When you think of icebergs, you probably think of those large white objects you see in movies and pictures. In rare situations, they can also be seen in a different form. When the iceberg gets flipped upside-down, it looks like a giant shiny piece of ice that’s the color of the surrounding water.

How does it get flipped over and how can it stay that way when by definition 90% of the iceberg is under water? It is physically impossible.
Wow! That is cool blue! Thanks for the post!
Thanks, very interesting. Very cool coloring.

Only polar bears should play on Icebergs :)
Run aground and flipped by current.
That’s pretty neat.
Now all I need is a tanker of Wild Turkey, and a really, really big tumbler...
BTW, the Drake Passage is supposed to be some of the most (naturally) violent and dangerous waters on the planet. From what I’ve read/seen, along with icebergs, the area gets the equivalent of a Category 3 hurricane every 3-4 weeks. Rogue waves of fearsome intensity and size are also supposed to be an occasional threat.
The underwater portion melts over time. It then becomes top-heavy and unstable and flips over.
Oh, those poor polar bears ... they must have drowned.
The rotational moment of inertia of the iceberg changes in response to differential heating of the surface. When a particular facet of the iceberg becomes more buoyant, this has the effect of rotating that facet above the water.
The entire iceberg DOES NOT flip. Just enough of it to restore the [now] heavier side to the bottom. 90% is still below the water. It's a different 90%.
It is NOT rare. Happens all the time.
What is rare is when the newly exposed side is entirely an ice "vein" which is pure ice without compacted snow.
Amazing Beautiful. What a beauty to see one of God’s many creations on this Earth. That berg looks like a shiny floating Sapphire.
Instead of the tip of the iceberg that is normally above water, we may be seeing the bottom end, 90% of the iceberg still under water.
And as you asked, how did it get tipped over?
The water is warmer than the air, the bottom melts, the c/g shifts, and over she goes.
I hate to break it to you, but this is what happens when airplanes flush their blue water into the sea in wintertime. Then again, maybe airlines get their blue water by melting these icebergs.
Icebergs always need to balance their mass, and the mass is unstable as it is melting at different rates in different areas, pieces are breaking off, etc. If it becomes top heavy, it certainly can flip.
It might be too much polar bear poop making the iceberg top heavy!
Now, THAT would make a cool wallpaper right there...........
