Drift-aware sea ice thickness maps from satellite remote sensing

16 September 2025

The authors developed a new method to map Arctic sea ice thickness daily using satellite measurements. They address a problem similar to motion blur in photography. Traditional methods collect satellite data over 1 month to get a full picture of Arctic sea ice thickness. But in the same way as in photos of moving objects, long exposure leads to motion blur, making it difficult to identify certain features in the sea ice maps. The authors' method corrects for this motion blur, providing a sharper view of the evolving sea ice.
