Abstract.

This paper presents a study, by means of of Synthetic Aperture Radar (SAR) images, of the fracture of the Nansen Ice Shelf, from its first appearance in SAR images to the final collapse on 7 April 2016. Both Sentinel-1 and Cosmo-SkyMed images have been used. First, the images were remapped onto an equidistant cylindrical projection; from these a subset, or imagette, only covering the fracture was extracted. A segmentation scheme was then applied to the sequence of imagettes in order to produce a sequence of binary imagettes with only the fracture area enhanced; from these, the computation of fracture area became a trivial task.
