We characterized an exponential response in N2O production to decreasing oxygen between 1 and 30 mu mol O-2 l(-1) within and below the oxycline using (NO2-)-N-15, a relationship that held along a 550 km offshore transect in the North Pacific. Differences in the overall magnitude of N2O production were accounted for by archaeal functional gene abundance. A one-dimensional (1D) model, parameterized with our experimentally derived exponential terms, accurately reproduces N2O profiles in the top 350m of water column and, together with a strong (N2O)-N-45 signature indicated neither canonical nor nitrifier-denitrification production while statistical modelling supported production by archaea, possibly via hybrid N2O formation. Further, with just archaeal N2O production, we could balance high-resolution estimates of sea-to-air N2O exchange. Hence, a significant source of N2O, previously described as leakage from bacterial ammonium oxidation, is better described by low-oxygen archaeal production at the oxygen minimum zone's margins.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Nitrous oxide as a function of oxygen and archaeal gene abundance in the North Pacific","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:32:57.722823","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":"2016-12-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000389495200001","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/ncomms13451"},"refs":null,"anarec":{"AnaID":281756,"PubliDate":2016,"Pagination":"10 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"13451","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":198717,"SerRR":"Nature Communications.
