How to assess fin damage in rainbow trout, Oncorhynchus mykiss?
Provedor de dados: 5
Autores: Person, Jeannine; Le Bayon, Nicolas; Gros, Sylvie.
Fin condition was examined in 100-500 g hatchery-reared rainbow trout sampled in a large range of environmental conditions of
an experimental farm. A method that is simple to use, requires little training, and does not need costly sophisticated equipment or
reference to a model is proposed to assess fin erosion (defined as a decrease in size and profile alteration of fins). A procedure to
reliably measure the length of the longest ray present in two selected fins (dorsal and pectoral) is described. Fin general profile is
assessed using five levels of erosion based on the precise rank of intact or eroded rays to limit subjective bias. The suitability of
the two descriptors of fin erosion under laboratory, farm or field conditions is discussed.

Direct assessment of anchovy by the PELGAS04 acoustic survey
Provedor de dados: 5
Autores: Masse, Jacques; Beillois, Pierre; Duhamel, Erwan.
An acoustic survey was carried out in the bay of Biscay from April 27th to May 25th on board the French research vessel
Thalassa. The objective of PELGAS04 survey was to study the abundance and distribution of pelagic fish in the Bay of Biscay.
The target species were mainly sardine and anchovy but had to be considered in a multi-specific context. The results have to be
used during ICES working groups in charge of the assessment of sardine, anchovy, mackerel and horse mackerel and in the frame
of the Ifremer fisheries ecology program "resources variability".

The present paper aims at identifying and assessing indicators of the effects of Marine Protected Areas (MPAs) in coral reef
regions, based on a bibliography review in ecology, economics and social sciences. First the various effects Studied within each of
these domains and the variables used to measure them were censused. Potential ecological indicators were assessed through their
link with the question used (here termed "relevance") and their "effectiveness" which encompasses the issues of precision,
accuracy and statistical power. Relevance and effectiveness were respectively measured by the frequency of use of each indicator
and the proportion of significant results in the reviewed articles. For social and economic effects, the approach was not...

Environmental constraints and aquaculture development
Provedor de dados: 5
Autores: Paquotte, Philippe; Bailly, Denis.
Aquaculture is an economic activit y which is characterised by a great dependence on environmental conditions. Therefore,
aquaculture development is subdued to institutional context which defines the rules for use and conservation of natural resources.
This paper analyses the impact of marine environment regulations on economic operating of aquaculture enterprises and on
industrial d ynamics. Because aquaculture enterprises use common goods, an economic approach of aquaculture has to take into
account not only the relations between enterprises and environment, but also the relations between the enterprises themselves,
through production externalities. In this study, several economic tools are considered in order to incite enterprises to integrate parr

Comparative foraging ecology and ecological niche of a superabundant tropical seabird: the sooty
tern Sterna fuscata in the southwest Indian Ocean
Provedor de dados: 5
Autores: Jaquemet, S; Potier, M; Cherel, Y; Kojadinovic, J; Bustamante, Paco; Richard, P; Catry, T; Ramos, J; Le Corre, M.
Over 6-million pairs of sooty terns Sterna fuscata breed once a year in the southwest Indian Ocean, mostly on three islands of the
Mozambique Channel (Europa, Juan de Nova and Glorieuses) and in the Seychelles region. Seasonal reproduction in either winter
or summer is the dominant strategy in the area, but non-seasonal reproduction also occurred in some places like at Glorieuses
Archipelago. The feeding ecology of the sooty tern was investigated during the breeding seasons to determine whether terns
showed significant differences in their trophic ecology between locations. Regurgitations were analyzed to describe the diet of
individuals when breeding, and stable isotopes and mercury concentrations were used to temporally integrate over the
medium-term of...

Genetic improvement of common carp (Cyprinus carpio L.)
Provedor de dados: 5
Autores: Vandeputte, Marc.
Common carp was the first domesticated fish species and is now a major species in worldwide aquaculture. Although research has
generated a considerable body of knowledge about its genetics, genetic improvement programmes are virtually non-existent in this
species and only crossbreeding is used in practice. The main reasons are the inefficiency of methods usually effective in other
aquaculture species (monosexing, triploidy), and the bad image of selective breeding which is difficult to implement in ponds, and
for which reliable genetic parameters were missing until recently. These parameters are now becoming available through the use
of parentage assignment with microsatellite markers. However, the question of selective breeding for growth remains far from...

Strain-Dependent Norovirus Bioaccumulation in Oysters
Provedor de dados: 5
Autores: Maalouf, Haifa; Schaeffer, Julien; Parnaudeau, Sylvain; Le Pendu, Jacques; Atmar, Robert L.; Crawford, Sue E.; Le
Guyader, Soizick.
Noroviruses (NoVs) are the main agents of gastroenteritis in humans and the primary pathogens of shellfish-related outbreaks.
Some NoV strains bind to shellfish tissues by using carbohydrate structures similar to their human ligands, leading to the
hypothesis that such ligands may influence bioaccumulation. This study compares the bioaccumulation efficiencies and tissue
distributions in oysters (Crassostrea gigas) of three strains from the two principal human norovirus genogroups. Clear differences
between strains were observed. The GI.1 strain was the most efficiently concentrated strain. Bioaccumulation specifically
occurred in digestive tissues in a dose-dependent manner, and its efficiency paralleled ligand expression, which was highest
during the cold...

Diversity and composition of macrobenthic community associated with sandy shoals of the Louisiana
continental shelf
Provedor de dados: 5
Autores: Dubois, Stanislas; Gelpi, Carey; Condrey, Richard E.; Grippo, Mark A.; Fleeger, John W.
Along the Louisiana, USA continental shelf, sandy shoals are shallow, possibly oxygen-rich "islands" surrounded by deeper
muddy deposits prone to hypoxia. Shoals also contain significant quantities of fine sand that may be mined in the future for
coastal restoration. The ecological role of shoals remains poorly understood and we hypothesized that shoals provide critical
habitat for benthic invertebrates. Using Ship Shoal as a model system, we assessed the diversity and structure of macrobenthic
assemblages and how community structure varies with season and environmental parameters. High biomass (averaging 26.7 g
m(-2)) and high diversity (161 species) of macrobenthos was found in 2006. Polychaetes (45%-72 species) and crustaceans

In vitro research of anti-HSV-1 activity in different extracts from Pacific oysters Crassostrea gigas
Provedor de dados: 5
Autores: Olicard, Cecile; Didier, Yohann; Marty, Christel; Bourgougnon, Nathalie; Renault, Tristan.
Mortalities related to the detection of Ostreid Herpesvirus 1 (OsHV-1) have been previously reported in France among larvae and
spat of the Pacific oyster Crassostrea gigas. Adult oysters appear less sensitive to herpesvirus infections, although OsHV-1 has
been detected in adults without signs of disease or mortality. This suggests that the virus is able to persist in its host and that adult
oysters may be able to control OsHV-1 infection. Little is known about antiviral substances in invertebrates. The present work
concerns the research of antiviral substances in adult oyster C. gigas, where putative antiviral activities were monitored using 3
strategies: (1) in metabolites with variable polarity, (2) in peptidic extracts and (3) in crude haemolymph. In...

In situ growth potential of the subtidal part of green tide forming Ulva spp. stocks
Provedor de dados: 5
Autores: Merceron, Michel; Antoine, Virginie; Auby, Isabelle; Morand, P.
Ulva spp., the algae most responsible for green tides in Brittany (France), are found on the foreshore and in the most beachward
wave area (MBWA) of many bays during green tide phenomena. These algae have recently been seen drifting at greater depths
(reaching -20 m). In view of the significant quantities of algae found at these depths, and the less favorable conditions for algal
growth than in the intertidal zone, we attempted to determine if they could grow there. For that, during their maximum growth
period (from May to July), algae were picked up at three stations located on the foreshore, in the MBWA and in the subtidal
(deep) zones of the Bay of Douarnenez, and their nitrogen, carbon and chlorophyll a+b contents were determined, and their...

A method of geometric morphometrics was used to characterize body shape variation in meiotic gynogenetic and triploid sea bass
in comparison with diploid controls. A total of 13 coordinate landmark data were recorded on the profile of 34-month-old control
(n = 81), gynogenetic (n = 117) and triploid (n = 131) siblings generated from two females (A and B). Three main axes of
morphometric variation were consistent, and these accounted for 60.8 and 57.6% of the total variability in females A and B,
respectively. There were significant shape deviations of triploid and gynogenetic fish relative to the controls, and differences were
particularly evident in the progeny of one female. Overall, triploids displayed a more slender shape than diploids, whereas...

A preliminary genetic linkage map for the European flat oyster Ostrea edulis L.
Provedor de dados: 5
Autores: Lallias, Delphine; Lapegue, Sylvie; Harley, Crhis; Boudry, Pierre; Heurtebise, Serge; Beaumont, Andy.
The flat oyster Ostrea edulis is the species endemic to European coasts, both Atlantic and Mediterranean. It has been exploited
since Roman times, but its aquaculture production decreased from around 20000 tons in the 1950's to 1500 tons today because of
two successive diseases due to the intracellular parasites Marteilia refringens and Bonamia ostreae. Since 1985, Ifremer has been
undertaking a breeding program to produce families of oysters tolerant to Bonamia. In this context, a further step would be to
identify QTLs for resistance to this parasite. Therefore, as a first step a genetic map is now being built. The establishment of a
genetic linkage map will provide a foundation for the mapping of QTLs, with the ultimate objective to implement...

Provedor de dados: 5
Autores: Boudry, Pierre; Collet, Bertrand; Cornette, Florence; Hervouet, Veronique; Bonhomme, Francois.
Oysters, like many marine species have a very high fecundity. Previous studies have shown that populations, from both hatcheries
and the natural environment, have very low Ne/N ratios. These observations reveal high variation in reproductive success. In order
to study individual reproductive success under controlled conditions, we used microsatellite markers to quantify parental
contributions in in vitro crosses (5 males and 5 females) of Crassostrea gigas, the Pacific oyster. High polymorphism of the
microsatellites (more that 50 alleles per locus) eased the parentage identifications. The results of a cross allowing gametic
competition were compared with the results from a second cross where the gametes of the same parents were kept separate for

Diatoms are photosynthetic secondary endosymbionts found throughout marine and freshwater environments, and are believed to
be responsible for around one- fifth of the primary productivity on Earth(1,2). The genome sequence of the marine centric diatom
Thalassiosira pseudonana was recently reported, revealing a wealth of information about diatom biology(3-5). Here we report the
complete genome sequence of the pennate diatom Phaeodactylum tricornutum and compare it with that of T. pseudonana to
clarify evolutionary origins, functional significance and ubiquity of these features throughout diatoms. In spite of the fact that the
pennate and centric lineages have only been diverging for 90 million years, their genome structures are dramatically different and

Revealing pelagic habitat use: the tagging of Pacific pelagics program
Provedor de dados: 5
Autores: Block, Ba; Costa, Dp; Boehlert, Gw; Kochevar, Re.
Tagging of Pacific pelagics (TOPP) is a pilot program of the Census of marine life (CoML) that will lead to understanding of
pelagic habitat use by marine vertebrates and large squid in the North Pacific. Taking a multispecies approach, the TOPP project
will use a range of electronic tag technologies to put the distribution and behavior of pelagic organisms, in the context of the
oceanography of the North Pacific. Tag-bearing animals will be used as autonomous ocean profilers to enhance sparse
oceanographic observations for vast ocean regions. These autonomous ocean samplers will provide unprecedented coverage of the
water column structure of the North Pacific. The temporal and spatial data generated by this project will provide an
"organism-eye" view of...

Carbon conversion efficiency and population dynamics of a marine algae–bacteria consortium
growing on simplified synthetic digestate: First step in a bioprocess coupling algal production and
anaerobic digestion

Association of microalgae culture and anaerobic digestion seems a promising technology for sustainable algal biomass and biogas
production. The use of digestates for sustaining the growth of microalgae reduces the costs and the environmental impacts
associated with the substantial algal nutrient requirements. A natural marine algae–bacteria consortium was selected by growing
on a medium containing macro nutrients (ammonia, phosphate and acetate) specific of a digestate, and was submitted to a factorial
experimental design with different levels of temperature, light and pH. The microalgal consortium reached a maximum C
conversion efficiency (i.e. ratio between carbon content produced and carbon supplied through light photosynthetic C conversion
and acetate)...

Cyclogeostrophic balance in the Mozambique Channel
Provedor de dados: 5
Autores: Penven, Pierrick; Halo, Issufo; Pous, Stephane; Marie, Louis.
Three methods are proposed for the inclusion of inertia when deriving currents from sea surface height (SSH) in the Mozambique
Channel: gradient wind, perturbation expansion, and an iterative method. They are tested in a model and applied to satellite
altimetry. For an eddy of 25 cm amplitude and 100 km radius, typical of Mozambique Channel rings at 18°S, the error made with
geostrophy is 40% for the anticyclones and 20% for the cyclones. Inertia could reach one third of the pressure gradient.
Geostrophy underestimates subsurface currents by up to 50 cm s−1, resulting in errors of 30–40%. The iterative method results in
errors of <5% for the most part of the structure. The error RMS in velocities based on 8 years of model SSH is in excess of 30

Variations in the world's ocean heat storage and its associated volume changes are a key factor to gauge global warming and to
assess the earth's energy and sea level budget. Estimating global ocean heat content (GOHC) and global steric sea level (GSSL)
with temperature/salinity data from the Argo network reveals a positive change of 0.5 +/- 0.1 W m(-2) (applied to the surface area
of the ocean) and 0.5 +/- 0.1 mm year(-1) during the years 2005 to 2012, averaged between 60 degrees S and 60 degrees N and the

Comparison between three-dimensional linear and nonlinear tsunami generation models
Provedor de dados: 5
Autores: Kervella, Youen; Dutykh, Denys; Dias, Frédéric.
The modeling of tsunami generation is an essential phase in understanding tsunamis. For tsunamis generated by underwater
earthquakes, it involves the modeling of the sea bottom motion as well as the resulting motion of the water above. A comparison
between various models for three-dimensional water motion, ranging from linear theory to fully nonlinear theory, is performed. It
is found that for most events the linear theory is sufficient. However, in some cases, more-sophisticated theories are needed.
Moreover, it is shown that the passive approach in which the seafloor deformation is simply translated to the ocean surface is not
always equivalent to the active approach in which the bottom motion is taken into account, even if the deformation is supposed
to...

Status and future of molluscan pathology in North America

Autores: Elston, R.
Serious diseases have plagued the North American oyster industry for at least 75 years. These include Malpeque Bay disease,
M.S.X. disease, perkinsiosis, nocardiosis, oyster velar virus disease and others. Some of these diseases have proven intractable
since they are caused by infectious agents which have not yet been transmitted in the laboratory or which cannot yet be cultivated
outside of the host animal. The increased importance of aquaculture of these species and the advent of modern molecular
technologies in biology have provided both the impetus and the means to now advance the science of molluscan pathology.

Fatigue Behaviour of Glass Fibre Reinforced Composites for Ocean Energy Conversion Systems
Provedor de dados: 5
Autores: Boisseau, Amelie; Davies, Peter; Thiebaud, F.
The development of ocean energy conversion systems places more severe requirements on materials than similar land-based
structures such as wind turbines. Intervention and maintenance at sea are very costly, so for ocean energy supply to become
economically viable long term durability must be guaranteed. Cyclic loading is a common feature of most energy conversion
devices and composites are widely used, but few data are available concerning the fatigue behaviour in sea water of composite
materials. This paper presents the results from an experimental study to fill this gap. The fatigue behavior of composite materials
reinforced with different types of glass fibre is characterized in air and in sea water; the influence of testing in sea water rather

Restoration ecology of coastal lagoons: new methods for the prediction of ecological trajectories and
economic valuation
Provedor de dados: 5
Autores: De Wit, Rutger; Rey-valette, Helene; Balavoine, Juliette; Ouisse, Vincent; Lifran, Robert.
Conservation of the seven lagoons of the Palavas complex (southern France) has been severely impaired by nutrient
over-enrichment during at least four decades. The effluents of the Montpellier wastewater treatment plant (WWTP) represented
the main nutrient input. To improve the water quality of these lagoons, this WWTP was renovated and upgraded and, since the
end of 2005, its effluents have been discharged 11 km offshore into the Mediterranean (total investment €150 M).
Possibilities
of ecosystem restoration as part of a conservation programme were explored by a focus group of experts. Their tasks were: (i) to
evaluate the impact of the reduction of the nutrient input; (ii) if necessary, to design additional measures for an active restoration
programme;...

Bacteria associated with semi-continuous culture of Brachionus plicatilis , which is used as the first food of marine fish larvae,
were counted on Zobell 2216 E medium and identified. The numbers of bacteria were very high in both Brachionus (about 10
super(11) bact. per ml of digestive content) and in water (from 1.6.10 super(6) to 4.7.10 super(7) bact. per ml). The cultures were

The objective of this study, carried out in the Gironde estuary inlet, was to determine the nature of the seaward dispersion of
estuarine water and suspended sediments during a spring tide and high river flow. On June 3, 19(7, three flights were made over
the inlet, at mid ebb, low tide and mid flood. The planned flight at high tide was cancelled due to adverse meteorological
conditions. During each flight, thermal infrared coverage was obtained, together with black and white photographs. These data
were correlated with concomitant ground mesures of current velocity, salinity, temperature and suspended sediment concentration
Four types of water masses were identified during the tidal cycle: estuarine "very warm and turbid" water; estuarine "cooler and...

Population structure of Patella vulgata L. during succession on rocky shores in Southwest England
Provedor de dados: 5
Autores: Hawkins, S J; Southward, A J; Barrett, R L.
Large concrete blocks have been placed on the exposed south side of Plymouth Break-water in most years since 1954.
Examination of blocks of known age provides series of observations on community succession. Initial growth of green algae and
then Fucus is followed by large numbers of fast-growing newly-settled Patella vulgata . The Patella graze down the algae,
allowing subsequent build-up of a permanent population of barnacles. Inter-age class competition, together with the effects of the
barnacles, promote re-structuring of the Patella population. There are a series of fluctuations which subside in amplitude as the
community reaches maturity. The time-scale, however, is much longer (15-20 years) than anticipated from small experiments.

Autores: Le Brun, Eric.
After having defined the specificity of shellfish farming compared to agriculture and fishing, we used a global approach to study
shellfish farming in the Thau Lagoon. We present the Lagoon and the shellfish farming zones, then production and finally the
organization of this industry. Farms were then delimited, which required identifying concessions and which farming operation
they were part of. Insofar as the development of shellfish farms is contingent on the strategies adopted by the shellfish farmer, we
attempted to determine these strategies and observe the interactions between the development of the Lagoon and that of farms.

The aim of this study is to propose a 3-dimension reconstruction method of small-scale scenes improved by a new image
acquisition method for quantitative measurements. A stereovision system is used to acquire images in order to obtain several shots
of an object, at regular intervals according to a predefined trajectory. A complete methodology of 3D reconstruction is exposed to
perform a dense 3D model with texture mapping. A first result on natural images collected with the stereovision system during sea

Food source of intertidal nematodes in the Bay of Marennes-Oleron (France), as determined by dual
stable isotope analysis
Provedor de dados: 5
Autores: Riera, P; Richard, P; Gremare, A; Blanchard, G.
Nematodes living on an intertidal mudflat of the Marennes-Oleron Bay (France) were assayed for delta(13)C and delta(15)N
ratios together with their potential food resources between July 1992 and May 1993. Results suggest that nematodes do not exploit
all the components of the sedimented organic matter (SOM) pool at the same rate. Furthermore, based on coefficients of average
trophic enrichment found in the literature for both C and N, the enrichment of nematodes in C-13 and their depletion in N-15
relative to SOM suggest that microphytobenthos constitutes their main food source in this particular environment.

During the 1972 Midlante* cruise of the RV Jean Charcot to survey a limited area of the rift valley south of the Azores, a dredge
(CH-DR11) was taken at a depth of 1,360 fathoms in a depression near the foot of the eastern wall at latitude 36° 49.3' N and
longitude 33° 15' W. Two types of rocks were recognized from their structure and their degree of weathering. One type is
"slab-like" rock, 2 to 13 cm in diameter and 1 to 2 cm thick (Fig. la and b). The other type of rock consists of oval glassy pebbles
(1 to 5 cm in diameter, Fig. 1c) which were observed to jump and explode, one or two at a time, for 3 d after the dredge haul was

growth shows important seasonal fluctuations. It is minimal in February-March (3 to 4 µm.D-1) and maximal in June (6 to 8
µm.D-1). The growth of larvae from conditioned spawners does not differ from that of larvae from mature genitors collected in

Fractography deals with the microscopic study of the fracture surfaces of a structure in order to define the initiation and the
propagation of the damage and then the failure history of the structure (stress, environment ...). Today, we are able to identify the
causes of the failure of metallic parts based on pictures of typical fracture surfaces, but there is nothing similar for composite
materials. However, the increasing amount of literature devoted to fractography, as well as the constitution of "brain storming"
groups on a European level confirm scientific interest in this fracture analysis mode that permits a better understanding of the
existing relationship between the material's microscopic structure and its macroscopic mechanical behaviour. In...

Over the last decades, the fishing effort focused on crustaceans and especially on the lobster has continued to increase. This way,
the number of pots used by each boat has grown from a few dozen to several hundred. This process lead to an overexploitation of
the seabed and the catches do not go over 400 tonnes/years despite the increase of the means involved. Consequently, it has been
necessary to implement a number of new measures to protect the lobster stock, and some restricted areas have been created off the

Ecologie trophique de la tortue verte Chelonia mydas dans les herbiers marins et algueraies du
sud-ouest de l’océan Indien
Provedor de dados: 5
Autores: Ballorain, Katia.
Reproduction of sea turtles primarily relies on body reserves stored during the time spent on foraging grounds prior to the nesting
season. Accordingly, the investigation of foraging behaviour of sea turtles is critical for better assessing their biology but also for
conservation issues of these endangered species. Sea turtles contribute significantly to the consuming biomass of their ecosystem
and hence to its functioning, thus providing natural indications of the health of the ecosystem. Yet the trophic ecology of sea
turtles is poorly documented because their feeding grounds remain poorly known and for most of them hardly accessible. Among
sea turtles the green turtle is the only species where sub-adults and adults are mostly herbivorous feeding on...

Ecoviability for small-scale fisheries in the context of food security constraints
Provedor de dados: 5
Autores: Cisse, Abdoul; Doyen, L.; Blanchard, Fabian; Bene, Christophe; Pereau, J. -c.
This paper applies a stochastic viability approach to a tropical small-scale fishery, offering a theoretical and empirical example of
ecosystem-based fishery management approach that accounts for food security. The model integrates multi-species, multi-fleet
and uncertainty as well as profitability, food production, and demographic growth. It is calibrated over the period 2006–2010
using monthly catch and effort data from the French Guiana's coastal fishery, involving thirteen species and four fleets. Using
projections at the horizon 2040, different management strategies and scenarios are compared from a viability viewpoint, thus
accounting for biodiversity preservation, fleet profitability and food security. The analysis shows that under certain...

Depuis 1991 , des mortalités massives sporadiques sont rapportées, en France, de manière régulière chez des larves et des
juvéniles de différentes espèces de mollusques bivalves marins. Certains de ces épisodes de mortalité ont pu être associés à la
détection de virus. Ces derniers par leur morphologie, leur cycle de réplication et leur localisation ont été apparentés à la famille
des Herpesviridae.
Cependant, les outils de diagnostic disponibles jusqu'alors (histologie et microscopie électronique à
transmission) n'étaient pas adaptés à l'étude de ces virus du fait de leur manque de spécificité et de la lourdeur de leur mise en
oeuvre. Par ailleurs, se posait la question de l'implication des virus détectés dans les phénomènes de mortalité observés. En...

Autores: Carlsoon, Per; Edling, Hélène; Bechemin, Christian.
Dissolved organic matter in the form of riverine humic substances stimulated the growth of both axenic nitrogen-limited
Alexandrium catenella cultures and nitrogen-limited cultures with a marine bacterial community present. The biomass increase of
A. catenella could not be accounted for by utilization of inorganic nitrogen compounds. However, there was a considerable release
of dissolved free and combined amino acids from the humic substances that was utilized by A. catenella. About 40% of the
nitrogen used by A. catenella in the axenic treatment with humic substances added was taken up as organic nitrogen. Bacterial
aminopeptidase and beta -glucosidase activity was stimulated by the addition of humic substances and bacterial growth increased
several-fold....

Baie de Vilaine : juillet 1982 mortalité massive de poissons l'analyse des causes et des mécanismes du

Provedor de dados: 5
Autores: Merceron, Michel.
At the end of July 1982, a massive number of fish and benthic invertebrates died in Vilaine Bay. The mass of fish concerned has
been estimated at several tens of tonnes. The analysis of the event's conditions indicates that it was asphyxiation caused by a very
pronounced depletion of dissolved oxygen in the bay's bottom waters. The appearance of toxic phytoplankton in the years that
followed (Dinophysis) is aseparate topic of research by IFREMER.
The most likely mechanism of that anoxia is a succession of
events: (1) a first flood of Vilaine River inducing a vertical stratification of waters in Vilaine Bay, (2) an intense and superficial
bloom of marine phytoplankton, (3) a stormy weather breaking up the stratification and mixing superficial...

Dynamics of an Equatorial River Plume: Theory and Numerical Experiments Applied to the Congo

Autores: Vic, Clement; Berger, Henrick; Treguier, Anne-marie; Couvelard, Xavier.
The Congo River has the second largest rate of flow in the world and is mainly responsible for the broad tongue of low-salinity
water that is observed in the Gulf of Guinea. Despite their importance, near-equatorial river plumes have not been studied as
thoroughly as midlatitude plumes and their dynamics remain unclear. Using both theory and idealized numerical experiments that
reproduce the major characteristics of the region, the authors have investigated the dynamics of the Congo River plume and
examine its sensitivity to different forcing mechanisms. It is found that near-equatorial plumes are more likely to be surface
trapped than midlatitude plumes, and the importance of the effect in describing the strong offshore extent of the low-salinity

Since the beginning of the century, no serious attempt at salmon fishing had been undertaken in Saint-Pierre et Miquelon. Faced
by a great lack of information and experience, it is understandable that this activity never attracted the archipelago's fishermen.
Reaching its goals, we hope that the campaign launched by the ISTPM in 1975 answered this need. The presence of salmon in the
archipelago's waters has been demonstrated as well as the possibility of exploiting this natural resource through common means
usable by local artisanal fishermen. During our latest campaign, we found at least three good fishing sites and hope that new sites
will be discovered in the future. We therefore think that a seasonal fishing activity, though limited, could be carried...

Over the past decade Surface Plasmon Resonance (SPR) techniques have been applied to the measurement of numerous analytes.
In this article, an SPR biosensor system deployed from an oceanographic vessel was used to measure dissolved domoic acid (DA),
a common and harmful phycotoxin produced by certain microalgae species belonging to the genus Pseudo-nitzschia. During the
biosensor deployment, concentrations of Pseudo-nitzschia cells were very low over the study area and measured DA
concentrations were below detection. However, the in situ operational detection limit of the system was established using

Investment and factor remuneration in small-scale fisheries
Provedor de dados: 5
Autores: Lantz, Frederic; Junqueira-lopez, R.
Investment behaviour is a complex process which plays a major role in fisheries dynamics because it determines the size of the
fishing fleet. The purpose of this paper is to examine the consequences of the main characteristics of fishing activity on
investment. The theoretical dynamic model of a fishery shows us the "bangbang" pallern of investment. Furthermore, fishing
activity has a high intrinsic variability. Thus, the system in which income is shared between the crew and the ship owner is also
considered as a way of sharing risks and so reducing the variability ofinvestment return. Finally, the type of investment financing
(subsidies, loans) can strongly stimulate fisheries dynamics but can also have some undesirable effects. [NOT CONTROLLED

A method for optimal analysis of fields with spatially-variable mean
Provedor de dados: 5
Autores: Le Traon, Pierre-yves.
This brief report addresses the problem of objective analysis of fields with spatially variable mean. Conventional objective
analysis is confined to fluctuations, where the larger scale is assumed to be known; this report shows how to use the method
described by Davis (1985) to estimate simultaneously a large-scale component and a mesoscale component with an accurate error
budget. The extension to multivariate analysis is also discussed. The method is then applied to simulated data; this illustrates its
contribution in relation to conventional objective analysis.

Devenir des bactéries entériques en milieu littoral. Effet du stress sur leur survie
Provedor de dados: 5
Autores: Pommepuy, Monique.
Le devenir des bactéries entériques rejetées en mer a été étudié sur cinq zones côtières du littoral français : la côte Ouest du
Cotentin, la rade de Brest, l'estuaire de Morlaix, la rade de Toulon et la Baie de Fort de France. Sur chaque site, une étude a
permis de déterminer les concentrations en coli formes thermotolérants et en streptocoques fécaux dans les principaux apports.
Les salmonelles ont également été recherchées sur trois de ces secteurs. Un calcul de flux permet d'apprécier l'importance des
rejets urbains. Dans ces eaux généralement très chargées en contamination fécale, la présence de salmonelles a presque toujours
été détectée. La qualité des eaux littorales et des sédiments côtiers a ensuite fait l'objet d'observations. Les...

Hepatic phosphoenolpyruvate carboxykinase gene expression is not repressed by dietary
carbohydrates in rainbow trout (Oncorhynchus mykiss)
Provedor de dados: 5
Autores: Panserat, Stéphane; Plagnes Juan, E; Breque, Jeanine; Kaushik, Sadasivam.
Phosphoenolpyruvate carboxykinase (PEPCK) is a rate-limiting enzyme in hepatic gluconeogenesis and therefore plays a central
role in glucose homeostasis. The aim of this study was to analyse the nutritional regulation of PEPCK gene expression in rainbow
trout (Oncorhynchus mykiss), which are known to use dietary carbohydrates poorly. A full-length hepatic PEPCK cDNA (2637
base pairs with one open reading frame putatively encoding a 635-residue protein) was cloned and found to be highly homologous
to mammalian PEPCKs. The presence of a putative peptide signal specific to a mitochondrial-type PEPCK in the deduced amino
acid sequence suggests that this PEPCK gene codes for a mitochondrial form, In gluconeogenic tissues such as liver, kidney and
intestine,...

Global average of air-sea CO2 transfer velocity from QuikSCAT scatterometer wind speeds
Provedor de dados: 5
Autores: Boutin, J.; Quilfen, Yves; Merlivat, L.; Piolle, Jean-francois.
The absolute calibration of the relationship between air-sea CO2 transfer velocity, k, and wind speed, U, has been a topic of
debate for some time, because k global average, < k >, as deduced from Geochemical Ocean Sections Study oceanic C-14
inventory has differed from that deduced from experimental k-U relationships. Recently, new oceanic C-14 inventories and
inversions have lead to a lower < k >. In addition, new measurements performed at sea in high-wind speed conditions have
led to new k-U relationship. Meanwhile, quality and sampling of satellite wind speeds has greatly improved. The QuikSCAT
scatterometer has provided high-quality wind speeds for more than 7 years. This allows us to estimate the global distributions of k

Maintenance of discrete bacterial populations in adjacent marine habitats.

Autores: Robb, F; Muir, D; Davis, C.
Some mechanisms of selection which operate on marine Vibrio and Pseudomonas strains during survival in dilute environments
have been examined. Mannitol uptake and utilisation systems are more efficient in the Vibrio strain compared with the
Pseudomonas strain during starvation survival. A Vibrio mutant strain lacking mannitol uptake showed no greater loss of viability
during starvation survival than mannitol positive strains. The Vibrio strain appears to be constitutive with respect to mannitol
uptake systems, whereas the Pseudomonas strain examined is inducible. Active uptake systems for glucose, glutamate, alanine and
aspartic acid were efficiently maintained during starvation survival in the Vibrio strain. Results suggest that membrane uptake

Coastal hydrodynamics in a windy lagoon

The nonlinear hydrodynamics (3D RANS model) in a wide semi-enclosed windy lagoonal ecosystem is accurately investigated in
the context of analyzing the limiting conditions of the recovery of submerged aquatic vegetation (SAV). Among the main natural
hydrodynamical forcings, we consider the wind effect. We mainly focus attention to characteristic velocities (free surface and
bottom) and to free surface elevation in the nearshore regions (with shallow water) where SAV were severely damaged in the past
decades. Our main result relates to wind effects that form downwind coastal jets, alongshore, in shallow water areas, due to Berre
bathymetry. Such coastal jets, which were never described previously in Berre lagoon literature, give rise to substantial bottom...

Some considerations on neutral surface-analysis

The development of the concept of a "neutral surface" - an isopycnal surface refined by the introduction of a variable reference
pressure - is presented. Problems in approximating such a surface (concerning, for example and inter alia, the reference water
parcel to be used in starting a neutral surface; or the reference pressure and parcel to be used and path to be followed in extending
a neutral surface from station to station) are examined. These problems arise because oceanographic reality only provides data at
discrete depths from given station networks. The effects of compressibility dependence on the thermohaline properties of a water
parcel in delineating a neutral surface are also considered. A new method of approximating neutral surfaces is...

Multiple correspondance analysis and hierarchical ascending classification were used to study catch rate variations in the French
deep-sea trawler fleet between 1972 and 1989. The use of these methods clarifies the sometimes complex relationships between
catch rates of the main species landed within the total catch and allows a classification of the typical catch rate structures over this
period. Factors such as year and fishing areas are those which best explain the observed variations; seasonal variations play a
minor role. Catch rates increased and more species were caught between 1972 and 1989. The study shows the relationship
between these developments and changes in fishing effort allocation strategies and in fleet structure. Trawlers which exploited...

Vibrio tapetis is the marine bacterium responsible for the brown ring disease (BRD) affecting die manila clam, Ruditapes

dot blot hybridisation and species-specific primed PCR (SSP-PCR). The probe and primers have been tested on 60 strains,
including referenced Vibrio sp., Gram negative and positive bacteria, marine bacteria samples and isolated clam bacteria. For all

reactions involved in RNA primer elimination in vitro. In my dual-labelled system, polymerase D performed efficient strand
displacement DNA synthesis, generating 5'-RNA flaps which were subsequently released by Fen1, before ligation by Lig1. In this
pathway, the initial cleavage event by RNase HII facilitated RNA primer removal of Okazaki fragments. In addition, I have shown
that polymerase B was able to displace downstream DNA strands with a single ribonucleotide at the 5'-end, a product resulting
from a single cut in the RNA initiator by RNase HII. After RNA elimination, the combined activities of strand displacement DNA

during large daily cycles. First, Ttop is compared to the temperature measured at 17 -cm depth from a float tethered to the SVP
drifter. These 2007-12 SVP drifters present a larger daily cycle by 1%-3% for 1 degrees-2 degrees C daily cycle amplitudes, with
a maximum difference close to the local noon. The difference could result from flow around the SVP drifter in the presence of
temperature stratification in the top 20 cm of the water column but also from a small influence of internal drifter temperature on...

Transverse properties of carbon fibres by nano-indentation and micro-mechanics
Provedor de dados: 5
Autores: Maurin, R; Davies, Peter; Baral, N; Baley, C.
In this study the transverse modulus of three high modulus (M40, M46 and K63712) carbon fibres has first been measured directly
by nano-indentation measurements. Transverse tensile tests on unidirectional epoxy composites were then performed, and the
comparison was made between transverse fibre properties from indentation and those needed to obtain the measured transverse
composite modulus using micromechanics expressions. The latter tended to underestimate values from indentation, by up to 36%,
and reasons for this are discussed. Values of transverse fibre modulus determined by both methods decrease as longitudinal fibre
modulus increases.

Present-day evolution of sand waves on a sandy shelf bank
Provedor de dados: 5
Autores: Lankneus, J; Moor, Gde.
A sand wave field on the northern extremity of the Kwintebank (Belgian continental platform) was mapped three times over a
period of one year with the help of side-scan sonar and echosounder. The geometric characteristics of the sand waves are
described in detail. Shifting of the sand waves occurred in the directions of both their gentle and steep slopes. The net movement
over one year is, however, minimal.

Problems and perspectives of the pearl oyster aquaculture in French Polynesia.
Provedor de dados: 5
Autores: Cabral, P.
The first attempt to obtain artificial pearls from the black-lip pearl oyster Pinctada margaritifera in French Polynesia dates back to
1963. The pearl oyster culture has grown quickly especially since the eighties. This industry is now the first exportation in value
of French Polynesia. 19 atolls of the Tuamotus island have at this time one or more farms and this activity has more and more
attractiveness. The rise of this industry has consequently a lot of socio-ecomic repercussions on these atolls. However, as a young
industry, the technics and the development are not always controlled and a lot of problems appeared these last years.

