Abstract: 

The main point of the study is the juxtaposition in the characteristics of the Black Sea, such as salinity and water level, for the last ~20,000 years. These characteristics have been depending on climate changes and geological events that occurred during this time interval. The Black Sea Basin has undergone significant ecological and geological changes since the end of the Pleistocene (following the Last Glacial Maximum). The study’s main motif is to synchronize events and data from previous and new studies. This study includes some new data on rice-like aragonite at the base of sapropel sediments and radiocarbon dating of reef mussels. A medium surface salinity curve for the Black Sea Basin is derived for the studied time period. The sudden change in salinity is associated with rapid increase in water level in the basin following the penetration of saltier waters through the Bosporus. The conclusion was drawn after comparing current hypotheses.
