One of the largest ever recorded iceberg has broken away from Antarctica, and now the trillion-tonne iceberg poses a serious hazard to ships and marine life. Sciebntists were anticipating this to happen but since it is such a large chunk it may now pose a serious hazard to ships around the South Pole, scientists said on Wednesday.

The calving of the 5,800 square kilometre iceberg leaves the Larsen C Ice Shelf reduced in area by more than 12 per cent, and the landscape of the Antarctic Peninsula changed forever.

Icebergs calve from Antarctica all the time, but because this one is particularly large, its path across the ocean needs to be monitored as it could pose a hazard to maritime traffic.

The event occurred sometime between July 10 and yesterday, said researchers who had been monitoring the growing rift in the West Antarctic ice shelf for years. The iceberg, which is likely to be named A68, weighs more than a trillion tonne. Its volume is twice that of Lake Erie, one of the Great Lakes.

There is a risk that Larsen C may eventually follow the example of its neighbour, Larsen B, which disintegrated in 2002 following a similar rift-induced calving event in 1995.

"We have been anticipating this event for months, and have been surprised how long it took for the rift to break through the final few kilometres of ice," said Professor Adrian Luckman of Swansea University in the UK, who is also the lead investigator of Project MIDAS that has been monitoring the crack.

Difficult to predict iceberg's future
The iceberg is one of the largest recorded and its future progress is difficult to predict. It may remain in one piece but is more likely to break into fragments. Some of the ice may remain in the area for decades, while parts of the iceberg may drift north into warmer waters.
