Dissolved inorganic carbon (DIC) and total alkalinity (TA) increased with salinity. DIC and TA were generally conservative in the estuarine mixing zone (salinity &gt; 10), while a complex distribution pattern was observed at the upper estuary. DIC values peaked 1786.9 ± 155.8 µmol kg<sup>−1</sup> at that segment. Estimated annual mean fluxes of DIC were 0.27 Tg C yr<sup>−1</sup> from the river to the estuary, and 0.37 Tg C yr<sup>−1</sup> from here to the coastal area. The Tagus estuary was always CO<sub>2</sub> supersaturated, with partial pressure of CO<sub>2</sub> (<i>p</i>CO<sub>2</sub>) reaching 9160 µatm in the upper estuary. An average emission of 0.11 Tg C yr<sup>−1</sup> was estimated from the estuary to the atmosphere, corresponding to 23% of exported DIC. Only 8% of the riverine DIC was ventilated. The non-conservative behaviour of CO<sub>2</sub> parameters in the estuary segment under freshwater influence was attributed to alternations in the relevance of riverine/terrestrial runoff, photosynthesis, aerobic respiration, organic matter mineralization and CaCO<sub>3</sub> precipitation/dissolution.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Inorganic carbon distribution and CO<sub>2</sub> fluxes in a large European estuary (Tagus, Portugal)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:41.221639","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-09-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000407080100006","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41598-017-06758-z"},"refs":null,"anarec":{"AnaID":288969,"PubliDate":2017,"Pagination":"14 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
