This record covers a time span of ~ 1000 years from 15,700 to 14,700 yr BP (before 1950 AD) with an average sampling resolution of ~ 5 years. High amplitude ´18O variation in this record reflects abrupt changes in ISM activity during the last deglaciation and suggest an age for the onset of Termination 1a (T1a) at ~ 14,800 yr BP in the Indian sub-continent. This record shows evidence for strong changes in tropical climate during the last deglaciation. Coincident variability in VSPM4 ´18O with speleothems from southern China during Termination 1a suggests that these caves reflect fluctuations in ISM activity. The variance in ´18O amplitude reveals significant multidecadal variability in ISM activity. Our record reveals intervals of strong monsoon activity during the later phase of Heinrich event 1 (H1) and shows synchronous multidecadal variability between ISM and East Asian monsoon (EAM). Spectral analysis of ´18O time series in VSPM4 reveals solar forcing and strong oceanatmospheric circulation control on ISM dynamics during the studied time interval.","pubRank":"1"}],"site":[{"NOAASiteId":"60654","siteName":"Valmiki Cave","siteCode":null,"mappable":"Y","locationName":"Continent>Asia>Southcentral Asia>India","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["15.15","77.8167"]},"properties":{"southernmostLatitude":"15.15","northernmostLatitude":"15.15","westernmostLongitude":"77.8167","easternmostLongitude":"77.8167","minElevationMeters":"420","maxElevationMeters":"420"}},"paleoData":[{"dataTableName":"VSPM4 isotopes Lone2014 SISAL v3","NOAADataTableId":"54338","earliestYear":15696,"mostRecentYear":14697,"timeUnit":"cal yr BP","earliestYearBP":15696,"mostRecentYearBP":14697,"earliestYearCE":-13746,"mostRecentYearCE":-12747,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/speleothem/SISAL-v3/noaa_templates/Lone2014-VSPM4.txt","urlDescription":"NOAA Template File","linkText":"VSPM4 Speleothem Geochemical Data","variables":[{"cvDataType":"SPELEOTHEMS","cvWhat":"depth variable>depth","cvMaterial":null,"cvError":null,"cvUnit":"length unit>millimeter","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"depth_sample"},{"cvDataType":"SPELEOTHEMS","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>calendar year before present","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"interp_age"},{"cvDataType":"SPELEOTHEMS","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"geological material>identified mineral>carbonate>calcium carbonate>aragonite","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil VPDB","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"measurement precision is 0.1 per mil","cvFormat":"Numeric","cvShortName":"d18O_measurement"}],"NOAAKeywords":["earth science>paleoclimate>speleothems>oxygen isotopes"]}]}]}],"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}
