In the version of this article initially published, there was an error in the fifth paragraph of the Results, where in the text now reading “The regression fit is moderate when all data are included (R² = 0.58, n = 149), but it improves markedly once MIS 5 is excluded (R² = 0.91, n = 92; Fig. 3b),” “R²” = 0.91 appeared originally as “R² = 0.90.” There was also an error in the fifth paragraph of the Methods “Southern Ocean export productivity reconstructions” subsection, where the text now reading “PC1 of the biogenic opal records explains 57.98% of the total variance, while PC2 accounts for only 13.50% (Supplementary Fig. 5a). For the biogenic barium records, PC1 explains 70.11% of the total variance, with PC2 contributing just 9.92% (Supplementary Fig. 5b). In the combined records, PC1 accounts for 60.51% of the total variance, while PC2 explains only 10.07% (Supplementary Fig. 5c)” replaces the original text “PC1 of the biogenic opal records explains 53.614% of the total variance, while PC2 accounts for only 16.202% (Supplementary Fig. 5a). For the biogenic barium records, PC1 explains 68.203% of the total variance, with PC2 contributing just 11.496% (Supplementary Fig. 5b). In the combined records, PC1 accounts for 57.64% of the total variance, while PC2 explains only 11.654% (Supplementary Fig. 5c).”

In Supplementary Fig. 5, the numerical values were correct, but axis scales were presented incorrectly. In Supplementary Fig. 3, the correlation coefficients for all three stacks were incorrectly reported as ρ = 0.96. The correct values are ρ = 0.94 for the biogenic opal stacks, ρ = 0.98 for the biogenic barium stacks and ρ = 0.97 for the combined stacks. In Supplementary Fig. 10, the correlation coefficient was incorrectly reported as “R” rather than “r.” The Results, Methods and Supplementary Information are now updated in the HTML and PDF versions of the article.
