Daniela Popescu’s scientific contributions

The Black Sea level is dependent on global climate change and Global Ocean level, the water intake from the Danube, and the astronomical sea and wind regime. Bathymetric, seismic-acoustic and sedimentological studies made by GeoEcoMar on the Romanian Black Sea shelf permit the identification of three distinct units: the littoral zone, the inner shelf, and the outer shelf. The lithological studies of cores from the Mamaia barrier beach, corroborated with geomorphological data from the Romanian Black Sea shelf, allow the sequential reconstruction of paleogeographic and sedimentary environments during the Late Quaternary period. The main stages of the Danube Delta evolution during the Holocene were highlighted and dated using the corroboration of geomorphologic, structural, textural, geochemical, mineralogical, and faunal analyses, and radiocarbon dating. The absence of Mesolithic and Early Neolithic traces in Dobrogea is explained by environmental factors such as the flooding of paleorivers by waters from the western part of the Black Sea.
