Walter Clarkson Pitman III (21 October 1931 – 1 October 2019) was an American geophysicist and a professor emeritus at Columbia University. [1] His measurements of magnetic anomalies on the ocean floor supported the Morley–Vine–Matthews hypothesis explaining seafloor spreading. With William Ryan, he developed the Black Sea deluge theory.
In addition to the early Holocene "Noah's Flood" scenario proposed by Ryan, Pitman, Dimitrov, and their colleagues [4] [8] and the Caspian Sea overflow scenario of Chepalyga, [13] [14] the non-catastrophic progressive flood model (or gradual inflow model) has been proposed to explain the Late Quaternary sea level history of the Black Sea.

One possibility is that the Black Sea filled first, with excess freshwater flowing over the Bosporus sill and eventually into the Mediterranean Sea. There are also catastrophic scenarios, such as the "Black Sea deluge hypothesis" put forward by William Ryan, Walter Pitman and Petko Dimitrov.
In 1997, William Ryan and Walter Pitman of Columbia University published a theory that a massive flood through the Bosporus occurred in ancient times. They claim that the Black and Caspian Seas were vast freshwater lakes, but in about 5600 BC the Mediterranean spilled over a rocky sill at the Bosporus, creating the current link between the ...
