Fig. 1: Ice speed and speed change in the Amundsen Sea Embayment.
From: Sea level rise from West Antarctic mass loss significantly modified by large snowfall anomalies
a 2017–2021 ice speed over the Amundsen Sea Embayment derived from intensity tracking of Sentinel-1a and -1b Synthetic Aperture Radar images. b Ice speed change calculated as the difference between the mean 2021 speed from Sentinel-1 and the 2005–2008 MEaSUREs annual mosaics62, 63. Note the logarithmic colour scale used in both images. Mean ice thinning rates in m yr−1 during 2003–201966 (orange contours), the ‘FG1’ flux gate65 (magenta line), glacier drainage basins100, 101 (thin black lines), and the ice-sheet grounding line2 (thick black line), are also shown.
