jimminy_cricket quotes a report from the BBC: The Amery Ice Shelf in Antarctica has just produced its biggest iceberg in more than 50 years. The calved block covers 1,636 sq km in area — a little smaller than Scotland’s Isle of Skye — and is called D28. The scale of the berg means it will have to be monitored and tracked because it could in future pose a hazard to shipping. Not since the early 1960s has Amery calved a bigger iceberg. That was a whopping 9,000 sq km in area. Amery is the third largest ice shelf in Antarctica, and is a key drainage channel for the east of the continent. D28 is calculated to be about 210 meters thick and contains some 315 billion tons of ice.
