来自洞穴的稳定同位素记录提供了关于过去气候变化的信息，尤其是可用于重建过去降水和大气环流变化的信息。这些记录越来越多地被用于提供同位素气候模型的“样本外”评估。SISAL（洞穴同位素合成与分析）是过去全球变化（PAGES）项目的一个国际工作组。该工作组旨在为气候重建和模式评估提供一个全面的岩洞同位素记录汇编。SISAL数据库包含单个洞穴主题的数据，按洞穴系统分组。氧和碳的稳定同位素（δ O-18, δ C-13）的测量是根据距离洞穴顶部或底部的距离来参考的。其他表格提供了关于年代的信息，包括用于构建原始年龄模型的日期信息，以及评估每个数据集质量和建立不同洞穴主题标准化年表的足够信息。元数据表提供了位置信息、对每个洞穴进行的所有测量的信息、与解释记录有关的洞穴系统信息，以及出版物和存档数据的引文。
Stable isotope records from speleothems provide information on past climate changes, most particularly information that can be used to reconstruct past changes in precipitation and atmospheric circulation. These records are increasingly being used to provide "out-of-sample" evaluations of isotope-enabled climate models. SISAL (Speleothem Isotope Synthesis and Analysis) is an international working group of the Past Global Changes (PAGES) project. The working group aims to provide a comprehensive compilation of speleothem isotope records for climate reconstruction and model evaluation. The SISAL database contains data for individual speleothems, grouped by cave system. Stable isotopes of oxygen and carbon (delta O-18, delta C-13) measurements are referenced by distance from the top or bottom of the speleothem. Additional tables provide information on dating, including information on the dates used to construct the original age model and sufficient information to assess the quality of each data set and to erect a standardized chronology across different speleothems. The metadata table provides location information, information on the full range of measurements carried out on each speleothem and information on the cave system that is relevant to the interpretation of the records, as well as citations for both publications and archived data.
