Ever seen an iceberg from top to bottom?

[Hagar]

I was just mailed this link. http://dovergrammar.co.uk/Gems/geography-iceberg.htm
Check it out & be amazed.

Now you know why the Titanic sank.

This photograph came from a Rig manager for Global Marine Drilling in St. John, Newfoundland.

They actually have to divert the path of these things away from the rig by towing them with ships.

In this particular case the water was calm and the sun was almost directly overhead so that the diver was able to get into the water and click this picture.

They estimated the weight at 300,000,000 tons

Cool!.......literally.  I believe many years ago (maybe it was the 1930s?) The military tried reducing icebergs by bombing them.  Didn't work too good from what I recall.

I have been on  iceberg patrol and what I understand is only Ten (10)Per Cent of the Iceberg is above water.

The rest is below water and can extend in all directions.

We flew these Patrols with Electras because the U.S. Navy had a problem with these aircraft....the wings kept falling off at low level.

 I remember seeing pictures like this when I was a kid, probably in encyclopedias, still a very cool pic.

AWESOME!!
It looks as if there it is hollow up inside?
I wonder if any sea creatures use that for a place to live?

SCARY!  :o

Awesome picture

Seem to remember playing Dover Grammar School at rugger a couple of times in my school career down in beautiful Kent (except for the M20 and the Channel tunnel building works...).

Those were the days (before student debt , mass drinking and everything else at university )

Sorry hager, you got fooled. Its a fake picture

Origins:   Charming story, but this picture is actually an image called "The Essence of Imagination," marketed by Successories, the "premiere source for motivational media."

This image was produced in 1999 by Ralph A. Clevenger, a professional nature and underwater photographer who is also a member of the faculty of the Brooks Institute of Photography in Santa Barbara, California. As Mr. Clevenger explained, this image is not a single photograph but a composite of four different photographs (not all taken in the same place):
The iceberg image is a digital composite that I designed to illustrate the concept of "what you see is not necessarily what you get". As an underwater photographer I knew that my "vision" of what a big iceberg looks like was impossible to get in reality so I had to create it. The image exists in nature but due to water visibility is not possible to capture on film.

There are 4 separate images involved; the sky, the background, the top iceberg (shot in Antarctica), and the underwater iceberg (shot above water in Alaska and flipped in the final composite).

Thanks Loomex. It wasn't only me. The photo is published on a school website. I still think it's an amazing image.

Tjose would also need to be mighty big ships come to think of it...

I don't know much about nautical matters but I know they do tow icebergs with ships. I'm not sure but it might be possible to move a huge one with a comparatively small ship. Once you got the thing moving it might take some stopping.

I remember a serious proposal some years ago for towing icebergs to the Middle East to provide fresh water. They would have to be large examples to make it worthwhile but it was apparently a practical idea. I don't remember the outcome but it never came to anything.

How could they get one of the really big ones through the straits of Gibraltar without it hitting the sea-bed?
Its still a cool pic even if it is a fake

[Woodlouse2002]

Remember that the water would distort the submerged part of the ice burg anyway so what you see there is bigger than it seems.

I understand that on average 2/3rds of an ice burg is generally below water.

Oh yeah, and the prospect of towing them, well, two tug boats are all thats needed to tow and manuver a super tanker. It won't take much just to shift an iceburg.

More like 7/8ths. Don't forget that image is a fake although the proportions might be fairly realistic..

How much of an iceberg is below water?

The "tip of the iceberg" expression can be explained as follows: Icebergs float because the density of ice (around 900 kg per cubic meter) is lower than that of seawater (around 1025 kg per cubic meter). The ratio of these densities tells us that 7/8 of the iceberg's mass must be below water. Usually icebergs are 20% to 30% longer under the water than above and not quite as deep as they are long at the waterline.
