Shows connection between South Atlantic IRD events and increase in North Atlantic deep water production with inferred warming during interstadials in North Atlantic. Subsequent sea-level rise may have released grounded ice shelves in Weddell Sea region.completedQuaternary geologyabsolute ageAntarctic ice sheetAntarcticabenthic taxaC-13/C-12C-14carbonCenozoicdatesForaminiferaice raftinginterstadial environmentInvertebrataisotopeslast glacial maximumNorth Atlantic Deep Waterocean circulationpaleo-oceanographypaleocirculationPleistoceneProtistaQuaternaryradioactive isotopessea-level changessediment transportSoutheast Atlantic Oceanstable isotopesupper PleistoceneEnglishgeoscientificInformation-180.0000180.0000-90.0000-61.0000Antarctica
