Estimates put it at round 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 massive by any measure, though not as giant because the monster A68 berg which calved in July 2017 from the Larsen C Ice Shelf on the western aspect of the Weddell Sea. But even at 1 / 4 of the dimensions of A68, the Brunt block will must be tracked due to the long run danger it may pose to delivery. The US National Ice Center will give the brand new berg a designation in the end. Because it’s in the identical Antarctic quadrant (0-90W) as A68’s origin, the Brunt berg may also carry the letter “A” in its identify. It’s more likely to be known as A74.
