The table provides input data for model analysis. Pasquier et al. 2022 quantified the six major Nd sources controlling seawater Nd cycling and applied these data as input for their inverse model GNOM to analyze global Nd circulation. We extracted this dataset into table format to ensure reliability in GNOM analyses and to facilitate broader use. The data were gridded and normalized in the original study; for further details, see Pasquier et al. 2022.
