Northern South China Sea Planktonic foraminifera εNd from IODP Site U1501

This dataset contains a total of 68 εNd (neodymium isotopic composition) measurements derived from planktonic foraminifera collected at IODP Site U1501 in the northern South China Sea. The data span the past 28 million years (since ~28 Ma) and provide insights into long-term changes in water mass composition, regional tectonics, and continental weathering.本数据集共计包含68组εNd（钕同位素组成，neodymium isotopic composition）测量数据，所有数据均来自采自南海北部国际大洋发现计划（IODP）U1501站位的浮游有孔虫。该数据集覆盖过去2800万年（即约28 Ma）的时间跨度，可为水团组成、区域构造运动以及大陆风化作用的长期变化研究提供重要见解。
