Géodiversité sous-marine de Nouvelle-Calédonie. 1ère partie

The object of this article is to offer a synthesis of the knowledge clarifying the originality and the diversity of the submarine geological formations of the New Caledonian EEZ. A reminder is given onto the geologic history of the region, based upon...

Selection and characterization of potential probiotic bacteria for Litopenaeus stylirostris shrimp hatcheries in New Caledonia

In New Caledonia, shrimp hatcheries are confronted with mass mortality in the larval stages, a phenomenon poorly understood as no specific causative agent has been identified. This has resulted in an excessive use of prophylactic antibiotics, althoug...

Introduction et invasion de l'algue tropicale Caulerpa taxifolia en Méditerranée nord-occidentale

The tropical alga Caulerpa taxifolia (Vahl) C. Agardh has been displayed over the last fifteen years in tropical aquaria at the Oceanographic Museum, Monaco. Its accidental introduction into the natural environment dates from 1984. It developed first...

Biogeochemical and biological impacts of diazotroph blooms in a low-nutrient, low-chlorophyll ecosystem : synthesis from the VAHINE mesocosm experimen...

In marine ecosystems, biological N-2 fixation provides the predominant external source of nitrogen (N; 140aEuro-+/- aEuro-50aEuro-TgaEuro-NaEuro-yr(-1)), contributing more than atmospheric and riverine inputs to the N supply. Yet the fate and magnitu...

Influence of CDOM and Particle Composition on Ocean Color of the Eastern New Caledonia Lagoon during the CALIOPE Cruises;Ocean remote sensing and moni...

Ocean color of tropical lagoons is dependent on bathymetry and bottom type, as well as input of coastal living and mineral particles and chromophoric dissolved organic matter (CDOM). The New Caledonia lagoon lies in the Southwestern Tropical Pacific ...

Ni cycling in mangrove sediments from New Caledonia

Covering more than 70% of tropical and subtropical coastlines, mangrove intertidal forests are well known to accumulate potentially toxic trace metals in their sediments, and thus are generally considered to play a protective role in marine and lagoo...

Post-obduction carbonate system development in New Caledonia (Nepoui, Lower Miocene)

For the first time, depositional models of Lower Miocene carbonate systems from New Caledonia (Southwest Pacific) are proposed, on the basis of a sedimentological and paleoenvironmental study of both cores and outcrops. In the Nepoui area, two distin...

An optimised passive acoustic sampling scheme to discriminate among coral reefs' ecological states

In the present era of rapid global change, innovative monitoring methods can greatly enhance our ability to detect ecological disturbances and prioritise conservation areas in a timely and cost-effective manner. While Passive Acoustic Monitoring (PAM...
