World's biggest iceberg drifts towards Antarctic penguin island

The world's biggest iceberg, more than twice the size of London could drift towards a remote island where a scientist warns it risks disrupting feeding for baby penguins and seals.

. Andrew Meijers, Physical Oceanographer, British Antarctic Survey said "It's the biggest iceberg in the world at the moment. It was around 4,000 square metres last year, but it's been melting ever since, and so it's down to about three and a half thousand, but it's still bigger than any other bergs in the world. And they're quite rare, so megabergs of this scale do come loose, especially from the Weddell Sea, but on the scale of a few a decade."

The iceberg would reach the shallows continental shelf around South Georgia in two to four weeks. It could avoid the shelf and get carried into open water beyond South Georgia, or it could strike the sloping bottom and get stuck for months or break up into pieces, he added.
