The cores were collected using a short gravity sediment corer (Niemistö type). The upper layers (0-5 cm) of sediment cores were stained with the 80% ethanol solution of rose Bengal following the protocol (Schönfeld et al., 2012, doi:10.1016/j.marmicro.2012.06.001) and were used only for the microfossil analysis. The rests of the cores (below the 5 cm) were continuously sampled with the 1 cm step and were used for the loss on ignition (LOI), microfossil, X-ray fluorescence (XRF), and grain-size analyzes.
The XRF analysis was performed with the Olympus Vanta C Series XRF Analyzer on the wet sediments. The concentrations of chemical elements were recalculated for the dry weight of sediment samples following the method of Boyle et al. (2015, doi:doi:10.1007/978-94-017-9849-5_14). The ratios of elements were calculated using the concentrations for the wet weight.14.057719.691754.956355.6849Gdansk Basin, Baltic SeaArcona Basin, Baltic SeaBornholm Basin, Baltic SeaRussian Science Foundationhttps://doi.org/10.13039/50110000676922-17-00170Baltic Sea regional climate feedbacks on the key climate events of the Holocene in the North Atlantic
