An example of cooperation between scientist and managers : The Meditearranean Lagoon Network (Languedoc-Roussillon, France) ArchiMer
Laugier, Thierry; Malet, Nathalie; Munaron, Dominique; Derolez, Valerie; Fiandrino, Annie; Barral, Marc; Moragues, Laurent; Mazouni, Nabila; Graille, Chantal.
The poster presents the approach that led to the construction of a network of cooperation between managers and scientists for coastal lagoon management in the region of Languedoc-Roussillon, its architecture and modus operandi, its achievements and developments over time. At the end of the ninety’s, eutrophication and lack of knowledge were identified as issues to enhance the management of coastal lagoons on the Mediterranean coast of France. In 2000, in the region of Languedoc-Roussillon, scientists (Ifremer) and institutional managers (Regional Council of Languedoc-Roussillon and Water Agency Rhône-Méditerranée & Corse) joined their forces in building a network to address this need. The core of this network consists of an operational tool for the...

Analyse statistique des données du RSL - Etude des trajectoires écologiques des lagunes entre 2001 et 2012 ArchiMer
Derolez, Valerie; Ouisse, Vincent; Fiandrino, Annie; Munaron, Dominique; Bissery, Claire; Kloareg, Maela.
Les questions abordées dans le présent rapport concernent la recherche et l’interprétation d’un repère de représentation des données du RSL (colonne d’eau et phytoplancton) pour l’ensemble des stations des lagunes de Provence-Alpes Côte d’Azur (PACA), Languedoc-Roussillon (LR) et Corse : 1) Est-il possible de trouver un repère pertinent de représentation des trajectoires d’évolution pour toutes les stations, en effectuant des regroupement par typologie de stations ? Comment interpréter les deux premiers axes de l’analyse en composantes principales (ACP) ? 2) Le premier axe des repères d’ACP constitue-t-il un « Gradient d’eutrophisation » ? 3) Est-il possible de mettre en évidence un effet météorologique sur les évolutions des teneurs en azote et phosphore...

Application of POCIS for the monitoring of pesticides, pharmaceuticals and alkylphenols in marine water ArchiMer
Tapie, Nathalie; Munaron, Dominique; Gonzalez, Jean-louis; Budzinski, Helene.
With the new European legislation (the Water Framework Directive, 2000/60/EC), the decision makers responsible for the assessment of the environmental contamination require simple monitoring tools. Passive sampling methods seem to be promising tools for the sampling of polar organic compounds in water, especially in marine waters where important dilutions and low concentrations are usual. They are taking into account the temporal variability and integrating the contamination over period of time. This work presents a study, on a large scale, of the contamination of French Mediterranean coastal waters realized in partnership with the Water Agency Rhône Méditerranée Corse (AERMC), and Coastal Water Quality Offices (CQEL).

The Water Framework Directive (WFD) is probably the most significant legislation in the water field that has been introduced for many years. Several publications pointed out that passive samplers (PSs) can be valuable tools as complementary method in monitoring water quality in the context of the WFD However, there is still a lack of quality assurance and control (QA/QC) procedures that demonstrate the reliability and the comparability of results obtained by passive sampling. Up to date, very few in situ intercomparison exercises on PSs have been performed until now. To our knowledge only three pan-European or international intercomparison studies have been organized in situ since 2007 (ICES Passive sampling survey and intercalibration, AQUAREF, IPSIC and...

Assessment of chemical contamination of french coastal lagoons using passive sampling techniques. ArchiMer
Munaron, Dominique; Hubert, Morgane; Tapie, Nathalie; Budzinski, Helene; Guyomarch, Julien; Andral, Bruno; Gonzalez, Jean-louis.
Since 2008, projects supported by french government agencies were dedicated to improve the assessment of chemical contamination of water bodies defined by the Water Framework Directive (WFD, 2000/60/CE)(Munaron et al, 2012). Among these studies, the aim of PEPSLAG was to investigate the utility of passive samplers for sampling contaminants present at trace levels in coastal lagoons environments, and to realize a first assessment of the contamination on the French Mediterranean coastal lagoons. 23 transitional lagoons water-bodies were investigated along the French Mediterranean coast, using three kinds of passive samplers (DGT, POCIS and SBSE). 141 contaminants from various chemical families (trace metals, pesticides, pharmaceuticals, alkylphenols, PAHs,...

