We are very excited to share the first part of ObsSea4Clim Essential Ocean Variables (EOV) Reliability, Accuracy, and Uncertainty Maps (V.1) in our newest deliverable D2.1.

The EOV Reliability, Accuracy, and Uncertainty Maps (V.1) focus on assessing in situ data availability and uncertainties for key parameters like temperature, salinity, and currents, which are crucial for understanding ocean dynamics.

Why is it needed?

• EOVs are fundamental for monitoring ocean changes, thus supporting climate research, ecosystem management, and ocean forecasting and warning.
• Despite advances in data collection of ocean physics, there are still challenges related to e.g. incomplete datasets, inadequate metadata documentation, and varying quality control.

Using tools like EMODnet Physics, our team at ObsSea4Clim has begun mapping data density and uncertainties to pinpoint gaps and improve data transparency and accessibility.
These efforts aim to enhance the FAIR (Findable, Accessible, Interoperable, Reusable) provision of EOVs, ensuring broader usability for stakeholders and improving the reliability of ocean analysis.

This work is part of a broader dialogue with data providers to recommend improvements in metadata quality and data integration, ultimately strengthening marine research globally.

We encourage everyone to follow us on LinkedIn and stay tuned for updates as we continue refining this tool and expanding its applications.

Congratulations and thank you for an excellent work on this deliverable to Beatrice Maddalena Scotto, Antonio Novellino and ETT S.p.A. team and all contributors!
