摘要: Seasonal landfast sea ice stretches along most Arctic coastlines and serves as a platform for community travel subsistence, industry operations, habitat marine mammals. Landfast can feature smooth areas of m-scale roughness in the form pressure ridges. Such ridges significantly hamper trafficability, but if grounded also serve to stabilize shoreward ice. We investigate use synthetic aperture radar interferometry (InSAR) assess formation movement near Utqiagvik, Alaska. The evaluation is based on InSAR-derived surface elevation change between two TanDEM-X bistatic image pairs acquired during January 2012. compare results with backscatter intensity, coastal data, SAR-derived drift evaluate utility this approach its relevance ridge properties, well evolution, dynamics, stability. © 2020 by authors.
