From: Dating stalagmites in mediterranean climates using annual trace element cycles
A comparison between peaks identified using three difference PCA experiments (PCA A, B and Sr only) for stalagmites YD-S2 (A), LAB-S1 (B), and MND-S1 (C). Only the PC1 time series output from one transect is shown for clarity. All methods locate similar, in phase peaks, although the output from Sr only tends to be smoother and have fewer peaks.