Assessment of eutrophication of French Mediterranean lagoons in relation to meteorological interannual variability ArchiMer
Malet, Nathalie; Derolez, Valerie; Laugier, Thierry; Munaron, Dominique; Fiandrino, Annie; Messiaen, Gregory; Fortune, Martine; Souchu, Philippe; Barral, Marc; Daloz, Aurélien; Moragues, Laurent.
Since recent decades, nutrient-related eutrophication, originating from agricultural use of fertilizer and population enhancement, can be considered worldwide as the main disturbance for coastal lagoons. Since coastal lagoons are very shallow and enclosed, their functioning is tightly linked to meteorological conditions. The aim of this study is to compare different rainfall levels and eutrophication response on coastal lagoons of the Languedoc-Roussillon (Western Mediterranean coast), subject to different nutrient loads from their watershed, in order to check the possibility to distinguish the effects of watershed management or rainfall conditions on water quality (waste water treatment plant improvement, decrease of fertilizer spreading).

Assessment of the Environmental Quality of French Continental Mediterranean Lagoons with Oyster Embryo Bioassay ArchiMer
Galgani, Francois; Senia, Jocelyn; Guillou, Jean-louis; Laugier, Thierry; Munaron, Dominique; Andral, Bruno; Guillaume, B.; Coulet, E.; Boissery, P.; Brun, L.; Bertrandy, M. C..
In order to better understand environmental disturbances in the French coastal Mediterranean lagoons, we used an ecotoxicological approach based on the measurement of the toxicity of the sediments using oyster embryo bioassay that provides a basis for assessing the effects on the fauna of contaminants adsorbed on the sedimentary particles. The study covers all of the main lagoons of the French Mediterranean coasts of Languedoc Roussillon, Camargue, and Provence (Berre and Bolmon lagoons), where 188 stations were sampled. The toxicity tests provide evidence of variable levels of toxicity in sediments. Contaminated lagoons such as La peyrade, Le canet, and Ingrill and locally affected lagoons such as Bages-Sigean, Vaccares, Bolmon, and Berre have sampling...

Assessment of the quantities of herbicides and nutrients brought down by the river Charente to the coast and modelling of the dispersion of atrazine in the Marennes-Oleron bay ArchiMer
Munaron, Dominique; Dubernet, Jf; Delmas, F; Stanisiere, Jean-yves; Scribe, P.
Our study aims at making progress the estimate of herbicide and nutrient inputs to the Marennes-Oleron bay which could influence summer oysters mortalities, and to bring, a better understanding of the impact on coastal ecosystems by modelling the dynamics of these compounds in the shellfish-farming area. The development of a strategy adapted to the river Charente and its estuary reveals that agricultural activity on the watershed area is omnipresent, as well on the level of the nitrogen as on the one of herbicides contributions. It is thus necessary to specify Charente fluxes, which is the main tributary of the Marennes-Oleron bay, in order to better characterize its impact on shell fish-farming activity. Hydrodynamic modelling will constitute an...

Bilan sur les principales pressions pesant sur les lagunes méditerranéennes et leurs liens avec l’état DCE ArchiMer
Derolez, Valerie; Fiandrino, Annie; Munaron, Dominique; Cadoret, Marine.
L’objectif de cette étude est de mettre en évidence et de hiérarchiser les pressions anthropiques ayant le plus d’impact sur les éléments de qualité DCE sur les lagunes méditerranéennes et de consolider ainsi les liens état/pressions. Il s’agit également de mettre en évidence des groupes de masses d’eau homogènes en termes de pressions. Ce travail s’appuie sur les précédentes études menées sur le sujet (Battut, 2010 ; Bouchoucha et al., 2010 ; Meinesz et al., 2013) et vise à les compléter grâce : • à la mise en œuvre d’une approche descriptive multidimensionnelle qui permet de mettre en évidence les interactions entre les différentes métriques de pression et d’état et de regrouper les masses d’eau similaires, • à l’intégration de données de pression et...

Campagne DCE 2009 : Utilisation des échantillonneurs passifs (DGT, POCIS, SBSE) pour l'évaluation au titre de la DCE de l'état chimique des eaux côtières méditerranéennes ArchiMer
Gonzalez, Jean-louis; Munaron, Dominique; Andral, Bruno; Sargian, Peggy; Tomasino, Corinne; Guyomarch, J.; Van Ganse, S..
Dans le périmètre de la Directive Cadre Européenne sur l’Eau (DCE), une campagne menée entre mars et avril 2009 (N.O. "L’Europe") a permis d'évaluer la qualité des eaux côtières méditerranéennes françaises. Les objectifs étaient de compléter les résultats acquis en 2006, de déterminer, grâce en grande partie à la mise en oeuvre de stations artificielles de moules (réseau RINBIO), la contamination chimique de l’eau. Afin de pouvoir mesurer les concentrations de contaminants chimiques (métaux composés organiques hydrophobes et hydrophiles), des échantillonneurs passifs (DGT, SBSE et POCIS) ont également été utilisés au cours de cette campagne. Les données obtenues ont contribué à la caractérisation des masses d'eau par rapport à certains contaminants sur...

