GNGTS 2019 S essione 3.2 713 Fig. 3 - Portion of an exemplary GPR profile after the processing in amplitude (a); dominant frequency (b) and sweetness complex (c). H1, H2 and H3 refers to the topographic surface, to the ice top and to the glacier bed, respectively. Coloured crosses mark the intersections between different GPR profiles. In (d) the snow cover thickness in 2015 is shown. Orange lines refer to the zones in which warm ice was detected on GPR profiles. Black dashed zones indicate no frozen materials, “nd” labels mark areas without data.
