STUDY NOTES: Geochemical data and chronologies are provided for four southwest Sulawesi stalagmites Provided Keywords: Tropical speleothems, multi-proxy, Mg/Ca, d18O, d13C, prior calcite precipitation, Indonesia, Indo-Pacific Warm Pool, glacial-interglacial paleoclimates
ABSTRACT SUPPLIED BY ORIGINATOR: Speleothem d18O is widely used as a proxy for rainfall amount in the tropics on glacial-interglacial to interannual scales. However, uncertainties in the interpretation of this renowned proxy pose a vexing problem in tropical paleoclimatology. Here, we present paired multi-proxy geochemical measurements for stalagmites from southwest Sulawesi, Indonesia, and confirm changes in rainfall amount across ice age terminations. Collectively, the stalagmites span two glacial-interglacial transitions, from ~380,000 to 330,000 and 230,000 to 170,000 years ago. Mg/Ca in the slow-growing stalagmites is affected by water moving through the karst and prior calcite precipitation, making it a good proxy for changes in local rainfall. When paired, Mg/Ca and d18O corroborate prominent shifts from drier glacials to wetter interglacials in the core of the Australasian monsoon domain. These shifts in rainfall occur 4,000-7,000 years later than glacial-interglacial increases in global temperature and the associated response of Sulawesi vegetation, determined by speleothem d13C. |
