Glacier mass balance of the Melville South Ice Cap
Principal Investigator: Burgess, David O
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The objective of this research is to characterize the long-term (>50 years) climatic conditions and annual rate of mass change for the Melville ice cap, NWT. Glacier mass balance is defined as the difference between the amount of snow accumulated on a glacier (generally termed winter balance) and the amount lost due to melt (summer balance) over the course of a given year. Due to logistical co...


Investigating the relationship between snow microstructure and airborne synthetic aperature radar measurements of tundra snow to improve environmental prediction capabilities in polar regions
Principal Investigator: Derksen, Chris
Licensed Year(s): 2019 2018
Summary: High resolution Ku-band synthetic aperture radar (SAR) has been proposed to measure Snow Water Equivalent (SWE) from space as part of the proposed Canadian Space Agency Terrestrial Snow Mass Mission (TSMM). An opportunity exists to advance the understanding of the Ku-band radar response to snow properties and develop improved retrieval algorithms using airborne sensors that replicate elements of t...


Relating changes in snowpack water equivalent and structure to migratory behaviour of the Bathurst Caribou herd
Principal Investigator: English, Michael C
Licensed Year(s): 2016
Summary: The objectives are to work with local residents of Wekweeti to understand how changes in the annual snowpack may impact caribou. The idea is that with increased incursions of warm southern air into the subarctic during winter that snow crusts and ice lenses may be created in the snowpack and as a result increase the energy expenditures of the caribou when foraging for food at the base of the snowp...


Airborne SAR and passive microwave measurements over snow covered tundra for CoReH20 retrieval validation and land surface model testing
Principal Investigator: Derksen, Chris
Licensed 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). This would make available high resolution, satellite derived SWE, for monitoring and modeling applications. To-date, airborne measurements to test the CoReH20 satellite mission concept have been ac...


Evolution of the snowpack and snowmelt chemistry in the boreal forest and tundra ecosystem
Principal Investigator: English, Michael C
Licensed 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...


2009 Baseline Studies for Avalon Ventures Ltd. Proposed Thor Lake Rare Earth Metals Project - Surface Water Hydrology
Principal Investigator: Lennie-Misgeld, Peter
Licensed Year(s): 2011 2010 2009
Summary: This licence is being issued for the scientific research application no. 982. The objective of this research is to characterize the surface water hydrology at the Thor Lake site and vicinity for at least one hydrologic year. The baseline study is being conducted to aid Avalon Ventures in assessing potential environmental effects of its activities and having adequate environmental information to...


Variability and Change in the Canadian Cryosphere - Tundra Information Transferability Study
Principal Investigator: Walker, Anne E
Licensed 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...


Hydrological Studies, Mackenzie Delta Region
Principal Investigator: Marsh, Philip
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The objective of this project is to understand water and energy fluxes in northern regions, and to develop improved models of these processes. Project studies will look at both the atmospheric and surface water budgets of the Mackenzie Basin, with an emphasis on the effects of climate change on hydrology. The rates and processes controlling accumulation of snow, snowmelt, water flux through sno...


Airborne passive microwave surveys of the Snare and Yellowknife basins to estimate snow water equivalent
Principal Investigator: Derksen, Chris
Licensed Year(s): 2005
Summary: Regional estimates of snow water equivalent (SWE) are useful for climate studies, calculating how much water is stored in the snowpack, and weather forecasting. These data are available from manual surface measurements, but there not very many measureme...


Snow accumulation/runoff in high latitude permafrost basins
Principal Investigator: Marsh, Philip
Licensed Year(s): 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Summary: The primary objective of this project is to improve understanding of the fluxes of water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek site will be accessed by helicopter and snowmobile...
