Assessing stress in western Hudson Bay polar bears using hair cortisol concentration as a biomarker
DownloadFall 2015
The development of novel biomarkers to help assess whether polar bear (Ursus maritimus) health is impacted by long-term physiological stress associated with climate change represents an emerging area of research. With progressively greater reductions in sea ice cover and a corresponding decrease...

Spring 2016
The Arctic Ocean sea ice is shifting from a system dominated by thick perennial ice (multiyear ice –MYI) to one dominated by thinner, seasonal ice (first year ice – FYI). The effects of this shift on the bacterial constituents of the Arctic sea ice have been grossly under studied, although it is...

Polar Bear (Ursus maritimus) Habitat, Space Use,and Movements in a Seasonal Sea Ice Ecoregion
DownloadFall 2015
Polar bears (Ursus maritimus) are sea ice habitat specialists and climate change has affected sea ice throughout this species’ circumpolar range. The annual phenological cycle of sea ice growth and decay is a strong influence on polar bear distribution and ecology. Study of the habitat selection,...

Response of RADAR Backscatter at Multiple Frequencies and Polarizations to Changing Snow and Ice Properties on a Temperate Saline Lake
DownloadSpring 2012
Currently there is a lack of knowledge regarding the distribution of the mass of snow, or snow water equivalence, over land and ice. The proposed CoReH2O satellite mission aims to address this by launching the first coincident dual-frequency, dual-polarized Ku- and X- band Synthetic Aperture...

Fall 2010
The sea ice fields produced by the NEMO sea ice/ocean coupled model’s prognostic simulation drift from reality in the Labrador sea. Thus four additional data assimilation experiments were conducted in order to obtain satisfactory sea ice fields. In the first two experiments the model’s sea ice...

Fall 2012
This study presents large scale sea ice melt estimates derived by comparing AEM ice thickness surveys conducted in the Lincoln Sea (spring) and Nares Strait (summer) in 2009. The exact same ice was not surveyed during both campaigns but comparison of ice thickness was conducted between regions...

Fall 2013
This thesis presents the numerical simulations related to freshwater processes within the Canadian Arctic Archipelago (CAA) using a coupled ocean and sea ice pan-Arctic model based on NEMO v3.1. In this study, two major routes for the export of Pacific water to the North Atlantic, via either Fram...

Walking in Their Footsteps: New Approaches to Identify Behavioural Processes and Define Home Ranges Using Animal Movement Data
DownloadFall 2014
Animal movement and space-use patterns influence the distribution and abundance of species, predator-prey interactions, and many other ecological processes. Different approaches are used to study individual's space-use strategies and each approach suffers from unique challenges. The mechanistic...
