Integration of geophysical, biofacies, and sedimentological data from these ODP legs suggests that a very similar style of continental margin growth has occurred along the Antarctic continental margin. Data from the Antarctic continental margin suggest that the shelf aggrades ("upbuilds") during periods of ice front retreat, whereas the slope progrades ("outbuilds") during episodes of ice advance to the shelf break. Because other glaciated continental margins have glacial marine successions similar to that of the Antarctic continental margin, it may be that a common or "unified" model of glaciated margin deposition exists, regardless of latitude and geological age.completedQuaternary geologyAntarctic ice sheetAntarctic OceanAntarctic PeninsulaAntarcticaCenozoicclimate changecontinental margin sedimentationcontinental shelfcontinental slopecoresgeophysical methodsgeophysical profilesgeophysical surveysglacial environmentglaciomarine environmentLeg 119Leg 178Leg 188lithofacieslithostratigraphymarine environmentmarine sedimentationmiddle TertiaryOcean Drilling ProgrampaleoclimatologypaleoenvironmentPrydz BayQuaternaryreconstructionreflection methodssedimentationseismic methodsseismic profilesshelf environmentslope environmentSouthern OceansurveysTertiaryurn:org.iodp:exp:119urnlargerWorkCitationcampaignurn:org.iodp:exp:178urnlargerWorkCitationcampaignurn:org.iodp:exp:188urnlargerWorkCitationcampaignEnglishgeoscientificInformation-78.300085.5147-77.0000-49.2407Antarctic PeninsulaPrydz Bay
