Fig. 4: Measured δ¹¹⁴Cd_meas, modeled δ¹¹⁴Cd_cal(mix), and calculated δ¹¹⁴Cd_{cal(mix+remin)}plotted against measured [Cd].

Measured δ¹¹⁴Cd_meas data are represented by full colored circles with black borders, modeled δ¹¹⁴Cd_cal(mix) values based on water mass mixing from the eOMP-Monte Carlo model are shown as open circles with colored borders, whilst the calculated δ¹¹⁴Cd_{cal(mix + remin)} values from water mass mixing + remineralization (see Eq. 2 in main text) are denoted by crosses with colored borders. The errorbars for δ¹¹⁴Cd are 2sd. The symbol colors represent the dissolved oxygen deficiency, O₂-def (see text for definition). Only data for samples from depths between 101 and 1002 m are plotted in the figure. The data sources are provided in Supplementary Table 2. The errorbars for δ¹¹⁴Cd denote the 2sd precision.
