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.
