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

Spatiotemporal Dynamics and Controls of Vegetation Net Primary Production at Greater Bay Area Outer Ecological Barrier

Biological Diversity, Volume 2, Issue 4, Page 154-162, December 2025.
The spatiotemporal dynamics of NPP were evaluated for the ecological barrier of GBA, utilizing vegetation remote sensing, land use, and meteorological data. Results revealed that the vegetation NPP in the ecological barrier was 2.29 times that of the core area of GBA, highlighting its critical ecological function.

Assessing canopy height measurements from ICESat-2 and GEDI orbiting LiDAR across six different biomes with G-LiHT LiDAR

Environmental Research: Ecology
The height of woody plants is a defining characteristic of forest and shrubland ecosystems because height responds to climate, soil and disturbance history.

Analysis of ICESat‐2 Data Acquisition Algorithm Parameter Enhancements to Improve Worldwide Bathymetric Coverage

Earth and Space Science
A major advance in global bathymetric observation occurred in 2018 with the launch of NASA’s ICESat‐2 satellite, carrying a green‐wavelength, photon‐counting lidar, the Advanced Topographic Laser Altimeter System (ATLAS). Although bathymetric measurement

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.
