Other Supplementary Material for this manuscript includes the following:

  • Code S1 (.pdf format). Python code used for Monte Carlo simulations to calculate uncertainty for PCO2 estimations by considering every parameter involved in the equations.
  • Data S1 (Microsoft Excel format). All data used to reconstruct PCO2 from the δ13Cphytane.
