Cover Story (view full-size image): The figure shows an elevation model of the Filchner–Ronne Ice Shelf in Antarctica derived from CryoSat-2 swath altimetry data acquired in 2018. The color coding indicates the surface elevation scaled from 0 to 200 m. The calving front location (CFL) marks the seaward limit of the shelf and is indicated by a series of lines illustrating the gradual advance of the ice shelf in the period 2011–2018 with a 6-month sampling. Mapping the time variable CFL of Antarctic ice shelves is important for estimating the freshwater budget or as a precursor of dynamic instability. Wuite et al. have developed a novel approach for deriving regular and consistent CFLs based on edge detection and vectorization of the sharp ice edge in gridded elevation data, representing a valuable new application for the CryoSat-2 mission that has not been previously exploited.View this paper.
