SYDNEY (AFP) – Australian authorities Friday issued a shipping alert over a gigantic iceberg that is gradually approaching the country's southwest coast.
The Bureau of Meteorology said the once-in-a-century cliff of ice, which dislodged from Antarctica about a decade ago before drifting north, was being monitored using satellites.
"Mariners are advised that at 1200 GMT on December 9, an iceberg approximately 1,700 kilometres (1,054 miles) south-southwest of the West Australian coast was observed," it said, giving the iceberg's coordinates.
"The iceberg is 140 square kilometres in area -- 19 kilometres long by eight kilometres wide."
Experts believe the iceberg -- known as B17B -- is likely to break up as it enters warmer waters nearer Australia, creating hundreds of smaller icebergs in a hazard to passing ships.
"It's still 1,700 kilometres away, so it's quite a long way away, it's not really on our doorstep yet but it's been heading steadily towards us," glaciologist Neal Young said Thursday.
