Table 4: List of the adopted tie-point used to assess the age model. From the left, the depth in mbsf; the age in ka; the indication of
the tie-points’ sequence. IS 2-IS 18 refers to the sequence of Interstadials, the tie-points used for the last glacial period. S 20-S 26 refers to the sequence of Stadials, the tie-points used for MIS 5.
