The SISAL database: a global resource to document oxygen and carbon isotope records from speleothems [PDF]
Earth System Science Data, 2018 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
