Multiple biomarkers of pollution effects in caged mussels on the Greek coastline
Provedor de dados: 5
Autores: Tsangaris, C.; Kormas, K.; Strogyloudi, E.; Hatzianestis, I.; Neofitou, C.; Andral, Bruno; Galgani, Francois.
A suite of biomarkers was measured in caged mussels at areas impacted by different anthropogenic activities along the Greek coastline to assess biological effects of environmental pollution. Mussels were caged at coastal sites in the vicinity of major cities, in areas influenced by major industries, agricultural practices and in islands away from known sources of pollution. Biomarkers indicative of neurotoxicity (acetylcholinesterase, AchE), oxidative stress (catalase, CAT), phase 11 biotransformation of xenobiotics (glutathione S-transferase, GST), metal exposure (metallothioneins, MTs) and protein synthesis (RNA:DNA ratio) were measured to assess effects of various types of pollutants. AchE activity proved to be the most responsive biomarker with...

The Mytilos project was carried during the last 3 years (2004-2006) in order to evaluate the level of chemical contamination along the coasts of the western basin of the Mediterranean Sea. Active mussel watch consisted of caged (12 weeks) Mytilus galloprovincialis at 123 stations along the Mediterranean coasts of Spain, France, Italy, North Tunisia, Algeria and Morocco. Results indicated total PAHs levels in the range 22-106 mu g/kg dry weight. All large towns or industrial areas from all countries of the basin were affected. Analysis of the origin of contamination demonstrated mainly a pyrolytic origin except in some areas such as Maddalena, Napoli, Alger, and Cornigliano (Genova). Statistical analysis of the PAHs accumulation data enabled the...

Connectivity patterns of coastal fishes following different dispersal scenarios across a transboundary marine protected area (Bonifacio strait, NW Mediterranean)
Provedor de dados: 5
Autores: Koeck, Barbara; Gerigny, Olivia; Durieux, Eric Dominique Henri; Coudray, Sylvain; Garsi, Laure-helene; Bisgambiglia, Paul-antoine; Galgani, Francois; Agostini, Sylvia.
The Strait of Bonifacio constitutes one of the rare transboundary Marine Protected Areas (MPA) of the Mediterranean Sea (between Sardinia, Italy and Corsica, France). Based on the hypothesis that no-take zones will produce more fish larvae, compared to adjacent fished areas, we modeled the outcome of larvae released by coastal fishes inside the no-take zones of the MPA in order to: (i) characterize the dispersal patterns across the Strait of Bonifacio; (ii) identify the main potential settlement areas; (iii) quantify the connectivity and the larval supply from the MPAs to the surrounding areas. A high resolution hydrodynamic model (MARS 3D, Corse 400m) combined to an individual based model (Ichthyop software) was used to model the larval dispersal of fish...

Arsenic in marine sediments from French Mediterranean ports: Geochemical partitioning, bioavailability and ecotoxicology
Provedor de dados: 5
Autores: Mamindy-pajany, Yannick; Hurel, Charlotte; Geret, Florence; Galgani, Francois; Battaglia-brunet, Fabienne; Marmier, Nicolas; Romeo, Michele.
This work investigates arsenic mobility, bioavailability and toxicity in marine port sediments using chemical sequential extraction and laboratory toxicity tests. Sediment samples were collected from two different Mediterranean ports, one highly polluted with arsenic and other inorganic and organic pollutants (Estaque port (EST)), and the other one, less polluted, with a low arsenic content (Saint Mandrier port (SM)). Arsenic distribution in the solid phase was studied using a sequential extraction procedure specifically developed for appraising arsenic mobility in sediments. Toxicity assessment was performed on sediment elutriates, solid phases and aqueous arsenic species as single substance using the embryotoxicity test on oyster larvae (Crassostrea...

Marine litter, future prospects for research
Provedor de dados: 5
Autores: Galgani, Francois.
As far back as 1870, i.e., about 150 years ago, Jules Verne described the accumulation of debris in the convergence zone of the North Atlantic Ocean in his famous novel entitled “Twenty Thousand Leagues under the Sea.” Many scientific reports have addressed this topic since and our main concern today is the ever increasing volume of marine litter invading the oceans in various and complex ways. One of the current main challenges is assessing the final destination of this litter. To date, its adverse effects on marine life have only occasionally been investigated and many questions remain unanswered. In addition to efforts to monitor and reduce litter, recent literature has underlined the scientific community's focus on specific issues such as (i) the...

Autores: Van Sebille, Erik; Wilcox, Chris; Lebreton, Laurent; Maximenko, Nikolai; Hardesty, Britta Denise; Van Franeker, Jan A.; Eriksen, Marcus; Siegel, David; Galgani, Francois; Law, Kara Lavender.
Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they have primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models...

Dès le 4 JUIN 1992, un ostréiculteur digne de confiance avait signalé aux services d'IFREMER, une situation anormale sur le banc de Ronce les Bains. Un premier prélèvement a été effectué le jour même. En effet, ce secteur avait déjà été le lieu de mortalités d'huitres estimées à 7 000 tonnes, au printemps 1988, et s'est révélé par le passé comme étant un endroit sensible. Pour information, figure en annexe le rapport établi en 1988, à destination du Préfet de la Charente Maritime. Ces mortalités ayant rapidement pris de l'ampleur, un dépôt de plainte contre X a été effectué par la Section Régionale de la Conchyliculture. A la suite de quoi, les services d'IFREMER ont été requis par la Gendarmerie Nationale (Brigade de Marennes) le 10 juin 1992, pour...

