Vegetation Responses to the Acidic Sulfur fumes at the Smoking Hills, Cape Bathurst.
Principal Investigator: Hutchinson, Tom
Licenced Year(s): 1999
Summary: The purpose of this study is to re-measure the occurrences of vegetation, identifying all the different species and measuring them quantitatively in places that were measured 13 years ago. The focus this time will be on the ability of the tundra ecosystem to recover when a strong chemical stress ceases. The team will be flown in early August from Inuvik to the old DEW Line landing strip at Mallo...


Licence #4092
Principal Investigator: Hutchinson, Tom
Licenced Year(s): 1984
Summary: To continue studies of the Smoking Hills into the nature of the adaptations by which aquatic biota and tundra plants survive the intense acidic fumigations from the burning cliffs. Focus will be on the algae and zooplankton of tundra ponds and samples will be taken for identification by microscopic study on the spot and others preserved for later identification....


Licence #2601
Principal Investigator: Hutchinson, Tom
Licenced Year(s): 1980
Summary: To continue a study of the effects of acid fumes (Smoking Hills) on land and water vegetation. Soil samples will be collected for future lab analysis. Oil spill sites will also be revisited and monitored....


Licence #2349
Principal Investigator: Hutchinson, Tom
Licenced Year(s): 1978
Summary: A continuing study of the impact of natural lignite burning on the land and marine environment....


Licence #2121
Principal Investigator: Hutchinson, Tom
Licenced Year(s): 1977
Summary: To determine the degree of recovery of crude oil spills made in 1972 and 1973 on taiga at Norman Wells and tundra at Tuktoyaktuk. To determine the effects of a 1975 diesel oil spill on taiga at Norman Wells and to compare the effects with crude oil spills made in comparable terrain. To examine the pattern of vegetational recovery of these areas. To examine the effects of crude oil spills made o...


Licence #2120
Principal Investigator: Hutchinson, Tom
Licenced Year(s): 1977
Summary: To develop a practical and economic method of revegetation of "difficult" tailings and mine sites in the N.W.T., using acid and metal tolerant vegetation growing naturally at the highly stressed Smoking Hills area of Cape Bathurst, N.W.T....


Licence #1962
Principal Investigator: Hutchinson, Tom
Licenced Year(s): 1976
Summary: To examine revegation of northern tailings and mining areas using materials from an acid-heavy metal stressed Arctic area....


Licence #1894
Principal Investigator: Hutchinson, Tom
Licenced Year(s): 1975
Summary: To ascertain how crude oil affects terrestrial and aquatic plants, and soil and water micro-organisms, for Arctic Land Use Research Program....
