ResumoScientists' affiliations.2022a, 2022b).The Christiana Basin is deeper than the Anhydros and Anafi Basins; its volcanosedimentary fill potentially recorded the earlier volcanic history of the CSK volcanic field (including the products of Christiana and early Santorini), as well as the younger Santorini and possibly the Milos Volcano to the west along the Hellenic volcanic arc.The now-extinct Christiana Volcano produced lavas and tuffs of unknown ages (Aarburg and Frechen, 1999).An ignimbrite found on Christiani Island (one of the two small islands of the Christiana Volcano), Santorini, and the nonvolcanic island of Anaphi, called the Christiani Ignimbrite, was identified (Keller et al., 2010).Site U1598 was chosen to complement the previously drilled Site U1591.The aim was to retarget a thick pumice layer found at Site U1591 (uppermost ~65 mbsf; Figure F2), for which we had insufficient samples for our scientific aims, to increase our recovery of the interval.The site addresses scientific Objectives 1-4 and 6 of the Expedition 398 Scientific Prospectus (Druitt et al., 2022). OperationsThe vessel arrived at Site U1598 on 24 January 2023 at 1945 h.The vessel was under full dynamic positioning (DP) control at 2015 h,
