In contrast, in the Subantarctic Zone, export production increased into ice ages coinciding with rising dust fluxes, thus suggesting iron fertilization of subantarctic phytoplankton. Here, a new high-resolution productivity record from the Antarctic Zone is compiled with parallel subantarctic data over the past million years. Together, they fit the view that the combination of these two modes of Southern Ocean change determines the temporal structure of the glacial-interglacial atmospheric CO2 record, including during the interval of \"lukewarm\" interglacials between 450 and 800 thousand years ago.","pubRank":"1"}],"site":[{"NOAASiteId":"19271","siteName":"ODP 1094","siteCode":null,"mappable":"Y","locationName":"Ocean>Atlantic Ocean>South Atlantic Ocean","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["-53.18035","5.130333"]},"properties":{"southernmostLatitude":"-53.18035","northernmostLatitude":"-53.18035","westernmostLongitude":"5.130333","easternmostLongitude":"5.130333","minElevationMeters":"-2807","maxElevationMeters":"-2807"}},"paleoData":[{"dataTableName":"ODP1094-TN57-13PC-MAR","NOAADataTableId":"24295","earliestYear":155020,"mostRecentYear":1460,"timeUnit":"cal yr BP","earliestYearBP":155020,"mostRecentYearBP":1460,"earliestYearCE":-153070,"mostRecentYearCE":490,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/contributions_by_author/jaccard2013/jaccard2013-230Th-MAR.txt","urlDescription":"NOAA Template File","linkText":"ODP 1094 Accumulation Rate Data","variables":[{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"sampling metadata>notes","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"core information","cvFormat":"Character","cvShortName":"notes"},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>element or single-element molecule>chlorine","cvMaterial":"geological material>bulk geological material>sediment","cvError":null,"cvUnit":"rate unit>mass per area per time unit>microgram per square centimeter per kiloyear","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"mass accumulation rate","cvFormat":"Numeric","cvShortName":"chlorMAR"},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>element or single-element molecule>barium","cvMaterial":"geological material>bulk geological material>sediment","cvError":null,"cvUnit":"rate unit>mass per area per time unit>milligram per square centimeter per kiloyear","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"biogenic barium;
