Holocene lake water d18O variations are inferred from \nendogenic sedimentary calcite d18O based on comparisons with \nhistoric watershed discharge records and tree-ring reconstructions. \nDrought periods (i.e., drier winters and/or a more rain-dominated \nseasonal precipitation balance) generally correspond with higher \ncalcite d18O values, and vice-versa. Early to middle Holocene \nd18O values are higher, implying a rain-dominated seasonal \nprecipitation balance. Lower, more variable d18O values after \nca. 3500 yr ago indicate a snow-dominated but more seasonally \nvariable precipitation balance. The middle to late Holocene \nd18O record corresponds with records of El Niño Southern \nOscillation intensification that supports a teleconnection \nbetween Rocky Mountain climate and North Pacific sea-surface \ntemperatures at decade to century time scales. \n","author":null,"citation":"Anderson, L. 2011. \nHolocene record of precipitation seasonality from lake calcite \nd18O in the central Rocky Mountains, United States. \nGeology, Vol. 39, pp. 211-214, March 2011, doi:10.1130/G31575.1 \n","edition":null,"identifier":{"id":"10.1130/G31575.1","type":"doi","url":"http://dx.doi.org/10.1130/G31575.1"},"issue":null,"journal":"Geology","pages":null,"pubRank":"1","pubYear":2011,"reportNumber":null,"title":"Holocene record of precipitation seasonality from lake calcite  d18O in the central Rocky Mountains, United States","type":"publication","volume":null}],"reconstruction":"N","scienceKeywords":["hydrology"],"site":[{"NOAASiteId":"37360","geo":{"geoType":"Feature","geometry":{"coordinates":["39.7653","-107.3464"],"type":"POINT"},"properties":{"easternmostLongitude":"-107.3464","maxElevationMeters":"3255","minElevationMeters":"3255","northernmostLatitude":"39.7653","southernmostLatitude":"39.7653","westernmostLongitude":"-107.3464"}},"locationName":"Continent>North America>United States Of America>Colorado","mappable":"Y","paleoData":[{"NOAADataTableId":"19458","coreLengthMeters":null,"dataFile":[{"NOAAKeywords":["earth science>paleoclimate>paleolimnology>oxygen isotopes"],"fileUrl":"https://www1.ncdc.noaa.gov/pub/data/paleo/paleolimnology/northamerica/usa/colorado/bison2011.txt","linkText":"bison2011.txt","urlDescription":"Data","variables":[{"cvAdditionalInfo":null,"cvDataType":"PALEOLIMNOLOGY","cvDetail":null,"cvError":null,"cvFormat":"Numeric","cvMaterial":null,"cvMethod":null,"cvSeasonality":null,"cvShortName":null,"cvUnit":"centimeter","cvWhat":"depth variable>depth"},{"cvAdditionalInfo":null,"cvDataType":"PALEOLIMNOLOGY","cvDetail":null,"cvError":null,"cvFormat":"Numeric","cvMaterial":null,"cvMethod":null,"cvSeasonality":null,"cvShortName":null,"cvUnit":"calendar year before present","cvWhat":"age variable>age"},{"cvAdditionalInfo":null,"cvDataType":"PALEOLIMNOLOGY","cvDetail":null,"cvError":null,"cvFormat":"Numeric","cvMaterial":"geological material>identified mineral>carbonate","cvMethod":"isotope ratio mass spectrometry","cvSeasonality":null,"cvShortName":null,"cvUnit":"per mil VPDB","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O"}]},{"NOAAKeywords":["earth science>paleoclimate>paleolimnology>oxygen isotopes"],"fileUrl":"https://www1.ncdc.noaa.gov/pub/data/paleo/paleolimnology/northamerica/usa/colorado/bison2011.xls","linkText":"bison2011.xls","urlDescription":"Data","variables":[]}],"dataTableName":"BL001","dataTableNotes":null,"earliestYear":10201,"earliestYearBP":10201,"earliestYearCE":-8251,"mostRecentYear":-58,"mostRecentYearBP":-58,"mostRecentYearCE":2008,"species":[],"timeUnit":"cal yr BP"}],"siteName":"Bison Lake"}],"studyCode":null,"studyName":"Bison Lake, Colorado Holocene Calcite Oxygen Isotope Data","studyNotes":"Calcite oxygen isotope (d18O) data for the Holocene from\nBison Lake, northwest Colorado, USA.  \n\nCalcite-d18O ratios of bulk sediment 32um size fraction \nfrom continuous intervals of 0.25 cm from 0 to 5 cm depth, \nat 1.0 cm intervals from 5 to 69 cm depth and at spaced \nintervals of 2.0 cm from 69 to 300 cm depth. \n","version":"1.0","xmlId":"9312"}
