Contaminant deposition measurements in precipitation in the NWT
Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1994 1993
Summary: There is only limited information on contaminant trends in arctic ecosystems. This long-term study is examining the amounts of contaminants present in arctic ice caps. By taking core samples from ice caps, the researchers are able to measure the levels of contaminants that have been deposited by precipitation over many years. This study will also improve our understanding of the levels of conta...


Persistent organic contaminants in the Great Slave Lake ecosystem
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1995 1994
Summary: Researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Hay River, the Slave River delta and the channel region east of the Slave River. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect small animals (invertebrates) which are eaten by fish as part of an over...


Current contaminant deposition measurements in precipitation throughout the NWT
Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1993
Summary: Contaminants are carried in the air to the arctic during the winter when large-scale wind movements bring these contaminants from industrialized locations in North America, Europe and Asia to the north. Snow can collect these compounds from the air and bring them to the ground where they can accumulate. Thus, it is important to study the amount of contaminants in snow to determine the types and ...
