ICESat-2’s Laser Fires 2 Trillionth Shot, Spots Clouds – ICESat-2

Last week, NASA's ICESat-2 laser instrument, launched in 2018, fired a milestone 2 trillionth shot! blogs.nasa.gov/icesat2/2025...

Increased crevassing across accelerating Greenland Ice Sheet margins - Nature Geoscience Greenland-wide observations of crevasse volume and distribution suggest substantial increases in crevassing between 2016 and 2021 at marine-terminating sectors with accelerating ice flow.

Our new paper is out in Nature Geoscience! In an ice-sheet-wide 3-D inventory of crevasses in 2016 and 2021, we find that crevasses are growing in response to ice acceleration on short timescales. @durham-university.bsky.social @byrdpolar.bsky.social @leverhulme.bsky.social
