The Black Sea deluge
is a hypothesized catastrophic rise in the level of the Black Sea
circa 5600 BC due to waters from the Mediterranean Sea
breaching a sill in the Bosporus
Strait. The hypothesis made headlines when The New York Times
published it in December 1996, shortly before it was published in an academic journal.NYT

in relatively small magnitudes, and does not necessarily presuppose that there occurred any sudden "refilling" events.
In 1997, William Ryan and Walter Pitman
published evidence that a massive flooding of the Black Sea occurred about 5600 BCE through the Bosporus
, following this scenario. Before that date, glacial
meltwater had turned the Black and Caspian
Seas into vast freshwater lakes draining into the Aegean Sea
. As glaciers
retreated, some of the rivers emptying into the Black Sea
declined in volume and changed course to drain into the North Sea
