Les périmètres des quartiers prioritaires de la politique de la ville sont fixés par le décret n° 2014-1750 du 30 décembre 2014 pour la métropole et par le décret n° 2014-1751 du 30 décembre 2014 pour les départements et collectivités d’outre-mer, rectifiés par le décret n°2015-1138 du 14 septembre 2015.

The aim of this project is to develop an eco-physiological model to predict production flow of certain species of planktonic Foraminifera, which are representative of the main ecological system, as well as their habitat (depth, season), from climate forcing. The eco-physiological and geochemical/isotopic characteristics must be determined by the data obtained during cruises. The data from closing nets and sediment traps will be used to evaluate flows from different Foraminifera and the acquisition of their isotope and geochemical signals according to the depth of their habitat and their development cycle. The project is linked to ANR FORCLIM (coordinator L.Labeyrie, LSCE). Data is organised into two parts : 1/ measurements of physiochemical and biogeochemical parameters in the water column ; inventory of planktonic Foraminifera - 2/ Measurements of biogeochemical parameters and the interface between sediment and water: inventory of benthic Foraminifera fauna. The campaign is connected to the STEEPL Observation Service (Temporal monitoring of benthic and planktonic ecosystems in the Landes plateau) – OSUNA funding (Nantes Angers Sciences of the Universe Observatory).

This is not a particular project or programme, but a reminder of the existence of acoustic observatories ("polygons") within the Ministry of Defence which are capable of fulfilling MSFD monitoring needs. For military needs, the Ministry of Defence uses its permanent equipped sites for its activities and experiments. Measurements of interest to MSFD (monitoring impulse broadcast and acquisition of long time series of traffic noise) could be conducted, at least in part, on these sites. These measurements, when made available, could be compiled and used for monitoring environmental status.

The regional bathymetric Atlantic – Channel – North-Sea DTM has a resolution of 0.001° (~111m). Its geographic coverage includes the Bay of Biscay, the English Channel and a part of the North Sea. The DTM extends from the coast to the continental slope (about of 4800m deep). This DTM is produced in the framework of the HOMONIM project which aims at improving operational forecast capabilities for the national coastal flood warning system. This DTM is offered openly on the Shom diffusion website (http://diffusion.shom.fr/produits/bathymetrie/mnt-facade-atl-homonim.html). http://dx.doi.org/10.17183/MNT_ATL100m_HOMONIM_WGS84

The definitive coastal information system, Quadrige stores coastal observation and monitoring network data. In order to manage coastal monitoring data, Ifremer developed the Quadrige² information system. Quadrige is one element of the Water Information System (SIE) http:// www.eaufrance.fr, et à ce titre, contribue aux travaux du Secrétariat d'Administration National des Données Relatives à l'Eau (SANDRE) http://www.sandre.eaufrance.fr. Quadrige Marine Zones is a reference source unique to the Quadrige system. It is used to break down the coast of the French mainland and overseas territories into large areas and to connect each one with observation and monitoring locations.

3D PREVIMER Modelling : current, temperature, salinity and turbidity in the English Channel and Bay of Biscay Modélisation Period 2010-2013 + 4-day forecasts

The PREVIMER demonstrator is designed for a wide audience, including those who want to obtain short term coastal environmental forecasts for the Channel, Atlantic and Mediterranean coasts, be it for private or professional purposes.

The national observation network for the blue mussel (MYTILOBS), set up in 2012, aims to monitor the growth and mortality of mussels produced for the market. The MYTILOBS is based on the experience of the regional network (REMOULA) which has been monitoring the growth of the blue mussel in the Charentais inlet since 2000. Monitoring mainly takes place the year following the year of capture: it thus integrates the main seasons of the biological life of the mussel, from winter maturation to spring growth, then to summer and fall fattening, the two periods when they are mainly sold. The choice of monitoring sites was decided in consultation between the Regional Environmental Resource Laboratories and the industry. For North Brittany, this is the site of Vivier-sur-Mer in (the sector of) the bay of Mont-Saint-Michel (mussel poles). Each breeding site is monitored every three months. Many parameters are measured including mussel size, weight and mortality. These data are examined taking into account environmental conditions such as temperature, salinity or the abundance and richness of the microalgae on which the shellfish feed. The Mytilobs national network is located in the main mussel-breeding regions of the Atlantic coast: Normandy, North Brittany, South Brittany, Pays de Loire and Poitou-Charentes. The sites of Agon (West Cotentin), Vivier (the bay of Mont Saint-Michel), Pont Mahe (Vilaine bay), Aiguillon (Breton inlet), Yves (Pertuis d’Antioche strait) representing, from north to south, mussel culture using poles. The Filiere site (Pertuis Breton - strait) represents mussels culture using ropes, in full water.

The “World Seabed Sediment Map” product contains geo-referenced digital data, describing the nature of the sediment encountered in different seas and oceans of the world. The objects are all surface areas and the description of an object includes in particular the nature of the sediment including rock-type bottoms.
