This dataset includes measurements on mixed layer planktonic foraminifera from IODP/ODP sites for boron isotopes and trace elements. Boron isotopes were measured after column chemistry and solution analyses on a Neptune multi collector ICPMS, while trace elements were measured on pre-columned aliquots of the same samples, using Element XR ICP-MS. Furthermore, the dataset includes the seawater pH and atmospheric CO2 calculated from B isotopes measurements and Mg/Ca-temperature estimates, for no-vital effect treatment (T. sac-vital effect corrections at Eocene d11Bsw conditions result in d11B offsets within analytical uncertainty), and no pH correction on Mg/Ca-temperature relationship (assuming T. sac like species). Carbonate system calculations incorporate MyAMI ion-pairing corrections (https://github.com/MathisHain/MyAMI), and surface Omega values specific for the Eocene and the paleo-latitude of the core location. Propagation of uncertainties for pH and CO2 is completed through 1000 Monte Carlo simulations.
