Noah’s Flood: New Evidence of Catastrophic Flooding in the Black Sea
Results from a July 2005 cruise in the Black Sea may settle a
longstanding debate over evidence of a megaflood in the Black Sea, the
so-called “Noah’s Flood.” Multibeam bathymetry and sub-bottom profiling
reveals ridges, some more than 12 meters (40 feet) high, and channels
formed by erosion of the seafloor. The channels and ridges organize
into a unique landform - a shelf fan, probably constructed by the
flood. Mud drifts are associated with many ridges on the shelf, a
phenomenon previously described only in the deep sea. At about 9,000
years ago, the Black Sea was a lake with a level lower than the ocean.
The catastrophic flood of saltwater from the Mediterranean Sea led to a
dramatic reorganization of the shelf seafloor close to the Bosporus and
favored an exceptional preservation of shorelines and coastal bedforms
elsewhere along the Black Sea shelf.
