The data are analyzed to investigate mean, interannual, and seasonal temperature and salinity (evaporation/precipitation) variations in the Early Holocene. The record is nine years long. A section of a Porites colony, 310-M0007B-11R-2, was recovered from site M0007 at 57 m below sea level. Oxygen and carbon isotopic and Sr/Ca analyses and were performed. Isotopic values are reported in delta notation relative to the Vienna PeeDee Belemnite (VPDB) isotopic standard. The U-Th chemistry was performed in the High-Precision Spectrometry and Environment Change Laboratory (HISPEC) of the Department of Geosciences, National Taiwan University. U/Th results are included in Table A1, Delong et al. 2010. The coral geochemistry was converted from the depth domain to the time domain by assigning maximum (minimum) coral Sr/Ca to minimum (maximum) SST climatology, then linearly interpolating to monthly intervals; the Sr/Ca chronology was applied to the isotopic records.","onlineResourceLink":"https://www.ncei.noaa.gov/access/paleo-search/study/10424","difMetadataLink":"https://www.ncei.noaa.gov/pub/data/metadata/published/paleo/dif/xml/noaa-coral-10424.xml","isoMetadataLink":"https://www.ncei.noaa.gov/pub/data/metadata/published/paleo/iso/xml/noaa-coral-10424.xml","originalSource":null,"dataTypeInformation":"https://www.ncei.noaa.gov/products/paleoclimatology/coral-sclerosponge","studyCode":null,"scienceKeywords":null,"reconstruction":"N","contributionDate":"2010-06-23","entryId":"noaa-coral-10424","earliestYearBP":9469,"mostRecentYearBP":9460,"earliestYearCE":-7519,"mostRecentYearCE":-7510,"publication":[{"author":{"name":"DeLong, K.L., T.M.

Herein we report on one well-preserved fossil coral sample: a 13.6 cm long Porites sp. dated by uranium series techniques at 9523 ± 33 years. Monthly d18O and Sr/Ca determinations reveal nine clear and robust annual cycles. Coral d18O and Sr/Ca determinations estimate a mean temperature of ~24.3°C (~3.2°C colder than modern) for Tahiti at 9.5 ka; however, this estimate is viewed with caution since potential sources of cold bias in coral geochemistry remain to be resolved. The interannual variability in coral d18O is similar between the 9.5 ka coral record and a modern record from nearby Moorea. The seasonal cycle in coral Sr/Ca is approximately the same or greater in the 9.5 ka coral record than in modern coral records from Tahiti. Paired analysis of coral d18O and Sr/Ca indicates cold/wet (warm/dry) interannual anomalies, opposite from those observed in the modern instrumental record.","pubRank":"1"}],"site":[{"NOAASiteId":"37036","siteName":"IODP M0007","siteCode":null,"mappable":"Y","locationName":"Ocean>Pacific Ocean>Central Pacific
