Principal Investigator: Cohen, Stewart
Licensed Year(s): 1993 1992
Summary: The Mackenzie Basin Impact Study will assess the potential impacts of global climatic change on the region. The component on land assessment will determine possible changes in land capability. Information on resource management goals is needed so that the study can can assess whether changes in land capability might lead to conflicts over land use....

Principal Investigator: Aharonian, Dave
Licensed Year(s): 1992
Summary: The researcher will examine the ability of an aboriginal community to adapt to climate change by documenting past events which have been influenced by the climate. These events will be probed through the oral histories of the community members, especially elders. The views and perceptions as held by the community members, concerning future changes in climate will be determined....

Principal Investigator: Hart, Elisa J.
Licensed Year(s): 1995 1994 1993 1992 1991
Summary: The researcher and her team will document the early history of the reindeer herding industry, conduct interviews with elders to obtain information on the location and nature of traditionally used places and gain insights into aspects of traditional technology that are of benefit to archaeological interpretation. As well, traditional knowledge of climate change will be examined through interviews ...

Principal Investigator: Olsen, Sue K.
Licensed Year(s): 1992
Summary: The experiment will determine the interacting effects of fire severity, soil moisture and air temperature treatments on the emergence, winter survival and initial growth of treeline and near treeline tree species. The availability and viability of tree seed for successful regeneration of the treeline and near-treeline tree species will also be determined....

Principal Investigator: Landhaeusser, Simon M.
Licensed Year(s): 1992 1991 1990
Summary: To determine the maximum size of treeline tree species in a burned and unburned valley in the Caribou Hills, the mass of standing trees on different slopes and aspects will be estimated and related to the energy input. In 1992 the plots prepared in 1990 and planted and seeded in 1991, will be revisited and measurement of growth for the second growing season will be taken....

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: Tarnocai, C.
Licensed Year(s): 1991
Summary: This tour and the associated meetings will focus on the genesis, classification and management of permafrost soils (Cryosols) and the possible effect of climate change on these soils....

Principal Investigator: Pearce, Cheryl M.
Licensed Year(s): 1993 1992 1991 1990
Summary: The Researcher will continue to determine what density of trees is necessary for detection by the satellite sensors. To determine what are the densities of shrubs and herbs or dwarf shrubs and lichens that change the reflectance patterns from the understory. To determine if the thresholds in density will be sensitive enough to monitor vegetation responses to climate change in the forest to tundra ...

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....

Principal Investigator: Jacoby, Jr., Gordon C.
Licensed Year(s): 1984
Summary: To collect core samples from trees for later annual ring studies that will provide information on the climate during the history of the tree....
