Vegetation Survey for the Ikhil Gas Development
chercheur principal: Sutor, Greg
Année(s) de permis: 1997
Résumé: Vegetation communities along the pipeline route and over other parts of the Project area would be provisionally mapped from aerial photographs. A field survey would be undertaken with an emphasis on identifying rare plants. The study area is in the Caribou Hills IBP site 4-9, which was in part proposed because of its rare flora. July is an optimum time for a single survey. Also transect sampling ...


Studies of the Environmental Effects of Disturbances in the Subarctic (SEEDS)
chercheur principal: Kershaw, G. Peter
Année(s) de permis: 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Résumé: Access to the site will be along existing seismic lines from Tulita. Transport will involve helicopter, boat, ATV and foot. The research is planned to see what happens after the fire to the permafrost, soils, plants and animals. An unburned site will be monitored to provide comparison with the burned area. Many studies will be done, including measurements of air and soil temperatures, wind spe...


Ice scour disturbance and the structure of arctic marine benthic communities
chercheur principal: Conlan, Kathleen E.
Année(s) de permis: 1994 1993 1992
Résumé: The researchers will investigate the effect that sea ice has on shaping and scouring the sea bottom since these actions may play a major role in determining the sea bottom environment and the types of plants and animals that may live there. They will revisit the 1992 site in order to determine what new scours have appeared: those locations with fresh scrapes on the bottom will be monitored over t...


A Re-evaluation of Disturbance Research in the Tundra near Tuktoyaktuk
chercheur principal: Wein, Ross
Année(s) de permis: 1993 1992 1989 1988 1987
Résumé: The research will document long-term recovery rates on permanent research plots that were established on a range of tundra disturbances. In the 1970's disturbance surveys and experiments on a wide range of topics provided short-term results and predictions on recovery rates. This project will collect comparable data to validate these short term predictions and will also help to develop some ideas ...
