a, Change in grounding line location (GLL) between 1994-6, 2016-7 and 2019 as determined from satellite radar-based techniques (Methods). Following Fig. 1, symbols denoting recent (2016/7-2019) GLL change proximal to Larsen C Ice Shelf (LC) are also shown, as well as the position of the 2019 ice front (maroon) and ice surface velocity contours83 (100 m yr-1 increments) over grounded ice. b-j, spatial extent of GLL change across the regions labelled in a, superimposed over recent ice surface velocity magnitudes83. Ca denotes Casey Glacier; Lu, Lurabee; An, Anthony; Cr, Croom; Cl, Clifford; Ma, Matheson; Ya, Yates; Da, Dana; Mu, Murrish; So, Soto; Ha, Haley; Cli, Cline; Ra, Rankin; Gr, Gruening; Ru, Runcorn; Mr, Maury; Fe, Fenton; Mo, Mosby; MH, Meinardus-Haines and Wa, Waverly glaciers. K denotes the unnamed glacier draining to Keller Inlet. All other abbreviations are the same as in Fig. 1.
