Nickel and ocean warming affect scleractinian coral growth

The sensitivity of corals and their Symbiodinium to warming has been extensively documented; however very few studies considered that anthropogenic inputs such as metal pollution have already an impact on many fringing reefs. Thus, today, nickel rele...

UMR 5805 Environnements et Paléoenvironnements Océaniques et Continentaux

Étude et prévisions de la circulation océanique dans la ZEE de Nouvelle-Calédonie: courants, upwelling le long de la pente externe de Nouvelle-Cal...

Modélisation et prévision de la dynamique marine de la ZEE: description bibliographique de la dynamique de la ZEE, étude numérique permettant la simulation ZEE, compréhension et description des écosystèmes côtiers grâce à un outil numériqu...

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...

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 ...

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 ...

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...

Concentrations en chlorophylle dans le Pacifique tropical sud-ouest : comparaison avec d'autres aires océaniques tropicales

Chromis durvillei : une nouvelle espèce de Pomacentridae de l’île de la Réunion (France, océan Indien) et premier signalement pour l’île de C...

Following the volcanic eruption of April 2007 at Reunion Island, 12 specimens of the pomacentrid genus Chromis were collected at sea surface. One of these fishes was a C. chrysura known from the reef Island fauna. The others have enlarged eyes. Among...
