Kochi Core School for Asian Young Scientists 2019 took place for the first time from 13 to 20 November 2019 at the Kochi Core Center (KCC), Kochi, Japan with the support of the SAKURA Science Exchange Program of Japan Science and Technology Agency (JST). KCC is a joint institute of Kochi University and Japan Agency for Marine-Earth Science and Technology (JAMSTEC). The KCC is one of three repositories of the International Ocean Discovery Program (IODP) cores in the world. A wide range of state-of-the-art analytical instruments and scanning methods are available according to the high standards of IODP at KCC. One of the major goals of the KCC is to train the next generation of scientists and promote IODP-related sciences. To achieve this goal, KCC offers a unique training opportunity for Kochi Core School by providing laboratory and seminar facilities. Using a Late Quaternary core sample collected from the Tosa Basin (off Kochi), the training program was implemented in two parts: visual core description and specific measurement of core (physical property and paleomagnetic measurements, and stable isotope measurements of foraminifers). The results of core analysis in the training program showed changes in the turbidite system that developed in association with the sea-level rise and/or temporal changes in the stacking patterns of channelized deposits since after the Last Glacial Maximum period in the Tosa Basin. We will report the overview of the Kochi Core School as well as the sedimentary characteristics of the Late Quaternary core in the Tosa Basin.