Analysis and Interpretation of Frequency–Wavenumber Spectra of Young Wind Waves
Provedor de dados: 5
Autores: Leckler, Fabien; Ardhuin, Fabrice; Peureux, Charles; Benetazzo, Alvise; Bergamasco, Filippo; Dulov, Vladimir.
The energy level and its directional distribution are key observations for understanding the energy balance in the wind-wave
spectrum between wind-wave generation, nonlinear interactions, and dissipation. Here, properties of gravity waves are
investigated from a fixed platform in the Black Sea, equipped with a stereo video system that resolves waves with frequency f up
to 1.4 Hz and wavelengths from 0.6 to 11 m. One representative record is analyzed, corresponding to young wind waves with a
peak frequency fp = 0.33 Hz and a wind speed of 13 m s−1. These measurements allow for a separation of the linear waves from
the bound second-order harmonics. These harmonics are negligible for frequencies f up to 3 times fp but account for most of the
energy at higher...

Autores: Chardy, Pierre.
Systematic of the Haploniscidae family is cleared by two approaches : phenetic relationships between species through a multiple
criteria analysis and phylogenetic attempt based on a few number of characters of which the evolutive meaning is discussed.
Choice and coding of characters, taxonomic distance and mathematical methods are commented. Phenetic classification is
expressed by two complementary techniques : ordination (Analysis of Correspondences, CORDIER, 1966) and hierarchy (cluster
analysis of Roux, 1968). The resulting scheme provides a picture of the morphological affinities between the 5 genus and the 73
species of this family ; divisions inside genus Haploniscus are defined. A phylogenetic hypothesis, deduced by the minimum steps

The use of the Rotifer Brachionus plicatilis has spread for a few years in the laboratories dealing with the rearing of marine fish
larvae. Thanks to the works by Theilacker and Mac Master (1971) in the U.S.A., and by Hirayama and Ogawa (1972) and
Hirayama and Kusano (1972) in Japan, the conditions to follow to rear large quantities are well-known. The common method used
consists of placing a Rotifer inoculum in a mono or plurispecific culture of planktonic algae ("green water"), in leaving them to
multiply exponentially at the expense of the alga, and to use them before they run out of food. [...]

Co-Occurrence and Habitat Use of Fin Whales, Striped Dolphins and Atlantic Bluefin Tuna in the
Northwestern Mediterranean Sea
Provedor de dados: 5
Autores: Bauer, Robert; Fromentin, Jean-marc; Demarcq, Herve; Brisset, Blandine; Bonhommeau, Sylvain.
Different dolphin and tuna species have frequently been reported to aggregate in areas of high frontal activity, sometimes
developing close multi-species associations to increase feeding success. Aerial surveys are a common tool to monitor the density
and abundance of marine mammals, and have recently become a focus in the search for methods to provide fisheries-independent
abundance indicators for tuna stock assessment. In this study, we present first density estimates corrected for availability bias of
fin whales (Balaenoptera physalus) and striped dolphins (Stenella coeruleoalba) from the Golf of Lions (GoL), compared with
uncorrected estimates of Atlantic bluefin tuna (ABFT; Thunnus thynnus) densities from 8 years of line transect aerial surveys.

Autores: Brischoux, Francois; Rolland, Virginie; Bonnet, Xavier; Caillaud, Matthieu; Shine, Richard.
Since the transition from terrestrial to marine environments poses strong osmoregulatory and energetic challenges, temporal and
spatial fluctuations in oceanic salinity might influence salt and water balance (and hence, body condition) in marine tetrapods. We
assessed the effects of salinity on three species of sea snakes studied by mark-recapture in coral-reef habitats in the
Neo-Caledonian Lagoon. These three species include one fully aquatic hydrophiine (Emydocephalus annulatus), one primarily
aquatic laticaudine (Laticauda laticaudata), and one frequently terrestrial laticaudine (Laticauda saintgironsi). We explored how
oceanic salinity affected the snakes' body condition across various temporal and spatial scales relevant to each species' ecology,...

Evolution of marine oil pollution made the study of microbial degradation a current matter of importance. The present work dealt
with preliminary assays in vitro of a sys-tematic study of petroleum degrading Bacillus species. Degradation of petrol during the
different experimentations was followed with infra-red analyses. Progressive elimination of alcanes and isoalcanes was controlled
by gas- chromatography. Out of the 37 strains of Bacillus subtilis, B_. polymyxa, B. megaterium and Sporosar- cina tested, 10
could grow with petrol as unique source of carbon. The factors of growth as supplemented in these experiments hardly accelerated

Despite the economic importance of numerous oyster species throughout the world, our knowledge of their systematics and
phylogeography remains fragmentary. In Europe, the indigenous species, Ostrea edulis, suffered overexploitation as well as two
successive parasitosis over the last century. However, this species is still cultivated in Europe, and especially in Spain and France.
Its distribution area stretches from the Atlantic coasts of Europe to the north of Africa as well as around the Mediterranean and
Black Sea. Its Mediterranean and South Atlantic distribution area is shared with another indigenous species, the dwarf oyster,
Ostreola stentina. Its very small adult size (a few centimetres) makes its culture pointless from a commercial point of view....

Pollution of nature by plastics is a major environmental problem and the challenge for the future is to manage the lifetime of
polymers better. The aim of this study is to establish a baseline on degradation mechanism and degradation kinetics for lifetime
prediction of polylactide (PLA) in a marine environment. The ageing of PLA was accelerated by raising temperature in distilled
water, filtered and renewed seawater and natural seawater. Samples were immersed in distilled water for six months at different
temperatures (25, 30, 40 and 50°C) in order to evaluate the influence of temperature on PLA degradation kinetics and to predict
lifetime. Then, samples were immersed in seawater both in the laboratory and at sea, in order to compare the effects of...

Autores: Faucher, Karine; Fichet, Denis; Miramand, Pierre; Lagardere, Jean-paul.
Behavioural responses of sea bass Dicentrarchus labrax were investigated after exposure to cadmium ions in laboratory-controlled

system neuromasts, and to determine the behavioural consequences of such a sensory blockage. For this, fish escape behaviour in
response to an artificial water jet was recorded using a 25-frames s(-1) analog video camera before and after cadmium exposure.
Experimental set up was tested with fish whose lateral line system was artificially inactivated by antibiotics (gentamicin and

The development of robust classification model is among the important issues in computer vision. This paper deals with weakly
supervised learning that generalizes the supervised and semi-supervised learning. In weakly supervised learning training data are
given as the priors of each class for each sample. We first propose a weakly supervised strategy for learning soft decision trees.
Besides, the introduction of elms priors for training samples instead of hard class labels makes natural the formulation of an
iterative learning procedure. We report experiments for UCI object recognition datasets. These experiments show that recognition
performance close to the supervised learning can be expected using the propose framework. Besides, an application to...

Self-sampling of cod in the Celtic Sea
Provedor de dados: 5

Since 2003, the application of restrictive TAC for cod in area VIIb-k has led some French Professional Organisations to manage
their restrictive quota by imitations of landings by trip or period or by prohibiting the landings of the smallest commercial
category. In consequence of that, le level of discarding has increased by high grading practice. In the lack of available and reliable
data to estimate the level of discarding and the amount of discarded fish, the assessment of Celtic Sea Cod in Divisions VIIe-k has
been in recent years more and more uncertain, especially in estimating younger year classes, for a fishery which can be qualified
as a recruitment fishery. On a Professional Organisation (PMA= Pêcheries Manche-Atlantique) initiative and in the...

Dans un même secteur d'élevage de la baie de l'Aiguillon, vraisemblablement à cause de certaines inégalités de nutrition, un
déséquilibre du développement des mollusques a été constaté depuis plusieurs années. Soucieux d'apporter une solution à ce
problème de première importance pour la région, et conscient de ce que cette solution doit passer par une recherche de
l'amélioration de la circulation des eaux dans la zone des bouchots, IFREMER (Institut Français de la mer) a confié au Laboratoire
Central d'Hydraulique de France (LCHF) une étude courantologique dans la baie de l'Aiguillon. Cette étude comporte les trois
phases suivantes : * une campagne de mesures devant permettre de préciser les caractéristiques de la courantologie dans la zone

Veille écologique : vulnérabilité morpho-sédimentaire du littoral aux pollutions par hydrocarbures de
la Pointe Saint Mathieu au Sillon du Talbert
Provedor de dados: 5
Autores: Berne, Serge.
La notion d'indice de vulnérabilité aux hydrocarbures a été introduite par HAYES (1976). Elle permet d'estimer la "durée de
présence" des hydrocarbures dans un milieu donné (l'environnement étant d'autant plus sensible que cette durée augmente) ; des
observations réalisées à la suite de nombreuses marées noires ("METULA" ,"URQUIOLA" , "JACOB MAERSK", ARROW",
"AMOCO CADIZ", "TANIO" ••• ) permettent de conclure que ce sont la nature des sédiments et le niveau d'énergie auquel ils
sont soumis qui déterminent cette vulnérabilité. Dans un premier temps, on a tenté de préciser l'influence de différents paramètres
sur le comportement des hydrocarbures dans les sédiments, puis, à la lumière de cette classification, d'établir une carte au 1/25

A novel strictly anaerobic thermophilic heterotrophic bacterium, strain SLHLJ1T, was isolated from a Pacific hydrothermal
sediment. Cells were Gram-negative coccobacilli (approximately 1.0 × 0.6 μm) with a toga. It grew at temperatures between 33
and 78 °C (optimum 70 °C). Elemental sulphur and l-cystine stimulated its growth. It contained C16:0, C16:1 ω11c, C18:0 and
C18:1 ω9c as major fatty acids (>5 %), 3 phospholipids and 2 glycolipids as polar lipids. Its DNA G+C content was 43.7
mol%. Phylogenetic analyses based on 16S rRNA gene sequences placed strain SLHLJ1T within the family Thermotogaceae. The
novel isolate was most closely related to Kosmotoga arenicorallina (97.93 % 16S rRNA gene sequence similarity), K. olearia

Quelques chiffres nous permettront de situer la part de la pêche à la langouste verte dans l'activité générale du port.
En 1955 :
381 tonnes de langoustes vertes ont été débarquées à Douarnenez, représentant une valeur de 265 millions de francs ; soit plus de
2% en poids et plus de 16% en valeur des produits de la mer commercialisés dans ce port. Si l'on s'en tient uniquement à la

The microbiological quality of coastal waters and shellfish harvesting areas in Brittany (France) can be affected by faecal
pollutions from human activities and animal breeding (especially pigs and cattle). To discriminate among faecal pollution of
human and animal origin, a library-independent microbial source tracking method was selected: Bacteroidales host-specific 16S
rRNA gene markers by real-time Polymerase Chain Reaction (PCR). A human-specific Bacteroidales marker (Hum-1-Bac) was
designed. Tested on faecal samples, the Hum-1-Bac marker showed 95 % sensitivity and 95 % specificity (n= 80). Average values
(± STD) of the Hum-1-Bac marker were found to be 7.3 ± 1.4 16S rRNA gene copies per g wet faeces in human faeces samples

Background Senegalese sole (Solea senegalensis) and common sole (S. solea) are two economically and evolutionary important
flatfish species both in fisheries and aquaculture. Although some genomic resources and tools were recently described in these
species, further sequencing efforts are required to establish a complete transcriptome, and to identify new molecular markers.
Moreover, the comparative analysis of transcriptomes will be useful to understand flatfish evolution. Results A comprehensive
characterization of the transcriptome for each species was carried out using a large set of Illumina data (more than 1,800 millions
reads for each sole species) and 454 reads (more than 5 millions reads only in S. senegalensis), providing coverages ranging

Microalgal populations along French coasts (English Channel, Bay of Biscay and Mediterranean Sea) have been sampled twice a
month since 1987 within the context of the French Phytoplankton and Phycotoxin Monitoring Network (REPHY). This study used
these data to characterize the large-scale geographical structures of microphytoplankton communities and to determine whether
'homogeneous' geographical areas exist in which microalgal populations display similar temporal variability schemes. Once the
temporal variability component shared by all sampled coastal sites was identified, the 'residual' site-specific component was
analyzed. Multivariate ordination methods were used to determine seasonal and inter-annual variability. The expected-temporal

Fortnightly tidal asymmetry inversions and perspectives on sediment dynamics in a macrotidal

Provedor de dados: 5
Autores: Toublanc, Florence; Brenon, Isabelle; Coulombier, T.; Le Moine, Olivier.
Tidal asymmetry is a phenomenon that characterises estuarine hydrodynamics and has a strong impact on sediment dynamics.
Extensive research has been dedicated to studying tidal dynamics in semidiurnal macrotidal estuaries, highlighting several general
principles. The ratio of flood to ebb peak velocities and differences in ebb and flood durations are often used to characterise the
asymmetry encountered in estuaries. In the Charente estuary (French Atlantic coast), water surface elevation data obtained using
an ADCP (Acoustic Doppler Current Profiler) and a tide gauge show that the duration asymmetry undergoes inversions during the
spring-neap tidal cycle. A two-dimensional hydrodynamics model is used to investigate the connection between spring-neap...

Species diversity is widely recognized as an important trait of ecosystems’ functioning and resilience. Understanding the causes of
diversity patterns and their interaction with the environmental conditions is essential in order to effectively assess and preserve
existing diversity. While diversity patterns of most recurrent groups such as fish are commonly studied, other important taxa such
as cephalopods have received less attention. In this work we present spatio-temporal trends of cephalopod diversity across the

Epi-bathyal ostracod assemblage in Holocene Rhone deltaic sediments (Gulf of Lions, NW
Mediterranean) and their palaeoecological implications
Provedor de dados: 5
Autores: Fanget, Anne-sophie; Bassetti, Maria Angela; Berne, Serge; Arnaud, Mireille.
Since the Last Glacial Maximum, the Rhone River, which is the most important source of freshwater and sediment to the western
Mediterranean Sea, migrated in a north-westward direction during the rapid Deglacial and Early Holocene sea-level rise. During
the phase of global high sea-level (Middle and Late Holocene), an overall eastward migration of the Rhone outlet, under natural
and/or human influence, is recorded through several sediment accumulations confined along the inner shelf in the form of deltaic
lobes. These lobes that make up the whole Rhone subaqueous delta represent very expanded sedimentary archives of the Rhone
Holocene history. In this paper, using three long piston cores retrieved from the most recent Bras de Fer (RHS-KS55) and

We have studied the exopolysaccharide produced by Cobetia marina DSMZ 4741, a marine bacterium isolated from coastal
seawater. This strain is able to produce a polysaccharide in presence of carbon sources as glucose, mannitol and alginate. The
maximum production occurs in aerobic condition, during the end of the exponential phase. The polymer is a non-viscous, acidic
heteropolysaccharide of 270 kDa constituted of a repeating unit of: →2)-β-D-Ribf-(1→4)-[7,8-O-(Pyr)]-α-D-KDOp-(2→ This
kind of chemical structure is generally related to K-antigen polysaccharide of pathogenic Escherichia coli strains. This is the first

Time-series analysis is one of keys opening towards the future for marine sciences and industry to understand ocean processes and
their dynamics. It not only helps identifying the phenomenon represented by sequences of observations, but also helps forecasting
events by feeding models. Thanks to technological progress, marine scientists are benefiting from longer and longer data
timeseries with higher acquisition frequency, but they are also challenged by the need to optimize the analysis of these time-series
in the face of the increasing amount of data. These considerations raised the idea that sharing time-series analysis methods across
marine science topics would help scientists and engineers to improve their knowledge of existing methods, optimize the...

The Costa target areas exhibit the variability of slope instabilities needed to improve our understanding of sediment physical and
mechanical properties in areas prone to sliding. That is why in this project, we have analysed the different slope failures events
from different parts of the Costa target areas, which reflect diverse triggering mechanisms. The aim of the first part of this study
was to identify the geotechnical response of the sediment to different external mechanisms (earthquake, rapid sedimentation and
gas hydrate melting). We have focused on the relation between external mechanisms and the consequence change in the in-situ
stress state and the physical, mechanical, and elastic properties of the sediment. In the second part of the paper, the...

Effets de la pêche et du réchauffement climatique sur la coexistence spatiale des espèces de poissons
du golfe de Gascogne. Conséquences pour les pêcheries
Provedor de dados: 5
Autores: Blanchard, Fabian; Thebaud, Olivier; Guyader, Olivier; Lorance, Pascal; Boucher, Jean; Chevaillier, Pierre.
The populations of fishes dwelling near the sea bed (demersal species) on the continental shelf are usually the object of intense
commercial exploitation. The Bay of Biscay shelf is no exception. Hence, populations suffer from this exploitation. Moreover, the
general role played by hydro-climatic variations in the regulation of the abundance of demersal fish populations (population
dynamics) is traditionally admitted. In the Bay of Biscay, a warming of the surface water has been observed over the three last
decades (Koutsikopoulos et al., 1998). Climate change therefore has potential consequences on fish communities. Thus, the
structure and dynamics of fish populations on the continental shelf of the Bay of Biscay are susceptible to suffer both from the...

A spatially explicit ecosystem model of seston depletion in dense mussel culture
Provedor de dados: 5
Autores: Grant, J; Bacher, Cedric; Cranford, P; Guyondet, T; Carreau, M.
A fully-coupled biological-physical-chemical model of a coastal ecosystem was constructed to examine the impact of suspended
mussel culture on phytoplankton biomass in Tracadie Bay, Prince Edward Island, Canada. Due to the extent of mussel culture
there, we hypothesised that shellfish filtration would control the concentration and distribution of phytoplankton and other
suspended particles in the bay. Circulation was delineated with a tidally-driven 2D numerical model and used to drive an
ecosystem model with a focus on pelagic components including phytoplankton production, nutrients, detritus, and mussels. The
benthos were treated as a sink. Nutrients and seston were forced by tidal exchange and river input, with phytoplankton
additionally forced by...

Assessments of anthropogenic CO2 distribution in the tropical Atlantic Ocean
Provedor de dados: 5
Autores: Touratier, Franck; Goyet, C; Coatanoan, Christine; Andrie, C.
With a limited number of properties (salinity, temperature, total dissolved inorganic carbon, total alkalinity, and oxygen) from a
recent cruise in the tropical Atlantic Ocean, We use the simple and recent approach TrOCA (Tracer combining Oxygen, inorganic
Carbon, and total Alkalinity) to estimate the distribution of anthropogenic CO2 along three latitudinal sections. In order to assess
the quality of the anthropogenic CO2 distribution, results from the method are compared to the CFC-11 measurements. We
discuss the large-scale distribution of the main water masses of the tropical Atlantic Ocean in the light of the anthropogenic CO2
and the CFC-11 distributions. Keeping in mind that the anthropogenic CO2 emission began similar to 60 years earlier than that...

Periodicity of Remnant Arcs and Back-Arc Basins of the South Philippine Sea
Provedor de dados: 5
Autores: Scott, Robert; Kroenke, L.
The progressive evolution of the South Philippine Sea island arc-back-arc complex deduced from drilling on Glomar Challenger
Leg 59 places significant restraints upon tectonic processes that may operate in convergent plate boundaries characterized by
back-arc spreading systems. As previosuly recognized, remnant arc precursors of the modern Mariana arc and intervening
back-arc basins progressively developed from west to east to form the Palau-Kyushu Ridge, the Parece Vela Basin, the West
Mariana Ridge, and finally the modern Mariana Trough and Mariana arc. New data suggest that initial periods of back-arc
spreading are coincident with minimal arc volcanism rather than major periods of arc volcanism as previously suspected.

Comparison of the properties of scutched flax and flax tow for composite material reinforcement
Provedor de dados: 5
Autores: Martin, Nicolas; Davies, Peter; Baley, Christophe.
The industrial production of flax fibers yields two fibrous products: scutched fibers are valuable for their length, fineness and
cleanness, while tows are entangled, impure and are low-priced. There is a need for technical data to compare these two kinds of
fibers beyond the difference of appearance, and to assess their potential as composite material reinforcements. In this work, we
have compared the properties of scutched flax and flax tows from the same batch. The morphology was first assessed by
measuring the length, cleanness and fineness of fiber bundles. The tensile properties of single fibers and of unidirectionally
reinforced epoxy composites were then measured. The results show that the morphology of flax tows is different from but close to

Autores: Roos, David; Roux, Olivier; Conand, François.
The main characteristics of the biology of bigeye scad were studied from commercial fishery catches around Reunion Island.
Biometric relationships were calculated. The monitoring of size distribution, aggregated by month, allowed us to estimate the
theoretical growth equation using the ELEFAN software. The von Bertalanffy growth parameters were adjusted with a seasonal
modulation: L8 = 265 mm; K = 1.64 year-1; c = 0.068; ? = 0.38. The growth of the cohort was quite high during the austral
summer (November-April) and decreased during the austral winter (May-October). The arrival of a new cohort with homogeneous
small sizes (65 to 90 mm) in the fishery in November coincided with the disappearance of large individuals. A feature of the

Androgenesis is a form of uniparental reproduction leading to progenies inheriting only the paternal set of chromosomes. It has
been achieved with variable success in a number of freshwater species and can be attained by artificial fertilization of genetically
inactivated eggs following exposure to gamma (gamma), X-ray or UV irradiation (haploid androgenesis) and by restoration of
diploidy by suppression of mitosis using a pressure or thermal shock. The conditions for the genetic inactivation of the maternal
genome in the European sea bass (Dicentrarchus labrax L.) were explored using different combinations of UV irradiation levels
and durations. UV treatments significantly affected embryo survival and generated a wide range of developmental

Influence of residual stresses and geometric imperfections on the elastoplastic collapse of cylindrical

Provedor de dados: 5
Autores: Le Grognec, Philippe; Casari, Pascal; Choqueuse, Dominique.
The buckling problem of a circular cylindrical shell has long been widely investigated due to its great importance in the design of
aerospace and marine structures. Geometric imperfections and residual stresses are inevitable in practice and have been so far
frequently considered in analytical and numerical predictions. But little attention has been paid until now on the combined
influence of such initial defects on the critical and often unstable response of such elastoplastic structures. In this paper, a shell
finite element is designed within the total Lagrangian formulation framework to deal with the elastoplastic buckling and
post-buckling of thin cylindrical tubes under external pressure and axial compression. A specific experimental process will be...

The compilation of results obtained on three giant piston cores from the Whittard, Shamrock and Guilcher turbidite levees reveals

Autores: Sarafanov, Artem; Falina, Anastasia; Mercier, Herle; Lherminier, Pascale; Sokov, Alexey.
Recent decadal changes (1955-2007) in the baroclinic transport (TBC) of the Deep Western Boundary Current (DWBC) carrying
the Greenland-Scotland overflow-derived waters along the East Greenland slope are quantified from a set of hydrographic
sections in vicinity of Cape Farewell. The updated historical record of TBC shows clear decadal variability (+/- 2-2.5 Sv) with the
transport minima in the 1950s and mid-1990s, maximum in the early 1980s and moderate-to-high transport in the 2000s. Since the
mid-1990s, the DWBC TBC has increased by similar to 2 Sv (significant at the 99.9% level), which constitute similar to 20% of

we estimate the variability of the core properties of a variety of Subpolar Mode Water (SPMW) observed on the eastern flank of
the Reykjanes Ridge. This SPMW acquires its core properties in the winter mixed layer along the eastern side of the Reykjanes

an agroecosystem is essential for risk assessment and policies concerning the containment of genetically modified crops and their

An index to distinguish surface and subsurface intensified vortices from surface observations

In this study, we first show that it is difficult to reconstruct the vertical structure of vortices using only surface observations. In
particular we show that the recent SQG and ISQG methods systematically lead to surface intensified vortices and those subsurface
intensified vortices are thus not correctly modelled. We then investigate the possibility to distinguish between surface and
subsurface intensified eddies from surface data only, using the sea surface height and the sea surface temperature available from
satellite observations. A simple index, based on the ratio of the sea surface temperature anomaly and the sea level anomaly, is
proposed. While the index is expected to give perfect results for isolated vortices, we show that in a complex...

In late 2007, two massive icebergs, C19a and B15a, drifted into open water and slowly disintegrated in the southernmost Pacific
Ocean. Archived acoustic records show that the high-intensity underwater sounds accompanying this breakup increased ocean
noise levels at mid-to-equatorial latitudes over a period of ∼1.5 years. More typically, seasonal variations in ocean noise, which
are characterized by austral summer-highs and winter-lows, appear to be modulated by the annual cycle of Antarctic iceberg drift
and subsequent disintegration. This seasonal pattern is observed in all three Oceans of the Southern Hemisphere. The life cycle of
Antarctic icebergs affects not only marine ecosystem but also the sound environment in far-reaching areas and must be...

The influence on the feeding physiology (clearance, filtration, ingestion, absorption) of the Japanese oyster Crassostrea gigas of
low concentrations of suspended particulate matter (SPM ranging from 2 to 20 mg.l-l) and high food quality (mean organic
fraction =54 %) was studied in the laboratory. Experimental diets were made up with three strains of the "blue diatom" Haslea
ostrearia, which is responsible of the greening of oyster-ponds. The strains were characterized by different sizes (48, 65 and 98
µm respectively) but possessed the same density and biochemical composition. Clearance rate was found constant at 2.2 1.h(-l).g-l

Autores: De Decker, Sophie.
The New-Caledonian shrimp industry is based on the controlled reproduction of the shrimp Litopenaeus stylirostris, a species
which was introduced in the 80s. The major difficulty to which the industry has been faced for 10 years is the occurrence of the
“Syndrome 93”, which corresponds to mortality phases when the temperature falls down in April-May-June. This mortality is
associated to the pathogenic bacteria Vibrio penaecida. An experiment of genetic selection based on the criterion ofsurvival to
Syndrome 93 has been conducted at the Laboratory of Aquaculture of New Caledonia. The 3rd selected generation had
demonstrated very encouraging results (survival rates improved by around 20% in experimental infections with V. penaeicida).

Sea-surface temperature (SST) estimates for the last 10,000 years have been derived from foraminiferal fauna variations in ten
cores from the Mediterranean Sea. For the eastern cores, modern analogs of fossil assemblages are found in the eastern
Mediterranean Sea. In the Alboran and Tyrrhenian Seas, the bet analogs originate from modern fauna located either in the western
Mediterranean Sea or in the North Atlantic Ocean. During the last sapropel event, centred at about 8,000 years B.P., SSTs were
similar to present in the eastern basin, whereas they were colder than today by about 1.5 degrees C in the Alboran Sea and 2.5

Provedor de dados: 5
Autores: Desvignes, Thomas; Nguyen, Thaovi; Chesnel, Franck; Bouleau, Aurelien; Fauvel, Christian; Bobe, Julien.
Retinitis pigmentosa 2 (RP2) gene is responsible for up to 20% of X-linked retinitis pigmentosa, a severe heterogeneous genetic
disorder resulting in progressive retinal degeneration in humans. In vertebrates, several bodies of evidence have clearly
established the role of Rp2 protein in cilia genesis and/or function. Unexpectedly, some observations in zebrafish have suggested
the oocyte-predominant expression of the rp2 gene, a typical feature of maternal-effect genes. In the present study, we investigate
the maternal inheritance of rp2 gene products in zebrafish eggs in order to address whether rp2 could be a novel maternal-effect
gene required for normal development. Although both rp2 mRNA and corresponding protein are expressed during oogenesis,

Autores: Jean, Claire; Bourjea, Jerome; Jouen, Emmanuel; Taquet, Marc.
Stock structure of swordfish (Xiphias gladius Linnaeus, 1758) from four areas of the South West Indian Ocean was conducted
using Restriction Fragment Length Polymorphism (RFLP) on mtDNA control region and six amplified microsatellite loci. No
significant differences were found among the four locations using either molecular technique. Most variability was found within
populations, with only a small proportion of variation among samples, suggesting a unique stock of swordfish in the South West
Indian Ocean. The sample size of this study is too small to reveal significant structure among the sampling locations. These results
are baseline for a future larger scale project in the whole Indian Ocean.

Is there a continuous Subtropical Front south of Africa?

A 14.3 year series of weekly absolute sea surface height (SSH) and associated geostrophic velocities is used for a study of the

confirms a two-stepped transition in both the southeastern Atlantic Ocean (the Northern and Southern Subtropical fronts (NSTF,
SSTF)) and southwestern Indian Ocean (the Agulhas Front and SSTF), as proposed previously from hydrographic data. An
additional front associated with westward flow north of the NSTF is indicative of a partial eastern closure of the South Atlantic

Examination of the GLOMAR CHALLENGER cores in the Mediterranean Sea (Leg 13) enables us to distinguish three main
lithological units in the Neogene series. The lower unit is composed of blue marls with a poor, or dwarfed, fauna. The marls are of
Langhian, Serravalian and Tortonian age, and are very similar to the blue marls of the same age known on land (in the Rhône
basin, Vienna Basin, the Panonic Basins, etc.). This suggests that the Vindobonian Tethys received a uniform type of

In this paper we compare the simulated Arctic Ocean in 15 global ocean–sea ice models in the framework of the Coordinated
Ocean-ice Reference Experiments, phase II (CORE-II). Most of these models are the ocean and sea-ice components of the coupled
climate models used in the Coupled Model Intercomparison Project Phase 5 (CMIP5) experiments. We mainly focus on the
hydrography of the Arctic interior, the state of Atlantic Water layer and heat and volume transports at the gateways of the Davis

Arctic Ocean between the models, and generally large differences compared to the observed temperature at intermediate depths.

How does abundance scale with body size in coupled size-structured food webs?

Autores: Blanchard, Julia L.; Jennings, Simon; Law, Richard; Castle, Matthew D.; Mccloghrie, Paul; Rochet, Marie-joelle;
Benoit, Eric.
Widely observed macro-ecological patterns in log abundance vs. log body mass of organisms can be explained by simple scaling
theory based on food (energy) availability across a spectrum of body sizes. The theory predicts that when food availability falls
with body size (as in most aquatic food webs where larger predators eat smaller prey), the scaling between log N vs. log m is
steeper than when organisms of different sizes compete for a shared unstructured resource (e.g. autotrophs, herbivores and
detritivores; hereafter dubbed 'detritivores'). In real communities, the mix of feeding characteristics gives rise to complex food
webs. Such complexities make empirical tests of scaling predictions prone to error if: (i) the data are not disaggregated in...

Apoptosis is a fundamental feature in the development of many organisms and tissue systems. It is also a mechanism of host
defense against environmental stress factors or pathogens by contributing to the elimination of infected cells. Hemocytes play a
key role in defense mechanisms in invertebrates and previous studies have shown that physical or chemical stress can increase
apoptosis in hemocytes in mollusks. However this phenomenon has rarely been investigated in bivalves especially in the flat
oyster Ostrea edulis. The apoptotic response of hemocytes from flat oysters, O. edulis, was investigated after exposure to UV and
dexamethasone, two agents known to induce apoptosis in vertebrates. Flow cytometry and microscopy were combined to

The dwindling of the stocks of some marine animals traditionally fished is driving the producers to consider the exploitation of
species which were seen as of lesser interest up to now. Among the latter, cephalopods hold a specific position. In the first place,
they are not a new resource so to speak, having been eaten in Asian and Mediterranean countries for a long time, and, above all,
they've been the object of a growing interest for a few years now. It is encouraging to see that this tendency is very distinct in our
country where it can be thought that producers and consumers are now aware of the value of this abounding species. The actions
aimed at optimising their exploitation are thus facilitated but they suffer from the imprecision of the...

la pêche en proportion. Si, au contraire, la vitesse est trop grande, le chalut refoule de l'eau en avant de sa gueule et rejette ainsi le
poisson qui serait disposé à y entrer ; il passe également trop vite pour déloger les poissons plats tels que soles et turbots qui

Comparé aux techniques modernes de conservation qui mettent en oeuvre des appareils coûteux et un personnel pourvu de

jetées sur une morue tranchée suffisent à
prolonger très sensiblement sa durée de conservation. Mais que se passe-t-il
exactement? Nous sommes loin de le savoir dans le détail. Nous savons que le sel pénètre dans le poisson par capillarité et par
osmose et provoque la turgescence des cellules jusqu'à ce que l'équilibre électrostatique du tissu se trouve rompu. Le muscle qui
contient alors 9 à 10 % de sel laisse échapper une partie de son eau de constitution et devient impropre au développement des

REMORA. Résultats de l'année 93
Provedor de dados: 5
Autores: Littaye-mariette, A.
What is REMORA? REMORA −REseau MOllusques du département Ressources Aquacoles−
(Aquaculture Resources Department Mollusc Network) is a surveillance network dedicated to the growth of hollow oysters
Crassostrea gigas. In the past and in most production areas, observations were made on a regular basis. In 1993, homogenising
experimental protocols between the different laboratories involved was decided, as well as using a common initial oyster batch,
therefore organizing a network covering all of the French coasts. This network aims at providing, each year, the production's basic
characteristics found in main oyster beds (growth reference). It also better characterizes variations and shows potential tendencies.

Autores: Post, A.
On the basis of geographical distribution and morphological analysis of the Atlantic Howella , two subspecies of H. brodiei have
been established, H. brodiei brodiei for the IndoPacific and H. brodiei atlanlica for the tropical and boreal Atlantic. H. sherborni
has been recognized as a separate species, probably distributed circumglobally in southern Ocean but presently recorded only
from the South Atlantic, the central South Pacific and from off southern and south-eastern Australia respectively. H. b. atlanlica
and H. b. brodiei are distinct by having 3 scale rows between the lateral line and the origin of the second dorsal fin, while H.
sherborni has 4 scale rows there. H. sherborni is in geographical contact with the two subspecies while H. b. brodiei...

INTRODUCTION - L'âge des huîtres d'élevage est paradoxalement mal connu. En effet, la biologie des huîtres ainsi que les
techniques culturales, consistant en des transferts successifs de bassin à bassin, de lotissements des animaux en fonction de leur
taille, ont pour effet de compliquer voire de rendre impossible l'évaluation des cohortes composant les populations en élevage. La
présente étude se donne pour but de répondre aux questions suivantes : - donner l'âge des huîtres composant un échantillon en
provenance d'un site d'élevage connu; - déceler une différence d'origine; - reconnaître l'origine et l'''histoire'' des huîtres. Les
méthodes classiques d'ageage des mollusques sont appliquées: lecture externe, coupes, recherches de structures périodiques...

New Perspective On The Haplosporidian Parasites Of Molluscs
Provedor de dados: 5
Autores: Arzul, Isabelle; Carnegie, Ryan B.
The protist phylum Haplosporidia comprises over 40 described species with representatives infecting a range of mollusc hosts,
including several ecologically and economically significant pathogens. Continuing exploration of haplosporidian diversity has
added ten new species in recent years and brought the phylogenetics of the group into somewhat clearer focus, with monophyletic
Bonamia and Minchinia lineages continuing to be supported. However, the addition of new sequences to phylogenetic analyses
has left the paraphyletic genus Haplosporidium’s picture less resolved. It is not clear that even two genera will be enough to
accommodate the species presently drawn to the Haplosporidium regions of the haplosporidian tree. In this review, we summarize

Initiatives for the sustainable development of aquaculture have so far focused on the production of codes of conduct, of best
management practices, of standards etc., most of which have been developed by international organisations, the industrial sector
and non governmental organisations. They were, to a large extent, produced using a "top down" process and inspired by models
from intensive industrial shrimp and sea fish farming (mainly salmon). However, most of global aquaculture production comes
from small-and medium-sized farms, essentially in Asia which contributes 92% of the total world aquaculture production volume.
The objective of this article is to define the contours of systemic typologies that are able to express the sustainability conditions...

Diagenetic evolution of the dop facies from the atlantis-ii-deep (red-sea) - evidence of early
hydrothermal activity
Provedor de dados: 5
Autores: Anschutz, P; Blanc, G.
The 23,000 year old sediments of the Atlantis II Deep rest on a basaltic substratum and are overlaid by a dense and hot brine pool.
The facies of the lower sequence of the West basin consists essentially of bioclastic and detrital particles (DOP facies). The
primary calcite and aragonite of planktonic tests of the DOP facies have been transformed into Ca-, Mg-, Mn-, and Fe-carbonate
solid solutions. Pyrite amounts to about 1-2% (wt) at the bottom of the sedimentary series, and as much as 20% (wt) in the upper
part of the sequence. These high iron - and manganese - earing minerals are the product of early diagenetic processes in an
environment favourable to bacterial activity, to which biogenic and detrital particles, organic matter, and iron and manganese...

