Black Sea anomalies?

Yes.
To demonstrate, I will soon post an image of the Bosphorus straits region using the original program, the 3D etopo5 version and 3D etopo2 version which I still need to work on. - at current sea levels.

This image is from the original program. I could do large, nearly continent-sized regions and then zoom down but the image quality was poor and the color gradients left a lot to be desired. In fact, this version shows better colors than the original when we were looking at various areas a while back. I made some improvements since then. I can alter the sea level from -10,000 meters to +10,000 meters in 1 meter increments. Want a biblical flood or want to dry up the oceans? I can do it.

This version uses exactly the same data set, but I converted to a 3D presentation using OpenGL. The visible area is fixed at 10 x 10 degrees so you can get an idea how much area it covers. This is more of a finished application and the sea-level can be raised or lowered interactively to the same extents as the previous version. I intend to do some more work on this version to improve the shading.

Recently I downloaded the etopo2 dataset from USGS/NOAA. It has better than twice the resolution and so, shows much more detail. Again this is a 10 x 10 area. I will add the dynamic controls later when I am happy with the graphics.

This is the same view but rotated so we are looking west - southwest. Also I have lowered the altitude of the camera.

These shots appear smaller on the forum than they really are and so some of the detail may appear to be missing. Actually the strait itself is so narrow, it is not visible even at 2 arc minutes resolution. It is the one of the narrowest commercial ship lanes in the world.

A little modern cold war history about the Bosporus. My father was a career army officer and my family lived in Turkey when I was a child.

One of the main reasons we paid Turkey so well to be NATO allies was the Bosporus controlled access to the Black Sea, which was the only Soviet warm water seaport that was open year round.

That part of th world was strategic all the way back to Neolithic times, and still is to this very day, as Turkey controls access to both Iran and Iraq.

Not to mention Turkey controls water into the Syria, and much of the middle east.

When we lived in Turkey, my father scouted passes into Iran and Iraq, but no one ever tought such remote wastelands would ever become importantly militarily

You are correct about the strategic importance of the narrow passage. Istanbul literally straddles the strait. There are only two bridges which span the passage. Take them out, and its a long way around the sea for truck or rail transport.

One more thing, but don't let the alternative-theory people know. If I lower the waters low enough, like 3000 meters, Atlantis rises out of the Atlantic about mid-way between Spain and Nova Scotia.

(I'm not kidding - it really does!)

Yeah but 3,000 meters would make a lot of ice cubes.

Yep, and this image here:

Looks remarkably like this one from a depth of 2000 meters:

And how do we get it?

your program that is.
(I wrote the above ant the end of the first page.)
That is just plain powerful.
Do we need to start an Alantis thread?

By an order of magnitude.

Actually the prominance shown above is part of the mid-atlantic ridge and at those depths, an entire chain of islands runs from somewhere around Iceland, southward and then east to Africa. If it was Atlantis (attention: I DO NOT believe this) then it must have been quite high at one time and the ridge dropped, or shifted to a lower elevation. If this happened quickly enough, it would have thrown a tsumani through the Med. Sea and crashing through the Bosphorus. All of the coasts from Spain to Russia would have been innundated as well as the African coast and North and South America. Now there's a flood of Biblical proportions!

Min, on the link I posted above, I think it discusses the mid-Atlantic ridge response to the weight of the ice caps during the LGM. It shows the rising and sinking (supposedly).

I'm still more inclined to think that Plato was just telling a story.
