Quantifying of the ten-year variation in surface velocity of the Svalbard Archipelago glaciers using SAR data

Dynamic climate changes are especially noticeable in polar regions, where glaciers are retreating landward at an increased rate. This study emphasizes the application of the feature tracking method for analyzing the ice flow velocity across the entire Svalbard archipelago from 2015 to 2024. We conducted our analysis using the Geogrid and autoRIFT platforms, complemented by Sentinel-1 imagery. To validate our ice velocity products, we employed the Glacier Feature Tracking (GLAFT) aproach. Our analysis culminated in the development of an extensive glacier repository for the archipelago, which includes velocity data spanning the study period. These results facilitated the identification of glaciers demonstrating surging behavior. Additionally, the study introduces a novel approach to analyzing glacier flow velocities, focusing on their acceleration characteristics.
