Effects of global warming on settlements and non-renewable resource development in the Mackenzie Basin to the year 2050
chercheur principal:
Année(s) de permis: 1994
Résumé: Should global warming occur, the environment and human landscape may be altered. The researchers will be using public information (Statistics Canada censuses and public documents) to collect data for this study: they will use this data to examine the possible impacts that global warming might have on the Mackenzie Basin ecosystem and the human population residing in this region. The results of ...


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...


Climate change and postglacial paleoenvironmental history of peatlands in the Mackenzie Delta area
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: This research is part of an international project that is aimed at documenting the history of changes in the treeline during the Holocene era. While much is known about the environment and climate of this era, little is known about the development of peatlands during this time. I will collect data on peat layering, pollen and fossils in order to determine how the peatlands developed during this ...


Post-glacial treeline change in the Campbell-Dolomite Uplands of the Inuvik area
chercheur principal:
Année(s) de permis: 1993
Résumé: As part of an on-going study, this research will involve collecting cores from trees located in the Campbell-Dolomite Uplands (near Campbell Lake). This data will be added to data collected in other locations (past studies) in order to determine how past climate has influenced the growth of trees (as indicated by tree rings within the tree trunk). The research is helpful in trying to understand ...


Implications of climate change for slope stability in the Mackenzie Valley
chercheur principal:
Année(s) de permis: 1993
Résumé: In this ongoing study, the frequency and characteristics of landslides occurring in the Mackenzie Valley area are examined. I am trying to determine the roles that forest fires, climate changes and water flow in rivers play in the location and number of landslides. The field work will involve taking measurements on past landslides that include measuring permafrost features and taking core samples...


Mackenzie Basin Impact Study: Land Assessment
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: 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....


Impacts of Climate Change upon the Community of Aklavik, NWT
chercheur principal:
Année(s) de permis: 1992
Résumé: 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....


Tuktoyaktuk Traditional Knowledge Project and Traditional Knowledge of Climate Change
chercheur principal:
Année(s) de permis: 1995 1994 1993 1992 1991
Résumé: 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 ...


Fire Severity and Growth of Treeline Tree Species: Climate Change Implications
chercheur principal:
Année(s) de permis: 1992
Résumé: 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....


Peat Plateau Collapse and Climate Change
chercheur principal:
Année(s) de permis: 1992
Résumé: The research will examine permafrost-containing peat plateaus that have burned during severe fires to determine the features of subsidence (decrease) and the rate of subsidence....
