From: Influence of the grounding zone on the internal structure of ice shelves
Plots illustrate grounding zone depth and age profile at the borehole sites for A JP-21, and B SI-47. Boreholes are coloured by unit (following Fig. 3), with the grounding zone estimated from the borehole data to be at the base of Unit 2. The median model estimate of the grounding zone depth is shown by the red line, with the range between the maximum and minimum estimates (see Methods) shown shaded in light red. Time in years since ice crossed the grounding zone is shown by the secondary purple axis and line. Upper and lower ice surfaces are taken from MEaSUREs Bedmachine Antarctica V.335. Source data are provided in the source data file.