Oysters are sessile filter feeders that live in close association with abundant and diverse communities of microorganisms that form
the oyster microbiota. In such an association, cellular and molecular mechanisms have evolved to maintain oyster homeostasis
upon stressful conditions including infection and changing environments. We give here cellular and molecular insights into the
Crassostrea gigas antimicrobial defense system with focus on antimicrobial peptides and proteins (AMPs). This review highlights
the central role of the hemocytes in the modulation and control of oyster antimicrobial response. As vehicles for AMPs and other

Autores: Stevenson, Angela; Mitchell, Fraser J. G.; Davies, Jaime S.
Predation and competition are highly influential factors determining space use in foraging animals, and ultimately contribute to
the spatial heterogeneity observed within habitats. Here we investigated the influence of competition and predation on space and
resource use via continuous video transect observations – a tool that has not previously been employed for this purpose. This
study therefore also evaluates video data as a pragmatic tool to study community interactions in the deep sea. Observations were
compiled from 15 video transects spanning five submarine canyons in the Bay of Biscay, France. Substrate choice, positioning on

In 1999, the world aquaculture production of molluscs was estimated at 9.4 million tonnes which represents approximately a 23%
contribution to the global aquaculture production. Aquaculture of molluscs has been growing at an average annual rate of 11%
over the past decades, although some activities - such as aquaculture of pectens or abalones - were growing even more rapidly. In
many countries, there is a significant mollusc aquaculture, traditionally based on wild stocks. However, these natural populations
frequently do not fulfil market demand, because of low value of the product, over-fishing of the resource and/or mass mortality
outbreaks caused by diseases. A frequent answer to this situation has been the introduction of new stocks or new species in...

Becheler, Ronan; Madin, Joshua S.
Most marine organisms disperse via ocean currents as larvae, so it is often assumed that larval-stage duration is the primary
determinant of geographic range size. However, empirical tests of this relationship have yielded mixed results, and alternative
hypotheses have rarely been considered. Here we assess the relative influence of adult and larval-traits on geographic range size
using a global dataset encompassing 590 species of tropical reef fishes in 47 families, the largest compilation of such data to date
for any marine group. We analyze this database using linear mixed-effect models to control for phylogeny and geographical limits
on range size. Our analysis indicates that three adult traits likely to affect the capacity of new colonizers to survive...

Influence of phytoplankton diversity and community structure on oyster reproduction (Arcachon
Bay, France)

Arcachon Bay is one of the most important spat-supplying area for the French oyster production. During the last 16 years, the
local economic activity of spat production has been threatened recurrently by a high interannual variability of seed harvesting.
This threatened spat production was attributed to reproductive problems highlighted by both a delay in oyster spawning and a
decrease of small larvae abundances since 1995. Recent works showed that these two reproduction indices seem closely related to
climate change that might controls the phytoplankton communities of the Bay. Food availability in term of quantity and quality
appears thus as a serious track to understand the reproductive problems of oyster in the Arcachon Bay. The aim of this work was...

(CS)-C-137 inventory in sediment near the Rhone mouth: role played by different sources
Provedor de dados: 5
Autores: Charmasson, S.
The low tidal range of the Mediterranean Sea and the high sediment load of the Rhone induce the formation of an important
submarine delta. The Cs-137 inventory in sediment on a 480 km(2) area near the Rhone mouth reached 19.6 TBq in 1990. The
spatial distribution of both sediment accumulation rates and (CS)-C-137 concentrations in this area confirm the existence of a
spatially well-delimited zone, i.e. the prodelta, where both parameters are the highest. Thus, 40% of the total amount of Cs-137
stored in this 480 km(2) area was found within the prodelta (30 km(2)) in the close vicinity of the river mouth. This attests to the
efficiency of the (CS)-C-137 trapping by the prodelta sediments. A study on the part the different (CS)-C-137 sources in the...

Repairing fishing nets involves mending nets that have suffered damage. This work is done directly on board the trawler or in the
boat hangar. Among the subjects dealt with in works on fishing nets published in France up to now, fishing net repair has only
been briefly addressed due to the apparent simplicity of this activity, particularly for gillnets. However, the development of
trawling and the changes in shape that trawls have undergone in general have increased the difficulties of repairing these nets.
These difficulties have been and are still met as they arise by technicians in net rigging factories or by fishermen themselves.
However, problems arise, as we have witnessed, not only in daily operations, but also during training courses for young...

Blind submarine seismic deconvolution for long source wavelets
Provedor de dados: 5
Autores: Nsiri, Benayad; Chonavel, Thierry; Boucher, Jean; Nouze, Herve.
In seismic deconvolution, blind approaches must be considered in situations where reflectivity sequence, source wavelet signal,
and noise power level are unknown. In the presence of long source wavelets, strong interference among the reflectors
contributions makes the wavelet estimation and deconvolution more complicated. In this paper, we solve this problem in a
two-step approach. First, we estimate a moving average (MA) truncated version of the wavelet by means of a stochastic
expectation-maximization (SEM) algorithm. Then, we use Prony's method to improve the wavelet estimation accuracy by fitting
an autoregressive moving average (ARMA) model with the initial truncated wavelet. Moreover, a solution to the wavelet
initialization problem in the SEM...

Remarques sur la sexualité de la sardine, clupea pilchardus walb.
Provedor de dados: 5
Autores: Belloc, G; Desbrosses, P.
During our studies on the biology of the sardine from the French Atlantic coast, over the 1929 fishery, we noticed some
specificities in this fish's sexuality. In particular, we observed some differences between the male and female individuals from
each of the studied batches. These differences are of the same order and show a constant character. Some sexual dimorphism facts
tally with the fragmentary observations of L. Fage on the sardines from the entire French coast, Arné on the individuals caught
South of the Gironde, and Le Gall on the celans from the English Channel. The observations we made can be used as a basis for a
global study on the sexuality and the dimorphism in the sardine.

Effect of an invasive mollusc, American slipper limpet Crepidula fornicata, on habitat suitability for

Autores: Le Pape, Olivier; Guerault, Daniel; Desaunay, Yves.
This study describes the effect of an invasive mollusc, the slipper limpet Crepidula fornicata, on the distribution and abundance of
young-of-the-year sole Solea solea in coastal nursery areas, based on beam-trawl surveys in the Bay of Biscay (France) over a 3 yr
period (2000 to 2002). As habitat suitability for juvenile sole varies according to bathymetry and sediment structure, these factors
and the density of the slipper limpet were used as descriptors in generalised linear models of habitat suitability to characterise the
distribution of juvenile sole. The models were based on a delta distribution, coupling a binomial model testing for the presence of
juvenile sole with a log-normal distribution for density when juveniles were known to be present....

variables (depth, temperature) were examined in 1989-1990 on oyster population by using off-bottom culture. No significant
density effect was observed on the shell growth, which is described by using a seasonally oscillating function. In contrast, the
meat growth and the proximate biochemical composition were bath affected by the stacking density and the depth location. The
variability of the resulting effects was observed based on a seasonal trend. Different hypothesis mainly related tO environmental

An inverse model of the large scale circulation in the South Indian Ocean
Provedor de dados: 5
Autores: Sultan, Emmanuelle; Mercier, Herle; Pollard, R.t.
An overview of the large-scale circulation of the South Indian Ocean (SIO) (10 degrees S-70 degrees S/20 degrees E-120 degrees
E) is proposed based on historical hydrographic data (1903-1996) synthesized with a finite-difference inverse model. The in situ
density, potential temperature and salinity fields of selected hydrographic stations are projected on the basis of EOFs. Then the
EOF coefficients (the projected values) are interpolated on the model grid (1 degrees in latitude, 2 degrees in longitude) using an
objective analysis whose spatial correlation functions are fitted to the data set. The resulting fields are the input of the inverse
model. This procedure filters out the small-scale features. Twelve modes are needed to keep the vertical structures...

Evaluation of microdiets versus live feeds on growth, survival and fatty acid composition of larval

Until recently, it was considered impossible to feed newly hatched marine fish species with a compound diet. Substituting a
compound diet for live prey was performed several weeks after hatching, depending on the species. Compound diets were well
ingested at the early stage but larvae died with a gut full of food, suggesting that larvae were unable to digest the compound diet.
The hypothesis was that younger larvae have insufficient digestive enzymes to thrive on compound diets, and that exogenous
enzymes, provided from live prey, are necessary for early stages. The organogenesis of marine fish larvae is not completely
achieved at hatching and histological studies have revealed that the anatomy of the digestive tract undergoes developmental
changes over...

Comparative analysis of phylogenetic and fishing effects in life history patterns of teleost fishes
Provedor de dados: 5
Autores: Rochet, Marie-joelle; Cornillon, Pierre-andré; Sabatier, Robert; Pontier, Dominique.
The effects of fishing on life history traits and life history strategies of teleost fishes are analysed by a new comparative method
that splits traits into an allometric part (size effect), an autoregressive phylogenetic component, and an environmental component
(fishing effect). Both intra- and inter-specific variation of age and size at maturity, fecundity, adult size and egg size are analysed
by comparing 84 populations of 49 species submitted to various fishing pressures. Two axes of life history diversification are
found among teleosts. One is the well-known slow-fast continuum separating short-lived and early maturing species (like
Clupeiformes) From longer-lived species that mature late relative to their size and spawn larger eggs (like salmonids...

Annually exploited communities from the Nile delta and two nearby lagoons (Manzalah and Edkou) were monitored from 1962 to
1989. The changes in community structure were analysed as a function of two events: fishing pressure growth (motorized fishing
vessels) which increased by a factor of 19 between 1952 and 1962; and the construction of the Aswan Dam, which was built
between 1965 and 1969, reducing the flow of the Nile by 90 %. Before the construction of the dam, increased sea fishing pressure
led to a decline in landings from 33,832 tons in 1962 to 8,522 tons in 1969, but with no structural change in the exploited
community. However, following completion of the dam in 1969, the community structure changed and a significant correlation

This paper reports the development of a sensor based on surface-enhanced Raman scattering (SERS) for analyses in sea-water.
Polycyclic aromatic hydrocarbons (PAHs) are targeted by these sensors and their detection in situ summons up chemical synthesis

Different kinds of substrates have been synthesized under variable experimental conditions to modify some parameters such as i)
gold shape, size and distribution and such as ii) chemical functionalization: (i) gold nanoparticles were prepared either by
chemical reduction of HAuCl4 or by physical deposition. (ii) Substrates were functionalized by hydrophobic films to allow

The invasive oriental shrimp Palaemon macrodactylus Rathbun, 1902 has considerably extended its distribution in transitional
waters along the Atlantic and Channel coasts of France during the period 2007-2010. The most probable method of a primary
introduction of this species is ballast waters, but passive transport by water currents is also a possible mechanism of colonization
(secondary introductions). Palaemon macrodactylus is a powerful invader of transitional waters and these new populations should
be monitored in the future to assess any consequences to native species.

Automated acoustic receivers are now widely used by biologists to study the behavior of fish. However, currently available
acoustic receivers require physical recovery of the units to download stored data. Such operation is often difficult in remote study
areas like in the open ocean. We present a new satellite-linked acoustic receiver (Vemco VR3-Argos) that allows downloading
data through a satellite uplink (Argos). The VR3-Argos can last up to one year, sending GPS positions and tag data at regular time

Commercial production of most bivalve species involves a phase of intermediate cultivation during which juveniles are grown
under protected conditions until they can be transferred to the final grow-out location. Consequently, the aim of this study was
investigating the effect of density on growth and survival in the intermediate culture of the razor clam Ensis arcuatus in raft. Two
series of experiments were performed, using in the first experiment two holding systems: 5-L plastic bottles and PVC cylinders,
both perforated, covered with a 1 mm mesh net to prevent razor clam escape and a 10-cm layer of coarse grained sand (300–1200

Provedor de dados: 5
Autores: Lassus, Patrick.
Comme chaque année,une synthèse régionale des perturbations côtières des écosystèmes phytoplanctoniques a été établie. Il ne
s'agit que des cas signalés à l'I.S.T.P.M. de Nantes. Afin de faciliter l'usage de ce document une présentation sous forme de
fichier a été retenue, les informations de base étant à peu près les mêmes que les années précédentes. J'attire l'attention sur
l'importance de la rubrique "documents disponibles" puisque c'est l'occasion à la fois de prendre note des observations effectuées
dans les laboratoires côtiers et de diffuser ces informations - après avis des auteurs - aux correspondants étrangers concernés par
les mêmes phénomènes (exemple récent du Phaeocystis). La présentation de ces synthèses, tous les deux ou trois ans, au...

Gas hydrates and gas bubbles were collected during the MARNAUT cruise (May-June 2007) in the Sea of Marmara along the
North Anatolian Fault system, Turkey. Gas hydrates were sampled in the western part of the Sea of Marmara (on the Western
High), and three gas-bubble samples were recovered on the Western High, the Central High (center part of the Sea of Marmara)
and in the Cinarcik Basin (eastern part of the Sea of Marmara). Methane is the major component of hydrates (66.1%), but heavier
gases such as C-2, C-3, and i-C-4 are also present in relatively high concentration. The methane contained within gas hydrate is
clearly thermogenic as evidenced by a low C-1/C-2 + C-3 ratio of 3.3, and carbon and hydrogen isotopic data (delta C-13(CH4) of
-44.1 parts per...

The boundary circulation along the European continental slope as transport vehicle for two calanid
copepods in the Bay of Biscay
Provedor de dados: 5
Autores: John, Hc; Mittelstaedt, E; Schulz, K.
The copepod fauna south-west of the British Isles includes a number of species which have their centre of distribution in the
subtropical or tropical Atlantic. Among these, some species appear to be faunistically linked with the Iberian continental slope or
slope waters even farther south along the NE Atlantic margin. It seems that these species reach their north-eastern range by means
of poleward-flowing currents. For example, Calanoides carinatus has deep-living resting stages and ascends to surface waters only
during its reproductive period, which is short at northern latitudes. Its main dwelling layers along the west Iberian continental
slope cover the poleward-flowing undercurrent and the Mediterranean outflow water underneath. Part of the poleward...

Il a été observé au cours de l'automne 1969 que des huîtres plates (Ostrea edulis L.) élevées et affinées dans des claires du bassin
de Marennes périssaient d'une façon anormale. Il s'agissait d'huîtres importées de Bretagne en avril 1969 : âgées de 2 ans, elles
avaient séjourné en parc, un an à Arcachon et 4 mois à Paimpol pour être ensuite immergées, à raison de 5/m2, dans des claires de
la région de La Tremblade. Par ailleurs des pertes asses sensibles ont été constatées sur des lots d'huîtres provenant d'Arcachon,
élevées également en claires à La Tremblade.

Du mois de janvier au mois de décembre 1977, 3 182 t de thon rouge (Thunnus thynnus Linné, 1758) ont été capturées par les
senneurs français de Méditerranée. De nombreuses données concernant le déroulement de cette campagne ont été réunies ainsi
qu'un échantillonnage représentant près des deux tiers de la capture totale. Ces informations revêtent un intérêt de premier plan
pour la connaissance de la démographie et de la dynamique des stocks de thon rouge. Elles ont pu être recueillies grâce à la

A physiological and biochemical approach to selecting the ideal diet for Ostrea edulis (L.) broodstock
conditioning (part A)
Provedor de dados: 5
Autores: Gonzalez-araya, Ricardo; Queau, Isabelle; Quere, Claudie; Moal, Jeanne; Robert, Rene.
To select the best microalgae for Ostrea edulis conditioning, four single species diets were fed to batches of broodstock, which
were then compared using physiological and biochemical approaches. Ingestion and absorption were first studied, showing that
Chaetoceros gracilis and Skeletonema marinoï were efficiently ingested (4.9–5.3 mg g−1 h−1) and absorbed (1.9–2.5 mg g−1
h−1) while Tetraselmis suecica led to the lowest physiological responses (0.36 and 0.12 mg g−1 h−1 respectively). When O.
edulis were fed any microalgae except T-ISO with only 79 mg g−1, gonads accumulated carbohydrates from 116 to 141 mg g−1
and the extent of accumulation depended on the species supplied in the order T. suecica<C. gracilis<S. marinoï. When
oysters were fed either...

Autores: Stanev, Ev; Friedrich, Hj.
Based on Levitus' (1982) data set, a combination of robust diagonstic and fully prognostic techniques is used to evaluate for the
Mediterranean Sea a climatology consistent with the physics of the GFDL-OGCM. Model experiments are carried out with 28
levels and with a horizontal resolution of DELTA-lambda = 1/3-degrees, DELTA-phi = 1/4-degrees. The model is forced
mechanically by wind stress taken from Hellerman and Rosenstein's (1983) data. Sea surface temperature and salinity are
prescribed from Levitus' (1982) data. Exchange flows in the Strait of Gibraltar are explicitly prescribed with 1.5 x 10(6) m3s-1.

Autores: Denis, Lionel; Grenz, Christian; Alliot, Elisabeth; Rodier, Martine.
Sediment-water dissolved inorganic nitrogen fluxes were measured monthly between November 1997 and January 1999 at two
sites on the continental shelf in the Gulf of Lions. Exchanges of ammonium, nitrate and nitrite were measured using whole core
incubations performed in the laboratory at in situ temperature and in the dark;. Stations were located on the shelf and near the
shelf break. Nitrate release represented the major part of total dissolved inorganic nitrogen fluxes (52-98%). At station Soft,
nitrate flux doubled from winter-early spring to August (4 to 10 mu mol m(-2) h(-1)). At station R, a large increase (2 to 14 mu
mol m(-2) h(-1)) was recorded between December 1997 and January 1998, after which flux tended to decrease. Ammonium flux

The big challenge of the next decade for the oceanic sciences is to adopt a multi-scale approach because of the strong nonlinearity
of the oceanic fluid. This can be undertaken only through numerical simulations with ultra-high resolution. Within this context,
the purpose of our projects is to fully explore two energetic dynamical oceanic regimes that have a major impact on the general
oceanic circulation: the mesoscale eddy regime at mid-latitudes and the equatorial regime. Expected results will help for the
configuration of realistic numerical simulations to be performed in 2006 by the OFES group on the Earth Simulator and they
should benefit to future climate models. These studies make use of the Primitive Equations model ROMS (Regional Ocean

This paper deals with the modelization of eddy-current measurements over combustion turbine blade coatings affected by
depletion of aluminum. First, we model the response of an eddy-current coil over a layered metallic structure with a top
over-aluminized coating by extending the analytical Uzal-Rose's model for one hyperbolic tangent conductivity profile to a
conductivity profile using two hyperbolic tangents for taking inward and outward depletion of aluminum inside the coating into
account. Results obtained with this model are similar to those obtained with a numerical multilayer model but with a reduced

Eutrophication of the Seine estuary and the Bay of the Seine is a crucial environmental issue for the management of ecosystems
and economic activities related to fisheries and tourism. A large quantity of nutrients, especially nitrogen, is brought to the coastal
zone by the Seine River, the main input of that area, but also by smaller rivers along the Normandy coast. This large delivery of
nitrogen leads to an imbalance between nitrogen (N), phosphorus (P) and silica (Si), which affects the growth of planktonic
organisms and can exacerbate the occurrence of harmful algal blooms (HABs). These events can be damaging for shellfish
fisheries, an important economic resource for the region. The study describes a new modelling chain coupling a riverine and a...

Bacterial infections have been suspected to be one cause of variable success in the incubation of turbot (Scophthalmus maximus)
eggs. The assessment of bacterial flora (bacterial environment) associated with ova, sperm and developing eggs was conducted
just at stripping gametes and during incubation. Gametes were collected in sterile conditions before fertilization. Eggs were held

Caractérisation de types hémocytaires dans l'hémolymphe de l'huître plate, Ostrea edulis, par
classification robuste
Provedor de dados: 5
Autores: Segretin, Angelique.
Les méthodes de classification sont largement utilisées en vision par ordinateur et reconnaissance des formes. La classification
floue a d'ailleurs montré de bonnes performances dans ces domaines, non seulement dans la reconnaissance de classes en volume,
mais aussi pour des formes fines, des droites, des courbes, et également des surfaces. L'idée est d'utiliser la classification
automatique pour tenter de caractériser des types hémocytaires présents dans l'hémolymphe de l'huître plate. Actuellement, trois
types d'hémocyte ont été définis, mais la difficulté d'établir un classement des cellules dans ces trois groupes, laisse penser qu'ils
ne sont pas exhaustifs. Différentes approches de classification ont été tentées sur des mesures morphométriques de...

1 - In the Thau lagoon (Southern Mediterranean Coast) the main anthropogenic pressure is represented by the urban development
in the watershed, whilst oyster and mussel farming represents one of the main economical activities in the region. 2 - During the
last decade, the increasing organic loads from watershed and urban settlements in the lagoon surroundings have caused a diffuse
contamination by faecal bacteria. Also toxic algal blooms have been occurring, impairing water quality with major impacts on
shellfish farming, fishery and bathing. 3 - In this study, indicators and scenarios identified for the lagoon have been integrated in a
Decision Support System (DSS) to evaluate the best solutions for reducing pressures and improving both water quality and...

Class II Microcins

Autores: Vassiliadis, Gaelle; Destoumieux-garzon, Delphine; Peduzzi, Jean.
Class II microcins are 4.9- to 8.9-kDa polypeptides produced by and active against enterobacteria. They are classified into two
subfamilies according to their structure and their gene cluster arrangement. While class ha microcins undergo no posttranslational
modification, class Jib rnicrocins show a conserved C-terminal sequence that carries a salmochelin-like siderophore motif as a
posttranslational modification. Aside from this C-terminal end, which is the signature of class IIb microcins, some sequence
similarities can be observed within and between class II subclasses, suggesting the existence of common ancestors. Their
mechanisms of action are still under investigation, but several class II microcins use inner membrane proteins as cellular targets,...

Fluctuations in the benthos of the western English Channel
Provedor de dados: 5
Autores: Holme, Na.
The most noticeable changes in benthos have been in the degree of penetration of species from the Celtic Sea into the western
Channel. There may also have been an indirect effect on beds of Ophiothrix fragilis off Plymouth through fluctuations in
populations of Luidia ciliaris , which preys on Ophiothrix . Other fluctuations in the benthos relating to sea temperature,
exceptionally cold winters, immigrant species, dinoflagellate blooms, and oil pollution incidents have mainly affected the eastern
Channel or inshore waters in the west, leaving offshores areas of the western Channel largely unaffected. There is now growing
evidence of harmful effects of heavy fishing gear on the offshore benthos in parts of the western Channel.

L'anchois (engraulis encrasicholus l.) des cotes d'Oranie
Provedor de dados: 5
Autores: Arrignon, Jacques.
Engraulis encrasicholus L. is a species that is captured all year long off the coasts of Algeria. The studied specimens measured
from 8 to 19 cm. The average total length is 14 cm. Throughout the year, the average monthly size does not vary (12.6 to 14.7 cm
for the entire species, 12.4 to 15.6 cm for bottom anchovies; the difference is greater for surface anchovies: 9 to 15 cm). During
summer, the average is the highest and the most constant. Sizes have different modes during winter and spring. Average lengths
are greater than those of the Atlantic specimens. This can be explained by the fact that the continental margin is narrower in the
Mediterranean Sea, so that anchovies can find trophic areas closer to the shore (J. FURNESTlN, 1950)....

A correct representation of the ice movement in an Arctic sea-ice-ocean coupled model is essential for a realistic sea-ice and
ocean simulation. The aim of this study is to validate the observational and simulated sea-ice drift for the Laptev Sea Shelf region
with in situ measurements from the winter of 2007/08. Several satellite remote-sensing data sets are first compared to mooring
measurements and afterwards to the sea-ice drift simulated by the coupled sea-ice-ocean model. The different satellite products
have a correlation to the in situ data ranging from 0.56 to 0.86. The correlations of sea-ice direction or individual drift vector
components between the in situ data and the observations are high, about 0.8. Similar correlations are achieved by the...

Risk, market imperfections and the growth of an aquacultural firm
Provedor de dados: 5

(Not controled OCR) Economic literature is replete with discussions of risk, market imperfections and firm growth ; often as
separate topics. A discussion of risk must inevitably mention Frank Knight's classic contributions to the topic and his dichotomy
between risk and uncertainty. Subsequent work has blurred this distinction by introducing subjective probability and expected
utility maximization. Subsequent work has also shed doubt on the validity of the expected utility hypothesis in willingness to pay
gambles and yet sustained it in the context of aggregate market behavior and "testable hypotheses" (Knez, et al, 1985). to this vast
and complex literature we do not aspire to contribute much that is new. Instead we will attempt to apply concepts to a...

We examined phytoplankton community responses to natural iron fertilisation at 32 sites over and downstream from the
Kerguelen Plateau in the Southern Ocean during the austral spring bloom in October-November 2011. The community structure
was estimated from chemical and isotopic measurements (particulate organic carbon - POC; C-13-POC; particulate nitrogen -PN;
N-15-PN; and biogenic silica - BSi) on size-fractionated samples from surface waters (300, 210, 50, 20, 5, and 1 mu m fractions).
Higher values of C-13-POC (vs. co-located C-13 values for dissolved inorganic carbon -DIC) were taken as indicative of faster
growth rates and higher values of N-15-PN (vs. co-located N-15-NO3 source values) as indicative of greater nitrate use (rather

We use the tracer and velocity fields of a climatological ocean model to investigate the ability of Argo-like data to estimate
accurately water mass movements and transformations, in the style of analyses commonly applied to the output of ocean general
circulation model. To this end, we introduce an algorithm for the reconstruction of a fully non-divergent three-dimensional

validation of the technique consists in comparing the resulting pathways for Antarctic Intermediate Water in the South Atlantic
Ocean to equivalent reference results based on the full model information available for velocity and tracers. We show that the...

BACKGROUND The press juices resulting from a compacting operation on fish by-products were subjected to a depuration
treatment in order to reduce the high COD (120 g O2 L–1). The process included an initial de-particulation step by means of two
metallic filter cartridges of 465 µm and 250 µm, followed by concentration with a 200 nm ultrafiltration ceramic membrane. The
polishing efficiency of each unit was assessed in terms of COD and protein removal. RESULTS Dead-end metallic filtration of
the press waters reduced their suspended matter content by 28%, but achieved only 5.6% decrease in chemical oxygen demand
(COD), which suggested further processing by membrane ultrafiltration. The de-particulated stream was then subjected to
ultrafiltration for 8 h in...

Use of diatom motility features as endpoints of metolachlor toxicity

Autores: Coquille, Nathalie; Jan, Gwilherm; Moreira, Aurelie; Morin, Soizic.
Many recent ecotoxicological studies suggest a relationship between freshwater contamination and increasing abundances of
motile diatoms (potentially able to move). The capacity to escape would present advantages to species in polluted environments.
However, actual motility as a response to toxicants had not been described and required experimental validation. We designed a
specific experiment to assess how a field-isolated diatom (Gomphonema gracile) distributes energy to in situ resistance (increased
population growth or photosynthesis) and escape (behavioral changes), when exposed to increasing concentrations of the
herbicide metolachlor. We report here the dose-time dependent responses of G. gracile populations. They coped with low

Is the Portuguese oyster Crassostrea angulata in Southern Europe endangered by the expansion of the
Pacific oyster C. gigas?
Provedor de dados: 5
Autores: Batista, Frederico; Boudry, Pierre; Lapegue, Sylvie; Heurtebise, Serge; Monteiro, C. C.
The Portuguese oyster, Crassostrea angulata, was introduced from Portugal to the French Atlantic Coast in the 1860s. C. angulata
quickly settled and expanded and leaded to the development of a new aquacultural industry in France. In the late 1960s, mortality
associated with the detection of an iridovirus, led to the wipe out of C. angulata from French Atlantic waters and to the massive
introduction of C. gigas to sustain production. In Southern Europe, similar symptoms were also observed in natural stocks of C.
angulata from Sado River (Portugal) and from the area of Cadiz (Spain). Nowadays, only very few «pure» populations of C.
angulata remain in southern Europe. These populations are potentially endangered by the current expansion of C. gigas...

Autores: Ehrhold, Axel; Blanchet, Aline; Hamon, Dominique.
Ifremer launched and coordinated the development of a strategy for the REBENT network (REseau BENThique) in 2000 to
monitor the aftermath of the "Erika" oil spill in December 1999. Its aim is to provide consistent baseline knowledge about coastal
benthic habitats and constitute a monitoring tool to detect changes at various scales over time and space. Sector-based seabed
habitat mapping in shallow water (< 50 m deep), is currently being conducted throughout Brittany's coastal waters through a
combination of geoacoustic marine systems and ground-truthing using biological grab sampling and seabed observations.
Sedimentological and biological results on Glenan area emphasize a great diversity of subtidal habitats and marine species
recognized. Sidescan...

Tag and recapture of European hake (Merluccius merluccius L.) off the Northwest Iberian Peninsula:
First results support fast growth hypothesis
Provedor de dados: 5
Autores: Pineiro, C; Rey, J; De Pontual, Helene; Goni, R.
In the first tagging experiment of European hake (Merluccius merluccius L.) conducted off the NW Iberian Peninsula to study
hake growth in the wild we released 527 live tagged individuals. The survival rate after capture and tagging was 58%. Mortality
during capture was positively correlated with depth of capture and negatively correlated with hake size. Fifteen months after
tagging, seven individuals (1.3%) had been recaptured with times at liberty ranging from 29 to 466 days. We provide the first
direct measurements of growth rates of Southern stock European hake in the wild and compare them with rates obtained from
tagging experiments in other regions and with rates derived from conventional otolith age reading. The mean somatic growth rate

The detailed interpretation of gravimetric surveys implies a good knowledge of the superficial geology, at least in specific spots
such as the basement's outcrops. We now have a geological sketch map as well as an estimate of the thickness of the sedimentary
series of the continental shelf off the coasts of Brittany. As a consequence, it is now possible to try and interpret the new map of
this region's gravimetric anomalies, based on the terrestrial and marine geological data.

Reunion island pelagic longline fishery characterization and standardization of albacore catch rates
Provedor de dados: 5
Autores: Coelho, Rui; Nikolic, Natacha; Evano, Hugues; Miguel, N; Santos; Bourjea, Jerome.
This document presents a characterization of the Reunion Island pelagic longline fishery, with a first description of the albacore
catches, catch-at-size, and the standardized catch per unit of effort (CPUE) series for the period 1992-2013. The spatial catch and
effort analysis revealed the major areas of operation of the fishery, and the identification of the fishery core region closer to the
Reunion Island area. The trends in the albacore catch-at-size were analyzed annually, and compared between the seasons and
regions of operation of the fishery. The albacore nominal CPUEs were calculated as number of fish per 1000 hooks, and were
standardized using Generalized Linear Models (GLMs). Four different modeling approaches were used (including Tweedie,...

Refined sea state analysis from an array of four identical directional buoys deployed off the Northern
Cornish coast (UK)
Provedor de dados: 5
Autores: Saulnier, Jean Baptiste; Maisondieu, Christophe; Ashton, Ian; Smith, George H.
This paper presents an analysis of sea states carried out from extended wave measurements realized near the Wave Hub wave
energy test facility in Cornwall (UK). The space directional information is derived from the spectro-directional processing of
time-domain data provided by an array of four independent SEAWATCH Mini II displacement buoys separated by an
approximate average distance of 500 m. It is observed that, even though the size of the array is small compared to the local wave
trains' length, the estimation of the directional spectra - using maximum entropy and likelihood methods - may sometimes exhibit
certain space variability over the array. It was also observed that the tidal currents variations produced a significant influence upon
the wave...

Introduction and objectives of the study: Understanding the operating modes of the coastline systems requires the study of the

of maintaining a close connexion between the physics, biology, geology and chemistry of the oceans is not new, and was for that
matter the subject of a note in the first report of the International Council for the Study of the Oceans (ICSS) in 1902 (Sverdrup et
al., 1954): ... it was seen from the beginning that the study of the physical conditions, of the chemical nature of the ocean waters,
of the currents, etc., was of the greatest importance for the investigation of the problems connected with life, that...

Une formulation parabolique pour la propagation en profondeur finie des ondes de gravité en surface
Provedor de dados: 5
Autores: Mordane, Soumia; Maroihi, Kamal L; Orbi, Abdellatif; Chagdali, Mohamed.
This paper deals with the parabolic formulation of propagation equations of gravity waves in surface in terms of angular capability
with respect to the privileged propagation direction. This parabolic formulation is obtained by splitting the Berkhoff equation
operator into two parabolic operators representing progressive and regressive wave propagation. The use of Pade approximants
permits to derive simultaneously parabolic equations for the transmitted waves and the reflected waves. Two well-known
reference examples, which represent the propagation of the wave when a caustic occur, are studied numerically and the results are
compared with those of the literature. (C) 2001 Ifremer/CNRS/IRD/Editions scientifiques et medicales Elsevier SAS.

The genus Pseudoscopelus Lutken, 1892 is easily distinguished from the other Chiasmodontidae by the presence of well-defined
rows of photophores. Until 2005, eight species were known. Pseudoscopelus scriptus was the first described by Lutken in 1892,
then P. sagamianus by Tanaka in 1908, P. stellatus by Beebe in 1932 and P. altipinnis by Parr in 1933. Later in 1934, Fowler
described three new species: P. microps, P. cephalus, and P. obtusifrons. These three species, known from only one specimen
each, have not been recorded since. Lastly, an easily distinguishable species, P. scutatus, was discovered by Krefft in 1971. In a

Provedor de dados: 5
Autores: Haines, K; Wu, Pl.
A model of the whole Mediterranean sea at 0.25 degrees x 0.25 degrees resolution has been run for ten years with a mean seasonal
cycle of forcing using NMC winds and a relaxation to NODC surface temperature and salinity. The winter season water formation
and dispersal in the model thermocline has been studied using isopycnal diagnostics and potential vorticity as a water mass tracer.
In the eastern basin Levantine Intermediate Water (LIW) is formed in the cyclonic Rhodes gyre and moves west in a continuous
mass, accumulating and mixing in the centre of the Northern Ionian. The LIW spreading path is identified both from the high
salinity and low potential vorticity values on the 28.8 isopycnal surface. Some LIW then spreads west and south towards Sicily,...

Calcification abnormalities linked to the appearance of a brown coloration of the internal shell layer are observed in scallops
Pecten maximus in the Brest roadsted. It is a widespread phenomenon in shallow waters (about 3 to 10 meters) sometimes
associated with an important boring parasitism at the ultimate stage of development. This brown color which can generate a

Local mutagenic impact of insertions of LTR retrotransposons on the mouse genome
Provedor de dados: 5
Autores: Desmarais, Erick; Belkhir, Khalid; Garza, John Carlos; Bonhomme, Francois.
Solitary LTR loci are the predominant form of LTR retrotransposons in most eukaryotic genomes. They originate from
recombination between the two LTRs of an ancestral retrovirus and are therefore incapable of transposition. Despite this
inactivity, they appear to have a substantial impact on the host genome. Here we use the murine RMER10 LTR family as an
example to describe how such elements can reshape regions of the genome through multiple mutations on an evolutionary time
scale. Specifically, we use phylogenetic analysis of multiple copies of RMER10 in rodent species, as well as comparisons of
orthologous pairs in mouse and rat, to argue that insertions of members of this family have locally induced the emergence of
tandem repeat loci as well as many...

In batch cultures of four Mediterranean strains (from France, Italy, and Spain) of Alexandrium catenella (Whedon et Kof.) Balech
growing on a daily light cycle, ammonium and urea uptake were estimated by the N-15 tracer technique. Ammonium uptake could
be described by Michaelis-Menten kinetics along a substrate gradient of 0.1-10 mu gat N.L-1 for the four strains, while two
different patterns were observed for urea uptake with Michaelis-Menten kinetics for one strain and linear kinetics for the others. In
all cases, an increase in uptake rates with time was noted over the daylight period. This trend led to a net increase in the maximum
uptake rate (V-max; for saturable kinetics) and in the initial slope alpha. For ammonium, V-max increased by a factor of...

