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....


Basin-Wide Fall Burbot Collection
Principal Investigator: Bong, Tom D.
Licensed Year(s): 1994
Summary: The researcher will collect fish for analyses of contaminant body burdens. The sample size for each species will be 10-15 of each sex at each sampling site. Fish will be collected using set lines set in the evening and fished overnight. Blood samples will be taken from live fish and then tissues will be sampled and sent to labs for analyses. Gut contents will be examined and the fish will be aged....


Banks Island Fish Populations/Char Genetic Variation Project
Principal Investigator: Babaluk, John
Licensed Year(s): 1994 1993
Summary: This is a continuing project to survey fish populations of lakes and rivers. In the past population studies have been conducted in the Fish and Raddi lakes, the Sachs River and the Benard River. This year Middle and Kuptan lakes will be surveyed and if there is time Capron and Swan lakes may also be surveyed. The project will also continue studies on genetic and morphological variation in Arcti...


Qualitative Assessment of Local Terrestrial Plants and Identification of Potential Commercial Uses.
Principal Investigator: Copland, Elizabeth
Licensed Year(s): 1994
Summary: Samples of plants will be collected by local residents and identified, some of which may have to be sent away for identification. Elders will be used as resource people to determine possible traditional uses of the plants. The researcher will also experiment with the various land plants to develop appropriate products. If a suitable product can be developed then each plant will be analyzed for ...


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...


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...


Lichens as indicators of trace-element air pollution in the environment and environmental controls on plant species richness and composition along an arctic river
Principal Investigator: Gould, William
Licensed Year(s): 1994 1993 1992 1991 1990
Summary: Project 1: Small samples of lichens will be collected from approximately 20 sites located along the Hood River and analyzed for contaminants. Lichens are good indicators of the types of air-borne contaminants that have been carried north to the arctic since they absorb their nutrients from the air. Project 2: The researcher will examine plant communities along the Hood River in order to study th...


Investigation of the nervous and immune systems in the beluga
Principal Investigator: Romano, Tracy
Licensed Year(s): 1993
Summary: This research will examine the nervous (i.e., brain) and immune systems of beluga by collecting these tissues from harvested animals for laboratory analyses. This study will help to determine how contaminants affect the health of belugas. In addition, the data collected may lead to a better understanding of why whales strand themselves on the shoreline as it has been suggested that beached whale...


Foxe Basin Walrus Hunt Monitoring Program
Principal Investigator: Stephenson, Tasha
Licensed Year(s): 1993 1992 1991
Summary: This project will involve the collection of data on the harvest of walrus in the Foxe Basin area. Measurements will be taken on the walrus harvested and tissue samples will be collected for the purpose of assessing contaminant levels in tissues. Hunters from Igloolik and Hall Beach will be trained in sampling techniques and the local Hunters' and Trappers' Associations will be contracted to carr...


DeSalis River fishery monitoring, 1993
Principal Investigator: Stabler, Matt
Licensed Year(s): 1993
Summary: Anadromous arctic charr, currently viewed of as the eastern form, are known to spawn and overwinter in the DeSalis River system. Residents of Sachs Harbour have expressed an interest in harvesting arctic charr from this system for consumption and commercial purposes. Two resident monitors will sample the subsistence catch of this stock in order to estimate stock size and age. Whole fish will be ...
