Affleurements des roches profondes de la croûte océanique et du manteau sur le mur sud de la fracture Kane (Atlantique central) : observations par s...

The aim of the 20 Nautile dives of the recent Kanaut cruise was the study of the Kane Fracture Zone from its intersection with the Mid-Atlantic Ridge up to 80 km to the west. The dives have been conducted along four massifs located along the southern...

Age estimation and growth of some deep-sea fish from the northeast Atlantic ocean

Age is a necessary parameter used in population dynamics to assess the state of exploited resources. This parameter is poorly known for most deep-sea species (depth > 400 m). This work focused on age estimation from otoliths of Alepocephalus bairdii ...

Two new species of Platoma (Schizymeniaceae) from the western South Pacific Ocean

Recent collections in northern New Zealand and New Caledonia revealed a single undescribed species of Platoma in each of these countries. Platoma novae-zealandiae sp. nov. is distinguished from its New Caledonian congener by its less foliose habit, s...

Mean circulation of the upper layers of the western equatorial Pacific Ocean

Hydrographic (0-1000 dbar) and direct current measurements (0-600 dbar) along 165-degrees-E (20-degrees-S-10-degrees-N) between January 1984 and July 1991 are used to investigate the mean circulation and its relationships with the distributions of sa...

Nd isotope constraints on ocean circulation, paleoclimate, and continental drainage during the Jurassic breakup of Pangea

The breakup of Pangea and onset of growth of the Pacific plate led to several paleoenvironmental feedbacks, which radically affected paleoclimate and ocean chemistry during the Jurassic. Overall, this period was characterized by intense volcanic dega...

Checklist of the fishes of New Caledonia, and their distribution in the Southwest Pacific Ocean (Pisces)

A checklist of the fishes of New Caledonia is presented. A total of 2328 species in 246 families have been recorded from the region. Eight of these species are not native, but have been introduced. Five fish families are represented only by introduce...

Mayotte Island: another important green turtle nesting site in the southwest Indian Ocean

Situated in the north of the Mozambique Channel, Mayotte is the easternmost island of the Comoros Archipelago. From 1998 to 2005, Grande Saziley beach was monitored daily for green turtle Chelonia mydas nesting activity. Track surveys were monitored ...
