Projections of polar bear (Ursus maritimus) sea ice habitat distribution in the polar basin during the 21st century were developed to understand the consequences of anticipated sea ice reductions on polar bear populations. We used location data from satellite-collared polar bears and...

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...

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...

Simulating sea ice drift and deformation in the Arctic Ocean is still a challenge because of the multiscale interaction of sea ice floes that compose the Arctic Sea ice cover. The Sea Ice Rheology Experiment (SIREx) is a model intercomparison project of the Forum of Arctic Modeling and...

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...

In this analysis, we examine relative contributions from climate change and river discharge regulation to changes in marine conditions in the Hudson Bay Complex using a subset of five atmospheric forcing scenarios from the Coupled Model Intercomparison Project Phase 5 (CMIP5), river discharge...

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...

Richardson, E., Stirling, I., Thiemann, G.W., Derocher, A.E.

In April and May 2003 through 2006, unusually rough and rafted sea ice extended for several tens of kilometres offshore in the southeastern Beaufort Sea from about Atkinson Point to the Alaska border. Hunting success of polar bears (Ursus maritimus) seeking seals was low despite extensive...

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...
