Planktonic foraminifera δ18O and Mg/Ca ratios are widely considered as a powerful proxy to reconstruct past seawater-column temperature in coastal upwelling regions. Due to the complexity in the interpretation of planktonic foraminifera δ18O data with respect to past seawater temperatures, temperatu...
