We present a new technique for mapping the grounding line of Antarctic ice shelves using a combination of CryoSat-2 standard and swath elevation data. Our method is based on detecting the tidal signal in pseudo crossovers, and is tested on the Siple Coast region of West Antarctica. The mapped ground...
