In order to be able to use all the marine sensors currently available in the market, a new module has to be built to implement the smart sensor standard IEEE-1451 as well as other services used in marine measurements. The smart module is aimed to be used in ALL observatory configurations: autonomous, cabled and buoy-based observatories. This module can also be used for low power data acquisition and control applications in new instrument design such as Ocean Bottom Seismometers (OBS) or any other instrument where data logging, clock synchronization, and plug and play capabilities are important. Therefore, the power consumption of the smart module has to be minimized for batteries based observatories and autonomous instruments. |

The anthropogenic greenhouse effect and the associated temperature rise of the planet represent the main challenging issue for the Earth sciences of the next century. Marine ecosystems are a key component of the Earth system, as they modulate the transfer of greenhouse gases (mainly CO2) to the ocean surface. Moreover, oceanic ecosystems mitigate the effects of anthropogenic carbon injection into the atmosphere, via the so-called “biological pump”. Ocean biogeochemistry is hence confronted to a major challenge: the determination of the extent and efficiency of the climatic feedback of the carbon “biological pump” within the context of climate change. A new type of float, the “ProvBio”, has been developed jointly by Ifremer and the French company KANNAD,... |

New requirements have appeared in the last few years for profiling floats and the ARVOR float is being made to meet these new requests. The two main requirements are less surface time and the ability to modify mission parameters after deployment to monitor specific events.. As a solution, the Arvor has been fitted with Iridium and Argos-3 |

The scientific community observes the ocean for applications in the fields of oceanography and climate research. In order to recover in situ data, more than 3,000 profiling floats are operated in the framework of the Argo Program. Each float performs cycles between the sea surface and a depth of 2,000 meters. Scientific data are gathered while the float is travelling upward from the depths of the oceans, and are then transmitted via a satellite communication system at the end of each cycle. During its time at the surface, mainly dedicated to transmissions, the float is vulnerable and subject to drift, which limits its use in many studies. Moreover, transmission times are becoming longer due to a trend towards high resolution or multi-sensor profiles.... |

In the last ten years, a productive collaboration has grown between the Laboratoire d’Océanographie de Villefranche (LOV), NKE and IFREMER to implement biogeochemical sensors on profiling floats. A first project (2003) was dedicated to the design of the so-called ProvBio floats (models A and B) that consisted of a PROVOR-CTS3 float instrumented with three new optical sensors: a Wetlabs transmissometer (C-Rover), a 3-wavelength Satlantic radiometer (OCR-503) and an “ECO3” Wetlabs sensor, measuring chlorophyll-a fluorescence, colored dissolved organic matter and particle backscattering coefficients (see First Success of ProvBio floats, Coriolis Letter n°5). Then, the integration of biogeochemical sensors continued in the framework of ProNuts project (2009,... |

La mise en œuvre de grands projets maritimes est un exercice complexe du fait de la diversité des acteurs et de leurs enjeux. La volonté d’implication de la société civile nécessite par ailleurs un changement de philosophie dans leur déploiement. L’acceptabilité de ces projets sera induite par un partage de valeurs communes, qui est l’affaire de tous les acteurs dans une démarche de co-construction. Les très fortes disparités entre pays (y compris au sein de l’Union Européenne) sur la question de l’acceptabilité et des enjeux des projets maritimes nous ont conduit à limiter le périmètre de l’étude au domaine maritime français. Nous avons par ailleurs fait le choix de ne pas traiter ici de l’aspect réglementaire des projets, mais plutôt de nous concentrer... |
