| Recently the ANTARES Neutrino telescope's Infrastructure in the deep Mediterranean Sea, has been extended by a Secondary Junction Box. The main emphasis has been to provide basic power and communications capability for new scientific cabled observatories. This new infrastructure provides unprecedented amounts of power and two-way bandwidth to access and control instrument networks in the oceans. This new development allows cabled observatory to connect the seafloor to the Internet via real-time, two-way highspeed communications. This design gives researchers new capabilities beyond the reach of traditional oceanography. Ocean scientists can run deep-water experiments from labs and universities anywhere around the world. Three different underwater... |

| Deep Sea Net is a new concept of deep sea sensor network built from fiber optic micro cable and battery operated IP access nodes. Deep Sea Net fiber optic transport segments are deployed directly from a standard ROV, avoiding the use of a costly cable layer ship. Deployment skid is abandoned on user site ready to connect local sensors and next transport segment. Deep Sea Net is a low consumption network which can be waked on user (or sensor) demand. Lithium batteries and fine power management will give 10 years of autonomy with ¼ of hour operation per day. The innovative approach of Deep Sea Net will permit to build, extend and maintain future sensor networks at very competitive prices. |

| During the past 10 years, large developments and improvements on the technical possibilities and operational availability of full-size, Class III deep ocean work ROVs took place (> 3000 m). This is especially true for the marine science community. Where in the early 90’s scientific ROVs for ultradeep operations were a true technical challenge for technology leading institutions like IFREMER, MBARI, WHOI, and JAMSTEC, the sub-sea technology driving offshore oil and gas industry was orientated almost solely into developments for the shallow water production business. This relation changed dramatically with the achieved breakthroughs in ROV technology, some major of them developed by science institutions, and was adapted quickly into the 3000 m depth range... |

| The general objective of EXOCET/D is to develop, implement and test specific instruments aimed at exploring, describing, quantifying and monitoring biodiversity in deep-sea fragmented habitats as well as at identifying links between community structure and environmental dynamics. Onboard experimental devices will complement the approach, enabling experiments on species physiology. The EXOCET/D working fields include: video and acoustic imagery, in situ analysis of physico-chemical factors, quantitative sampling of macroand micro-organisms, in vivo experiments, integration of multidisciplinary data, implementation on European deep-submersibles and a final phase of technical and scientific validation |

| This paper reports on the status and design of the operational remotely operated vehicle Victor 6000, rated for 6000 m depth and of the 3000 m depth autonomous underwater vehicle Asterxx operated by Ifremer the French Institute for Sea Exploitation. Victor 6000 is part of a global system built of subsystems, scientific modules, winch and cable, dead weight and umbilical, positioning subsystem using acoustic ultra short base line (USBL) techniques, and software for data and dive management. In 2005 the system was equipped with a second toolsled dedicated to high resolution mapping of the sea bed, with both acoustical and optical devices. Asterxx, the first autonomous underwater vehicle (AUV) developed by IFREMER, is 4.5 m in length with a diameter of 0.69... |

| Depuis bien des années ce sont de "merveilleux fous plongeants et leurs drôles de machines" qui ont assuré la découverte du milieu sous-marin. Pour repousser sans cesse les barrières, il a fallu isoler de plus en plus l'homme du milieu au détriment du contact physique, voire charnel, avec ce dernier. |

| The use of autonomous underwater systems, such as AUV, is currently limited by their on board energy supply. The emergence of a higher capacity power source could be a breakthrough that extends these technologies field of application. Since 2005, within the PACSM project1, fuel cell systems for underwater applications were studied. HELION, an AREVA Renewable subsidiary, dedicated to both PEM fuel cell and electrolyze systems development, has designed a fuel cell system adapted for AUV energy supply, for integration on IFREMER survey AUV, called IDEFX. This technology interest for underwater power source has already been proven by several experiments. For example, the URASHIMA propelled by a fuel cell system, performed 317 km longdistance continuous nonstop... |

| full-scale mechanical prototype line was deployed to a depth of 2500 m to test the leak tightness of the electronics containers and the pressure-resistant properties of an electromechanical cable under evaluation for use in the ANTARES deep-sea neutrino telescope. During a month-long immersion study, line parameter data were taken using miniature autonomous data loggers and shore-based optical time domain reflectometry. Details of the mechanical prototype line, the electromechanical cable and data acquisition are presented. Data taken during the immersion study revealed deficiencies in the pressure resistance of the electromechanical cable terminations at the entry points to the electronics containers. The improvements to the termination, which have been... |

| Because of its ability of providing very high data transmission rates over distances up to several tens of meters, underwater wireless optical communication (UWOC) has attracted considerable interest during the past few years. The underwater channel is a challenging environment, especially because of its high attenuation. The difficulty of precise localization underwater also leads to unavoidable link misalignments that can have an important impact on the link availability and otherwise on the quality of signal transmission. In this paper, after a review of the recent research works on UWOC and the available commercialized systems, we present the performance study of a typical UWOC system under some simplifying assumptions for system modeling. We also... |
