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...


Understanding and predicting the impacts of permafrost thaw on water resources and ecosystems
Principal Investigator: Quinton, William L.
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2001
Summary: Understanding the integrated eco-hydrological behaviour of ecosystems in the context of thawing permafrost is a major challenge. To meet this, the research team will measure the present surface and near-surface water supplies and their inter-annual variability assuming a condition of no permafrost thaw. The team will also develop new knowledge on the eco-hydrology of the major ecosystems (i.e. bog...


University of Washington Marginal Ice Zone
Principal Investigator: Lee, Craig
Licenced Year(s): 2014
Summary: The objectives of this research project are to: continue observations of the Arctic Ocean environment; understand the physical environment and processes; and develop integrated air–ice–ocean–wave models for improved prediction. The University of Washington is conducting marine scientific research to study the Marginal Ice Zone (MIZ) in the Beaufort Sea approximately 200 nautical miles west of S...


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) from X- and Ku-band Synthetic Aperture Radar measurements. This would make available high resolution, satellite derived SWE, for monitoring and modeling applications. To-date, airborne measurements ...


Hay River Ice Jam Study
Principal Investigator: Hicks, Faye E
Licenced Year(s): 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004
Summary: The objective of this research project is to study ice processes on the Hay River in order to continue the ongoing development of computer models to predict them. In order to develop realistic models, it is important that the researchers have the opportunity to observe river breakup so as to have a full understanding of the physical context of the historical data. In addition, long term data re...


Noell Lake Ice Study - Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
Principal Investigator: Wrona, Frederick J
Licenced Year(s): 2015 2014 2013 2012 2011 2010 2009
Summary: The overall objective of this research component is to improve knowledge on lake ice and its effect on food webs/productivity in small Arctic lake systems in order to better predict changes that could occur under changing climate. The methodology described here pertains to research activities involving the automated ice buoy and instrumented subsurface mooring system for continuous monitoring o...


Big river wood dynamics in the Canadian subarctic
Principal Investigator: Anderson, Natalie K
Licenced Year(s): 2014 2013 2012
Summary: The Research team proposes to examine the sources of wood within the Mackenzie River drainage, transport of wood toward the Arctic Ocean, and the potential implications of global warming for wood recruitment and transport. The primary objectives are to (i) evaluate fundamental controls on wood dynamics within the Mackenzie and (ii) develop an empirical predictive model to estimate future wood dyna...


O-buoy measurements of ozone, carbon dioxide and bromine oxide over frozen surface of Hudson Bay and Arctic Ocean
Principal Investigator: Bottenheim, Jan W
Licenced Year(s): 2012 2011 2010
Summary: The goal of this project is to take part in establishment of a long-term observation network to measure concentrations of two important greenhouse gases (ozone and carbon dioxide) as well as bromine oxide. Bromine oxide is a key chemical reagent determining the presence of ozone accompanied with full set of meteorological data and detailed geographic information across the Arctic Ocean and Hudson ...


Paleoclimatological assessment of the central Northwest Territories: implications for the long-term viability of the Tibbitt to Contwoyto winter ice road
Principal Investigator: Patterson, R. Tim
Licenced Year(s): 2012 2011 2010
Summary: Through analysis of sediment/water interface samples, freeze cores, and dendrochronology the researchers intend to: i) develop a comprehensive climatic history along a 2° latitudinal gradient in the central NT, variously based on an analysis of freeze cores from lakes along the route of the Tibbitt to Contwoyto Winter Road (TCWR); ii) determine the relationship between modern lake catchments an...


North Slave Permafrost Study: Characterizing and Predicting Discontinuous Permafrost for Climate Change Adaptation
Principal Investigator: Wolfe, Stephen A
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010
Summary: This activity will describe and predict the occurrence of discontinuous permafrost in the northern Great Slave Lake region to assist in planning, development and maintenance of community and industry infrastructure. Future changes in climate will affect permafrost distribution, temperatures and geotechnical conditions. It is anticipated that different landscapes across the region will exhibit vary...
