My research focuses on the cryosphere (the portion of the Earth influenced by ice and snow) as well as ice-dependent ecosystems. I studied polar glacial ecosystems as a graduate student in Antarctica and the High Arctic. Then as a postdoctoral fellow, I used radar and optical remote sensing to study lake ice cover, ice shelves and ice islands. My current interests include developing remote sensing techniques for change detection of ‘extreme’ ice features along the northern coast of Canada. I am examining the relationship between changes in the cryosphere and climate and place my geophysical research in a broad ecological context.
- Arctic coastal ‘extreme’ ice features (ice shelves, multiyear landfast sea ice, ice-dammed lakes)
- Arctic ice islands
- Indicators and impacts of climate change in the cryosphere
