Soil Climates of the Mackenzie Valley
chercheur principal:
Année(s) de permis: 1994
Résumé: Soil (at seven depths) and air temperature data are recorded by data loggers. These loggers are programmed to collect data every 3 hours on the hour. The sites are visited twice a year to reprogram the loggers. In addition, active layer depth and subsidence are also recorded during the fall visit. Researchers will collect this data in order to determine the effect of climate change on the envi...

Forest & Forest Fire Studies in the Mackenzie Delta Ecosystem
chercheur principal:
Année(s) de permis: 1994
Résumé: Since fire is most wide spread agent of change in the northern forest, society should know how climatic warming will influence the force. The fire history of the Mackenzie Delta Region is known only through fire suppresion records over the past 25 years. Spot checks on the landscape have been made, but no longer record of 5-20 decades is available. Tree ring approaches will be used in this study...

Investigation of ground ice development in sediments of the Mackenzie Delta area
chercheur principal:
Année(s) de permis: 1997 1996 1995 1994 1993 1992 1991
Résumé: The researcher will continue to collect samples of ground ice and measure temperatures in lakes and ponds. This information is used to help understand how the ground heaves as it freezes in winter, and to determine the extent of soil settlement during thaw in summer. The information about lakes is used to help understand the relations between water depths and temperatures beneath the 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...

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 ...

Lower Mackenzie Valley archaeological survey and Arctic Red River archaeological excavation
chercheur principal:
Année(s) de permis: 1993
Résumé: The researchers will conduct archaeological surveys and excavations at seven locations along the Mackenzie River: six sites will be surveyed and the seventh site, located at the confluence of the Arctic and Mackenzie Rivers, will be excavated. Licence issued for use of Inuvik Research Centre....

Structural and stratigraphic analysis of the northern Yukon and Beaufort-Mackenzie region
chercheur principal:
Année(s) de permis: 1993 1991 1987
Résumé: The field component of this project consists of examination of exposures of bedrock during ground surveys (on foot) at selected sites. This work will produce a geological map showing rock types, ages and positions as well as the degree to which the layers of rock have been folded or faulted during times in which mountains were formed. Licence issued for purposes of using the Inuvik Research Cent...

Riverine inputs of contaminants to the Arctic Ocean
chercheur principal:
Année(s) de permis: 1993
Résumé: Northward flowing rivers are thought to be major ways in which contaminants are introduced to the Arctic Ocean. As part of an on-going study, river water and sediments will be collected over the course of the year and assessed for the presence of contaminants. A total of 12 rivers in the Canadian arctic mainland will be sampled in this study, including the Mackenzie, Coppermine, Burnside, Ellice...
