John Christian, former postdoc, now prof at @uoregon.bsky.social, led this study on how ice sheets and sediment work together to make grounding zone wedges, explaining pauses in Antarctic retreat over otherwise smooth reverse-sloping beds during the last deglaciation dx.doi.org/10.1029/2025...
A 1-D model coupling ice-stream flow and sediment transport simulates the development of Grounding Zone Wedge deposits Sedimentation feedbacks may turn slowdowns in grounding-line retreat into lo...
