Evolution of the Kronebreen glacier

The animation shows the yearly evolution of the Kronebreen glacier. The animation used a series of Copernicus Sentinel-1 data to classify the region into areas of glacier, iceberg and growler occurrences in Kronebukta (Krone Bay) during the summer months of July to September, from 2015 to 2023.

The red line in the animation shows the manually extracted glacier fronts from Copernicus Sentinel-2 images at the end of the summer by Moholdt et al. (2021) for the corresponding year as a comparison. Using this Sentinel-1 method provides a statistically defined composite of the summer glacier front positions and calving intensities, revealing the dynamic interactions between ice and ocean over time.
