Seasonal and Multi-annual Dynamic Monitoring of Belcher Glacier, Nunavut Canada using SAR Imagery
Belcher Glacier is one of the largest tidewater outlets glaciers of Devon Ice Cap, and a key area of ice discharge to the ocean within the Canadian Arctic as a whole. The glacier covers an area of 1180 km2, and ranges in elevation from sea level to around 1920 m. Previous work has mapped the motion...
