Summary: The objectives of this project are: (1) to understand and improve the ability to predict snowcover formation and melt, as well as stream discharge in northern regions, and (2) to understand and improve the ability to predict water levels in the lakes and channels of the Mackenzie Delta. These will allow a better understanding of the impact of climate change and/or natural gas development. In th...

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...

Summary: The primary objective of this project is to improve understanding of the changes in water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek, Hans Creek, and Zed Creek sites will be accessed...

Summary: The researchers are interested in understanding how physical factors (snowmelt, rainfall, solar radiation) play a role in thawing the upper part of the ground each year during the spring and summer. Instruments in the ground will collect data that will estimate how much energy (from the sun) is entering into and melting the frozen ground. Other instruments will measure snowmelt, rainfall and the...

Principal Investigator: Woo, Ming-ko
Licensed Year(s): 1994 1993
Summary: The study attempts to find out how permafrost affects the groundwater, streamflow and levels of water in wetlands. Measurements such as soil moisture, rainfall, ground and air temperatures, and water level will be taken. This research may help to determine the effect of climatic warming on permafrost and water bodies in the arctic....

Principal Investigator: Soulis, E.D. (Ric)
Licensed Year(s): 1992
Summary: The purpose of the project is to improve the ways we have to predict the spring floods in the smaller rivers. Floods from snowmelt are a particular concern in northern rivers. In the Ft. Simpson area, spring flows from the smaller rivers, which are tributaries to the Liard and Mackenzie, have a great deal to do with the timing and nature of breakup on the major rivers. Snow conditions will be surv...

Licensed Year(s): 1993 1992 1991
Summary: The research will study changes in the water levels of a variety of lakes in the Mackenzie Delta. Investigations will include consideration of factors controlling the lake levels, introduction of floodwater from the Mackenzie River, rainfall on to the lake, smowmelt runoff into the lakes and evaporation from the lakes....

Principal Investigator: Wolfe, Alexander P.
Licensed Year(s): 1992 1991 1990
Summary: During the last glacial period, 110,000 to 5,000 years to present some lakes escaped glaciation. The Researcher will retrieve sediment cores from three upland lakes to investigate the physical responses of the sediments and the biological responses of algae toward this climatic event....

Principal Investigator: Heron, Richard
Licensed Year(s): 1993 1990
Summary: Dr. Heron and his assistant will install monitoring devices in snowdrifts which block stream channels. This study will examine these snowdrifts and the way in which they break, since rapid thawing may cause flooding downstream. This project is a continuation of work begun in 1989....

Principal Investigator: Woo, Ming-ko
Licensed Year(s): 1989 1988
Summary: The researcher will be measuring various processes such as snowmelt, meltwater infiltration, refreezing of meltwater and heat conduction into the active layer in order to study their relationships to develop a model linking these processes....
