The European Tracking Network (ETN) aims at bringing together marine researchers based in Europe that use aquatic biotelemetry as a tool. The main goals of the network are the promotion of transboundary cooperation, the establishment of a pan-European aquatic telemetry infrastructure network, improved data sharing through a central data portal and enhanced funding opportunities. ETN is co-coordinated by IMAR/University of the Azores and the Canadian Ocean Tracking Network (OTN) initiative. ETN is a partner node of OTN. The central data platform is hosted by the Flanders Marine Institute (VLIZ) and provides three key services to the users. 1) Data and metadata are stored centrally at a PostgreSQL database. To facilitate the data entry and data management for the users, a web application was developed in PHP using Symfony framework. 2) A data explorer is available to visualize the data. Datasets can be filtered based on area, species or time frame. In addition, detection data can be linked to other data types ( (e.g. moon index and tides) and several plot options are available. 3) In the R-studio environment, more detailed analyses can be performed.

L'État a confié à l'IGN le développement du référentiel à grande échelle (RGE). Pour ce faire, il fait appel à ses moyens propres ainsi qu’à des partenariats avec des producteurs principalement de la sphère publique. Le RGE est constitué de 5 composantes: - orthophotographique (BD ORTHO), - topographique (BD TOPO), - adresse (BD adresse), - parcellaire (BD parcellaire) - et altimétrique (RGE ALTI). Remarque : seules les BD TOPO thème hydrographique, BD ORTHO 5m, BD ORTHO 50 cm sont sous Licence Ouverte. Les autres données du RGE sont soumises aux licences IGN. ----- Etat de la disponibilité de la donnée (sous Licence Ouverte): - Data.gouv : les BD TOPO thème hydrographique, BD ORTHO 5m, BD ORTHO 50 cm (pour certains départements) sont accessibles sous format shape, xml et htlm. Mise à jour irrégulière. - PIGMA : données BD ORTHO 50 cm (2015) et BD TOPO v2.2 (2016) accessibles au format shape sous licence IGN. Aucune mise à jour. - Géocatalogue : données BD ORTHO v2 (2013) au format Tif et BD TOPO v2.1 (2015) au format shape, MIF/MID accessibles sous licence IGN. Aucune mise à jour. - IGN : renvoi direct au site IGN où les données sont téléchargeables au format JPEG et shape sous licence IGN. Mise à jour irrégulière.

Temporal series (annual mean values) and Long term Average (LTA) of water discharge for each river mouth where in situ data is available. Different sources can be mixed if any.

Calculation of the average annual sediment balance per stretch of coast for the past 50 years for all coastal zones bordering the North Atlantic Ocean. For this scale of study, this has been interpreted in terms of shoreline advance / retreat in mm/year. Required data sources are therefore national or international datasets giving this parameter directly. It is also possible to utilise more aggregated data sources, but annual values would then be approximated from them. The main challenge in producing this product lies with obtaining datasets which include this data from multiple countries and potentially multiple languages, since this data is usually produced as a result of comparatively small scale studies.

The SeaDataNet aggregated datasets over the Atlantic Ocean are regional ODV historical collections of all temperature and salinity measurements contained within SeaDataNet database and covering 3 European sea basins: North Arctic Ocean, North Sea, North Atlantic Ocean. Two versions have been published during SeaDataNet 2 and they represent a snapshot of the SeaDataNet database content at two different times: • V1.1 January 2014 • V2 March 2015 Each of them is the result of the Quality Check Strategy (QCS) implemented during SeaDataNet 2 that contributed to highly improve the quality of temperature and salinity data. The QCS is made by four main phases: 1. data harvesting from the central CDI 2. file and parameter aggregation 3. quality check analysis at regional level 4. analysis and correction of data anomalies. The aggregated datasets have been prepared and quality checked using ODV software.

This data product selects sample areas of digital bathymetry, chosen for their relevance to marine activities and data sources alternative to GEBCO. The approach for building the digital map of water depth is to use GEBCO as a baseline and look at a set of sample areas where GEBCO could be improved upon. Sample areas have also been selected to be representative of each continent bordering the Atlantic and expected future requirements. Data sources include GEBCO, EMODNET, USGS and CHS.

Combined product of Water body chlorophyll a based on DIVA 4D 10-year analysis on five regions : Northeast Atlantic Ocean, North Sea, Baltic Sea, Black Sea, Mediterranean Sea. The boundaries and overlapping zones between these five regions were filtered to avoid any unrealistic spatial discontinuities. This combined Water body chlorophyll a product is masked using the relative error threshold 0.5. Units: mg/m^3. Created by 'University of Liege, GeoHydrodynamics and Environment Research (ULg-GHER)'.
