Accident du 1er avril 2009 sur le site industriel de Vale Nouvelle-Calédonie

Le 1er avril 2009 à midi, environ 3 m3 d'acide sulfurique se sont déversés dans la rivière « Creek de la Baie Nord ». C'est la rupture d'un joint défectueux sur le site de Vale Nouvelle-Calédonie qui est à l'origine de cet accident. Le bass...

Fréquence environnement n°21

jeu de l'octoquiz

Il s'agit d'un jeu ludique au travers duquel 8 questions sont posées. Ces questions permettent d'aborder différentes problématiques telles que les espèces envahissantes, l'acidification des océans, la dégradation des sols...

Biological data of pygmy killer whale (Feresa attenuata) from a mass stranding in New Caledonia (South Pacific) associated with hurricane Jim in 2006

Despite its distribution throughout the tropics and subtropics, the pygmy killer whale (Feresa attenuata) is one of the most poorly known species of odontocetes (Cetacea: Delphinidae). We used the opportunity of a mass stranding of six animals in New...

A framework for mapping small-scale coastal fisheries using fishers' knowledge

Collecting spatial information on fisheries catch and effort is essential to understanding the spatial processes of exploited population dynamics and to manage heterogeneously distributed resources and uses. The use of fishers' knowledge through geog...

Harvesting effects on functional structure and composition of tropical invertebrate assemblages

Anthropogenic disturbances affect ecosystem structure and functioning. The quantification of their impacts on highly diverse and structurally complex ecosystems, such as coral reefs, is challenging. These communities are facing rising fishing pressur...

Checklist of the fishes of New Caledonia, and their distribution in the Southwest Pacific Ocean (Pisces)

A checklist of the fishes of New Caledonia is presented. A total of 2328 species in 246 families have been recorded from the region. Eight of these species are not native, but have been introduced. Five fish families are represented only by introduce...

Spatial and temporal variability of zooplankton off New Caledonia (Southwestern Pacific) from acoustics and net measurements

Spatial and temporal distribution of zooplankton off New Caledonia in the eastern Coral Sea was studied during two multidisciplinary cruises in 2011, during the cool and the hot seasons. Acoustic measurements of zooplankton were made using a shipborn...

Remote High-Definition Rotating Video Enables Fast Spatial Survey of Marine Underwater Macrofauna and Habitats

Observing spatial and temporal variations of marine biodiversity from non-destructive techniques is central for understanding ecosystem resilience, and for monitoring and assessing conservation strategies, e.g. Marine Protected Areas. Observations ar...
