Extracting recent short-term glacier velocity evolution over southern Alaska and the Yukon from a large collection of Landsat data

Researchers have identified and tracked glacier surges and complex ice flow dynamics in the Saint Elias, Kluane, and Wrangell mountain ranges using a novel method to analyze short-term glacier velocity changes. By compiling a multi-temporal stack of velocity data from Landsat imagery with 32-day intervals, they captured within-season variations over a vast area (150,000 km²). The study's fuzzy voting scheme effectively filtered outliers, enabling the detection of surges and their propagation characteristics without improving accuracy or precision. This fully automatic approach is adaptable to any geographical region or satellite system, offering a robust tool for studying short-term glacier dynamics on a regional scale.
