The Surface Ocean CO\u2082 Atlas (SOCAT)\u00a0is a synthesis activity for quality-controlled, surface ocean fCO\u2082 (fugacity of carbon dioxide) observations by the international marine carbon research community (>100 contributors).\u00a0SOCAT data is publicly available, discoverable and citable. SOCAT enables quantification of the ocean carbon sink and ocean acidification and evaluation of ocean biogeochemical models. SOCAT, which celebrated its 10th anniversary in 2017, represents a milestone in biogeochemical and climate research and in informing policy.<\/p>\n
SOCAT data are released in versions. Each succeeding version contains new data sets as well as updates of older ones. The first version of SOCAT was released in 2011, the second and third version followed biennially. Automation allowed annual public releases since version 4. The latest SOCAT version (version 2025) has 41.4 million observations from 1957 to 2023 with an estimated accuracy of <\u00b15 \u00b5atm for the global oceans and coastal seas. 8.2 million calibrated sensor observations (with estimated accuracy of \u00b15-10 \u00b5atm) are also available.\n\nSOCAT version 2025 was released on the 5th of June 2025, containing data submitted on or before 15th of January 2025. New data submissions are welcome at any time, and will be included in the next SOCAT release. The submission<\/a> deadline for v2026 is 15 January 2026.<\/p>\n SOCAT is a core Global Ocean Observing System data product for biogeochemistry endorsed by the Global Ocean Observing System GOOS<\/a>.<\/p>\n The Surface Ocean CO\u2082 Atlas (SOCAT)\u00a0is a synthesis activity for quality-controlled, surface ocean fCO\u2082 (fugacity of carbon dioxide) observations by the international marine carbon research community (>100 contributors).\u00a0SOCAT data is publicly available, discoverable and citable.
