Spatial and long-term trends in persistent organic contaminants and metals in lake trout and burbot in Great Slave Lake/Temporal trends and spatial variations in persistent organic pollutants and metals in sea run char from the Canadian Arctic
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2004
Summary: This study is looking at the contaminant levels in lake trout and burbot in Great Slave Lake and in arctic char after their return from feeding in the ocean. Twenty burbot and twenty lake trout will be collected from the West Basin of Great Slave Lake by...

An investigation of the factors affecting high mercury concentrations in predatory fish in the Mackenzie River Basin.
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2003 1998
Summary: It has recently been learned that predatory fish in some lakes in the Mackenzie Basin have very high concentrations of mercury. This study will try to determine why the mercury concentrations are high. The researcher will fly into Cli Lake. A boat, a depth sounder and a global positional finder will be used to find out how deep the lakes in different spots. The temperature of the water, its acidit...

Persistent organic contaminants in the Great Slave Lake ecosystem.
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1995 1994
Summary: The researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Fort Resolution and Lutsel K'e. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect invertebrates and fish samples as part of an overall study of contaminants in the lake's ecosystem....
