Productivity and mercury trends in Great Bear Lake
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2018
Summary: The objectives of this research project are to collect sediment cores from up to six sites in Great Bear Lake to investigate the temporal record of diatom and lake productivity and the deposition of mercury and other metals; to investigate spatial gradients in lake productivity as influenced by station depth, distance from shore, and river influences; and to continue to investigate mercury levels ...

Investigation of factors affecting high mercury levels in fish in lakes in the Mackenzie River Basin (2002-2003)
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2003 1998
Summary: This study is based on earlier research conducted by the Department of Fisheries and Oceans which found that fish in many lakes in the Mackenzie River Basin had high mercury concentrations. This study examines the environment in which the fish live in o...

Influence of the Slave River on Great Slave Lake
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1992
Summary: The Researchers will collect a series of sediment and water samples. These will be analyzed for plant nutrients, concentration of microscopic plant cells, bacteria, suspended solids, dissolved oxygen and organic contaminants. Microscopic animals will also be netted. They will determine the abundance and composition of the animals and conduct experiments to measure their feeding rates and fat cont...
