 23cm (L-band). This process will capture two stable permafrost active layer states: thawed and frozen. The research team will derive information about permafrost (e.g. soil status, soil moisture) and about...

Summary: This project aims to evaluate and develop the utility of Canada’s future RADARSAT Constellation Mission (RCM) (launch 2018) for the monitoring of lake ice breakup and freeze-up. RCM-type radar images will be simulated using data from Canada’s current radar satellite – that is - RADARSAT-2. Validation data in the form of oblique aerial photographs are required to assess the accuracy of the image pr...

Summary: Objectives of this research project are to: 1) analyze Landsat satellite images to understand regional vegetation change over the past 30 years; 2) determine the timing of tree establishment as well as the climate influence on tree growth across the forest tundra transition zone over the past 300 years; and, 3. measure spruce seedling growth across the forest-tundra ecotone in relation to varia...

Summary: The goals of this research project are: 1. To fill the information gap on Bathurst caribou summer range conditions using satellite remote sensing data and community-based ground vegetation monitoring 2. To develop a cumulative impact assessment method that makes cumulative impact assessment possible even if data are incomplete and provides timely feedback for guiding the refinement of monitoring...

Summary: The objectives of this project are to draw together multiple sources of information so that the research team may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and int...

Summary: This research project has two primary scientific goals which include: 1) Relating ground truthed snowpack data to passive microwave data obtained from satellites through the winter months. This will assist in formulating a empirical relationship between the two datasets which is necessary to improve satellite monitoring of snow water equivalent. 2) Determining the relative importance of snowmel...

Summary: Environment Canada plans to measure snow depth, snow density and snow water equivalent (water storage in the snowpack), as well as lake ice thickness and structure for comparison with microwave radiometer measurements. Researchers have started to use microwave data from satellites for assessing snow water equivalent (SWE). Field tests to investigate the use of microwave sensors indicate that SW...

Summary: This study is an investigation of massive ice in granular deposits in the Mackenzie Delta area and northeastern North Slave region. The presence of massive ice in aggregate deposits results in resource management problems, particularly for the oil indus...