An evaluation of surface micro- and mesoplastic pollution in pelagic ecosystems of the Western Mediterranean Sea
Provedor de dados: 5
Autores: Faur, Florian; Saini, Camille; Potter, Gael; Galgani, Francois; De Alencastro, Luiz Felippe; Hagmann, Pascal.
This study examines the distribution, abundance and characteristics of surface micro- and mesoplastic debris in the Western Mediterranean Sea. 41 samples were collected in 2011 (summer) and 2012 (summer). Results, firstly, revealed that micro- (&lt;5mm) and mesoplastic debris were widely and uniformly distributed in this area with average concentrations of 130,000 parts/km(2) and 5700 parts/km(2), respectively. Importantly, a strong correlation between micro- and mesoplastic concentrations was identified. Secondly, a classification based on the shape and appearance of microplastics indicated the predominant presence of fragments (73 %) followed by thin films (14 %). Thirdly, the average mass ratio of microplastic to dry organic matter has been measured at...

Circular economy measures to keep plastics and their value in the economy, avoid waste and reduce marine litter
Provedor de dados: 5
Autores: Ten Brink, Patrick; Schweitzer, Jean-pierre; Watkins, Emma; Janssens, Charlotte; De Smet, Michiel; Leslie, Heather; Galgani, Francois.
We live in the plastic age (the “plasticene”), producing over 300 million tonnes (mt) of plastic every year globally, 5–15 mt of which flow into already polluted oceans. Plastic remains a key material in the global economy, but low rates of collection, reuse and recycling, emissions of microplastic from product wear and tear, and often insufficient disposal measures are leading to far-reaching environmental, health, social and economic impacts. The costs of inaction are unacceptably high. Globally there is a growing recognition of the need to address marine litter and rethink our approach to plastics and plastic packaging within the economy. Measures that enable a transition to a circular economy can avoid waste and reduce marine litter, and contribute to...

A large scale study of trace metal contamination (Hg, Cd, Pb and Ni) by means of caged mussels Mytilus galloprovincialis was undertaken along the coastal waters of the Western Mediterranean Sea within the context of the MYTILOS project. Individual mussels from an homogeneous population (shell size 50 +/- 5 mm) obtained from an aquaculture farm were consecutively caged and deployed at 123 sites located in the Alboran, North-Western, South-Western and Tyrrhenian sub-basins for 12 weeks (April-July) in 2004, 2005 and 2006. After cage recoveries, both the metal content in the whole mussel tissue and the allometric parameters were measured. Statistical analysis of the datasets showed significant differences in concentrations between sub-basins for some metals...

Provedor de dados: 5
Autores: Gago, Jesus; Henry, Maryvonne; Galgani, Francois.
This paper examines the presence and distribution of plastic particles in waters off the NW Spanish Atlantic coast. A pilot sampling program was initiated in 2013 to study the presence of plastic particles in surface waters. A total of 41 neuston samples were collected using a manta trawl fitted with a 333 μm mesh (21 samples in 2013 and 20 samples in 2014). Several types of plastic particles were observed in 95% of the stations. A total of 1463 plastic microparticles (&lt;5 mm; mps) and 208 mesoparticles (&gt;5 mm and &lt;20 mm; MPS) were counted. Average concentrations recorded were 0.034 ± 0.032 and 0.176 ± 0.278 mps m−2 and 0.005 ± 0.005 and 0.028 ± 0.043 MPS m−2, respectively for 2013 and 2014.

The Mediterranean Sea is greatly affected by marine litter. In this area, research on the impact of plastic debris (including microplastics) on biota, particularly large filter-feeding species such as the fin whale (Balaenoptera physalus), is still in its infancy. We investigated the possible overlap between microplastic, mesoplastic and macrolitter accumulation areas and the fin whale feeding grounds in in a pelagic Specially Protected Area of Mediterranean Importance (SPAMI): the Pelagos Sanctuary. Models of ocean circulation and fin whale potential habitat were merged to compare marine litter accumulation with the presence of whales. Additionally, field data on microplastics, mesoplastics and macrolitter abundance and cetacean presence were...

Sustained observations are required to determine the marine plastic debris mass balance and to support effective policy for planning remedial action. However, observations currently remain scarce at the global scale. A satellite remote sensing system could make a substantial contribution to tackling this problem. Here, we make initial steps towards the potential design of such a remote sensing system by: (1) identifying the properties of marine plastic debris amenable to remote sensing methods and (2) highlighting the oceanic processes relevant to scientific questions about marine plastic debris. Remote sensing approaches are reviewed and matched to the optical properties of marine plastic debris and the relevant spatio-temporal scales of observation to...

Autores: Jorissen, F. J.; Bicchi, E.; Duchemin, G.; Durrieu, J.; Galgani, Francois; Cazes, L.; Gaultier, M.; Camps, R.
In order to assess the possible environmental impact of oily cuttings discharged during oil exploration activities, we studied the benthic foraminiferal faunas in a five-station, 4-km-long sampling transect around a cuttings disposal site at about 670 m depth offshore Angola (W Africa). where drilling activities started 1.5 years before sampling. Living (Rose Bengal stained) and dead foraminiferal faunas were sampled in March 2006. The faunal patterns mirror the spatial distribution of hydrocarbons, which are dispersed into a southeastern direction. Four different areas can be distinguished on the basis of the investigated faunal parameters (density, diversity and species composition of the living fauna, and comparison with subrecent dead faunas).

The dragonet Callionymus lyra, a target species used for evaluation of biological effects of chemical contaminants on French coasts
Provedor de dados: 5
Autores: Burgeot, Thierry; Bocquene, Gilles; Truquet, Philippe; Le Dean, Loic; Poulard, Jean-charles; Dorel, Didier; Souplet, Arnauld; Galgani, Francois.
An oceanographic cruise in 1991 along the English Channel and Atlantic coasts of France indicated the value of dragonet Callionymus lyra Linnaeus, 1758 as a target species for monitoring biological effects. Ethoxyresorufin-O-deethylase measurements in this species provided a first assessment of the effects of hydrocarbons (PCB, PAH, dioxins) on the marine environment. The specific behavior of dragonet was defined by biochemical characterization. Biological data were obtained during 3 additional oceanographic cruises to study changes in the abundance and distribution of the species in the English Channel and the Bay of Biscay. This first assessment, carried out in the context of the National Observation Network, indicated that pollutants do not have...

