Estimates put it at around 1,270 sq km. Greater London is about 1,500 sq km; the Welsh county of Monmouthshire is roughly 1,300 sq km. That’s big by any measure, although not as large as the monster A68 berg which calved in July 2017 from the Larsen C Ice Shelf on the western side of the Weddell Sea. That was originally some 5,800 sq km but has since shattered into many small pieces.
