Short summary

Large tabular icebergs (ice islands) are symbols of climate change as well as marine hazards. We measured thickness along radar transects over two visits to a 14 km² Arctic ice island and left automated equipment to monitor surface ablation and thickness over 1 year. We assess variation in thinning rates and calibrate an ice–ocean melt model with field data. Our work contributes to understanding ice island deterioration via logistically complex fieldwork in a remote environment.
