Giant Iceberg Heading for Australia’s Coast
December 10th, 2009
The Ross Ice Shelf where B17B broke away.
A giant iceberg double the size of Sydney Harbour is heading towards Western Australia on a collision course.
The iceberg, imaginatively named B17B by scientists is currently 1000km south west of the Australia coast and is drifting, intact, pulled by the ocean current and winds. It’s the largest iceberg to have drifted so far North and remained in one piece. It currently measures 19km long by 8km wide.
Dr Neal Young, a glaciologist for the Australian Antarctic Division said that if the iceberg collided with the coast of Australia it could cause a tremor on a point 3 to 4 scale.
However there’s no need for Sydneysiders to panic just yet, it is thought that once the iceberg hits warmer waters it’ll break up into hundreds of smaller pieces, creating a shipping hazard but no major tremors.
The iceberg broke off Antarctica’s Ross Ice Shelf in 2000 where it was originally three times its current size. It drifted around Antarctica for a time before settling in one spot where it remained for 5 years. However, possibly upon reading our fantastic article on winter fun in Australia, it’s now on the move again and heading for the coast. If there’s a stray polar bear on there we hope he’s got his Australian visa ready or else he’ll be shipped off to Christmas Island!
Many other icebergs have been spotted along the Australian and New Zealand coasts in the past few weeks, but B17B is the biggest spotted since the 19th century.
Dr Young warns that with global warming, these large iceberg sightings could soon become a common occurrence as the sea temperatures rise and more giant blocks of ice break off the ice shelves in Antarctica.
But for now, sunbathing Aussies can rest in peace, sipping their cocktails on the beach and asking: “Do you want ice with that?”
