| New Caledonian shrimp farming feasibility studies started in the mid-seventies. Today ca. 2000 tons of Litopenaeus stylirostris, introduced in 1978, are semi-intensively produced each year. Since fifteen years, production has been impacted by two seasonal vibriosis, the “Summer” syndrome caused by Vibrio nigripulchritudo in relation to pond bottom and water column quality, and the “Winter Syndrome” caused by Vibrio penaeicida in relation to drastic temperature drops . With the ambition of elucidating processes possibly leading to mortality outbreaks in ponds, Ifremer has been conducting a research program since 2003 under the DESANS project (2003-2006) and the present DEDUCTION project, equally funded by the South and North Provinces and by the Government... |

| Shrimp farming in New Caledonia relies on the culture of a domesticated strain of Litopenaeus stylirostris introduced from Mexico at a time when genetic principles were of little or no consideration. Since then, advances in agriculture and for some aquatic species of importance led caledonian shrimp farmers to reconsider the appropriateness of a genetic improvement strategy adapted to local biotechnical and economical constraints. This questioning involves many different and interrelated aspects: scientific and technologic (genetics, biosecurity, quarantine, ), economic and organizational (financing, diffusion of genetic improvement) and pedagogic (awareness of farmers). Local institutions, producers associations, research centre and sanitary services... |

| The present article introduces and defines what are the rogue or freak waves. After an historical reminder on the recent consideration of their existence, several events of waves having struck big or small ships or still the coastline are presented. A paragraph is dedicated to the scientific explanation of the phenomenon and the difference with other phenomenons such tsunamis or tidal bores is clarified. After a reminder of the international mobilization towards a forecast system, a conclusion focuses on events met in New Caledonian waters and analyzes more exactly testimonies related to this type of phenomenon by trying to clarify their causes. |

| The file on New Caledonia and « Blue Gold » presents a set of issues deemed relevant to the “marine Caledonia as a fact” and points out assets to and stakes for the country. Features taken into consideration are natural, geographic, physical, environmental in nature, particularly regarding the biodiversity existing in shores, lagoons and reefs, and the wide expanse of sea and oceans constituting interior waters and Caledonian EEZ. Historical aspects of the country and its links with the sea are also developed, as well as the wealth of past maritime history which has been written and will continue to be. With respect to current global trends towards the role of sea and ocean for the future of our planet, and as far as new growth models are concerned, the... |

| Bathymetric estimation using remote sensing images has previously been applied to high spatial resolution imagery such as CASI, Ikonos, or SPOT but not on medium spatial resolution images (i.e., MERIS). This choice can be justified when there is a need to map the bathymetry on large areas. In this letter, we present the results of the bathymetry estimation over a large known area, the Gulf of Lion (France), expanding over 270 x 180 km. |

| The SYSCOLAG programme is a pilot operation at national level for experimenting with a knowledge-pooling system applied to the field of integrated coastal area management (ICAM). SYSCOLAG aims to constitute an interface between 'knowledge' and the users of knowledge' on questions related to the conservation and the development of the coastal zone of the Languedoc-Roussillon. To that end, SYSCOLAG offers both a transdisciplinary approach associating life sciences, earth sciences, social and informatic sciences and multistakeholders approach (associating scientists, decision-makers, professional users of the sea, environmental protection associations, and the general public) to integrated management of the coastal zone of the Languedoc-Roussillon. The system... |

| This text which deals with the potential of the marine bacteria articulates around six chapters. The first one offers general points of view on marine wealth. The second gives a typology of the various valuations of the living matter in the form of biotechnologies. The third specifies the meaning of the marine or blue biotechnologies and places the part occupied by bacteria. The fourth describes several ways fur valuating bacteria and their by products (biopolymers as EPS and PHA) and applications and offer a digression on medicine coming from the sea. The fifth chapter is interested in the atypical environments and the particular conditions they offer. The sixth is dedicated to the New-Caledonian case, its natural specificities and introduces the case of... |

| This text is the first part of an article focused on the scientific approaches in building forward-looking studies. After some basic definitions and historical reminders and examples, this text calls back the needs to anticipate the change. It specifies this need with some keywords on what the forward-looking analysis can offer by underlining that the sea and its values are exactly a fundamental support there…. It completes these elements by philosophic definitions of the prospective. It clarifies too that the scientific analysis can help to build a forward-looking reflexion on the basis of three foundations. |

| After a reminder on the program SYSCOLAG (Coastal and Lagoons Systems), of the regulatory and legislative context in territorial economic planning on the coast, we describe the structure of the developed methodological tool. We clarify then the method according to its three main trunk roads: effects of the activities and uses on the economy of the territory, the effects of the activities and uses on the natural environment and the living environment, the evaluation of the interactions between activities and uses. We apply the method exposed in a frame demonstrator by taking the scenario of the lagoon and coastal territory of the Thau Basin (Hérault). A set of appendices, including in particular evaluation grids are supplied with support for the... |

He calls back what is remote sensing, its two main types : passive and active remote sensing and clarify the usable portions of the electromagnetic spectre to characterize the phenomena that affect the surface or shallows of the sea and the ocean. Then this text reviews these various usable portions of the spectre and specifies the various behaviors of the marine and maritime targets. Are so reviewed: a) the domain of the visible and of the near-infrared and the applications regarding bathymetry, characterization of shallow bottoms or the color of the sea; b) the domain of thermal infrared and application... |
