Extended Data Fig. 2: Examples of transects used to calculate sea- ice lengths and model outputs.
From: Large-scale ice-shelf calving events follow prolonged amplifications in flexure
(a,c) Arbitrary selections of 40 transects (white lines; out of ≈ 9000) for the Wilkins RC on (a) 27 February 2007 and (c) 19 June 2008 (≈ one week before its large- scale calving event), with the underlying satellite image from ENVISAT ASAR WSM imagery, including lines for the outer boundaries of the pack- ice, annual fast-ice and perennial fast-ice barriers, and significant wave heights from the CAWCR hindcast52. (b,d) Model outputs for transects highlighted in the corresponding left-hand panels (thick orange lines), for the wave height in the sea-ice intervals showing attenuation over distance and drops at the fast-ice edges, and the resulting flexural stress on the Wilkins RC. The incoming swell have wave height and period (b) H ≡ 2A = 9.9 m and T = 14 s, and (d) H = 8.6 m and T = 11.6 s, corresponding to the left- hand panels.
