Shipboard lithologic proxy measurements and shore-based determinations of CaCO (sub 3) revealed regular cycles that can be attributed to climatic forcing. Discovering drill sites with well defined magneto- and biostratigraphic records that also show clear lithologic cycles is rare and valuable and creates the opportunity to develop a detailed stratigraphic intersite correlation, providing the basis to study paleoceanographic processes and mass accumulation rates at high resolution. Here we present extensive postcruise work that extends the shipboard composite depth stratigraphy by providing a high-resolution revised meters composite depth (rmcd) scale to compensate for depth distortion within individual cores. The depth-aligned data were then used to generate stacked records of lithologic proxy measurements. Making use of the increased signal-to-noise ratio in the stacked records, we then proceeded to generate a detailed site-to-site correlation between Sites 1218 and 1219 in order to decrease the depth uncertainty for magneto- and biostratigraphic datums. Stacked lithologic proxy records in combination with discrete measurements of CaCO (sub 3) were then exploited to calculate high-resolution carbonate concentration curves by regression of the multisensor track data with discrete measurements. By matching correlative features between the cores and wireline logging data, we also rescaled our core rmcd back to in situ depths. Our study identifies lithology-dependent core expansion due to unloading as the mechanism of varying stratigraphic thicknesses between cores.completedStratigraphybiostratigraphycarbonatesCenozoicclimate changecorescorrelationcyclostratigraphyEquatorial PacificLeg 199lithostratigraphymagnetostratigraphyMioceneNeogeneOcean Drilling ProgramODP Site 1218ODP Site 1219Pacific Oceanpaleo-oceanographyPaleocenepaleoclimatologyPaleogeneTertiaryurn:org.iodp:exp:199urnlargerWorkCitationcampaignurn:org.iodp:exp:199:site:1218urnlargerWorkCitationstudyurn:org.iodp:exp:199urnlargerWorkCitationcampaignurn:org.iodp:exp:199:site:1219urnlargerWorkCitationstudyurn:org.iodp:exp:199urnlargerWorkCitationcampaignEnglishgeoscientificInformation-142.0100-135.22007.48008.5300Available only on CD-ROM in PDF format and on the Web in PDF or HTML
