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...


Devon Canada Corporation - Fish, Plankton & Benthic Communities Study for the Proposed Beaufort Sea Offshore Drilling Program within the Inuvialuit Settlement Region
Principal Investigator: Evans, Kevin
Licensed Year(s): 2002
Summary: Research program on the fish, plankton and benthic communities. Potential effects of the drilling program on benthos include effects of chemical contaminants from drilling fluid wastes on the benthic community and hence the food web, and loss/change in b...


Environmental Study of the Aquatic Resources of the Thonokeid Lake Area
Principal Investigator: Couture, Richard
Licensed Year(s): 1994 1994 1993
Summary: Rescan Environmental Services Ltd. will continue their study on the types of fish and other aquatic organisms found in the Thonokeid Lake area. Data on species type as well as their age, abundance and habitat will be collected. In addition, muscle and liver tissue of fish will be collected in order to assess for the presence of heavy metal contaminants. This study will be summarized in an envir...


Environmental study of the aquatic resources of the Lac de Gras area
Principal Investigator: Couture, Richard
Licensed Year(s): 1993
Summary: The researchers of Rescan have been contracted by B.H.P. Minerals Canada Ltd. to conduct an assessment of the types of fish and other aquatic organisms that are found in the Lac de Gras area. Tissue samples will be collected in order to assess heavy metal contaminants in fish. An environmental report will be submitted to the Territorial Government on the results of this study....

Latitudinal patterns of organochlorine contamination in zooplankton
Principal Investigator: Koenig, Brenda
Licensed Year(s): 1993
Summary: Organochlorine contaminants can be carried to the arctic in the atmosphere. I will be measuring the amount of these contaminants in zooplankton to determine the effects and range of organochlorines in the arctic ecosystem. The information that I collect will be useful in determining what types of organochlorines are most common in zooplankton as well as providing a means to estimate the levels o...


Productivity of Marine Mammal Food Chains in the Northwest Passage
Principal Investigator: Welch, Harold
Licensed Year(s): 1993 1992 1991 1990 1988 1987
Summary: The researcher and his team will quantify benthic invertebrates such as snails and clams, monitor phytoplankton, nutrients, and zooplankton, sample Char Lake fauna and flora for stable isotope and heavy metal analysis, and study schools of arctic cod and associated predators....
