Short summary

The Antarctic Peninsula is a mountainous region containing an ice sheet and peripheral glaciers. Differences remain between the methods used to estimate its mass changes. We use thousands of digital elevation models derived from high resolution stereoscopic images to calculate a new estimate of mass changes. We find that between 2007 and 2021, the ice sheet lost -28±6Gt/a and its peripheral glaciers -14±3Gt/a. We highlight the importance of resolving fine-scale changes in complex coastal areas.