Molecular cloning of flounder Xp18, a newly identified highly conserved protein mainly expressed in the ovary
Provedor de dados: 5
Autores: Cachot, Jerome; Bultelle, Florence; Drouot, Laurent; Galgani, Francois; Frebourg, Thierry; Leboulenger, François; Danger, Jean-michel.
Screening of a flounder ovary cDNA library with a rainbow trout p53 probe led to the isolation of a p53-unrelated cDNA encoding an unknown 161 amino acid protein. In view of its apparent molecular weight and yet unknown function, the deduced protein was named Xp18. Corresponding orthologous cDNAs or expressed sequence tags have been identified in several species including human, rodents, bovine, chicken and zebrafish and a related cDNA has also been isolated in the fruit fly. Deduced amino acid sequences appeared to be extremely well conserved throughout vertebrate evolution. Structure predictions suggested that Xp 18 may correspond to an integral protein comprising four transmembrane domains. The charged C-termini of all known vertebrate Xp18-like...

Phthalate release from plastic fragments and degradation in seawater
Provedor de dados: 5
Autores: Paluselli, Andrea; Fauvelle, Vincent; Galgani, Francois; Sempere, Richard.
Plastic debris in the environment contain plasticizers, such as phthalates (PAEs), that can be released during plastic aging. Here, two common plastic materials, i.e., an insulation layer of electric cables (polyvinylchloride, PVC-cables) and plastic garbage bag (polyethylene, PE-bags), were incubated in natural seawater under laboratory conditions, and the PAE migration to the seawater phase was studied with varying light and bacterial conditions over a 90-day time course. Free PAEs diluted in seawater were also studied for bacterial degradation. Our results showed that, within the first month of incubation, both plastic materials significantly leached out PAEs in surrounding water. We found that di-isobutyl phthalate (DiBP) and di-n-butyl phthalate...

Autores: Paluselli, Andrea; Aminot, Yann; Galgani, Francois; Net, Sopheak; Sempere, Richard.
Phthalate acid esters (PAEs) which are mainly anthropogenic molecules with endocrine disrupting effects in animals and humans, have been detected in terrestrial and aquatic environments. However, little is known about their distribution in the Mediterranean Sea, mainly because of analytical difficulties and the high possibility of ambient sample contamination. Here, we report the optimization of an existing protocol for the determination of PAEs in seawater and freshwater samples, as well as the first estimation of the source and distribution of phthalates acid esters (PAEs) in coastal waters from the NW Mediterranean Sea. By passing 1 L of sample through glass cartridges packed with 200 mg of Oasis HLB and eluted with 6 mL of ethyl acetate, the recoveries...

Anthropogenic litter is present in all marine habitats, from beaches to the most remote points in the oceans. On the seafloor, marine litter, particularly plastic, can accumulate in high densities with deleterious consequences for its inhabitants. Yet, because of the high cost involved with sampling the seafloor, no large-scale assessment of distribution patterns was available to date. Here, we present data on litter distribution and density collected during 588 video and trawl surveys across 32 sites in European waters. We found litter to be present in the deepest areas and at locations as remote from land as the Charlie-Gibbs Fracture Zone across the Mid-Atlantic Ridge. The highest litter density occurs in submarine canyons, whilst the lowest density can...

Test écotoxicologique sur microalgues et lecteur de plaques : mesures d'activités enzymatiques sur cellules in vivo. Application à l'évaluation de la qualité du milieu
Provedor de dados: 5
Autores: Gilbert, Franck; Galgani, Francois.
A new method for the assessment of several contaminant effects on marine microalgae (Tetraselmis suesica, Skeletonema costatum) has been developped. The method is based on the measure of cells esterase activity using a fluorimetric stain, fluorescein diacetate (FDA). The experiments are performed in microplates using a fluorimetric microplate reader. The different steps of the experiments and the data processing are controlled by an original specific software. Application of the system for rapid ecotoxicological tests (determination of LC 50) and for assessment of environment quality by observation of water samples are proposed.

Autores: Claro, F; Fossi, Mc; Ioakeimidis, C; Baini, M; Lusher, Al; Mc Fee, W; Mcintosh, Rr; Pelmatti, T; Sorce, M; Galgani, Francois; Hardesky, Bd.
Adverse impacts of marine litter is documented on &gt;1400 species, including marine megafauna (fish, birds, sea turtles and mammals). The primary impacts include ingestion and entanglement, and there is increasing concern about chemical contamination via ingestion. Numerous survey approaches and monitoring programs have been developed and implemented around the world. They may aim to provide data about parameters such as species distribution and interactions with anthropogenic activities. During the Sixth International Marine Debris Conference, a session was dedicated to the tools and constraints in monitoring interactions between litter and megafauna. In the present paper, we summarize 7 case studies which discuss entanglement and ingestion including...

Minerals as additives for decreasing the toxicity of Mediterranean contaminated dredged sediments
Provedor de dados: 5
Autores: Mamindy-pajany, Y.; Galgani, Francois; Romeo, M.; Hurel, C.; Marmier, N.
The management of dredged sediments is a priority issue in the Mediterranean sea where sediments are historically polluted. The aims of this study were to evaluate the toxicity of port sediment samples and the effect of three mineral additives (hematite, zerovalent iron (ZVI) and natural zeolite (NZ)) on sediment elutriate toxicity. Four sediments (A, B, C and D) were provided by port authorities after composting procedure; particle size, particulate organic carbon, metals and organic pollutants (TBT, PAHs, PCBs) were determined in whole sediments. Elutriates from these composted sediments were analyzed by determining toxicity level using oyster (Crassostrea gigas) larvae bioassay, metal and dissolved organic carbon concentrations. Toxicity, measured on...

