The Black Sea is one of the world's largest marginal seas, possessing a maximum water depth of 2250 m and an area over 420,000 km2 (Fig. 1a).The Black Sea links Europe with Southwestern Asia, while its water is the product of Eurasian rivers and rainfall mixing with immigrant Mediterranean saline flowing in through the Bosphorus.Due to its semi-isolation from the World Ocean,the Black Sea tends to amplify environmental changes,and thus its detailed and sensitive paleoclimatic record has become a focus of oceanographic research.It is also the world's largest anoxic basin,enabling sophisticated studies of marine oxygen depletion and the exploration of ancient shipwrecks preserved in near pristine condition.On the west,the Black Sea is connected to the Sea of Marmara through the relatively shallow Bosphorus Strait(average water depth 35.8 m).On the east,it lies adjacent to the Caspian Sea.Today,the Black Sea is isolated from the Caspian Sea,but geological and paleontological traces of periodic connections between the basins, most likely via the Manych-Azov-Kerch spillway have been clearly documented (Fedorov, 1978, 1982; Popov, 1983; Yanko, 1990; Chepalyga, 2003, 2006).These periodic re-connections were produced largely by climate change and sea-level fluctuations, leading to drastic modifications in basin morphology, salinity,biota,sedimentary and geochemical systems,as well as human settlement.
