Briefings

On October 20, 2026, NASA's Terra satellite captured Iceberg A-81 drifting near South Georgia Island in the South Atlantic Ocean. The berg, which had calved from the Brunt Ice Shelf in January 2023, reached the island's underwater shelf edge after a slow drift of over three years. It is the first documented instance of this specific iceberg approaching the remote island since 2025, where another berg broke apart. The event occurred during a period of rapid ice shelf instability, with multiple large icebergs calving from the Brunt Ice Shelf in quick succession.

Key points

• Iceberg A-81, approximately 1,550 square kilometers in size, reached the underwater shelf edge of South Georgia Island in late October 2026.
• The iceberg had been drifting for over three years since calving from the Brunt Ice Shelf in January 2023, following a period of stability until 2019.

Context

This event occurred during a period of rapid ice shelf instability, with multiple large icebergs calving from the Brunt Ice Shelf in quick succession. The image was acquired by NASA's Terra satellite using MODIS data, providing a snapshot of the berg's position relative to the island's underwater shelf.

Limitations

The evidence is limited to a single satellite image from October 2026. The specific speed of the berg's drift is not quantified, and the exact distance from the island's shoreline is not measured. The source does not provide data on the berg's current orientation or whether it has broken off from the shelf entirely.
