Summary: This ongoing project examines how vegetation has changed in response to changes in climate. I am using the history of vegetation, as recorded by the fossilized pollen that is present in lake sediments, to determine how vegetation in the arctic has changed over thousands of years. Fossilized pollen is collected by taking core samples from lake bottoms on Prince of Wales and Bathurst Islands. Pre...

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: Viren, Tom
Licensed Year(s): 1991
Summary: Mr. Lonnie Dupre, Mr. Malcolm Vance and Mr. Jon Nierenburg will collect snow and plant material samples on behalf of Mr. Derik Muir, Department of Fisheries and Oceans, Canada and Mr. Dan Jaffe, Geophysical Institute, University of Alaska, Fairbanks....

Principal Investigator: Squires Taylor, Cindy
Licensed Year(s): 1992 1991
Summary: The Researcher will conduct a survey, approximately 30 km on either side of the Mackenzie River using satellite imagery. A classification will be undertaken of the area from the Mackenzie Delta to the Fort Simpson area, with wider zones along the east side to include proposed pipeline routes. The information can be plotted as colour maps to show the location of trap lines, forest fires or wildlife...

Principal Investigator: Scotter, George
Licensed Year(s): 1990
Summary: The Researcher and team will carry out this survey at the request of the community of Paulatuk. They will summarize the existing knowledge of the natural resources of the Bluenose Lake Region. A total of about 20 stops will be made to examine the vegetation, soil, wildlife and physiogeography and to collect plant and soil samples....

Principal Investigator: Ritchie, J.C.
Licensed Year(s): 1988 1987
Summary: Dr. Ritchie is looking at live plants and the remains of plants at the bottom of lakes to see how plants and weather have changed since the glaciers left the Inuvik and Tuktoyaktuk area 10,000 years ago....

Principal Investigator: Howland, William G.
Licensed Year(s): 1987
Summary: To continue the study of plants and landforms, including areas of landslide, in the Caribou Hills. To examine the plants that have revegetated, to observe what species seem most capable of natural revegetation and how much erosion or plant growth has developed in 10 years. To prepare a species list for plants near the East Channel....

Principal Investigator: Ritchie, J.C.
Licensed Year(s): 1985
Summary: April - to take 5 cm diamete rcores of unconsolidated lake mud from 6 small lakes; July - to conduct a survey of the vegetation surrounding the lakes sampled in the above winter coring operation....

Principal Investigator: Ritchie, J.C.
Licensed Year(s): 1981
Summary: (a) To collect a series of lake sediments; (b) To collect selected plant groups and conduct vegetation analysis....

Principal Investigator: Hutchinson, Tom
Licensed Year(s): 1980
Summary: To continue a study of the effects of acid fumes (Smoking Hills) on land and water vegetation. Soil samples will be collected for future lab analysis. Oil spill sites will also be revisited and monitored....
