Fig. 2: Sea-ice and shelf-front conditions in the years before large-scale calving events.
From: Large-scale ice-shelf calving events follow prolonged amplifications in flexure
a–i, Sea-ice types and ice-shelf damage superimposed on ENVISAT ASAR WSM imagery from daily Advanced Microwave Scanning Radiometer for EOS (AMSR-E) ARTIST sea-ice (ASI) dataset and fast-ice extent from ref. 25 (Methods) for the Voyeykov (a–c), Wilkins RC (d–f) and Wilkins CL (g–i). The images are oriented so that the relevant shelf front points upwards. For each shelf front, the images shown were taken at similar periods before the respective calving events: in the low sea-ice year 2004 (a,d,g), the year before (b,e,h) and dates less than 2 weeks before (c,f,i). Fractures are superimposed on the ice shelves (thin black curves), with two Wilkins CL fractures along which calving occurred highlighted (thick gold and purple curves).
