Obduction et collision : exemples de la Nouvelle-Calédonie et de la zone de subduction des Nouvelles-Hébrides

Cette thèse présente deux cas particuliers d'évolution de la lithosphère océanique aux frontières de plaques. La première partie concerne l'étude géophysique de la zone d'enracinement de la nappe ophiolitique en Nouvelle-Calédonie. Cette pa...

Communautés biologiques et habitats coralliens de la Corne Sud - Etat initial

La province Sud de la Nouvelle-Calédonie a engagé une étude de l'état initial des communautés biologiques coralliennes et de l'habitat de la Corne Sud dans le cadre de la demande d'inscription des récifs coralliens de la Nouvelle-Calédonie au ...

L'énergie thermique des mers

Ocean Thermal Energy Conversion, OTEC, is a concentrated renewable source of energy available in the one third of the world's ocean lying in the tropics. An OTEC plant is a heat engine fed with warm surface water and cold water pumped up from the dee...

Systèmes halieutiques et DCP dans l'océan Indien: une revue de la diversité des trajectoires et des résultats en termes d'intégration et de durab...

The first fad's in the islands of the South West Indian Ocean were moored in the fifties. The area under study forms part of the Indian Ocean Commission which include Comoros, Madagascar, Mauritius, Seychelles, Reunion and the island of Mayotte. Afte...

Resurrection of New Caledonian maskray Neotrygon trigonoides (Myliobatoidei : Dasyatidae) from synonymy with N. kuhlii, based on cytochrome-oxidase I ...

The maskray from New Caledonia, Neotrygon trigonoides CasteInau, 1873, has been recently synonymized with the blue-spotted maskray, N. kuhlii (Muller and Henle, 1841), a species with wide Indo-West Pacific distribution, but the reasons for this are u...

Effects of soot deposition on particle dynamics and microbial processes in marine surface waters

Large amounts of soot are continuously deposited on the global ocean. Even though significant concentrations of soot particles are found in marine waters, the effects of these aerosols on ocean ecosystems are currently unknown. Using a combination of...

Trichodesmium and other planktonic cyanobacteria in New Caledonian waters (SW tropical Pacific) during an El Nino episode

Contributions of filamentous and picoplanktonic cyanobacteria to the phytoplankton community structure were examined in New Caledonian waters during the 2001-2003 El Nino period at 2 ocean stations (Loyalty Channel and Santal Bay) and 1 coral-reef la...

Intermediate water flows in the western South Pacific : as revealed by individual Argo floats trajectories and a model re-analysis

Thanks to the autonomous Argo floats of the OUTPACE cruise (Oligotrophy to UlTra-oligotrophy PACific Experiment) and of the THOT (TaHitian Ocean Time series) project, some features of intermediate-flow dynamics, at around 1000 m depth, within the cen...
