Sediment analyses included determination of sediment type, carbonate content, bulk stable oxygen isotope composition, and calcareous nannofossil zones. Glacial periods, identified by elevated bulk delta 18O, are characterized by darker sediment color, coarser grain size, and lower carbonate content, whereas interglacial periods yield lighter-colored, finer, and carbonate-rich sediments. These data from the shallowmost few meters of Marion Plateau sediments complement the subsurface information of Leg 194 holes, in which the top few meters have not been analyzed in such a high-resolution fashion. In addition, these gravity cores are more likely to have recovered the sediments closest to the sediment/water interface as compared to the hydraulic piston cores collected during Leg 194.completedQuaternary geologyalgaebiostratigraphyCenozoicCoral Seacoresdepositional environmentHoloceneisotope ratiosisotopesLeg 194marine sedimentationmarine sedimentsMarion PlateaumicrofossilsnannofossilsO-18/O-16Ocean Drilling ProgramoxygenPacific Oceanpaleo-oceanographypaleoclimatologyPlantaePleistoceneQuaternarysedimentationsedimentsSouth PacificSouthwest Pacificstable isotopessurveysupper PleistoceneWest Pacificurn:org.iodp:exp:194urnlargerWorkCitationcampaignEnglishgeoscientificInformation151.4500153.0500-21.0500-20.1000Data report; available only on CD-ROM in PDF format and on the Web in PDF or HTMLapplication/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/194_SR/VOLUME/CHAPTERS/006.PDFdownload
