World’s Largest Iceberg Stranded in South Atlantic: Satellite Photo Reveals Details

Quick Summary

• The Antarctic iceberg A-23A, the world’s largest iceberg, remains stranded off the coast of South Georgia Island in the South Atlantic Ocean since Febuary 2025.
• Measuring 1,240 square miles (3,460 square km),it is twice the size of Greater London and nearly matches the size of South Georgia Island.
• Satellite data from ESA’s Copernicus Sentinel-3 indicate that A-23A is stuck on a shallow underwater shelf 45 miles (73 km) offshore.
• The iceberg calved from Antarctica’s Filchner-Ronne Ice Shelf in 1986 and traveled over 1,200 miles (2,000 km) north to its current location after breaking away from the seafloor in the early 2020s.
• Small ice fragments are observed floating around A-23A due to disintegration caused by warmer sea temperatures and weather conditions typical for icebergs this far north.
• The melting introduces fresh water into surrounding ecosystems, perhaps impacting biodiversity near South Georgia Island.
