Thermal State of Permafrost
Principal Investigator: Siegfried, Dian
Licensed Year(s): 2016 2013 2010
Summary: The objective of this project is to continue an ongoing long-term monitoring of permafrost temperatures on Banks Island and Mould Bay. At these sites the research team have lost remote (satellite) communication and need to make repairs to continue receiving data. The research team are currently monitoring active layer and permafrost temperatures, active layer soil moisture, air temperature, and...


Melville Island South Ice Cap Mass Balance & Snow Pollution
Principal Investigator: Burgess, David O
Licensed Year(s): 2023 2022 2021 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: By measuring the changing volume of the ice cap and maintaining an Automatic weather station the research team is able to tell how much the climate is changing. The snow sampling tells how clean the snow and air above it is and whether or not it is changing. While at the Melville ice cap, the team lives in a small hut by the side of the ice cap constructed last year. There is an automatic weath...


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...


Mass Balance of Arctic Glaciers and Arctic Pollution
Principal Investigator: Koerner, Roy M
Licensed Year(s): 2008 2007 2006 2005 2004 2003
Summary: The objectives of this ongoing research project are: (a) to monitor climate change by measuring the changing volume of the ice cap and maintaining an automatic weather station, and (b) to monitor air and snow pollution by sampling snow and sending it to be analyzed. Based out of the Polar Continental Shelf Project in Resolute Bay, NU, two personnel will fly by Twin Otter to the ice cap, and liv...


Active Layer Monitoring Network in the Mackenzie Valley – Snow Monitoring Component
Principal Investigator: Nixon, Fredrick M.
Licensed Year(s): 2008
Summary: The objective of this project is to conduct snow surveys at selected sites in the Mackenzie Delta, related to permafrost studies. Snow surveys will be carried out at three selected sites in the Delta during early April. These are Circumpolar Active Layer Monitoring Program sites. There is a grid marked on these locations, where the researchers will be measuring the snow pack and snow density. M...


Active Layer Monitoring Network in the Mackenzie Valley
Principal Investigator: Nixon, Frederick M
Licensed Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...


Relations between snow, near-surface ground temperatures, and ground ice, Kendall Island Bird Sanctuary, Mackenzie Delta, NWT
Principal Investigator: Morse, Peter D
Licensed Year(s): 2008 2007 2006
Summary: The purpose of this project is to complete the determination of the variation and distribution of near-surface ground ice at Kendall Island Bird Sanctuary (KIBS) begun in 2006. The aim is to collect ground ice samples along previously established vegetation and snow courses within distinct terrain units and transition zones, and to determine the relations between ground ice configuration and the s...


Investigations of the water cycle and hydrological processes of the subarctic Canadian Shield
Principal Investigator: Spence, Christopher
Licensed Year(s): 2017 2016 2012 2011 2010 2009 2008 2007
Summary: The objective of the research is to determine the water cycle processes in lakes and streams affecting Baker Creek and similar streams, and more generally to understand how small scale processes influence those of larger areas. Field studies at Baker Creek, a typical Canadian Shield stream that drains ~130 km2 into Great Slave Lake, will focus on the spring melt and summer seasons. Existing i...


Examining Spatial and Temporal Variation of Ground Temperatures in the Mackenzie Delta, Northwest Territories
Principal Investigator: Kanigan, Julian
Licensed Year(s): 2007 2006
Summary: The Mackenzie Delta is sensitive to both climate warming and human development. This project will contribute to a better understanding of ground temperatures in the Mackenzie Delta and will provide a baseline from which to assess future changes and cumulative impacts. Ground temperatures will be collected from the southern, central and outer delta regions. In the summer, about 30 boreholes (l...