Autores: Alexy, Pavol; Anklam, Elke; Emans, Ton; Furfari, Antonino; Galgani, Francois; Hanke, Georg; Koelmans, Albert; Pant, Rana; Saveyn, Hans; Sokull Kluettgen, Birgit.
This paper identifies knowledge gaps on the sustainability and impacts of plastics and presents some recommendations from an expert group that met at a special seminar organised by the European Commission at the end of 2018. The benefits of plastics in society are unquestionable, but there is an urgent need to better manage their value chain. The recently adopted European Strategy for Plastics stressed the need to tackle the challenges related to plastics with a focus on plastic litter including microplastics. Microplastics have been detected mainly in the marine environment, but also in freshwater, soil and air. Based on today’s knowledge they may also be present in food products. Although nanoplastics have not yet been detected, it can be assumed that...

Monitoring of pollutant biochemical effects on marine organisms of the french coasts
Provedor de dados: 5
Autores: Galgani, Francois; Bocquene, Gilles; Truquet, Philippe; Burgeot, Thierry; Chiffoleau, Jean-francois; Claisse, Didier.
The establishment of a network to assess pollutant effects is a current concern of international bodies such as the North Sea Task Force, the International Council for the Exploration of the Sea and the Intergovernmental Oceanographic Commission. With respect to the French coasts, three major considerations have been defined : the choice of monitoring areas ; the determination of a target species according to different criteria such as wide distribution, limited migration and contact with pollutant-rich sediments; and the selection of suitable parameters. This paper concerns the strategy adopted for the French coast. Ethoxyresorufin-O-deethylase, a specific cytochrome P450-dependent monooxygenase, measured by a simple microplate assay, was selected as an...

Background: Pollution – unwanted waste released to air, water, and land by human activity – is the largest environmental cause of disease in the world today. It is responsible for an estimated nine million premature deaths per year, enormous economic losses, erosion of human capital, and degradation of ecosystems. Ocean pollution is an important, but insufficiently recognized and inadequately controlled component of global pollution. It poses serious threats to human health and well-being. The nature and magnitude of these impacts are only beginning to be understood. Goals: (1) Broadly examine the known and potential impacts of ocean pollution on human health. (2) Inform policy makers, government leaders, international organizations, civil society, and the...

Marine litter within the European Marine Strategy Framework Directive
Provedor de dados: 5
Autores: 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...

Whilst both plastic production and inputs at sea have increased since the 1950s, several modelling studies predict a further increase in the coming years in these respective quantities. We compiled scientific literature on trends in marine litter, consisting largely of plastic and microplastics in the ocean, understanding that monitoring programs or assessments for these aspects are varied, frequently focusing on limited components of the marine environment in different locations, and covering a wide spectrum of marine litter types, with limited standardization. Here we discuss how trends in the amounts of litter in the marine environment can be compared with the information provided by models. Increasing amounts of plastic are found in some regions,...

Microplastics in Seawater: Recommendations from the Marine Strategy Framework Directive Implementation Process
Provedor de dados: 5
Autores: Gago, Jesus; Galgani, Francois; Maes, Thomas; Thompson, Richard C.
Microplastic litter is a pervasive pollutant present in marine systems across the globe. The legacy of microplastics pollution in the marine environment today may remain for years to come due to the persistence of these materials. Microplastics are emerging contaminants of potential concern and as yet there are few recognized approaches for monitoring. In 2008, the EU Marine Strategy Framework Directive (MSFD, 2008/56/EC) included microplastics as an aspect to be measured. Here we outline the approach as discussed by the European Union expert group on marine litter, the technical Subgroup on Marine litter (TSG-ML), with a focus on the implementation of monitoring microplastics in seawater in European seas. It is concluded that harmonization and coherence...

Accumulation and fragmentation of plastic debris in global environments
Provedor de dados: 5
Autores: Barnes, David K. A.; Galgani, Francois; Thompson, Richard C.; Barlaz, Morton.
One of the most ubiquitous and long-lasting recent changes to the surface of our planet is the accumulation and fragmentation of plastics. Within just a few decades since mass production of plastic products commenced in the 1950s, plastic debris has accumulated in terrestrial environments, in the open ocean, on shorelines of even the most remote islands and in the deep sea. Annual clean-up operations, costing millions of pounds sterling, are now organized in many countries and on every continent. Here we document global plastics production and the accumulation of plastic waste. While plastics typically constitute approximately 10 per cent of discarded waste, they represent a much greater proportion of the debris accumulating on shorelines. Mega- and...

An intercalibration exercise on the characterisation of microplastics in marine sediment and water samples was carried out among five laboratories involved in the implementation of the Marine Strategy Framework Directive (MSFD) in their country. The samples were prepared by mixing cleaned natural sediment and sea water with microplastics sets made of particles of various polymers, shapes and colours. Overall, the errors on total counts were under 25% in absolute value. The risk of non-detection and loss of particles is greater than the risk of contamination during sample analysis. Significant differences are observed among particle types. It appears difficult to obtain reliable and comparable data on the colour of microplastics. A comparison of the errors...

On June 2013 a workshop at the University of Siena (Italy) was organized to review current knowledge and to clarify what is known, and what remains to be investigated, concerning plastic litter in the sea. The content of the workshop was designed to contribute further to the European Marine Strategy Framework Directive (MSFD) following an inaugural workshop in 2012. Here we report a number of statements relevant to policymakers and scientists that was overwhelming agreement from the participants. Many might view this as already providing sufficient grounds for policy action. At the very least, this early warning of the problems that lie ahead should be taken seriously, and serve as a stimulus for further research.

During the Bremerhaven Workshop an improved, fast and easy method for the determination of ethoxyresorufin-O-deethylase (EROD) activity in dab Limanda limanda liver was tested. The improvement involved the use of a 12500 x g supernatant instead of the microsomal fraction, thus omitting the need for long ultra-centrifugations which cannot be carried out aboard a research vessel. EROD activities in the 12 500 x g supernatant and in the microsomal suspension were well correlated. Despite its disadvantages of lower specific EROD activity, higher minimum detection limit and higher analytical variance, the 12 500 x g supernatant was used for further analysis. EROD activity in dab liver showed a spatial trend corresponding to a pollution gradient in the German...

