712 GNGTS 2019 S essione 3.2 Fig. 2 - Ice thickness maps in 2004 (a) and 2014 (b); 2004-2014 ice thickness difference (c). Black and red lines mark the 2004 and 2015 GPR profiles, respectively; yellow lines highlight the glacier segmentation; black dashed zones indicate no frozen materials in 2015; “nd” labels mark areas without data, while “X” refers to zones with unrealistic thicknesses due to poor data coverage.
