Segregation in diet between Black Noddy (Anous minutus) and Brown Noddy (A. stolidus) from the southern lagoon of New Caledonia

The Black Noddy (Anous minutus) and the Brown Noddy (A. stolidus) occur sympatrically in the Southern Lagoon of New Caledonia, breeding on islets located at the edge of a wide, productive coral-reef lagoon next to oceanic waters enriched by a seasona...

Evolution of dissolved and particulate chromophoric materials during the VAHINE mesocosm experiment in the New Caledonian coral lagoon (south-west Pac...

In the framework of the VAHINE project, we investigated the spectral characteristics and the variability of dissolved and particulate chromophoric materials throughout a 23-day mesocosm experiment conducted in the south-west Pacific at the mouth of t...

New Caledonia Lagoon : a threatened paradise under anthropogenic pressure ?;Lagoons : habitat and species, human impacts and ecological effects

The French archipelago of New Caledonia hosts one of the three most extensive reef systems in the world and was partly added to the UNESCO World Heritage List in 2008. In the very specific context of rapidly growing land-based mining extraction and o...

Influence of water column chlorophyll concentration on bathymetric estimations in the lagoon of New Caledonia, using several MERIS images

An estimation of bathymetry in the optically complex lagoon of New Caledonia was performed from multispectral satellite images. Bathymetric estimation was obtained with Medium Resolution Imaging Spectrometer (MERIS) images acquired at different dates...

Contribution and pathways of diazotroph-derived nitrogen to zooplankton during the VAHINE mesocosm experiment in the oligotrophic New Caledonia lagoon

In oligotrophic tropical and subtropical oceans, where strong stratification can limit the replenishment of surface nitrate, dinitrogen (N-2) fixation by diazotrophs can represent a significant source of nitrogen (N) for primary production. The VAHIN...

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 ...

Ephemeral and localized outbreaks of the coral predator Acanthaster cf. solaris in the southwestern lagoon of New Caledonia

Outbreaks of the coral predator Acanthaster spp., the crown-of-thorns seastar (COTS), cause major coral declines across the Indo-Pacific. However, the processes surrounding the initiation and propagation of COTS outbreaks are still unclear. We observ...
