Black Sea deluge hypothesis

Black Sea today (light blue) and 7,600 years ago (dark blue)

The Black Sea deluge is a flood theory proposed by William Ryan, Walter Pitman, Petko Dimitrov, and their colleagues in 1997. It would have taken place around 5600 BCE.[1]

The theory

According to this theory, 7,600 years ago, the Black Sea was formerly a freshwater lake.[1] Later, the Mediterranean Sea’s water rised and breached a rocky sill in the Bosporus and flooded the lake, transforming the so-called “Black Lake” into a brackish inland sea. The event flooded 100,000 km2(39,000 sq mi) of land and significantly expanded the Black Sea shoreline to the north and west.
