Rupture de l’émissaire : Analyse des eaux de mer autour du point de cassure du diffuseur, Analyse de l’effluent industriel (physico-chimie et to...

Suite à la rupture du tuyau d'évacuation des rejets liquides dont le constat a été fait le 11/11/13, le laboratoire AEL/LEA a été mandaté par Vale NC pour la réalisation d'une étude visant à évaluer les impacts potentiels de l'incident...

Plan de suivi de la qualité des eaux de surface - Raffinerie & Usine de préparation du minerai - Centre industriel - Annexe III-C-4-2

Le but de ce document est de présenter le programme de suivi et de surveillance mis en ouvre par Goro Nickel pour surveiller la qualité des eaux de surface et des écosystèmes associés aux alentours de ses installations industrielles du plateau d...

Concentration en métaux dans les organismes transplantés

Certains organismes marins accumulent les métaux. Mesurer la concentration en métaux dans ces organismes est donc particulièrement intéressant. En effet, en la mesurant, on obtient une bonne image de l'évolution de la concentration en métaux d...

Waterborne nickel bioaccumulation in Gammarus pulex: Comparison of mechanistic models and influence of water cationic composition

The biodynamic and saturation models offer promising lines of enquiry to predict the bioaccumulation of metals by aquatic organisms. However, in order to construct these models, the accumulation strategies have to be defined for each metal/organism c...

Interspecific comparison of Cd bloaccumulation in European Pectinidae (Chlamys varia and Pecten maximus)

The uptake and loss kinetics of Cd were determined in two species of scallops from the European coasts, the variegated scallop Chlamys varia and the king scallop Pecten maximus, following exposures via seawater, phytoplankton and sediment using highl...

High rate algal pond treatment for water reuse in a marine fish recirculation system: Water purification and fish health

Regardless of the degree of closure of a recirculation system, effluents are produced and replacement water is needed, which limits the possibility of locating a seawater production system away from the shoreline. At the Palavas Ifremer station, in t...

How many genera of vascular plants are endemic to New Caledonia ? A critical review based on phylogenetic evidence

New Caledonia is a biodiversity hotspot located in the south-western Pacific, well known for its rich, unique and endangered flora. The island flora has a high level of endemism not only at the species level (75%), but also at the generic and family ...

Discovery of Early Cretaceous rocks in New Caledonia; new geochemical and U-Pb zircon age constraints on the transition from subduction to marginal br...

New U-Pb dating of detrital zircon and geochemical features of Permian-Mesozoic arc-derived volcanic rocks and volcaniclastic turbidites (greywackes), when compared to the volcanic rocks associated with unconformable Late Cretaceous shallow-water sed...

Mechanisms of Trichodesmium demise within the New Caledonian lagoon during the VAHINE mesocosm experiment

The globally important marine diazotrophic cyanobacterium Trichodesmium is abundant in the New Caledonian lagoon (southwestern Pacific Ocean) during austral spring/summer. We investigated the cellular processes mediating Trichodesmium mortality from ...
