When the Black Sea re-connected with the Sea of Marmara at about 9.5 ky BP, inflowing Mediterranean water increased the Black Sea level very gradually up to ∼−20 m, and in so doing, it raised the salinity of the basin and brought in the first wave of Mediterranean immigrants. These data indicate no major drawdown of the Black Sea after the Younger Dryas, and they do not provide evidence for any catastrophic flooding of the Black Sea in the Early Holocene.

The southern contribution of riverine input into the lake was essentially absent during glacial periods.

Records of some elements (Ca/K, Sr/Rb, Si/Al, La/Th, U/Th, CIW) from the bottom sediments of Lake Baikal during the last 0.5 Myr with a resolution of ∼ 2 kyr have also been obtained.

Between 16 and 13 ky BP, the Late Neoeuxinian lake (the Late Pleistocene water body in the Pontic basin pre-dating the Black Sea) increased rapidly from ∼−14 to −50 m (below the present level of the Black Sea), then rose gradually to ∼−20 m by about 11 ky BP.

At 11–10 ky BP (the Younger Dryas), it dropped to ∼−50 m. Fluctuations in the level of the Black Sea and Mesolithic settlement of the northern Pontic area.

activity ratio as a proxy for lake water composition shows that the uranium isotope disequilibrium has not stayed constant throughout this period: it varied greatly in response to regional climate.

The U activity ratio in Lake Baikal paleowaters was inferred to be high during interglacial time (∼ 1.85–2 during MIS 5.5 and the Holocene; ∼ 1.4–1.7 during MIS 5.1 and 5.3) and dropped to ∼ 1.16 ± 0.01 during glacial time.

This paper attempts to determine whether the preponderance of existing evidence sustains support for these Great Floods in the evolution of the Black Sea. More specifically, Mesolithic and early Neolithic archaeological data in southeastern Europe and Ukraine give no indications of shifts in human subsistence or other behavior at the time of the proposed catastrophic flood in the Early Holocene [Anthony, D., 2006.
