Colossal A23a Iceberg Stuck

Colossal A23a Iceberg Stuck

The world's largest iceberg, Colossal A23a (spanning 3,672 sq. km), is currently stuck approximately 70 km from South Georgia Island, potentially avoiding harm to local wildlife habitats.

A23a broke away from the Filchner Ice Shelf in Antarctica in 1986 and remained lodged in the Weddell Sea for over three decades before drifting northward toward South Georgia Island in 2020.

As it remains grounded, the iceberg's melting and the nutrients released may enhance marine food availability, benefiting the region’s ecosystem.

South Georgia Island: Administered by the UK as a British overseas territory, South Georgia is also claimed by Argentina.

Icebergs: Large floating masses of freshwater ice that break off from glaciers or ice shelves and drift in oceans or seas. Since ice is less dense than water, about 90% of an iceberg remains submerged, with only the top visible.
