The world's largest iceberg, Colossal A23a (3,672 sq. km), is stuck about 70 km from South Georgia Island, likely avoiding ecological harm to its wildlife habitats.
- A23a broke from the Filchner Ice Shelf (Antarctica) in 1986 and remained stuck in the Weddell Sea for over 30 years and started drifting north in 2020 towards South Georgia Island.
- Nutrients released from the iceberg’s grounding and melting may boost marine food availability, supporting the regional ecosystem.
- South Georgia Island: The UK administers South Georgia (also claimed by Argentina) as a British overseas territory.
- Icebergs: Icebergs are large floating masses of freshwater ice that break off (calve) from glaciers or ice shelves and drift in oceans or seas.
- Since ice is less dense than water, 90% of an iceberg stays submerged, with only the top visible.
