Short summary
Landfast ice along the Alaskan Arctic coast is vital for winter travel, yet current remote sensing only maps its extent, not safety. Using InSAR, we distinguish landfast from pack ice and classify stability via a new metric, apparent strain. We quantitatively defined three classes: bottomfast, stabilized, and nonstabilized which correspond to the stability of the landfast ice. Apparent strain reveals an increase in stability throughout the winter months.
