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.

 Application Closed!

To make inquiries and/or to submit your application, please contact the IOCCP Project Office (This email address is being protected from spambots.

Please share with your networks and potentially interested individuals.

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.

We would like to encourage you to consider submitting an abstract for the 1^st Stakeholder Meeting of the International Committee for Weights and Measures (CIPM) Sectorial Task Group on Climate Change and Environment (STG-CENV) to be held on 16-18 September 2024, in Sèvres, France.

We would like to let you know that the POGO-SCOR Fellowship programme for 2024 is now open for applications. This programme is jointly funded by the Partnership for Observation of the Global Ocean (POGO) and the Scientific Committee on Oceanic Research (SCOR). The deadline for applications is 30 April 2024 (23:59 CET).

We are very excited to inform you that the first edition of a global database of dissolved organic matter (CoastDOM v1) compiling previously published and unpublished concentration measurements in coastal waters is available from https://doi.org/10.1594/PANGAEA.964012. CoastDOM v1 includes measurements of DOC, DON and DOP concentrations from all continents between 1978 and 2022 and consists of 62 338, 20 356, and 13 533 datapoints respectively.

We would like to motivate you to consider nominating yourself or a colleague to serve as a Global Ocean Observing System Steering Committee member. The importance of such a role is outlined below, and we just want to add that our biogeochemistry community needs strong leadership on the GOOS SC in order to help inform the international and intergovernmental agendas on our needs and challenges related to fulfilling our roles as ocean and climate observers and analysts. Nominations and self-nominations of Early Career Ocean Professionals will be highly appreciated!

We are pleased to inform you that applications are now being accepted for this year's Dissertations Symposium in Chemical Oceanography (DISCO XXIX) to be held 19-24 October 2024 in Lihue, Kauaʻi, Hawaiʻi. This symposium is for recent graduates or soon to graduate PhD-level scientists working on chemical oceanography related topic, who are interested in pursuing a career in academia or research laboratories. The attendees will present their research in front of their professional peers and representatives from some of the federal agencies funding chemical oceanographic research, and have the opportunity to forge professional relationships that will facilitate their future research and academic careers.

We'd like to let you know that the SCOR Secretariat invites proposals for new working groups from now until 23:59 UTC on 17 May 2024. The guidelines, a template, and word limits are available at https://scor-int.org/work/groups/proposals/, including a PowerPoint presentation explaining the proposal process.
