Giant ice slabs set for collision

Two giant slabs of ice are about to hit each other in Antarctica, possibly with spectacular results, say Nasa experts. A 160km-long iceberg is heading on a collision course with a huge floating glacier in the sea near the US McMurdo Research Station. The B-15A iceberg should collide with the Drygalski Ice Tongue no later than 15 January 2005, though it is slowing. US space agency scientists are studying the iceberg's progress by monitoring satellite images of the region. See the amazing/worrying photographs and story.
