The Surface Ocean CO2 Atlas (SOCAT)

Version 5

The Surface Ocean CO2 Atlas (SOCAT) is a synthesis activity for quality-controlled, surface ocean fCO2 (fugacity of carbon dioxide) observations by the international marine carbon research community (>100 contributors). SOCAT 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 celebrates its 10th anniversary in 2017, represents a milestone in biogeochemical and climate research and in informing policy.

Acknowledgements:

‘The Surface Ocean CO2 Atlas (SOCAT) is an international effort, endorsed by the International Ocean Carbon Coordination Project (IOCCP), the Surface Ocean Lower Atmosphere Study (SOLAS) and the Integrated Marine Biosphere Research (IMBeR) program, to deliver a uniformly quality-controlled surface ocean CO2 database. The many researchers and funding agencies responsible for the collection of data and quality control are thanked for their contributions to SOCAT.’ Report problems to submit@socat.info and inform submit@socat.info of publications in which SOCAT is used. Please, contact the SOCAT investigators for further advice.
