A Collection of Surface Ocean CO₂ Observations
Quality Controlled by the Science Community
We will be organising a 24-hour SOCAT QC hackathon on 3rd February 2026. We invite old and new SOCAT data enthusiasts to join us for 24 hours of secondary quality control. Experienced data QCers will be on hand for the whole day, and every 4 hours we will have a short SOCAT QC presentation. Let’s get secondary QC done together!
More information about the hackathon will be available nearer the date.
SOCAT has published an update to the Quality Control Cookbook for use in SOCAT v2025. Download it here: SOCAT Cookbook for v2025.
SOCAT v2024 is released today, with 3.9 million new observations.

A poster summarising the key points of the release (including the continued decline in observation coverage) is available from: https://socat.info/wp-content/uploads/
The last week has seen the release of the Declaration on Operationalising the Surface Ocean Carbon Value Chain, also known as the Ostend Declaration, in which 100+ ocean experts and stakeholders call for concerted international and intergovernmental efforts to create a robust, resilient and sustainable surface ocean carbon observing system.
In 2023 the SOCAT community produced A Case for SOCAT laying out the cruicial role that SOCAT plays in understanding the ocean carbon cycle and therefore the Earth’s global carbon budgets.
SOCAT V2023 was released on the 20th of June 2023. For more information, please see the release poster.
The Flanders Marine Institute (Ostend, Belgium) will be hosting a wide-ranging workshop on the 6th-9th November to discuss many aspects of surface ocean pCO₂ observations and related topics. Full details can be found at the workshop webpage.
SOCAT V2022 was released on the 14th of June 2022. For more information, please see the release poster.
SOCAT V2021 was released on the 15th of June 2021. For more information, please see the release poster.
A new version of the SOCAT Quality Control Cookbook is available through the SOCAT Help page, under the Quality Control header. The new version applies for SOCAT version 7, and is an update to the cookbook for version 1 and 3.
