在这里，我们使用来自高山斯班纳格尔洞穴(奥地利)的三个石笋的δ18O时间序列，它们彼此之间的距离很小，以构建最后9个KYR(COMNISPA)的精确日期、连续的δ18O曲线。由于洞穴温度较低，这种洞穴记录不受动力学同位素分馏影响。因此，δ18O的变化可以用过去的气候变化来解释。COMNISPA显示了全新世内的几次振荡，它们的时间和持续时间与其他阿尔卑斯山档案记录的一致。
Here we use the δ18O time‐series of three stalagmites from the high alpine Spannagel cave (Austria) which grew in small distance from each other to construct a precisely dated, continuous δ18O curve for the last 9 kyr (COMNISPA). This speleothem record is not influenced by effects of kinetic isotope fractionation due to the low temperatures in the cave. Thus, the variations in δ18O can be interpreted in terms of past climate change. COMNISPA exhibits several oscillations within the Holocene, and their timing and duration is in agreement with that documented by other alpine archives.
