SISAL (Speleothem Isotopes Synthesis and AnaLysis Working Group) database version 2.0

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. 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 second version of the SISAL database contains oxygen and carbon isotope measurements from 673 individual speleothem records, and 18 composites from 293 cave systems worldwide, and metadata describing the cave settings and age models of these records. This version also contains 2,138 alternative age-depth models constructed for 503 SISAL entities. In order to assure traceability, any presentation, report, or publication that uses the SISALv2 database should cite Atsawawaranunt et al. (2018; https://doi.org/10.5194/essd-10-1687-2018), Comas-Bru et al. (2019; https://doi.org/10.5194/cp-15-1557-2019) and Comas-Bru et al. (2020; https://doi.org/10.5194/essd-2020-39). If using individual sites, the literature citations for published work provided in the database should also be cited. Contact information of data contributors of unpublished data is also provided and these should be contacted when unpublished records are used on an individual basis.
