Special Edition in Quaternary Research on "New developments in speleothem paleoclimate and paleoenvironmental science"

After a successful PAGES Open Science Meeting session, with SISAL working group co-convenors Andrea ColumbuFranziska LechleitnerLaia Comas-BruYassine Ait Brahim and Yuval Burstyn,  Yassine Ait Brahim and Andrea Columbu will be organizing a special issue to be published in Quaternary Research on "New developments in speleothem paleoclimate and paleoenvironmental science".


Over the last two decades, speleothems have been increasingly applied for past climatic and environmental reconstructions for the last ca. 500 thousand years using the U-Th absolute dating method. However, recent improvements in the U-Pb dating methodology have already demonstrated that speleothem paleoclimate timeseries can be extended further back in time. Oxygen and carbon stable isotopes (δ18O and δ13C) are the most exploited measurements, allowing the investigation of an array of past climate and environmental variables such as temperature, rainfall amount, moisture provenance, and seasonality. Trace elements, clumped isotopes, and fluid inclusions are among the newest climate proxies being progressively applied to refine the speleothem-based paleoclimatic interpretations and to gain novel insights into past climatic and environmental dynamics. With the aim of presenting the most recent findings and advancements, this session welcomes speleothem-based paleoclimate and paleoenvironmental studies. We give special attention to records from underrepresented regions and/or time periods, as well as to novel approaches and/or techniques. We also welcome studies involving data-model comparisons, both using climate models as well as proxy system and karst geochemical models.
