Flood discovered before the Flood

Drilling cores from the Black Sea prove flooding over 100, 000 years ago

The Black Sea is considered as a possible scene of the biblical flood. There is clear evidence that about 8, 000 years ago, powerful saltwater floods from the Mediterranean poured into the inland waters that were deeper at that time. But this flood was not the first: A team of scientists has now shown for the first time that it must have already come there about 130, 000 years ago, once to a flood.

During the last ice age in the time around 115, 000 to 10, 000 years ago, the Black Sea up to 2, 200 meters deep was a large freshwater lake and separated from the Mediterranean by the then dry Bosphorus. It was not until the melting of the mighty polar ice caps and the rise of the world's sea level that the Mediterranean could pour over the Bosphorus into the Black Sea, which was then about 100 meters lower, about 8, 000 years ago. The flooding of heavily populated coastal areas could have been the scene of the biblical flood.

In the rhythmic change of cold and warm times during the last centuries, however, there must have been repeated phases in which the sea level highs during the warm periods, the Black Sea was connected via the Bosphorus with the Mediterranean.

Drill core reveals saltwater intrusion

In May 2007, a group of oceanographers aboard the German research vessel Meteor under the direction of Christian Borowski of the Max Planck Institute for Marine Microbiology in Bremen discovered tangible evidence. During this expedition, the researchers discovered deposits up to 150, 000 years old undamaged and in their complete sequence. Earlier expeditions were unsuccessful in this respect, because in large parts of this Binnenmeers these sequences are not achievable by conventional drilling.

In the new cores, this older saltwater influence of over 100, 000 years ago clearly stands out from the more homogeneous gray-brown floury deposits: dark massive layers of organic material - a so-called sapropel - alternate with finely layered light layers, which are marine Calcarea skeletons exist. display

Seamless history of the Black Sea

"It is a real good fortune that with our expedition we have found a suitable place where the natural sediment sequence has been preserved undisturbed", says sea geologist Helge Arz from the Geo-Forschungs-Zentrum Potsdam, "because For many years our search for this proof has been unsuccessful. "

One of the objectives of the Meteor Expedition M72 / 5 was to gather data on the recent history of this inland sea and the climate of the adjacent land masses. "The fascinating thing about the new drill cores is that it allows them to track the recent history of the Black Sea without any problems. We do not yet know whether the saltwater inflows were accompanied by torrential flooding or perhaps extended slowly over several thousand years. However, our data shows that the natural spectacle of flooding with seawater has repeatedly occurred, "emphasizes Christian Borowski.
