However, the geographical distribution and controlling factors of marine N<SUB>2</SUB> fixation remain elusive largely due to sparse observations. Here we present unprecedented high-resolution underway N<SUB>2</SUB> fixation estimates across over 6000 kilometers of the western North Atlantic. Unexpectedly, we find increasing N<SUB>2</SUB> fixation rates from the oligotrophic Sargasso Sea to North America coastal waters, driven primarily by cyanobacterial diazotrophs. N<SUB>2</SUB> fixation is best correlated to phosphorus availability and chlorophyll-a concentration. Globally, intense N<SUB>2</SUB> fixation activity in the coastal oceans is validated by a meta-analysis of published observations and we estimate the annual coastal N<SUB>2</SUB> fixation flux to be 16.7 Tg N. This study broadens the biogeography of N<SUB>2</SUB> fixation, highlights the interplay of regulating factors, and reveals thriving diazotrophic communities in coastal waters with potential significance to the global nitrogen and carbon cycles.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Revisiting the distribution of oceanic N<sub>2</sub> fixation and estimating diazotrophic contribution to marine production","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-04 01:31:31.463988","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2019,"MonPub":null,"DateUpdate":"2021-05-17","DateCreate":"2019-02-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000459055400005","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41467-019-08640-0"},"refs":null,"anarec":{"AnaID":306491,"PubliDate":2019,"Pagination":"10 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"10","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":198717,"SerRR":"Nature Communications.
