A23a: Monster iceberg just shy of a trillion tonnes

[VaughanJB]

Now this is a big iceberg. I can't imagine a trillion tons!

Satellite measurements show the frozen block has a total average thickness of just over 280m (920ft).
Combined with its known area of 3,900 sq km (1,500 sq miles), this gives a volume of roughly 1,100 cubic km and a mass just below a trillion tonnes.
The iceberg, which calved from the Antarctic coast in 1986, is about to drift beyond the White Continent.

These things bang and tear across the sea floor before finally wandering into shipping lanes. Yikes.
