Fig. 2: Example of GPR data and of its analyses and interpretation.

Portion of interpreted GPR profile SE-NW crossing the BCG. a Processed reflection amplitude; b interpreted reflection amplitude; c interpreted cosine of instantaneous phase attribute; d interpreted dominant frequency attribute. Location of Borehole B1 is marked by the yellow arrow and the white bar. Light blue, red and dark blue dashed lines mark the base of firn, the glacial unconformity and the till, respectively. All the other dashed lines depict the most apparent layers within the glacier. Vertical exaggeration 1.5x.
