For the last glacial period, ice core studies have revealed \nstrong coupling of the largest millennial-scale warm events in \nAntarctica with the longest Dansgaard-Oeschger events in Greenland \nthrough the Atlantic meridional overturning circulation. It has been \nunclear, however, whether the shorter Dansgaard-Oeschger events have \ncounterparts in the shorter and less prominent Antarctic temperature \nvariations, and whether these events are linked by the same mechanism. \nHere we present a glacial climate record derived from an ice core \nfrom Dronning Maud Land, Antarctica, which represents South Atlantic \nclimate at a resolution comparable with the Greenland ice core records. \nAfter methane synchronization with an ice core from North Greenland, \nthe oxygen isotope record from the Dronning Maud Land ice core shows \na one-to-one coupling between all Antarctic warm events and Greenland \nDansgaard-Oeschger events by the bipolar seesaw. The amplitude of the \nAntarctic warm events is found to be linearly dependent on the \nduration of the concurrent stadial in the North, suggesting that \nthey all result from a similar reduction in the meridional overturning \ncirculation. \n","author":null,"citation":"EPICA Community Members. 2006. \nOne-to-one coupling of glacial climate variability \nin Greenland and Antarctica. \nNature, Vol. 444, pp. 195-198, 9 November 2006. \ndoi:10.1038/nature05301","edition":null,"identifier":{"id":"10.1038/nature05301","type":"doi","url":"http://dx.doi.org/10.1038/nature05301"},"issue":null,"journal":"Nature","pages":null,"pubRank":"1","pubYear":2006,"reportNumber":null,"title":"One-to-one coupling of glacial climate variability  in Greenland and Antarctica","type":"publication","volume":null}],"reconstruction":"N","scienceKeywords":["Meridional Overturning Circulation (MOC)"],"site":[{"NOAASiteId":"20568","geo":{"geoType":"Feature","geometry":{"coordinates":["-75",".07"],"type":"POINT"},"properties":{"easternmostLongitude":"0.07","maxElevationMeters":"2892","minElevationMeters":"2892","northernmostLatitude":"-75","southernmostLatitude":"-75","westernmostLongitude":"0.07"}},"locationName":"Continent>Antarctica","mappable":"Y","paleoData":[{"NOAADataTableId":"19688","coreLengthMeters":null,"dataFile":[{"NOAAKeywords":["earth science>paleoclimate>ice core>oxygen isotopes"],"fileUrl":"https://www1.ncdc.noaa.gov/pub/data/paleo/icecore/antarctica/maud/edml2006d18o.txt","linkText":"edml2006d18o.txt","urlDescription":"Data","variables":[{"cvAdditionalInfo":null,"cvDataType":"ICE CORES","cvDetail":null,"cvError":null,"cvFormat":"Numeric","cvMaterial":null,"cvMethod":null,"cvSeasonality":null,"cvShortName":null,"cvUnit":"calendar kiloyear before present","cvWhat":"age variable>age>ice age"},{"cvAdditionalInfo":null,"cvDataType":"ICE CORES","cvDetail":null,"cvError":null,"cvFormat":"Numeric","cvMaterial":"hydrologic material>bulk ice","cvMethod":null,"cvSeasonality":null,"cvShortName":null,"cvUnit":"per mil VSMOW","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O"},{"cvAdditionalInfo":"ice volume","cvDataType":"ICE CORES","cvDetail":"corrected","cvError":null,"cvFormat":"Numeric","cvMaterial":"hydrologic material>bulk ice","cvMethod":null,"cvSeasonality":null,"cvShortName":null,"cvUnit":"per mil VSMOW","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O"},{"cvAdditionalInfo":"ice volume and elevation change","cvDataType":"ICE CORES","cvDetail":"corrected","cvError":null,"cvFormat":"Numeric","cvMaterial":"hydrologic material>bulk ice","cvMethod":null,"cvSeasonality":null,"cvShortName":null,"cvUnit":"per mil VSMOW","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O"}]},{"NOAAKeywords":["earth science>paleoclimate>ice core>oxygen isotopes"],"fileUrl":"https://www1.ncdc.noaa.gov/pub/data/paleo/icecore/antarctica/maud/edml2006d18o.xls","linkText":"edml2006d18o.xls","urlDescription":"Data","variables":[]}],"dataTableName":"EDML10-51k","dataTableNotes":null,"earliestYear":51350,"earliestYearBP":51350,"earliestYearCE":-49400,"mostRecentYear":10050,"mostRecentYearBP":10050,"mostRecentYearCE":-8100,"species":[],"timeUnit":"cal yr BP"}],"siteName":"EPICA Dronning Maud Land"}],"studyCode":null,"studyName":"EPICA Dronning Maud Land Ice Core 10-51 KYrBP d18O Data ","studyNotes":"Oxygen isotope (d18O) data from the EPICA Dronning Maud Land \nice core for the period 51,000 to 10,000 years before present.  \nAge is synchronized to 2005 Greenland Ice Core Chronology (GICC05) \nage model (Andersen et al. 2006, Rasmussen et al., 2006) via \nmethane synchronization. \n\n*EPICA Community Members (listed in alphabetical order): \nC.
