Cave speleothems are highly sensitive to climate and are widely used to investigate past climate variability. Many researchers in Australia are now employing speleothems to find out more about the long-term behaviour of the Australian climate system, especially regarding ENSO. However, progress is inhibited by a lack of appropriate instrumentation capable of meeting the unique demands of speleothem research. Our new mass spectrometer will provide precise, rapid and low-cost isotope analyses of speleothem samples, and in doing so generate exciting and important palaeoclimate data, particularly in the area of pre-instrumental rainfall histories.

洞穴洞穴特征对气候高度敏感，被广泛用于研究过去的气候变化。澳大利亚的许多研究人员现在正在使用洞穴主题来发现更多关于澳大利亚气候系统的长期行为，特别是关于ENSO的行为。然而，由于缺乏能够满足洞穴石研究独特需求的适当仪器，进展受到阻碍。我们的新型质谱仪将提供精确、快速和低成本的洞穴样品同位素分析，并在此过程中产生令人兴奋和重要的古气候数据，特别是在仪器前降雨历史领域。
