Bio-optical characterization and ocean colour inversion in the Eastern Lagoon of New Caledonia, South Tropical Pacific

The Eastern Lagoon of New Caledonia (ELNC) is a semi-enclosed system surrounded by an extensive coral reef barrier. The system has been suffering impacts from climate variability and anthropogenic activities, including mining exploitation. Satellite ...

Determining the age of tropical tunas in the Indian Ocean from otolith microstructures

The Indian Ocean Tuna Tagging Program (IOTTP) provided a unique opportunity to assess the viability of estimating the age of tropical tunas from the micro-structural features of otoliths. Here, we analyzed the length measurements and micro-increment ...

L'élévation récente du niveau marin et l'érosion côtière : le cas d'îles océaniques du Pacifique

Le changement climatique induit une élévation du niveau marin qui, loin d'être uniforme, présente une variabilité régionale importante liée en premier lieu aux variations de température des océans. Dans certaines régions de l'océan, cette ...

Sequential invasions by fruit flies (Diptera: Tephritidae) in Pacific and Indian Ocean islands: A systematic review

The aim of our review was to examine the cases of Tephritidae invasions across island systems in order to determine whether they follow a hierarchical mode of invasion. We reviewed the literature on factors and mechanisms driving invasion sequences i...

Accrétion océanique et déformation dans la partie méridionale du bassin Nord-Fidjien: résultats préliminaires de la campagne océanographique SE...

Seismic, Seabeam, magnetic and gravimetrie surveys in the southern part of the N-Fiji basin were conducted during the SEAPSO LEG III Cruise. The active spreading axis was recognized between 17°30'S and 21°S. It consists of a continuous N-S Ridge cr...

Genetic structure of the reef grouper Epinephelus merra in the West Indian Ocean appears congruent with biogeographic and oceanographic boundaries

The reef fauna connectivity of the West Indian Ocean (WIO) is one of the least studied globally. Here we use genetic analyses of the grouper Epinephelus merra (Bloch 1793) to determine patterns of connectivity and to identify barriers to dispersal in...

The impact of FAD innovation on the performance of US tuna purse seine operations in the Pacific Ocean

It is generally accepted that innovations in tuna purse seine technology have affected fishing operations and the traditional measurement of fishing effort, days fished including searching time. Not much is known, however, about the actual effects of...

Relationships between fish length and otolith length for nine fish species from the Mediterranean basin, Kerguelen Islands, and Pacific Ocean

Effects of geomorphological zones, reefs and seasons on coral reef fish communities of Réunion Island, Mascarene Archipelago, SW Indian Ocean
