Submarine slope failures are a likely cause for tsunami generation along the East Coast of the United States. Among potential source areas for such tsunamis are submarine landslides and margin collapses of Bahamian platforms. Numerical models of past events, which have ...

Maritime borders and coastal zones are susceptible to threats such as drug trafficking, piracy, undermining economical activities. At TNO Defence, Security and Safety various studies aim at improving situational awareness in a coastal zone. In this study we focus on mul...

L'insémination artificielle de la truite arc-en-ciel avec dilution du sperme

This work has been partly financed by ANR (France) project NT05-3 42213 to JE, by EU FP6-RTN project #505026 MOMAR-NET to MC, and by MINECO (Spain) project CTM2013-46718-R to RG. The French Ministry of Research financed ship, ROV and AUV time through the cruises Gravilu...

We present results of three-dimensional joint inversion of seismic, magnetotelluric, and gravity data over a marine salt dome. Such structures are difficult to image with a single method, and our results demonstrate how combining different techniques can yield improved ...

Abstract This study provides morphological and molecular data of a new parasite species found in the muscle layer of the intestinal tract of the South American silver catfish, Rhamdia quelen from Marajó Island region (Pará State, Brazil), an important fishery resource w...

La pollution de la mer peut être chronique ou accidentelle suivant qu'elle résulte des déversements urbains et industriels ou du rejet de matières nocives par suite de naufrages, de retombées d'engins balistiques ou d'ouverture de conduits et containers immergés. Dans l...

[1] Very rare, halogen-rich andesite melt inclusions (HRA) in bytownitic plagioclase phenocrysts (An89–90) from tephra fallout of the Izu arc volcanic front (Izu VF) provide new insights into the processes of fluid release from slab trenchward to the volcanic front in a...

Sediments deposited under lacustrine and marine conditions in the Sea of Marmara hold a Late Quaternary record for water exchange between the Black Sea and the Mediterranean Sea. Here we report a multiproxy data set based on oxygen and strontium isotope results obtained...

Abstract Efforts to attain good environmental status in the marine realm require decisions which cannot be done without knowledge of effects of different management measures. Given the wide diversity of marine ecosystems, multitude of pressures affecting it and the stil...

1. Plant diversity is an important driver of belowground ecosystem functions, such as root growth, soil organic matter (SOM) storage, and microbial metabolism, mainly by influencing the interactions between plant roots and soil. Dissolved organic matter (DOM), as the mo...

Les oeufs de merlu ont été rencontrés pour la première fois en janvier 1888, dans le Golfe de Naples, par RAFFAELE qui les a décrits (134). Ces oeufs sont pélagiques, ils flottent à la surface ou à une faible profondeur. Ils sont transparents, à vitellus homogène et pré...

Fish can alter food web structure through trophic cascades. While most studies conducted in oligotrophic subarctic lakes show strong top–down control on consumers in the presence of fish, several studies undertaken in eutrophic subarctic Lake Mývatn, Iceland, suggest th...

Lipids of the Arctic ctenophore Mertensia ovum, collected from Kongsfjorden (Svalbard) in 2001, were analysed to investigate seasonal variability and fate of dietary lipids. Total lipids, lipid classes and fatty acid and alcohol compositions were determined in animals, ...

Ce document est réalisé dans le cadre du projet « Système d'Informations Halieutiques » (SIH) de l'Ifremer, qui constitue le réseau d'observation des ressources halieutiques et des usages associés. Ce projet s'inscrit dans la mission de service d'intérêt public de l'Ifr...

International audience; Species richness is greater in places where the number of potential niches is high. Consequently, the niche may be fundamental for understanding the arrangement of life and especially, the establishment and maintenance of the well-known Latitudin...

Ce travail vise à décrire la gonadogenèse et le dimorphisme sexuel de croissance chez le bar Dicentrarchus labrax en élevage puis à étudier le déterminisme du sexe dans cette espèce. La gonadogenèse est étudiée par histologie dans une population constituée de 30 famille...
