Version 6 of the Surface Ocean CO2 Atlas (SOCAT) now available

The SOCAT website ( provides access to synthesis and gridded data products. Users can explore the data products via powerful, interactive online viewers, the Data Set Viewer and the Gridded Data Viewer. Alternatively, users can download of the synthesis and gridded products with Matlab code available for reading these files. An article in Earth System Science Data (ESSD) by Bakker et al. (2016) documents the data products and quality control criteria in SOCAT version 3, which also apply to versions 4 to 6. Users are kindly asked to follow the SOCAT Fair Data Use Statement by generously acknowledging the contribution of SOCAT scientists by invitation to co-authorship, especially for data providers in regional studies.

SOCAT scientific community has made a Voluntary Commitment of ‘Annual, public releases of the Surface Ocean CO2Atlas (SOCAT)’ to the UN Ocean Conference (#OceanAction20464). SOCAT enables quantification of the ocean carbon sink, ocean acidification, and evaluation of ocean biogeochemical models in a changing world. SOCAT represents a milestone in biogeochemical and climate research and in informing policy. However, SOCAT remains without sustained funding and as such, the effort is at risk.

Data submission for SOCAT version 7 ends 15 January 2019, while version 7 quality control ends 31 March 2019.
