Marine birds of d'Entrecasteaux Reefs (New Caledonia, southwestern Pacific) - Diversity, abundance, trends and threats

We present the first information on waterbirds, especially breeding marine birds, from three islands of d'Entrecasteaux Reefs (Surprise, Fabre and Huon), northern New Caledonia, south western Pacific. Using different sampling and counting techniques...

Quelques considérations sur la distribution des oiseaux marins : commentaire du livre de Warren B. King "Seabirds of the tropical Pacific Ocean"

Conférence faite au cours de l'assemblée générale de la Société Calédonienne d'Ornithologie le 24 avril 1968 par Philippe Bourret, océanographe biologiste au centre ORSTOM de Nouméa. Le conférencier donne une définition des oiseaux de mer...

Marine mineral occurrences and deposits of the economic exclusive zones. Marmin a database

The Marmin database inventories the mineral prospects and deposits, primarily those in the exclusive economic zone (EEZ). The database offers a review of the variety of potential sites for exploration and development of sub-marine mineral resources.;...

Experimental study of the turbulence intensity effects on marine current turbines behaviour. Part II: Two interacting turbines

The future implantation of second generation marine current turbine arrays depends on the understanding of the negative interaction effects that exist between turbines in close proximity. This is especially the case when the turbines are axially alig...

Numerical and Experimental Study of the Interaction between two Marine Current Turbines

The understanding of interaction effects between marine energy converters represents the next step in the research process that should eventually lead to the deployment of such devices. Although some a priori considerations have been suggested recent...

Remote High-Definition Rotating Video Enables Fast Spatial Survey of Marine Underwater Macrofauna and Habitats

Observing spatial and temporal variations of marine biodiversity from non-destructive techniques is central for understanding ecosystem resilience, and for monitoring and assessing conservation strategies, e.g. Marine Protected Areas. Observations ar...

Effluents from land based marine farms: nature, treatment, valorisation, modelisation. Applications to fish and shrimp rearing

Fish culture (seabass, turbot...) on the French metropolitan coast, and shrimp culture in the overseas territories (essentially New Caledonia and Tahiti) are subject to a regular development through land based farms. Three thematic of research on aqu...
