Évaluation du descripteur 5 « Eutrophisation » en France métropolitaine. Rapport scientifique pour l’évaluation 2018 au titre de la DCSMM ArchiMer
Devreker, David; Lefebvre, Alain.
This report is the second assessment of French marine water eutrophication status (descriptor 5) done in the framework of the MSFD. The goal of this report is to determine if French marine water reach the Good Ecological State as defined by the MSFD. It stands next to the initial evaluation made in 2012, from which it is an update. It introduces the second cycle of the Marine Environment Action Program. It shows that French marine waters, behind the 12 nm line, reach the GES as defined by the MSFD. Problems link to eutrophication occurs in marine waters above the 12 nm, where 6.5% of the area do not reach the GES.

Exploring Change in the Relative Abundance of Marine Megafauna in the Bay of Biscay, 2004-2016 ArchiMer
Authier, Matthieu; Doremus, Ghislain; Van Canneyt, Olivier; Boubert, Jean-jacques; Gautier, Gerard; Doray, Mathieu; Duhamel, Erwan; Masse, Jacques; Petitgas, Pierre; Ridoux, Vincent; Spitz, Jerome.
Conservation has moved from species-centered to ecosystem-based approaches: the Marine Strategy Framework Directive requires the maintenance or restoration of ‘Good Environmental Status’ of all European marine waters. Monitoring biodiversity at the scale of whole ecosystems is salient, but challenging owing to the large spatial scale involved and the large spatio-temporal heterogeneity of marine ecosystems. We capitalized on the integrated ecosystemic PELGAS survey carried out in spring in the Bay of Biscay to document patterns of change in marine megafauna relative abundance at the community level over more than a decade (2004-2016). The relative abundance of the twenty three most frequently sighted species (6 cetaceans and 17 seabirds) was estimated by...

High frequency mesozooplankton monitoring: Can imaging systems and automated sample analysis help us describe and interpret changes in zooplankton community composition and size structure — An example from a coastal site ArchiMer
Romagnan, Jean-baptiste; Aldamman, Lama; Gasparini, Stephane; Nival, Paul; Aubert, Anais; Jamet, Jean Louis; Stemmann, Lars.
The present work aims to show that high throughput imaging systems can be useful to estimate mesozooplankton community size and taxonomic descriptors that can be the base for consistent large scale monitoring of plankton communities. Such monitoring is required by the European Marine Strategy Framework Directive (MSFD) in order to ensure the Good Environmental Status (GES) of European coastal and offshore marine ecosystems. Time and cost-effective, automatic, techniques are of high interest in this context. An imaging-based protocol has been applied to a high frequency time series (every second day between April 2003 to April 2004 on average) of zooplankton obtained in a coastal site of the NW Mediterranean Sea, Villefranche Bay. One hundred eighty four...

Identifying marine pelagic ecosystem management objectives and indicators ArchiMer
Trenkel, Verena; Hintzen, Niels T.; Farnsworth, Keith D.; Olesen, Christian; Reid, David; Rindorf, Anna; Shephard, Samuel; Dickey-collas, Mark.
International policy frameworks such as the Common Fisheries Policy and the European Marine Strategy Framework Directive define high-level strategic goals for marine ecosystems. Strategic goals are addressed via general and operational management objectives. To add credibility and legitimacy to the development of objectives, for this study stakeholders explored intermediate level ecological, economic and social management objectives for Northeast Atlantic pelagic ecosystems. Stakeholder workshops were undertaken with participants being free to identify objectives based on their own insights and needs. Overall 26 objectives were proposed, with 58% agreement in proposed objectives between two workshops. Based on published evidence for pressure-state links,...

Integrated indicator framework and methodology for monitoring and assessment of hazardous substances and their effects in the marine environment ArchiMer
Vethaak, A. Dick; Davies, Ian M.; Thain, John E.; Gubbins, Matthew J.; Martinez-gomez, Concepcion; Robinson, Craig D.; Moffat, Colin F.; Burgeot, Thierry; Maes, Thomas; Wosniok, Werner; Giltrap, Michelle; Lang, Thomas; Hylland, Ketil.
Many maritime countries in Europe have implemented marine environmental monitoring programmes which include the measurement of chemical contaminants and related biological effects. How best to integrate data obtained in these two types of monitoring into meaningful assessments has been the subject of recent efforts by the International Council for Exploration of the Sea (ICES) Expert Groups. Work within these groups has concentrated on defining a core set of chemical and biological endpoints that can be used across maritime areas, defining confounding factors, supporting parameters and protocols for measurement. The framework comprised markers for concentrations of, exposure to and effects from, contaminants. Most importantly, assessment criteria for...

