Comparison of stalagmites LR06-B3 and LR06-B1 (a) δ18O, (b) δ13C, (c) Mg/Ca (cyan) and Sr/Ca (red), (d) LLPC1 (black line) and [234U/238U]i (purple dots: LR06-B3; blue dots: LR06-B1; dashed line: cubic spline fitted to the data) and (e) LLPC2. We interpret higher (lower) values in LLPC1 and [234U/238U]i in d to reflect drier (wetter) conditions. Mg/Ca and Sr/Ca records were previously reported in Griffiths et al.14. The PC factor loadings for each time series of PC1 and PC2 are shown in parentheses. PC1 accounts for 50% of the variance and PC2 accounts for 20%. Colour-coded symbols along the bottom indicate U-Th ages (purple: LR06-B3; blue: LR06-B1) and their associated 2σ uncertainties. The grey shading in d,e indicates the 95% bootstrap confidence interval. Vertical bars indicate the approximate timing of the Medieval Climate Anomaly (MCA; yellow), Little Ice Age (LIA; blue) and Current Warm Period (CWP; pink) in Flores, defined by decreased AISM rainfall during the MCA and CWP, and increased AISM rainfall during the LIA.
