From ice shelves to icebergs: Classification of calving fronts, iceberg monitoring and drift simulation

Antarctica is surrounded by ice shelves and glaciers of different sizes. Satellite imagery shows different feature patterns (e.g. crevasses, rifts) at their surfaces, which control the shape and the size of icebergs that calve from their seaward edges. An edge detection method was used to map and cl...
