| The application of the new Water Framework Directive (WFD) of the European Union will require a dense and frequent monitoring of chlorophyll-a near the coast. Not counting the transitional water bodies located in the vicinity of estuaries, not less than seventy four coastal water bodies have to be monitored along the coast of the French Atlantic continental shelf and the English Channel. All the available data have to be gathered to implement a comprehensive monitoring scheme. To this purpose, we evaluate the capacity of ocean colour imagery to complete the conventional in situ data set collected in coastal networks. Satellite-derived chlorophyll-a concentration is obtained by the application of a coastal Look-Up-Table to water-leaving radiance of the... |

| Based on a combined internet and mail survey in Germany the independence of indicators of trust in public authorities from indicators of attitudes toward genetically modified food is tested. Despite evidence of a link between trust indicators on the one hand and evaluation of benefits and perceived likelihoods of risks, correlation with other factors is found to be moderate on average. But the trust indicators exhibit only a moderate relation with the respondents' preference for either sole public control or a cooperation of public and private bodies in the monitoring of GM food distribution. Instead, age and location in either the New or the Old Lander are found to be significantly related with such preferences. |

| Le projet de développement d'un réseau instrumenté de surveillance de l'environnement littoral correspond à une nécessité d'observations, sur de longues séries temporelles, et de mesures à des fréquences élevées. Il est le résultat d'une analyse des besoins des différents types d'utilisations. Il est l'occasion de coopération entre des scientifiques et des industriels pour développer un réseau de stations instrumentées multiparamètres transmettant les données par satellite vers une station de traitement des données et de diffusion de celles-ci par réseau informatisé. |

| Underwater video techniques are increasingly used in marine ecology studies. Technological progress regarding video cameras, sensors (such as sounders), battery life and information storage make these techniques now accessible to a majority of users. However, diver-based underwater visual censuses, and catch and effort data, remain the most commonly used for observing coastal biodiversity and species. In this paper, we review the underwater video techniques that have been developed since the 1950s to investigate and/or monitor coastal biodiversity. Techniques such as remote underwater video, whether baited or not, diver-operated video and towed video are described, along with corresponding applications in the field. We then analyse the complementary of... |

| Les possibilités d'utilisation d'échantillonneurs passifs pour l'évaluation de la contamination chimique des masses d'eau ont été testées dans le cadre du projet PEPS. L'objectif principal était d'évaluer à "grande échelle" et dans différentes conditions de terrain (20 masses d'eau côtières réparties sur l’ensemble de la façade méditerranéenne française) l'opérationnalité de ces systèmes en terme de réduction des coûts, fiabilité et rapidité d'obtention des résultats, mais aussi en terme de facilité de mise en oeuvre (par du personnel non spécialisé, mais préalablement formé). |

| ABSTRACT: This study validated the use of leaf 17 on the sampling of Opsiphanes invirae Hübner (Lepidoptera: Nymphalidae) through the quantification of caterpillar abundance on the different spirals leaves, in comparison to leaf 17, and, on the apical, intermediate and basal leaf regions. This study was performed in the state of Pará, between March-2014 and March-2015. Results confirmed that leaf 17 is the most adequate method for monitoring this defoliator pest. |

| The impact of the main parameters of water quality which act on the life history of molluscs are presented. Two types of parameters are examined: the first are the physical-chemical parameters as temperature, salinity, turbidity, oxygen concentrations. They can be modified by perturbations directly related to human activities such as management of physical operations, e.g. constructions of dams, dredging for channels or for extraction of materials. Particular attention is given to inputs of nutrients with as consequences eutrophication and depletion of oxygen causing anoxie conditions. Attention will he focussed on some phytoplankton species like Gyrodinium aurelum which can cause mortalities in mollusc shellfish. The action of the main pollutants... |

| Luminous dinoflagellates biomass seasonal dynamics as well as bioluminescence field vertical structure changeability during the year cycle (2008–2009) near the Sevastopol was studied. Two evident peaks during the cold (February) and warm (July–August) periods were revealed, which was connected with differences in development level and phytoplankton vertical distribution, which were stipulated in turn, by water hydrostructure peculiarities in the natural stratification layers. “Winter” bioluminescence maximum in the surface layer was stipulated by the development of C. fusus; P. divergens; P. oblongum mainly, with the cells volume, maximal in the year. The second one, located in the thermocline layer and lower, was formed, mainly, at the expense of C. fusus... |
