Data for: Holocene climatic conditions in the Eastern Adriatic recorded in stalagmites from Strašna peć Cave (Croatia)

Data present results of stable isotope analysis (δ18O, δ13C) of two stalagmites (SPD-1 and SPD-2) from Strašna peć Cave, situated on Dugi otok Island (Croatia in the central Adriatic region. The growth interval of the speleothems based on U-Th dating covers the period from 4.4 ka to 1.5 ka. Both speleothems show frequent δ18O and δ13C fluctuations with similar average values (δ18O value of -4‰ for both speleothems; and average value of δ13C-8.5‰ and -8.8‰, respectively).本数据集包含采自亚得里亚海中部克罗地亚境内杜吉奥托克岛（Dugi otok Island）斯特拉斯纳洞穴（Strašna peć Cave）的两根石笋（SPD-1与SPD-2）的稳定同位素分析（δ¹⁸O、δ¹³C）结果。经铀钍（U-Th）测年确定，该两根石笋的生长时段覆盖4.4 ka至1.5 ka区间。两根石笋均呈现出频繁的δ¹⁸O与δ¹³C波动，且平均同位素数值特征相近：二者的δ¹⁸O平均值均为-4‰；δ¹³C平均值则分别为-8.5‰与-8.8‰。
