This thesis examines the relationship between the community and school in Arctic Bay in north Baffin Island. The objective is two-fold: first, to provide insights into the interaction between Inuit community members and school, and second, to describe and analyze the internal changes that school effects among community members. The central concern underlying the thesis is the ongoing process of Inuit cultural change. / This thesis expands the framework for studies in educational anthropology in two ways. First, the thesis examines the interaction between the community and the school from the perspective of the community, rather than from that of the school. Second, it applies anthropological understandings of social structure, social control and social personhood as analytical categories in examining the two cultural contexts. The thesis illustrates the fundamental contradictions in worldview between Inuit and the institution of schooling. / Observations of contemporary life illustrate that Inuit have been able to maintain the organizing principles of their kinship system in the transition from pre-settlement life to the community. Observations of socialization in school illustrate that the social norms and interrelational processes young Inuit learn in school contradict some of the organizing principles of Inuit kinship. Moreover, the responsibilities that Inuit adults are required to undertake as parents of school children impinge on their kinship obligations. The thesis concludes that although Inuit have maintained authentic, albeit modified, cultural practice in the community, the socialization of school, a culturally foreign institution, increasingly impinges on their normative values and social relations.

This thesis investigates the timing and mechanisms involved in the formation of evaporite piercement structures on Ellef Ringnes Island, Canadian Arctic Archipelago. The study includes the interpretation of industry seismic reflection and borehole data to characterize the geometry of the domes, 1D backstripping of wells to investigate the role of tectonic influences on diapirism, and analogue modelling to better understand the mechanisms that drive diapirs with dense anhydrite caps. I propose that basement structures played a significant role in the formation of evaporite domes by triggering and directing salt movement. The domes developed during the Mesozoic by passive growth driven by the differential loading of salt on adjacent fault blocks, which led to their present day asymmetric geometries. Diapir growth rates in the Mesozoic were closely linked to the rate of sedimentation, which was greatly influenced by the amount of accommodation space provided by tectonic subsidence of the basin.

Microbial activity occurs year-round in Arctic soils, including during the winter when soils are frozen. From 2004 to 2008 I monitored soil microbial and nutrient dynamics in low Arctic wet and dry sedge meadows near Churchill, Manitoba. I documented a consistent annual pattern in which soil microbial biomass (MB) and soil nutrients peak in late winter, and decrease during the early stages of spring thaw, remaining in low abundance during the summer. Based on a series of experiments, resource shortages do not appear to be the cause of the microbial decline, as has been hypothesized. Observations and theoretical considerations regarding soil physical properties indicate that this decrease is driven by the influx of liquid water at thaw that brings about a rapid change in the chemical potential of water, leading to cell lysis. I have used 15N isotope tracing to show that inorganic nitrogen is taken up very quickly at thaw by the roots of the dominant plant, Carex aquatilis. This represents a critical window of opportunity for these plants, as nitrogen remains abundant only for a short time. The described annual pattern was pronounced in wet sedge sites, but some inter-annual variation is evident, for example a post-thaw soil nitrogen pulse in 2006, and low winter MB in 2008. In the dry sedge meadow, fluctuations in MB and nutrients were dampened relative to wet sites, and the annual pattern was variable, particularly after 2006. Over four years, peak winter values of soil MB and nutrient variables declined in both wet and dry sites, and this could be related to a drying trend. This work improves our understanding of the controls on decomposition and primary productivity in a system that is experiencing climate warming and increased precipitation. Changes to hydrology, carbon and nitrogen cycling, and primary productivity will have further effects on vegetation communities and higher trophic levels, including several species of migratory birds.

This study investigates how the meaning of education has changed for the Inuvialuit in Tuktoyaktuk, NWT, Canada, over a century. This is done by situating Inuvialuit educational experiences in the context of government policies, socioeconomic and cultural changes, and Inuvialuit self-determination. The study found that the meaning of education for the Inuvialuit has been and continues to be: acquiring the means to support a family. A change has occurred from learning the Inuvialuk way in the 1930s to striving for the best of both worlds in the 1970s to the dream of becoming whatever I want in the 2000s. Unfortunately, the dreams that youth have are often cut short. Among other things, the level of engagement in formal education by youth and their families is influenced by the familys past experiences and perceptions of the education system. The study identifies family, community, school, and policy factors that increased student engagement.

This thesis studies the scattering properties of different types of imperfections in large Arctic and Antarctic ice sheets. Such irregularities include cracks, pressure ridges and both open and refrozen leads. The scattering by a transition region between sea ice and a very thick ice shelf, for example as is found in the Ross Sea in Antarctica, is also treated. Methods of solution are based on applications of Green�s theorem to the appropriate situation, which leads to either a single integral equation or a pair of coupled integral equations to be solved at the boundary between the ice and the sea water. Those equations over a finite interval are solved using numerical quadrature, while those over semi-infinite ranges are solved using the Wiener-Hopf method. Results calculated using different techniques are able to be checked against each other, giving us great confidence in their accuracy. In particular, the scattering by three ice sheets of different thicknesses is confirmed analytically by mode-matching coupled with the residue calculus technique. The scattering by the single irregularities is investigated partly for its own sake, and partly with the aim of using it to treat the scattering when large numbers of features are included in a single ice sheet. The principal objective of doing this is to observe the change in the general amounts of reflection and transmission as the background ice thickness is changed. There is enough variation in our results for us to conclude that there is definite potential for using the change in an incident wave spectrum after passing through a given ice field to estimate the background ice thickness.
