Prolifération de l’étoile de mer corallivore Acanthaster planci dans le lagon Sud-Ouest de Nouvelle-Calédonie : état de lieux en juin 2012 et im...

Fin 2011, des densités anormalement élevées de l'étoile de mer corallivore Acanthaster planci ont été signalées dans certaines zones du lagon. Les explosions démographiques de cette espèce constituent l'une des principales perturbations biol...

Influence of plankton concentration on gametogenesis and spawning of the black lip pearl oyster Pinctada margaritifera in Ahe atoll lagoon (Tuamotu ar...

Pearl culture industry represents one of the dominant business sector of French Polynesia. However, it still entirely relies on unpredictable spat collection success. Our aim was to assess the influence of natural plankton concentration fluctuations ...

Correction of the water column attenuation : application to the seabed mapping of the lagoon of New Caledonia using MERIS images

Features on the seabed can be mapped from remote sensing multi/hyperspectral imagery, provided that their effects on the measured reflectance spectrum can be made independent of those produced by the atmosphere and water column. The nonlinear effect ...
