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....

Principal Investigator: Fassnacht, Steven
Licensed Year(s): 1992
Summary: The research will involve travelling from the upper delta in the Peel and Esau Channel area to the lower Mackenzie Delta in the Taglu and Niglintgak area. The cross-section depth of various channels will be measured using a depth-sounder measuring device affixed to the stern of the boat....

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...

Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1992 1991 1991 1990
Summary: Snow samples will be collected from approximately 30 sites across the NWT and Yukon in the spring of the year. This annual snow pack sample will allow an estimate of the quantity of organic contaminants that have been deposited over the winter season. To better understand the fate of these contaminants in the High Arctic, the researchers will undertake an intensive small basin study on Cornwallis ...

Principal Investigator: Fyles, John G.
Licensed Year(s): 1992 1991 1990
Summary: On Melville and Bathurst Islands, the Researchers will locate and describe the occurrence of high-level gravels and sands, record evidence of the flow-direction of the rivers in which they originated and search for plant and insect fossils that may provide clues about the age of these deposits and about the climate and environment at that time....

Principal Investigator: Forbes, Donald L
Licensed Year(s): 1991 1990
Summary: The Researchers will use the ARKTOS 5 amphibious vehicle for geophysical surveying in the vicinity of Tuktoyaktuk and the proposed Amauligak pipeline landing site on Richards Island. They will measure nearshore sediment dynamics using wave and current meters at selected locations in the vicinity of the proposed pipeline landing site at North Head....

Principal Investigator: Erickson, Dave
Licensed Year(s): 1991
Summary: The Researcher and his team will carry out a project to improve water flow studies, channel dredging, mapping and local construction surveys....

Principal Investigator: Melling, Humfrey
Licensed Year(s): 1996 1995 1994 1993 1992 1991 1990
Summary: Dr. Melling and his research team will continue to study ice in the Beaufort Sea. Sonar instruments will be deployed at two locations, will operate at 50-80m depth and be recovered in April, 1991. They will also survey seawater properties at selected sites offshore. This is the eighth year the seawater survey has been conducted in the Beaufort Sea in late winter....

Principal Investigator: Dean, Ken
Licensed Year(s): 1991 1990
Summary: Satellite imagery, hydrologic data and field measurements will be used to develop a computer model of the thawing of sea ice and freezing of water in this area. The investigators will drill a hole through the ice and measure water temperature, salinity and turbidity....
