Newshub today.  It weighs much as 6 small cars? Wow.

 

 

 

The world's largest iceberg is about to enter the open ocean.

 

The iceberg called A-68 originally broke free from Antarctica's Larsen Ice Shelf in 2017 and weighs 12,000 kg.

 

When the iceberg broke off the glacier, an act called "carving", the A-68 had an area of about 6000 sq km, about six times larger than Auckland.

 

Scientists will be watching the iceberg's movements as the A-68 could be a threat to ships out on the open ocean.

 

 

Actually, it's called "calving".

 

Weighing 12,000kg, so that's 12,000 litres = 12 cu metres, plus 4% for ice being less dense than water. (Can we get it to Auckland before the reservoirs run dry?)

 

And an area of 6,000 sq km = 6 Billion sq metres, so 12/6E9 = 2nm = 7 molecules thick.

 

Somehow I don't see this as a threat to shipping.

 

 

 

Pretty sure that an iceberg floating in water weighs precisely nothing - so the Herald article was only out by a tiny fraction of the total mass..
