A model-based evaluation of Marine Protected Areas: the example of eastern Baltic cod (Gadus morhua callarias L.)

The eastern Baltic cod stock collapsed as a consequence of climate-driven adverse hydrographic conditions and over fishing and has remained at historically low levels. Spatio-temporal fishing closures [Marine Protected Areas (MPAs)] have been impleme...

Experimental study of the turbulence intensity effects on marine current turbines behaviour. Part I: One single turbine

The ambient turbulence intensity in the upstream flow plays a decisive role in the behaviour of horizontal axis marine current turbines. Experimental trials, run in the IFREMER flume tank in Boulogne-Sur-Mer (France) for two different turbulence int...

Apport du satellite SPOT à la connaissance des écosystèmes récifaux coralliens. La végétation marine de l'île de Moorea, Polynésie française

Numerical simulation of the wake of marine current turbines with a particle method

This paper presents numerical computations of three bladed horizontal axis marine current turbines in a uniform free upstream current. The unsteady evolution of the turbine wake is taken into account by some three-dimensional software, developed to a...

First Evidence of Palytoxin and 42-Hydroxy-palytoxin in the Marine Cyanobacterium Trichodesmium

Marine pelagic diazotrophic cyanobacteria of the genus Trichodesmium (Oscillatoriales) are widespread throughout the tropics and subtropics, and are particularly common in the waters of New Caledonia. Blooms of Trichodesmium are suspected to be a pot...

Etude sur l'état des lieux de la pêche professionnelle dans le Parc naturel marin d'Iroise - Mesures réglementaires et mesures de gestion (Lot 2)

Sustainability of exploited marine ecosystems through protected areas: A viability model and a coral reef case study

Overexploitation of marine resources remains a problem worldwide. Many works advocate for the use of marine reserves as a central element of future stock management in a sustainable perspective. In the present paper, we address the influence of prote...

Surveillance du milieu de la grande rade de Nouméa - Suivi milieu marin SLN 2013/2014 : Campagne 2013

Dans le cadre de l'arrêté ICPE du 12 novembre 2009 autorisant la Société Le Nickel à exploiter son usine de traitement de minerai de nickel de Doniambo, la SLN a missionné SOPRONER pour réaliser la surveillance du milieu marin dans la G...

Colonization and release processes of viruses and prokaryotes on artificial marine macroaggregates

Marine organic aggregates are sites of high of viral accumulation; however, still little is known about their colonization processes and interactions with their local bacterial hosts. By taking advantage of a novel approach (paramagnetic functionaliz...
