Extended Data Fig. 10: Data assimilation reconstruction in the ‘Σg’ scenario for the PETM.
From: Coupled decline in ocean pH and carbonate saturation during the Palaeocene–Eocene Thermal Maximum

This figure presents the increase in SST during the PETM (a), the change in weight % CaCO3 (pre-PETM minus PETM, b), and ocean topography in cGENIE (c). Some cell grids show an increase in weight % CaCO3 (blue grids) during the PETM, including two in Siberian and Paleo-Tethys located in shallow water settings with a water depth of less than ~300 m.
