IMMERSE is a research project which aims to prepare numerical ocean models for the next generation Copernicus Marine Environment Monitoring Service (CMEMS). We intend to develop new capabilities in order to:

  • enable the production of ocean forecasts and analyses that exploit upcoming high resolution satellite datasets;
  • deliver ocean analyses and forecasts with the higher spatial resolution and additional process complexity demanded by users;
  • exploit the opportunities of new high performance computing technology;
  • allow easy interfacing of CMEMS products with detailed local coastal models.

These developments are delivered in the NEMO ocean model, an established, world-class ocean modelling system that already forms the basis of the majority of the Copernicus Marine Environment Monitoring Service analysis and forecast products.


The IMMERSE consortium combines expertise in ocean modelling, applied mathematics, high performance computing, software engineering, and in-depth knowledge of the CMEMS systems and downstream CMEMS systems.

After 30 months of efforts and a global pandemics, the IMMERSE project team and the NEMO system team are glad to officially announce the beta-release of NEMO version 4.2 almost on time ! Congratulations to all the NEMO developpers for this major contribution to the evolution of CMEMS services.


The need for setting up a new forum for NEMO users to share experience and tips was raised during one of the splinter sessions of our general assembly in March 2021. In response to this need, the NEMO system team opened a new forum on discourse a week ago. Open 7 days ago the forum has already 57 registered users ! Thanks to the NEMO system team for its reactivity !


The IMMERSE consortium has organized a session dedicated to the numerical modelling of ocean circulation jointly supported by the NEMO consortium at vEGU2021. Several of the new developments to NEMO supported by IMMERSE have been presented during this vibrant session. We are now all looking foreward to meet again in person next year !


The project general assembly was held virtually on March 3-5. About 80 participants and key stakeholder have registered to our plenary sessions and splinter discussions. A great time for us to take stock of the project progress and refine our plans for the coming months.


The project General Assembly was held in Paris on 12-13 Dec 2019. We decided to gather at the same location and time as the NEMO System Team for its annual merge party. The first two years of the IMMERSE project indeed mostly consist in developments to the NEMO ocean model and this is why we articulate our agenda and activities with the NEMO consortium. The meeting consisted in a combination of talks reviewing the project progress and more in depth scientific presentations.


On April 5th 2019, the IMMERSE Users Remote Workshop was held to introduce the IMMERSE interfaces to the CMEMS users community and coastal modellers, outside the project. The webinar was organized by CMCC Foundation and NOC. After a brief introduction to present the IMMERSE project and the Task 7.3 by Dorotea Iovino (CMCC), Yann Drillet from Mercator Ocean presented CMEMS and its main actions on Marine Services & System Evolutions, and the structure of DIAS « WekEO ».


IMMERSE project was officially launched on 24 and 25 January 2019 in Grenoble during the kick-off meeting with fourteen project partners. This kick-off meeting was an opportunity for the consortium to discuss the project methodology, the different activities to be implemented and the upcoming deadlines.
