Abstract:
The Neodymium isotope gradient between ODP Sites 130-807 and 181-1123 was calculated after interpolating both records at 5 kyr resolution using Acycle. NaN values indicate intervals without data. The age models follow Elderfield et al. (2012, doi:10.1126/science.1221294) and Feng et al. (2022, doi:10.1016/j.gloplacha.2022.103945).
