ESA’s Sentinel-1 Satellite Captures Images of World’s Largest Iceberg As It Breaks Away From Antarctica

An enormous iceberg has broken-off from the western side of the Ronne Ice Shelf in the Weddell Sea of Antarctica. The iceberg, dubbed A-76, measures around 1668 sq. miles (4320 sq km) in size – currently making it the largest iceberg in the world.

Spotted in recent images captured by the Copernicus Sentinel-1 mission, the iceberg is around 106 miles (170 km) in length and 16 miles (25 km) wide, and is slightly larger in area than the island country of Cape Verde in the Atlantic Ocean.

 

 

 

 

The enormity of the berg makes it the largest in the world, snatching first place from the A-23A iceberg (approximately 3880 sq km in size) which is also located in the Weddell Sea. In comparison, the A-74 iceberg that broke off the Brunt Ice Shelf in February earlier this year, was only 1270 sq km.

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.

Icebergs are traditionally named from the Antarctic quadrant in which they were originally sighted, then a sequential number, then, if the iceberg breaks, a sequential letter.
