Clay mineral evolution in the central Okinawa Trough since 28 ka: Implications for sediment provenance and paleoenvironmental change

The Okinawa Trough is a natural laboratory for the study of later Quaternary land-ocean interaction and paleoenvironmental changes. In this study we reconstruct the evolution of clay mineral assemblages in Core DGKS9604 retrieved from the central Oki...

Impact of plant root functional traits and associated mycorrhizas on the aggregate stability of a tropical Ferralsol

In many tropical regions, such as New Caledonia, soil erosion from anthropogenic activities and subsequent ecological restoration are major issues that require detailed soil and vegetation data for the production of management plans. To determine if ...

Does arbuscular and ectomycorrhizal fungal inoculation improve soil aggregate stability? A case study on three tropical species growing in ultramafic ...

In many tropical regions, soil erosion from anthropogenic activities and subsequent ecological restoration are major issues. Revegetation would be an efficient way to mitigate soil degradation. Some plant and mycorrhizal species are more useful than ...

Lagoon islets as indicators of recent environmental changes in the South Pacific – The New Caledonian example

The question of the impacts of climate change and sea level rise on small islands is currently much discussed. The many thousands of Pacific islands in their different contexts (geodynamic, climatic, etc.) and the insufficient data available explain ...

Réhabilitation des sites miniers orphelins en Province sud

Le présent document constitue un état des lieux général 2009 des sites miniers orphelins localisés en province Sud de la Nouvelle-Calédonie en vue d'une future réhabilitation. Les « mines orphelines » sont d'anciennes mines abandonnées ou c...

Cyclones tropicaux et interventions anthropiques. La question de l'érosion des décharges minières en Nouvelle-Calédonie.

Rapport relevant le problème de l'accroissement du volume des déblais provenant de l'érosion des décharges des mines de nickel, le rôle déterminant du climat dans ce phénomène et l'absence de mesures de protection.
