In neolithic times did the Mediterranean break through at the Bosphorus with a gigantic tsunami-like wave into what is now the Black Sea, destroying whole civilisations, and giving rise to the Noah legend? – maybe even the Atlantis legend? Probably not:

A geologist with the Woods Hole Oceanographic Institution (WHOI) and two Romanian colleagues report in the January issue of Quaternary Science Reviews that, if the flood occurred at all, it was much smaller than previously proposed by other researchers.

Using sediment cores from the delta of the Danube River, which empties into the Black Sea, the researchers determined sea level was approximately 30 meters below present levels—rather than the 80 meters others hypothesized.

“We don’t see evidence for a catastrophic flood as others have described,” said Liviu Giosan, a geologist in the WHOI Geology and Geophysics Department.  […]

Once the researchers dated and reconstructed the delta plain, they could determine sea level for the Black Sea. They found that the Black Sea level at the time of the flood was around 30 meters below present levels. Determining how much water poured over the Bosphorus sill remains problematic. There is no direct reconstruction of the sea level for the Marmara, but, according to Giosan, indirect methods put it at approximately 5 to 10 meters above the Black Sea level at the time of the flood.

“So if this is true, it means that the magnitude of the Black Sea flood was 5 or 10 meters but not 50 to 60 meters,” said Giosan. “Still, having flooded the Black Sea by 5 meters can have important effects, for example, drowning of the Danube Delta and putting an area of 2,000 square kilometers of prime agricultural land underwater. This has important implications for the archaeology and anthropology of southern Europe, as well as on our understanding of how the unique environment of the Black Sea formed.”

Well, what a disappointment.
