    The Map of the Week shows the near real time daily Chlorophyll-a concentration at the ocean surface in regions which were not covered by clouds. Chlorophyll-a is a proxy for the abundance of photosynthetic plankton, the primary producers of the ocean.

    On 29 September 2021, the European Commission launched five new European Union (EU) Missions which aim to tackle big challenges in health, climate and the environment, and to achieve ambitious and inspiring goals in these areas. These five EU Missions address the following topics: Adaptation to Climate Change, Cancer, Restore our Ocean and Waters by 2030, 100 Climate-Neutral and Smart Cities by 2030 and A Soil Deal for Europe. The following actions are included under the Ocean and Waters Mission [1]:

    • The Horizon Europe programme will provide EUR 344.16 million in the period 2021-23 to support the implementation of the Mission, with other funding including from the European Maritime Fisheries and Aquaculture Fund, Invest EU and other programmes;
    • Launch of ‘lighthouses’ in major sea and river basins to pilot, demonstrate and deploy solutions to achieve the Mission objectives;
    • Conclusion of lighthouse implementation charters to ensure governance and political commitment;
    • Establishisment of EU-wide ‘Blue Parks’ to provide new restoration and conservation opportunities, as well as expand networks of marine protected areas;
    • Put in place a digital ocean and water knowledge system which includes preparation of the Digital Twin Ocean, an action contributing to the activities of the Destination Earth Initiative, and improved environmental monitoring of ocean health, supporting effective water management;
    • Connect, mobilize and empower European citizens and local communities to take action for the restoration of the ocean and waters in a more inclusive way.

    The Communication from the Commission on European Missions points out that the Ocean and Waters Mission will  for example pilot  and  test  ground-breaking  research  and  innovation  to  map,  monitor,  predict,  manage  and  restore  the ocean  and  waters  under  adverse  climate  change  and  anthropogenic pressures. It indicates that the Mission will build on and extend existing and planned European infrastructures and  services  such  as  Copernicus  and the European Marine Observation and Data Network (EMODnet).

    The data presented in many map layers in the European Atlas of the Seas are provided by EMODnet as can be seen from the Atlas overview.  Copernicus Marine Service is also the data provider of several maps on global mean sea level regional trend, global sea surface temperature regional trend and global ocean chlorophyll. Chlorophyll-a is a pigment produced by many organisms for realising photosynthesis. Ocean surface chlorophyll is measured by satellites and is a proxy for ocean productivity. [2] The Map of the Week shows daily global surface ocean chlorophyll-a concentration. This product is derived from multiple optical satellite sensors (SeaWiFS, MODIS-Aqua, MERIS, VIIRSN and OLCI-S3A) and calculated using the Copernicus GlobColour processor.