1. Introduction: network organisation in 1997. The REMORA network - REseau MOIIusques du département Ressources
Aquacoles de l'Ifremer - (Ifremer's Aquaculture Resources Department Mollusc Network) has been evaluating, since 1993, hollow
oysters' growth (Crassostrea gigas) in major French oyster beds. In order to do so, it has followed up on a yearly basis the growth
of a unique oyster batch shared among different stations in the main French raising areas. Releasing takes place in February and

Apport des techniques spatiales à la connaissance des courants de surface-Application à l'océan
Antarctique
Provedor de dados: 5
Autores: Daniault, Nathalie.
Au cours des deux dernières décennies, l'accent a été mis, par la communauté scientifique internationale, sur l'importance des
interactions océan-atmosphère dans la genèse des phénomènes météorologiques, et sur la nécessité d'améliorer le réseau
d'observations en mer : Les bouées dérivantes ou ancrées, porteuses de stations automatiques de mesures, sont à l'heure actuelle
largement utilisées par les organismes météorologiques, pour combler les zones où les informations font défaut. La localisation de
ces bouées, et la transmission des données sont assurées par le système ARGOS, système embarqué à bord de satellites à orbites
polaires.

L'altération du poisson

Le présent travail a un objet essentiellement pratique : il consiste dans l'examen critique des méthodes susceptibles de renseigner
le plus exactement possible sur l'état de fraîcheur ou le degré d'altération du poisson de mer. En général, il n'est certes pas
expédient de recourir à des recherches de laboratoire pour reconnaître si un lot de poissons est propre à la consommation ;
l'observation des caractères organoleptiques peut suffire. Mais il existe tout de même des cas où il serait utile de disposer d'une
technique purement objective qui définisse la condition hygiénique du poisson d'une façon suffisamment rapide et précise.
D'ailleurs, plusieurs auteurs se sont déjà attachés à l'étude du problème qui va nous occuper. Pour le moment, il sera seulement...

Dynamics of an estuarine ecosystem - The Chesapeake Bay experience: Statistical approaches and
water quality patterns
Provedor de dados: 5
Autores: Alden, Rw.
A long-term water quality monitoring program has been established in the Virginian waters of the Chesapeake Bay. To date, over
eight years of data have been analyzed to characterize spatio-temporal patterns and long-term trends in water quality.
Complementary multivariate statistical procedures were employed to define spatial and seasonal patterns, while a series of
non-parametric trend analyses were used for determining overall, site-specific, and season-specific long-term trends for water
quality variables in the tributaries and mainstem of the Bay. Particular attention was focused on determining the effect of river
flow on the trends, because flow rates in some of the tributaries have changed dramatically since the beginning of the monitoring
program....

Genetic improvement of hatchery propagated bivalve stocks : prospects and constraints
Provedor de dados: 5
Autores: Boudry, Pierre.
To date, the most significant genetic improvement for the production of Pacific oyster (Crassostrea gigas) has been obtained
through the production of triploids, especially since the development of tetraploids. Quantitative genetics studies suggest that
significant gains, for disease resistance or other traits, could be obtained in diploids. However, the limited extent of
hatchery-propagation (versus natural recruitment) and/or various technical difficulties and biological characteristics of the species
have retarded the development of selective breeding programs. In the U.S.A., Australia and New Zealand, family-based selective
breeding programs have recently been initiated to improve growth, disease tolerance and yield. In Europe, where both natural

Is a management framework based on spawning-stock biomass indicators sustainable ? A viability
approach
Provedor de dados: 5
Autores: De Lara, Michel; Doyen, Luc; Guilbaud, Therese; Rochet, Marie-joelle.
Fisheries management agencies have to drive resources on sustainable paths, i.e. within defined boundaries for an indefinite time.
The viable-control approach is proposed as a relevant method to deal with sustainability. We analyse the ICES precautionary
approach (PA) by means of the notion of viability domain, and provide a mathematical test for sustainability. It is found that the
PA based on spawning-stock biomass (SSB) and fishing mortality (F) indicators is sustainable only when recruits make a
significant contribution to SSB. In this case, advice based upon SSB, with an appropriate reference point, is sufficient to ensure
sustainability. In all other cases, SSB is not a sufficient metric of stock productivity and must be complemented with other...

Renault, Tristan; Thomas-guyon, Hélène.
Estuaries and coastal areas are often subjected to much pollution, including pesticides and polycyclic aromatic hydrocarbons
(PAHs) produced by anthropic activities. Bay of Marennes-Oléron is an estuarine coastal zone in which there is a high level of
aquacultural production and this has adverse effects in aquatic organisms. In fact, PAHs, which are widely spread throughout
aquatic ecosystems, have a low polarity and so there is a clear tendency to bioaccumulate in marine organisms (1). The harmful
effects of such contaminants on the organism's immune system, leading to a decreased resistance to pathogens, is a relatively new
area of research and it still poorly understood. The aim of the present work was to detect the impact in vivo of PAHs on the

Fluctuating asymmetry and mortality in cultured oysters (Crassostrea gigas) in Marennes-Oleron
basin
Provedor de dados: 5
Autores: Frechette, Marcel; Goulletquer, Philippe; Daigle, Gaétan.
Japanese cupped oysters suffer summer mortality in many culture sites along the French Atlantic coast. To ascertain whether
mortality might be associated with morphological features of the shells, we estimated fluctuating asymmetry (FA) of
hatchery/nursery-produced oysters kept in culture bags in the intertidal. FA is defined as random variations from a perfect
symmetry plane (bilateral or radial) in some morphological trait. FA increases with disruption of homeostasy during ontogeny and
has both genetic and environmental determinants. We found significant differences in FA between dead and live oysters in two of
our three study groups. Therefore, lack of developmental stability may be involved in the summer mortality syndrome of oysters.
We also found...

Comparaison de cinq indices alimentaires utilises dans l'analyse des contenus stomacaux

Autores: Rosecchi, E; Nouaze, Y.
Compound indices are often used in the analysis of fish stomach contents to characterize diet. Five of these indices, combining
two or three measures of prey importance: weight, abundance and frequency of occurrence, are mathematically compared in this
work. Data from a feeding study of sparid fish show that different indices can produce different results. Four classifications of
food, in terms of preferences, are applied to Sparidae, compared and discussed. A new method of classifying the prey of fish into
groups is proposed. It characterizes the main items in the diet, whatever feeding index is chosen for the analysis.

Effectiveness of LHRH and one of its analogs (LHRH-A = D-Ala super(6) ethylamide) on induction of ovulation and stimulation
of spermiation is reviewed here. LHRH was also combined with pimozide, an anti-dopaminergic agent, to try to cancel dopamine
inhibition of gonatotropin (GtH) release. LHRH-A alone (50 mu g/kg) did not initiate ovulation but only oocyte maturation. When
pimozide (10 mg/kg) and LHRH-A (50 mu g/kg) were combined, gonadotropic hormone secretion was significantly increased,
causing ovulation and stimulating spermiation. This combination advanced ovulation in trout. Trout egg quality was markedly
altered by the pimozide treatment; it remains to be tested in carp. In sea bass, LHRH-A was much more effective than LHRH, and

Cold seeps are among the most heterogeneous of all continental margin habitats. Abiotic Sources of heterogeneity in these
systems include local variability in fluid flow, geochemistry, and substrate type, which give rise to different sets of microbial
communities, microbial symbiont-bearing foundation species, and associated heterotrophic species. Biogenic habitats created by
microbial mats and the symbiotic species including vesicomyid clams, bathymodiolin mussels, and siboglinid tubeworms add an
additional layer of complexity to seep habitats. These forms of habitat heterogeneity result in a variety of macrofaunal and
meiofaunal communities that respond to changes in structural complexity, habitat geochemistry, nutrient sources, and

Long-term and millennial-scale climate variability in northwestern France during the last 8850 years

Vegetation and quantitative climate reconstructions from a northwestern France shelf core (VK0358Bis) show orbital and
suborbital climate variability for the last 8850 years in this region. A long-term cooling trend in summer temperatures, marked by
gradual temperate and humid forest decline, parallels cooling in Greenland and the decrease of mid-latitude summer insolation
reduction until at least 2000 cal. yr BP. At the long-term scale, the lowering in seasonal contrast revealed by vegetation changes
follows the increase of precession. Corylus woodlands spread at the expense of deciduous Quercus forest, between 8740 and 8390
cal. yr BP, linked with the high seasonality conditions that, counterbalancing the long-term astronomical forcing trend, were...

Several Vibrio species are known to be pathogenic to the Pacific oyster Crassostrea gigas. Survival varies according to pathogen
exposure and high mortality events usually occur in summer during gametogenesis. In order to study the effects of gametogenetic
status and ploidy (a factor known to affect reproduction allocation in oysters) on vibriosis survival, we conducted two successive
experiments. Our results demonstrate that a common bath challenge with pathogenic Vibrio splendidus and Vibrio aestuarianus on
a mixture of mature, spawning and non-mature oysters can lead to significant mortality. Previous bath challenges, which were
done using only non-mature oysters, had not produced mortality. Immunohisto-chemical analyses showed the affinity of Vibrio...

s(-1)) in neap and spring tide conditions. Turbulent kinetic energy, covariance, and logarithmic profile methods were used and
compared for the determination of shear stress. The c(TKE) coefficient value of 0.19 cited in the literature was confirmed. Shear
stress values were shown to decrease above mudflats from the mouth to the fluivial part of the estuary due to dissipation of the
tidal energy, from 1 to 0.2 N m-(2) for spring tides and 0.8 to 0.05 N m(-2) for neap tides. Flood currents...

où la vie a paru sur la terre, jusqu'à nos jours. Les questions, ensuite, des analogies qui ressortent des travaux d'anatomie comparée

Impact of the reproduction dynamics on genetic variation in the European flat oyster Ostrea edulis
Provedor de dados: 5
Autores: Lapegue, Sylvie; Taris, Nicolas; Lallias, Delphine; Bonhomme, Francois; Boudry, Pierre.
The European flat oyster (Ostrea edulis L.) is a marine bivalve whose natural geographical distribution ranges along the European
Atlantic coast from Norway to Morocco, in addition to the Mediterranean and Black Sea. The latest results obtained on the genetic
differentiation between these populations have led us to pursue studies at a finer scale, in order to estimate the effective number of
breeders and the temporal dynamics of reproduction and, more specially, recruitment. Several experiments were performed to
document (1) the variance in allele frequencies during a natural settlement period; (2) the paternal contribution to fertilization by
analyzing larvae sampled at the brooding stage within individual females; (3) the variance of individual...

Insights into Dynamics of Mobile Genetic Elements in Hyperthermophilic Environments from Five
New Thermococcus Plasmids
Provedor de dados: 5
Autores: Krupovic, Mart; Gonnet, Mathieu; Ben Hania, Wajdi; Forterre, Patrick; Erauso, Gael.
Mobilome of hyperthermophilic archaea dwelling in deep-sea hydrothermal vents is poorly characterized. To gain insight into
genetic diversity and dynamics of mobile genetic elements in these environments we have sequenced five new plasmids from
different Thermococcus strains that have been isolated from geographically remote hydrothermal vents. The plasmids were
ascribed to two subfamilies, pTN2-like and pEXT9a-like. Gene content and phylogenetic analyses illuminated a robust connection
between pTN2-like plasmids and Pyrococcus abyssi virus 1 (PAV1), with roughly half of the viral genome being composed of
genes that have homologues in plasmids. Unexpectedly, pEXT9a-like plasmids were found to be closely related to the previously
sequenced plasmid pMETVU01...

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

General introduction: The setting up of monitoring networks for coastal water quality of the REPHY type by IFREMER was taken
from a public health standpoint and fits broadly in with a principle of precaution regarding eating shellfish meant for human
consumption. The benefits to be compared with the costs of managing the REPHY network (estimated at FF7.4 million in 1995)
are therefore first and foremost the reduction of the risk of poisoning and can be captured by subtracting the sanitation costs that
are associated with them. Evaluating these direct benefits is, however, no easy task. The network leads in fact to the reduction of
occurrences of poisoning such that the epidemiological data on which such a calculation should be founded diminishes over
time....

Producing high quality cultured black pearls from Pinctada margaritifera is one of the major challenges for the "pearl oyster"
industry in French Polynesia. In order to assess donor effect on cultured pearl quality, wild Pinctada margaritifera originating from
the Tuamotu Archipelago were used in a duplicated grafting experiment. After 12 months of culture, nucleus retention was
assessed and seven pearl quality traits recorded on the 454 cultured pearls harvested from the experiment. The traits scored were
nacre thickness and pearl weight, surface defects, lustre, grade, and the colour components: 1) darkness of cultured pearl colour,
and 2) visual perception of colour class (bodycolor and/or overtone). Our results demonstrate for the first time that...

The long term effects of moderate elevation ORP (oxidation–reduction potential) around 300–320 mV on the growth,
hematological parameters and the ability of European seabass (Dicentrarchus labrax) to react against bacterial infection was
studied in recirculating aquaculture systems (RASs). Two RASs, one with a moderate ozonation (RAS-O3) and a control (RAS-C)
were used in this experiment. After 60 days, seabass reared in the RAS-O3 were more able to react against a Vibrio anguillarum
infection. It was in spite of the fact that seabass in the RAS-O3 showed decreased feed intake, feed conversion rate, growth rate
and modified hematological parameters compared with the fish in RAS-C. It is obvious that an ORP level of 300–320 mV is too

The diurnal fluctuations in solar irradiance impose a fundamental frequency on ocean biogeochemistry. Observations of the ocean
carbon cycle at these frequencies are rare, but could be considerably expanded by measuring and interpreting the inherent optical
properties. A method is presented to analyze diel cycles in particulate beam-attenuation coefficient (c(p)) measured at multiple
wavelengths. The method is based on fitting observations with a size-structured population model coupled to an optical model to
infer the particle size distribution and physiologically relevant parameters of the cells responsible for the measured diel cycle in
c(p). Results show that the information related to size and contained in the spectral data can be exploited to...

different ages ranging from 71 to 100 days post fertilization (dpf). Two different methods were tested for non-lethal tissue
sampling from each larva for DNA analysis: 1) using a sterile absorbent paper to sample mucus and/or epithelial cells by rubbing
the fish skin and 2) fin-clip of the bottom part of the caudal fin. Whatever the age of the larvae, the genotyping rate (at 12

Influence of diet assemblage on Ostrea edulis broodstock conditioning and subsequent larval
development
Provedor de dados: 5
Autores: Gonzalez, Ricardo; Mingant, Christian; Petton, Bruno; Robert, Rene.
In contrast with the Japanese oyster Crassostrea gigas and the Manila clam Ruditapes philippinarum, Ostrea edulis seed
production in the hatchery has been reported to be erratic, with sudden and unexplained larval and post-metamorphosis

and metamorphosis remain poorly understood. In addition, molluscan larval mortalities have been often associated with bacterial
contamination and flow-through techniques may help to overcome this problem. Both aspects have been considered in the present

Synthèse des études relatives à la modelistion de l'oxygène dissous dans l'estuaire de la Loire
Provedor de dados: 5
Autores: Thouvenin, Benedicte; Le Hir, Pierre; Maurice, Laurence; Romana, Louis-alexandre.
A la demande de l'Association pour la Protection de l'Environnement de l'Estuaire de la Loire, une étude sur le cycle de l'oxygène
dissous a été entreprise. Un modèle mathématique a été développé en plusieurs étapes, associé à des études sur le cycle de la
matière organique dans le système bouchon vaseux/crème de vase et au développement d'un modèle de transport sédimentaire.
Après la mise en place d'un modèle d'advection-dispersion dans l'estuaire, qui reproduit l'évolution de l'oxygène dissous sur un
cycle lunaire, l'application du modèle de transport sédimentaire a permis le perfectionnement du modèle d'oxygène dissous, qui
tient compte alors des variables particulaires aussi bien que dissoutes et décrit les variations de l'oxygène pendant cinq mois....

Les secteurs conchylicoles atteints par les efflorescences phytoplanctoniques toxiques sont fermés par l'Administration dès que le
taux de contamination devient dangereux pour la consommation humaine. Cette fermeture peut durer plusieurs mois empêchant
les conchyliculteurs de commercialiser leurs produits, ce qui a des conséquences économiques parfois graves. Il n'existe jusqu'à

Managing adequately the exploitation of commercial species subject to technical interactions is a key step towards the ecosystem
approach to fisheries. We evaluate here, using a bio-economic modelling approach building on the ISIS-Fish simulation platform,
the relative impact of total allowable commercial catches (TACC) and of taxes applicable to over-quota landings (deemed value)
on the sustainability of a selection of species exploited by the New Zealand hoki (Macruronus novaezelandiae) fishery. We
investigate some aspects of the hoki mixed fisheries, consisting of four fleets and nineteen metiers, by considering the technical
interactions between hoki and Southern hake (Merluccius australis). The dynamics of effort allocation were modelled using

Geographers have already been asking for a long time for studies to be carried out in the Arabic Sea. This Sea is bordered to the
North and to the West by Arabia and Africa; regions where it seldom rains and, consequently, with a very low alluvium input. It is
under the influence of the Red Sea through the Gulf of Aden, a basin more than 1 000 fathoms deep, with a low threshold of less
100 fathoms deep to the South. It is also under the influence of the Gulf of Oman, in which opens the very shallow Persian Sea
where an important drainage of the earth brought by the Tigris and the Euphrates takes place.

Designers and naval architects can legitimately feel concerned as to whether freak waves, of unexpected severity, are correctly
accounted for in current design practices and regulations. We describe here the main findings related to that phenomenon,
achieved mainly during the last decade by analysis of field data, theoretical developments and wave flume experiments. It appears
that conventional design methods are not actually challenged given the reliability levels required at present. Nevertheless, freak or
rogue waves remain a danger for operations and work at sea. The hypotheses for their generating mechanisms have still not been
validated in actual seas, and it is thus not possible to forecast either precisely any increase in their risk of occurrence...

Probiotics may have many effects on health and development of fish larvae. One of the most promising is related to spinal
conformation, though the mode of action is not clearly understood. The present study attempted to investigate the effects of two
strains of lactic acid bacteria on associated microbiota, histological development and gene expression. Sea bass larvae were fed
since 5 dph (day post hatch) with either a standard control diet (Diet C), or the same diet supplemented with Pediococcus
acidilactici MA18/5M (Diet P), or with an autochthonous strain of Lactobacillus casei (X2; Diet L). The two lactic acid bacteria
were incorporated in the diets at the levels of 106 and 107 CFU (colony forming units) g-1 in two consecutive experiments,...

Why carrying capacity models are useful tools for management of bivalve molluscs culture
Provedor de dados: 5
Autores: Heral, Maurice.
In areas where oyster or mussel culture is very intensive, declines of growth rate and decreases of survival rate have occurred. For
these reasons, plans have been proposed to regulate the cultivated biomasses in order to fit the carrying capacity of the different
ecosystems (Heral et al 1990; Heral, 1991). In areas where new aquaculture of molluscs is beginning, oyster or mussel farmers
need to know how large the extension of the culture could be and what the maximal densities should be in order to obtain the
maximum economic benefit. Furthermore, as mollusc cultures are developed in coastal areas, they are very susceptible to changes
in environmental conditions that can modify trophic relationships, or directly reduce growth rate, physiological...

monitoring and sanitary issues. In this study, we firstly developed a quantitative lateral flow immunoassay (LFIA) using
super-paramagnetic nanobeads for A. minutum whole cells. This dipstick assay relies on two distinct monoclonal antibodies used
in a sandwich format and directed against surface antigens of this organism. No sample preparation is required. Either frozen or

Plate tectonic and palaeomagnetic implications for the age of the Deccan Traps and the magnetic
anomaly time scale
Provedor de dados: 5
Autores: Molnar, Peter; Francheteau, Jean.
IF reconstructions of plate tectonic movement based on magnetic anomaly data are found to be inconsistent with reconstructions
based on palaeomagnetic data (see refs 1-3) it may indicate that one or more of the basic assumptions of the plate tectonic model
is erroneous : the age or identification of a particular anomaly may be incorrect, the pole positions or sample ages may be
unreliable or there may be an error in assessing plate rigidity. We present an example of inconsistency between the two types of
data and explore its implications for the chronology of magnetic reversals during the late Cretaceous and early Tertiary and for the
age of the Deccan Traps. [NOT CONTROLLED OCR]

A numerical model is developed to study the temperature effect on stability and phase transformation of gas-hydrate. The model
uses a mathematical formulation based on the enthalpy form of the conservation law of energy. The use of the enthalpy form
instead of the temperature form as often done in the literature has made the problem numerically simpler. The model is then
applied to describe the effect of sea bottom temperature variations on the stability of gas hydrate occurrences and on the seafloor
reflectivity in sediments of the Congo continental slope. Indeed, a migrating seafloor reflectivity front is observed on 3D seimic
images from two surveys performed 6 months apart and interpreted as a migrating gas hydrate stability zone. Seawater

Since the invention of the Petri dish, there have been continuous efforts to improve efficiency in microbial cultivation. These
efforts were devoted to the attainment for diverse growth conditions, simulation of in situ conditions and achievement of
high-throughput rates. As a result, prokaryotes catalysing novel redox reactions as well as representatives of abundant, but not-yet
cultured taxa, were isolated. Significant insights into microbial physiology have been made by studying the small number of
prokaryotes already cultured. However, despite these numerous breakthroughs, microbial cultivation is still a low-throughput

Climate change is perhaps the most pressing and urgent environmental issue facing the world today. However our ability to

Marine animals equipped with sophisticated oceanographic data loggers to study their behavior offer one solution to this problem
because marine animals range widely across the world's ocean basins and visit remote and often inaccessible locations. However,
unlike the information being collected from conventional oceanographic sensing equipment, which has been validated, the data

Global Interior Eddy Available Potential Energy Diagnosed from Argo Floats

By combining all Argo profiles for the period 2002 to present, a cumulative density function is constructed on a 3D grid of the

displacement, and Eddy Available Potential Energy (EAPE). EAPE is the analogue of the eddy kinetic energy, but for the
potential energy reservoir. Because it is essentially tied to the spatial struc- ture and magnitude of mesoscale activity, EAPE is an
important quantity that should be useful to evaluate eddy resolving/permitting model turbu- lence and circulation. Among other

A model coupling biological and hydrodynamical processes is used in order to study the influence of the amount of cultivated
oysters (Crassostrea gigas) on growth performance in the Bay of Marennes-Oléron. The model is based on an energetic budget
equation of a mean oyster and on a transport equation of particulate organic and inorganic matter through 12 spatial boxes.
Sensitivity analysis is performed and allows computation of the impact of the distribution of oysters among the boxes on the
growth performance of a mean oyster in each box. Il is shown that, mainly in the south of the bay, individual growth is affected by
the increase in the stock. The same approach also shows that the response of individual growth to the amount of natural benthic...

Oysters, like many other marine bivalves, are characterized by high fertility and low survival rates during the precocious stages.
Hatchery reproduction, realised in very different conditions than in their natural habitat (density, food, temperature, etc.), tends to
optimize the production of larvae and juveniles. As a consequence, slow growing larvae are systematically culled. Previous results
suggest the existence of a genetic variability linked to precocious development. Our approach consists in studying the
evolutionary process (genetic drift and selection) linked with hatchery reproduction. Thanks to microsatellite markers enabling us
to analyse the relatedness in "mixed" cultivated families, we studied the variability of breeding success in...

The aim of this study was to evaluate the importance of biotransformation of paralytic shellfish toxins during the detoxification
process in contaminated oysters. Mathematical models based upon the detoxification patterns of digestive gland and other tissues
were developed. It was demonstrated that biotransformations do not seem to play an important role in digestive gland or other
tissue detoxification kinetics with our data set. Moreover, different toxin transfers from digestive gland toward other tissues were
investigated. No significant transfer was highlighted in our data set. These first conclusions were drawn after comparing the
results obtained from 13 biotransformations and identifiable transfer scenarios. Finally, to determine a more robust...

Impact du changement climatique sur un écosystème estuarien : le Bassin de Marennes Oléron
Provedor de dados: 5
Autores: Soletchnik, Patrick.
L'huître est consommée dans le monde entier depuis des millénaires. Issue de gisements naturels, elle devient au cours des siècles
un produit d'aquaculture «traditionnelle» Contrairement à l'aquaculture dite «nouvelle», la conchyliculture, et en particulier
l'ostréiculture, échappe pour une grande part au contrôle des «travailleurs de la mer». Si l'homme gère les cheptels sur les sites
ostréicoles, l'alimentation de l'huître, elle, provient directement de son environnement. En poches et sur «tables» ou «à plat» sur le
sol, l'huître puise dans les particules organiques et le microphytoplancton en suspension dans l'eau de mer l'énergie nécessaire à sa
croissance et à sa reproduction.

1.This report presents the results of a field study conducted in the ECASA test site nOS in the Pertuis Breton, France. The site is
located on the Atlantic West coasts. It is open to the bay of Biscay, but is slightly protected against westerly winds. The bay has
been exploited by intertidal mussels culture for centuries. 2. Within the bay, mussels (Mytilus edulis) are cultivated either by the
traditional pole technique, around the bay or on longlines in the centre of the bay. The area occupied by these longline s represents
250 ha, and the resulting annual production is 1 000 tonnes of mussels. The average depth at mid tide is of 13.8 m. The sediment
is sandy, with a small fraction of mud. 3. The site is subject to several regular monitoring through the...

Lactic acid bacteria (LAB) were isolated from rotifer cultures in a marine hatchery to search for potential probiotics for marine
animals. Fifteen strains were first selected among a total of 55, according to antibacterial activity against Vibrio sp. Among eight
strains identified as Lactobacillus casei, four were highly adhesive, suggesting some ability for surface colonization. The other
strains were identified as Lactobacillus plantarum, Lactobacillus dextrinicus, and Leuconostoc sp. To validate probiotic potential,
Artemia were challenged against pathogenic Vibrio alginolyticus, with or without one of six selected LAB strains. The six strains
protected Artemia against the pathogen, to some extent on condition that nutrient enrichment was provided. La....

A number of marine mammal populations is currently threatened by their interactions with fisheries. The present study aimed to
provide insights into the severity of potential impacts of operational and biological interactions between top predators and
fisheries, in the Bay of Biscay region. Our approach was to modify an Ecopath with Ecosim (EwE) model describing the overall
structure and function of the ecosystem by including landings and discards of exploited stocks and estimations of the bycatch of
non-target compartments. Second, a set of ecological indices and a trophic level (TL)-based model (EcoTroph, ET) were derived
from the EwE model. ET was used to simulate the effects of increasing fishing pressure on the ecosystem and, more particularly,

Hormone-induced spawning of cultured tropical finfishes.
Provedor de dados: 5
Autores: Marte, C.
Commercially important tropical freshwater and marine finfishes are commonly spawned with pituitary homogenate, human
chorionic gonadotropin (HCG) and semi-purified fish gonadotropins. These preparations are often administered in two doses, a
lower priming dose followed a few hours later by a higher resolving dose. Interval between the first and second injections may
vary from 3-24 hours depending on the species. Variable doses are used even for the same species and may be due to variable
potencies of the gonadotropin preparations.

Experimental infections of Penaeus (Litopenaeus) stylirostris were performed with a Vibrio penaeicida strain (AM101) isolated in
New Caledonia from Syndrome 93 diseased shrimp. Cumulative mortalities resulting from intramuscular injection or immersion
of shrimp in bacterial suspensions demonstrated high virulence for this bacterial strain and suggested that V. penaeicida could be
the etiological agent of Syndrome 93. The median lethal dose (LD50) for AM101 was 1.3 x 104 CFU (colony forming units) ml-1
by immersion and less than 5 CFU shrimp-1 by intramuscular challenge, with mortality outbreaks at 48 and 22 h after challenge,

influence of accidental impact. The aim of this work is to study the dynamic response of tubular structures. Such structures find
many applications but the damage upon impact is not taken into account during their dimensioning. However, at the time of their
handling or in service the damage introduced by accidental impact can compromise their capacity to fulfill their function. The

Characterization of a gonad-specific transforming growth factor-beta superfamily member
differentially expressed during the reproductive cycle of the oyster Crassostrea gigas
Provedor de dados: 5
Autores: Fleury, Elodie; Fabioux, Caroline; Lelong, C; Favrel, P; Huvet, Arnaud.
Through differential screening between oyster families selected for high and low summer survival, we have characterized a new
transforming growth factor-beta (TGF-beta) superfamily member. This novel factor, named oyster-gonadal-TGF beta-like
(og-TGF beta-like), is synthesized as a 307 amino acid precursor and displays 6 of the 7 characteristic cysteine residues of the
C-terminal, mature peptide. Sequence comparison revealed that og-TGF beta-like has a low percentage of identity with other
known TGF-beta superfamily members, suggesting that og-TGF beta-like is a derived member of this large superfamily.
Real-time PCR (RT-PCR) analysis in different oyster tissues showed that og-TGF beta-like is specifically expressed in both male
and female gonads, at...

SLA and DHA agree remarkably well and, compared to previous studies, Argo dataset allows an improvement in the coherence
between SLA and DHA. Indeed, Argo data provides a much better spatial coverage of all oceans and particularly the Southern
Ocean, the use of an Argo mean dynamic height, the use of measured salinity profiles (versus climatological salinity), and the use
of a deeper reference level (1000 m versus 700 m). The large influence of Argo salinity observations on the consistency between

Previous studies have shown that magnetic resonance imaging is a very appropriate non-invasive technique for quantifying the
growth of somatic and gonadic tissues and sex determination in the Pacific oyster, Crassostrea gigas. Despite a thinner gonad,
harder to distinguish than that of the Pacific oyster, we showed in this study that it was possible to distinguish and quantify the
development of the gonad of the European flat oyster, Ostrea edulis, using a 3D MRI sequence with a suitable finer resolution.
Compared to T2-weighted images, theoretically the most appropriate for good anatomical description, T1-weighted images were
more suited to gonad observation. The gonad development was quantified by the number of voxels with higher grey level. Larvae

defined along shorelines from the significant wave height and a mean period. The empirical proportionality factor is found to
reproduce accurately the variations of free IG wave energy in coastal areas, where it was calibrated, and also has a good skill at
global scales. In the open ocean, the model is particularly verified for frequencies in the range 5 to 14 mHz for which ocean
bottom records are sensitive to the IG signal. The model captures between 30% and 80% of the variance in IG wave heights,
depending on...

As one of the busiest marine ecosystems in the world, the English Channel is subjected to strong pressures due to the human
activities occurring within it. Effective governance is required to improve the combined management of different activities and so
secure the benefits provided by the Channel ecosystem. In July 2014, a Cross-Channel Forum, entitled “Science and Governance
of the Channel Marine Ecosystem”, was held in Caen (France) as part of the INTERREG project “Promoting Effective
Governance of the Channel Ecosystem” (PEGASEAS). Here we use outputs from the Forum as a framework for providing
Channel-specific advice and recommendations on marine governance themes, including the identification of knowledge gaps,
which may form the foundation of future...

Subduction of a narrow slab of oceanic lithosphere beneath a tightly curved orogenic arc requires the presence of at least one
lithospheric scale tear fault. While the Calabrian subduction beneath southern Italy is considered to be the type example of this
geodynamic setting, the geometry, kinematics and surface expression of the associated lateral, slab tear fault offshore eastern
Sicily remain controversial. Results from a new marine geophysical survey conducted in the Ionian Sea, using high-resolution
bathymetry and seismic profiling reveal active faulting at the seafloor within a 140 km long, two-branched fault system near Alfeo
Seamount. The previously unidentified 60 km long NW trending North Alfeo Fault system shows primarily strike-slip
kinematics...

The aim of this study was to determine the nutritional effects of vitamin A and PUFA (including EPA and DHA) on sea bass
larvae development. An excess of vitamin A in the diet led to malformations affecting the cephalic region linked to an increase of
RARgama transcription and the loss of a vertebra when larvae were fed this diet from 8 days post hatch (dph) to 13 dph. A diet
containing an excess of PUFA disrupted the development of larvae vertebral column, deformities were correlated to a decrease of
RARalpha, RARgama, RXRalpha and BMP4 transcription and an additional vertebra appeared when larvae were fed this diet
from 8 dph to 13 dph. A diet containing 31 mg/kg of dry matter of vitamin A and between 1.1 and 2.3% of EPA + DHA allows

Trade-off between thermal sensitivity, hypoxia tolerance and growth in fish
Provedor de dados: 5
Autores: Roze, Thomas; Christen, Felix; Amerand, Aline; Claireaux, Guy.
One outcome of contemporary climate trends is that the involvement of hypoxia and heat tolerance in determining individual
fitness will increase in many fish populations. Large fish are believed to be more tolerant to hypoxia than small fish (Nilsson and
Ostlund-Nilsson, 2008) whereas thermal sensitivity is thought to decrease with body size (Clark et al., 2008). To better understand
the bases of inter-individual variation in environmental adaptation performance, the current study examined hypoxia and heat
tolerance in a fast growing (FGS; 288.3 +/- 14.4 g, 26.04 +/- 0.49 cm) and a slow growing (SGS; 119.95 +/- 6.41 g; 20.98 +/- 0.41

Autores: Froger, V; Lancelot, Y.
The western part of the Pacific plate, where the oceanic crust is of Jurassic age, has undergone exceptional volcanic activity
during the Cretaceous. It has produced numerous volcanoes (oceanic islands, guyots, seamounts) as well as very thick
accumulation of volcanogenic material in the deep basins. The Mesopac cruise of the R/V Jean Charcot in the Nauru Basin
obtained multichannel seismic profiles for the first time in these regions. This technique aimed at estimating the thickness of the
cretaceous volcanics and locating the top of the underlying Jurassic crust. The results, when compared with those of DSDP drill
holes, demonstrate that the abnormally shallow depth of the Nauru Basin results from an accumulation of flows and sills that

Autores: Guinand, B; Rolland, Jean-luc; Bonhomme, Francois.
Coastal and estuarine areas in the Bay of Biscay are essential nursery habitats for sole (Solea solea). Using three intronic markers,
we investigated patterns of genetic differentiation among cohorts of juveniles (0+, 1+, sub-adults) inhabiting four major nurseries
in the Vilaine and Loire river estuaries, the Pertuis d' Antioche strait, and the Gironde estuary. Genetic differentiation was not
significant for the age 0- and 1-groups, but was among sub-adult samples (theta(WC) = 0.017; P = 0.031). Hierarchical analyses
of genotypic frequencies by nested multivariate ANOVA using redundancy analysis indicated that northern nurseries of Loire and
Vilaine rivers had different patterns of genotypic variation with age than southern nurseries of the Pertuis d'...

The Medium Resolution Imaging Spectrometer (MERIS) launched in March 2002 and has been providing images since June
2002. Before its launch, we had implemented a method to improve its resolution by merging its images with Landsat Enhanced
Thematic Mapper images in order to preserve the best characteristics of the two images (spatial, spectral, temporal). We now
present the results of this method for real MERIS images (level 1b and 2) in a coastal area. The robustness of the method is

The study of the fish population of the Bay of Aiguillon salt marsh (France) and the Mont Saint-Michel Bay enabled us to
demonstrate the existence in this singular system of a structuration in colonizing guilds. Some species colonize the marsh
exclusively during their first year or first years (salt marsh colonizing year's youths and juveniles) Other species reside in the
marsh, like the gobies Pomatoschistus spp. and spend their entire biological cycle around the marsh (salt marsh colonizing
resident species). Another category of species goes about the marsh in an opportunist way, using it as a privileged feeding area
during their early stages or when adults (salt marsh colonizing opportunist species). The activities linked to the conservation of

Automatic dynamic mask extraction for PIV images containing an unsteady interface, bubbles, and a
moving structure
Provedor de dados: 5
Autores: Dussol, David; Druault, Philippe; Mallat, Bachar; Delacroix, Sylvain; Germain, Gregory.
When performing Particle Image Velocimetry (PIV) measurements in complex fluid flows with moving interfaces and a
two-phase flow, it is necessary to develop a mask to remove non-physical measurements. This is the case when studying, for
example, the complex bubble sweep-down phenomenon observed in oceanographic research vessels. Indeed, in such a
configuration, the presence of an unsteady free surface, of a solid–liquid interface and of bubbles in the PIV frame, leads to
generate numerous laser reflections and therefore spurious velocity vectors. In this note, an image masking process is developed to
successively identify the boundaries of the ship and the free surface interface. As the presence of the solid hull surface induces
laser reflections, the hull...

This study analyses the larval recruitment and biology in Crassostrea Gigas, in the Arcachon Bay. Three types of observations
were conducted: - a study of the reproduction anomalies in C. gigas between 1976 and 1981. - observations of the particulate
nutrition of the veligeres. - ecotoxicologic experiments (organostannic action on oyster reproduction, mostly). The reproduction
anomalies in C. gigas could not be attributed to either the genitors' quality or the water quality in the Arcachon Bay, but to a
perturbation of the veligeres' trophic regime; the hypothesis of an alteration of the nanoplancton in the Bay, during the summer
period, and linked to the action of the organotins is highly considered. The assumption of responsibility of the particulate...

