    Envisat radar imagery confirms that the B-15A iceberg – the world's largest floating object – is adrift once more 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 Janauary 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.

    Funny how the world reads about and then overlooks or forgets about a state size chunk of ice breaking off a glacier ! Especially one that wants to head-but it's cousin .

    Probably would have lasted a few more millenia if it weren't for that internal combustion engine thingamajig !

    Harvest it for fresh water where needed ! How about blowing it into chunks and towing it somewhere usefull ?

    Far fetched I know , but there is a large resourse there that could be harvested somehow .
