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...
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...
Sea ice melting on the shore at Peregrine Point, Bathurst Inlet, Nunavut. The ice contracts into vertical candle-like shapes, a process known as candling, and melts with a tinkling bell-like sound. Photograph taken June 2001.
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,...

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...
Response of RADAR Backscatter at Multiple Frequencies and Polarizations to Changing Snow and Ice Properties on a Temperate Saline LakeDownload
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...
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...
