| Ce document s’adresse à un public large, familier ou non avec les problématiques couvertes par la Directive Cadre “Stratégie pour le Milieu Marin” (DCSMM). Ce public inclut donc le personnel intervenant sur la mise en oeuvre de la DCSMM, les scientifiques, et toute personne concernée par la surveillance de l’état de santé du milieu marin. L’objectif du document est de valoriser les travaux menés lors des essais du Programme de Surveillance de la DCSMM. Ces essais ont consisté à tester des protocoles visant à utiliser les campagnes océanographiques bentho-démersales et pélagiques existantes pour collecter les données indispensables à la construction et au renseignement d’indicateurs du Bon État Écologique. Cette collecte de données implique la participation... |

| Le dispositif « SELI » est mis en place depuis 2016 pour acquérir des données sur les effets biologiques intégrateurs de la contamination chimique chez des organismes marins (poissons et bivalves) et ainsi renseigner le critère 2 du descripteur 8 de la DCSMM (Le niveau de concentration des contaminants ne provoque pas d’effets dus à la pollution). Le présent rapport concerne le volet SELIseine. Des poissons plats (194 soles, flets et limandes) ont été prélevés en septembre 2018 sur le N/O Antéa, et des moules ont été prélevées en février 2019 sur 6 stations dans le cadre du suivi ROCCH MV suivant le protocole de la convention OSPAR (2012). Les biomarqueurs suivis chez ces organismes couvrent plusieurs types d’effets toxiques (reprotoxicité, génotoxicité,... |

Des soles ont été prélevées en août et septembre 2017 et des moules en février 2018, dans le cadre du suivi ROCCH MV. Les biomarqueurs suivis chez ces organismes couvrent plusieurs mécanismes d’actions toxiques (reprotoxicité, génotoxicité, neurotoxicité) et incluent des mesures de la santé générale de l'organisme. Les contaminants suivis sont des éléments traces métalliques et des contaminants organiques... |

| Good Environmental Status (GES) for descriptor 8 of MSFD is reached when concentrations of contaminants are at levels not giving rise to pollution effects. According to the decision 2017/848/CE, descriptor 8 is defined by four criteria: concentration in the relevant matrices (sediment, biota) (D8C1), effects of chronic contamination to the marine organisms (D8C2), duration and spatial extent of acute pollution events (D8C3), effects of acute contamination to the marine organisms (D8C4). The GES for descriptor 8 is assessed at the level of four marine subregions (SRM), including: Channel – North Sea (MMN), Celtics Seas (MC), Bay of Biscay (GdG) and the Occidental Mediterranean Sea (MO). In order to achieve GES, each indicator of descriptor 8 should respect... |

| According to Commission Decision (EU) 2017/848 under the Marine Strategy Framework Directive (MSFD), EU Member States (MS) shall consider, in their Descriptor 8 primary criterion (D8C1) assessments, the WFD Priority Substances (PS) and River Basin Specific Pollutants (RBSP) within coastal and territorial waters and also beyond territorial waters if these still may give rise to pollution effects. Some WFD PS might not be relevant for the marine environment in the open sea and, consequently, might be excluded from MSFD monitoring beyond the territorial waters. MS have expressed the need for a framework for the deselection of WFD PS from monitoring under the MSFD, in order to save resources. The European Commission’s Joint Research Centre (JRC), collaborating... |

| Investigating the drivers of fish assemblage trophic structure is a critical question, in order to better understand ecosystem functioning, predict the effects of perturbations and implement integrated management of exploited marine ecosystems. Ecosystemic surveys enabled the determination of the trophic structure of the fish assemblages in three French marine ecosystems, namely the Eastern English Channel, the Bay of Biscay and the Gulf of Lions, through the simultaneous collection of qualitative (stable isotopes and energy content) and quantitative (biomass) data. In the Bay of Biscay and in the Gulf of Lions, pelagic primary production supported at least 80% of the fish biomass production, and explained the dominance of pelagic species, but with... |

| We assessed the capacity of real-time PCR markers to identify the origin of contamination in shellfish. Oyster, cockles or clams were either contaminated with fecal materials and host-associated markers designed from Bacteroidales or Catellicoccus marimammalium 16S RNA genes were extracted from their intravalvular liquid, digestive tissues or shellfish flesh. Extraction of bacterial DNA from the oyster intravalvular liquid with FastDNA spin kit for soil enabled the selected markers to be quantified in 100% of artificially contaminated samples, and the source of contamination to be identified in 13 out of 38 naturally contaminated batches from European Class B and Class C areas. However, this protocol did not enable the origin of the contamination to be... |

| The relevance of three host-associated Bacteroidales markers (HF183, Rum2Bac, and Pig2Bac) and four F-specific RNA bacteriophage genogroups (FRNAPH I to IV) as microbial source tracking markers was assessed at the level of a catchment (Daoulas, France). They were monitored together with fecal indicators (Escherichia coli and enterococci) and chemophysical parameters (rainfall, temperature, salinity, pH, and turbidity) by monthly sampling over 2 years (n = 240 water samples) and one specific sampling following an accidental pig manure spillage (n = 5 samples). During the 2-year regular monitoring, levels of E. coil, enterococci, total F-specific RNA bacteriophages, and the general Bacteroidales marker AllBac were strongly correlated with one another and... |

| Based on the data gap analysis performed in the first step of MEDCIS, the Medcis team on contaminant proposed a road map associated with a time-schedule in order to improve harmonization in Mediterranean region for 2024 GES assessment. Partner countries shared information on monitored substances and biological effects, thresholds used, matrix/matrices used for the monitoring of each substance/family of substances, the limit of quantification (LQ) of each chemical measurement, and the proportion of censored data |
