Excellent stratigraphic control is key to understanding the timing of paleoceanographic events through critical climate intervals. Drill sites recovered the lower and middle Eocene, nearly the entire Oligocene, the Miocene from about 17 Ma, the entire Pliocene and much of the Pleistocene. The paleomagnetic properties are generally suitable for magnetostratigraphic interpretation, with well-behaved demagnetization diagrams, uniform distribution of declinations, and a clear separation into two inclination modes. Although the sequences were discontinuously recovered with many gaps due to coring, and there are hiatuses from sedimentary and tectonic processes, the magnetostratigraphic patterns are in general readily interpretable. Our interpretations are integrated with the diatom, radiolarian, calcareous nannofossils and dinoflagellate cyst (dinocyst) biostratigraphy. The magnetostratigraphy significantly improves the resolution of the chronostratigraphy, particularly in intervals with poor biostratigraphic control. However, Southern Ocean records with reliable magnetostratigraphies are notably scarce, and the data reported here provide an opportunity for improved calibration of the biostratigraphic records. In particular, we provide a rare magnetostratigraphic calibration for dinocyst biostratigraphy in the Paleogene and a substantially improved diatom calibration for the Pliocene. This paper presents the stratigraphic framework for future paleoceanographic proxy records which are being developed for the Wilkes Land margin cores. It further provides tight constraints on the duration of regional hiatuses inferred from seismic surveys of the region.completedStratigraphyApplied geophysicsalgaeanisotropyAntarcticabiostratigraphycalibrationCenozoicchronostratigraphyclimate changecontinental margindemagnetizationdiatomsDinoflagellataEoceneExpedition 318geophysical methodsgeophysical surveysHoloceneIntegrated Ocean Drilling ProgramInvertebrataIODP Site U1359IODP Site U1361magnetic declinationmagnetic inclinationmagnetic propertiesmagnetic susceptibilitymagnetostratigraphymarine methodsmicrofossilsnannofossilspaleo-oceanographypaleoclimatologyPaleogenepaleomagnetismpalynomorphsPlantaeProtistaQuaternaryRadiolariareconstructionseismic methodsseismic stratigraphySouthern OceansurveysTertiaryWilkes Landurn:org.iodp:exp:318urnlargerWorkCitationcampaignurn:org.iodp:exp:318:site:U1359urnlargerWorkCitationstudyurn:org.iodp:exp:318urnlargerWorkCitationcampaignurn:org.iodp:exp:318:site:U1361urnlargerWorkCitationstudyurn:org.iodp:exp:318urnlargerWorkCitationcampaignEnglishgeoscientificInformation135.4500144.0000-66.3000-63.1500
