Dehcho Indigenous Community Based Climate Change Monitoring
Principal Investigator: Low, Mike
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4812. The objective of this project is to increase collection of climate change indicators, while also training Dehcho Guardians to collect the same data independently in the future. This information in addition to the collection of traditional knowledge will show changes to the environment and the data can be used to prote...


Geological carbon in the Mackenzie River Basin: Sources and sinks of atmospheric carbon dioxide
Principal Investigator: Hilton, Robert G
Licensed Year(s): 2017 2013 2011 2010 2009
Summary: The overall aim is to assess the carbon balance of the Mackenzie River Basin and to place constraints on the role of climatic and physical erosion processes in driving carbon dioxide source and sinks to the atmosphere and oceans. More specifically, the researchers aim to quantify the amount of chemical weathering that takes place in the Mackenzie River Basin; to quantify how much weathering of sil...


Search for Springs Reported by McConnell in 1890
Principal Investigator: Grasby, Stephen
Licensed Year(s): 2005 2004
Summary: This project is a continuation of work begun in 2004. The researchers were not able to do their field work in 2004, and will try again in 2005. Historic mention is made of springs at Windy Point on the north shore of Great Slave Lake. The research team...


Investigation of factors affecting high mercury levels in fish in lakes in the Mackenzie River Basin (2002-2003)
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2003 1998
Summary: This study is based on earlier research conducted by the Department of Fisheries and Oceans which found that fish in many lakes in the Mackenzie River Basin had high mercury concentrations. This study examines the environment in which the fish live in o...


Investigating the Importance of Water Chemistry on Mercury Concentration in Fish from Mackenzie River Basin Lakes
Principal Investigator: Stephens, Glen
Licensed Year(s): 1998
Summary: The objective of the work is to characterize the water chemistry of lakes with reported elevated concentrations of mercury in fish from the Mackenzie River Valley, which were sampled as part of the Department of Fisheries & Oceans (DFO) fisheries management plan. This would help to establish if there is any relationship between basic lake water chemistry and mercury levels in fish which could be u...


Vegetation Response to Global Warming in the Mackenzie River Basin: Interations Between Northern Boreal Forests, Wetlands and Regional Hydrology
Principal Investigator: Nicholson, Barbara
Licensed Year(s): 1992
Summary: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...


The Hydrogeology and Deposition of the Rabbitkettle Hotsprings and Tufa Mounds, Nahanni National Park, N.W.T.
Principal Investigator: Gulley, Angela L.
Licensed Year(s): 1992 1991
Summary: The Researcher will: map the local geology adjacent the hotsprings; conduct a geochemical analysis of the springwaters; monitor the physical properties (pH, temp.); calculate natural discharge rates, conduct a pumping test and monitor depositional rates of tufa accumulations....


Licence #2459
Principal Investigator: Smith, Daniel W.
Licensed Year(s): 1979
Summary: To sample treated and untreated domestic water supplies for physical and chemical analysis, (e.g. turbidity, color, temperature and trace elements analysis, e.g. lead, zinc, silver and cadmium)....
