We would like to encourage you to participate in an exciting webinar series exploring how data sharing software is transforming marine science. This online event is scheduled for October and November 2025 and is organised by the Decade Coordination Office for Ocean Data Sharing (DCO-ODS) and the European Marine Observation and Data Network (EMODnet).

We would like to inform you that we are extending the deadline for applications for two new members to join the IOCCP Scientific Steering Group (SSG) 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.
