The world's largest iceberg has broken into pieces

The world's largest iceberg A23a has split into parts, its area has decreased by 1000 square kilometers. This was reported by the press service of the Arctic and Antarctic Research Institute.

During the Antarctic winter, the iceberg lost more than a third of its mass: in June, A23a occupied 2730 square kilometers, but now its area has decreased to 1750 square kilometers.

Currently, the giant is drifting just 70 kilometers north of South Georgia Island. Over the past few months, the iceberg has traveled about 930 kilometers, circling the island under the influence of ocean currents.

A23a broke off from the Filchner Ice Shelf in 1986. At the time of its formation, its area exceeded 4170 square kilometers. For three decades, it remained stationary in the Weddell Sea until it moved toward the open ocean in 2023. By early 2025, the iceberg approached South Georgia, where it ran aground for several months, but later resumed its movement.
