Remote sensing of Arctic-Boreal surface water
Principal Investigator: Smith, Laurence C.
Licenced Year(s): 2017
Summary: The goal of this project is to measure variations in water surface elevation, inundation extent, permafrost presence/absence, active layer thickness, soil moisture and related variables for lakes, wetlands and rivers in four primary study areas within the Northwest Territories (NWT). Using ground measurements combined with maps of water surface elevation produced by the Air Surface Water and Ocean...


Hydrological Remote Sensing
Principal Investigator: Berg, Aaron A
Licenced Year(s): 2017
Summary: This research has two main objectives: 1) to monitor the spatial variability of soil moisture at the scale of a Soil Moisture Active Passive (SMAP) 36km pixel centered around the Trail Valley Creek (TVC) watershed; and, 2) to evaluate the current soil moisture algorithms and products currently utilized by SMAP. To achieve the first objective, the research team will install soil moisture monit...


Permafrost in the western Arctic
Principal Investigator: Kokelj, Steve V
Licenced Year(s): 2017 2016
Summary: The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and, 3) to assess the physical and chemical characteristics of permafrost. To achieve the objectives the r...


Radar Remote Sensing of Snow
Principal Investigator: Kelly, Richard
Licenced Year(s): 2017
Summary: The primary objectives of this study are to: 1) understand and explain the role of snow microstructure in terms of the radar backscatter and phase response in this environment; 2) to evaluate the efficacy of differential synthetic aperture radar (dInSAR) for snow accumulation estimates at C-band; and 3) to evaluate the optimal approach to estimating snow water equivalent using radar from this site...


Hydrological Remote Sensing
Principal Investigator: Berg, Aaron A
Licenced Year(s): 2016
Summary: The main objectives of this research are to: 1. monitor the spatial variability of soil moisture at approximately a 10km resolution in the region of Trail Valley Creek (TVC); and, 2. to test the soil moisture retrieval algorithms in high organic soils through both satellite based measurements and with the use of a ground based radiometer. To achieve the first objective, the research team will...


Water Ecosystem Monitoring using Earth Observations
Principal Investigator: Chamberland, Joseph
Licenced Year(s): 2016 2015
Summary: The research project Water Ecosystems Monitoring using Earth Observation aims to define an Earth Observation (EO) driven monitoring program to provide information towards monitoring environmental indicators of northern ecosystem health. Once the project is done information on water indicators including water temperature, suspended sediment concentrations, water levels, and ice quality and will be ...


Evolution of the snowpack and snowmelt chemistry in the boreal forest and tundra ecosystem
Principal Investigator: English, Michael C
Licenced Year(s): 2012 2010 2009 2008 2007 2006 2005 2004
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...


Understanding and prediction of permafrost thaw impacts on northern water resources
Principal Investigator: Quinton, William L.
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2001
Summary: The long-term goal of this research project is to develop a suite of models for predicting the response of discontinuous permafrost in the Hay River Lowland to climate warming and human disturbance from oil and gas exploration, and the consequent change in landcover and river flow regime. This will be achieved by meeting the following short-term objectives: 1) map the spatial distribution of perma...


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...


Variability and Change in the Canadian Cryosphere - Tundra Information Transferability Study
Principal Investigator: Walker, Anne E
Licenced Year(s): 2008
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...