The dominance and persistence of plastic debris in the marine environment are well documented. No information exists in respect to their lifespan in the marine environment. Nevertheless, the degradation potential of plastic litter items remains a critical issue for marine litter research. In the present study, polyethylene terephthalate bottles (PETs) collected from the submarine environment were characterized using ATR-FTIR in respect to their degradation potential attributed to environmental conditions. A temporal indication was used as indicative to the years of presence of the PETs in the environment as debris. PETs seem to remain robust for approximately fifteen years. Afterwards, a significant decrease of the native functional groups was recorded;...

Current dynamics in the Strait of Bonifacio (south Corsica) were investigated at a small scale during the STELLAMARE1 multidisciplinary cruise in summer 2012, using in situ measurements and modeling data. The Strait of Bonifacio is a particularly sensitive marine area in which specific conservation measures have been taken to preserve the natural environment and wild species. Good knowledge of the hydrodynamics in this area is essential to optimize the Marine Protected Area's management rules. Therefore, we used a high-resolution model (400 m) based on the MARS3D code to investigate the main flux exchanges and to formulate certain hypotheses about the formation of possible eddy structures. The aim of the present paper is first to synthetize the results...

Marine litter is a growing problem for environmental and human health and policies have included monitoring as an important tool to evaluate both trends and the efficiency of reduction measures. The Marine Strategy Framework Directive is the main driver in Europe for the monitoring of the marine environment; it has included the evaluation of marine litter in order to support policies and achieve good environmental status. This assessment depends on the availability of robust, homogeneous data-sets at the European scale. A data management plan for marine litter has been developed at European level within the existing EMODnet network to collect, homogenise and provide access to standardised data-sets and data products that may be used as a basis for marine...

Human behavior and the intensive use of plastic, combined with poor performance of management systems have led to a massive accumulation of plastic debris in the marine environment, accounting for 50 to 80 % of all marine litter. Their distribution, their fate, their degradation and their impacts stem directly from their composition and use properties. This article reviews knowledge and describes the main scientific, environmental and socio-economic issues, as well as the possible solutions needed to manage an environmental problem that has become global.

Proteolytic enzymes of hepatopancreas of six species of peneids (Penaeus kerathurus, P. japonicus, P. monodon, P. stylirostris, P. merguiensis and P. vannamei ) have been studied. Some of their physiological variations have been characterised. Increase in acclimation temperature of crustaceans enhances increase of specific activities of proteases. Variations of salinity does not modify specific activities, nor quantities of trypsin, nor electrophoretic patterns of these different proteases.

Marine litter is one of the main sources of anthropogenic pollution in the marine ecosystem, with plastic representing a global threat. This paper aims to assess the spatial distribution of plastic macro-litter on the seafloor, identifying accumulation hotspots at a northern Mediterranean scale. Density indices (items km–2) from the MEDITS trawl surveys (years 2013-2015) were modelled by generalized additive models using a Delta-type approach and several covariates: latitude, longitude, depth, seafloor slope, surface oceanographic currents and distances from main ports. To set thresholds for the identification of accumulation areas, the percentiles (85th, 90th and 95th) of the plastic spatial density distribution were computed on the raster data. In the...

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...

Autores: Galgani, Francois; Loubersac, Lionel.
This text presents the general problem of nuisance and pollution created by macro-waste at sea. We clarify three main types of pollution: that of coasts, that of the sea bed and that of the open sea. The article leans on scientific data: report of the state of contamination of the coasts of France by macro waste (1982), results of works and oceanographic sea bed observation campaigns, evaluation of the contamination by micro-plastics floating on surface and concentrating in the big oceanic gyres. A paragraph is dedicated to the impacts on the ecosystems, an other one on the taken measures to fight against those macro-waste. The specific case of New Caledonia is not forgotten and in conclusion we underline the necessity of an education of the populations in...

Megafauna of vulnerable marine ecosystems in French mediterranean submarine canyons: Spatial distribution and anthropogenic impacts
Provedor de dados: 5
Autores: Fabri, Marie-claire; Pedel, Laura; Beuck, L.; Galgani, Francois; Hebbeln, D.; Freiwald, A.
Vulnerable Marine Ecosystems (VME) in the deep Mediterranean Sea have been identified by the General Fisheries Commission for the Mediterranean as consisting of communities of Scleractinia (Lophelia pertusa and Madrepora oculata), Pennatulacea (Funiculina quadrangularis) and Alcyonacea (Isidella elongata). This paper deals with video data recorded in the heads of French Mediterranean canyons. Quantitative observations were extracted from 101 video films recorded during the MEDSEACAN cruise in 2009 (Aamp/Comex). Qualitative information was extracted from four other cruises (two Marum/Comex cruises in 2009 and 2011 and two Ifremer cruises in 1995 and 2010) to support the previous observations in the Cassidaigne and Lacaze-Duthiers canyons. All the species,...

Microplastics in sediments: A review of techniques, occurrence and effects
Provedor de dados: 5
Autores: Van Cauwenberghe, Lisbeth; Devriese, Lisa; Galgani, Francois; Robbens, Johan; Janssen, Colin R.
Microplastics are omnipresent in the marine environment and sediments are hypothesized to be major sinks of these plastics. Here, over 100 articles spanning the last 50 year are reviewed with following objectives: (i) to evaluate current microplastic extraction techniques, (ii) to discuss the occurrence and worldwide distribution of microplastics in sediments, and (iii) to make a comprehensive assessment of the possible adverse effects of this type of pollution to marine organisms. Based on this review we propose future research needs and conclude that there is a clear need for a standardized techniques, unified reporting units and more realistic effect assessments.

