Forum BIOdiversité des Ecosystèmes Coralliens, 30 octobre-4 novembre, Nouméa (Nouvelle-Calédonie)
The Grande Terre of New Caledonia is enclosed by one of the longest barrier reefs in the world. For the first time, the fore-reef slopes of this barrier reef have been sampled by dredging, from 40 to 320 m deep, in order to analyze their sedimentological and biological characteristics. The rocks and sediments can be divided into seven...
The diversity of oceanic and continental reef structures of New Caledonia is reviewed, taking into account their geological history and in particular, that since the last interglacial period. To guide this review, a new path is provided by following the diversity of units that have been mapped and characterized using high spatial resolution...

The timing of the last deglaciation is important to our understanding of the dynamics of large ice sheets and their effects on the Earth's surface. Moreover, the disappearance of the glacial ice sheets was responsible for dramatic increases in freshwater fluxes to the oceans, which probably disturbed the ocean's thermohaline circulation and,...
We investigated surface carbonate sediments at 33 sites on the outer shelf and slope around New Caledonia (163°–167°E, 20°–23°S), at water depths of 75–720 m. Four carbonate sedimentary facies are recognized on the basis of sediment size fractions and predominant constituents: Facies 1, encrusted grains (rhodoliths and macroids), bryozoa, and...
The barrier reef tract of New Caledonia is the second largest in the world enclosing lagoons of variable width. The Late Quaternary evolution of these barrier reefs and lagoons is poorly known. A recent high resolution seismic and multibeam bathymetry survey was carried out in the south-western lagoon from shoreline to open ocean across the...
