Environmental Soil Chemistry at Abandoned Drilling Mud-Sumps in the Kendall Island Bird Sanctuary, Mackenzie Delta Region
chercheur principal: Biggar, Kevin
Année(s) de permis: 2006 2005
Résumé: Since the 1970s, the oil and gas industry has drilled at least nineteen exploratory wells in the Kendall Island Bird Sanctuary. Observations at associated drilling mud-sumps have been made; however, there remains a paucity of field data describing site conditions. It is also appreciated that construction of the proposed Mackenzie Valley pipeline will stimulate the development of Niglintgak and Tag...


Biocomplexity of frost-boil ecosystems
chercheur principal: Walker, Donald A
Année(s) de permis: 2006 2005 2004 2003
Résumé: The goal of this project is to understand the complex linkages between biogeochemical cycles, vegetation, disturbance and climate across the full summer temperature gradient in the Arctic in order to better predict ecosystem responses to changing climate...


Ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT.
chercheur principal: Kershaw, G. Peter
Année(s) de permis: 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Résumé: The main study objectives are to: 1) determine the status of permafrost landforms in the study area, and 2) determine long-term recovery after abandonment of the CANOL No. 1 project. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond the base camp mountain bikes and foot will be the means of transport. Automated microclimate stations powered by solar ene...


Long-term forest-tundra disturbance research
chercheur principal: Wein, Ross
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...


An Examination of Disturbance to Plant Communities on Truelove Lowland, Devon Island, N.W.T.
chercheur principal: Hewitt, Nina
Année(s) de permis: 1991
Résumé: The Researcher will carry out field work in association with Dr. Cheryl M. Pearce. The research will measure the nature and extent of human disturbance within the dominant plant communities on Truelove Lowland and attempt to correlate the disturbance with species composition, surficial materials, and the type of disturbance....


Recovery of High Arctic Vegetation from Disturbance by Human Occupation
chercheur principal: Forbes, Bruce C.
Année(s) de permis: 1990 1988
Résumé: Bruce Forbes is looking at how quickly plants are invading the old settlement of Clyde River where the ground was cleared for buildings and roads. This site will be compared to undisturbed ground and similar disburbances at other human occupancy sites within the High Arctic....

chercheur principal: Fairbarns, Matt
Année(s) de permis: 1984
Résumé: To choose study sites for work to be done next Spring on investigation of vegetation-permafrost-microclimate relationships associated with subarctic pipeline disturbances....

chercheur principal: Kershaw, G. Peter
Année(s) de permis: 1979
Résumé: To evaluate the impacts of the Canol Project (1942-45) upon the topography and plant communities and to determine the natural rehabilitation of disturbed sites....
