Isotopic records from archeological giant clams reveal a variable climate during the southwestern Pacific colonization ca. 3.0 ka BP [Plus Corrigendum...

The Lapita colonization,which occurred in the late Holocene, is one of the most remarkable prehistorical human colonizations. To explore the possible influence of El Niño–Southern Oscillation (ENSO) on this event, bulk oxygen (δ18Oshell) ...

Croissance et Société bleues : quels intérêts et perspectives pour la Nouvelle-Calédonie

This article calls back first of all a set of facts relative to the main stakes considering sea and ocean so much on the economic point of view, in the scientific technological and innovative fields, in the governance aspects as also in the culture a...

Structure and rifting evolution of the northern Newfoundland Basin from Erable multichannel seismic reflection profiles across the southeastern margin...

We present the results from processing and interpreting five lines from the 1992 Erable multichannel seismic reflection experiment extending from the southeastern margin of Flemish Cap into the northern Newfoundland Basin. These profiles reveal signi...

From the western boundary currents to the Pacific Equatorial Undercurrent: Modeled pathways and water mass evolutions

The hydrological and geochemical properties of the waters constituting the Pacific Equatorial Undercurrent (EUC) determine the properties of the equatorial cold tongue. Understanding and quantifying the various EUC origins is therefore of prime impor...

Update of the tsunami catalogue of New Caledonia using a decision table based on seismic data and marigraphic records

Fourteen years ago, the 26 December 2004 Indian Ocean tsunami demonstrated the destructional capability of tsunamis to the entire world. Since then, many research programs have been initiated to try to understand the phenomenon and its related hazard...

The East Caledonian Current : a case example for the intercomparison between AltiKa and in situ measurements in a boundary current

This paper presents an assessment of SARAL/AltiKa satellite altimeter for the monitoring of a tropical western boundary current in the southwestern Pacific Ocean: the East Caledonian Current. We compare surface geostrophic current estimates obtained ...

Two New Genera and Species of Ophiuroid (Echinodermata) from Hydrothermal Vents in the East Pacific

Prior to this study, two species of ophiuroid had been described from hydrothermal vent sites, and another from methane cold seeps, all from the Atlantic Ocean. Although ophiuroids have occasionally been reported from vents in the Pacific Ocean as we...

A global wave parameter database for geophysical applications. Part 2: Model validation with improved source term parameterization

A multi-scale global hindcast of ocean waves is presented that covers the years 1994-2012, based on recently published parameterizations for wind sea and swell dissipation [Ardhuin, F., Rogers, E., Babanin, A., Filipot, J.-F., Magne, R., Roland, A., ...

Crustal structure of the basin and ridge system west of New Caledonia (southwest Pacific) from wide-angle and reflection seismic data.

[1] During the Zoneco 11 marine geophysical survey (September 2004), two deep reflection seismic profiles recorded by ocean bottom seismometers were acquired in the offshore domain west of New Caledonia. The northern profile crosses the New Caledonia...