Mollusc death assemblages were recovered in 98 subtidal sampling stations on the seafloor of the shallow Pertuis Charentais Sea
(Atlantic coast of France). Taxonomic composition and spatial distribution of death assemblages were investigated, as well as
their response to sediment grain size (field data), bottom shear stress (coupled tide and wave hydrodynamic modelling), and
sediment budget (bathymetric difference map) Results showed that molluscs are likely to be reliable paleoenvironmental
indicators since death assemblages were able to acquire ecological changes within years (decadal-scale taphonomic inertia), and
live-dead agreement inferred from existing data on living benthic communities was high, except close to river mouths and
intertidal mudflats...

On the mechanisms behind decadal heat content changes in the eastern subpolar gyre
Provedor de dados: 5
Autores: Desbruyeres, Damien; Mercier, Herle; Thierry, Virginie.
Historical and modern hydrographic data show substantial decadal variability in the heat content (HC) of the eastern subpolar
North Atlantic. Those changes are here investigated in an eddy-permitting simulation (ORCA025-G70) forced by reanalysis
products for the period 1965-2004. The observed and simulated decadal signal is characterized by a strong cooling in the 1960’s
and 1970’s, a period of minor changes in the 1980’s, and a strong warming in the 1990’s and 2000’s. A heat budget calculation is
performed within a box bounded by the Greenland-Scotland sills and the Cape Farewell (Greenland)-Portugal A25-Ovide section.
The decadal variability of HC is mainly governed by the integrated effect of anomalous oceanic heat transport across A25-Ovide...

The Congo deep-sea fan is one of the largest fans in the world still affected by presently active turbidity currents. The present
activity of deep-sea sedimentary processes is linked to the existence of a direct connection between the Congo River estuary and
the Congo canyon head that allows relatively continuous sediment feeding of the deep-sea environment, in spite of a wide
continental shelf (150 km). Because of this important activity in terms of sedimentary processes, the deep-sea environment of the
Congo-Angola margin presents major interests concerning physical, chemical and biological studies near the seafloor. The main
aim of this paper is to present the initial geological context of the BioZaire Program, showing a synthesis of the major results...

A spatially explicit coupled hydrodynamic-biogeochemical model was developed to study a coastal ecosystem under the
combined effects of mussel aquaculture, nutrient loading and climate change. The model was applied to St Peter's Bay (SPB),
Prince Edward Island, Eastern Canada. Approximately 40 % of the SPB area is dedicated to mussel (Mytilus edulis) longline
culture. Results indicate that the two main food sources for mussels, phytoplankton and organic detritus, are most depleted in the
central part of the embayment. Results also suggest that the system is near its ultimate capacity, a state where the energy cycle is
restricted to nitrogen-phytoplankton-detritus-mussels with few resources left to be transferred to higher trophic levels. Annually,

Autores: Auffret, Mathieu; Diouris, M; Herry, A.
Bivalve molluscs possess several types of hemolymph cells (hemocytes), involved in internal defense and other physiological
functions. Studies in pathological and experimental conditions have shown their micro- and macrophagic ability. However, the
mechanisms of intracellular digestion are incompletely known in these organisms. The lysosomal apparatus of hemocytes was
therefore investigated in several species by hydrolase localization with the electron microscope. The cytoplasmic granules of
granulocytes displayed a strong acid beta -glycerophosphatase activity. Previous observations had shown that these granules may
contain phagocytized material. This indicates that intracellular digestion is achieved in these organelles. Acid beta

The growing development of thermonuclear electric plants on coastal areas drove the I.S.T.P.M. to carry out a number of impact
studies. Previous works on the impact of the transit in the condensers on the phytoplankton have been published by the Pollution
Biological Effects laboratory (Maggi el al., 1979 and 1980; Lassus and Maggi, 1980). Our results on the chlorophycea Dunaliella
terliolecla demonstrated that thermic elevations from low temperatures stimulated its cellular development. Therefore, it seemed
interesting to measure the effects of these thermic shocks on dinophyceae (or dinoflagellates), components, with diatoms, of the
coastal phytoplankton, and main agents of the summer phenomena known as "red waters".

Numerical simulation of the wake of marine current turbines with a particle method
Provedor de dados: 5
Autores: Pinon, Gregory; Mycek, Paul; Germain, Gregory; Rivoalen, Elie.
This paper presents numerical computations of three bladed horizontal axis marine current turbines in a uniform free upstream
current. The unsteady evolution of the turbine wake is taken into account by some three-dimensional software, developed to assess
the disturbances generated in the sea. An unsteady Lagrangian method is considered for these computations using "Vortex
Method": a velocity-vorticity numerical implementation of the Navier-Stokes equations. The vortex flow is discretised with
particles carrying vorticity, which are advected in a Lagrangian frame. The present paper aims at presenting results on both power
and thrust coefficient (C-p and C-T) predictions and wake characterisation, up to ten diameters downstream of the turbine.
Moreover, two...

Genetic diversity of the European oyster (Ostrea edulis L.) in Nova Scotia: Comparison with other
parts of Canada, Maine and Europe and implications for broodstock management
Provedor de dados: 5
Autores: Vercaemer, Bénédikte; Spence, Koren R.; Herbinger, Christophe; Lapegue, Sylvie; Kenchington, Ellen L.
The European oyster (Ostrea edulis) was introduced to the Nova Scotia aquaculture industry 30 years ago using stocks imported
from naturalized populations in Maine whose ancestors originated in the Netherlands. This study used 5 microsatellites to assess
the level of genetic diversity in several hatchery stocks and naturalized populations from Nova Scotia, New Brunswick, British
Columbia and Maine. Some genetic erosion was shown to have occurred in the Maritimes populations, with the largest loss of
alleles being experienced by the hatchery stocks. In spite of this loss, genetic diversity and heterozygosity in the Maritimes
populations are still relatively high. Relationships within and between the populations and the existence of kin groups within the...

Few antifungal protective cultures adapted to fermented dairy products are commercially available because of the numerous
constraints linked to their market implementation. Consumer’s demand for naturally preserved food products is growing and the
utilization of lactic acid bacteria is a promising way to achieve this goal. In this study, using a 25-1 factorial fractional design, we
first evaluated the effects of fermentation time, of initial sucrose concentration and of the initial contamination amount of a
spoilage yeast, on antifungal activities of single and mixed cultures of Lactobacillus rhamnosus K.C8.3.1I and Lactobacillus

Autores: Prevedelli, D; Simonini, R.
The life cycle of five species of polychaetes living in the Venice lagoon is analysed with the aim of finding out if some traits can
be interpreted as an adaptation to brackish environments. The studied species are characterized by different sizes and reproductive
strategies. Marphysa sanguinea is a large-sized, annual iteroparous species belonging to the Eunicidae family that reproduces
without epitokal modification. Perinereis cultrifera and P. rullieri are large-sized semelparous species belonging to the Nereididae
family: the first reproduce with epitokal metamorphosis, the second do not. Ophryotrocha labronica and Dinophilus gyrociliatus
are small iteroparous species with semi-continuous reproduction belonging to the Dorvilleidae and Dinophilidae...

Lee wave generation rates in the deep ocean

Autores: Wright, Corwin J.; Scott, Robert; Ailliot, Pierre; Furnival, Darran.
Using the world's largest data set of in situ ocean current measurements, combined with a high-resolution topography roughness
data set, we use a model-assisted hierarchical clustering methodology to estimate the global lee wave generation rate at the ocean
floor. Our analysis suggests that internal wave generation contributes 0.750.19 TW (2 standard deviation) to the oceanic energy
budget but with a strong dependence on the Brunt-Vaisala (buoyancy) frequency climatology used. This estimate is higher than
previous calculations and suggests that internal wave generation may be a much more significant contributor to the global oceanic
mechanical energy budget than had previously been assumed. Our results imply that lee wave generation and propagation may

Autores: Siano, Raffaele; Alves-de-souza, C.; Foulon, E.; Bendif, El Mahdi; Simon, N.; Guillou, L.; Not, F.
Sequences affiliated to Syndiniales (Marine alveolate, MALV) regularly dominate 18S rDNA genetic libraries of nearly all marine
ecosystems investigated so far. Among them, Amoebophryidae (MALV group II) is composed of numerous and genetically
distant environmental sequences, where Amoebophrya is the only known and formally described genus. Amoebophrya species
include virulent pathogens for a wide range of dinoflagellate species. Beside their regular occurrence in marine ecosystems, their
quantitative distribution and the environmental factors triggering host infection have barely been studied in open oligotrophic
waters. In order to understand the functional role of these parasites in natural environments, we studied the distribution and

Autores: Pommepuy, Monique; Le Saux, Jean-claude; Hervio Heath, Dominique; Le Guyader, Soizick.
Infectious diseases linked to the consumption of raw shellfish like oysters, mussels, cockles and clams, have long been identified.
Bacterial diseases such as cholera and typhoid fever were the first to be suspected of being linked to consumption of contaminated
shellfish (Butt et al., 2004). During the past century, various strategies have been established in shellfish growing areas throughout
the world to assure the sanitary quality of shellfish. More recently, despite sanitary surveys, Vibrio parahaemolyticus, Vibrio
vulnificus and enteric viruses - especially Hepatitis A virus (HAV) and norovirus (NoV) – were found to be associated in
outbreaks of human illness.

Seasonal heat content in the eastern Tropical Atlantic
Provedor de dados: 5
Autores: Verstraete, J M.
The supper ocean heat content and seasonal sea level changes in the eastern Tropical Atlantic do not depend only upon the vertical
displacements of the shallow tropical thermocline and changes in the temperature and thickness of the tropical surface waters.
These seasonal changes also depend heavily upon the changes in thickness of the South Atlantic central waters, advected to the
east into the Gulf of Guinea by the three equatorial counter-currents, and polewards from the Equator along the African shelf edge
by the coastal counter-currents. The heat content of the tropical surface waters and the South Atlantic central waters are compared:
heat gain and loss between these two water masses seem to be in balance.

Novel mechanical characterization method for deep sea buoyancy material under hydrostatic

Provedor de dados: 5
Autores: Le Gall, Maelenn; Choqueuse, Dominique; Le Gac, Pierre-yves; Davies, Peter; Perreux, Dominique.
Syntactic foams, used in submersibles and in pipelines for deep sea oil wells, must be resistant to the severe conditions of the deep
sea environment. As these foams will be in service for at least 20 years, their qualification testing is crucial. However, their
mechanical characterization under real conditions of use is a challenge. In deep sea, the main loading is hydrostatic compression,
however there is no standard procedure for testing material under pure hydrostatic pressure. The aim of this paper is to present a
new characterization technique based on buoyancy loss measurement under hydrostatic pressure. To validate the method, two
different syntactic foams (one brittle and one ductile) have been tested. Their behaviours under hydrostatic pressure...

The temporary bad bacteriological results in some shellfish harvesting areas in Brittany (France) lead us to recommand the use of
insubmersible aerate tanks in shellfish plant. The shellfish depuration kinetics are as good as those noted in purification plants
using chemically or physically purificated water. The generalisation of this technic to a regional scale corroborates its efficiency
and allows us to fix good practice rules. The observance of these rules must lead shellfish-grower to sell, permanently,
bacteriologically proper products.

Since about twenty years, Ifremer have carried out fishery surveys along the French coasts. A dynamic indicator-based approach
to the assessment of multi-stock fisheries has been applied to these data series. Reference points for non-commercial populations
and community indicators are seldom available, but reference directions are well established: it is known whether fishing will
increase or decrease the indicator, hence the direction that should be avoided. A set of simple indicators of fishing impacts on fish
populations and communities were estimated from time-series data provided by scientific surveys (population abundance and
average length, community total biomass and number, average length and weight, and size spectrum). Trends in these indicators...

Laboratory experiments performed in a recirculating flume were designed to quantify the bioturbation influence of the mud snail
Hydrobia ulvae, one of the most abundant deposit feeders on European intertidal mudflats. Variations in sediment moisture
content that occur between bedforms in shore-normal, ridge and runnel systems of intertidal mudflats were added to the model
definition. Sediment erosion thresholds, erosion rates and the microalgal pigment composition of resuspended material were

The weighted curvature approximation in scattering from sea surfaces

Autores: Guerin, Charles-antoine; Soriano, Gabriel; Chapron, Bertrand.
A family of unified models in scattering from rough surfaces is based on local corrections of the tangent plane approximation
through higher-order derivatives of the surface. We revisit these methods in a common framework when the correction is limited
to the curvature, that is essentially the second-order derivative. The resulting expression is formally identical to the weighted
curvature approximation, with several admissible kernels, however. For sea surfaces under the Gaussian assumption, we show that
the weighted curvature approximation reduces to a universal and simple expression for the off-specular normalized radar
cross-section ( NRCS), regardless of the chosen kernel. The formula involves merely the sum of the NRCS in the classical

Summer seed mortality (SSM) has occurred yearly in Tomales Bay, California since 1993. SSM has resulted in up to 90%
cumulative losses, and has been associated with extreme temperature, phytoplankton blooms, and an oyster herpesvirus. In this
study, three stocks of Pacific oysters were planted at three sites in California (Inner Tomales Bay, Outer Tomales Bay, and
Bodega Harbor) in October of 2000 (Fall) and April of 2001 (Spring) and monitored for mortality, growth, and health status. In
April of 2001, a similar study was conducted in Totten Inlet, WA state using cohorts of oysters planted in California; animals
were monitored for mortality and growth. Temperature data were collected at all sites; phytoplankton abundance data were
collected at the...

Avec l'accroissement démographique, le volume des eaux résiduaires déversées quotidiennement dans l'environnement marin a
atteint des niveaux considérables. Le littoral marin reçoit, en effet, les eaux usées provenant des émissaires des agglomérations
littorales, les eaux fluviales et d'estuaires utilisées parfois pour les rejets domestiques, et les eaux de ruissellement terrestre
pouvant entraîner détritus et déchets animaux. D'une manière générale, ces eaux résiduaires renferment des matières organiques en
grande quantité, des micropolluants (détergents, hydrocarbures) mais surtout des micro-organismes apportés le plus souvent par
les matières fécales. En dépit de leur traitement au niveau des stations d'épuration, leur concentration en bactéries reste...

Evolution des concepts d'exploitation miniere en mer
Provedor de dados: 5
Autores: Bivaud, J.
At present, offshore placers are generally exploited by means of traditional dredging equipment. This technique, called the
"vertical method," consists of working the seabed directly from the surface support vessel through a rigid upflow pipe equipped,
when necessary, with a sediment preloosening system. In contrast with the vertical method, this approach is based on the principle
of working along the seabed with transfer of spoil up to the surface after extraction. We therefore call this the "horizontal
method." Although it varies according to sites, in most cases this method comprises the design of a vehicle, self-propelled to some
degree, which moves along the seafloor, carries and operates the appropriate mining tools and includes a system to transfer...

Noroviruses (NoV) are major agents of acute gastroenteritis in humans and the primary pathogens of shellfish-related outbreaks.
Previous studies showed that some human strains bind to oyster tissues through carbohydrate ligands that are similar to their
human receptors. Thus, based on presentation of shared norovirus carbohydrate ligands, oysters could selectively concentrate
animal strains with increased ability to overcome species barriers. In comparison with human GI and GII strains, bovine GIII NoV
strains, although frequently detected in bovine feces and waters of two estuaries of Brittany, were seldom detected in oysters
grown in these estuaries. Characterization of the carbohydrate ligand from a new GIII strain indicated recognition of the...

The REPAMO network (network ofmollusc pathology), created in 1986, ensures the survey of shellfish health status along French
coasts according? to European Directives 91/67/EEC and 95/70/EEC. The aims of the network are 1 - to prevent the introduction
and spread of exotic pathogens, 2-to study the means to decrease the impact of pathogens already present and to survey their
evolution. In 2003, the REPAMO network focused on the survey oflisted diseases (bonamiosis and marteiliosis) in two areas
under agreement process (Banc de Granville and zone X) and on the study of abnormal morlalities. Number of reported abnormal
morlalities has increased in 2003. This rise can be partly explained by the recent network restructuring, but also by the summer

Autores: Renault, Tristan; Lipart, Cecile; Arzul, Isabelle.
Sporadic high mortalities were reported in June 1997 among hatchery-reared larval Manila clam Ruditapes philippinarum in a
French commercial hatchery. Cellular abnormalities were observed in semi-thin sections in affected animals. Transmission
electron microscopy revealed the presence of herpes-like virus particles in larvae. This is the first description of a herpes-like virus
infection in larval R. philippinarum, a non-ostreid bivalve species. Virus particles were similar to other herpes-like viruses
described from different oyster species with respect to ultrastructure and morphogenesis. Electron microscopic examination also
demonstrated cells with condensed chromatin and extensive perinuclear fragmentation of chromatin. Like viruses infecting
oysters,...

Modeling flocculation processes : intercomparison of a size class-based model and a
distribution-based model
Provedor de dados: 5
Autores: Maerz, Joeran; Verney, Romaric; Wirtz, Kai; Feudel, Ulrike.
Modeling suspended particulate matter (SPM) dynamics is essential to calculate sediment transport budgets and to provide
relevant knowledge for the understanding of biogeochemical cycles in coastal waters. Natural flocs are characterized by their size,
shape, structure and density that determine their settling velocity and therefore their vertical as well as horizontal transport. During
transport, several processes, in particular aggregation and fragmentation, alter these particle properties. In the present study, we
compare two different 0D modeling approaches for flocculation processes, a size class-based (SCB) model and a
distribution-based (DB) model that follows the first moment of the particle distribution function. The study leads to an improved...

Provedor de dados: 5
Autores: Dang, C.; Gonzalez, P.; Mesmer-dudons, N.; Bonami, J-r; Caill-milly, Nathalie; De Montaudouin, X.
Recently, Manila clam, Ruditapes philippinarum, populations have suffered mortalities in Arcachon Bay (SW France). Mortality
was associated with extensive lesions of the posterior adductor muscle, which become progressively brown and calcified.
Ultrastructural observations by transmission electron microscopy revealed tissue degradation with necrotized muscle fibres and
granulocytomas. Unenveloped virus-like particles (VLPs) were detected in muscle, granulocytic, epithelial and rectal cells. VLPs
were abundant in the extracellular space, in the cytoplasm (free or enclosed in vesicles) and in the nucleoplasm of granulocytes.
Nuclei and mitochondria of granulocytes displayed changes which suggested reactive oxygen species production and apoptosis

In the present work, seven genes encoding Na+,K+-ATPase (NKA) β-subunits in the teleost Solea senegalensis are described for
the first time. Sequence analysis of the predicted polypeptides revealed a high degree of conservation with those of other
vertebrate species and maintenance of important motifs involved in structure and function. Phylogenetic analysis clustered the
seven genes into four main clades: β1 (atp1b1a and atp1b1b), β2 (atp1b2a and atp1b2b), β3 (atp1b3a and atp1b3b) and β4
(atp1b4). In juveniles, all paralogous transcripts were detected in the nine tissues examined albeit with different expression

Detection of mesoscale thermal fronts from 4km data using smoothing techniques: Gradient-based
fronts classification and basin scale application
Provedor de dados: 5
Autores: Roa Pascuali, Liliana; Demarcq, Herve; Nieblas, Anne-elise.
In order to optimize frontal detection in sea surface temperature fields at 4 km resolution, a combined statistical and expert-based
approach is applied to test different spatial smoothing of the data prior to the detection process. Fronts are usually detected at 1 km
resolution using the histogram-based, single image edge detection (SIED) algorithm developed by Cayula and Cornillon in 1992,
with a standard preliminary smoothing using a median filter and a 3 × 3 pixel kernel. Here, detections are performed in three study

Selective breeding of shrimp for viral resistance is established for species like L. vannamei and L. stylirostris. However, selection
for bacterial infection resistance is not documented. In New Caledonia, "Syndrome 93" is a vibriosis that affects cultured shrimps
during the cool season with survival from 15 to 30%. Current practises for breeders rearing at low densities do not improve the
resistance of the offsprings mainly because selection pressures for "Syndrome 93" are low. Even after the fifth generation,
survival improvement is not significant.

A study was conducted to investigate the involvement of bacteria in oyster mortalities during summer. Moribund and apparently
healthy oysters were sampled during mortality events along the French coast and in rearing facilities, usually when temperature
reached 19 degrees C or higher, and oysters were in the gonadal maturation phase. Hemolymph samples were aseptically
withdrawn and submitted to bacteriological analysis. In healthy oysters, bacteria colonized hernolymph at low concentrations
depending on the location. In most moribund oysters, bacteria were present in hemolymph and other tissues. These bacterial
populations were more often diverse in oysters originating from the open sea than from facilities where animals were generally

Recent advances in understanding the Arctic climate system state and change from a sea ice
perspective: a review
Provedor de dados: 5
Autores: Doscher, R.; Vihma, Timo; Maksimovich, Elena.
Sea ice is the central component and most sensitive indicator of the Arctic climate system. Both the depletion and areal decline of
the Arctic sea ice cover, observed since the 1970s, have accelerated since the millennium. While the relationship of global
warming to sea ice reduction is evident and underpinned statistically, it is the connecting mechanisms that are explored in detail in
this review. Sea ice erodes both from the top and the bottom. Atmospheric, oceanic and sea ice processes interact in non-linear
ways on various scales. Feedback mechanisms lead to an Arctic amplification of the global warming system: the amplification is
both supported by the ice depletion and, at the same time, accelerates ice reduction. Knowledge of the mechanisms of sea...

Autores: Bellon, Gilles; Sobel, Adam H.; Vialard, Jerome.
A simple coupled model is used in a zonally symmetric aquaplanet configuration to investigate the effect of ocean-atmosphere
coupling on the Asian monsoon intraseasonal oscillation. The model consists of a linear atmospheric model of intermediate
complexity based on quasi-equilibrium theory coupled to a simple, linear model of the upper ocean. This model has one unstable
eigenmode with a period in the 30-60-day range and a structure similar to the observed northward-propagating intraseasonal
oscillation in the Bay of Bengal/west Pacific sector. The ocean-atmosphere coupling is shown to have little impact on either the
growth rate or latitudinal structure of the atmospheric oscillation, but it reduces the oscillation's period by a quarter. At latitudes...

Application of DNA parentage assignment for commercial selection in aquaculture is still rare. An experiment was performed to
quantify and to minimize maternal effects on growth in rainbow trout. Six hundred families were reared until 198 day post
fertilization (dpf) according to two different procedures. In the first procedure (NORM), all families were pooled at eyed stage. In
the second procedure (MIN), where maternal effects due to differences in egg size were expected to be minimal, the spawns were
divided into sub-groups with similar mean egg weight at eyed stage. These sub-groups were then pooled when they achieved the
same mean body length (147 dpf). Genetic parameters were estimated for body weight, body length and condition factor at 198
dpf, with...

Variations in demographic parameters between intertidal populations of Nereis virens and Nephtys caeca were studied. These
polychaetes are major component of the Macoma balthica community in the Lower St. Lawrence estuary (Quebec, Canada). We
compared spatial distribution between differently oriented shores in a small geographic area. Our results revealed an
interpopulation variability that appears to be dependent on hydrodynamical processes, edaphic parameters and biological
interactions. In north and northeast oriented flats, the higher densities of young individuals of Nereis virens are found in the higher
tidal levels where we observed larval recruitment and the highest organic matter contents. On the other hand, the lower densities
of adult worms are...

The multi-use in wind farm projects: more conflicts or a win-win opportunity?
Provedor de dados: 5
Autores: Lacroix, Denis; Pioch, Sylvain.
The pressures on the use of the seashore are steadily rising, not only in developed countries but worldwide. Anthropogenic
activity has long impacted the marine continental shelf down to a depth of approximately -200 m. New activities are now affecting
this coastal space such as renewable energies, recreational uses and aquaculture in addition to the traditional ones of navigation or
fishing. This evolution raises new sources of conflict amongst users which can require state involvement in order to manage the
different stakeholders and pressure groups. However, the coastal space still offers a large potential for development for two
reasons. Firstly, the physical three dimensional potential of this space enables the whole water column to be used,...

Biogeography and Potential Exchanges Among the Atlantic Equatorial Belt Cold-Seep Faunas
Provedor de dados: 5
Autores: Olu, Karine; Cordes, Erik E.; Fisher, Charles R.; Brooks, James M.; Sibuet, Myriam; Desbruyeres, Daniel.
Like hydrothermal vents along oceanic ridges, cold seeps are patchy and isolated ecosystems along continental margins, extending
from bathyal to abyssal depths. The Atlantic Equatorial Belt (AEB), from the Gulf of Mexico to the Gulf of Guinea, was one
focus of the Census of Marine Life ChEss (Chemosynthetic Ecosystems) program to study biogeography of seep and vent fauna.
We present a review and analysis of collections from five seep regions along the AEB: the Gulf of Mexico where extensive faunal
sampling has been conducted from 400 to 3300m, the Barbados accretionary prism, the Blake ridge diapir, and in the Eastern
Atlantic from the Congo and Gabon margins and the recently explored Nigeria margin. Of the 72 taxa identified at 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.

Etat de la motorisation de la flottille de pêche côtière en Martinique
Provedor de dados: 5
Autores: Bellemare, M; De Miras, C; Soumbo, C.
Ces premiers résultats inspirent trois principales remarques: 1 - La puissance moyenne des moteurs hors-bord varie très
sensiblement de la côte atlantique A la côte caraïbe. Si la puissance moyenne en Martinique est de prés de 40 cv par moteur, les
pêcheurs de la côte caraïbe utilisent une puissance moyenne unitaire de 30 cv alors que la motorisation sur la côte atlantique se
situe en termes de puissance moyenne autour de 46 cv. Cette différence s'explique peut-être par le type de pêche dominant dans
chacune de ces zones. En toute hypothèse, les résultats de l'activité des marins pêcheurs de la côte atlantique permettent-t-ils de
couvrir et justifient-t-ils donc le surcoût engendré au niveau de "l'investissement-moteur" (de 1.3 à 1.5 fois supérieur au coat...

Operational modelling of nutrients and phytoplancton in the bay of biscay and english channel
Provedor de dados: 5
Autores: Menesguen, Alain; Dussauze, Morgan; Lecornu, Fabrice; Dumas, Franck; Thouvenin, Benedicte.
Nitrate loadings to the French coastal waters of the Bay of Biscay and the English Channel have increased from 5 to 10 times
during the four last decades, due to runoff on intensively fertilized agricultural watersheds. Eutrophication of this coastal zone is
now a recurrent problem, with wellknown direct impacts (Ulva “green tides” on beaches, excessive phytoplanktonic blooms
responsible for “coloured waters” and bottom hypoxia events offshore), but also indirect enhancement of the toxicity of some
phytoplankton species, caused for instance by increased N:Si ratio in the coastal sea. In order to better guide the decision makers
about nutrient loading reduction, Ifremer uses the so-called ECO-MARS3D biogeochemicalhydrodynamical model to simulate the

The influence of horizontal and vertical displacements on phytoplankton assemblages in tropical
upwelling systems
Provedor de dados: 5
Autores: Smith, W O; Barber, R T.
The mechanisms by which pelagic communities are regulated in physically dynamic environments have only recently begun to be
elucidated. Phytoplankton assemblages in upwelling regions are only influenced by chemical and biological interactions, but are
dramatically impacted by a three-dimensional advective regime. The "success" of a phytoplankton assemblage, as defined by its
biomass, growth and persistence through time, is often primarily controlled by the combined effects of particle sinking and its
interaction with the physical field. It is shown that the pattern of circulation deduced from surface drogues is usually not coherent
throughout the euphotic zone. Vertical movement of an upwelled water parcel has the potential for rapidly changing the light...

Autores: Colorni, A.
A condition in Sparus aurata larvae termed "distended gut syndrome" (DGS) has become a major problem in the past three
seasons. Unable to digest rotifers and brine shrimp nauplii, the larvae develop a swollen abdomen, exhibit a disoriented spinning
motion and are swept passively with the current. Bacterial or viral infections were suspected. Chloramphenicol-supplemented
larval food did not affect the prevalence of DGS. Virus-like particles 80 nm in diameter were observed in necrotic cytoplasm of
midgut wall cells.

In aquaculture, particularly in bivalve hatcheries, the biochemical composition of algal diets has a strong influence on larval and
post-larval development. Biochemical composition is known to be related to culture conditions, among which light represents a
major source of variation. The effects of blue light on biochemical composition and photosynthetic rate of Isochrysis sp. (T-iso)

Propagation of narrow-band-high-frequency clicks: Measured and modeled transmission loss of

Provedor de dados: 5
Autores: De Ruiter, Stacy; Hansen, Michael; Koopman, Heather N.; Westgate, Andrew J.; Tyack, Peter L.; Madsen, Peter T.
Estimating the range at which harbor porpoises can detect prey items and environmental objects is integral to understanding their
biosonar. Understanding the ranges at which they can use echolocation to detect and avoid obstacles is particularly important for
strategies to reduce bycatch. Transmission loss (TL) during acoustic propagation is an important determinant of those detection
ranges, and it also influences animal detection functions used in passive acoustic monitoring. However, common assumptions
regarding TL have rarely been tested. Here, TL of synthetic porpoise clicks was measured in porpoise habitats in Canada and
Denmark, and field data were compared with spherical spreading law and ray-trace (Bellhop) model predictions. Both models

liquid smoke atomisation, and two electrostatic smoking processes, also involving smouldering or friction. The effects of several
parameters, such as smoking time, smokehouse temperature, electrode voltage, and fish fillet temperature before smoking were
assessed for each process. The results indicate that the content of phenolic compounds are strongly affected by the process

Germanium (Ge) and Silicon (Si) exhibit similar geochemical behaviour in marine environments but are variably enriched in
seafloor hydrothermal fluids relative to seawater. In this study, Ge isotope and Ge/Si ratio systematics were investigated in low
temperature hydrothermal vents from Loihi Seamount (Pacific Ocean, 18°54’N, 155°15’W) and results were compared to
high-temperature vents from the East Pacific Rise (EPR) at 9°50’N. Loihi offers the opportunity to understand contrasting Ge and
Si behaviour in low temperature seafloor hydrothermal systems characterized by abundant Fe oxyhydroxide deposition at the
seafloor. The results show that both Ge/Si and δ74/70Ge in hydrothermal fluids are fractionated relative to the basaltic host rocks.

For many trace elements, continental margins are the location of intense exchange processes between sediment and seawater,
which control their distribution in the water column, but have yet to be fully understood. In this study, we have investigated the
impact of fluid seepage at cold seeps on the marine cycle of neodymium. We determined dissolved and total dissolvable (TD)
concentrations for REE and well-established tracers of fluid seepage (CH4, TDFe, TDMn), and Nd isotopic compositions in
seawater samples collected above cold seeps and a reference site (i.e. away from any fluid venting area) from the Niger Delta

et Mesquer ont été transformés en claires pour l'affinage des huîtres. Des paludiers ont recherché un complément à leur activité
salicole dans l'élevage de la palourde. Par ailleurs, plusieurs entreprises ont créé un élevage de palourdes dans les marais, et sur
l'estran. Les marais sont des milieux fragiles très sensibles aux diverses pollutions, notamment bactériennes, qui ont été mises en
évidence par la DDASS, et par différentes études. Elles sont essentiellement d'origines urbaine et domestique, et proviennent des
rejets ponctuels et permanents d'eaux usées dans les réseaux pluviaux, les fossés et les ruisseaux, qui...

Evolution de certaines pêcheries de l'Atlantique nord-ouest 1960-1972
Provedor de dados: 5
Autores: Morice, Jean; Durand, René.
Le bref exposé qui suit a pour but de décrire l'évolution comparée des pêcheries françaises (morue), espagnoles (morue),
allemandes (morue, sébaste, hareng) et terre-neuviennes (morue, sébaste, hareng). La Grande Pêche française, dans l'Atlantique
nord-ouest, n'a jamais salé ou congelé autre chose que de la morue. Il y a relativement peu de temps que des navires congélateurs
remplacent peu à peu les anciennes unités de la pêche salée. Pour fixer les idées, en 1972, 12 navires classiques et seulement 15
chalutiers congélateurs ou mixtes étaient engagés dans la pêche à la morue ; il est vrai qu'en 1973 le Comité Interprofessionnel de
la Grande Pêche prévoyait que le nombre des classiques serait réduit à 7 navires tandis que celui des mixtes et des...

Provedor de dados: 5
Autores: Madec, V.
Studies of the functioning of intertidal ecosystems are widely based on analyses of the biological rhythms due to sea movements,
estimating an average rate for emersion at all points of the foreshore. This estimate supplies an explicative parameter related to
distribution of animal and vegetable species. We present a spatial model for estimation of emersion rates based on the processing
of geocoded data within a geographical information system (GIS).

Sea-temperature anomalies and population dynamics variations : effects on growth and density of
three bivalves
Provedor de dados: 5
Autores: Menesguen, Alain; Dreves, Luc.
The demographic structure of stable populations is usually modelled by a simple exponential decay mode. For 3 mollusc species,
this model has been improved by taking inlo account monthly sea-temperature anomalies calculated on a 20 yr daily temperature
chronicle. For the 3 species examined, Tapes rhomboïdes, Glycymeris glycymeris and Spisula ovalis, from the southern part of the
Western English Channel, only temperature anomalies during the 2 mo following the major spawning period were positively
eorrelated with density anomalies, probably in eonneetion with larval stage sensitivity. Comparison of temperature anomalies and
mean annual growth va riability suggests an apparent positive effeet of temperature during autumn or winter months, significant

Evolution de la flore bactérienne de l'estuaire de l'Elorn

Les estuaires, zones de mélange d'eaux douces et d'eaux marines, ont, de tout temps, été l'objet de multiples activités, tant
industrielles que maricoles (élevage de coquillages, pêche,... ) L'agglomération autour d'une zone relativement fermée, d'une
population humaine et de ses activités, a des conséquences obligatoires sur la faune et sur la flore de l'estuaire et, en particulier,
sur les populations bactériennes. En effet, le rejet d'eaux usées, fortement chargées en bactéries contaminantes et en matière
organique, dans une zone où le renouvellement des eaux se fait de façon relativement lente, favorise la survie des bactéries
étrangères au milieu. De même, les apports en éléments nutritifs modifient la flore marine autochtone. Enfin, la présence de...

Exploring durability of interfaces in flax fibre/epoxy micro-composites
Provedor de dados: 5
Autores: Le Duigou, Antoine; Davies, Peter; Baley, Christophe.
The influence of wet aging on the behaviour of flax/epoxy micro-composites composed of single flax fibres embedded in epoxy
micro-droplets has been studied. Interfacial shear strength has been examined by debonding the micro-droplets. The apparent
interfacial shear strength decreases with immersion time in water, dropping rapidly during the first 15 min of immersion then
stabilizing. Drying samples after short immersion periods allows recovery of properties, indicating a plasticization mechanism.
For longer immersion times irreversible degradation is observed. Scanning electron microscopy reveals fibre surface peeling,
indicating that an internal interface within the fibre is weaker than the fibre/matrix interface after aging. A simple descriptive

This work aims to describe fishing activity in Guadeloupe through a typology. The samply unit y is the landing represented by a
profile of specific composition. Using multivariate analysis methods allows to synthesize this fishing multi specises and multi
fishing tackles. Principal Component Analysis and classification regroup landings. Then, segmentation method separateses classes
by species composition. Typology is obtained by association of classes and tackles. The contraist between landings of reef fishes
realized with traps and those which search for pelagics is clearly shown. Landings of queen conch and landings without fishes are

As part of the French CLIPPER project, an eddy permitting model of the Atlantic circulation has been run for 22 years. The
domain has open boundaries at Drake passage and at 30 degreesE, from Africa to Antarctica. The simulated mean circulation, as
well as the eddy activity, is satisfactory for a 1/3 degrees model resolution, and the meridional heat transport at 30 degreesS is
within the range estimated from observations. We use the "mixed" open boundary algorithm of Barnier et al. [1998], which has
both a radiation condition and a relaxation to climatology. The climatological boundary forcing strongly constrains the solution in
the whole domain. The model heat balance adjusts through the surface (heat flux retroaction term) more than the open
boundaries....

