Reconnaissance Study of Smoking Hills
chercheur principal: Dunfield, Peter F
Année(s) de permis: 2013
Résumé: The objective of this work is to conduct a one day reconnaissance study of the Smoking Hills area. Mineral, rock, water and soil samples will be collected. Geochemical properties and microbial communities will be analysed in the laboratory in order to characterize any potential features unique to this site that would warrant future, more detailed research. The site will be accessed by helicopt...

The presence and persistence of arsenic trioxide in soils around Giant Mine, NWT
chercheur principal: Bromstad, Mackenzie J
Année(s) de permis: 2010
Résumé: The objective of this project is to understand why arsenic trioxide (As3+) is still present in soils around Giant Mine, how long it will remain there, and if the set of circumstances leading to persistent As3+-rich soil may apply to any other places previously assumed to be As3+-free. In terms of current mine remediation, future human contact with the site, and ecosystem health, it needs to be und...

Paleoenvironment of the Truelove Lowland Area, Devon Island, N.W.T.
chercheur principal: King, Roger H.
Année(s) de permis: 1994 1992 1991 1990 1988
Résumé: The Researcher and his team will study the age, chemistry and fossil organisms preserved in the lake sediments of the Truelove Lowland and use this information to reconstruct past environmental changes. The object is to reconstruct the environmental changes that have taken place in these Polar Oases during the last 10,000 years....
