From: Strontium to calcium ratio and oxygen isotopic coral records can exaggerate past decadal tropical climate variability

Fig. 3: Corrected versus uncorrected estimates of climate variation from coral geochemical tracers.

Standard deviation of Sr/Ca and δ18O records before and after correction via the stacked records method plotted against the SD of SST from OISSTv2. Each point represents the mean across records in a pair. The diagonal lines show the accepted literature values for the mean sensitivities of the two proxies (−0.06 mmol mol-1 K-1 for Sr/Ca 12, −0.22‰ K−1 for δ18O 36).
