Benthic foraminiferal Li/Ca increases by 17% across the glaciation event in the early Oligocene, which likely reflects the increase in seawater saturation state evidenced by the concomitant deepening of the calcite compensation depth. Following the establishment of the Antarctic ice sheet, benthic foraminiferal Li/Ca bears a remarkable resemblance to the estimated oxygen isotopic composition of seawater, suggesting that during this time seawater saturation was largely controlled by glacioeustatically driven changes in shallow-water carbonate accumulation rates.completedStratigraphyGeochemistry of rocks, soils, and sedimentsalkali metalsalkaline earth metalsAnomalinidaeAntarctic ice sheetAntarcticaArctic Oceanbenthic taxabiochemistrycalciumcarbonate compensation depthCassidulinaceaCenozoicchemical ratiosCibicidoidescontrolscoresDeep Sea Drilling ProjectDSDP Site 305Foraminiferageochemistryglacial environmentglaciationglaciomarine environmenticehouse effectInvertebrataLeg 130Leg 199Leg 32Li/Calithiummarine environmentmarine sedimentsmetalsmicrofossilsNorwegian SeaOcean Drilling ProgramODP Site 1218ODP Site 806Oridorsalis umbonatusPacific Oceanpaleo-oceanographypaleoclimatologypaleoecologyProtistaRotaliinasaturationsedimentsurn:org.iodp:exp:130urnlargerWorkCitationcampaignurn:org.iodp:exp:199urnlargerWorkCitationcampaignurn:org.iodp:exp:32urnlargerWorkCitationcampaignurn:org.iodp:exp:32:site:305urnlargerWorkCitationstudyurn:org.iodp:exp:32urnlargerWorkCitationcampaignurn:org.iodp:exp:199:site:1218urnlargerWorkCitationstudyurn:org.iodp:exp:199urnlargerWorkCitationcampaignurn:org.iodp:exp:130:site:806urnlargerWorkCitationstudyurn:org.iodp:exp:130urnlargerWorkCitationcampaignEnglishgeoscientificInformation-135.2200159.21420.190632.0008
