Spatial distribution of small pelagic fish in the lagoon of New Caledonia;Proceedings of the 6th international coral reef symposium

Two acoustic surveys have been done in the lagoon all around New Caledonia, with a digital integrator. The cruises lasting two weeks were done at six month interval. Much information has been obtained on stock biomass and spatial distribution of fish...

Comparative ichthyotoxicity of shallow and deep water sponges of New Caledonia;Proceedings of the sixth international coral reef symposium

A survey of comparative ichthyotoxicity in marine sponges from shallow and deep water in the Southern province of New Caledonia was conducted. Test fish #Gambusia affinis$ (#Vertebrata, Pisces$) were exposed to aqueous macerates of 30 shallow water a...

The echinoderms of the soft bottoms of the South-Western lagoon of New Caledonia;Proceedings of the sixth international coral reef symposium

A bionomic mapping survey of the soft bottoms of the South-Western lagoon of New Caledonia was carried out by dredging. From analysis of the sediments and the fauna and flora found in 489 dredgings, it was possible to define three main benthic commun...

Spatial patterns and short-term changes of coral assemblages along a cross-shelf gradient in the southwestern lagoon of New Caledonia

Coral reef assemblages generally form gradients of spatial structures which are governed by a variety of interacting physical and biological processes that vary in intensity, frequency, and spatial scale. Assessing the structure of contemporary reef ...

Distributions and abundances of sublineages of the N-2-fixing cyanobacterium Candidatus Atelocyanobacterium thalassa (UCYN-A) in the New Caledonian co...

Nitrogen (N-2) fixation is a major source of nitrogen that supports primary production in the vast oligotrophic areas of the world's oceans. The Western Tropical South Pacific has recently been identified as a hotspot for N-2 fixation. In the Noumea ...

The same but different: stable isotopes reveal two distinguishable, yet similar, neighbouring food chains in a coral reef

Application of the support vector regression method for turbidity assessment with MODIS on a shallow coral reef lagoon (Voh-Kone-Pouembout, New Caledo...

Particle transport by erosion from ultramafic lands in pristine tropical lagoons is a crucial problem, especially for the benthic and pelagic biodiversity associated with coral reefs. Satellite imagery is useful for assessing particle transport from ...

Major Sources of Organic Matter in a Complex Coral Reef Lagoon: Identification from Isotopic Signatures (?13C and ?15N)
