20072006 Résumé:
This license has been issued for the scientific research application #837.
This study is designed to examine lakes possibly affected by the proposed Mackenzie Gas Project pipeline, and lakes that can serve as future control/reference sites. The researchers will measure the following: nutrients and metals in lake water and sediments, lake water quality (DO, pH, conductivity, etc.), and benthic i...

This licence is issued for the scientific research application # 835.
This research will examine lakes possibly affected by the proposed Mackenzie Gas Project pipeline, and lakes that can serve as future control/reference sites. Measurements of nutrients and metals in lake water and sediments, lake water quality (DO, pH, conductivity, etc.), and benthic invertebrate and plankton abundance/spec...

Résumé:
Air quality is an issue at mine sites, and diamond mining can contribute large quantities of dust to the air. This dust may contain elevated levels of heavy metals. Vehicle and generator exhausts also contribute to air pollution and greenhouse gases. To acheive the goal of sustainable development, Diavik policy focuses on the need to identify potential risks and set targets for pollution preventio...

Résumé:
Butterflies are easily studied and can provide valuable information of changes occuring in northern ecosystems - including climate changes, and habitat changes. Many areas of the NWT have few studies on insects; therefore, this inventory work can inprove the baseline information of these species.
The main investigator will travel with other NWT biologists to remote study sites and near comm...

2003 Résumé:
Caribou populations fluctuate over long time spans. However, long-term records of population cycles are scarce. The population dynamics of the Bathurst and Beverly caribou herd across the Northwest Territories will be reconstructed using two proxy indic...

2002
Résumé:
The field work is intended to provide baseline fisheries data for four lakes (Horseshoe, Toss, Fay and Logan) and to obtain post-baseline fisheries data on eight lakes (Vulture, Kodiak, Nema, Cujo, Nanuq, Counts, and Slipper) within the Ekati claimblock...

2001 Résumé:
Two individuals from each of the communities of Inuvik, Aklavik, Tsiigehtchic, Fort McPherson, and Tuktoyaktuk will be interviewed about their local knowledge of tundra swan biology. Information collected will educate the researcher about local tundra swan ecology and may help generate questions that are important to communities. Interview methods will follow those used by the Arctic Borderlands E...

Résumé:
This research will contribute to an increased understanding of ecological integrity in Nahanni National Park, provide information on the importance of glacial refugia as banks of genetic diversity and highlight the value of genetic diversity as an indicator of ecological integrity. The researcher will be transported to sampling sites within the park by Parks Canada staff (plane, helicopter). At...

1997 Résumé:
The project will focus on understanding, analyzing and evaluating the reactions of the northern boreal forest ecosystems in the Great Slave Lake region due to man made stress of mining, settlement and connecting activities. The project will try to develop some general conclusions, statements and model systems. The research team (2 persons) will come from Europe to Yellowknife by plane. The base wi...

1994 Résumé:
The researcher will collect living plants (Arctic grasses), 6 - 10 species from each collection site. In addition, several plants of each species will be pressed and dried as voucher specimens to be used to check the identification. Photographs of the plants and their habitats will be made. In Ottawa, variations in DNA among different populations and species will be analyzed to study species re...
