Overview
- NASA said Monday that satellite images from April 3 show A-23A reduced to small fragments in the South Atlantic.
- Analysts estimated the iceberg had shrunk to just over 170 square kilometers by March 27, down from more than 6,000 square kilometers in 2020.
- The berg drifted more than 2,300 kilometers into warmer waters north of South Georgia and moved under Argentina’s ice-monitoring authority in early February.
- Large pools of meltwater on the surface weakened the ice and likely hastened the final collapse.
- Iceberg A-23A calved from the Filchner Ice Shelf in 1986 and spent decades grounded in the Weddell Sea before resuming its drift around 2020.
