Extended Data Fig. 3: Recent changes in EAP ice-surface flow.
From: Antarctic ice-shelf advance driven by anomalous atmospheric and sea-ice circulation
a, Landsat 8-derived velocity change between 2016 and 2018 over the Antarctic Peninsula region. Black lines delineate the ice drainage basins detailed in a recent study84. The 2018 ice front position is also shown. To minimise erroneous data coverage over ice divides and other regions of complex topography, data are masked (dark grey) where Verror exceeded 30 m yr-1 in either 2016 or 2018 (or both). Black box indicates the detail shown in c and d. b, Landsat 8-derived Verror. In c and d, HGE denotes Hektoria, Green and Evans; C, Crane; F, Flask and L, Leppard glaciers. Note the continued dynamic acceleration of Flask and Leppard glaciers following the disintegration of Larsen B Ice Shelf in 2002, and the lack of any similar grounded ice-flow acceleration upstream of Larsen C Ice Shelf following the calving of iceberg A-68 (Fig. 1).
