Between March 23 and April 5, 2022, in the framework of ClimaLand project, the deep-drilling campaign took place in the lower Danube Floodplain and in Central and South Dobrogea. Deep (18 to 55 m) boreholes were drilled in coastal barriers of Saturn, Eforie and Midia, and in former lakes within the lower course of the Danube (at Jijila and Văcăreni).

The sedimentary sequences were taken in tubes of 1.5 meters long and 8 centimeters in diameter, both in transparent tubes and in black tubes (in order to be able to apply optically stimulated luminescence OSL dating on the quartz and feldspar particles). The plastic tubes will be sectioned longitudinally, described and samples will be taken for various analyzes (grain size, loss on ignition, geochemistry, 14C dating, pollen, etc.). The purposes of these drillings are multiple: i)  to supply proxies for the Holocene evolution reconstruction of the lower course of the Danube floodplaine (Văcăreni and Jijila), ii) to reconstruct the oscillations of the Black Sea level (Saturn, Midia), iii) to reconstruct the evolution of vegetation and paleoclimate in these area. These activities contribute to the objective  Reconstruction of past landscape changes in the lower Danube driven by Holocene climate change and sea-level oscillations.