Seafloor litter from the continental shelf and canyons in French Mediterranean Water: Distribution, typologies and trends
Provedor de dados: 5
Autores: Gerigny, Olivia; Brun, Melanie; Fabri, Marie-claire; Tomasino, Corinne; Le Moigne, Morgan; Jadaud, Angelique; Galgani, Francois.
Seafloor litter has been studied both on the continental shelves (by trawling during 24 years) and in canyons (by ROV) of the French Mediterranean sea Water (FMW). On the continental shelf, mean densities range from 49.63 to 289.01 items/km2. The most abundant categories were plastic, glass/ceramics, metals and textiles. Trend analysis shows a significant increase in plastic quantities during the study period. Plastics accumulate at all depths, with heavier items being found in deeper areas, while the continental slope-break appears as a clean area. The spatial distribution of litter revealed the influence of geomorphologic factors, anthropic activities, shipping route, river inputs. All the canyons are affected by debris but coastal canyons (Ligurian Sea...

PERSEUS project aims to identify the most relevant pressures exerted on the ecosystems of the Southern European Seas (SES), highlighting knowledge and data gaps that endanger the achievement of SES Good Environmental Status (GES) as mandated by the Marine Strategy Framework Directive (MSFD). A complementary approach has been adopted, by a meta-analysis of existing literature on pressure/impact/knowledge gaps summarized in tables related to the MSFD descriptors, discriminating open waters from coastal areas. A comparative assessment of the Initial Assessments (IAs) for five SES countries has been also independently performed. The comparison between meta-analysis results and IAs shows similarities for coastal areas only. Major knowledge gaps have been...

The boundary current role on the transport and stranding of floating marine litter: The French Riviera case
Provedor de dados: 5
Autores: Ourmieres, Yann; Mansui, Jeremy; Molcard, Anne; Galgani, Francois; Poitou, Isabelle.
The aim of the present study is to evidence the role of a boundary current and meteorological conditions in the transport and stranding of floating marine debris. The used data are from a beach survey and an inter-annual unique effort of marine debris sightings along the French Riviera in the North-Western Mediterranean region. Offshore data have been collected during oceanic cruises while beach surveys were performed around Antibes city. Debris were found on 97% of the ocean transects, with a large spatial and temporal variability, showing contrasted areas of low (~ 1 item/km2) and of high (&gt; 10 items/km2) debris densities. Results suggest that the debris spatio-temporal distribution is related to the Northern current (NC) dynamics, the regional...

In order to evaluate the contamination levels in the Western Mediterranean basin, the active mussel watch methodology has been applied. This methodology consists of mussel transplantation (Mytilus galloprovincialis) from non impacted areas to selected coastal areas, characterised by potential impact from the continent due to contaminating sources. The areas of interest were selected along the entire coastal development of the Western Mediterranean sea, 122 sites in total. The time of mussel caging exposure was 12 weeks. The project was co-financed in the frame of the Interreg IIIB Meddoc Programme, aimed at determining the overall chemical quality of the Mediterranean sea, consistent with the Water Framework Directive 2000/60.

An integrated approach using biomarkers and contaminant levels in mussels Mytilus galloprovincialis L was employed to assess chemical contamination in Greek coastal waters within the framework of the MYTIMED program. Biomarkers (metallothioneins, glutathione S-transferase, catalase, acetylcholinesterase and RNA:DNA ratio) have been previously described in mussels caged at 14 sites in coastal areas influenced by different types of anthropogenic activities. This study applied a biomarker index, the Integrated Biomarker Response (IBR) to summarize biomarker responses and relate stress levels to concentrations of organochlorine compounds (PCBs, DDTs), polycyclic aromatic hydrocarbons (PAHs), and metals (Cu, Ni, Fe, Zn) measured in the mussel tissues. The IBR...

Multixenobiotic resistance protein expression in Mytilus edulis, M-galloprovincialis and Crassostrea gigas from the French coasts
Provedor de dados: 5
Autores: Minier, C; Moore, M; Galgani, Francois; Claisse, Didier.
Multixenobiotic resistance (MXR) is a membrane-transport mechanism that allows organisms to exclude many compounds from their cells and tissues. It is thus a first line of defence against a variety of toxic compounds. Since mussels and oysters possess MXR proteins, an analysis of the expression level of these membrane-transporters has been conducted in relation to their body burden of some major environmental contaminants. Mussels Mytilus edulis and M. galloprovincialis and the oyster Crassostrea gigas were sampled from a total of 43 sites along the French coasts. High expression levels were found in animals from the major French estuaries (Seine, Loire and Gironde), at a few sites in Brittany and in nearly all sites from the Mediterranean mainland coasts....

The seafloor covers some 70% of the Earth's surface and has been recognized as a major sink for marine litter. Still, litter on the seafloor is the least investigated fraction of marine litter, which is not surprising as most of it lies in the deep sea, i.e. the least explored ecosystem. Although marine litter is considered a major threat for the oceans, monitoring frameworks are still being set up. This paper reviews current knowledge and methods, identifies existing needs, and points to future developments that are required to address the estimation of seafloor macrolitter. It provides background knowledge and conveys the views and thoughts of scientific experts on seafloor marine litter offering a review of monitoring and ocean modeling techniques....

Plastics and other artificial materials pose new risks to the health of the ocean. Anthropogenic debris travels across large distances and is ubiquitous in the water and on shorelines, yet, observations of its sources, composition, pathways, and distributions in the ocean are very sparse and inaccurate. Total amounts of plastics and other man-made debris in the ocean and on the shore, temporal trends in these amounts under exponentially increasing production, as well as degradation processes, vertical fluxes, and time scales are largely unknown. Present ocean circulation models are not able to accurately simulate drift of debris because of its complex hydrodynamics. In this paper we discuss the structure of the future integrated marine debris observing...

