Short summary
Polynyas are areas of open water in sea ice that are important for ocean life and climate. We developed a new method to automatically find polynyas using morphological patterns in Antarctic sea ice data. The method reliably detected both large and small polynyas, produced results consistent with existing approaches, and remained accurate despite data uncertainty. This approach offers a promising way to build consistent long-term records and improve future studies of changing polar environments.
