From: Modern and sub-fossil corals suggest reduced temperature variability in the eastern pole of the Indian Ocean Dipole during the medieval climate anomaly

Figure 7

Various proxy records from Indonesia covering the MCA. (a) Spliced speleothem δ18O record (‰. VPDB)69, from Liang lunar cave, Flores (b) Lake sediment isotopic composition δDwax from Lake Lading East Java27. (c) Reconstructed δ18O seawater based on isotopic composition of marine sediment (foraminifers) from Makassar Strait, Sulawesi26. (d) Reconstructed SST based on Mg/Ca ratio in marine sediment from Makassar Strait, Sulawesi26. The data is filtered in 50 year bins26. Shaded grey box indicates the period of the Medieval climate anomaly (MCA). Dashed lines indicate linear trends during the MCA period. Red rectangles indicate the time period covered by high-resolution coral Sr/Ca and δ18O data.
