Observations sur site et modélisation de la dispersion du panache à proximité de la zone de déversement pour le projet Nickel INCO Goro dans le Ca...

Rapport présentant les mesures et la modélisation du panache du rejet de l'effluent dans le canal de la Havannah. Les mesures ont pour but de comprendre les mouvements du courant à proximité du pipeline de déversement prévu et le long du couloi...

La pêche

La Nouvelle-Calédonie, grâce à sa situation en plein Océan Pacifique et son immense lagon, constitue un terrain de pêche idéal. Différents types de pêche sont pratiqués. La pêche professionnelle hauturière se pratique en pleine mer à l'a...

Activité magmatique, tectonique et hydrothermale actuelle sur la Dorsale Est Pacifique entre17°-et 19°S(campagne NAUDUR)

The submersible-study of four segments of the East Pacific Rise between 17 degrees and 18 degrees 40'S, where the spreading rate is greater than 150 mm/a, allows us to confirm the variability of the accretion processes. The segment between 17 degrees...

Activité tectonique, magmatique et hydrothermale autour des triples jonctions de16°50'S-173°30'E et de l6°30'S-l76°10E dans le bassin nord fidjie...

The aim of the HYFIFLUX-SONNE 99 cruise was the geological, biological and chemical study of the 2 triple-junctions characterizing the oceanic accretion in the North Fiji Basin. Multibeam bathymetric coverage, in situ observations and sampling confir...

Les fonds marins vus de l'espace

This text is focused on the popularization of the general public, edited in a magazine connected to the sea. It explicits, in first part, all the factors which make that the surface of the sea is not horizontal. In second part are introduced the prin...

Small-scale FADs-associated fishing techniques used in the Pacific region

Over the last 16 years, the Secretariat of the Pacific Community (SPC - formerly the South Pacific Commission) has been developing and providing information on mid-water fishing techniques targeting the larger, deeper-swimming tunas that aggregate ar...

Using cognitive maps to investigate fishers' ecosystem objectives and knowledge

This paper presents a survey of French Eastern English Channel fishers' observations of the past and current state of the marine ecosystem and their wishes for the future, as a first step towards formulating management objectives. Twenty-nine semi-di...

Adult and larval traits as determinants of geographic range size among tropical reef fishes

Most marine organisms disperse via ocean currents as larvae, so it is often assumed that larval-stage duration is the primary determinant of geographic range size. However, empirical tests of this relationship have yielded mixed results, and alternat...

ENSO signals in the vicinity of New Caledonia, South Western Pacific

Data collected in an area enclosing New Caledonia are analysed both for the open ocean (17 degrees S-27 degrees S, 169 degrees E-170 degrees E; 1972-1992) and for one point in its lagoon (1967-1993), in order to improve our knowledge of the regional ...

Les énergies marines renouvelables : qu'est-ce que c'est ? Quelles perspectives en Nouvelle-Calédonie.

This text presents a review of the various technologies for exploitation of renewable marine energy resources. Il exposes the solutions offered by tide and currents, swell and waves, the marine wind energy, the Ocean Thermal Energy, the osmotic energ...
