Only one sample from the Oligocene equatorial Pacific (Sample 199-1219A-13H-3, 50-54 cm) contained any biomarkers of interest to paleoceanography. The only lipids identified in the remaining samples appear to be contaminants from drilling or subsequent handling. Sample 199-1219A-13H-3, 50-54 cm, contained alkenone biomarkers specific to haptophyte algae that are used for estimating past mean annual sea-surface temperature (maSST). If the Holocene calibration of maSST is appropriate for the Oligocene, the estimated equatorial temperature is > or =28.3 degrees C, or at least 3 degrees C warmer than modern equatorial maSST at a similar longitude.completedStratigraphybiomarkerscarbonCenozoicEoceneEquatorial Pacificexperimental studiesfatty acidsgeochemistrylaboratory studiesLeg 199lipidsmarine sedimentsOcean Drilling ProgramODP Site 1219ODP Site 1221Oligoceneorganic acidsorganic carbonorganic compoundsPacific Oceanpaleo-oceanographyPaleogenesea-surface temperaturesedimentsTertiaryurn:org.iodp:exp:199urnlargerWorkCitationcampaignurn:org.iodp:exp:199:site:1219urnlargerWorkCitationstudyurn:org.iodp:exp:199urnlargerWorkCitationcampaignurn:org.iodp:exp:199:site:1221urnlargerWorkCitationstudyurn:org.iodp:exp:199urnlargerWorkCitationcampaignEnglishgeoscientificInformation-143.4200-142.01007.480012.0200Data 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/199_SR/VOLUME/CHAPTERS/207.PDFdownload
