A trend of increased sea-surface temperatures during the interglacial periods is present in the record beginning at isotopic Stage 11 and ultimately leading to the lightest delta (super 18) O values in isotopic Stages 9, 5, and 1. Maximum delta (super 18) O values are recorded during glacial isotopic Stages 6 and 8. Stable isotopic variability increased during the Brunhes Chron at the 100-ka time scale. The large amplitude changes can best be explained by global and regional ocean circulation changes. Increased strengthened return flow of warm salty water from the Pacific may have occurred during interglacial periods since isotopic Stage 11, which was largely reduced during glacial periods. The large climate fluctuations had a profound effect on the shallow-water carbonate production of the Great Bahama Bank. The aragonite content of the sediments shows fluctuations that follow the delta (super 18) O record. The leeward side of the Great Bahama Bank received increased input of platform material during sea-level highstands when the sea-surface waters were warm.completedQuaternary geologyIsotope geochemistryaragoniteAtlantic OceanbiochemistryBrunhes ChroncarbonatesCaribbean SeaCenozoicclimate changeconcentrationForaminiferageochemistryGlobigerinaceaGlobigerinidaeGlobigerinoidesGlobigerinoides ruberGreat Bahama BankInvertebrataisotope ratiosisotopesLeg 166middle QuaternaryNorth AtlanticO-18/O-16Ocean Drilling ProgramODP Site 1006oxygenpaleoclimatologyProtistaQuaternaryRotaliinasalinitystable isotopestemperatureupper Quaternaryvariationsurn:org.iodp:exp:166urnlargerWorkCitationcampaignurn:org.iodp:exp:166:site:1006urnlargerWorkCitationstudyurn:org.iodp:exp:166urnlargerWorkCitationcampaignEnglishgeoscientificInformation-79.2733-79.273324.235924.2359application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/166_SR/VOLUME/CHAPTERS/SR166_02.PDFdownload