Marine litter within the European Marine Strategy Framework Directive ArchiMer
Galgani, Francois; Hanke, Georg; Werner, S.; De Vrees, L..
There have been numerous anthropogenic-driven changes to our planet in the last half-century. One of the most evident changes is the ubiquity and abundance of litter in the marine environment. The EU Marine Strategy Framework Directive (MSFD, 2008/56/EC) establishes a framework within which EU Member States shall take action to achieve or maintain good environmental status (GES) of their marine waters by 2020. GES is based on 11 qualitative descriptors as listed in Annex I of the MSFD. Descriptor 10 (D 10) concerns marine litter. As a follow-up to the related Commission Decision on criteria and methodological standards (2010/477/EU) in which 56 indicators for the achievement of GES are proposed, the EC Directorate-General for the Environment, on the...

Monitoring the impact of litter in large vertebrates in the Mediterranean Sea within the European Marine Strategy Framework Directive (MSFD): constraints, specificities and recommendations ArchiMer
Galgani, Francois; Claro, F.; Depledge, M.; Fossi, C..
In its decision (2010/477/EU) relating to the European Marine Strategy Framework Directive (MSFD, 2008/56/EC), the European Commission identified the following points as focuses for monitoring: (i) 10.1.1: Trends in the amount, source and composition of litter washed ashore and/or deposited on coastlines, (ii) 10.1.2: Trends in the amount and composition of litter in the water column and accumulation on the sea floor, (iii) 10.1.3: Trends in the amount, distribution and composition of micro-particles (mainly microplastics), and (iv) 10.2.1 Trends in the amount and composition of litter ingested by marine animals. Monitoring the impacts of litter will be considered further in 2014. At that time, the strategy will be discussed in the context of the...

No more reason for ignoring gelatinous zooplankton in ecosystem assessment and marine management: Concrete cost-effective methodology during routine fishery trawl surveys ArchiMer
Aubert, A.; Antajan, Elvire; Lynam, C.; Pitois, S.; Pliru, A.; Vaz, Sandrine; Thibault, D..
Gelatinous zooplankton, including cnidarians, ctenophores, and tunicates (appendicularians, pyrosomes, salps and doliolids), are often overlooked by scientific studies, ecosystem assessments and at a management level. Despite the important economic consequences that they can have on human activities and on the marine foodweb, arguments often related to the costs of monitoring or their coordination, or simply negligence, have resulted in the absence of relevant monitoring programs. A cost-effective protocol has been applied on trawling from existing fishery surveys conducted by national laboratories in England and France. The testing phase has successfully demonstrated the adequacy of such a tool to sample macro- and mega-zooplankton gelatinous organisms in...

Pelagic habitats in the Mediterranean Sea: A review of Good Environmental Status (GES) determination for plankton components and identification of gaps and priority needs to improve coherence for the MSFD implementation ArchiMer
Varkitzi, I.; France, J.; Basset, A.; Cozzoli, F.; Stanca, E.; Zervoudaki, S.; Giannakourou, A.; Assimakopoulou, G.; Venetsanopoulou, A.; Mozetic, P.; Tinta, T.; Skejic, S.; Vidjak, O.; Cadiou, Jean-francois; Pagou, K..
At present there is no consistent approach for the definition of Good Environmental Status (GES) and targets in the Mediterranean Sea, especially for Biodiversity Descriptors, according to the Article 12 of the Marine Strategy Framework Directive (MSFD). The use of plankton indicators in the Mediterranean Sea refers mostly to pelagic habitats in coastal waters and to case studies connected with environmental pressures, e.g. in the Adriatic, Aegean etc. The aim of this review is to study the existing biodiversity indicators for different plankton groups in order to compare GES definitions for the Biodiversity Descriptor and identify the relevant gaps and priority needs to improve coherence for the MSFD implementation across the Mediterranean. For these...

Synthèse bibliographique relative à la notion d'indicateur dans le contexte de la Directive Cadre Stratégie pour le Milieu Marin (DCSMM) ArchiMer
Brun, Melanie; Soudant, Dominique.
Stakeholders of the Marine Strategy Framework Directive (MSFD) need scientific and technical support to assess ecological status of marine waters and to adopt management actions to achieve the objective of the directive, i.e. “to achieve or to maintain good environmental status in the [European] marine environment by the year 2020 at the latest”. This support involves especially the development of indicators. Studies about the concept of indicator exist, in particular since the implementation of legislations such as the Water Framework Directive (WFD) in Europe. Indeed, they provide a significant source of reports and scientific papers, representing essential information for the implementation of the MSFD. However, the generic nature of the concept of...

Testing CPUE-derived spatial occupancy as an indicator for stock abundance: application to deep-sea stocks ArchiMer
Trenkel, Verena; Beecham, Jonathan A.; Blanchard, Julia L.; Edwards, Charles T. T.; Lorance, Pascal.
The status of an exploited population is ideally determined by monitoring changes in abundance and distributional range and pattern over time. Area of occupancy is a measure of the current distribution. Unfortunately, for many populations, scientific abundance and distribution information is not readily available. To evaluate the reliability of commercial fishing data for deriving occupancy indicators that could serve as proxies for stock abundance, we investigated four questions: 1) Occupancy changes with stock biomass, but is this change strong enough to make occupancy a sensitive indicator of population biomass? 2) Fishing boats follow fish, but when does such activity alter the positive macroecological relationship between occupancy and abundance? 3)...
