Mélange‐Driven Coupling Between the Central Pine Island Ice Shelf and the Piglet Glacier Reverses Recent Acceleration Trends

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract By analyzing velocity changes of the Pine Island Ice Shelf (PIIS) from October 2014 to August 2025 using Sentinel‐1A/B imagery, we find that the PIIS flow changed markedly over this period. A distinct slowdown occurred at the central PIIS from 14 March 2022 to 20 January 2023, during which velocities decreased from 13.15 ± 0.04 to 12.71 ± 0.17

Quantifying Volumetric Scattering Bias in ICESat‐2 and Operation IceBridge Altimetry Over Greenland Firn and Aged Snow

Earth and Space Science
The Ice, Cloud, and Land Elevation Satellite‐2 (ICESat‐2) mission has collected surface elevation measurements for over 5 years. ICESat‐2 carries an instrument that emits laser light at 532 nm, and ice and snow absorb weakly at this wavelength.
