The champion has lost its title

On 26 May 2021 iceberg A-76 lost two big chunks of ice (now A-76B and A-76C) and, with them, the title of biggest iceberg on Earth. The title went back to A-23A at 3880 sq km.

Before its break, A-76 measured around 4320 sq km in size. The berg is around 170 km in length and 25 km wide, and it was slightly larger than the Spanish island of Majorca.

The iceberg was spotted by the British Antarctic Survey and confirmed from the US National Ice Center using Copernicus Sentinel-1 imagery. The Sentinel-1 mission consists of two polar-orbiting satellites that rely on C-band synthetic aperture radar imaging, returning data regardless of whether it is day or night, allowing us year-round viewing of remote regions like Antarctica.
