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.","pubRank":"1"}],"site":[{"NOAASiteId":"58873","siteName":"Laacher See","siteCode":null,"mappable":"Y","locationName":"Continent>Europe>Western Europe>Germany","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["50.4167","7.267"]},"properties":{"southernmostLatitude":"50.4167","northernmostLatitude":"50.4167","westernmostLongitude":"7.267","easternmostLongitude":"7.267","minElevationMeters":null,"maxElevationMeters":null}},"paleoData":[{"dataTableName":"LaacherSee2021C14model","NOAADataTableId":"45980","earliestYear":13101,"mostRecentYear":13006,"timeUnit":"cal yr BP","earliestYearBP":13101,"mostRecentYearBP":13006,"earliestYearCE":-11151,"mostRecentYearCE":-11056,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/radiocarbon/laacher-see2021c14model.txt","urlDescription":"NOAA Template File","linkText":"Radiocarbon (14C) modelling result of matching Poplar 1 to the SWILM-14C record","variables":[],"NOAAKeywords":["earth science>paleoclimate>others"]},{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/radiocarbon/laacher-see2021.xlsx","urlDescription":"Excel File","linkText":"Laacher See Volcanic Eruption Radiocarbon, All Data","variables":[],"NOAAKeywords":["earth science>paleoclimate>others"]}]},{"dataTableName":"LaacherSee2021C14SWILM","NOAADataTableId":"45981","earliestYear":11300,"mostRecentYear":10954,"timeUnit":"14C yr BP","earliestYearBP":13182,"mostRecentYearBP":12895,"earliestYearCE":-11232,"mostRecentYearCE":-10945,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/radiocarbon/laacher-see2021c14swilm.txt","urlDescription":"NOAA Template File","linkText":"Radiocarbon dates from the Swiss Late Glacial Reference (SWILM-14C), plus trees KFK0352 and KFK0323","variables":[],"NOAAKeywords":["earth science>paleoclimate>others"]}]},{"dataTableName":"LaacherSee2021C14SWILMext","NOAADataTableId":"45982","earliestYear":11193,"mostRecentYear":10971,"timeUnit":"14C yr BP","earliestYearBP":13087,"mostRecentYearBP":12907,"earliestYearCE":-11137,"mostRecentYearCE":-10957,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/radiocarbon/laacher-see2021c14swilmext.txt","urlDescription":"NOAA Template File","linkText":"Extended Swiss Late Glacial Reference (SWILM-14Cplus) 14C record applied for wiggle-matching","variables":[],"NOAAKeywords":["earth science>paleoclimate>others"]}]},{"dataTableName":"LaacherSee2021C14trees","NOAADataTableId":"45983","earliestYear":11233,"mostRecentYear":10963,"timeUnit":"14C yr BP","earliestYearBP":13122,"mostRecentYearBP":12901,"earliestYearCE":-11172,"mostRecentYearCE":-10951,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/radiocarbon/laacher-see2021c14trees.txt","urlDescription":"NOAA Template File","linkText":"Radiocarbon dates from 3 trees","variables":[],"NOAAKeywords":["earth science>paleoclimate>others"]}]}]}],"reference":{"pastThesaurusSkos":"https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf","pastThesaurusExplorer":"https://www.ncei.noaa.gov/access/paleo-search/cvterms","gcmdKeywordThesaurus":"https://earthdata.nasa.gov/earth-observation-data/find-data/idn/gcmd-keywords"},"dataLicenseDescription":null,"dataLicenseUrl":null}
