Données économiques maritimes françaises 1998

The purpose of this book is to value the economic significance of marine-related activities in France. Each industrial, or public non-commercial, sector is characterized by key figures relating to annual turnover, value added, employment and budget. ...

A mass stranding of seven Longman's beaked whales (Indopacetus pacificus) in New Caledonia, South Pacific

Seven Longman's beaked whales (Indopacetus pacificus) stranded together in southern New Caledonia on 16 November 2013 (one adult male, two adult females, two subadult females, one calf, and one unknown). At this time, we have no evidence to suggest t...

Chemotypes and biomarkers of seven species of New Caledonian liverworts from the Bazzanioideae subfamily

Volatile components of seven species of the Bazzanioideae sub-family (Lepidoziaceae) native to New Caledonia, including three endemic species (Bazzania marginata, Acromastigum caledonicum and A. tenax), were analyzed by GC-FID-MS in order to index th...

A spatially explicit integrative model for estimating the risk of wildfire impacts in New-Caledonia

In this study, we present a spatially explicit bayesian model which is able to predict the distribution of potential fire ignition at a grid resolution of over the entire main island of New-Caledonia. This statistical model, when used in conjunction ...

Abundance, richness and composition of lianas in forest communities along an elevation gradient in New Caledonia

Background: Lianas are an abundantand dynamic component of tropical forests, and their abundance ispredicted to increase with global change. A better understandingof factors that explain their distribution is required, especially onoceanic islands fo...

Bleaching forces coral's heterotrophy on diazotrophs and Synechococcus

Coral reefs are threatened by global warming, which disrupts the symbiosis between corals and their photosynthetic symbionts (Symbiodiniaceae), leading to mass coral bleaching. Planktonic diazotrophs or dinitrogen (N-2)-fixing prokaryotes are abundan...

On the Influence and Correction of Water Content on pXRF Analysis of Lateritic Nickel Ore Deposits in the Context of Open Pit Mines of New-Caledonia

In a number of applications, the use of portable X-ray fluorescence (pXRF) instruments offers a time and cost-saving alternative to standard laboratory instruments. This is particularly true in a mining context where decisions must be taken quickly i...

Earliest Eocene (53 Ma) convergence in the Southwest Pacific; evidence from pre-obduction dikes in the ophiolite of New Caledonia.

Uncertainty about timing and location of the initiation of convergence in the western and south western Pacific greatly hinders accurate plate tectonic reconstructions of subduction systems in that area. The chemistry and age of dikes intruding mantl...

The Norfolk Ridge: A Proximal Record of the Tonga‐Kermadec Subduction Initiation

Norfolk Ridge bounds the northeastern edge of the continent of Zealandia and is proximal to where Cenozoic Tonga-Kermadec subduction initiation occurred. We present and analyze new seismic reflection, bathymetric and rock data from Norfolk Ridge that...
