(editor), Proceedings of the Ocean Drilling Program, scientific results, Antarctic glacial history and sea-level change; covering Leg 178 of the cruises of the drilling vessel JOIDES Resolution; Punta Arenas, Chile, to Cape Town, South Africa; sites 1095-1103; 5 February-9 April 1998178We present revised magnetostratigraphic interpretations for Ocean Drilling Program Sites 1095, 1096, and 1101, cored in sediment drifts located off the Pacific margin of the Antarctic Peninsula. The revised interpretations incorporate a variety of observations and results obtained since the end of Leg 178, of which the most significant are new paleomagnetic measurements from U-channel samples, composite depth scales that allow stratigraphic correlation between multiple holes cored at a site, and revised biostratigraphic interpretations. The U-channel data, which include more than 102,000 paleomagnetic observations from more than 13,400 intervals along U-channel samples, are included as electronic files. The magnetostratigraphic records at all three sites are consistent with sedimentation being continuous over the intervals cored, although the data resolution does not preclude short hiatuses less than a few hundred thousand years in duration. The magnetostratigraphic records start at the termination of Subchron C4Ar.2n (9.580 Ma) at approximately 515 meters composite depth (mcd) for Site 1095, at the onset of Subchron C3n.2n (4.620 Ma) at approximately 489.68 mcd for Site 1096, and at the onset of Subchron C2An.1n (3.040 Ma) at 209.38 meters below seafloor for Site 1101. All three sites provide paleomagnetic records that extend upward through the Brunhes Chron.completedStratigraphyAntarctic OceanAntarctic PeninsulaAntarcticabiostratigraphyBrunhes ChronCenozoicclastic sedimentscontinental risecorrelationdemagnetizationdepositional environmentdriftLeg 178magnetizationmagnetostratigraphymarine sedimentsMioceneNeogeneOcean Drilling Programocean floorsODP Site 1095ODP Site 1096ODP Site 1101paleoenvironmentpaleomagnetismPlioceneQuaternaryremanent magnetizationsedimentationsedimentation ratessedimentsTertiaryupper Mioceneupper QuaternaryWest Antarcticaurn:org.iodp:exp:178urnlargerWorkCitationcampaignurn:org.iodp:exp:178:site:1095urnlargerWorkCitationstudyurn:org.iodp:exp:178urnlargerWorkCitationcampaignurn:org.iodp:exp:178:site:1096urnlargerWorkCitationstudyurn:org.iodp:exp:178urnlargerWorkCitationcampaignurn:org.iodp:exp:178:site:1101urnlargerWorkCitationstudyurn:org.iodp:exp:178urnlargerWorkCitationcampaignEnglishgeoscientificInformation-78.2916-70.1540-67.3401-64.2220Available only on CD-ROM in PDF format and on the Web in PDF or HTML; access date Feb. 24, 2002application/pdfunknownSEDIS Publication Catalogue
