However, the present ocean delta C-13 distribution is strongly overprinted by isotopically light anthropogenic carbon dioxide. A correction for this oceanic C-13 Suess effect in the North Atlantic (NA) shows that the pristine NA delta C-13 distribution has a richer and more detailed structure that is more clearly related to water mass distributions. Our results revise some fundamental perceptions regarding glacial-interglacial ocean delta C-13 differences and allow paleo-delta C-13 variations to be understood within the context of modern climate variability.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Large d<sup>13</sup>C gradients in the preindustrial North Atlantic revealed","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-24 01:31:15.383806","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2010,"MonPub":null,"DateUpdate":"2018-02-15","DateCreate":"2010-11-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000283580600044","VABBcode":null,"OpenAcc":0,"DOI":"10.1126/science.1193769"},"refs":null,"anarec":{"AnaID":200037,"PubliDate":2010,"Pagination":"658-659","XtraPublOfAnaID":null,"ISBN":null,"Volume":"330","Issue":"6004","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43776,"SerRR":"Science (Washington).