First results of an epidemiological study on oyster (Crassostrea gigas) mortality events in France
during summer 2008
Provedor de dados: 5
Autores: Miossec, Laurence; Allain, Gwenhael; Arzul, Isabelle; Francois, Cyrille; Garcia, Celine; Cameron, Angus.
Abnormal mortalities occurred in most oyster producing areas in France during the summer of 2008. The mortalities were
sudden and severe (up to 100%) and mainly affected 6 to 18 month old juveniles. Only Crassostrea gigas species was affected.
The cause of the mortality was unclear but OsHV-1 virus and bacteria belonging to Vibrionaceae family were frequently detected
in affected populations. An epidemiological study was commenced in autumn 2008 in order to identify factors associated with,
and the cause (or causes) of these mortalities. This paper presents the results of the first (descriptive) part of this investigation.
The objectives were to identify the affected population and to describe the pattern of mortalities in time and space. Mortality...

In the scope of the European program GENEPHYS, which aims to establish the relationship between the genetic base and the
physiological characters in relation to the growth in Crassostrea gigas, it has been demonstrated that the most explanatory factors
for the growth variability are assimilation performance and aneuploidy. A model linking the assimilation performances and the
digestive equipment has been set up and more than 70% of the variability can be explained by two digestive enzymes:
laminarinase and amylase. A number of laboratories have decided to focus on the latter.

Although Glycosyl-Inositol-Phospho-Ceramides (GIPCs) are the main sphingolipids of plant tissues, they remain poorly
characterized in term of structures. This lack of information, notably with regard to polar heads, currently hampers the
understanding of GIPC functions in biological systems. This situation prompted us to undertake a large scale-analysis of plant
GIPCs: 23 plant species chosen in various phylogenetic groups were surveyed for their total GIPC content. GIPCs were extracted
and their polar heads were characterized by negative ion MALDI and ESI mass spectrometry. Our data shed light on an
unexpected broad diversity of GIPC distributions within Plantae, and the occurrence of yet-unreported GIPC structures in green
and red algae. In monocots,...

The most recent geological history of the Black Sea, which covers the last 25 thousand years, is a subject of special attention
today. This interest is due mainly to the hypothesis we have launched about the early Holocene flood in the Black Sea. This
hypothesis was a real shock to the scientific community, among whom the Bulgarian geologists and archaeologists received it
with great hostility. The anathematization was accompanied by a fierce media campaign, as a result of which Prof. Robert Ballard,

Effects of short-term exposure to paralytic shellfish toxins on clearance rates and toxin uptake in five
species of New Zealand bivalve
Provedor de dados: 5
Autores: Contreras, Andrea; Marsden, Islay D.; Munro, Murray H. G.
Algal blooms produced by toxic dinoflagellates have increased worldwide, resulting in economic losses to aquaculture and
fisheries. Bivalve species differ in their ability to feed on toxin-producing dinoflagellates and this could result in differences in
toxin accumulation among species. In New Zealand, the effects of paralytic shellfish poisoning (PSP) toxins on the physiology of
bivalve molluscs are relatively unknown. We hypothesised that the feeding responses of five New Zealand bivalve species
exposed to PSP-toxic dinoflagellates would be species-specific, affecting their accumulation of toxins. Each species was exposed
to toxic and non-toxic species of Alexandrium spp. and clearance rate used as an index of sensitivity to PSP toxins. Clearance

biocomposite (20% and 30% fibres by weight) to be recycled. Mechanical properties were evaluated initially, and shown to be
similar to those of glass/PP and superior to hemp/PP and sisal/PP composites. Then after repeated injection cycles tensile
properties were shown to be conserved until the third cycle. Matrix degradation and fibre aspect ratio were followed using
molecular weight measurements, thermal and rheological analyses, image analysis of sections and SEM fractography. These

Crassostrea gigas mortality in France: the usual suspect, a herpes virus, may not be the killer in this
polymicrobial opportunistic disease
Provedor de dados: 5
Autores: Petton, Bruno; Bruto, Maxime; James, Adele; Labreuche, Yannick; Alunno-bruscia, Marianne; Le Roux, Frederique.
Successive disease outbreaks in oyster (Crassostrea gigas) beds in France have resulted in dramatic losses in production, and
subsequent decline in the oyster-farming industry. Deaths of juvenile oysters have been associated with the presence of a herpes
virus (OsHV-1 µvar) and bacterial populations of the genus Vibrio. Although the pathogenicity of OsHV-1 µvar, as well as
several strains of Vibrio has been demonstrated by experimental infections, our understanding of the complexity of infections
occurring in the natural environment remains limited. In the present study, we use specific-pathogen-free (SPF) oysters infected in
an estuarine environment to study the diversity and dynamics of cultured microbial populations during disease expression. We

Marine ecosystems are under increasing pressure from a diverse range of threats. Many national governments have responded to
these threats by establishing marine protected area (MPA) networks. One such approach for designing MPA networks is
systematic conservation planning, which is now considered the most effective system for designing protected area networks.
However, the main exception to this trend is Europe, where the designation of MPAs is still largely based on expert opinion,
despite growing awareness that these existing methods are not the most effective. Therefore, there is a need to demonstrate how
systematic conservation planning can be used to inform MPA design in European waters and show how this approach can fit

Quantitative evaluation of erosion/deposition events of surficial sediments is crucial to understand the processes and establish
sedimentary budgets in coastal areas The ALTUS system was designed for more than a decade, to meet this objective The
possibilities offered by this altimeter (short-term or several months measurements) are particularly fitted for validation of
sedimentary transport numerical models The recent integration of a large capacity memory card has allowed to optimize the
system Indeed it is well established that wave activity is one of the key parameters for the erosion and hence govern sediment
transport in intertidal/shallow water areas The ALTUS system in addition to bottom level variation recordings allows access to

Phosphorites and Paleoceanography
Provedor de dados: 5
Autores: Arthur, Ma; Jenkyns, H C.
Phosphorite genesis correlates in a general way with elevated sea level and warm climate and is therefore influenced by plate
tectonics and continental drift. Phosphorite genesis correlates more specifically with transgression -- a result of the interaction of
continental hypsometry, tectonic perturbation and eustatic effects -- whereby a small number of shallow slope and shelf sites are
available for phosphate fixation. Phosphorite genesis correlates with warm climate. Oceanic anoxic events (OAE's : episodes of
world-wide deposition and preservation of organic carbon), which also correlate with particularly high sea level stands, generally
do not coincide with major phosphorogenic episodes. In contrast to the assertions above, the permian Phosphoria...

Each summer, the IFREMER laboratory of Arcachon monitors, in the scope of an agreement with the Regional Conchological
Comity of Arcachon, the reproduction of Pacific oysters in the Arcachon Bay. This monitoring aims to provide oyster farmers
with information necessary to the spat collecting: - dates and amount of spawn, - larval development speed, - presence of the most
evolved stages in the habitat (close to fixation). Reproduction is monitored from mid-June to mid-September, with plankton being
sampled four times a week on different representative sites. Oyster larvae at different stages are counted. At the end of the
reproduction period (September-October), larval recruitment on collectors is estimated via the counting of the spats collected, with

Ostreid herpesvirus type 1 replication and host response in adult Pacific oysters, Crassostrea gigas

Autores: Segarra, Amelie; Baillon, Laury; Tourbiez, Delphine; Benabdelmouna, Abdellah; Faury, Nicole; Bourgougnon,
Nathalie; Renault, Tristan.
Since 2008, massive mortality outbreaks associated with OsHV-1 detection have been reported in Crassostrea gigas spat and
juveniles in several countries. Nevertheless, adult oysters do not demonstrate mortality in the field related to OsHV-1 detection
and were thus assumed to be more resistant to viral infection. Determining how virus and adult oyster interact is a major goal in
understanding why mortality events are not reported among adult Pacific oysters. Dual transcriptomics of virus-host interactions
were explored by real-time PCR in adult oysters after a virus injection. Thirty-nine viral genes and five host genes including
MyD88, IFI44, IkB2, IAP and Gly were measured at 0.5, 10, 26, 72 and 144 hours post infection (hpi). No viral RNA among the

Autores: Ahmad, F; Sultan, Sar.
The net rate of heat exchange at the water surface in the central Red Sea is calculated with reference to the equilibrium
temperature and the thermal exchange coefficient, both of which depend on meteorological variables. The monthly means of this
exchange agree well with the values computed on the basis of heat balance processes which include sensible, evaporative and
radiative heat fluxes.

A coupled movement and bioenergetics model to explore the spawning migration of anchovy in the
Bay of Biscay
Provedor de dados: 5
Autores: Politikos, Dimitrios; Huret, Martin; Petitgas, Pierre.
Adult anchovies in the Bay of Biscay perform north to south migration from late winter to early summer for spawning. However,
what triggers and drives the geographic shift of the population remains unclear and poorly understood. An individual-based fish
model has been implemented to explore the potential mechanisms that control anchovy's movement routes toward its spawning
habitats. To achieve this goal, two fish movement behaviors – gradient detection through restricted area search and kinesis –
simulated fish response to its dynamic environment. A bioenergetics model was used to represent individual growth and
reproduction along the fish trajectory. The environmental forcing (food, temperature) of the model was provided by a coupled...

A new approach to retrieve sea surface wind speed (SWS) in tropical cyclones (TCs) from the Advanced Microwave Scanning
Radiometer 2 (AMSR2) data is presented. Analysis of all six AMSR2 C- and X-band channel measurements over TCs is shown to
efficiently help to separate the rain contribution. Corrected measurements at 6.9 and 10.65 GHz are then used to retrieve the SWS.
Spatial and temporal collocation of AMSR2 and tropical rain measurement mission (TRMM) microwave instrument (TMI) data is
then further used to empirically relate TMI rain rate (RR) product to RR estimates from AMSR2 in hurricanes. SWS estimates are
validated with measurements from the stepped frequency microwave radiometer (SFMR). As further tested, more than 100 North

Investigating the performances of a bayesian biomass dynamic model with informative priors on
Atlantic bluefin tuna
Provedor de dados: 5
Autores: Simon, M; Fromentin, Jean-marc; Bonhommeau, Sylvain; Gaertner, Daniel; Etienne, Marie-pierre.
We examined the possibility of eliciting informative priors for the parameters of a biomass production model with emphasis on
the intrinsic population growth rate of Atlantic bluefin tuna (Thunnus thynnus). We reviewed the literature to propose probability
distribution functions for the vital rates and used a matrix population model structured by age (Leslie) to compute the population
growth rate. A generalized biomass production model is applied on two CPUE and catch datasets (1976-1996 and 1976-2006)
using informative priors. The population growth rate prior has a diffuse distribution and is very sensitive to young of the year
mortality rate. Thus, we compared the performances of this prior with a commonly used prior for tunas population growth rate.

This work deals with the fishing effects on the diversity dynamics of demersal fish communities, focusing on the biotic
interactions. Multispecies indices are used in order to characterize the demersal fish community dynamics of the Bay of Biscay
and of the Gulf of Lions. These are the diversity indices, the temporal variability of the total biomass and of the slope of the
number size spectra and the slope of the species-area curves (spatial segregation). The yearly bottom trawl surveys EVHOE,
CHALIST and MEDITS, carried out in these two areas since 1983 by IFREMER for the stocks assessment provide the data. The
differences between areas are related to a fishing index (mean value of the annual landings of demersal fish per surface area).

Contaminants from the Channel flow through the Dover Strait into the North Sea where they represent a significant fraction of the
enhanced concentrations observed along the continental coast. Despite numerous previous investigations, the magnitude of this
net flow and its dependency on various forcing factors remain uncertain. The new UK H.F. Radar system, OSCR (Ocean Surface
Current Radar) developed for measuring nearshore surface currents offers a clear opportunity of establishing the magnitude and
nature of this flow. Starting in July 1990, H.F. Radar observations were made in the Dover Strait for five months from the French
coast overlapping (for two months) with five months from the English coast. These measurements involved fully-automised

Blastodinium are chloroplast-containing dinoflagellates which infect a wide range of copepods. They develop inside the gut of
their host, where they produce successive generations of sporocytes that are eventually expelled through the anus of the copepod.
Here, we report on copepod infections in the oligotrophic to ultra-oligotrophic waters of the Mediterranean Sea sampled during

Oceania in the region of the channel in July 1988 and in July 1989. The upper part of the water column in the channel, down to the
bottom of the main pycnocline, was warmer and more saline in 1988. However, the net transport of warm waters with theta
greater-than-or-equal-to 3-degrees-C was oriented to the north, and was rather larger in 1989 (1.8 +/- 2.0 Sv) than in 1988 (1.0

Triplicate porewater depth-profiles of pH and concentrations of total Hg (HgT), methylmercury (MeHg), Fe, Mn, sulfate, total
sulfide, total zero-valent sulfur, organic C and major ions were determined at two sampling dates in a perennially oxygenated
basin and a seasonally anoxic basin from Lake Tantaré, a Canadian Shield lake. The vertical distribution of HgT, MeHg, acid
volatile sulfide, total S, Fe, Mn, Al and organic C were also determined in dated sediment cores from the same lake basins and
from the deepest site of two other lakes, one also located in the Canadian Shield and the other in the Northeastern part of the
Appalachian Mountains. Application of a one-dimensional transport-reaction equation to the dissolved HgT and MeHg profiles

Impact of intensive larval rearing practices in oyster hatcheries : selective processes and loss of
genetic variability (slides)
Provedor de dados: 5
Autores: Taris, Nicolas; Sauvage, Christopher; Boudry, Pierre.
Oysters, like many marine bivalves, are characterized by very high fecundity and low survival rate at early stages of life. Rearing
conditions in hatcheries (i.e. density, feeding, temperature...) are different from those observed in the wild. Additionally, slow
growing larvae are culled by sieving. As previous studies have shown that genetic variability exists for several early development
traits, we aimed to assess if common hatchery rearing practices exert specific selective processes at the larval stage. In order to
avoid possible bias and to increase the number of families studied, we used a mixed-family approach with subsequent parentage
analysis using a recently developed set of three multiplexed microsatellite markers. We studied the variance in...

The electrophoretic study of sarcoplasmic fraction soluble in water or in low ionic strength solutions can be applied to species
identification; in this field isoelectric focusing (IEF) gives excellent results. In this paper thin agarose gels have been used in IEF
for the determination of marine species. The preparation of these agarose gels and the running conditions are described. The use of
agarose gel in IEF is a relatively new technique, different companies market several different agarose ampholyte systems; these
products should be tested to find the most adaptable.

Knowledge of the hydrological regime of an oceanic sector such as the Gulf of Gascony is of vital interest for an ecological study
of fish and other marine species. We have of course many data on this region where the Institute of Maritime Fishing has been
conducting its research for 50 years now. But what was missing was a systematic seasonal study of the entire Gulf covering
several years. A study of this kind, limited to the continental shelf but linked to more extensive research that will be published at
a later time, was undertaken in 1967. The subject of this paper is its first results.
The method used consisted in plotting a

Morphology, limits, origin, and age of salt layer along south atlantic african margin
Provedor de dados: 5
Autores: Pautot, Guy; Renard, Vincent; Daniel, Jacques; Dupont, Jacques.
The west African continental margin between Abidjan (Ivory Coast) and Walvis Boy (Southwcst Africa) was surveyed in 1971 by
the R/V Jean Charcot. Fiftyeight seismic-reflection (flexotir source), bathymetric (3.5 and 12 kc), gravimetric, and magnetic
profiles were obtained. The seaward limit of an evaporitic zone outlined during the survey is at the boundary between continental
slope and continental rise. Variation of depth of this limit as a function of latitude shows the presence of a large offset at 11°S
which seems to be related to an east-east-southeast line of magnetic seamounts cutting into the continental slope.

Provedor de dados: 5
Autores: Gagnaire, Beatrice; Soletchnik, Patrick; Madec, Patrick; Geairon, Philippe; Le Moine, Olivier; Renault, Tristan.
Summer mortality is an important economic concern for the Pacific oyster, Crassostrea gigas, industry all over the world and
particularly in France. Outbreaks appear when oysters are in gonadal maturation. Bivalve defence mechanisms against pathogen
invasion are assumed by circulating cells, the hemocytes. A field experiment was conducted in the Marennes-Oleron Basin
(Charente-Maritime, France) in order to monitor hemocyte parameters, gametogenesis and mortality rates among C. gigas during
7 months from March to September 2002. Diploid (from natural bed and from hatchery) and triploid oysters were placed at 15 cm
or 70 cm above sediment at Marennes-Oleron Basin. Triploid animals were included because they are considered as sterile
animals. Mortality rates...

Provedor de dados: 5
Autores: Tamazouzt, Lakhdar; Chatain, Beatrice; Fontaine, Pascal.
The influence of interaction between light intensity and tank wall colours on survival and growth of perch larvae (Perca fluviatilis
L.) was investigated for 15 days after hatching. Three light intensities (250, 400 and 800 Ix) and four wall colours (black, dark
grey, light grey and white) were used. At the end of the experiment, survival rates ranged between 1% and 26%, and varied
according to the different treatments (P = 0.0001; df = 11). A global effect of light intensity was detected(P = 0.0001; df = 2) and
the highest survival rate was observed under 250 Ix. Survival was also influenced by the tank wall colour(P = 0.0001; df = 3):
light grey showed the best result (17%). The greatest growth in weight and length was observed in tanks with light grey...

This article presents an empirical analysis of the process of valuing and compensating damages resulting from oil pollution at sea.
Observation of recent accidents shows that arriving at a single global estimate of the social cost of an oil spill proves difficult in
most cases. The analysis builds on a historical analysis of the Amoco Cadiz case to show that three types of estima tes can be
considered in practice: (i) estima tes by economists involved as experts in the process, (ii) claims by victims, and (iii)
compensation eventually granted to the claimants. The main factors explaining divergence between these estimates, and their
implications in terms of final payments, are considered. Factors of divergence relate to theoretical and empirical...

Due to hydrophobic and persistent properties, polycyclic aromatic hydrocarbons (PAHs) have a high capacity to accumulate in
sediment. Sediment quality criteria, for the assessment of habitat quality and risk for aquatic life, include understanding the fate
and effects of PAHs. In the context of European regulation (REACH and Water Framework Directive), the first objective was to
assess the influence of sediment composition on the toxicity of two model PAHs, benzo[a]pyrene and fluoranthene using 10-day
zebrafish embryo-larval assay. This procedure was undertaken with an artificial sediment in order to limit natural sediment
variability. A suitable sediment composition might be then validated for zebrafish and proposed in a new OECD guideline for

Marine seabed habitats are highly influenced by the geophysical variables they feature. These are firstly seabed type, topography
and exposure, but in the more inshore areas also include water transparency, salinity, temperature etc. Some relations have been
established in a top-down approach between adequate combinations of these variables and the higher levels of the Eunis
(European Nature Information System) habitat classification which is currently being used to harmonise seabed habitat mapping
throughout Europe. These levels have been referred to as "Marine landscapes", as they are aggregations of a number of lower

The biology, ecology, and dynamics of the deep-sea teleost black scabbardfish in the northeast Atlantic are reviewed. The black
scabbardfish is a commercial bathypelagic species found in the NE Atlantic mostly from Iceland to the Canary Islands and
Western Sahara, at depths from 800 to 1300 m. The spatial structure of its population is still uncertain, although the existence of
one single stock that migrates around the NE Atlantic driven by feeding and reproduction is the most likely hypothesis consistent
with available data. This review is based on data from commercial fisheries off the Faroe Islands, Hatton Bank, the west of the
British Isles, and Portugal (mainland, Azores, and Madeira) and from Icelandic and Scottish scientific surveys collected...

Concern about the impact of fishing on ecosystems and fisheries production is increasing (1, 2). Strategies to reduce these impacts
while addressing the growing need for food security (3) include increasing selectivity (1, 2): capturing species, sexes, and sizes in
proportions that differ from their occurrence in the ecosystem. Increasing evidence suggests that more selective fishing neither
maximizes production nor minimizes impacts (4–7). Balanced harvesting would more effectively mitigate adverse ecological
effects of fishing while supporting sustainable fisheries. This strategy, which challenges present management paradigms,
distributes a moderate mortality from fishing across the widest possible range of species, stocks, and sizes in an eco-system, in...

Japanese clam and hollow oyster spats have been pre-grown under intensive conditions in hatcheries using underground seawater
as thermal resource and as source of nutritional salts for forage seaweed production. The main parameters of this environment
have been followed up and raising conditions have been controlled (spat density, seawater flow, phytoplankton concentration and
temperature). The biological results obtained after interaction processing and the hierarchy of the studied parameters were the
object of an economic analysis for each season, comparing different shellfish pre-growth strategies. This study finally allows us to
be able to present pre-growth intensive methodology that can be passed on to the professional aquaculture industry.

Autores: Kervella, Stephane.
This thesis aims at increasing the general knowledge on sediment dynamics of intertidal flats in the Marennes-Oléron Bay,
according to physical, biological and anthropogenic factors. The conducted research is compound of three complementary
studies: (1) a study of sediment behaviour through applied rheophysics on intertidal superficial sediments; (2) a
hydro-sedimentary study based on identification of the forcing action (physical, biological or anthropogenic) on the intertidal flat
stability over several time scales (from the event to several months); (3) a specific application of the model SiAM-2DH to the
Marennes-Oléron Bay. The surface sediments shows a mechanical behaviour that mainly depends on the fine fraction for a
composition that contains up...

Potential role of compressional structures in generating submarine slope failures in the Niger Delta
Provedor de dados: 5
Autores: Sultan, Nabil; Voisset, Michel; Marsset, Bruno; Marsset, Tania; Cauquil, E; Colliat, J.
The study area, offshore Nigeria, is located in one of the compressional zones within the Niger Delta, which is characterized by
imbricate thrust structures. Although the low mean slope angle (around 2°), bathymetry data from the study area have shown the
existence of several submarine landslides which coincide with known subsurface faulted compressive features. In this paper, we
have focused on a submarine slide occurring in water depths ranging between 1690 and 1750 m. Headwall scars, internal
architecture and associated deposits have been characterized using a combination of 3D seismic data, near-bottom echosounder
seismic profiles, Kullenberg cores and in-situ geotechnical measurements. The slide shows horseshoe shaped headwall scars and
depositional...

Autores: Schmechtig, Catherine; Poteau, Antoine; Claustre, Hervé; D'Ortenzio, Fabrizio; Boss, Emmanuel.
This document does NOT address the issue of chlorophyll-a quality control (either real-time or delayed mode). As a preliminary
step towards that goal, this document seeks to ensure that all countries deploying floats equipped with chlorophyll-a sensors
document the data and metadata related to these floats properly. We produced this document in response to action item 3 from the
first Bio-Argo Data Management meeting in Hyderabad (November 12-13, 2012). If the recommendations contained herein are
followed, we will end up with a more uniform set of chlorophyll-a data within the Bio-Argo data system, allowing users to begin
analyzing not only their own chlorophyll-a data, but also those of others, in the true spirit of Argo data sharing.

Observations sur l'infestation des moules du pertuis breton par mytilicola intestinalis STEUER

Autores: Brienne, Henri.
Mytilicola intestinalis Steuer lives in the mussels of the Breton Sounds (between the Isle of Ré and the Vendee coast). The first
specimens were discovered in January 1960, in a batch of mussels from pilings constructed in the mudflats at Marsilly.
Introduction of this copepod appears to be recent, although it may be responsible for mortality observed in 1930.We thought it of
interest to publish results on the research that has been conducted since the appearance of this parasite and to present the measures
that have been taken to limit its expansion and protect future mussel production.This study concerned mussels cultivated on
"bouchot" pilings in Aiguillon Bay, in its broad sense, from Rocher Point to Digolet Point and on mussels from natural mussel...

Spatial and temporal extension of eutrophication associated with shrimp farm wastewater discharges
in the New Caledonia lagoon
Provedor de dados: 5
Autores: Thomas, Yoann; Courties, Claude; El Helwe, Yasmin; Herbland, Alain; Lemonnier, Hugues.
Shrimp farming in New Caledonia typically uses a flow-through system with water exchange rates as a tool to maintain optimum
hydrological and biological parameters for the crop. Moreover, the effluent shows hydrobiological characteristics (minerals,
phytoplankton biomass and organic matter) significantly higher than that of the receiving environment. Separate surveys were
carried out in a bay (CH Bay) with a medium-size intensive farm (30 ha) (PO) and in a mangrove-lined creek (TE Creek) near a
larger semi-intensive farm (133 ha) (SO). Net loads of nitrogen exported from the semi-intensive farm and the intensive farm
amounted to 0.68 and 1.36 kg ha(-1) day(-1), respectively. At CH Bay, discharge effects were spatially limited and clearly
restricted to...

Sur la présence d'ebriédiens dans le plancton de la baie de Pointe-Noire (A. E. F.)
Provedor de dados: 5
Autores: Rossignol, M.
The Ebridians, marine planktonic flagellates with an internal siliceous skeleton, used to be very numerous in the Tertiary era but
are only represented nowadays by two genera: "Ebria" Borgert (1891) and "Hermesinum" Zacharias (1906). Found successively in
the Baltic Sea, the North Sea, the Mediterranean Sea, the northern Pacific Ocean, the northern and southern Atlantic Ocean, they
had never been observed in tropical seas. Consequently, they were considered as cold or temperate water organisms. Their
presence on the western African coast, at latitude 4° 48' S, in addition to extending their distribution area, seems to invalidate this
point of view. Without drawing any hasty conclusion, it seemed interesting to recall their appearance in the Bay of...

Recent progradation of the magilligan foreland co. Londonderry, northern ireland
Provedor de dados: 5
Autores: Carter, R.w.g.
Since c. 1950 the shoreline at Magilligan Point has prograded by almost 200 m. Sequences of beach ridge and dune development
are directly related to erosion of the adjoining coastline and the efficiency of the sediment transport system. Sand moving along
the shore becomes captured by two overlapping and counteractive drift cells near the Point. Given the present conditions of
sediment scarcity it is thought that this recent progradation is only a short-lived stage in the progressive destruction of the
foreland.

Autores: Reynal, Lionel; Van Buurt, G; Taquet, Marc.
This summary tackles the development of fisheries in the Caribbean using fads. It highlights the principal causes which explain
why, in spite of more than thirty years of experimenting, fishing on fads has not developed as much as had been hoped. Whereas
the deep-sea production of pelagic fish by the continental countries of the region has considerably increased since the early
eighties, that of the Lesser Antilles has grown more slowly. Anchored fads have given the boats of the small-scale fisheries from
three islands (Guadeloupe, Martinique and Curacao) access to these pelagic resources. The various modes of development and
management of the fads observed in each island are described. The first available data are used to provide some indications of

only feeding) and large (> 25kg) Atlantic bluefin tuna (ABFT), Thunnus thynnus, in the Mediterranean Sea, the North Atlantic
and the Gulf of Mexico. The ENM was built bridging knowledge on ecological traits of ABFT (e.g. temperature tolerance,
mobility, feeding and spawning strategy) with patterns of selected environmental variables (chlorophyll-a fronts and
concentration, sea surface current and temperature, sea surface height anomaly) that were identified using an extensive set of
precisely geo-located presence data. The results highlight a wider temperature tolerance for larger fish allowing them to feed in

Significant Atmospheric Boundary Layer Change Observed above an Agulhas Current Warm Cored
Eddy
Provedor de dados: 5
Autores: Messager, Christophe; Swart, S.
The air-sea impact of a warm cored eddy ejected from the Agulhas Retroflection region south of Africa was assessed through both
ocean and atmospheric profiling measurements during the austral summer. The presence of the eddy causes dramatic atmospheric
boundary layer deepening, exceeding what was measured previously over such a feature in the region. This deepening seems
mainly due to the turbulent heat flux anomaly above the warm eddy inducing extensive deep and persistent changes in the
atmospheric boundary layer thermodynamics. The loss of heat by turbulent processes suggests that this kind of oceanic feature is
an important and persistent source of heat for the atmosphere.

Ranges of moisture-source temperature estimated from Antarctic ice cores stable isotope records over
glacial-interglacial cycles
Provedor de dados: 5
Autores: Uemura, R.; Masson-delmotte, V.; Jouzel, J.; Landais, A.; Motoyama, H.; Stenni, B.
A single isotope ratio (delta D or delta O-18) of water is widely used as an air-temperature proxy in Antarctic ice core records.
These isotope ratios, however, do not solely depend on air-temperature but also on the extent of distillation of heavy isotopes out
of atmospheric water vapor from an oceanic moisture source to a precipitation site. The temperature changes at the oceanic
moisture source (delta T-source) and at the precipitation site (delta T-site) can be retrieved by using deuterium-excess (d) data. A
new d record from Dome Fuji, Antarctica spanning the past 360 000 yr is presented and compared with records from Vostok and

Autores: Panserat, Stéphane; Medale, Francoise; Breque, Jeanine; Plagnes Juan, E; Kaushik, Sadasivam.
Hepatic glucose-6-phosphatase (G6Pase) plays an important role in glucose metabolism because it catalyzes the release of glucose
to the circulatory system in the processes of glycogenolysis and gluconeogenesis. The present study was initiated to analyze the
regulation of hepatic G6Pase expression by dietary carbohydrates in rainbow trout. The first step in our study was the
identification of a partial G6Pase cDNA in rainbow trout that was highly homologous to that of mammals. Hepatic G6Pase
activities and mRNA levels were measured in trout fed one of the experimental diets, with or without carbohydrates. We found no
significant effect of intake of dietary carbohydrates on G6Pase Expression (mRNA and activity) 6 hours and 24 hours after

Laboratory radiotracer experiments were performed to study the uptake, assimilation and retention of americium (241Am) and
cesium (134Cs) by the common cuttlefish Sepia officinalis. Uptake and loss kinetics of the radionuclides were measured
following exposure through sediments, seawater and food at different stages of the animal's life cycle. Sediment was found to be a
minor uptake pathway for both radionuclides in juveniles. Following a short seawater exposure, cuttlefish accumulated 241Am
and 134Cs, but only to a limited extent (whole-body CF < 2). Among the cuttlefish organs, branchial hearts and their
appendages displayed the highest degree of uptake for 241Am (CF = 42 and 16, respectively), but these tissues contained low

The French program Coriolis, as part of the French operational oceanographic system, produces the COriolis dataset for
Re-Analysis (CORA) on a yearly basis. This dataset contains in-situ temperature and salinity profiles from different data types.
The latest release CORA3 covers the period 1990 to 2010. Several tests have been developed to ensure a homogeneous quality

Autores: Ganthy, Florian; Soissons, Laura; Sauriau, Pierre-guy; Verney, Romaric; Sottolichio, Aldo.
Innovative flume experiments were conducted in a recirculating straight flume. Zostera noltei meadows were sampled in their
natural bed sediments in the field at contrasting stages of their seasonal growth. The aims of this study were: (i) to quantify the
combined effects of leaf flexibility and development characteristics of Zostera noltei canopies on their interaction with
hydrodynamics; and (ii) to quantify the role of Zostera noltei meadows in suspended sediment trapping and bed sediment
resuspension related with changes in hydrodynamic forcing caused by the seasonal development of seagrasses. Velocity within the
canopy was significantly damped. The attenuation in velocity ranged from 34 to 87% compared with bare sediments and was

Following 1978 and 1981 human poisoning by mussels in Vilaine Bay (France) a survey of potentially toxic dinoflagellates was
conducted in that area in 1982. At the same time paralytic shellfish poison (PSP) analyses were made, the authors studied the
dinoflagellates encountered in the intestinal guts of mussels from January to August 1982. Results failed to demonstrate an
occurrence of PSP producing species, either by toxicological analysis or dinoflagellate persistency in the mussel guts.

Autores: Le Moullac, Gilles; Bacca, Helene; Huvet, Arnaud; Moal, Jeanne; Pouvreau, Stephane; Van Wormhoudt, A.
The response of Crassostrea gigas to prolonged hypoxia was investigated for the first time by analyzing the metabolic branch
point formed by pyruvate kinase (PK) and phosphoenolpyruvate carboxykinase (PEPCK). PK and PEPCK cDNAs were cloned
and sequenced. The main functional domains of the PK sequence, such as the binding sites for ADP/ATP and
phosphoenolpyruvate (PEP), were identified whereas the PEPCK sequence showed the specific domain to bind PEP in addition to
the kinase-1 and kinase-2 motifs to bind guanosine triphosphate (GTP) and Mg2+, specific for all PEPCKs. A C-terminal
extension was detected for the first time in eukaryota PK. Separation of mitochondrial and cytosolic fraction showed that more
than 92% of the PEPCK enzyme activity was cytosolic...

During the ZaiRov2 cruise of the ZaiAngo project (1998-2000) on the passive Congo-Angola margin, several gravity cores were
analyzed for helium isotopic composition of sedimentary pore waters in two cold fluid seepage zones: the Astrid slide area and the
Regab giant pockmark. Gas concentration and isotopic composition are presented along with thermal data in terms of the origin
and circulation of fluids. Helium isotope data lie on a mixing line between bottom seawater and an almost pure radiogenic.
Helium and temperature vertical profiles are well described by the classic diffusion-advection equation. On the basis of He
profiles, we estimate the advection rate on the rim of the pockmark between 1.2 and 2.3 mm/a. The He flux derived for a pure

Synthesis on moored FADs in the North West Pacific region

In early 1980s, fad fisheries were introduced from the Philippines to Japan, mainly to Okinawa. The fisheries have well developed
becoming one of the main fisheries in Okinawa where 210 fads are approved to deploy in 1999. The annual catch by roughly 1
000 boats (most of them are small) is 2500-4000 mt; average catch from one fad is about 20 mt; average catch by one boat on one
day is 73 kilogrammes. fads are also important for easing the fishing pressures on bottom fish stocks. Most of the fads were
deployed and managed by local fishermen's groups that have improved the structures of the system to withstand typhoons. The
catches are strongly depending on the sites, usually the farther offshore, the better the catches. A variety of fishing methods are...

Coastal bays provide habitats for juveniles and adults of many marine species. Mont Saint-Michel Bay (MSMB, France) hosts a
highly diversified fish community and constitutes one of the most important nursery grounds for many commercially exploited
marine species, such as sea bass, flatfish, clupeids and rays in the English Channel. Besides, MSMB also suffers from the massive
invasion of an exotic mollusc, the American slipper-limpet (Crepidula fornicata, L). This species arrived four decades ago and
now represents the main filter-feeder biomass in the bay (150 Mt), an order of magnitude larger than local farmed and natural
shellfishes. Recent analyses underlined the impact of this small gastropod on the trophic structure of this bay and its negative...

Background Biofloc technology (BFT), a rearing method with little or no water exchange, is gaining popularity in aquaculture.
In the water column, such systems develop conglomerates of microbes, algae and protozoa, together with detritus and dead
organic particles. The intensive microbial community presents in these systems can be used as a pond water quality treatment
system, and the microbial protein can serve as a feed additive. The current problem with BFT is the difficulty of controlling its
bacterial community composition for both optimal water quality and optimal shrimp health. The main objective of the present
study was to investigate microbial diversity of samples obtained from different culture environments (Biofloc technology and

Following a review of official control data on shellfish in France, Ingril Lagoon had been identified as a site where positive mouse
bioassays for lipophilic toxins had been repeatedly observed. These unexplained mouse bioassays, also called atypical toxicity,
coincided with an absence of regulated toxins and rapid death times in mice observed in the assay. The present study describes
pinnatoxin G as the main compound responsible for the toxicity observed using the mouse bioassay for lipophilic toxins. Using a
well-characterised standard for pinnatoxin G, LC-MS/MS analysis of mussel samples collected from 2009 to 2012 revealed
regular occurrences of pinnatoxin G at levels sufficient to account for the toxicity in the mouse bioassays. Baseline levels of...

The breeding and cultivation of marine fish species for mariculture

The culture of the marine fish has not made as much progress as other species in aquaculture, for example the marine and
freshwater prawns. The large number of red seabream released each year by the Japanese into the Seto Inland Sea constitutes one
of the major mari-ne fish projects, but the economic benefit for this type of ocean ranching is uncertain, and the cost of the fry is
high. Dover sole and turbot still offer good potential for marine fish culture in Euro-pean and Mediterranean waters, but many of
the farming techniques have been developed for the less valuable but more easily produced plaice. The grey mullet has increasing
farm potential but its commercial markets are limi-ted as it has low value. It is more important as a subsistence...

