We show here the data that are associated to the paper: The medial offshore record of explosive volcanism along the central to eastern Aegean Volcanic Arc, part 2: Tephra ages and volumes, eruption magnitudes and marine sedimentation rate variations, submitted for publication at G-Cubed. Table 2 indicate the sedimentation rate at all core positions of the research cruise POS513 with RV Poseidon in 2017, including ages given by correlations to dated eruptions and newly estimated ages based on sedimentation rates.
