Structure and temporal fluctuations of two interdital seagrass-bed communities in New Caledonia (SW Pacific ocean)

The structure and trophic organisation of two intertidal seagrass-bed communities (#Halodule uninervis$ and #Thalassia hemprichii$ were examined on the South-West coast of New Caledonia (SW Pacific Ocean), from April 1989 to March 1990. Five benthic ...

Structure of the barents sea from seismic refraction

The Barents Sea is underlain by a thick (up to 5 km) sedimentary basin. Seismic refraction has outlined four main velocity discontinuities which have been correlated with geological units on the basis of the geological history of the region. The basi...

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...

Reproduction of the hawaiian strain of pacific blue shrimp Litopenaeus stylirostris in New Caledonia.

The Pacific blue shrimp Litopenaeus stylirostris was introduced in New Caledonia thirty years ago. Because of its high inbreeding, a SPF strain domesticated in Hawaii, genetically differentiated from the Caledonian strain, had to be imported. The two...

L'acidification de l'Océan

This text, directed to the general public exposes, in first part, on the educational point of view, the mechanisms of ocean acidification resulting from the trapping of the carbon dioxide. Then the text presents a state of the knowledge about the spe...

Un bilan de la télédétection appliquée aux milieux coralliens

The aim of this paper is to present in a practical fashion the status of the use of remote sensing for the study of coral reef environments through the analysis of work published in the years 1980-2000. We review the scales of the potential work and ...

Expression, tissue localization and synergy of antimicrobial peptides and proteins in the immune response of the oyster Crassostrea gigas

Diverse families of antimicrobial peptides and proteins have been described in oysters. We investigated here how antimicrobials are involved in the immune response against a pathogenic strain of Vibrio splendidus. Oyster antimicrobials were shown to ...

Guide pour le suivi de la qualité du milieu marin en Nouvelle-Calédonie

This guide is intended to facilitate the implementation of specifications for marine environmental monitoring in New Caledonia. It is intended for public or private environmental actors. He provides a set of information on marine monitoring: summary ...

A general framework for indicator design and use with application to the assessment of coastal water quality and marine protected area management

Environmental management decisions based upon indicators are the end point of a process involving stakeholders and scientists. These steps should be explicit and follow a chronology. This paper presents a general framework for the design and use of m...

Deep circulation in the equatorial Atlantic Ocean

In the Atlantic Ocean, the northward export of warm surface water is compensated by a southward flow of cold North Atlantic Deep Water (NADW). The NADW is transported southward along the American continental margin within the Deep Western Boundary Cu...
