Reproductive biology of the holothurians from major communities of the New Caledonian lagoon

The reproductive biology of nine species of aspidochirote holothurians from the majour communities of the New Caledonian lagoon has been analysed. The data were obtained from monthly sampling from 1978 to 1982 of their populations on reef slopes and ...

Sedimentation of particulate matter in the south-west lagoon of New Caledonia : spatial and temporal patterns

Suspended and sedimented particulate materials were assessed monthly at five sites on the south-west lagoon of New Caledonia, from May 1986 to April 1987. Sedimentation of particulate matter was measured using sediment traps for 24 h. Resuspension, w...

Halophyte species from New-Caledonia as a tool to protect estuaries and lagoon from heavy metal pollution

Dissolved organic matter influences N-2 fixation in the New Caledonian lagoon (Western Tropical South Pacific)

Specialized prokaryotes performing biological dinitrogen (N-2) fixation ("diazotrophs") provide an important source of fixed nitrogen in oligotrophic marine ecosystems such as tropical and subtropical oceans. In these waters, cyanobacterial photosynt...

Wave forcing and morphological changes of New Caledonia lagoon islets : insights on their possible relations

In the present study, we examine how waves may contribute to the morphological changes of islets in the New Caledonia lagoon. We collected in situ wave data to investigate their characteristics. Three types of waves are identified and quantified: (1)...

Evaluating management scenarios for fished resources of the New Caledonian lagoon using a spatially-explicit model.
