Recent paleolimnological research in the eastern Canadian high Arctic on the ecological impact of the Thule c.1000-1500 AD has documented the influence of prehistoric anthropogenic activities. Six lake and pond sites (three pairs) on the south-western coast of Baffin Island, Nunavut, were used to compare impacted and non-impacted sites in the southern-most region of Thule occupation, as well as to compare Thule occupation sites with sites occupied by another early Arctic population group, the Dorset. Tanfield 1 and Tanfield 2 (impacted and control, respectively) are adjacent to several multiple-occupation Dorset sites on Cape Tanfield; Juet 1 and 2 (impacted and control, respectively) are adjacent to a short-term occupation Dorset site on Juet Island; McKellar 1 is adjacent to a multiple-occupation Thule site near McKellar Bay. A nearby site (McKellar 2) was also studied, but it was clearly an anomalous, eutrophic site, rather than a control for McKellar 1. Diatom assemblages and sedimentary 15N profiles were analyzed in sediment cores from all study sites. Selected paired sediment intervals were AMS radiocarbon dated using both humic acids and terrestrial macrofossils in an attempt to establish basal dates for each core. Significant differences between several of the paired AMS radiocarbon dates serve as a cautionary note for dating Arctic sediments using either humic acids or terrestrial macrofossils. Paleolimnological analyses revealed that at both multiple-occupation sites (Tanfield 1 and McKellar 1), the activities of the Dorset and the Thule influenced lake ecology, while at the short-term occupation site (Juet 1), the Dorset occupation was not sufficiently large to have a discernible impact. McKellar 1 showed a greater impact compared to Tanfield 1, consistent with the intense marine mammal hunting by Thule at the former, compared to the moderate marine mammal hunting by Dorset at Tanfield 1. The origin of marine-derived nutrients at McKellar 2 could not be ascertained with certainty. The influence of early Arctic population groups remains obvious in present-day nutrient- and production-related water chemistry variables. This research points to the value of collaborations between paleolimnologists and archaeologists and may provide insight into the future implications of current anthropogenic activities in the Arctic. / Thesis (Master, Biology) -- Queen's University, 2011-10-04 15:52:18.29

This thesis presents an exploratory approach using detailed zooarchaeological analysis to evaluate the nature of ringed seal ( Phoca hispida) remains from three seasonally different Thule sites in the Hazard Inlet area of Somerset Island, Nunavut. Most Thule research focuses on winter occupation and presents Thule as a whaling society. Little attention has been given on the nature of sealing during Thule occupation and research on seasonal differences of seal remains from Thule sites remains scarce. This thesis is thus one of the first to focus on ringed seal remains from seasonally different Thule sites through an analysis of over 30,000 bone specimens. The goal of this thesis is to determine if the seal assemblages are a product of differential butchering and transport, taphonomic processes, or if external factors are also playing a role in shaping the faunal record. The analysis considers variability within each site as well as between the sites. Overall, a moderate to strong correlation was found between bone density and the seal bone elements identified while a negative correlation existed with the elements and FUI (food utility indices). This led to the conclusion that taphonomy was the leading agent shaping the seal remains at Hazard Inlet. However, enough variation existed within each site to consider the role of outside factors, such as the presence of dogs, food preferences, food storage and season of occupation in shaping the seal remains at Hazard Inlet.

Dental annuli analyses were performed on 170 ringed seal (Phoca hispida) canines recovered from five Thule semisubterranean houses located at site PaJs-13 at Hazard Inlet, Somerset Island in the central Canadian Arctic. Season of death results indicate greater seal hunting during the spring. Age at death results were used to produce mortality profiles which, when compared with idealized patterns, revealed a prime-dominated pattern indicating the presence of some selective factor in the subsistence strategy. Based on ethnographical studies of traditional seal hunting techniques, conscious selection was eliminated as a factor. Biological studies of ringed seal demonstrate that during the spring, older, sexually mature seals, occupy breeding areas in stable fast ice formations located close to the coast in complex coastal areas. Younger immature seals, on the other hand, occupy areas of unstable pack ice formations either further from the shore in complex coastal areas, or along simple coastlines. The archaeological mortality patterns do not clearly resemble either complex or simple coast modern populations, although a trend toward simple coasts was observed. This observation is consistent with the site location, which allows greater access to pack ice formations. The appearance of selective biological factors affecting random human subsistence strategies indicates that caution must be utilized when interpreting mortality patterns.

The goal of this thesis is to re-evaluate the origins of the Caribou Inuit. The thesis presents theories that have been proposed by Birket-Smith (1929), Burch (1978), and Clark (1978). Each theory represents a diverse perspective regarding Caribou Inuit origins that include, respectively, a proto-Eskimo origin, an immigration origin, and cultural change resulting from European contact. / The alternative theory being proposed in this thesis is that change in environmental conditions that resulted from the Little Ice Age caused the most favoured food resource, the ringed seal, to decline significantly in abundance because the necessary ice conditions that are required for these seals to inhabit a particular area no longer existed. The implications that are discussed and tested as a result of a decline in marine resources are there would have been a shift in focal resources, a corresponding change in regional territories, and a change in subsistence-settlement systems.

This master thesis report describes the process of designing, developing and building an accessory for a stroller that protects the kid from rain and sun. The project is a collaboration with Thule Sweden AB, in Hillerstorp.The work starts with developing a new concept idea for Thule’s category “Active with kids”, in the line of strollers, and with a focus on the Southern Europe market, more concretely Spain. The design proposal fits and expresses Thule’s vision and brand language.The project started with gaining knowledge about the market, investigating the user needs with surveys to find out the design goals. An iterative process of ideation, brainstorming and building mock-ups ended with a final concept that was going to be further developed. A full-scale model was built to test the idea from the functional and aesthetic perspective. The materials used were mainly fabrics, foam, zippers, thread and a lot of sewing.The result is a new stroller canopy for different weather conditions. It is well equipped to improve parents experience when going out for a ride with their child.It has to be mentioned that this master thesis research section was conducted in pairs, between Berta Cester and Nerea Cuello, and the rest of the phases was an individual work. As a result, two different products were produced for the same category, the stroller market.
