Existing evidence supports an increase in U-234/U-238 since the last glacial period, but the timing and amplitude of its variability has been poorly constrained. Here we report two seawater U-234/U-238 records based on well-preserved deep-sea corals from the low-latitude Atlantic and Pacific Oceans. The Atlantic U-234/U-238 started to increase before major sea-level rise and overshot the modern value by 3 per mil during the early deglaciation. Deglacial U-234/U-238 in the Pacific converged with that in the Atlantic after the abrupt resumption of Atlantic meridional overturning. We suggest that ocean mixing and early deglacial release of excess U-234 from enhanced subglacial melting of the Northern Hemisphere ice sheets have driven the observed U-234/U-238 evolution.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Ocean mixing and ice-sheet control of seawater <sup>234</sup>U/<sup>238</sup>U during the last deglaciation","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-13 01:31:30.542000","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2016-11-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000386869800051","VABBcode":null,"OpenAcc":0,"DOI":"10.1126/science.aag1015"},"refs":null,"anarec":{"AnaID":281394,"PubliDate":2016,"Pagination":"626-629","XtraPublOfAnaID":null,"ISBN":null,"Volume":"354","Issue":"6312","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43776,"SerRR":"Science (Washington).
