“…8). Moreover, the gradual rise of BHP concentrations supports the hypothesis of slow inflow of Mediterranean Sea water (Aksu et al, 2002;Bahr et al, 2006;Hiscott et al, 2007;Mudie et al, 2007;Yanko-Hombach et al, 2007), and conflicts with a scenario of catastrophic marine inflow through the Bosporus (Ryan et al, 1997(Ryan et al, , 2003.…”

“…A sudden (within b1000 yr) inflow of a very large volume of marine Mediterranean waters occurred, resulting in an abrupt increase in salinity to their present-day euxinic values . Evidence for this inflow can also be found in the abrupt replacement of fresh to brackish species by marine species (Major et al, 2002b;Major et al, 2006;Hiscott et al, 2007;Marret et al, in press). Furthermore, hydraulic modelling shows that about 60,000 m 3 of water per second must have flowed into the Black Sea basin after the Bosphorus sill was breached and that it would have taken at least 33 yr to equalize water levels in the Black Sea and the Sea of Marmara (Siddall et al, 2004).…”

“…Between 8.5 and 7.5 kyr 14 C BP, the present-day conditions of the surface waters of the Black Sea were established abruptly as a result of the rapid flooding of the Black Sea by Mediterranean waters, as shown by dinoflagellate cyst records Hiscott et al, 2007;Marret et al, in press) and other data (Ryan et al, 1997. Simultaneously, widespread sapropel deposition began both on the continental slope and in the deep basin.…”

“…Authors who are against a late connection of the Black Sea to the Mediterranean sea are now publishing evidence of a late salinisation of the Black Sea obtained from their studies conducted on cores recovered on the Black Sea Turkish shelf, i.e. Hiscott et al (2007) explains that the Ostracoda of Caspian affinity indicate~5‰ salinity until~7.5 ka. Dinocysts and foraminifera confirm a low but rising salinity no later than~8.6 ka and a first major pulse of marine waters is recorded at around 8.46 ka BP by Marret et al (in press).…”

This paper presents a 3D geometric interpretation of very high resolution seismic Chirp profiles acquired on the Romanian shelf during ASSEMBLAGE European Project. The results provide a solid record of the Black Sea Last Glacial Maximum (LGM) water level fluctuations. This pseudo-3D seismic interpretation shows that the Black Sea lacustrine shelf deposits form a significant basinward-prograding wedge system. On top of these prograding sequences is a set of sand dunes that delineates a wave cut-terrace like feature around the isobath −100 m. Landward of this dune field are small depressions containing barkhan-like bodies. The upper part of the last prograding sequence is incised by anastomosed channels which end in the Danube (Viteaz) canyon which are also built on the lacustrine prograding wedge. Ten stratigraphic units were distinguished and correlated with analyses of cores retrieved from this area. The results demonstrate that the first eight sequences represent lacustrine prograding wedges, the ninth sequence is the dune system itself and the tenth is a marine mud drape which covers the entire continental shelf. The lacustrine prograding wedges represent a lowstand deposit characterised by forced regression-like reflectors mapped from the pseudo-3D seismic data. Their hinge point corresponds to the wave erosion surface mapped around −100 m isobath on the multibeam mosaic. Dated cores give age control on this lowstand period, which lasted from 11 to 8.5 kyr 14 C BP as implied by: (1) the continuously dry climatic conditions in the region inferred by high percentages of herbs and steppe elements determined from ASSEMBLAGE cores and, (2) the formation of dunes between 10 and 8.5 kyr 14 C BP on the desiccated north-western Black Sea shelf at −100 m and (3) all of these covered by a marine mud drape confirming that the dune system is no longer active. The buried, anastomosed fluvial channels that suddenly disappear below 90 m depth, and a unique wave-cut terrace between 95 and 100 mbsl on the outer shelf are also consistent with a major lowstand base-level at around −100 m water depth. Preservation of sand dunes and the occurrence of small, buried incised valleys mark a rapid transgression within less than a century during which ravinement processes related to the water level rise had no time to significantly erode the seafloor.

“…In the case of the Black Sea, the hypothesis of a rapid flooding around w7400 bce is still a controversial topic (Ryan et al, 1997;Görür et al, 2001;Hiscott et al, 2007;Yanko-Hombach, 2007 and review within; Lericolais et al, 2009). Scenarios proposed by Major (2006) and Lericolais et al (2009) rest on imprecise radiocarbon dating related to the hardwater effect discussed by Fontugne et al (2009).…”

a b s t r a c tPalaeogeographic changes of the North Black Sea area during Early to Middle Holocene (i.e. 12e4 ka BP) is of crucial interest in the understanding of the spread of the Neolithic to central and western Europe. It is also a good method to develop a framework for Pre-and Proto-historic societal adaptation to environmental changes. This paper describes Black Sea coastal geomorphological changes associated with sea level rise, delta progradation and delta lobe shifts modifying the living conditions and habitability in the Danube delta during Neolithic to Chalcolithic time. An archaeological and palaeoenvironmental chronological framework allows comparison between environmental and social data. The rhythms of these changes are discussed in the light of spatial changes in settlements. The Neolithic to Chalcolithic transition (i.e. Hamangia, Boian and Gumelnit¸a) shows rapid adaptation to geographical conditions. The Early Neolithic gap in the Dobroudja is potentially the result of a taphonomic bias related to coastal position change in a context of a rapid flooding event.
