Dating these beautiful sediments has helped show us when Thwaites Glacier unpinned and, since it was at the same time as its neighbor, a bit about how it might have retreated. www.pnas.org/doi/full/10....
Lots of great coverage of this story (and some not so great of course). One of my favorites, as it nicely covers the science and without too much hyperbole eos.org/articles/el-...
Antarctica’s “Doomsday Glacier” started losing mass midcentury, around the same time as its neighboring glacier.
The gist of our story, led by my student Rachel Clark, is that a fringing ice shelf lost contact with the shallow banks in front of Thwaites in the 1940s. These new dates were determined using lead-210, which gives ages in the pre-satellite era.
I'm still trying to get started on this platform and avoiding the old one and happy to make this my first real post.
