| This project is a contribution to the improvement and development of passive sampling techniques. The objectives are: - to develop ways to limit the fouling formation on the samplers requiring prolonged immersion time (POCIS) and ensure a "constant" and reproducible sampling rate - test and validate the DGT developed specifically for Hg wich is a "WFD priority" metal. Key words (thematic and geographical area) :Passive samplers, POCIS, DGT, fouling, sampling rate, Hg, baie du Lazaret , étang de Thau |

| Salinity is the essential parameter for ocean dynamics studies. Its definition and using in the equations used to calculate the thermodynamic properties of seawater, were revised in 2010, opening the possibility of new sensors developments. In this context, NOSS (NKE Optical Salinity Sensor) has emerged as one of the first underwater instrument for in situ refractive index measurement in the past years open up the scope of possibilities to access to density parameter. This achievement is the fruit of the cooperation between several institutions and the fruit of several years of developments and trials. NOSS sensor is designed to be deployed in coastal environment and open-ocean waters up to 2000m, especially on profiling floats of the Argo network. |

| La validité du concept de station de mesure haute-fréquence Marel a été vérifié par le déploiement d’un réseau constitué de stations de type axisymétrique (Réseau Baie de Seine, Bouée Iroise en rade de Brest). Le mouillage et le comportement de ces bouées en terme d’accessibilité et de maintenance est un handicap pour l’extension vers les zones plus exposées du large. La bouée MOLIT (Mer Ouverte LITtorale) constitue une réponse technique et financière. |

| MarsiteCruise was undertaken in October/November 2014 in the Sea of Marmara to gain detailed insight into the fate of fluids migrating within the sedimentary column and partially released into the water column. The overall objective of the project was to achieve a more global understanding of cold-seep dynamics in the context of a major active strike-slip fault. Five remotely operated vehicle (ROV) dives were performed at selected areas along the North Anatolian Fault and inherited faults. To efficiently detect, select and sample the gas seeps, we applied an original procedure. It combines sequentially (1) the acquisition of ship-borne multibeam acoustic data from the water column prior to each dive to detect gas emission sites and to design the tracks of... |
