Scaled laboratory data from glacier 'terminus' during 'iceberg' capsize event compared to field observations. (A) Horizontal displacement scaled from force (black line) compared to downflow GPS data (blue). (B) Vertical displacement scaled from pressure (black line) compared to vertical GPS data (red). Errors in laboratory data are standard deviation from repeated capsize events. Photos show stage of capsize at times marked by dashed lines and (solid gray line) tc. Aspect ratio of model iceberg is 0.22. Graphic: Murray, et al., 2015
