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 ...

Influence of settings management and protection status on recreational uses and pressures in marine protected areas

Coastal populations and tourism are growing worldwide. Consequently outdoor recreational activity is increasing and diversifying. While Marine Protected Areas (MPAs) are valuable for mitigating anthropogenic impacts, recreational uses are rarely moni...

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...

Can the non-market economy help to improve diet quality? Findings from a survey in New Caledonia

The Pacific archipelago of New Caledonia is undergoing a nutritional transition that began several decades ago. In a political context dominated by questions of self-determination that reveal deep divisions, agriculture also mirrors this dichotomy, o...