Autores: Schmidt, Natascha; Thibault, Delphine; Galgani, Francois; Paluselli, Andrea; Sempere, Richard.
Between 2014 and 2016 a total of 43 microplastic samples were collected at six sampling stations in the eastern section of the Gulf of Lion (located in the northwestern Mediterranean Sea), as well as upstream of the Rhône River. Microplastics were found in every sample with highly variable concentrations and masses. Concentrations ranged from 6 · 103 items km−2 to 1 · 106 items km−2 (with an average of 112 · 103 items km−2), and mass ranged from 0.30 g km−2 to 1018 g km−2 DW (mean 61.92 ± 178.03 g km−2). The samples with the highest and lowest microplastic count originate both from the Bay of Marseille. For the Bay of Marseille, it is estimated that the total microplastic load consist of 519 · 103 –101 · 106 items weighing 0.07–118 kg. Estimations for...

Autores: Collignon, Amandine; Hecq, Jean-henri; Galgani, Francois; Collard, France; Goffart, Anne.
The annual variation in neustonic plastic particles and zooplankton was studied in the Bay of Calvi (Corsica) between 30 August 2011 and 7 August 2012. Plastic particles were classified into three size classes, small microplastics (0.2–2 mm), large microplastics (2–5 mm) and mesoplastics (5–10 mm).  74% of the 38 samples contained plastic particles of varying composition: e.g. filaments, polystyrene, thin plastic films. An average concentration of 6.2 particles/100 m2 was observed. The highest abundance values (69 particles/100 m2) observed occurred during periods of low offshore wind conditions. These values rose in the same order of magnitude as in previous studies in the North Western Mediterranean.  The relationships between the abundance values of the...

The Marine Strategy Framework Directive (MSFD), introduced in June 2008, was adopted to achieve a Good Environmental Status (GES) in the EU's marine waters and to protect resources of socio-economic interest. The MSFD exerts to the marine area over which a Member State exercises jurisdictional rights in accordance with the United Nations Convention on the Law of the Sea (UNCLOS), including the deep-sea waters, seafloor and sub-seafloor of the Exclusive Economic Zones (EEZ). However, currently the MSFD focuses on coastal habitats and the shallow-water seafloor to the detriment of the deeper habitats. Despite the huge dimension of the deep sea (below 200 m of depth) covering more than 65% of the Earth's surface and including &gt;95% of the global biosphere,...

Automating the characterisation of beach microplastics through the application of image analyses
Provedor de dados: 5
Autores: Gauci, Adam; Deidun, Alan; Montebello, John; Abela, John; Galgani, Francois.
Four sandy beaches on the island of Malta in the Central Mediterranean were regularly sampled for Large MicroPlastic (LMP) particles having a diameter between 1 mm and 5 mm, at stations located at the waterline and 10 m inshore. The 10975 extracted LMP particles were characterised (dimensions, surface roughness, colour) through unaided visual observation, microscopic analyses, and an algorithm developed within the current study. Two-thirds of the isolated particles were smooth and the majority of these belonged to the grey-white colour category, with a low degree of opaqueness and discolouration, and a high degree of transparency, suggesting that these were dominated by low-density polyethylene LMPs. Conflicting evidence concerning the relative residence...

Plastic pollution is ubiquitous throughout the marine environment, yet estimates of the global abundance and weight of floating plastics have lacked data, particularly from the Southern Hemisphere and remote regions. Here we report an estimate of the total number of plastic particles and their weight floating in the world's oceans from 24 expeditions (2007-2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N=680) and visual survey transects of large plastic debris (N=891). Using an oceanographic model of floating debris dispersal calibrated by our data, and correcting for wind-driven vertical mixing, we estimate a minimum of 5.25 trillion particles weighing 268,940 tons.

The toxicity of composted sediments from Mediterranean ports evaluated by several bioassays
Provedor de dados: 5
Autores: Mamindy-pajany, Yannick; Hamer, Bojan; Romeo, Michele; Geret, Florence; Galgani, Francois; Durmisi, Emina; Hurel, Charlotte; Marmier, Nicolas.
This work investigates the ecotoxicological evaluation of contaminated dredged sediments from French Mediterranean navy harbour (A), commercial port (B) and two composite specimens (C) and (D) coming from the mixture of A and B with other port sediments. The toxicity of elutriates from these sediments is estimated using embryo-toxicity test. Microtox (R) solid phase test, LuminoTox, phytotoxicity tests and genotoxicity test. Bioassay responses are not clearly correlated with chemical contamination in the whole sediment and vary as a function of tested organisms. The highest contaminated samples (A and C) are almost always more toxic than the less contaminated samples (B and D). Among composite sediments, the mixture effect with other sediments is not...

Autores: Burgeot, Thierry; Bocquene, Gilles; Porte, C; Dimeet, Joel; Santella, Rm; Garcia De La Parra, L.m.; Pihol-leszkowicz, A.; Raoux, C.; Galgani, Francois.
Several bioindicators were used to evaluate the biological and genotoxic effects of marine pollutants near large coastal cities in the northwestern part of the Mediterranean Sea. Three target species of teleosts were selected: red mullet Mullus barbatus and 2 types of comber (Serranus hepatus and S. cabrilla). Induction of ethoxyresorufin-O-deethylase (EROD) activity specific for polycyclic aromatic hydrocarbons (PAH) and polychlorinated biphenyls (PCB) was measured in the livers of the fish, and inhibition of acetylcholinesterase (AChE) by organophosphorus insecticides and carbamates was measured in their muscle tissues. Maximal EROD activities (16.8 +/- 2.7 to 19.4 +/- 4.2 pmol min(-1) mg protein(-1)) recorded in red muller near Barcelona (Spain),...

Circular economy measures to keep plastics and their value in the economy, avoid waste and reduce marine litter
Provedor de dados: 5
Autores: Ten Brink, Patrick; Schweitzer, Jean-pierre; Watkins, Emma; De Smet, Michel; Leslie, Heather; Galgani, Francois.
We live in the plastic age (the “plasticene”), producing over 300 million tonnes (mt) of plastic every year globally, 5-15 mt of which flow into already polluted oceans. Plastic remains a key material in the global economy, but low rates of collection, reuse and recycling, emissions of microplastic from product wear and tear, and often insufficient disposal measures are leading to far-reaching environmental, health, social and economic impacts. The costs of inaction are unacceptably high. Globally there is a growing recognition of the need to address marine litter and rethink our approach to plastics and plastic packaging within the economy. Measures that enable a transition to a circular economy can avoid waste and reduce marine litter, and contribute to...

