PC1 (a) and PC2 (b) timeseries of the original, corrected δ18O and δ13C + Ti records. Black lines show oxygen and orange lines show carbon isotope ratios, with age uncertainties in shading. The uncorrected PC2 (δ18O) shares similarities with PC1 of the δ13C + Ti records (c). Dashed lines show summer (red) and autumn (blue) insolation.
