EMODnet Bathymetry - World Coastline version 2022

The EMODnet Bathymetry World Coastline is available as a WFS service from EMODnet Bathymetry. The service URL is: https://ows.emodnet-bathymetry.eu/wfs. The layer contains vector lines derived from land polygons available from OpenStreetMap. The original source url is https://osmdata.openstreetmap.de/. Parts of these polygons have been modified for use in EMODnet Bathymetry.
In addition to the OSM EMODnet default coastline, three sub-layers are available as part of the EMODnet world coastline service. These sub-layers contain the best-estimate coastlines for Europe determined by Dutch research institute Deltares from satellite data (typically Sentinel-2 and Landsat-8) and in combination with the Global Tide Surge Model (GTSM) processed into digital coastlines for the European seas at LAT (Lowest Astronomical Tide), MSL (Mean-Sea-Level), and MHW (Mean-High-Water). The level of detail is bound to the resolution of the satellite sensor (e.g. 10m for Sentinel-2). The latest December 2022 version covers the entire coastline of Europe and now also part of the Caribbean. 
A detailed paper is available describing the methodology used to determine the three versions of the satellite derived coastline:

Contaminants-Mercury: stations below LOD/LOQ v2019

This product displays the stations where mercury has been measured and the values present in EMODnet Chemistry infrastructure are always below the limit of detection or quantification (LOD/LOQ), i.e quality values found in EMODnet validated dataset can be equal to 6 or Q.
It is necessary to take into account that LOD/LOQ can change with time. These products aggregate data by station, producing only one final value for each station (above, below or above/below).  
EMODnet Chemistry has included the gathering of contaminants data since the beginning of the project in 2009. 
For the maps for EMODnet Chemistry Phase III, it was requested to plot data per matrix (water,sediment, biota), per biological entity and per chemical substance. 
The series of relevant map products have been developed according to the criteria D8C1 of the MSFD Directive, specifically focusing on the requirements under the new Commission Decision 2017/848 (17th May 2017). The Commission Decision points to relevant threshold values that are specified in the WFD, as well as relating how these contaminants should be expressed (units and matrix etc.) through the related Directives i.e. Priority substances for Water. EU EQS Directive does not fix any threshold values in sediments. On the contrary Regional Sea Conventions provide some of them, and these values have been taken into account for the development of the visualization products.
To produce the maps the following process has been followed:
    1. Data collection through SeaDataNet standards (CDI+ODV)
    2. Harvesting, harmonization, validation and P01 code decomposition of data
    3. SQL query on data sets from point 2 
    4. Production of map with each point representing at least one record that match the criteria
The harmonization of all the data has been the most challenging task considering the heterogeneity of the data sources, sampling protocols.
Preliminary processing were necessary to harmonize all the data :
    • For water: contaminants in the dissolved phase;
    • For sediment: data on total sediment (regardless of size class) or size class < 2000 μm
    • For biota: contaminant data will focus on molluscs, on fish (only in the muscle), and on crustaceans
    • Exclusion of data values equal to 0

EMODnet Human Activities, Environment, Status of Bathing Water

The dataset on the status of bathing waters in the European seas was created in 2015 by Cogea for the European Marine Observation and Data Network (EMODnet). It is based on the 'Bathing Water' Directive 2006/7/EC of the European Parliament and of the Council of 15 February 2006 concerning the management of bathing water quality and repealing Directive 76/160/EEC. It is available for viewing and download on EMODnet web portal (Human Activities, https://emodnet.ec.europa.eu/en/human-activities). The Bathing Water Directive requires to identify popular bathing places in fresh and coastal waters and monitor them for indicators of microbiological pollution (and other substances) throughout the bathing season which runs from May to September. The purpose of the Directive is to protect human health and the environment while ensuring safe bathing water quality through provisions for monitoring, classification and management of bathing water quality, as well as for public information on such quality. More information are available at https://rod.eionet.europa.eu/obligations/787. The dataset presents information on bathing water identifier and name, country code and name, latitude and longitude of sites, specialized zone type (coastal, lake, river, transitional), link to the bathing water website page, bathing water quality status (0 - Not classified, 1 - Excellent, 2 - Good, 3 - Good or Sufficient, 3 - Sufficient, 4 - Poor, Closed, Insufficiently Sampled), year (1990-2025, where available). Only coastal and transitional bathing waters are shown on the EMODnet map viewer, while the dataset also contains lake and river ones. Geographic coverage: Albania, Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Guernsey, Hungary, Ireland, Isle of Man, Italy, Jersey, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom (England, Gibraltar, Northern Ireland, Scotland, Wales). Classifications were not made for some of the UK sites for the 2020 season due to the impact of the COVID-19 pandemic on the sampling programme. Compared with the previous version, the dataset has been updated according to the latest version published by the resource providers in the 2024 and 2025.
