IOCCP in close collaboration with our global partners, continues to foster the integration of efforts around quality assurance for inorganic carbon measurements with the global metrology systems so that those measurements are metrologically traceable to the International System of Units.

We would like to inform you about the upcoming webinar on "Advancements in Biogeophysical 4D reconstructions: New methods development and exploitation of existing products for scientific investigations" organised by SCOR Working Group 168 (4D-BGC) on 26 November 2024, at 12:00 pm CET.

During the OA Week on 18-22 November, the ocean biogeochemistry community will have a great opportunity to discuss the most challenging issues around ocean acidification. This year we’d like to specifically encourage you to participate in a community discussion on “Building capacity in physical chemistry for oceanography: how to address the emerging skills gaps”.

We are happy to share that the call for abstracts for the One Ocean Science Congress is now open until 14 November 2024, 13:00 CET. The One Ocean Science Congress (OOSC), organised by CNRS and IFREMER, will be held in Nice, France, from 4 to 6 June 2025. It is a UN Special Event serving as the scientific foundation of the Third United Nations Ocean Conference (UNOC3).

We are excited to let you know that the Surface Ocean CO₂ Observing Network (SOCONET) alongside the Fishing Vessel Observing Network (FVON) and Science Monitoring And Reliable Telecommunications (SMART) Subsea Cables became a Global Ocean Observing System emerging network. Find out more on these 3 new additions from an article published on the GOOS website.

We are thrilled to let you know that the Global Greenhouse Gas Watch (G3W) Implementation Plan has been endorsed!

Thanks to the excellent work of the Joint Study Group on WMO Greenhouse Gas Monitoring (SG-GHG), the G3W Implementation Plan has been approved by INFCOM-3 (the WMO Technical Commission for Infrastructure) in April 2024, and by EC-78 (the Executive Council of WMO) in June 2024. We all owe a big Thank You to Adrienne Sutton (IOCCP SSG, NOAA, US) and Richard Sanders (IOCCP SSG, NORCE, Norway) for leading the writing of the Implementation Plan for the surface ocean CO2 (SOCONET and SOCAT). Other (SOCONET & SOCAT) contributors to the IP are Dorothee Bakker, Kevin O’Brien, Thanos Gkritzalis, Tobias Steinhoff, Bronte Tilbrook, Ronnie Noonan-Birch and Maciej Telszewski.

We are thrilled to announce the release of Surface Ocean CO₂ Atlas (SOCAT) version 2024 which is now available on SOCAT website. Since 2017 there has been a reduction in surface ocean CO₂ observations that is impacting our ability to quantify the ocean's role as a major sink for CO₂ emissions. The latest update of the community-led Surface Ocean CO₂ Atlas, version 2024, has delivered 38.6 million, quality-controlled, in situ surface ocean fCO2 (fugacity of CO2) measurements collected between 1957 and 2023 with an estimated accuracy of < 5 μatm.

We would like to Congratulate and Thank the whole SOCAT team as well as all data providers for their enormous continuous efforts related to annual releases of the product!

We are excited to let you know that IOCCP is looking for two new members to join its Scientific Steering Group (SSG) for terms beginning on 1 October 2024, to act as leaders responsible for maintaining and expanding IOCCP coordination activities around Nutrients and Nitrous Oxide EOVs.

Whether we aim to disentangle anthropogenic driven trends from natural variability or we want to assess and improve our ocean model’s capabilities to correctly display changes in time, all require high-quality observational data from multiple fixed time-series data. Until now access to these data was difficult, time-consuming, and often required solving multiple data challenges before these data were fit for the purpose. Following the successful examples set by well-known ocean synthesis products, the idea for SPOTS – the Synthesis Product for Ocean Time-Series – was born from this need to address these challenges.

We would like to share with you that IAPSO has selected three Best Practice Study Groups, one of which focuses on ‘Calibrating Measurements of Total Dissolved Inorganic Carbon in Seawater’. The main objectives of this Best Practice Study Group are to address the calibration strategies for commonly used instrumentation to measure total dissolved inorganic carbon (DIC) in seawater, write clear and detailed standard operating procedures (SOPs), assess the reliability and consistency among calibration methods, and suggest technological and commercial solutions to facilitate their implementation.
