Tracking A23a - ArcGIS StoryMaps
Welcome to the journey of Iceberg A23a, a colossal piece of ice that broke away from the Filchner Ice Shelf in Antarctica in 1986. For over three decades, A23a remained anchored in the Weddell Sea, but recent shifts in ocean currents have set it on a significant migration path.

A23a is a large tabular iceberg which calved from the Filchner–Ronne Ice Shelf in 1986. It was stuck on the sea bed for many years but then started moving in 2020. As of January 2025, its area is about 3,500 square kilometres (1,400 sq mi), which makes it the current largest iceberg in the world. [2] [3] [4]
