Although tephra deposits of the LSE represent an important isochron for the synchronization of proxy archives at the Late Glacial to Early Holocene transition, uncertainty in the age of the eruption has prevailed. Here we present dendrochronological and radiocarbon measurements of subfossil trees that were buried by pyroclastic deposits that firmly date the LSE to 13,006 ± 9 calibrated years before present (bp; taken as ad 1950), which is more than a century earlier than previously accepted. The revised age of the LSE necessarily shifts the chronology of European varved lakes relative to the Greenland ice core record, thereby dating the onset of the Younger Dryas to 12,807 ± 12 calibrated years bp, which is around 130 years earlier than thought. Our results synchronize the onset of the Younger Dryas across the North Atlantic-European sector, preclude a direct link between the LSE and Greenland Stadial-1 cooling, and suggest a large-scale common mechanism of a weakened Atlantic Meridional Overturning Circulation under warming conditions. #------------------ # Publication # Authors: Baales, M., Bittmann, F., Kromer, B. # Published_Date_or_Year: 1998 # Published_Title: Verkohlte Bäume im Trass der Laacher See-Tephra bei Kruft (Neuwieder Becken): Ein Beitrag zur Datierung des Laacher See-Ereignisses und zur Vegetation der Allerød-Zeit am Mittelrhein. # Journal_Name: Archäologisches Korrespondenzblatt # Volume: 28 # Edition: # Issue: # Pages: 191-204 # Report_Number: # DOI: # Online_Resource: # Full_Citation: # Abstract: #------------------ # Publication # Authors: Kromer, B., Spurk, M., Remmele, S., Barbetti, M., Joniello, V. # Published_Date_or_Year: 1998 # Published_Title: Segments of Atmospheric 14 C Change as Derived from Late Glacial and Early Holocene Floating Tree-Ring Series # Journal_Name: Radiocarbon # Volume: 40 # Edition: # Issue: # Pages: 351-358 # Report_Number: # DOI: # Online_Resource: # Full_Citation: # Abstract: #------------------ # Publication # Authors: Baales, M. et al. # Published_Date_or_Year: 2002 # Published_Title: Impact of the Late Glacial eruption of the Laacher See volcano, central Rhineland, Germany # Journal_Name: Quaternary Research # Volume: 58 # Edition: # Issue: # Pages: 273-288 # Report_Number: # DOI: # Online_Resource: # Full_Citation: # Abstract: #------------------ # Publication # Authors: Reinig, F. et al. # Published_Date_or_Year: 2018 # Published_Title: New tree-ring evidence for the Late Glacial period from the northern pre-Alps in eastern Switzerland # Journal_Name: Quaternary Science Reviews # Volume: 186 # Edition: # Issue: # Pages: 215-224 # Report_Number: # DOI: # Online_Resource: # Full_Citation: # Abstract: #------------------ # Publication # Authors: Reimer, P.J. et al. # Published_Date_or_Year: 2020 # Published_Title: The IntCal20 Northern Hemisphere radiocarbon age calibration curve (0-55 kcal BP) # Journal_Name: Radiocarbon # Volume: # Edition: # Issue: # Pages: 1-33 # Report_Number: # DOI: # Online_Resource: # Full_Citation: # Abstract: #------------------ # Publication # Authors: Kaiser, K.F. # Published_Date_or_Year: 1993 # Published_Title: Beiträge zur Klimageschichte vom späten Hochglazial bis ins frühe Holozän: rekonstruiert mit Jahrringen und Molluskenschalen aus verschiedenen Vereisungsgebieten # Journal_Name: Ziegler # Volume: # Edition: # Issue: # Pages: # Report_Number: # DOI: # Online_Resource: # Full_Citation: # Abstract: #------------------ # Publication # Authors: Bronk Ramsey, C. # Published_Date_or_Year: 2008 # Published_Title: Deposition models for chronological records # Journal_Name: Quaternary Science Reviews # Volume: 27 # Edition: # Issue: # Pages: 42-60 # Report_Number: # DOI: # Online_Resource: # Full_Citation: # Abstract: #------------------ # Publication # Authors: Bronk Ramsey, C. # Published_Date_or_Year: 2009 # Published_Title: Dealing with Outliers and Offsets in Radiocarbon Dating # Journal_Name: Radiocarbon # Volume: 51 # Edition: # Issue: # Pages: 1023-1045 # Report_Number: # DOI: # Online_Resource: # Full_Citation: # Abstract: #------------------ # Funding_Agency # Funding_Agency_Name: # Grant: #------------------ # Site_Information # Site_Name: Laacher See # Location: Europe>Western Europe>Germany # Country: Germany # Northernmost_Latitude: 50.4167 # Southernmost_Latitude: 50.4167 # Easternmost_Longitude: 7.267 # Westernmost_Longitude: 7.267 # Elevation: #------------------ # Data_Collection # Collection_Name: LaacherSee2021C14SWILMext # Earliest_Year: 11193 # Most_Recent_Year: 10971 # Time_Unit: 14C Year BP # Core_Length: # Notes: Extended Swiss Late Glacial Reference (SWILM-14Cplus) radiocarbon (14C) record applied for wiggle-matching;
