Palynology (Mackenzie Valley Global Change), study of the climatic change along the Mackenzie River and on the Arctic Islands.
chercheur principal:
Année(s) de permis: 1995 1993 1992
Résumé: The researcher will sample a variety of lakes (some 50 lakes altogether) around Inuvik. A hole, approximately 8 inches in diameter, will be bored through the ice in each lake. Using an Ekman sampler, lake bottom sediments (mud) will be collected for analysis in the lab. The researchers will get to each of the lakes bt helicopter and spend approximately 15 to 20 minutes at each lake....

Long-term forest-tundra disturbance research
chercheur principal:
Année(s) de permis: 1993 1992 1989 1988 1987
Résumé: In previous research in the 1970's, experiments and surveys provided information on the recovery rates of vegetation in response to disturbances from human activities. Several predictions about the long-term recovery of vegetation were made at that time. We are now collecting data to determine if these predictions reflect what is actually occurring. This information provides information about l...

Arctic timberline ecology
chercheur principal:
Année(s) de permis: 1993
Résumé: As part of his trip to Inuvik with the International Tour of Permafrost Affected Soils, the researcher will record information about the ecology (including local climate conditions, soil conditions and plant communities) of the timberline at selected sites visited during the Tour. These sites are located along the Dempster Highway near Inuvik....

Vegetation Response to Global Warming in the Mackenzie River Basin: Interations Between Northern Boreal Forests, Wetlands and Regional Hydrology
chercheur principal:
Année(s) de permis: 1992
Résumé: 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...

Digital Database of Vegetation Types of the Mackenzie Valley Development Corridor
chercheur principal:
Année(s) de permis: 1992 1991
Résumé: 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...

Reconstruction of post-glacial vegetation and climate in the Inuvik and Tuktoyaktuk area
chercheur principal:
Année(s) de permis: 1988 1987
Résumé: 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....
