Extended Data Fig. 7: Data assimilation reconstruction in the ‘no CaCO3’ scenario for the PETM.
From: Coupled decline in ocean pH and carbonate saturation during the Palaeocene–Eocene Thermal Maximum
This figure presents the data assimilation reconstructions of SST (a), pCO2 (b), surface pH (c), CaCO3 (d), surface calcite saturation state (Ωcalcite, e), and surface aragonite saturation state (Ωaragonite, f) for both the pre-PETM and PETM intervals, represented by filled lines. These are contrasted with corresponding priors, depicted by unfiled lines. Color coding is as follows: blue for pre-PETM and orange for PETM. The analyses are based on a total of 10,000 realizations.
