The average global oceanic nitrogen deposition is 40.7&nbsp;Tg&nbsp;N&nbsp;yr<sup>−1</sup>, with 78% deposited in the open ocean. Reduced nitrogen (NH<sub>x</sub>) and oxidized nitrogen (NO<sub>y</sub>) contribute equally predominantly through wet deposition (62%). Of the total nitrogen deposition to oceans, 39% originates from natural emissions, 33% from fuel combustion including shipping and aviation (11%), and 22% from agricultural activities. Transportation and agriculture are the major contributors in the Northern Hemispheric mid-high latitude and Coastal biomes, whereas natural emissions are dominant in Trades and Southern Hemispheric biomes. Both wet and dry NO<sub>y</sub> deposition decreases in the Northern Hemisphere mid-high latitudes but increases in tropical biomes, whereas NH<sub>x</sub> shows opposing changes in wet and dry deposition. Anthropogenic emissions drive over 60% of IAVs of oceanic nitrogen deposition except for the NH<sub>x</sub> deposition over tropical biomes. Changes in anthropogenic emissions from combustion sources not only influence NO<sub>y</sub> deposition through nitrogen oxides (NO<sub>x</sub>) emissions from fuel combustions but also lead to opposing trends in wet and dry NH<sub>x</sub> deposition due to nonlinear chemistry of secondary inorganic aerosol formations. These findings highlight the need for integrated management strategies targeting multiple pollutants, including NO<sub>x</sub>, ammonia (NH<sub>3</sub>), and sulfur dioxide (SO<sub>2</sub>) along with international regulations on shipping and aviation to effectively control nitrogen deposition over the ocean.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Atmospheric reactive nitrogen deposition to the global ocean during the 2010s: Interannual variation and source attribution","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-29 01:31:52.564973","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-07-07","DateCreate":"2025-07-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1029/2024jd042789"},"refs":null,"anarec":{"AnaID":409678,"PubliDate":2025,"Pagination":"1-20","XtraPublOfAnaID":null,"ISBN":null,"Volume":"130","Issue":"8","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":272089,"SerRR":"Journal of Geophysical Research-Atmospheres.
