Summary: The main goal of this research is to use lake sediment records to examine changes in weather conditions and river discharge in the western Canadian Arctic during the past 2000 years, which will aid in understanding current conditions and forecasting future conditions. The research team will reach the study location by airplane from Resolute, Nunavut, and will be on site from late May to early ...

Summary: The Beaufort Sea shelf is very shallow and the Mackenzie River, which sends freshwater, nutrients, and particles onto the shelf, may have a large influence on its productivity. The researchers would like to study the effects of the river in transporting particles to the shelf by measuring the types of particles, how fast they sink, and how easily they are stirred from the bottom. They would also ...

Summary: The primary objectives of the project are to; 1) monitor coastal stability and the processes which affect it (winds, waves, sea ice, etc); 2) map coastal features, sediment properties, and ice conditions in the nearshore regions of the Mackenzie Delta an...

Summary: Evaluation of the strength of methane emissions from lakes in the Mackenzie Delta relative to lakes on the adjacent arctic tundra. Will involve collecting water and sediment samples from 27 lakes in the Mackenzie Delta near Inuvik and from an additional 27 lakes located within the Havik Pak Creek and Trail Valley Creek study basins. Evaluation of diatom (algae) communities as predictors of flood...

Principal Investigator: Schunke, Ekkehard
Licensed Year(s): 2000 1994 1992 1990
Summary: The researchers will continue their study, initiated in 1990, on the geological and hydrological processes which contribute to valley formation in the subarctic and arctic. Data will be collected on various aspects of water runoff and sediment content. This data, along with long-term environmental data collected by Environment Canada, will contribute to our knowledge about valley formation....

Principal Investigator: Burn, Chris R
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991
Summary: The researcher will continue to collect samples of ground ice and measure temperatures in lakes and ponds. This information is used to help understand how the ground heaves as it freezes in winter, and to determine the extent of soil settlement during thaw in summer. The information about lakes is used to help understand the relations between water depths and temperatures beneath the lake....

Principal Investigator: Jasper, Jesse
Licensed Year(s): 1993
Summary: The researchers will work in collaboration with other scientists to study water and sediment characteristics at certain Inland Water Directorate sites in the Mackenzie Delta. This study will be useful for evaluating impacts of hydrocarbon development as well as delta flooding on water flow, wildlife and vegetation in the delta. In addition, contaminants in water and sediments will be measured....

Principal Investigator: Marsh, Philip
Licensed Year(s): 1993 1992 1991
Summary: This long-term, ongoing study is aimed at understanding the factors controlling water levels and the availability of nutrients in a variety of lakes in the Mackenzie Delta. This work will allow us to better understand the natural Mackenzie Delta ecosystem, and to make better predictions of the effect of environmental change on the Delta. Cores of sediment will be collected from lake bottoms to d...

Principal Investigator: Fassnacht, Steven
Licensed Year(s): 1992
Summary: At both the East Channel (Mackenzie Delta) and at Cabin Creek the elevation at various cross-sections will be measured so that a detailed contour map may be plotted. River bed material will be sampled to determine the size distribution of the bed material....
