1. Light grey bars represent the sapropel according to the dark intervals observed in original photo of Section IX from core M25/4-12. Dark grey bars represent the tephra layers (V-2 and V-0). The largest negative ? 18 O shift in our record marks the onset of sapropel S6 (Figure 6 and 10e-f). All Mediterranean sapropels show this characteristic feature;SST estimated using MAT; i-k) Absolute abundances of noteworthy calcareous nannofossils: C. pelagicus, H. carteri, and F. profunda, respectively,1955
2. Our high-resolution ? 18 O G. ruber record exposes a two-step nature for the negative shift at the S6 onset in the Ionian Sea;Vergnaud-Grazzini;although glacial meltwater input has also been discussed,1977
3. The first step coincides with a peak of cold-water, surface-dwelling foraminifera (Figure 10g), a prominent abundance peak of the calcareous nannofossil taxon C. pelagicus (Figure 4a and 10i), which is an indicator of colder water and high nutrient environments;�0 ; Cita;Figure 10h). Furthermore, increasing values of Relative References Abu,1971
