New Scientist Breaking News - World's largest iceberg 'goes bump in the night': "The world�s largest iceberg has finally crashed into a massive tongue of ice floating in Antarctic waters.
The predicted �collision of the century�- between the B15-A iceberg and the Drygalski ice tongue - had been expected to happen on 15 January 2005 in McMurdo Sound in the Ross Sea. But the icy colossus instead became stranded on a shallow seamount a few kilometres away from the 70-km-long tongue - starving penguins and blocking shipping supply routes to Antarctic bases.
Now, after breaking free in early April, the ice giant has finally scraped the side of the long-lived Drygalski ice tongue, an extension of the David glacier into the ocean. An image snapped by the European Space Agency�s Envisat satellite on 15 April shows a 5-km-long section of the ice tongue breaking off at its seaward end as the bottle-shaped iceberg brushes past."
