Our data show a clear "Antarctic" timing of sea surface temperature changes, which appear systematically linked to meridional displacements in sea ice, westerly winds, and the circumpolar current system. Proxy data for ice sheet changes show a similar pattern as oceanographic variations offshore, but reveal a variable glacier-response time of up to approximately 1000 years, which may explain some of the current discrepancies among terrestrial records in southern South America.completedQuaternary geologyAntarcticaArgentinaCenozoicChileclimate changecurrentsDansgaard-Oeschger cyclesEast PacificForaminiferaglacial geologyiceice sheetsInvertebrataLeg 202marine sedimentsmicrofossilsocean currentsOcean Drilling ProgramODP Site 1233Pacific Oceanpaleo-oceanographypaleoclimatologyPatagoniaProtistaQuaternarysea icesea-surface temperaturesedimentsSouth AmericaSouth PacificSoutheast Pacificthermohaline circulationurn:org.iodp:exp:202urnlargerWorkCitationcampaignurn:org.iodp:exp:202:site:1233urnlargerWorkCitationstudyurn:org.iodp:exp:202urnlargerWorkCitationcampaignEnglishgeoscientificInformation-76.0000-74.0000-42.0000-40.0000application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www.sciencemag.org/content/304/5679/1959.full.pdfdownload
