Giant Antarctic iceberg afloat again. (Larsen B)

European satellite Envisat radar imagery confirms that the B-15A iceberg – the world’s largest floating object – is adrift once more in Antarctic waters after two months aground on a shallow seamount.

This latest development poses a renewed threat to the nearby pier of land-attached ice known as the Drygalski ice tongue.
The sheer scale of B-15A is best appreciated from space. The bottle-shaped Antarctic iceberg is around 120 kilometres long, with an area exceeding 2500 square kilometres, making it about as large as the entire country of Luxembourg.

Back in January the iceberg appeared to be drifting towards the 70-kilometre-long Drygalski ice tongue in McMurdo Sound on the Ross Sea, and an unprecedented ice collision looked imminent.

However B-15A eventually slowed down and stopped. Local bathymetry charts suggested the iceberg had become anchored at a point near the middle of its coastward (or western) side to a shallow section of seabed.

But it looks like the grounding slowed it up a bit;

""It was now achieved a critical overlap with the end of the Drygalski ice pier, so far without touching. It would now appear that any contact – if at all – between the drifting iceberg and the land-fast floating ice tongue is likely to be a consequence of being ’brushed’ or ’bumped’ by the broader trailing end of the iceberg, much like the wide turns made by a long trailer behind a truck or the stern of a ship."

Mr. Drinkwater adds that the tidal current oscillations in the cross-shelf – or approximately east-west – direction may not be large enough to force a significant impact."

Would have been cool though...
