I think it's 1/7th above water.

You are correct. I plead Senoritis, CRS, OTD (Old Timer's Disease), and the Fifth (Amendment, not something bottled).

I know how you feel.

Besides being beautiful, what's fascinating is 1/7th of each one is underwater. Those puppies can be HUGE!

I assume you meant only 1/7th of each one is over the surface, not underwater. To be exact, 91.7% of an iceberg's mass is underwater.

From The Physics of Everyday Stuff - Icebergs:

The weight of an object is given by its mass times the acceleration of gravity, g = 9.8 m/s²:

W = Mg

The iceberg has weight Wi = Mig and the buoyant force is equal to the weight of the displaced water, Ww = Mwg. Furthermore, since the iceberg is floating, its weight exactly balances the buoyant force:
Ww = Wi
Mwg = Mig
Vwwg = Viig
Vw = i/w Vi

So, the fraction of ice underwater, Vw/Vi, is given by the ratio of densities i/w=0.917. Over 90% of an iceberg's volume (and mass) is underwater.

Safe assumption, Kari .

Hmm well I wasn't far wrong assuming it was a glacier eh?

Stunning pic the tip one and just out of interest take a look at this little hotdog we have close to down under Iceberg B-15 - Wikipedia, the free encyclopedia

Talking about HUGE!

That would make a lot of fresh water if they could drag it close to e.g. Africa.

Yes just imagine how much water that would be below the waterline because above is an unimaginable size - or was I should say.

i've seen a glacier calving small bergs from a few hundred yards away in a MLB, and we were thrown about the waves it generated. they're very impressive when the do that. equally impressive is grinding your way thru 10 ft of ice in the polar seas on an icebreaker with nothing else but white as far as you can see, except the occasional yellowed polar bear and possibly with him a splash of red and black seal.
