During marine isotope stage (MIS) 6, SST oscillated following a stadial-interstadial pattern but at lower intensities and rates of change than in the Dansgaard/Oeschger events of MIS 3. Some of the most prominent events occurred over MISs 5 and 7, after prolonged warm periods of high stability. Climate during the whole period was predominantly maintained in interglacial-interstadial conditions, whereas the duration of stadials was much shorter.completedQuaternary geologyalkenonesCenozoicclimate changecoresDansgaard-Oeschger cyclesForaminiferaGlobigerinaGlobigerina bulloidesGlobigerinaceaGlobigerinidaeinterglacial environmentinterstadial environmentInvertebrataketonesLeg 161marine sedimentsMediterranean SeamicrofossilsOcean Drilling ProgramODP Site 977organic compoundspaleoclimatologypaleotemperatureProtistaQuaternaryRotaliinasea-surface temperaturesedimentsupper QuaternaryWest Mediterraneanurn:org.iodp:exp:161urnlargerWorkCitationcampaignurn:org.iodp:exp:161:site:977urnlargerWorkCitationstudyurn:org.iodp:exp:161urnlargerWorkCitationcampaignEnglishgeoscientificInformation-1.5719-1.571936.015436.0154application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www.sciencemag.org/content/306/5702/1762.full.pdfdownload
