This data set provides a comprehensive map for the Antarctic Ice Sheet of the short-term zone of migration of the ice grounding line (i.e., the transition boundary between grounded ice and ice floating in the ocean waters) for the given period, due to changes in oceanic tide. This variation is represented by polylines that indicate the upstream and downstream bounds in the grounding line variation for a given year. The data are derived using an automated machine learning algorithm to delineate thousands of grounding lines in interferometric synthetic aperture radar (InSAR) data acquired by Sentinel-1 A/B, supplemented by data from COSMO SkyMed, RADARSAT-2, and European Remote Sensing (ERS) satellites.
