An empirical orthogonal function (EOF) was used to derive the main drivers of spatial and temporal variability in the dataset. In open and coastal waters, drivers were identified as a biological component linked to riverine water, and temperature seasonality. Air-sea flux estimates indicate the GoM open (− 0.06 ± 0.45&nbsp;mol&nbsp;C&nbsp;m<sup>−2</sup>&nbsp;year<sup>−1</sup>) and coastal (− 0.03 ± 1.83&nbsp;mol C m<sup>−2</sup>&nbsp;year<sup>−1</sup>) ocean are approximately neutral in terms of an annual source or sink for atmospheric CO<sub>2</sub>. Surface water pCO<sub>2</sub> in the northwest and southeast GoM open ocean is increasing (1.63 ± 0.63&nbsp;µatm &nbsp;year<sup>−1</sup> and 1.70 ± 0.14&nbsp;µatm&nbsp;year<sup>−1</sup>, respectively) at rates comparable to those measured at long-term ocean time-series stations. The average annual increase in coastal CO<sub>2</sub> was 3.20 ± 1.47 µatm year<sup>-1</sup> for the northwestern GoM and 2.35 ± 0.82&nbsp;µatm&nbsp;year<sup>−1</sup> for the west Florida Shelf. However, surface CO<sub>2</sub> in the central (coastal and open) GoM, which is influenced by Mississippi and Atchafalaya River outflow, remained fairly stable over this time period.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Surface water CO<sub>2</sub> variability in the Gulf of Mexico (1996–2017)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-11 01:32:40.290470","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2020-08-18","DateCreate":"2020-08-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000556698500031","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41598-020-68924-0"},"refs":null,"anarec":{"AnaID":328081,"PubliDate":2020,"Pagination":"13 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"10","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
