11 Dec 09 - A giant iceberg measuring 140 square km (54 square miles) - double the size of either Sydney Harbour or Manhattan - is headed for Australia.

 

The Bureau of Meteorology said the once-in-a-century cliff of ice broke off from Antarctica nearly 10 years ago.

 

Known as B17B, the mammoth chunk of ice - 12 miles long and five miles wide - is about 1,700 km (1,056 miles) off Australia's southwest coast, according to the country's Antarctic Division.

 

"B17B is a very significant one in that it has drifted so far north while still largely intact," said Australian Antarctic Division glaciologist Dr Neal Young, who spotted the slab using satellite images taken by NASA and the European Space Agency.

 

Dr Young said if the iceberg on its northward path, it would eventually break up into hundreds of smaller icebergs.

 

The smaller icebergs created when the larger berg break up could become shipping hazards if they float closer to shore.

 

Australian authorities have issued a shipping alert over the gigantic iceberg.

 

Dr Young said an iceberg the size of B17B had not been seen so far north since the days when 19th century clipper ships plied the trade route between Britain and Australia.

 

Originally three times its current size, the iceberg broke off Antarctica's Ross Ice Shelf in 2000 along with several others, and has since traveled thousands of miles and a third of the way around Antarctica.

 

It stayed completely still in one spot for about five years, but is now on the move again.

 

APRESSE.....
