摘要

In the Ny-Ålesund region of Svalbard, the glaciers serve as sensitive indicators of contemporary climate change. A study conducted in this area utilized Landsat-8 multispectral images and applied an image correlation method to estimate ice thickness using surface ice velocity and slope. The analysis covered seven glaciers in the Arctic region during 2015–2016, revealing significant variability in ice thickness and surface ice velocity, reflecting complex glacier dynamics. This research enhances our comprehension of the complexities of glacier behavior and their responsiveness to environmental shifts. The study conducted in the Ny-Ålesund region of Svalbard focused on the use of image correlation method on Landsat-8 multispectral images to analyze the behavior of seven glaciers in the area during 2015–2016. The results revealed significant variability in ice thickness and surface ice velocity, indicating complex glacier dynamics. The findings contribute to a better understanding of glacier behavior in a changing environment, with implications for regional climate systems and sea level fluctuations.
