This dataset contains the location of the grounding line along George VI Ice Shelf (West Antarctic Peninsula), Wilkins Ice Shelf and Bach Ice Shelf (Alexander Island), as determined from a compilation of datasets, including double-differential interferometric synthetic aperture radar (DInSAR) from Sentinel-1 imagery acquired May-October 2020, Sentinel-1 grounding-line information from 2018 (Mohajerani et al., 2021) and the MEaSUREs 1994-1996 grounding line dataset (Rignot et al., 2016). The dataset is provided in ESRI Shapefile (.shp) format.This research was undertaken while KB was in receipt of a United Kingdom Natural Environment Research Council PhD studentship awarded through the University of Cambridge C-CLEAR Doctoral Training Partnership (grant number: NE/S007164/1). This work was also produced with financial assistance (to FDWC) of the Prince Albert II of Monaco Foundation, and (to ICW) from the United Kingdom Natural Environment Research Council awarded to the University of Cambridge (grant number: NE/T006234/1).
