The Arctic environment is changing rapidly. The purposes of this study were: (1) to predict the possible changes of diet composition and the subsequent changes in nutrient intakes as a result of environmental changes; (2) to explore the possibility of minimizing the contaminant exposure while maintaining the energy and nutrient intakes using liner modeling. It was found that a decrease of 10% or 50% of caribou or ringed seal will result in decreases for many key nutrients such as protein, zinc, and iron. It is theoretically feasible to minimize each contaminant intake while maintaining energy and nutrients at the levels of the CINE dietary survey in 2000 for Inuit in the Inuvialuit, Kitikmeot, and Kivalliq regions. However, it is theoretically infeasible for Inuit in the Labrador and Baffin regions under other hypothetical conditions. The modeling results would be useful for Inuit to make informed food choice decisions.

This thesis presents an investigation of the variations in the magnetic field obtained in the Mackenzie Bay/Beaufort Sea area of the Canadian Arctic. It was found that the variations obtained at sea were strikingly correlated with those recorded at Point Atkinson, a fixed station on land, 150 miles from the survey area. In addition, it was found that the higher frequencies present in the marine records were severely attenuated with respect to the corresponding frequencies in the Point Atkinson recordings. It was concluded that the Mackenzie Bay/Beaufort Sea area is geomagnetically anomalous and that this situation is probably caused by higher electrical conductivity material underlying, the Mackenzie Bay/Beaufort Sea area, abutting lower conductivity material of the North American craton underlying Point Atkinson. This conclusion has important implications relating to the tectonic history of the Canadian Arctic. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

The conservation of wildlife species plays a profound part in development issues in northern areas. In recent years, northern wildlife management has become a complicated process of cross-cultural communication. This thesis begins with an outline of the relations between First Nations and Euro-Americans in the context of the dynamics between wildlife scientists and aboriginal subsistence-based communities. The current economic, social and political characteristics of subsistence systems are discussed. The emergence of co-management systems is described in a review of wildlife management institutions existing in northern Canada and Alaska. An analysis of the activities of the Beverly-Qamanirjuaq Caribou Management Board (B-Q CMB) and the relative participation of traditional users and government wildlife scientists forms the core of an exploration of the nature of wildlife co-management. In order to understand some of the perspectives of local caribou-using communities within the co-management framework, interviews were held with members of the Inuit community of Arviat, Nunavut and the Sayisi-Dene community of Tadoule Lake, Manitoba. Finally, the general role of co-management institutions in securing the viability of communal property regimes is discussed with specific reference to the case of the B-Q CMB.