Autores: Colin, C; Gonella, J; Merle, J.
The intensification of the South Equatorial Current at the surface and the corresponding decrease of the Equatorial Undercurrent
below are associated on a seasonal time scale with a decrease of the temperature at and below the surface; the abrupt increase and
decrease of the surface and subsurface currents in February-March 1983 lead, by geostrophic adjustment, to an uplift of the 20
degree C isotherm, contained within the thermocline, of 14 m. In October-November, the decrease of the equatorial undercurrent
at 85 m depth induces by the same way a vertical displacement of the 17 degree C isotherm of 16 m. Vertical mixing takes place

Variations of b-values at the western edge of the Ryukyu subduction zone, north-east Taiwan
Provedor de dados: 5
Autores: Lin, Jing-yi; Sibuet, Jean-claude; Hsu, S.
Using earthquakes relocated in north-east Taiwan, we estimated b-value distribution along a cross-section located near the
Ryukyu slab edge, and four b-value anomalous areas are evidenced: (1) a high b-value body lying on top of a low Vp, low Vs and
high Vp/Vs sausage-like body was considered as a region of enhanced partial melt or water supply above which seismicity occurs;
(2) beneath the Ilan Plain, an anomalous area characterized by b-values slightly higher than 1.1 might give evidence to the magma
conduits to the Kueishantao Island; (3) above the Ryukyu Wadati-Benioff zone, at depths ranging from 90 to 110 km, a high
b-value anomaly might correspond to the depth where dehydration occurs in the subducting oceanic plate; and (4) a low b-value
area...

Autores: Recy, J.
The data base of the cruise consists of 3900 milles of bathymetry, gravimetry and magnetism profiles and 2000 milles of single
channel seismic reflection profiles; 31 dredgings were also successfully performed. New Hebrides back-arc troughs are located in
the northern and southern part of the rear of the New Hebrides arc. There is no trough in front of the collision/subduction of the
d'Entrecasteaux ridge. The objectives of the cruise were to collect more data concerning the structure and the volcanism in this
area in order to solve the problem of age and origin of the structures observed at the back of the arc.

Autores: Goarant, Cyrille; Merien, Fabrice; Berthe, Franck; Mermoud, Isabelle; Perolat, Philippe.
A molecular typing study on Vibrio strains implicated in shrimp disease outbreaks in New Caledonia and Japan was conducted by
using AP-PCR (arbitrarily primed PCR). It allowed rapid identification of isolates at the genospecies level and studies of
infraspecific population structures of epidemiological interest. Clusters identified within the species Vibrio penaeicida were
related to their area of origin, allowing discrimination between Japanese and New Caledonian isolates, as well as between those
from two different bays in New Caledonia separated by only 50 km. Other subclusters of New Caledonian V. penaeicida isolates
could be identified, but it was not possible to link those differences to accurate epidemiological features. This contribution of

3D modelling of seasonal evolution of Loire and Gironde plumes on Biscay Bay continental shelf
Provedor de dados: 5
Autores: Lazure, Pascal; Jegou, Anne-marie.
A 3D model of the Atlantic shelf has been developed and applied to study shelf dynamics and evolution of hydrology. The model
takes the combined effects of tide, wind, river discharges and surface heat flux into account. Time scales vary from 1 day to
several years. Following a brief description of the model and forcing variables, the behaviour of the Loire and Gironde plumes is
described, first for winter and spring, then over a period of several years, under realistic forcing. The results show that plume
evolution depends on the high Variability of river runoff and winds. Model simulations performed over 7 years (1990 to 1996)
have highlighted several features of these plumes: 1) In early winter and periods of high river runoff, plumes usually spread...

Direct and fast detection of Alexandrium minutum algae by using high frequency microbalance

Autores: Sousa, Celia; Compere, Chantal; Dreanno, Catherine; Crassous, Marie-pierre; Gas, Fabienne; Baus, Beatrice; Perrot,
Hubert.
In this paper, a simple detection of a toxic algae, Alexandrium minutum, was developed using highly sensitive quartz crystal
microbalance. In terms of performance, compared with other conventional analytical tools, the main interest of our immunosensor
is based on a fast and direct detection of these living cells. This system requires the use of one monoclonal antibody directed
against the surface antigen of A. minutum. We demonstrate that the whole living and motile algae are caught and detected. The
high specificity of the biosensor is also demonstrated by testing several other dinoflagellate species. The frequency shift is
correlated to the A. minutum cells concentration. This simple system is potentially promising for environmental monitoring
purposes.

The spatial pattern in hydro-plankton and fish distributions and their relationship were analysed based on the spring 2000 fisheries
acoustic survey. The importance of this survey was that it was a multi-disciplinary platform which collected an extensive set of
parameters in the hydro-plankton leading to a potentially finer description of hydro-plankton conditions and fish habitats. More
than 50 variables were measured on a grid of stations, in four compartments of the ecosystem: hydrology, nutrients, primary
producers and meso-zooplankton. First, a joint analysis of all hydro-plankton compartments was performed using multiple factor
analysis (MFA). The method was used to estimate a compromise factorial space common to all compartments in which the...

Raine, Robin.
Investigations into the phytoplankton of the Bay of Biscay in July 2006 revealed an extensive bloom of an unidentified haptophyte
species. High-resolution sampling techniques identified the region in the vicinity of the mouth of the Loire estuary as an area of
high (106–107 cells l−1) cell densities of the haptophyte in a thin sub-surface layer. This organism dominated the phytoplankton
population regionally. Measurements of the vertical distribution of horizontal shear showed that the population, located at ca. 20
m depth, was confined to a layer lying between two density discontinuities with high shear. Physical measurements indicated that
the population was being advected southeastwards, along the coast. Seaward spreading of the population was also...

Marteilia refringens is a major pathogen of the European flat oyster, Ostrea edulis Linnaeus. Since its description, the lifecycle of
this protozoan parasite has eluded discovery. Attempts to infect oysters experimentally have been unsuccessful and led to the
hypothesis of a complex life-cycle involving several hosts. Knowledge of this life-cycle is of central importance in order to
manage oyster disease. However, the exploration of M. refringens life-cycle has been previously limited by the detection tools
available and the tremendous number of species to be screened in enzootic areas. In this study, these two restrictions were
circumvented by the use of both molecular detection tools and a mesocosm with low biodiversity. Screening of the entire fauna

Scattering of inertial waves by an ocean front - Comments
Provedor de dados: 5
Autores: Klein, Patrice; Treguier, Anne-marie.
Rubenstein and Roberts (1986, hereafter RR86) have studied the scattering of inertial waves by a geostrophic jet. The most
remarkable effect of the jet is to concentrate near-inertial energy in the negative vorticity region. This effect is due to the
horizontal dispersion of near-inértial waves. It is demonstrated by RR86 Using a stratified linearized model. A similar result has
been obtaîned by Kunze (1985) using a ray-tracing approach and bas been confirmed by observations (Kunze and Stanford 1984).
Another result of RR86 concems the mixed layer depth variations. Their Figs. 3 and 8 show a systematic downwelling in the
negative vorticity region of the jet and systematic upwelling in the positive vorticity region. Although large upwellings and...

Potential feeding and spawning habitats of Atlantic bluefin tuna in the Mediterranean Sea
Provedor de dados: 5
Autores: Druon, Jean-noel; Fromentin, Jean-marc; Aulanier, Florian; Heikkonen, Jukka.
Atlantic bluefin tuna Thunnus thynnus (ABFT) is a fish of high market value which has recently become strongly overexploited,
notably in the Mediterranean Sea. This area is an essential habitat for ABFT reproduction and growth. We present here an
approach for deriving the daily mapping of potential ABFT feeding and spawning habitats based on satellite-derived sea surface
temperature (SST) and chl a concentration. The feeding habitat was mainly derived from the simultaneous occurrence of oceanic
fronts of temperature and chl a content while the spawning habitat was mostly inferred from the heating of surface waters.
Generally, higher chl a contents were found to be preferred for the feeding habitat and a minimum SST value was found for the
spawning habitat....

Autores: Gatesoupe, Joel.
Formaldehyde was used to disinfect Artemia cysts and nauplii, while introducing two probiotics in the enrichment process:
Bactocell (Pediococcus acidilactici) and Levucell (Saccharomyces cerevisiae). The disinfectant was selected due to its potential
compatibility with probiotics, since it was more effective against Gram-negative bacteria than against lactic acid bacteria and
yeast. However, the presence of formaldehyde reduced the intake of P. acidilactici in Artemia. Consequently, the disinfection was
stopped before Bactocell supplementation to the nauplii fed to pollack (Pollachius pollachius) larvae. The mean weight of pollack
was higher with this probiotic treatment. Growth was even better with the combination of Levucell and Bactocell, but the yeast...

Recent studies have revealed differences between the fluorescence spectra of coastal and open seawater. We investigate here the
extent to which abiotic parameters such as pH, ionic strength and concentration of dissolved fluorescent matter could be related to
this phenomenon. First, pH effect was addressed alone. Second, a 2 super(3) factorial experimental design was used to estimate
the individual and/or combined contribution of the parameters mentioned above to the spectroscopic characteristics of dissolved
organic matter represented here by the Suwannee River Fulvic Acid. High pH variations modify the spectroscopic characteristics
of organic matter both qualitatively and quantitatively and those effects seem to be related to the dissociation of the...

For developing efficient diets, two sets of experiments examined whether the use and allocation of dietary protein can be traced by
labelling with stable isotopes (N-15 and C-13) in two culture fish (Oncorhynchus mykiss and Sparus aurata). In the first
experiment, natural abundance and tissue distribution of these isotopes were determined, by measuring the delta C-13 and delta
N-15 values by isotopic ratio mass spectrometry, in fingerlings (14-17 g) adapted to diets differing in the percentage of fish meal
replacement by plant protein sources. For both species, delta N-15 and delta C-13 were greater in tissues with higher protein and
lower lipid content. Delta N-15 of diets and tissues decreased as replacement increased, suggesting delta N-15 can be used...

Stable oxygen and hydrogen isotopic tracers in Amazon shelf waters during Amasseds
Provedor de dados: 5
Autores: Karr, Jd; Showers, Wj.
A detailed hydrographic survey of the water column of the Amazon shelf was performed using stable oxygen and hydrogen
isotopes to determine the source and fate of waters on the shelf. delta(18)O-H2O and deltaD measurements were made on water
column samples from approximately 60 stations (three depths per station) which were each collected during four Amasseds (A
Multidisciplinary Amazon Shelf SEDiment Study) cruises: I8909-August 1989, falling river discharge; I9002-March 1990, rising
river discharge; I9004-May 1990, peak discharge: I9113-November 1991, minimum discharge. Isotopes were compared with
salinity and temperature measurements in order to identify water masses and mixing. The characteristics (salinity, temperature,
delta(18)O, deltaD and d) are...

Buried fluvial incisions as a record of Middle-Late Miocene eustasy fall on the Armorican Shelf (Bay
of Biscay, France)
Provedor de dados: 5
Autores: Paquet, Fabien; Menier, David; Estournes, Guilhem; Bourillet, Jean-francois; Leroy, Pascal; Guillocheau, Francois.
High-resolution seismic data have been acquired in June 2008 on the Armorican Shelf (AS), in the northern Bay of Biscay, in
order to reassess its stratigraphic architecture in detail and to study the impact of eustasy, tectonic and sediment delivery on the
margin sedimentary record. Several profiles show fluvial-type incisions of several tens of meters (up to 54 m) associated to a
widespread erosion surface. Several hypotheses are proposed for the stratigraphic position of this surface and incisions. We
suggest Middle to Late Miocene age. Considering the relatively quiescent tectonic activity of the margin, we infer that the relative
sea-level fall responsible of aerial incision on the Miocene shelf is eustasy-related. We propose the attested...

Etude de la smoltification de salmonidés migrateurs par le dosage de l'activité (Na+ -K+) ATPasique
branchiale
Provedor de dados: 5
Autores: Bousseau, Marie-hélène.
Les salmonidés migrateurs sont des téléostéens anadromes. Les poissons matures remontent les rivières pour frayer. Les jeunes
saumons, appelés parrs, vivent un temps plus ou moins long en rivière puis subissent un ensemble de modifications
morphologiques, physiologiques et comportementales qui les préadapte à leur vie future en eau de mer et qui se termine par la
dévalaison des saumons dits alors smolts. Ce processus s'appelle smoltification. Il est lié à un rythme biologique endogène
synchronisé et modulé par les facteurs externes, la température et la photopériode (HOAR, 1976, 1988).

Après le naufrage de l'Erika, la question s'est rapidement posée de l'impact des hydrocarbures sur la santé des coquillages, car la
pollution concernait des zones de production conchylicoles. Le suivi zoosanitaire en place dans ces zones permettait d'avoir des

In the last decades, shellfish farming and in particular ostreiculture have developed in a significant way in France.
Marennes-Oleron (Charente-Maritime) basin is the first French producer of oysters. But this area is also subjected to many
recurring pollution, brought mainly by the Charente river. The recrudescence using of herbicides in agriculture including atrazine
implies the transfer towards the aquatic environment of new pollutants in estuarine areas. Moreover industrial rejections bring
many heavy metals in these same estuarine areas. It is appropriate of wondering on harmful effects of all these pollutants on the
animals living in these areas, particularly oysters. Bivalve molluscs have been postulated as ideal indicator organisms because

Le dragage des huîtres portugaises en gironde

Autores: Le Dantec, Jean; Marteil, Louis; Trochon, P.
To sum up, the Gironde River estuary, the main Portuguese oyster production area, is visited each year by a large number of boats
which come for a few days to dredge its natural deposits. The gradual increase of their number and of the efficiency of the fishing
gear, as well as the fluctuating fishing performance show the need to define the basis of a rational exploitation in order to protect
these oyster banks. Based on the data collected from 1956 to 1958 we set up a work schedule for the visitation commission which
should meet at the end of winter, and we put figures on the assessment basis that should help this commission to determine the
duration and intensity of each year's exploitation.

The measurement of the fluorescent 4-methyl-7-coumarinylamine released from the hydrolysis of a non-fluorescent peptide model
substrate by exoproteolytic enzymes has been adapted to flow injection analysis (FIA). FIA allows samples to be processed very
quickly (less than 2 min. for triplicate determinations) with good sensitivity (< 0.1 muM) and reproducibility (relative standard
deviation < 3 % at the 0.2 muM level). In a coastal marine pond, exoproteolytic activity was closely related to bacterioplankton
biomass. The high activity measured in pond water (maximum velocity: V(M) almost-equal-to 1.46 to 2.54 muM.h-1) emphasizes
the importance of dissolved protein hydrolysis for bacterial growth and for dissolved organic nitrogen cycling. The mean...

Comparison of 0- and 2-group otolith elemental signatures to discriminate Solea solea nurseries in the

Provedor de dados: 5
Autores: Durieux, Eric D. H.; Labonne, Maylis; Begout, Marie-laure; De Pontual, Helene.
The common sole Solea solea (L.) is a commercially important and widely distributed flatfish of the North-East Atlantic. For the
Bay of Biscay stock, sole nurseries display differences in terms of quantity and quality. In fine the measure of the quality of a
habitat for juveniles of a particular species is expressed by the contribution to the recruitment into the adult population.
Understanding this connectivity between juvenile and adult habitats, i.e. evaluating the contribution of each nursery to a single
adult stock appears essential in terms of stock management. However, this critical link is still missing for the Bay of Biscay sole
stock. Determining if nurseries could be discriminated using otolith elemental composition analysis constitutes the...

On the effect of tidal flats on the hydrodynamics of the Tagus estuary
Provedor de dados: 5
Autores: Fortunato, Ab; Oliveira, A; Baptista, Am.
The effects of tidal flats on the hydrodynamics of the Tagus estuary are analysed using an accurate high-resolution shallow water
model, supported by field data. Tidal flats act mainly as energy filters, rather than sinks, transferring energy from astronomic to
non-linear frequencies. They also play a major role in determining the strong resonance mode that amplifies semi-diurnal
constituents. We show that the upper estuary, with extensive tidal flats, has an increasing accretion rate. This "filling-up" results
from a positive feedback between sediment deposition and the hydrodynamics: accretion in the upper estuary lengthens the
duration of ebbs, decreasing sediment flushing and further increasing accretion.

Distribution of echinoderm larval populations in the geostrophic frontal jet of the eastern Alboran Sea
Provedor de dados: 5
Autores: Pedrotti, Ml; Fenaux, L.
A survey of-selected echinoderm larvae and postlarvae was conducted during Almofront-1 cruise in the eastern Alboran Sea
(Mediterranean Sea). In the study zone, surface waters from the Atlantic current enter via Gibraltar forming a hydrologically
complex area with associated eddies and gyres. The distribution pattern of echinoderm larvae is described and related to specific
biological and physical frontal processes responsible for larval retention or dispersal. In the part of Alboran Sea, influenced by
Mediterranean waters, echinoderm larvae and postlarvae were quite scarce in comparison to the stations localised in the Atlantic
jet and sites under influence of Atlantic waters where species richness and larval abundance were higher. The Anticyclonic gyre...

Autores: Buestel, Dominique; Pouvreau, Stephane.
Results of research concerning the food of the pearl oyster Pinctada mai margaritifera are presented, by taking Takapoto atoll
(Tuamotu archipelago, French Polynesia) as a study site. Monthly sampling of several parameters representative of bivalve
environment and food (water temperature, salinity, mineral and organic matter, proteins, lipids and carbohydrates, chlorophyll a
and phaeopigments) confirm and increase knowledge of the Takapoto lagoon hydrobiology. The variability of these parameters
was analysed. Takapoto lagoon showed a remarkable spatial stability. Temporal variations showed a low seasonal trend. Local
meteorology (wind, precipitation) had an influence on short-term variability (especially for mineral matter). Night and day rhythm

Contribution à l'étude de la sédimentation et de la géologie sous-marine dans le golfe de Gascogne

Autores: Berthois, Léopold.
Up until now, the Bay of Biscay has been the focus of only a very small number of studies. In its lithologic map of French seas,
Delesse (1872) identified the sediments based only on the soundings of the French Naval Hydrographic Service. Thoulet's (1904)
submarine lithologic map was made using the same information completed by the analysis of a small number of dredgings (J.
Thoulet 1901), which enabled the author to correct Delesse's data, especially in the area commonly called "la grande vasière" (the
great mudflat). In 1925, L. Dangeard conducted, on board the "Pourquoi Pas?", a few dredgings in the Bay of Biscay. The results
will be analysed in this work. In 1935, J. Furnestin carried out a number of very important observations which will also be...

One of the leading challenges in marine science and governance is to improve scientific guidance of management measures to
mitigate eutrophication nuisances in the EU seas. Too few approaches integrate the eutrophication process in space (continuum
river-ocean) and in time (past, present and future status). A strong need remains for (i) knowledge/identification of all the
processes that control eutrophication and its consequences, (ii) consistent and harmonized reference levels assigned to each
eutrophication-related indicator, (iii) identification of the main rivers directly or indirectly responsible for eutrophication
nuisances in specific areas, (iv) an integrated transboundary approach and (v) realistic short term and long term nutrient

Analyse et estimation des puissances de pêche
Provedor de dados: 5
Autores: Laurec, Alain.
An analysis of the fishing power concepts leads to a distinction between local fishing power (at a given location). and overall
fishing power. Overall fishing power takes into account the ability to detect and quickly exploit rich areas. In order to estimate
local fishing power it is necessary to compare the catches of different ships operating in neighbouring areas. Such a comparison
performed on two ships will give an estimate of their relative fishing powers. The closer the two ships are, the more reliable will
be the estimate. A weighting function must be used, and this function is related to the spatial heterogeneity of the fish density.
Such a function is provided by the variogram as defined by Matheron (1965). [NOT CONTROLLED OCR]

Bilan 1992 de la contamination des côtes françaises par les composés organostanniques
Provedor de dados: 5
Autores: Michel, Pierre; Averty, Bernard.
Au cours du printemps 1992, un échantillonnage systématique a permis d'évaluer le niveau de la contamination des côtes
françaises par les composés organostanniques. Le tributyl étain (TBT) a été mesuré dans la phase dissoute avec ses produits de
dégradation dibutyl étain (DBT) et monobutyl étain (MBT). Les concentrations mesurées restent importantes dans les zones
portuaires et les zones de mélanges. Ces concentrations sont le plus souvent excessives lorsqu'on se réfère au seuil toxique de
1ng.1-1 pour lequel des effets sont connus sur l'huître et certains autres mollusques. Les trois façades maritimes françaises ont été

Genetic investigations on the caffeine and chlorogenic acid relationship in an interspecific cross
between Coffea liberica dewevrei and C-pseudozanguebariae
Provedor de dados: 5
Autores: Ky, Chin-long; Barre, Philippe; Noirot, Michel.
The objective of the paper was to identify the number of major loci explaining caffeine content in coffee seeds. Investigations
were based on previously published results: (1) Caffeine binds to chlorogenic acids in a 1:1 molecular ratio; (2) Between species,
the caffeine content is correlated to the chlorogenic acid content; (3) Only a part of chlorogenic acids is bound to caffeine.
Especially, the content ratio between caffeine and chlorogenic acids varied between species. For identifying the number of major
loci, a quantitative trait locus (QTL) approach was carried out using an interspecific cross between two highly differentiated
species-Coffea liberica dewevrei and Coffea pseudozanguebariae, the latter being a caffeine-free species. As main finding,...

Diet overlap between harbour porpoise and bottlenose dolphin: An argument in favour of
interference competition for food?
Provedor de dados: 5
Autores: Spitz, Jérôme; Rousseau, Yann; Ridoux, Vincent.
In aquatic ecosystems, competitive interactions are occasionally described. Violent attacks on harbour porpoises by bottlenose
dolphins were reported and it was proposed that this behavior could result from competitive interactions for food. This hypothesis
implies that the two predators should share all or part of they prey range. In this work, we describe the diets of each predator in the
Bay of Biscay and adjacent areas from stomach content analysis of stranded animals. The diet of the harbour porpoise was mostly
composed of small schooling fish living close to the seafloor (98 percent by mass). The diet of the bottlenose dolphin was
characterised by the presence of large specimens of demersal fish (91 percent by mass) and cephalopods. Several prey...

Autores: Lebrun, Jeremie D.; Perret, Marine; Uher, Emmanuelle; Tusseau-vuillemin, Marie-helene; Gourlay-france, Catherine.
The biodynamic and saturation models offer promising lines of enquiry to predict the bioaccumulation of metals by aquatic
organisms. However, in order to construct these models, the accumulation strategies have to be defined for each metal/organism
couple in controlled conditions. This study aims at modelling the waterborne bioaccumulation of Ni and the influence of the
water's geochemical properties on this process in a crustacean that is widely distributed in Europe, Gammarus pulex. In the
laboratory, G. pulex was exposed to several Ni concentrations (from 0.001 to 100 mg L(-1)) in aquatic microcosms. Our results
show that G. pulex is very tolerant to Ni (LC50(48 h) = 477 mg L(-1) Ni). Time course experiments enabled the construction of a

Human enteric viruses discharged in raw sewage are hightly resistant and may be detected in surface waters, coastal areas and
shellfish. Whereas noroviruses, responsible for relatively benign acute gastroentritis, are the most common agents implicated in
shellfish borne outbreaks, other human viruses which cause severe human diseases, such as hepatitis A virus, may also be
transmitted. Environmental studies have demonstrated that virus concentrations detected in shellfish are higher than in
surrounding waters. This concentration may explain the high prevalence of noroviruses detected in various shellfish species
collected in different countries. If many questions remain regarding viral contamination of shellfish, the most important seems to

A strong interest has been focused from several years on the algae pathway for energy production, especially for transportation
fuels called third generation biofuel or G3 biofuel, and mainly from microalgae route, considering it could be a high potential
alternative strategy for renewable energy and fuel production. Algae, and especially microalgae, present significant advantages
compared with land resources, such as much higher productivity and lack of competition with food applications. Nevertheless,
based on current knowledge, the production of an algae biomass for energy remains a difficult target to reach, due to the numerous

impact. To identify this peculiar tsunami signature, the Atacames Promontory, Ecuador, was chosen as a case study (another
example is the shelf of the Nile delta, Egypt). The area is tectonically very active, hosts earthquakes among the most powerful
recorded, as well as areas of slope instabilities that have triggered significant submarine landslides in the past (several cubic
kilometres of volume). Both types of events are likely to be tsunamigenic. To examine the tsunami behaviour at the coastal area of

In September 2014, ICES was tasked with assessing the MSFD GES descriptor 6 (sea-floor integrity) issues, focusing on methods
and bounds for setting Good environmental status (GES). The results of this D6 workshop provided a guidance report with
dedicated recommendations. However, when the D6 report was reviewed during the Marine Framework Directive Common
Implementation Strategy meeting (MSFD CIS) of the Working Group on Good Environmental Status (WG GES) in October 2014,
it was highlighted that more details will be required to guide Member States (MS) on: i) how to link higher level criteria to
specific indicators and ii) how these indicators could be implemented in national monitoring and assessment programmes. The

Recovery of valuable soluble compounds from washing waters generated during small fatty pelagic
surimi processing by membrane processes
Provedor de dados: 5
Autores: Dumay, Justine; Radier, Severine; Barnathan, Gilles; Berge, Jean-pascal; Jaouen, Pascal.
This work focuses on the treatment of washing waters coming from surimi manufacturing using ultrafiltration technology at a
laboratory scale. Four membrane materials (poly-ether sulfone, polyacrilonytrile, poly vinylidene fluoride and regenerated
cellulose) and 5 Molecular Weight Cut-Off (from 3 to 100 kDa) have been studied at bench laboratory scale using the pilot
Rayflow (R) 100, commercialised by Rhodia Orelis. The investigation deals with the ability for membranes to offer a high
retention of biochemical compounds (proteins and lipids). Results obtained during adsorption tests showed that the regenerated
cellulose material seems to be the most appropriate with regards to pore size reduction due to the protein-adsorption. During the
ultrafiltration of...

Wave and turbulence measurements at a tidal energy site
Provedor de dados: 5
Autores: Filipot, Jean-francois; Prevosto, Marc; Maisondieu, Christophe; Le Boulluec, Marc; Thomson, Jim.
This work presents the analysis of wave and turbulence measurements collected at a tidal energy site. A new method is introduced
to produce more consistent and rigorous estimations of the velocity fluctuations power spectral densities. An analytical function is
further proposed to fit the observed spectra and could be input to the numerical models predicting power production and structural
loading on tidal turbines. Another new approach is developed to correct for the effect of the Doppler noise on the high frequencies
power spectral densities. The analysis of velocity time series combining wave and turbulent contributions demonstrates that the
turbulent motions are coherent throughout the water column, rendering the wave coherence-based methods not...

Two profiling floats, equipped with nitrate concentration sensors were deployed in the northwestern Mediterranean from summer
2012 to summer 2013. Satellite ocean color data were extracted to evaluate surface chlorophyll concentration at float locations.
Time series of mixed layer depths and nitrate and chlorophyll concentrations were analyzed to characterize the interplay between
the physical-chemical and biological dynamics in the area. Deep convection (mixed layer depth > 1000 m) was observed in
January–February, although high-nitrate surface concentrations could be already observed in December. Chlorophyll increase is
observed since December, although high values were observed only in March. The early nitrate availability in subsurface layers,

Precision and accuracy of fish length measurements obtained with two visual underwater methods

Autores: Rochet, Marie-joelle; Cadiou, Jean-francois; Trenkel, Verena.
During the VIITAL cruise in the Bay of Biscay in summer 2002, two devices for measuring the length of swimming fish were
tested: 1) a mechanical crown that emitted a pair of parallel laser beams and that was mounted on the main camera and 2) an
underwater auto-focus video camera. The precision and accuracy of these devices were compared and the various sources of
measurement errors were estimated by repeatedly measuring fixed and mobile objects and live fish. It was found that fish mobility
is the main source of error for these devices because they require that the objects to be measured are perpendicular to the field of
vision. The best performance was obtained with the laser method where a video-replay of laser spots (projected on fish bodies)

skewness coefficients of sea-surface-slope probability density function (pdf) for wind speed less than 10 m/s and effects from
wave breaking for wind speed greater than 10 m/s. Simulated D-c values are exclusively compared with the empirical geophysical
Doppler model function named CDOP, for hh and vv polarizations, various wind conditions, and incidence angles. Good
agreement is found overall between CDOP and simulated D-C values. The overall bias for simulated Dc-vv with and without

Azaspiracids (AZAs) are marine biotoxins produced by dinoflagellates that can accumulate in shellfish, which if consumed can
lead to poisoning events. AZA7–10, 7–10, were isolated from shellfish and their structures, previously proposed on the basis of
only LC–MS/MS data, were confirmed by NMR spectroscopy. Purified AZA4–6, 4–6, and 7–10 were accurately quantitated by
qNMR and used to assay cytotoxicity with Jurkat T lymphocyte cells for the first time. LC–MS(MS) molar response studies
performed using isocratic and gradient elution in both selected ion monitoring and selected reaction monitoring modes showed
that responses for the analogues ranged from 0.3 to 1.2 relative to AZA1, 1. All AZA analogues tested were cytotoxic to Jurkat T

The quantitiative requirements for protein have been determined in P. serratus reared from the post-larval stage to the 4th month.
It appears that the apparent optimum percentage of protein in the diet is a minimum of 60%. At the 8th month, the mean wt of
prawn reared with the best artificial diet (diet IV) is only 49% of the wt of shrimp reared with the digestive gland of Patella as a
diet. The prawns reared to 4th month on a low-protein diet then reared on a natural diet until the 8th month, show important
compensatory growth. However, the prawns do not achieve the wt of the control population, their average wt representing only

Autores: Cognard, J. Y.; Creac'Hcadec, R.; Maurice, J.; Davies, Peter; Peleau, Michel; Da Silva, L. F. M.
Generally, adhesives are viscoelastic-plastic materials, for which the development of viscosity and plasticity varies depending on
the type of adhesive and the stress state. Various models exist to represent the yield surface, or the so-called elastic limit, taking
into account the two stress invariants, hydrostatic stress and von Mises equivalent stress. Moreover, to develop precise
pressure-dependent constitutive models, it is necessary to have a large experimental database in order to accurately represent the
adhesive strains which are strongly dependent on the tensile-shear loading combination. Under quasi-static loadings, for a given
strain rate range viscous effects can be neglected, but only a few experimental results are available to model the...

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....

Dans le cadre du Système national d'Information sur l'Eau, mis en place par le Ministère de l'Ecologie et du Développement
Durable, l’Institut national de recherche marine (Ifremer) opère de façon coordonnée à l'échelle du littoral français trois
programmes nationaux de surveillance : le réseau de contrôle microbiologique (REMI), le réseau de surveillance du phytoplancton
et des phycotoxines (REPHY), le Réseau d'Observation de la Contamination Chimique (RNO). Le suivi des phycotoxines dans les
coquillages réalisé par le REPHY est sous maîtrise d'ouvrage du Ministère de l'Agriculture et de la Pêche. Sous l’impulsion de la
Directive européenne Cadre sur l'Eau (DCE), le réseau de surveillance benthique (REBENT) est en voie d’extension nationale.

Les mollusques exploités commercialement se divisent en trois classes : les pélécypodes ou mollusques bivalves, les gastéropodes
et les céphalopodes. Ils présentent un intérêt économique appréciable par la diversité des espèces existantes ainsi que par leurs
possibilités de conservation. La majorité des travaux réalisés à ce jour se rapportent aux mollusques bivalves (Hansen et Aagaard,
1969) et concernent les huîtres (Crépey et Han-Ching, 1975), les huîtres congelées sous diverses formes aux U.S.A. (Mc Kee et

The notions of safety and working conditions on board trawlers are too often integrated when the building of the vessel is coming
to the end. This guide gives the most relevant elements to deal with this problem right from the start of the design. It takes in
account the development of deep sea fishing and the adoption of new type of storage of fish on board: containers and boxes. Data
collected on board of different type of trawlers has let to write a practical book intended for fishing vessels's designers : naval

Les images évoquant le littoral breton sont bien souvent celles de falaises en avant desquelles émergent une multitude de récifs ou
d'îlots rocheux. Pourtant entre les secteurs de côte rocheuse s'étendent des terres basses, situées pour la plupart au-dessous du
niveau des plus hautes marées. Leurs limites demeurent souvent fort indécises et présentent en outre une grande instabilité du fait
de l'érosion, de la sédimentation, des oscillations du niveau marin et des mouvements tectoniques qui les déplacent
continuellement.

How do demersal fishing fleets interact with aggregate extraction in a congested sea?
Provedor de dados: 5
Autores: Marchal, Paul; Desprez, Michel; Vermard, Youen; Tidd, Alex.
The effects of the aggregate extraction intensity and the distance to extraction sites on the distribution of fishing effort were
investigated for a broad selection of French and English demersal fleets operating in the Eastern English Channel. The most
prominent result was that most fleets fishing near to aggregate extraction sites were not deterred by extraction activities. The
fishing effort of dredgers and potters could be greater adjacent to marine aggregates sites than elsewhere, and also positively
correlated to extraction intensity with a lag of 0–9 months. The distribution of fishing effort of French netters remained consistent
over the study period. However, it is of note that the fishing effort of netters has increased substantially in the...

Passive Margin Development. A Consequence of Specific Convection Patterns in a Variable Viscosity
Upper Mantle
Provedor de dados: 5
Autores: Meissner, R.
Simple thermodynamics calculations are applied to processes of a rising plume within an environment of an upward directed
gradient of viscosity in the uppermost mantle. Four stages of the development of passive margins are described. Following an
initial regional uplift strong lateral movements are induced at asthenospheric levels, stretching the overlying lithosphere. In the
second stage plume material also enters the low viscosity lower crust, replacing continental material and forming a new, higher
crust-mantle boundary by gravitational differentiation. The inital phase lag between the laterally intruding plume material and the
rest of the lithosphere disappears once the continent is rifted and sea floor spreading is established (= stage 3). Finally, at...

Provedor de dados: 5
Autores: Fauconnet, Laurence; Trenkel, Verena M.; Morandeau, Gilles; Caill-milly, Nathalie; Rochet, Marie-joelle.
To implement an ecosystem approach to fisheries management, there is a need to characterize the total pressure exerted by
fisheries at the community level. French onboard observer data were used to derive catch metrics and compare fishing distribution
across community components between two sites in the Southern Bay of Biscay. Sample-based rarefaction curves were used to
standardize metrics across different active and passive gears, and correct for sample size differences. Six metrics for species,
length and functional catch composition were tested. Length and functional metrics were found the most relevant metrics to
highlight differences in catches between gears, sites, and gear-site interactions. Significant differences were found between gears,

Vertical motion in the eastern Equatorial Pacific inferred from drifting buoys
Provedor de dados: 5
Autores: Hansen, D V; Paul, Ca.
Surface current measurements have been obtained from the Eastern tropical Pacific Ocean by means of drifting buoys tracked by
the NIMBUS and ARGOS satellite systems since 1977. Near-equatorial divergence of Ekman transport is indicated qualitatively
by persistent avoidance of the Equator by drifters. Upwelling velocity and transport were estimated from the horizontal divergence
of surface current fields obtained by optimum interpolation of overall and monthly composite data. The estimated divergence is
predominantly meridional. Average upwelling velocity and transport in the region 1.5 degree N-1.5 degree S, 80 degree W-130
degree W are estimated to be 1.5 m d super(-1) and 32 x 10 super(6) m super(3) s super(-1). Seasonal variation of the estimated...

Various observations pointed out that cores performed with gravity piston corer show signifi cant distortions mainly located at the
top of the core. A series of 15 cores were performed at the same location on a submarine sand wave (Var canyon, France). Six
different settings of the corer – three freefall heights and three slacks of the piston cable – were tested, including duplicates. Two
accelerometers recorded simultaneously the movements of the core tube and the movements of the triggering arm. Then the z
displacements were obtained by a double integration versus time of the measured acceleration. The analyses of results allowed the
authors to estimate the amplitude and the duration of the elastic recoil of the aramid cable, andto distinguish four steps...

