Data & products on marine water quality

Dear User, the EMODnet Chemistry portal will soon be integrated into our new EMODnet Central Portal, which will provide continued, open and free access to our data and information services with unique new features. By providing a Centralised EMODnet service, we aim to help you optimise your research and work.

You can preview our new unified content, document search facilities and unified data catalogue via the EMODnet Product Catalogue.

The new and optimised common map viewer will be launched in November 2022.

Follow us on Twitter @EMODnet for the latest news on our centralisation process and new features.

For any questions or comments, you can contact us here.


EMODnet Chemistry started in 2009, based on a step by step approach. In 2021, the participants signed the fifth phase in force until 2023.

The portal development is made up of the following phases:

The pilot phase, from June 2009 to June 2012, was aimed at testing the project feasibility in limited geographical areas on a restricted number of parameters.

The second phase, from August 2013 to August 2016, was aimed at expanding spatial coverage and range of chemical parameters.

The third phase, from March 2017 to March 2019, was aimed at extending the data focus, including Marine Litter data and data products, and the spatial coverage.

The fourth phase, from October 2019 to October 2021, was aimed at gathering and managing new marine litter types and increasing engagements and cooperations.

The fifth phase, from October 2021 to October 2023, is beig led by the same core group of the Consortium steering the initiative since the beginning.

Detailed technical information on the latest phases can be found under Reports to EU.
