We investigated WAO N<sub>2</sub>O dynamics through an intensive and precise N<sub>2</sub>O survey during the open-water season of summer 2017. The effects of physical processes (i.e., solubility and advection) were dominant in both the surface (0–50&nbsp;m) and deep layers (200–2200&nbsp;m) of the northern Chukchi Sea with an under-saturation of N<sub>2</sub>O. By contrast, both the surface layer (0–50&nbsp;m) of the southern Chukchi Sea and the intermediate (50–200&nbsp;m) layer of the northern Chukchi Sea were significantly influenced by biogeochemically derived N<sub>2</sub>O production (i.e., through nitrification), with N<sub>2</sub>O over-saturation. During summer 2017, the southern region acted as a source of atmospheric N<sub>2</sub>O (mean: + 2.3 ± 2.7&nbsp;μmol N<sub>2</sub>O m<sup>−2</sup> day<sup>−1</sup>), whereas the northern region acted as a sink (mean −&nbsp;1.3 ± 1.5&nbsp;μmol N<sub>2</sub>O m<sup>−2</sup> day<sup>−1</sup>). If Arctic environmental changes continue to accelerate and consequently drive the productivity of the Arctic Ocean, the WAO may become a N<sub>2</sub>O “hot spot”, and therefore, a key region requiring continued observations to both understand N<sub>2</sub>O dynamics and possibly predict their future changes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"N<sub>2</sub>O dynamics in the western Arctic Ocean during the summer of 2017","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-08 01:31:23.956777","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-06-16","DateCreate":"2021-06-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000664660600021","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41598-021-92009-1"},"refs":null,"anarec":{"AnaID":339094,"PubliDate":2021,"Pagination":"12589","XtraPublOfAnaID":null,"ISBN":null,"Volume":"11","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
