Citation:	Li, Ke; Tian, Jun (2026): Neodymium isotope of bulk sediment from ODP Sites 181-1123 and 198-1208 [dataset]. PANGAEA, https://doi.org/10.1594/PANGAEA.988449
Abstract:	The table presents the 143Nd/144Nd ratios measured from bulk sediment at ODP Sites 181-1123 and 198-1208, together with corresponding sample identifiers, depths, and ages. These ratios were converted to εNd values using a chondritic reference of 143Nd/144Nd = 0.512638. All analyses were conducted using MC-ICP-MS at the State Key Laboratory of Marine Geology, Tongji University.
