Speleothems and other continental carbonates (e.g. travertines, pedogenic, lacustrine, subglacial and cryogenic carbonates) are important terrestrial archives, which can provide precisely dated, high-resolution records of past environmental and climate changes. The field of carbonate-based paleoclimatology has seen (1) continuously improving analytical capacity, supporting the compilation of detailed records of climate variability integrating established as well as novel and innovative techniques. (2) Long-term environmental monitoring campaigns facilitating the interpretation of high-resolution proxy time series from carbonate archives. (3) The continuous development of proxy-system models that can help understand the measured proxies, by describing processes such as water infiltration, carbonate dissolution, precipitation and diagenesis. (4) The development of proxy databases such as SISAL (Speleothem Isotope Synthesis and AnaLysis) which enable regional-to-global scale analysis of the relationship between the proxy and the environmental parameter using a variety of large data analysis and data-model comparison techniques.

Applied together, advancements in these cornerstones pave the way towards developing highly reliable and quantitative terrestrial climate reconstructions. This session aims to bring together integrated and interdisciplinary studies in order to better understand the precipitation environment of continental carbonates and the incorporation of climate-sensitive proxies at various time scales. We especially invite contributions that show progress in one of the four outlined domains, and welcome speleothem and carbonate-based modern and paleoenvironmental studies, including new records of past climatic changes. In addition, research contributing to current international co-ordinated activities, such as the PAGES working group on Speleothem Isotopes Synthesis and AnaLysis (SISAL) and others are welcome.
