Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4727. The research team will use lake sediment cores to track the history of shoreline permafrost thaw slump activity over the last several thousand years, and associated lake ecological responses to thaw slumping, in order to provide a long-term context for present-day observations. The team will select three pairs of ...

Principal Investigator: Quinton, William L.
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4726. The specific scientific objectives are to: 1) develop fundamental knowledge of the major ecosystems and estimate the amount of water present. The watershed responses to changes in permafrost and the rate and trajectory of such changes will also be examined; 2) develop and test a new suite of hydrological predictive to...

Summary: Understanding the ecology and hydrology of ecosystems with thawing permafrost is a major challenge. To meet this, the research team will develop new knowledge on the eco-hydrology of the major ecosystems (i.e. bogs, fens, peat plateaus) needed to develop new science-based tools to predict the future supply for the next 50 years. The specific scientific objectives are: 1) Develop fundamental knowl...

Licensed Year(s): 2019
Summary: The objectives of this research is to: 1) determine if thaw slumping results in the loss of a large-bodied zooplankton species (Daphnia) from lakes; and 2) measure polychlorinated biphenyl concentrations in lake sediments near the Distant Early Warning Line site in Tuktoyaktuk, to assess whether legacy contamination is still evident. The research team will be collecting sediment cores from ...

Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2017
Summary: The research team will re-survey 70 lakes originally sampled in 2005/06, to assess how conditions have changed in the intervening decade as thaw slumping has intensified and the Inuvik-Tuktoyaktuk Highway (ITH) was constructed. The team will assess how lake ecosystems responded to past climatic shifts throughout the post-glacial history of these lakes (10,000 years), and use these records to provi...

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...

Principal Investigator: Blais, Jules M
Licensed Year(s): 2014
Summary: The objectives of this research project are: 1) to determine the impact of shoreline expansion and forest/peat submergence from thawing permafrost on contaminant and carbon fluxes to lakes in the Yellowknife region; 2) to develop novel approaches to track terrestrial organic matter sources in lakes, in order to assess how climate warming and permafrost thaw are affecting the delivery of terrestr...

Principal Investigator: Dallimore, Scott R
Licensed Year(s): 2017 2014 2013
Summary: The agencies involved are undertaking this research to acquire geoscience knowledge about the outer shelf of the Beaufort Sea with intent to address knowledge gaps related to thawing of subsea permafrost and gas hydrates. The research will be made publicly available to northern communities, regulators, the scientific community and industry through the release of scientific papers, maps and reports...

Principal Investigator: CLARK, Ian D.
Licensed Year(s): 2011 2010
Summary: The main goal of this project is to determine the distribution, nature and origin of thaw flows and the associated massive ground ice bodies in Fort McPherson region, Northwest Territories. This study will use sedimentological analyses and radiocarbon datation to determine the nature and age of sediment in which massive ice is included. Radardsat 2 image from the summer 2009 will be used to eva...
