http://news.bbc.co.uk/2/hi/science/nature/7752650.stmThe iceberg that breaks off from this glacier is roughly
1.5 km (0.9 miles) wide and 0.9 km (0.6 miles) high.The event happened in July 2008 and took approximately 15 minutes; the frames of this video are taken at 10 second intervals.
Researchers describe in the journal Science how computer models allowed them to discover that the rate at which an ice shelf breaks into an iceberg is primarily determined by the rate at which it is spreading away from the continent.
They have also shown that narrower shelves should break away more slowly than wider ones.
