The internal stratigraphic structure of ice shelves forms by the interplay of ice dynamics, snow accumulation and basal melt. To infer accumulation and basal melt rates, we acquired a ground-penetrating radar profile (50 MHz; pulseEKKO (R) from Sensors & Software Inc.) along the central flowline...
