Late Pleistocene evolution of the coastal barriers from the Western Black Sea shows a higher global sea-level position during MIS3 highstand, which requires a reappraisal of the existing reconstructions

Abstract

This work presents the multi-proxy results obtained on a deep drill (MID core, 52 m) carried on the Midia coastal barrier closing the Tașaul Lyman, the end-member of Casimcea river valley. Casimcea river is one of the oldest Black Sea tributaries, draining a large part of the Paleozoic Casimcea plateau. Sequence stratigraphy intercepted by MID core (which did not reach the bedrock) reveals a remarkable deep valley cut into the lowest sector due to its long-lasting shaping activity under the stress of major sea-level oscillations.
