The Copernicus Marine Service
Convener: Stephanie Guinehut | Co-conveners: Anna Teruzzi, Julien Brajard, Andrea Storto, Benjamin JacobECSECS

The Copernicus Marine Service (previously known as the Copernicus Marine Environment Monitoring Service, CMEMS) provides regular and systematic reference information on the physical (including sea-ice and wind waves) and biogeochemical states of the global ocean and European regional seas. This capacity encompasses the description of the current ocean state (analysis and near-real time observations), the prediction of the ocean state a few days ahead (forecast), and the provision of consistent retrospective data records for recent decades (reanalyses and reprocessed observations). Copernicus Marine Service provides a sustainable response to private and public user needs, for academic, operational and private-sector activities and to support policies. The Copernicus Marine Service has started a new 7-yr phase covering 2021-2028.
The session focuses on the main Copernicus Marine Service activities on ocean modelling and coupling with other components of the climate system; data assimilation; processing of observations, impact and design of in-situ and satellite observing systems; verification, validation and uncertainty estimates of Copernicus Marine products; monitoring and long-term assessment of the ocean physical and biogeochemical states. Presentations dealing with the use and impact of Copernicus Marine products for downstream applications, including support to policies and directives, are also welcome.
Further, the session will encompass research activities that are required to maintain a state-of-the-art and user responsive Copernicus Marine Service and to prepare its long-term evolutions: extended range and ensemble ocean predictions, pan-European coastal zone monitoring, coupling with coastal systems and rivers, marine biology including higher trophic level modelling, Arctic ocean monitoring and forecasting and uptake of future Sentinel and other satellite missions, air/sea CO2 fluxes and carbon uptake, long-term regional ocean projections both for physics and biogeochemistry, digital oceans, big data and data science (AI, machine learning, etc).
Presentations are not limited to research teams directly involved in the Copernicus Marine Service and participation from external teams is strongly encouraged (e.g., from Horizon Europe projects relevant to Copernicus Marine and from downstream applications).
