Abstract

Following International Ocean Discovery Program (IODP) Expedition 397, split archive halves from Site 397-U1385 were analyzed at 1 cm resolution using an Avaatech X-ray fluorescence (XRF) core scanner at the University of Cambridge (United Kingdom).The resulting Ca/Ti profiles were used to revise the composite depth scales of Integrated Ocean Drilling Program Sites 339-U1385 and 397-U1385.Expedition 339 recovered a nearly continuous sediment sequence to 151.5 meters below seafloor (mbsf ) at Site U1385, except for a gap spanning Marine Isotope Stage (MIS) 11/Termination V at 53.06 mbsf.This interval was successfully retrieved during Expedition 397, completing the 1.45 My section.The existing depth scale for…
