Short summary
This study analyses multidecadal coastal bluff erosion at Deception Island, Antarctica, using historical aerial and satellite imagery (1956–2023). A non-linear shoreline change approach reveals heterogeneous and accelerating recession patterns. Logistic sigmoidal models outperform traditional linear methods, offering improved insights into periglacial coastal dynamics under climate change.
