Foraminiferal U/Ca, Mn/Ca and Ce/Ce* data of core Y9 in the Southwest Pacific

This study reconstructs redox variations from sediment core Y9 (48°14'S, 177°21'E; 1267 m water depth) in the Southwest Pacific, utilizing proxies including U/Ca, Mn/Ca ratios and Ce anomalies of uncleaned foraminifera over the past 200 ka.本研究针对西南太平洋海域Y9号沉积物岩芯（南纬48°14′，东经177°21′，水深1267米），采用过去20万年以来未清洗有孔虫（foraminifera）的铀钙比（U/Ca）、锰钙比（Mn/Ca）及铈异常（Ce anomalies）等代用指标，重建了该区域的氧化还原演化历史。
