Hydrology of High Latitude Watersheds
Principal Investigator: Marsh, Philip
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The objectives of this project are: 1) to develop improved understanding of, and ability to predict, snowcover formation and melt, as well as stream discharge in northern regions, 2) to consider the integrated effect of climate on vegetation, snow, permafrost, streamflow, and lakes, and 3) to develop improved predictive tools or models. These will allow a better understanding of the impact of clim...

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...

Thermal State of Permafrost
Principal Investigator: Siegfried, Dian
Licenced 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
Licenced Year(s): 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
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). 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
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...

Mass Balance of Arctic Glaciers and Arctic Pollution
Principal Investigator: Koerner, Roy M
Licenced 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.
Licenced 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
Licenced 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
Licenced 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...