Richard, Marion; Bec, Beatrice; Vanhuysse, Charles; Mas, Sébastien; Parin, David; Chantalat, Camila; Le Gall, Patrik; Fiandrino, Annie; Lagarde, Franck; Mortreux, Serge; Ouisse, Vincent; Rolland, Jean-luc; Degut, Anaïs; Hatey, Elise; Fortune, Martine; Roque D'Orbcastel, Emmanuelle; Messiaen, Gregory; Munaron, Dominique; Callier, Myriam; Oheix, Jocelyne; Derolez, Valerie; Mostajir, Behzad.
Oysters modify the planktonic microbial community structure by their filtration and NH4 excretion activities. While many studies have been conducted on this subject with adult oysters, none had been carried out in situ with juveniles. Pacific oyster juveniles (Magallana gigas, previously Crassostrea gigas) died massively all over the world since 2008 in relation with OsHV-1 infection. During mortality episodes, sick and dead oysters are not separated from healthy live ones, and left to decay in the surrounding environment, with unknown consequences for the nutrient cycle and planktonic microbial components (PMC). The present study aimed to elucidate for the first time the interactions between oyster juveniles and PMC during a mortality episode. Innovative...

Etude de Ruppia cirrhosa dans la lagune de Canet‐St‐Nazaire ArchiMer
Oheix, Jocelyne; Ouisse, Vincent; Munaron, Dominique; Le Fur, Ines; Derolez, Valerie.
L'herbier de Ruppia cirrhosa a connu des périodes de fortes régressions et de reprises dans la lagune de Canet-St-Nazaire. Pour mieux comprendre ces fluctuations, une étude bibliographique de la physiologie de la phanérogame Ruppia cirrhosa est réalisée, associée à l'analyse des données disponibles dans la lagune de Canet (acquises notamment dans le cadre du Réseau de Suivi Lagunaire). Les éléments influant sur le développement ou la régression de Ruppia cirrhosa sont étudiés à la lumière des connaissances bibliographiques. L'eutrophisation et la contamination chimique, associées à des paramètres environnementaux parfois défavorables ont pu contribuer au déclin de l'herbier après 2002. Les conditions qui ont permis la reprise de l'herbier à partir de 2011...

First steps of ecological restoration in Mediterranean lagoons: Shifts in phytoplankton communities ArchiMer
Leruste, A.; Malet, Nathalie; Munaron, Dominique; Derolez, Valerie; Hatey, E.; Collos, Y.; De Wit, R.; Bec, B..
Along the French Mediterranean coast, a complex of eight lagoons underwent intensive eutrophication over four decades, mainly related to nutrient over-enrichment from continuous sewage discharges. The lagoon complex displayed a wide trophic gradient from mesotrophy to hypertrophy and primary production was dominated by phytoplankton communities. In 2005, the implementation of an 11 km offshore outfall system diverted the treated sewage effluents leading to a drastic reduction of anthropogenic inputs of nitrogen and phosphorus into the lagoons. Time series data have been examined from 2000 to 2013 for physical, chemical and biological (phytoplankton) variables of the water column during the summer period. Since 2006, total nitrogen and phosphorus...

Influence of OSHV-1 oyster mortality episode on dissolved inorganic fluxes: An ex situ experiment at the individual scale ArchiMer
Richard, Marion; Bourreau, Juliette; Montagnani, Caroline; Ouisse, Vincent; Le Gall, Patrik; Fortune, Martine; Munaron, Dominique; Messiaen, Gregory; Callier, Myriam; Roque D'Orbcastel, Emmanuelle.
Ostreid herpesvirus 1 (OsHV-1 μvar) infection has caused significant mortalities in juvenile oysters (Crassostrea gigas). In contrast to the practices of other animal production industries, sick and dead oysters are not separated from live ones and are left to decay in the surrounding environment, with unknown consequences on fluxes of dissolved materials. A laboratory approach was used in this study to test the influence of oyster mortality episode on dissolved inorganic fluxes at the oyster interface, dissociating (i) the effect of viral infection on metabolism of juvenile oysters and (ii) the effect of flesh decomposition on oxygen consumption and nutrient releases at the individual scale. Nine batches of juvenile oysters (Individual Total wet weight...
