Changes in area, flow speed and structure of southwest Antarctic Peninsula ice shelves in the 21st century
Since the mid-20th century, ice shelves around the Antarctic Peninsula have Waist declined in extent and thickness, and some have shown signs of structural instability.Here, using satellite imagery from 1999/2000 to 2019/20 (Landsat 7 and 8, Sentinel-2 and ASTER), we measure areal changes, calculate surface flow speeds, and quantify structural chan
