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 2025, to act as leaders responsible for Coordination of Optimal Global Design for Ocean Carbon Observations (Position #1) and Coordination of Regional Ocean Biogeochemical Observations in Latin America (Position #2).

We are excited to share with you an important document describing the first operational steps to implement the reference-quality measurements of the Surface Ocean CO₂ Observing Network (SOCONET-Tier 1). SOCONET-Tier 1 is the observational cornerstone for surface ocean fCO₂w observations to quantify sea-air CO₂ fluxes with sustained delivery of reference quality datasets in support of efforts such as the Global Carbon Budget, Global Greenhouse Gas Watch and other assessments and activities.

We are thrilled to inform you that the Surface Ocean CO₂ Atlas (SOCAT) version 2025 is now available on the SOCAT website. We would like to congratulate and thank the entire SOCAT team, as well as all data providers, for their enormous continuous efforts related to annual releases of the product.

We would like to share with you the Call for Review of 2025 SCOR Working Group Proposals sent to SCOR National Committees and Nominated Members, SCOR Executive Committee, Chairs of SCOR Subsidiary Bodies, Affiliated Organizations, Corresponding Organizations, Interested International Organizations.

In our continuous efforts to optimise and operationalise ocean carbon observations we would like to invite you to attend the UN Ocean Decade Conference 2025 off-site side event From Science to Solutions: Advancing the Ocean Carbon System for Climate Action hosted by ICOS, JPI Oceans & Ocean Frontier Institute with support from GEOMAR, NOC, Ifremer, NORCE, and IOPAN.

We would like to kindly remind you that the application for the OceanObs’29 Program Committee deadline is approaching on 31 May 2025.

We are excited to announce that the Oostende Declaration in which the 100+ ocean experts and stakeholders call for concerted international and intergovernmental efforts to create a robust, resilient and sustainable surface ocean carbon observing system has been officially recognized as a commitment at the UN Ocean Conference 2025.

We would like to inform you that an international data workshop on the role of biology in storing carbon in the ocean has been announced. This workshop is organised as part of the UK NERC BIO-Carbon research programme, with the support of the Marine Biogeochemistry Forum from the Marine Alliance for Science and Technology for Scotland (MASTS). The workshop is planned to take place on 2-4 March 2026 in Glasgow (UK), immediately after Ocean Sciences 2026.

The workshop will bring together scientists from around the world, to pool data on key processes and to determine how we should go about capturing those processes in the next generation of climate models. A major aim of the workshop is to bring modellers, observationalists and experimentalists together to co-design roadmaps for how this should happen.

We are pleased to share that the POGO-SCOR Fellowship Programme for 2025 is now open for applications. The deadline for applications is 27 April 2025 (23:59 CET).

The primary goal of the POGO-SCOR Fellowship Programme is to strengthen sustained ocean observations and their applications, with a focus on training and capacity building to support a global ocean observation framework. Since its launch in 2001, the programme has been highly successful, awarding 200 fellowships to date.

We wanted to share an exciting news that an open-access book Chemical Reference Materials for Oceanography: History, Production, and Certification has now been published in the Springer Oceanography book series.

The book explores the history, production, and certification of reference materials for essential parameters in oceanography and provides a comprehensive understanding of them to readers.
