Cross-spectral analysis of climate records discussed in the text. (A) Sea-level and SST, (B) SST and benthic δ13C gradient, and (C) SST and Ti/Ca record. Squared wavelet coherence between two time series was computed using the methods proposed by106. The 95% confidence level against red noise was calculated using the Monte Carlo method and is shown as a thick contour that encloses the significant sections. The light shading indicates the region possibly influenced by edge effects. Black arrows indicate the phase relationship between the two time series.
