In the 1940s, Turkish Historian, Hasan Umur, proposed that Ancomah, a mythical place near Trabzon, Turkey, was linked with the Atlantis Myth.
in the 1990s, Ryan and Pitman theorized that the Black Sea suffered a catastrophic flooding that probably inspired the story of Noah's flood.
In 2000, Robert Ballard undertook a marine expedition and found the remains of human habitation around 300 feet underwater in the Black Sea off the north coast of Turkey. The area flooded around 5000 BC.
Before 5500 BC, a great plain lay in the northwest at a former freshwater-lake. In 5510 BC, rising sea level topped the barrier at today's Bosporus.
There is currently no consensus on the nature of the flooding to the Black Sea. Western scientists tend towards a catastrophic model. Eastern scientists tend towards a fluctuated model. The idea of gradual change has been proposed but is the least popular among scientists.
In 2004, Siegfried and Christian Schoppe theorized that Atlantis was probably located in the Black Sea and identifed the Pillars of Hercules with the Strait of Bosporus.
They claim Orichalcum means the obsidian stone that used to be a cash-equivalent at that time and was replaced by the spondylus shell around 5500 BC, which would suit the red, white, black motif. The geocatastrophic event led to the neolithic diaspora in Europe, also beginning 5500 BC.
In 2006, Werner E. Friedrich proposed that events from Plato's Atlantis, the Deluge from the Bible and the events from the Epic of Gilgamesh all recounted the same catastrophic Eastern Mediterranean event. He too proposed that Atlantis was once in the Black Sea.
