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

Variational inference of ice shelf rheology with physics-informed machine learning Open
Floating ice shelves that fringe the coast of Antarctica resist the flow of grounded ice into the ocean. One of the key factors governing the amount of flow resistance an ice shelf provides is the rigidity (related to viscosity) of the ice…
