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.

Data from a number of different sources have been integrated to provide new perspectives on fishing activities. Vessel Monitoring Systems (VMS) record and transmit the position and speed of fishing vessels at intervals of two hours or less. Fishing time can be calculated from the VMS data and combining this parameter with vessel logbook data, maps of fishing effort and intensity at different spatial and temporal scales can be calculated. The statistical software package “R” is used to extract the required information then re-interrogated to produce maps of fishing effort or intensity per month and year. The use of Automatic Identification System (AIS) data was not considered as combining AIS data with fisheries logbook data would pose issues namely; the ability of the AIS system to be switched off, only mandatory on vessels > 15 meters in length, cost involved to purchase data, and confidentiality.

Le Référentiel de l’organisation administrative de l’Etat, nouvelle appellation de la base, comprend toutes les institutions régies par la Constitution de la Ve République et les administrations qui en dépendent, soit environ 6000 organismes. Le périmètre couvre les services centraux de l’Etat, jusqu’au niveau des bureaux. --- Etat de disponibilité de la donnée : - Data.gouv : donnée téléchargeable au format rdf et mise à jour hebdomadaire. Aucun millésime antérieur à 2017.

Temporal series (annual mean values) with error of estimation and Long Term Average (LTA) with error of estimation of total nitrogen load for each river mouth where in situ data is available. Different sources can be mixed if any.

Historiquement l'Agence Technique Départementale a été créée pour accompagner les maîtres d'ouvrage dans la réalisation des bâtiments ou infrastructures communaux. Elle a depuis développé un savoir-faire particulier grâce à une équipe technique performante pour accompagner les élus dans l'aide à la décision ou plus largement dans les réflexions à mener sur leur territoire. Aujourd'hui, avec le désengagement progressif des services d'ingénierie de l'Etat, l'ATD permet de conserver pour les collectivités Territoriales qui y adhèrent une offre d'ingénierie publique Territoriale compétente. Les missions statutaires constituées par les études de faisabilité ou de simple diagnostic sont désormais complétées par des missions d'assistance technique en phase pré-opérationnelles réalisées uniquement dans le cadre de prestations intégrées. L'ensemble de ces missions reste strictement circonscrit dans la sphère du maître d'ouvrage, l'ATD n'assurant pas de mission de maîtrise d'œuvre.

The Global Sea Level Observing System (GLOSS) was established by the Intergovernmental Oceanographic Commission (IOC) of UNESCO in 1985 to establish a well-designed, high-quality in situ sea level observing network to support a broad research and operational user base. Various tide gauge networks have contributed to GLOSS, each with a different focus and each changing over time as research priorities evolve. The main component is the GLOSS Core Network (GCN), a global set of ~300 tide gauges that serves as the backbone of the global in situ sea level network. GCN gauges were allocated to each island or group of islands at intervals not closer than 500 km, and along continental coasts at intervals generally not less than 1000 km. Preference was given to islands in order to maximise exposure to the open ocean. Established in 1933, the Permanent Service for Mean Sea Level (PSMSL) is responsible for the collection, publication, analysis and interpretation of sea level data from the global network of tide gauges, including the GLOSS Core Network.

This product is a map of the uncertainty of available digital bathymetry measurements for the North Atlantic Ocean. This is done for a spatial resolution feasible for this large area (25km x 25km). It is designed to assess the quality of the bathymetry readings with a view to supporting assessments of future need. The product is formulated through a number of characteristics of the data including age of measurement and slope.
