Correction to: Nature Geoscience https://doi.org/10.1038/s41561-020-0540-2, published online 2 March 2020.

In the version of the article initially published, Supplementary Table 1 was missing a column that has now been added to correct the DSDP labels; samples below 148.06 mbsf are from DSDP Hole 73-522A. The amendment does not impact the data or interpretation in the paper.
