Neodymium isotope compositions of authigenic and detrital sedimentary phases from sediment cores during SONNE cruise SO268/1 and SO268/2@en

he Neodymium (Nd) isotopic signature (εNd) has been widely used as a proxy to reconstruct past ocean circulation. Recently it has been increasingly questioned which archives can be reliably used to extract authigenic εNd used for the reconstruction of past ocean circulation and under which environmental conditions bottom seawater εNd are altered and the original water mass signature is overprinted. This dataset contains Nd isotope compositions of authigenic and detrital sedimentary phases from the abyssal Pacific Ocean, focusing on the behavior of the Nd isotope composition in oxic deep-sea sediments during early diagenesis.
