The European Atlas of the Seas provides information about Europe’s marine environment. Users can view predefined and ready to use maps, covering topics such as nature, tourism, security, energy, passenger transport, sea bottom, fishing stocks and quotas, aquaculture, and much more. Users can also benefit from an enriched catalogue with more than 200 map layers, covering a wide range of topics, to explore, collate and create their own maps. These maps can be printed, shared and embedded in articles or presentations. The Atlas is the ideal tool for schools, researchers and professionals, or anyone wishing to know more about the European seas and its coastal areas.
