Abstract

The Younger Dryas (YD) stadial represents the most abrupt climate change of the Earth's recent history. Thus, understanding its causes and different local responses is relevant for Quaternary paleoclimatology. We present a speleothem high-resolution proxy record of the Lateglacial to Early Holocene paleoclimate of the Cantabrian Cordillera (N Spain), a strategic location to evaluate the influence of North Atlantic events such as the YD on South-Western Europe. Fluorescence lamination, growth-rate, stable-isotope, and [Mg] records from stalagmite SIR-1 were dated using an age-depth model constrained by U-Th dates and annual-lamina counting. The YD is recorded as a prominent positive δ13C excu..

Funding Acknowledgements

Financial support was provided by grant ICT-Soplao-53.5.00.12.00 (IGME - Provincial Government of Cantabria Turismo del Nansa). Alfredo Argumosa (El Soplao-SL) greatly facilitated our research in the cave. Jaime MacLennan provided data from El Soplao weather station. Alredo Fernandez-Larios provided valuable EMP assistance and Lora Wingate kindly performed the stable isotope analyses. The highly constructive comments by Lisa Baldini, three anonymous QSR reviewers, and Editor Ana Moreno, greatly contributed to improve the manuscript.
