Short summary

We used satellite images at 50 m resolution to create near-daily maps of ice and open water for Hornsund fjord, Svalbard over 23 seasons from 2002–2025. We observed a gradual shortening of the sea ice season as well as a decrease in the average ice coverage over the years. Air temperature in autumn and winter controlled ice conditions in the fjord.
