First, the drilling was designed to develop modern age models and cross-calibrate biostratigraphy, magnetostratigraphy, isotope stratigraphy, and physical stratigraphy of the equatorial Pacific in order to form a chronologic framework of events. Second, specific intervals were targeted to constrain important paleoceanographic change. Three boundaries were targeted in particular: the Paleocene/Eocene (P/E) boundary, Eocene/Oligocene (E/O) boundary, and the late Oligocene and Oligocene/Miocene (O/M) boundary. Third, comprehensive time series studies were carried out on long intervals of Paleogene core to understand the long-term evolution of the equatorial Pacific, including changes in productivity, marine chemistry, temperature, and ice volume. The scientific goals were achieved through a drilling transect that crosses the position of the 56-Ma Pacific equator with an additional drill site (Site 1218) located at the 40-Ma Pacific equator.completedStratigraphyalgaebiostratigraphycarbonate compensation depthCenozoicchemostratigraphycorescyclostratigraphydiatomsEoceneEquatorial PacificgeochemistryInvertebrataLeg 199lithostratigraphylower CenozoicmagnetostratigraphymicrofossilsMioceneNeogeneOcean Drilling ProgramOligocenePacific Oceanpaleo-oceanographypaleoclimatologyPaleogenePlantaeplate tectonicsProtistaRadiolariaseismic stratigraphyTertiaryurn:org.iodp:exp:199urnlargerWorkCitationcampaignEnglishgeoscientificInformation-148.0000-135.00007.450026.0500Also available 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/SYNTH/SYNTH.PDFdownload
