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.

REPROSEED, « REsearch to improve PROduction of SEED » is a European project conducted by partners from several countries that aim to promote the development of the mollusc aquaculture such as Spain, Portugal, France and Norway. Mollusc farming is important as this industry is expected to contribute significantly to the European economy in the coming years. REPROSEED (http://www.reproseed.eu/) give a list of European hatcheries. EUROSHELL offers a map of that list.

The Coastal Zones LC/LU Change (CZC) 2012-2018 is providing the Land Cover / Land Use (LC/ LU) change for areas along the coastline of the EEA38 countries and the United Kingdom, between the reference years 2012 and 2018. The Coastal Zones 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 Change product covers a buffer zone of coastline derived from EU-Hydro v1.1. The Land Cover/Land Use (LC/LU) Change layer is extracted from Very High Resolution (VHR) satellite data and other available data. The reference years for the change are 2012 and 2018. 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 status product is available for the 2012 and 2018 reference years. This CZC dataset is distributed in vector format, in a single OGC GeoPackage file covering the area of interest.
