MeshAtlantic promoted harmonised production and use of marine habitat maps covering the Atlantic Area. To reach this goal, it adapted and enhanced previous achievements to the area, hence bringing the region onto equal footing with northern Europe. The key outputs of the project were three different sets of maps made homogeneous across the area in the Eunis nature classification. By building and acquiring this knowledge, MeshAtlantic intended to serve the community at large. Based on a multi-faceted communication plan, the project was carried out in close collaboration with marine environment users, among them fishermen, conservationists and managers who act for sustainable use of marine space and resources.
