A Framework for Characterizing 3-D Structures of Crevasses and Rifts Across Antarctic Ice Shelves (opens in new tab)

Brittle failure by crevasses and rift formation is the most directly observable expression of stress state in glacier ice. Both satellite imagery and satellite altimetry are effective tools for characterizing them. However, the ice shelf surface exhibits nonfracture-related features that can appear similar to crevasses and rifts in images or elevation profiles, making it challenging to distinguish them using a single observational perspective. Here, we combine satellite altimetry and satellit...