Ecological network analysis was applied in the Seine estuary ecosystem, northern France, integrating ecological data from the
years 1996 to 2002. The Ecopath with Ecosim (EwE) approach was used to model the trophic flows in 6 spatial compartments
leading to 6 distinct EwE models: the navigation channel and the two channel flanks in the estuary proper, and 3 marine habitats
in the eastern Seine Bay. Each model included 12 consumer groups, 2 primary producers, and one detritus group. Ecological
network analysis was performed, including a set of indices, keystoneness, and trophic spectrum analysis to describe the
contribution of the 6 habitats to the Seine estuary ecosystem functioning. Results showed that the two habitats with a functioning

Concomitant enrichments of uranium, molybdenum and arsenic in suboxic continental-margin

Autores: Legeleux, F; Reyss, Jl; Bonte, P; Organo, C.
Elemental analyses were carried out by Neutron Activation Analysis on eleven sediment cores from the North-East Tropical
Atlantic, collected at two sites of the French EUMELI programme. Total uranium, molybdenum and arsenic concentrations
increase from the surface to about 20 cm depth in cores from the eutrophic site, but remain constant in cores from the mesotrophic
site. These profiles clearly highlight an enrichment of the three elements in the sediments from the eutrophic site, linked to the
suboxic conditions encountered in these sediments. This entrapping of uranium in suboxic sediments, observed in previous studies
(Barnes and Cochran, 1990; Klinkhammer and Palmer, 1991), is thus confirmed at the EUMELI eutrophic site. Furthermore, other

Live foods such rotifers and Artemia are still indispensable for mass propagation of larval fish. At present, more than 20 fish and
crustacean species are mass produced in Japanese governmental fish farming centres and private hatcheries. Fry are either released
into the coastal areas or used for commercial cultivation. This culture technology is rapidly developing with new species being
introduced each year and larval rearing is increasingly identified as the number one constraint. Artemia is used most extensively,
particularly for the mass production of Kuruma prawn, Penaeus japonicus .

In situ clearance rate (CR) and biodeposition of the black pearl oyster, Pinctada margaritifera, were followed during several field

particulate inorganic matter (PLM, mg l(-1)), and particulate organic matter (POM, mg l(-1)) were related to meteorological
conditions, especially wind speed. As a general case, POM and PLM increased with wind speed. Nevertheless, PLM increased
faster than POM so that the organic content (OC, %) of the TPM decreased progressively when wind speed increased. These TPM
variations induced direct changes in feeding processes of P. margaritifera. CR (l h(-1)) averaged 22 l h(-1) for a pearl oyster of 1 g

The environment is impacted by natural and anthropogenic disturbances that occur at different spatial and temporal scales, and
that lead to major changes and even disequilibria when exceeding the resiliency capacities of the ecosystem. With an annual mean
flow of 1700 m(3) s(-1), the Rhone River is the largest of the western Mediterranean basin. Its annual solid discharges vary
between 2 and 20 Mt, with flood events responsible for more than 70% of these amounts. In the marine coastal area, close to the
mouth, both flocculation and aggregation lead to the formation of fine-grained deposits, i.e. the prodelta. This area is characterized
by sediment accumulation rates up to 20-50 cm yr(-1) and high accumulations of particle reactive contaminants such as...

very low : only 3 % of the diets are recovered by filtration after 4 hours in water. The addition of 10 % gelatin impro-ves slightly
this stability (13 to 25). While encapsulation with nylon considerably increases the water-standing capacity of diets (56 to 66 %),
the best results are obtained with the particles encapsulated using natural polymers (74 to 79 %). Though...

Observed acidification trends in North Atlantic water masses
Provedor de dados: 5
Autores: Vazquez-rodriguez, M.; Perez, F.f.; Velo, A.; Rios, A. F.; Mercier, Herle.
The lack of observational pH data has made it difficult to assess recent rates of ocean acidification, particularly in the high
latitudes. Here we present a time series that spans over 27 yr (1981-2008) of high-quality carbon system measurements in the
North Atlantic, which comprises fourteen cruises and covers the important water mass formation areas of the Irminger and Iceland
Basins. We provide direct quantification of acidification rates in upper and intermediate North Atlantic waters. The highest rates
were associated with surface waters and with Labrador Sea Water (LSW). The Subarctic Intermediate and Subpolar Mode Waters
(SAIW and SPMW) showed acidification rates of -0.0019 +/- 0.0001 and -0.0012 +/- 0.0002 yr(-1), respectively. The deep

Cone penetration testing to assess slope stability in the 1979 Nice landslide area (Ligurian Margin, SE
France)
Provedor de dados: 5
Autores: Steiner, Alois; Kopf, Achim J.; Henry, Pierre; Stegmann, Sylvia; Apprioual, Ronan; Pelleau, Pascal.
In the landslide-prone area near the Nice international airport, southeastern France, an interdisciplinary approach is applied to
develop realistic lithological/geometrical profiles and geotechnical/strength sub-seafloor models. Such models are indispensable
for slope stability assessments using limit equilibrium or finite element methods. Regression analyses, based on the undrained
shear strength (su) of intact gassy sediments are used to generate a sub-seafloor strength model based on 37 short dynamic and
eight long static piezocone penetration tests, and laboratory experiments on one Calypso piston and 10 gravity cores. Significant
strength variations were detected when comparing measurements from the shelf and the shelf break, with a significant drop...

Provedor de dados: 5
Autores: Schnurle, Philippe; Liu, Char-shine; Lin, Andrew T.; Lin, Saulwood.
A dense seismic reflection survey with up to 250-m line-spacing has been conducted in a 15 × 15 km wide area offshore
southwestern Taiwan where Bottom Simulating Reflector is highly concentrated and geochemical signals for the presence of gas
hydrate are strong. A complex interplay between north–south trending thrust faults and northwest–southeast oblique ramps exists
in this region, leading to the formation of 3 plunging anticlines arranged in a relay pattern. Landward in the slope basin, a
north–south trending diapiric fold, accompanied by bright reflections and numerous diffractions on the seismic profiles, extends
across the entire survey area. This fold is bounded to the west by a minor east-verging back-thrust and assumes a symmetric

Autores: Purvina, S; Béchemin, Christian; Balode, M; Verite, Celine; Arnaud, Christophe; Maestrini, Serge Y.
The use of riverine dissolved organic matter by the heterotrophic bacteria associated with a culture of the cyanobacterium
Microcystis aeruginosa and release of simple nitrogen compounds were studied in an experimental series. Bacteria reduced the
bulk of dissolved organic nitrogen (DON) by half, but when associated with M. aeruginosa, DON was excreted and its
concentration rose by 13%. During the stationary growth phase bacteria released ammonium, doubling the concentration of
ammonia as well as of nitrates. Bacteria associated with M. aeruginosa consumed riverine DON and joined the ammonification
and nitrification process, supplying cyanobacteria with simple nitrogen compounds.

The downstream part of the Loire river is divided into three regulation zones (marine, fluvial and mixed zones) where a traditional
fishery for sea lamprey is practised. More than one hundred professional fishermen (either marine or fluvial statute) are interested
in this activity during winter and spring to catch lampreys on their trip to the up stream spawning areas. The fluvial contraints
(fluvial discharge, tidal current etc...) generate two types of exploitation : the osier trap and the trammel net. For both studied
years 1988 and 1989, total catches are estimated to 37,9 T (88) and 50,2 T (89), indicating the economical value of this fishery,
amounting for 2,6 MF (88) and 3,3 MF (89). This species is dedicated to the market of the Aquitaine region...

The experimental study of marine animal nutrition raises a number of technical issues, especially that of food distribution, when it
is supplied in the form of pellets with a low water content. Hand feeding has different disadvantages. Farmers have indeed to
supply an increasing number (for experimental purposes) of batches, several times per day and at regular intervals, with various
types of food of well-defined quantities. Thus, many hours are dedicated each day to feeding. Moreover, the large number of
interventions implied influences the fishes' behaviour.

First rearing attempts with the european clams Ruditapes decussatus, the pacific clams Ruditapes philippinarum and the clam
Mercenaria mercenaria have been realized by placing the bood into grating cages above the ground. This technic permits a good
survival during the so-called "pre-growth" stage. However, if rearing of juveniles is persued beyond 2 centimeters, growth is
strongly delayed and mortality increases due to valve distortion and shell infection by parasitic worms.

This study is concerned with the development of a tool to predict the long term behaviour of adhesively bonded steel joints aged
in sea water. First, diffusion kinetics and the mechanisms governing the degradation of mechanical properties of an epoxy
adhesive are described. These two sets of data were used in a Coupled finite element (FE) analysis to determine the stress state in
double lap shear (DLS) specimens before and after aging. However, subsequent tests on DLS specimens indicated an adhesive and
not cohesive failure mode, so this approach could not be used to predict failure in the present case without introducing an
interfacial damage parameter. A second approach was therefore employed, in which modified Arcan samples were designed in
order to...

Marine biotoxins are algal metabolites that can accumulate in fish or shellfish and render these foodstuffs unfit for human

methanol and isopropanol were evaluated for their efficiency in extracting toxins from algal biomass. Isopropanol was chosen for
further experiments thanks to a slightly higher recovery and no artifact formation. Comparison of Oasis HLB, Strata-X, BondElut

Monitoring and predicting the biogeochemical state of the ocean and marine ecosystems is an important application of operational
oceanography that needs to be expanded. The accurate depiction of the ocean's physical environment enabled by Global Ocean
Data Assimilation Experiment (GODAE) systems, in both real-time and reanalysis modes, is already valuable for various for
various applications, such as the fishing industry and fisheries management. However, most of these applications require accurate
estimates of both physical and biogeochemical ocean conditions over a wide range of spatial and temporal scales. In this paper, we
discuss recent developments that enable coupling new biogeochemical models and assimilation components with the existing

Autores: Fromentin, Jean-marc; Dauvin, Jean-claude; Ibanez, F; Dewarumez, Jean-marie; Elkaim, B.
This study examines whether meso-scale meteorological events, in particular the alternation of cold and mild periods, influenced
the structure of four Abi cr alba communities, sampled from 1977 to 1992 on the northwest French coast. We propose a new
numerical procedure to describe temporal variations in the structure of each assemblage, using some niche-oriented models
recently developed by Tokeshi (1993). The description of the temporal changes in the structure of each community was
summarized into a 2D-plot of an ordination, performed on observed and simulated patterns. Results showed that important
changes occurred in these four assemblages, which were not directly related to the meso-scale climatic events, but mainly to the
local environmental factors...

Autores: Muresan Paslaru, Bogdan; Cossa, Daniel; Richard, S; Burban, B.
The distribution and speciation of mercury (Hg) in air, rain, and surface waters from the artificial tropical lake of Petit-Saut in
French Guiana were investigated during the 2003/04 period. In the air, total gaseous mercury (TGM) at the dam station averaged
12 +/- 2 pmol m(-3) of which > 98% was gaseous elemental mercury (GEM). GEM distribution depicted a day-night cycling
with high concentrations (up to 15 pmol m(-3)) at dawn and low concentrations (down to 5 pmol m(-3)) at nightfall. Reactive
gaseous mercury (RGM) represented < 1% of the GEM with a mean concentration of 4 3 fmol m(-3). Diel RGM variations
were negatively related to GEM. In the rain, the sum of all Hg species in the unfiltered (HgTUNF) averaged 16 +/- 112 pmol L-1.

This work deals with the development of a high sensibility DNA biosensor based on a 50MHz Quartz Crystal Microbalance
(QCM) Oscillator Electronic Circuit. The designed QCM oscillator sensor is able to detect the presence of complementary DNAs
in a solution that match the sequence on a given strand in function of the changes in the output frequency of the oscillator. The
design is adapted so that the Barkhausen condition is satisfied even when the quartz is immerged in liquid media. Also a
comparative study of the developed 50MHz biosensor in front of a QCM oscillator with smaller frequency is carried out, with
object of checking if the sensibility of the oscillator increases, allowing to detect smaller concentrations of the complementary
DNA.

Extractable manganese in the southeastern East China Sea Shelf and the Okinawa Trough

The distribution of extractable manganese, which is likely to be similar to dissolved manganese, in a transect from the mid-shelf
of the southeastern East China Sea Shelf across the Kuroshio to the Okinawa Trough was determined in May 1991. In the surface
layer above 200 m, the higher concentrations of extractable manganese (5 to 6 nM) are found at the most shoreward station.
Mixing between the shelf water and the Kuroshio results in a tongue of manganese-rich water (> 3 nM) extending from the
shelf into the Okinawa Trough. In contrast, the Kuroshio surface water and the upwelling Kuroshio subsurface water, both with
concentrations of < 3 nM, are manganese-poor. Thus, during upwelling and frontal exchanges, manganese-poor water is
imported into the...

drainage system over the last 130 kyr, by comparing deposited sediments in the sink and the maximum eroded volume in the
source using total denudation proxies. Evaluation of the solid sediments deposited offshore and careful integration of uncertainties
from the age model and physical properties allow us to constrain three periods of sedimentation during the last climatic cycle. The
peak of sedimentation initiated during Marine Isotopic Stage (MIS) 3 (ca. 45 ka) and lasted until late in MIS 2 (ca. 18 ka). This

To gain a better understanding of the fluid–structure interaction and especially when dealing with a flow around an arbitrarily

during the flow measurements. A particularly useful application is the determination of unsteady turbulent flow velocity field
around a moving porous fishing net structure which is of great interest for selectivity and also for the numerical code validation
which needs a realistic database. To do this, a representative piece of fishing net structure is used to investigate both the Turbulent

The annelid Paralvinella grasslei is a deep-sea vent endemic species that colonizes the wall of active chimneys. We report here the
first data on its thermal biology based on in vivo experiments in pressurized aquaria. Our results demonstrate that P. grasslei
survives a 30 min exposure at 30 degrees C, and suggest that the upper thermal limit of this species is slightly above this
temperature. The first signs of stress were noticed at 30 C, such as a significant increase in the animal's activity and the expression
of HSP70 stress proteins. A preliminary investigation of the kinetics of stress protein expression surprisingly showed high levels
of HSP70 proteins as late as 3.5 h after the heat shock. Finally, we provide here the first sequences for vent...

Dissolved and particulate Th-234 activities were determined and phyto- and zooplankton biomass were periodically measured 8
miles off Nice (Mediterranean Sea) during spring 1987. The results show a strong variability of Th-234 distribution on short time
scales in northwestern Mediterranean surface waters. The good correlation observed between the zooplankton biomass and the
rate of Th-234 export to deep water in particulate form is in agreement with the assumption that the residence time of particulate
Th-234 in oceanic surface waters is controlled by zooplankton grazing. Moreover, our results indicate the importance of salps in
particular as efficient removers of small suspended particles in surface waters.

Yellowfin tuna (Thunnus albacares) is a main target for the fisheries at Fish Aggregating Devices (FADs) off the south of
Okinawa island. Catch and weight composition of the tuna were monitored at a fisheries cooperative market from 1989 to 1998.
Some distinct weight groups (considered to represent cohorts) appeared in the catch and the weight of these groups increased
monthly - presumably as individual tuna grew. Although small, light weight fish were caught year-round, the 2 kg weight group
that was recruited in May grew to about 15 kg by May of the next year. There was a significant seasonal cycle in the monthly
catches. The catch of heavier weight groups decreased in winter indicating the tuna moved out of this FAD area. At one of huge

applied in 21 stations subjected to different levels of anthropogenic pressure, along the French Mediterranean coasts. The reefs
were characterized from both the geomorphologic and bionomic (biotic cover, conspicuous species richness, canopy-forming
species, etc.) points of view, and their health status was estimated through the COARSE (COralligenous Assessment by
ReefScape Estimate) index. The sensitivity of the COARSE index and the robustness of the RVA approach to observer biases
were analyzed. Results showed that most coralligenous reefs were characterized by (sub) vertical cliffs or platforms with variable
slope, usually...

Interface air-mer : aspects écologiques du microneuston dans le film de surface
Provedor de dados: 5
Autores: De Souza Lima, Yolanda.
The sea surface microlayer (upper 100 pm) was sampled using Harvey's rotating drum collector. Greater amounts of nutrients,
particulate organic carbon and living material occurred in the surface film than in samples taken at 0,50m. Neuston displayed a
greater level of absolute production, but assimilation numbers were usually lower in the films than at a depth of 0,50m. Algal
phytoplankton also occurred in much higher densities in sea-surface films than in subsurface waters. Individual species
abundances differed between phytoneuston and underlying phytoplankton. Though surface microlayers with a richer nutrient
environment may represent a favorable biotope to microplankton growth, neustonic organisms may be subject to considerable
stress due to higher...

Autores: Thiel, Axel; Michoud, Gregoire; Moalic, Yann; Flament, Didier; Jebbar, Mohamed.
In this study, we developed a gene disruption system for Thermococcus barophilus using simvastatin for positive selection and
5-fluoroorotic acid (5-FOA) for negative selection or counterselection to obtain markerless deletion mutants using single-and
double-crossover events. Disruption plasmids carrying flanking regions of each targeted gene were constructed and introduced by
transformation into wild-type T. barophilus MP cells. Initially, a pyrF deletion mutant was obtained as a starting point for the
construction of further markerless mutants. A deletion of the hisB gene was also constructed in the UBOCC-3256 (Delta pyrF)
background, generating a strain (UBOCC-3260) that was auxotrophic for histidine. A functional pyrF or hisB allele from T.

Eating up the world's food web and the human trophic level
Provedor de dados: 5
Autores: Bonhommeau, Sylvain; Dubroca, Laurent; Le Pape, Olivier; Barde, Julien; Kaplan, David; Chassot, Emmanuel;
Nieblas, Anne-elise.
Trophic levels are critical for synthesizing species' diets, depicting energy pathways, understanding food web dynamics and
ecosystem functioning, and monitoring ecosystem health. Specifically, trophic levels describe the position of species in a food
web, from primary producers to apex predators (range, 1-5). Small differences in trophic level can reflect large differences in diet.
Although trophic levels are among the most basic information collected for animals in ecosystems, a human trophic level (HTL)
has never been defined. Here, we find a global HTL of 2.21, i.e., the trophic level of anchoveta. This value has increased with
time, consistent with the global trend toward diets higher in meat. National HTLs ranging between 2.04 and 2.57 reflect a...

Scampi (Nephrops norvegicus) is traditionally fished with bottom trawls on muddy grounds. Some trawlers from Bayonne fish it
from May to August in the south of the Bay of Biscay. The Capbreton area is partly forbidden to trawling and net fishing (see
appendix 1) In spring and summer, it is frequented by a fleet of about fifteen vessels, among which are some lining vessels,
fishing hake, and a few pot vessels, targeting crabs. Some of these vessels could be interested in using scampi traps in this area in
order to be more versatile and, to a certain extent, to diminish their economical vulnerability through a diversification of the
revenues generated by another high market value species. Ifremer offered to assess a new tool: scampi trap, on the Basque and...

Advances in measuring ocean salinity with an optical sensor

Guillerme, O.
Absolute salinity measurement of seawater has become a key issue in thermodynamic models of the oceans. One of the most
direct ways is to measure the seawater refractive index which is related to density and can therefore be related to the absolute
salinity. Recent advances in high resolution position sensitive devices enable us to take advantage of small beam deviation
measurements using refractometers. This paper assesses the advantages of such technology with respect to the current
state-of-the-art technology. In particular, we present the resolution dependence on refractive index variations and derive the limits
of such a solution for designing seawater sensors well suited for coastal and deep-sea applications. Particular attention has been
paid to...

Autores: Wildish, David; Lassus, Patrick; Martin, Jennifer; Saulnier, Alinne; Bardouil, Michele.
The effects of toxic and non-toxic strains of Alexandrium sp. on the initial feeding responses of the Pacific oyster Crassostrea
gigas were determined by continuous monitoring of the clearance rate of individual oysters. This was determined fluorometrically
by loss of fluorescence of live microalgae introduced as food. Feeding oysters with toxic or non-toxic A. tamarense and toxic A.
fundyense resulted in stop/start clearance behaviour. In contrast, control oysters fed a reference microalga, Isochrysis sp., known
to support their growth, did not exhibit this behavior. Pacific oysters acclimated to Isochrysis sp., fed mixtures of
Alexandrium/Isochrysis, showed further evidence of stop/start clearance. Exposure for periods up to 48 hours with non-toxic A....

Identification and separation of saxitoxins using hydrophilic interaction liquid chromatography

Provedor de dados: 5
Autores: Poyer, Salome; Loutelier-bourhis, Corinne; Coadou, Gael; Mondeguer, Florence; Enche, Julien; Bossee, Anne; Hess,
Philipp; Afonso, Carlos.
The aim of this work was to develop a reliable and efficient analytical method to characterise and differentiate saxitoxin analogues
(STX), including sulphated (gonyautoxins, GTX) and non-sulphated analogues. For this purpose, hydrophilic interaction liquid
chromatography (HILIC) was used to separate sulphated analogues. We also resorted to ion mobility spectrometry to differentiate
the STX analogues because this technique adds a new dimension of separation based on ion gas phase conformation. Positive and
negative ionisation modes were used for gonyautoxins while positive ionisation mode was used for non-sulphated analogues.
Subsequently, the coupling of these three complementary techniques, HILIC-IM-MS, permitted the separation and identification
of STX...

Intensifying Weathering and Land Use in Iron Age Central Africa
Provedor de dados: 5
Autores: Bayon, Germain; Dennielou, Bernard; Etoubleau, Joel; Ponzevera, Emmanuel; Toucanne, Samuel; Bermell, Sylvain.
About 3000 years ago, a major vegetation change occurred in Central Africa, when rainforest trees were abruptly replaced by
savannas. The consensus is that the forest disturbance was caused by climate change. We show here that chemical weathering in
Central Africa, reconstructed from geochemical analyses of a marine sediment core, intensified abruptly at the same period,
departing significantly from the long-term weathering fluctuations related to the Late Quaternary climate. Evidence that this
weathering event was also contemporaneous with the migration of Bantu-speaking farmers across Central Africa suggests that
human land-use intensification at that time already had a significant impact on the rainforest.

A state-space model to derive bluefin tuna movement and habitat from archival tags
Provedor de dados: 5
Autores: Royer, Francois; Fromentin, Jean-marc; Gaspar, P.
Archival tagging provides a unique way to study the spatial dynamics and habitat of pelagic fish. This technique generates
lagrangian data of a particular type in marine ecology: although highly informative about processes at different scales (e.g.
horizontal movements versus diving behaviour), such data are impaired by location errors and the lack of combination with actual
environmental variability. The present paper introduces a framework for modelling bluefin tuna movement in relation to its
habitat, using records of light, depth and temperature from archival tags. Based on data assimilation concepts and methods, we
show how an explicit formulation of the observation process and the statistics of external variables (e.g. ambient temperature)

Retention efficiency in oyster Crassostrea gigas exposed to variable food quantity and quality

Autores: Barille, Laurent; Prou, Jean; Heral, Maurice; Bougrier, Serge.
Relative retention efficiency (Er%) of Crassostrea gigas was estimated in the laboratory with 7 diets consisting of algae and silt.
Total particulates varied from 1.34 mg/l in natural sea water to 27.65 mg/l in natural sea water enriched with silt. It was also
calculated from field experiment to get high concentration of seston up to 66 mg/l. It appeared that Crassostrea gigas did not
adjust its retention according to the food quality and the gill porosity was controlled by the concentration of particulate matter. In
low seston load (1.34 mg/l) the oyster showed no change in retention for particles larger than 3-4 µm (Equivalent Spherical
Diameter, ESD) but at the highest concentration (66 mg/l) it could only retain with a maximum efficiency particles...

Sound waves are the only practical means of remote investigation and transmission in seawater. All along the XXth century,
underwater acoustics became one of the major technologies used for exploration and exploitation of the oceans for scientific,
industrial, or military purposes. It is nowadays able to play, inside the oceans, the roles devoted to radio and radar in atmosphere
and space, and is widely employed in the fields of navigation, fisheries, defence, oceanography and ocean engineering. This book
presents, in a clear and concise way, the basic physical phenomena governing underwater acoustical waves, the general features of
sonar systems, and an overview of their applications.

Global change and its associated temperature increase has directly or indirectly changed the distributions of hosts and pathogens,
and has affected host immunity, pathogen virulence and growth rates. This has resulted in increased disease in natural plant and
animal populations worldwide, including scleractinian corals. While the effects of temperature increase on immunity and
pathogen virulence have been clearly identified, their interaction, synergy and relative weight during pathogenesis remain poorly

The Indian Ocean is unique among the three tropical ocean basins in that it is blocked at 25 degrees N by the Asian landmass.
Seasonal heating and cooling of the land sets the stage for dramatic monsoon wind reversals, strong ocean atmosphere
interactions, and intense seasonal rains over the Indian subcontinent, Southeast Asia, East Africa, and Australia. Recurrence of
these monsoon rains is critical to agricultural production that supports a third of the world's population. The Indian Ocean also
remotely influences the evolution of El Nino-Southern Oscillation (ENSO), the North Atlantic Oscillation (NAO), North
American weather, and hurricane activity. Despite its importance in the regional and global climate system though, the Indian
Ocean is the most...

A travers le projet européen PECOSUDE (n° 99/024) signé en 2000 pour 2 ans, les trois pays participants, la France, l’Espagne et
le Portugal ont eu pour objectif de décrire les caractéristiques des petites pêches côtières et estuariennes de la côte atlantique du
Sud de l’Europe (de la Loire au Portugal). Ce travail s’est basé sur un bilan des flottilles côtières, du point de vue des typologies,
de l’aspect économique et social de l’activité et de la commercialisation des produits issus de cette pêche. La compréhension des
systèmes d’exploitation impose l’utilisation conjointe des connaissances de l’halieutique (données 1999), de l’environnement, de

Etude Sédimentaire Appliquée à l'Aquaculture pour Cinq Estrans de Bretagne Sud (Morbihan et
Loire Atlantique).
Provedor de dados: 5
Autores: Lemoine, Gérard.
Within the national molluscan monitoring network, a sedimentary study was carried out on five experimental sites located in
southern Brittany (i.e., from Etel to Pen-Bé rivers). The study aimed to specify sediment integrating characteristics with regards to
hydrobiological variables. Moreover, interactions between sediment and water column characteristics were specified. It appears
that this approach is likely unappropriate to characterize interdical rearing area productivity. However, this approach can support
the site evaluation on a long term basis to sustain shellfish culture management. This would require additional study to assess
sediment reactivity to abnormal events like drastic salinity decrease.

Risques en aquaculture et implications pour un système d'assurance : éléments de réflexion
Provedor de dados: 5
Autores: Antona, Martine; Paquotte, Philippe.
Les expériences en matière d"assurance des entreprises de cultures marines se sont développées dans la décennie 70. Elles se sont
caractérisées par une couverture très large du risque avec des taux de prime importants qui ont restreint le champs des assurés et
par une couverture géographique très faible. Dans la pratique, seuls les ostréiculteurs de Bretagne Nord ont été assurés. L"arrêt
brutal de ces expériences à la fin des années 70 est dû au retrait des assureurs après I"épizootie de l'huître plate. La mise en place
de systèmes d"assurance en aquaculture nouvelle à la fin des années 80 et leur réexamen actuel pour la conchyliculture ont été
favorisés par plusieurs facteurs : - le développement des productions aquacoles sur incitation publique, - la...

The inability to rear the oysters C. gigas and O. edulis in certain Brittany waters has prompted us to conduct breeding trials with
C. angulata C. gigas and their hybrids. Results have revealed that all the strains tested were sensitive to Tributyl tin (TBT),
showing atnormal shell thickness and their growth was lower than C. gigas. In addition, C. angulata was still affected by the
presence of the Iridovirus in France.

The European flat oyster Ostrea edulis has been considered as the traditional French oyster for a very long time and has now
nearly disappeared from our farms, as a consequence of the two successive epizootic of the Marteilia refringens parasite and
Bonamia ostreae. The actual quasi monoculture of Crassostrea gigas has made necessary the search for a diversification in oyster
culture, including the search for a new start of the indigenous flat oyster culture. The Ifremer has been conducting parallel works
since 1985 in order to better understand the biology of the parasite as well as to try and select different lines of flat oyster resistant
to Bonamia ostreae.

In the context of the European Water Framework Directive (WFD), monitoring programs and related indicators have been
developed to assess anthropogenic impacts on various components of aquatic ecosystems. While great precautions are usually
taken when selecting and calculating relevant core metrics, little attention is generally paid to the generation of the multimetric
indicator, i.e. the combination of the different core metrics. Indeed, most multimetric indicators are generated by simply averaging
or summing metrics, without taking into account their sensitivity and their variability. Moreover, few indicators provide a rigorous
estimate of the uncertainty of the assessments, while this estimation is essential for managers. In this context, we developed a...

Histamine fish poisoning is common and due to toxic concentrations of histamine often produced by Gram-negative bacteria in
fin-fish products with a high content of the free amino acid histidine. The genus Morganella includes two species previously
reported to cause incidents of histamine fish poisoning. Morganella morganii and Morganella psychrotolerans are both strong
producer of histamine. However, little is known about the occurrence and critical stages for fish contamination with these bacteria.
To elucidate contamination routes of Morganella, specific real-time quantitative PCR (RTi qPCR) methods for quantification of
M. morganii and M. psychrotolerans have been developed. Selective primers amplified a 110 bp region of the vasD gene for M....

The release of polycyclic aromatic hydrocarbons (PAHs) into the environment has increased very substantially over the last
decades. PAHs are hydrophobic molecules which can accumulate in high concentrations in sediments acting then as major
secondary sources. Fish contamination can occur through contact or residence nearby sediments or though dietary exposure. In
this study, we analyzed certain physiological traits in unexposed fish (F1) issued from parents (F0) exposed through diet to three
PAH mixtures at similar and environmentally relevant concentrations but differing in their compositions. For each mixture, no
morphological differences were observed between concentrations. An increase in locomotor activity was observed in larvae issued

Results are presented on recent investigations about the paleoenvironmental signification of Mesozoic and Cenozoic clay
successions, recovered in marginal areas of Atlantic and North-West Pacific Oceans and in the Mediterranean Sea. Chiefly
derived from adjacent land-masses, clay assemblages represent useful indicators of major tectonical, climatical, hydrodynamical
and morphological events which occurred through time. Examples are chosen in different sedimentary basins, and at different
geological periods from late Jurassic to late Quaternary. Results are compared with previous work, in order to emphasize the

Synthetic mooring ropes for marine renewable energy applications

Synthetic mooring ropes have a proven track record of use in harsh operating conditions over the past two decades. As one of the
main users of ropes for permanent mooring systems, the oil and gas industry has opted for these components because they possess
performance characteristics and economies of scale which are in many respects superior to steel components. Given this accrued
experience, it is unsurprising that several marine renewable energy (MRE) device developers have utilised synthetic ropes,
motivated by the need to specify economical, reliable and durable mooring systems. Whilst these components are potentially an
enabling technology for the MRE sector, this is a new field of application which can feature highly dynamic mooring tensions

practices in the traditional oyster production region of Marennes-Oleron (France). Four oyster rearing conditions, varying culture
location ("on-" or "off-bottom"), and site depth (65% to 80% daily immersion termed "deep" or 45% to 65%, termed "shallow")
were studied to compare biologic performance and maturation status of oysters, in relation to sediment and water column
parameters. The most severe mortality occurred in June to July in "on-bottom" reared oysters (25%), as compared with 10%
mortality in "off-bottom" cultured oysters. Oysters (shell and meat) grew significantly better when reared "off-bottom" than
"on-bottom."...

The aim of this work was to investigate the catabolic process of three kinds of dietary carbohydrates in the gut of sea bass
juveniles, with the possible contribution of the intestinal microbiota to the nutrition of the host, and the subsequent effects on
intermediary metabolism. A first diet contained waxy maize (99% amylopectin), a highly digestible form of starch. A second diet
was less quickly digestible due to its high amylose content of resistant starch. Two other diets contained fibre instead of starch,
either only cellulose as control, or also other non-starch polysaccharides brought by lupin meal. The effect of the diets on the host
confirmed previous results, with the stimulation of glucose storage in the liver in sea bass fed the starchy diets,...

Multiannual management plans SWW and NWW ( STECF - 15 - 08 )
Provedor de dados: 5
Autores: STECF (Scientific, Technical and Economic Committee for Fisheries).
The STECF was tasked with an analysis of the likely effects of proposed management plans for the Southwestern (Bay of Biscay
and Iberia) and Northwestern (Celtic sea) waters. Quantitative analyses were carried out to compare the likely effect of those
management plans and of the direct application of the CFP on both stocks and fleets involved in these fisheries. Based on the
results of simulations of the provisions of the proposed management plans, STECF concluded that, setting fishing opportunities in
line with single-species FMSY ranges will provide managers with additional flexibility compared to the basic provisions of the
2013 CFP. Such flexibility is likely to help alleviate the problem of mismatches in quota availability in mixed-species fisheries...

Relationships between benthic macrofauna and habitat suitability for juvenile common sole (Solea
solea, L.) in the Vilaine estuary (Bay of Biscay, France) nursery ground
Provedor de dados: 5

Coastal and estuarine systems are among the most threatened by human activities which damage their ecological function and, in
particular, their nursery role for many marine species. In this context, the protection of these vital ecosystems is a critical issue for
the management of fisheries resources. To that aim, functional approaches have to be developed that make it possible to assess
habitat suitability and quality. The common sole, Solea solea (L.) was selected as an indicator species to identify the features of
coastal and estuarine nursery habitats in the Bay of Biscay (France).
Previous studies have shown that young-of-the-year (YOY)
sole are strongly dependent upon various abiotic factors, and especially bathymetry, sediment cover and the...

Marine atmospheric boundary layer over some Southern Ocean fronts during the IPY BGH 2008
cruise
Provedor de dados: 5
Autores: Messager, Christophe; Speich, Sabrina; Key, E.
A set of meteorological instruments was added to an oceanographic cruise crossing the Southern Ocean from Cape Town to 57
degrees 33' S during the summer of 2008. The Cape Cauldron, the Subtropical, Subantarctic, Polar and southern Antarctic
Circumpolar current fronts were successively crossed. The recorded data permitted to derive the exchange of momentum, heat and
water vapour at the ocean-atmosphere interface. A set of 38 radiosonde releases complemented the dataset. The marine
atmospheric boundary layer characteristics and air-sea interaction when the ship crossed the fronts and eddies are discussed. The
specific role of the atmospheric synoptic systems advection on the air-sea interaction over these regions is highlighted.
Additionally, the...

Estimation des paramètres biologiques de l'empereur (Hoplostehus atlanticus et du grenadier
(Coryphaenoides rupestris)
Provedor de dados: 5
L'empereur (Hoplostethus atlanticus) et le grenadier de roche (Coryphaenoides rupestris) sont des espèces exploitées
systématiquement depuis 1990 par les flottilles de la pêche industrielle et semi-industrielle française dont elles représentent
aujourd'hui une part notable des apports. Cette mise en exploitation de ressources délaissées ou méconnues par le passé, a amené
rapidement les gestionnaires à se poser le problème de l'importance de leur disponibilité et de leur pérennité. La présente étude
constitue une étape préliminaire destinée à présenter les premières acquisitions concernant les paramètres biologiques et
dynamiques de ces deux espèces. Ces ressources sont exploitées à l'ouest des îles britanniques, en Mer Celtique et dans le Golfe
de Gascogne...

La baie de Bourgneuf est un bassin de 34000 ha dont l'activité ostréicole représente à elleseule plus de 95% du chiffre d'affaire
local réalisé par la production conchylicole. Lesdifférentes études qui ont été réalisées ont montré que le stock d'huîtres en élevage
(40000t) et la production annuelle (13000 t) qui en est issue variaient peu au cours des années (Barillé-Boyer et al., 1997, Haure et
al. , 2003). Toutefois, les performances de croissance, ainsi que la qualité des huîtres produites sont médiocres et place ce bassin
au dernier rang des sites français de production (données du réseau REMORA). Plusieurs études ont été entreprises, pour
expliquer ce phénomène, par l'approche de la capacité trophique de cet écosystème et l'estimation des biomasses...

The primary pathogens related to shellfishborne gastroenteritis outbreaks are noroviruses. These viruses show persistence in
oysters, which suggests an active mechanism of virus concentration. We investigated whether Norwalk virus or viruslike particles
bind specifically to oyster tissues after bioaccumulation or addition to tissue sections. Since noroviruses attach to carbohydrates of
the histo-blood group family, tests using immunohistochemical analysis were performed to evaluate specific binding of virus or
viruslike particles to oyster tissues through these ligands. Viral particles bind specifically to digestive ducts (midgut, main and
secondary ducts, and tubules) by carbohydrate structures with a terminal N-acetylgalactosamine residue in an alpha...

The Arctic Ocean is a fundamental node in the global hydrological cycle and the ocean's thermohaline circulation. We here assess
the system's key functions and processes: 1) the delivery of fresh and low salinity waters to the Arctic Ocean by river inflow, net
precipitation, distillation during the freeze/thaw cycle and Pacific Ocean inflows; 2) the disposition (e.g. sources, pathways and
storage) of freshwater c
