A-81 Reaches South Georgia
The Antarctic iceberg made a relatively quick exit from the Weddell Sea, only to slow at the edge of a remote island’s underwater shelf. The post A-81 Reaches South Georgia appeared first on NASA Science .
Iceberg A-81, measuring approximately 1,550 square kilometers (600 square miles), broke off from the Brunt Ice Shelf in January 2023 and remained in the Weddell Sea for over three years. The iceberg, drifting along the coast via the Weddell Gyre, finally reached South Georgia's shallow underwater shelf on October 20, 2026, as captured by the MODIS on NASA's Terra satellite.
