Fishing for space: Fine-scale multi-sector maritime activities influence fisher location choice

The European Union and other states are moving towards Ecosystem Based Fisheries Management to balance food production and security with wider ecosystem concerns. Fishing is only one of several sectors operating within the ocean environment, competin...

La mer et l'océan porteurs d'éthique

This article has for objective to put forward the ethical values of the sea and the ocean. After a reminder(abs of the marine origin of life on earth and what the human always carries in him tracks of this origin, we underline several characteristics...

Environmental and geographical factors structure soil microbial diversity in New Caledonian ultramafic substrates: A metagenomic approach

Soil microorganisms play key roles in ecosystem functioning and are known to be influenced by biotic and abiotic factors, such as plant cover or edaphic parameters. New Caledonia, a biodiversity hotspot located in the southwest Pacific, is one-third ...

A moderate melting model for the Voring margin (Norway) based on structural observations and a thermo-kinematical modelling: Implication for the meani...

High P-wave velocities (7.1-7.8 km/s) lower crustal bodies (LCBs) imaged along volcanic margins are commonly interpreted as plume and break-up-related thick mafic underplating. This interpretation is partly challenged in this paper based on new seism...

An updated checklist of the marine fish fauna of Reunion Island, South-Western Indian Ocean

The ichthyofauna of Reunion Island, Southwestern Indian Ocean, was sampled during several ecological and artisanal fisheries studies. Information from these investigations and from other sources were included to compile the present checklist of the m...

Designing indicators for assessing the effects of marine protected areas on coral reef ecosystems: A multidisciplinary standpoint

The present paper aims at identifying and assessing indicators of the effects of Marine Protected Areas (MPAs) in coral reef regions, based on a bibliography review in ecology, economics and social sciences. First the various effects Studied within e...

Biogeochemical and biological impacts of diazotroph blooms in a low-nutrient, low-chlorophyll ecosystem : synthesis from the VAHINE mesocosm experimen...

In marine ecosystems, biological N-2 fixation provides the predominant external source of nitrogen (N; 140aEuro-+/- aEuro-50aEuro-TgaEuro-NaEuro-yr(-1)), contributing more than atmospheric and riverine inputs to the N supply. Yet the fate and magnitu...

Morphology and distribution of dolines on ultramafic rocks from airborne LiDAR data : the case of southern Grande Terre in New Caledonia (SW Pacific)

Dolines are closed geomorphological depressions which are surface manifestations of karstic systems. Usually developed on limestones, they also typify the morphology of the New Caledonian landscape, particularly on the southern massif of the main isl...
