Extended Data Fig. 3: Time series of observed wave height and peak wave period and modelled maximum ice shelf strain, in the lead up to and during the Larsen disintegration events.
From: Antarctic ice shelf disintegration triggered by sea ice loss and ocean swell
a, b, Daily significant wave height (blue) and peak wave period (red) within the Larsen boxed region (marked L in Fig. 3 for the Larsen A Ice Shelf collapse in 1995 and the Larsen B Ice Shelf collapse in 2002, respectively. c, d, Corresponding model predictions of maximum ice shelf strain for an ice shelf of thickness 80 m, 150 m and 200 m. Pink horizontal bars indicate periods when waves were propagating towards the shelf from the sector 30°–120° E, and light blue bars indicate periods when the ice concentration was less than 40%. Approximate timings of disintegration event onsets are marked as vertical dashed lines.
