The Coastal Zones (CZ) LC/LU product for 2018 is providing a detailed Land Cover / Land Use (LC/ LU) dataset for areas along the coastline of the EEA38 countries and the United Kingdom, with reference year 2018 for the classification. This product monitors landscape dynamics in European coastal territory to an inland depth of 10 km with a total area of approximately 730,000 km², with all the relevant areas (estuaries, coastal lowlands, nature reserves). The production of the coastal zone layers was coordinated by the European Environment Agency (EEA) in the frame of the EU Copernicus programme, as part of the Copernicus Land Monitoring Service (CLMS) Local Component. The Coastal Zones product covers a buffer zone of coastline derived from EU-Hydro v1.1. Land Cover/Land Use (LC/LU) layer is extracted from Very High Resolution (VHR) satellite data and other available data. The class definitions follow the pre-defined nomenclature on the basis of Mapping and Assessment of Ecosystems and their Services (MAES) typology of ecosystems (Level 1 to Level 4) and CORINE Land Cover adapted to the specific characteristics of coastal zones. The classification provides 71 distinct thematic classes with a Minimum Mapping Unit (MMU) of 0.5 ha and a Minimum Mapping Width (MMW) of 10 m. The product is available for the 2012 and 2018 reference year including change mapping. This CZ dataset is distributed in vector format, in a single OGC GeoPackage SQLite file covering the area of interest.

Raw siescan sonar data archived at SISMER, acquired: - by oceanographic vessels and national equipment managed by the French Oceanographic Fleet (FOF) - by foreign oceanographic vessels in collaboration with Ifremer - by Ifremer's historic vessels (Jean Charcot, Nadir, Suroit) operated before the FOF was set up

Raw multibeam from acoustic echosounding of the water column and archived at SISMER. These data have been acquired: - by oceanographic vessels and national equipment managed by the French Oceanographic Fleet (FOF) - by foreign or national oceanographic vessels in collaboration with Ifremer

The analysis focuses on monitoring the ecological status of the coastal and transitional waters of the Western Channel and the Bay of Biscay. The ecological status of a coastal water body within the meaning of the European Water Framework Directive (WFD) is determined by the biological state, physicochemical state and hydromorphological state of the water mass, water. The statement is determined according to the rules described in the decree of 25 January 2010.
