Une masse d'eau côtière est une partie distincte et significative des eaux de surface situées entre la ligne de base servant pour la mesure de la largeur des eaux territoriales et une distance d’un mille marin. Correspondance rapportage DCE : cette entité correspond au concept de Coastal Water Body (CWBODY) de WISE.. Elle permet de définir les objectifs environnementaux, d’évaluer l’état des milieux et ultérieurement de vérifier l’atteinte de ces objectifs. La version diffusée sur le site du SANDRE est conforme au rapportage de 2016 . La prochaine version du référentiel Masse d’eau (masses d’eau provisoires, définies pour l’Etat des Lieux) est prévu pour 2019. Les couches sont diffusées dans un format conforme au dictionnaire de données SANDRE du Référentiel masse d’eau, version 1.3.

The bathing water quality data services include all coastal and inland bathing waters reported and assessed in the European Union Member States, Albania, Switzerland and the United Kingdom. The data is reported annually in the scope of the Bathing Water Directive (Directive 2006/7/EC of the European Parliament and of the Council of 15 February 2006, BWD) reporting obligations. The map services in https://water.discomap.eea.europa.eu/arcgis/rest/services/BathingWater show the location of the bathing waters and the assessment of bathing water quality for the last reported bathing season, as well as for the ten previous bathing seasons. Each bathing water is assessed for three statuses: 1) monitoring calendar status, 2) management status, 3) bathing water quality status. The monitoring calendar status evaluates the implementation of the monitoring calendar in the last reported season (as defined in Annex IV of the Bathing Water Directive). The management status evaluates the management in the last assessment period, whether the bathing water was continuously monitored or not. The bathing quality status evaluates the quality of bathing waters according to the two microbiological parameters: Escherichia coli and Intestinal enterococci (as defined in Annexes I and II of the Bathing Water Directive). The bathing water quality is classified in one of four classes: “Excellent”, “Good”, “Sufficient” or “Poor”. The status “Not classified” is applied if there are not enough available samples to evaluate the water quality. The data service in https://discodata.eea.europa.eu/ contains the results of the bathing water status since 1990: [WISE_BWD].[latest].[assessment_BathingWaterStatus] It also contains the reported data in the following tables: [WISE_BWD].[latest].[timeseries_Characterisation] [WISE_BWD].[latest].[timeseries_SeasonalPeriod] [WISE_BWD].[latest].[timeseries_MonitoringResult] [WISE_BWD].[latest].[spatial_SpatialProtected]

The service contains information about the ecological status or potential of European surface water bodies, delineated for the 2nd River Basin Management Plans (RBMP) under the Water Framework Directive (WFD). The Quality Element status is the poorest of the known quality element status values per water body. For example, the nutrient conditions status (QE3-1-6) is based on the following two quality elements: Nitrogen conditions (QE3-1-6-1) and Phosphorus conditions (QE3-1-6-2). The ecological status or potential is presented for the following quality elements: QE1 - Biological quality elements; QE1-1 - Phytoplankton; QE1-2 - Other aquatic flora; QE1-2-1 - Macroalgae; QE1-2-2 - Angiosperms; QE1-2-3 - Macrophytes; QE1-2-4 - Phytobenthos; QE1-3 - Benthic invertebrates; QE1-4 - Fish; QE2 - Hydromorphological quality elements; QE2-1 - Hydrological or tidal regime; QE2-2 - River continuity conditions; QE2-3 - Morphological conditions; QE3 - Chemical and physico-chemical quality elements; QE3-1 - General parameters; QE3-1-1 - Transparency conditions; QE3-1-2 - Thermal conditions; QE3-1-3 - Oxygenation conditions; QE3-1-4 - Salinity conditions; QE3-1-5 - Acidification status; QE3-1-6 - Nutrient conditions; QE3-1-6-1 - Nitrogen conditions; QE3-1-6-2 - Phosphorus conditions; QE3-3 - River Basin Specific Pollutants. The information was reported to the European Commission under the Water Framework Directive (WFD) reporting obligations. The dataset compiles the available spatial data related to the 2nd RBMPs due in 2016 (hereafter WFD2016). See http://rod.eionet.europa.eu/obligations/715 for further information on the WFD2016 reporting. Relevant concepts: Surface water body: Body of surface water means a discrete and significant element of surface water such as a lake, a reservoir, a stream, river or canal, part of a stream, river or canal, a transitional water or a stretch of coastal water. Surface water: Inland waters, except groundwater; transitional waters and coastal waters, except in respect of chemical status for which it shall also include territorial waters. Inland water: All standing or flowing water on the surface of the land, and all groundwater on the landward side of the baseline from which the breadth of territorial waters is measured. River: Body of inland water flowing for the most part on the surface of the land but which may flow underground for part of its course. Lake: Body of standing inland surface water. Transitional waters: Bodies of surface water in the vicinity of river mouths which are partly saline in character as a result of their proximity to coastal waters but which are substantially influenced by freshwater flows. Coastal water: Surface water on the landward side of a line, every point of which is at a distance of one nautical mile on the seaward side from the nearest point of the baseline from which the breadth of territorial waters is measured, extending where appropriate up to the outer limit of transitional waters.

Les zones de production conchylicole sont identifiées au titre du paquet européen hygiène (CE/854/2004) et de l'arrêté du 21 mai 1999 relatif au classement de salubrité et à la surveillance des zones de production et des zones de reparcage des coquillages vivants. L'ensemble des zones de production de coquillages (zones d’élevage et de pêche professionnelle) fait ainsi l’objet d’un classement sanitaire, défini par arrêté préfectoral. Celui-ci est établi sur la base d’analyses des coquillages présents : analyses microbiologiques utilisant Escherichia coli (E. coli) comme indicateur de contamination (en nombre d’E. coli pour 100 g de chair et de liquide intervalvaire - CLI) et dosage de la contamination en métaux lourds (plomb, cadmium et mercure), exprimé en mg/kg de chair humide. Le classement et le suivi des zones de production de coquillages distingue 3 groupes de coquillages au regard de leur physiologie : - groupe 1 : les gastéropodes (bulots etc.), les échinodermes (oursins) et les tuniciers (violets) ; plus généralement des coquillages sauvages de gisements naturels, - groupe 2 : les bivalves fouisseurs, c’est-à-dire les mollusques bivalves filtreurs dont l’habitat est constitué par les sédiments (palourdes, coques...) ; plus généralement des coquillages sauvages de gisements naturels, - groupe 3 : les bivalves non fouisseurs, c’est-à-dire les autres mollusques bivalves filtreurs (huîtres, moules...) ; plus généralement des coquillages d'élevage. Ce concept est bien distinct de celui de 'Zone de qualité des eaux conchylicoles'. Le contour de la Zone de production conchylicole ne correspond pas au cadastre conchylicole (= cadastre des établissements de culture marine).
