Modelling the Impact of Climate Change on the Polar Bear Population in Western Hudson Bay
The aim of this thesis is to model the impact of climate change on polar bear populations. The first model is a discrete matrix model with time-dependent parameters, which are influenced by temperature increases. Sensitivity analysis is done on the model. Numerical simulations predict there exist …

Mesoscale Wind and Temperature Changes over Peatlands of the Hudson Bay Lowlands: impacts on the Surface Energy Balance and Net CO2 Exchange
… to global warming and moisture changes. The Hudson Bay Lowlands (HBL) region of Canada is the second largest peat-accumulating complex in the world that is strongly influenced by the cold air masses originating off the Hudson Bay. Recent warming has caused observed changes in the sea ice …

Characterizing Provenance of the Late Wisconsinan Rainy Lobe Using Fine-Fraction Geochemistry and Detrital Zircon Geochronology
… sediments reflect long-distance transport from Hudson Bay, and later phases reflect increased proportions of felsic shield lithologies and Duluth Complex rocks with a corresponding decrease in carbonate. These two models of Rainy lobe till sedimentology are evaluated using mixing models, till …

Using Minimally Invasive Sampling Methods to Evaluate Polar Bear (Ursus maritimus) Visitation in Response to Environmental and Anthropogenic Stimuli
… bear visitation to infrastructure in western Hudson Bay, and how these factors drive the growing risk for human-polar bear conflict. More specifically, examining the links between sea ice breakup and freeze-up dates, the length of the onshore season, polar bear body condition, human presence, …

The Rankin Inlet Ceramics Project : a study in development and influence
… Rankin Inlet, a community on the west coast of Hudson Bay in the Northwest Territories. This community was established by the mining company and attracted a large Inuit population with its promise of wage employment. When this employment ceased, the Canadian government initiated an arts and …

Halogen Oxide Studies in the Boundary Layer by Multi Axis Differential Optical Absorption Spectroscopy and Active Longpath-DOAS
… within this work. The measurements at the Hudson Bay represent the southernmost and first direct observations of Arctic surface ozone losses due to BrO and allowed for the first time to study the day and nighttime chemistry of BrO at high time resolution. Molecular bromine was inferred to …

Air-Sea CO2 Exchange and Carbon Dynamics in Foxe Basin: Findings from a 2023 Oceanographic Survey
… deep waters. Foxe Basin, an inland sea north of Hudson Bay between Baffin Island and Melville Peninsula, is an ideal location to study this process as it is one of the few known places in Canada where sea-ice-driven deep water formation occurs consistently. A synoptic survey took place in Foxe …

The Effects Of Ecotourism On Polar Bear Behavior
… they gain access to seals and mates. In western Hudson Bay, the sea ice melts for three to four months in the summer, and polar bears there are forced onto land. These bears live on their fat reserves for the duration of the iceless period, until temperatures get colder in the fall and freeze up …
