Summary: For several years, studies have been conducted to find out if contaminant levels are changing in lake trout and burbot in Great Slave Lake. The researchers have been seeing some changes with mercury levels increasing and HCH levels declining in these fish. However, there have been other changes in the fish, especially lake trout which appear to contain less fat and to be feeding closer to shore th...

Summary: The crew will fly from Yellowknife to the Tundra Ecosystem Research Station camp on Daring Lake from BHP (Ekati Mine) by helicopter. The research team itinerary consists of: (1) setting up the camp; (2) sampling all of the major streams flowing into Daring Lake for chemistry and instantaneous flow; (3) walking through several basins to decide on an intensive sampling site; and (4) installing dri...

Summary: The extensive wetland complex in Wood Buffalo National Park (WBNP) is composed of a mosaic of shallow ponds that are unique in Canada. They are also the nesting grounds of the last migratory population of Whooping Cranes. Water, organic matter, aquatic plants and small aquatic life forms will be sampled from ponds just outside the nesting area and 0.5 km from the highway. The research team will ...

Principal Investigator: Couture, Richard
Licensed Year(s): 1994 1994 1993
Summary: The researchers will continue their study on fish and other aquatic organisms found in lakes and streams of the Thonokeid Lake area. Muscle and liver tissues of fish will be taken in order to assess levels of heavy metals. In addition, water chemistry data will be collected....

Principal Investigator: Beyens, L.
Licensed Year(s): 1992 1987
Summary: In the vicinity of Cambridge Bay the researcher hopes to gain more insight in the biogeography and ecology of unicellulars, i.e. diatoms and testate amoebae. A small collection of samples of terrestrial and aquatic material will be undertaken....

Principal Investigator: Nicholson, Barbara
Licensed Year(s): 1992
Summary: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...

Principal Investigator: Dickman, Mike
Licensed Year(s): 1988
Summary: To investigate photosynthetic sulphur bacteria present in two meromictic lakes; to determine chemical and biological characteristics of two meromictic lakes (water does not turn over and bottom layer is without oxygen)...

Principal Investigator: Andrews, John T.
Licensed Year(s): 1988 1987
Summary: To obtain a series of lake cores from outer Iqaluit, Baffin Island, NWT, from ca. 100 m. above sea level down to sea level; examine the cores for changes in the diatom floras which respond to shifts in the pH of the water and salinity, as well as samples for radiocarbon dating and pollen analysis....
