Chinese Satellite Images Show Antarctica’s Giant Iceberg A23a Entering Final Breakup

China's Fengyun‑3D satellite captured images showing the Antarctic iceberg A23a has shrunk to roughly 506 sq km and is now fragmenting in its final stage. Calved in 1986 at about 4,170 sq km, the iceberg’s ongoing breakup underscores the value of high‑resolution satellite monitoring and has implications for Southern Ocean circulation, ecosystems and maritime safety.
