For detailed quantitative micropalaeontological analysis, specimens of planktonic foraminifera were picked from about 3g of dry marine sediment, taken from the 1-2 topmost centimeters of the cores. Each sample was disaggregated with a weak hydrogen peroxide solution, wet sieved through a 63 μm sieve, and left to dry at 50°C overnight. The dry residues were sieved through a 125 μm screen and split using an Otto micro-splitter into aliquots of at least 300 planktonic foraminifera specimens, which were identified using the taxonomy of Hemleben et al. (1989; doi:10.1007/978-1-4612-3544-6_2). Trilobatus sacculifer and Trilobatus trilobus were treated as two different morphotypes. As T. trilobus are regarded the T. sacculifer individuals without the sac-like final chamber. Following Aurahs et al., 2009 (doi:10.1111/j.1365-294X.2009.04136.x), we distinguish Globigerinoides ruber pink (var. rosea) as a distinct morphotype. For the white variety (var. albus), we follow the concept of Wang (2000; doi:10.1016/S0031-0182(00)00094-8) by distinguishing G. ruber sensu stricto (s.s.) and G. ruber sensu lato (s.l.) morphotypes. We further note that G. ruber s.s. is equivalent to Morphotype A (type “Normal”), while those specimens grouped as G. ruber s.l. correspond to the Morphotypes B and C (types “Platys”and “Elongate”) of Kontakiotis et al. (2017; doi:10.1016/j.jmarsys.2017.05.005) for the study area.