Does coastal lagoon habitat quality affect fish growth rate and their recruitment? Insights from fishing and acoustic surveys
Provedor de dados: 5
Autores: Brehmer, Patrice; Laugier, Thierry; Kantoussan, J.; Galgani, Francois; Mouillot, D.
Ensuring the sustainability of fish resources necessitates understanding their interaction with coastal habitats, which is becoming ever more challenging in the context of ever increasing anthropogenic pressures. The ability of coastal lagoons, exposed to major sources of disturbance, to provide resources and suitable habitats for growth and survival of juvenile fish is especially important. We analysed three lagoons with different ecological statuses and habitat quality on the basis of their eutrophication and ecotoxicity (Trix test) levels. Fish abundances were sampled using fishing and horizontal beaming acoustic surveys with the same protocols in the same year. The relative abundance of Anguilla anguilla, Dicentrarchus labrax or the Mugilidae group was...

Risk assessment reveals high exposure of sea turtles to marine debris in French Mediterranean and metropolitan Atlantic waters
Provedor de dados: 5
Autores: Darmon, Gaelle; Miaud, Claude; Claro, Francoise; Doremus, Ghislain; Galgani, Francois.
Debris impact on marine wildlife has become a major issue of concern. Mainy species have been identified as being threatened by collision, entanglement or ingestion of debris, generally plastics, which constitute the predominant part of the recorded marine debris. Assessing sensitive areas, where exposure to debris are high, is thus crucial, in particular for sea turtles which have been proposed as sentinels of debris levels for the Marine Strategy Framework Directive and for the Unep-MedPol convention. Our objective here was to assess sea turtle exposure to marine debris in the 3 metropolitan French fronts. Using aerial surveys performed in the Channel, the Atlantic and the Mediterranean regions in winter and summer 2011–2012, we evaluated exposure areas...

As part of the AMARE project, the main purpose of this report is to provide advice and practical guidance, for establishing programmes to monitor and assess the distribution and abundance of marine litter in MPAs. The present document build on relevant existing monitoring and assessment practices in the Mediterranean, such as the existing monitoring practices in UNEP/MAP and within the Marine Strategy Framework Directive. The proposed strategy (defining the sampling scheme, the environmental compartment to monitor and the protocols to be used) is also based on recommendations of the UN GESAMP report on monitoring marine litter (GESAMP, 2019). In addition, it is based on the experience of ongoing monitoring and assessment activities under various scientific...

Global Distribution, Composition and Abundance of Marine Litter
Provedor de dados: 5
Autores: Galgani, Francois; Hanke, Georg; Maes, Thomas.
Marine debris is commonly observed everywhere in the oceans. Litter enters the seas from both land-based sources, from ships and other installations at sea, from point and diffuse sources, and can travel long distances before being stranded. Plastics typically constitute the most important part of marine litter sometimes accounting for up to 100 % of floating litter. On beaches, most studies have demonstrated densities in the 1 item m−2 range except for very high concentrations because of local conditions, after typhoons or flooding events. Floating marine debris ranges from 0 to beyond 600 items km−2. On the sea bed, the abundance of plastic debris is very dependent on location, with densities ranging from 0 to &gt;7700 items km−2, mainly in coastal...

Marine animal forests as useful indicators of entanglement by marine litter
Provedor de dados: 5
Autores: Galgani, Francois; Pham, Christopher K.; Claro, Francoise; Consoli, Pierpaolo.
Entanglement of marine fauna is one of the principal impacts of marine litter, with an incidence that can vary strongly according to regions, the type and the quantity of marine litter. On the seafloor, areas dominated by sessile suspension feeders, such as tropical coral reefs or deep-sea coral and sponge aggregations, have been termed “animal forests” and have a strong potential to monitor the temporal and spatial trends of entanglement by marine litter, especially fishing gears. Several characteristics of these organisms represent advantages while avoiding constraints and bias. Biological constraints and logistical aspects, including tools, are discussed to better define a strategy for supporting long-term evaluation of accumulation and entanglement of...

Marine pollution: Let us not forget beach sand
Provedor de dados: 5
Autores: Galgani, Francois; Ellerbrake, Katrin; Fries, Elke; Goreux, Chantal.
Background: Assessing the chemical or bacterial contamination in marine waters and sediments is a very common approach to evaluate marine pollution and associated risks. However, toxicity and organic pollution of beach sands have not yet been considered, except in adjacent waters. In the present study, the toxicity and the chemical contamination of natural beach sands collected 20 m from the shoreline at two sites located on the Mediterranean Sea (Marseille and La Marana, Corsica) were studied. Results: Up to 16.93% (net percentage) abnormal or dead larvae was observed in elutriates prepared from the urban beach sand sample (Marseille); no significant toxicity was observed in the sample collected from the reference beach in La Marana. Results of Fourier...

Comparison of benthic foraminifera and macrofaunal indicators of the impact of oil-based drill mud disposal
Provedor de dados: 5
Autores: Denoyelle, Marieva; Jorissen, Frans J.; Martin, Daniel; Galgani, Francois; Mine, Jacques.
We compare foraminifera and macrofauna as bio-indicators of oil-based drill mud disposal site off Congo. The most polluted sites are characterized by poor faunas, dominated by some very tolerant taxa. Slightly further from the disposal site, there is an area with strongly increased densities, heavily dominated by opportunistic taxa. Still further, macrofauna appears to be similar to that at the reference area, but the foraminiferal meiofauna still suggests a slight environmental perturbation. The foraminiferal FIEI index, based on the species distribution in the study area, appears to be more discriminative than the macrofaunal ITI index, based on a priori definitions of the trophic guilds of the various taxa. Our comparative approach allows us to point...
