This dataset includes all CT, density, and grain size analyses presented in Fig. S3 of Supplement 2 in Karstens et al. 2023 – published in Nature Communications. The data derive from two marine sediment cores from the Eastern Mediterranean: 1m long sections of POS-513-20 (36 °N, 26 °E) and POS-513-41 (36 °N, 27 °E) that contain volcaniclastic deposits from the Minoan eruption. These data were generated using a muffle furnace (bulk density), Mastersizer 3000 (grain size), and ProCon CT ALPHA scanner (CT data) in the EARTHLAB facility of the University in Bergen (UiB). All of these data are shown in Fig. S3 of Supplement 2, but also in Fig. 1 of the main text. Additional details may be found in our readme file. (2023-03-06).
