Supporting Data for "Long-term coupling of deep ocean carbon storage and global climate over the past 4.5 million years"

Data S1 contains new trace metals data from ODP site 1208 from the late Pliocene and late Quaternary. Data S2 contains timeseries of binned benthic stable isotope values from ODP Sites 982, 807, 1208, and 883, calculated timeseries of binned Δδ13C values, and accompanying binned values of Prob-stack benthic δ18O (Ahn et al., 2017) and ΔGMST (Clark et al., 2024). Data S3 contains Δδ13C982-NPAC, compiled MPWP benthic stable carbon isotope data, and Δδ13C982-Site#,. Data S4 contains compiled Holocene and Last Glacial Maximum benthic stable carbon isotope data (Peterson et al., 2014) and Δδ13C982-Site#. Please see the main text of the article associated with these data for detailed information on their collection and / or calculation. Code S1 bins timeseries of geologic proxy data by marine isotope stage and was used to calculate the values in Data S2. Code S2 is an example of the code used to calculate the uncertainties in the Δδ13C982-NPAC values in Data S3. Please cite the following if you use these data: Novak, J. B., Abell, J.
