A huge iceberg has broken off the Amery Ice Shelf in Antarctica. Dubbed D28, the iceberg is around 1600 sq km – about the size of Greater London. Approximately 30 km wide and 60 km long, it is estimated to weigh over 300 billion tonnes.
Captured by the Copernicus Sentinel-1 mission, the animation shows before and after images of the berg breaking away. It is estimated to have calved from the Amery Ice Shelf between 22 and 25 September.
Scientists say that this is the biggest calving of the Amery Ice Shelf in 50 years. Satellites will continue to monitor and track the iceberg, as it poses a threat for ships in the vicinity.
