Samples were analyzed following GEOTRACES methods and compared to previous results from 1991. We observe significant decreases in <sup>230</sup>Th concentrations in the deep waters of the Nansen Basin. We ascribe this nonsteady state removal process to a variable release and scavenging of trace metals near an ultraslow spreading ridge. This finding demonstrates that hydrothermal scavenging in the deep‐sea may vary on annual time scales and highlights the importance of repeated GEOTRACES sections.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Importance of hydrothermal vents in scavenging removal of <sup>230</sup>Th in the Nansen Basin","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-09 01:31:59.815675","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Geotraces; <sup>230</sup>Th time series; hydrothermal vents; <sup>230</sup>Th scavenging removal; Arctic Ocean; Gakkel Ridge","OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2022-10-11","DateCreate":"2018-12-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000448656800058","VABBcode":null,"OpenAcc":1,"DOI":"10.1029/2018GL079829"},"refs":null,"anarec":{"AnaID":303665,"PubliDate":2018,"Pagination":"10,539-10,548","XtraPublOfAnaID":null,"ISBN":null,"Volume":"45","Issue":"19","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42920,"SerRR":"Geophysical Research Letters.
