Principal Investigator:Marsh, Philip Licenced Year(s):
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) consider the integrated effect of climate on vegetation, snow, permafrost, streamflow, and lakes, and 3) develop improved predictive tools or models. These will allow a better understanding of the impact of climate ch...
Principal Investigator:Quinton, William L. Licenced Year(s):
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...
Principal Investigator:Lee, Craig Licenced Year(s):
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...

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 ...

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...

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...

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...
Principal Investigator:Bottenheim, Jan W Licenced Year(s):
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 ...
Principal Investigator:Patterson, R. Tim Licenced Year(s):
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...

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...
