| Twelve species of recent brachiopods belonging to the genera Lingula, Discradisca, Novocrania, Xenobrochus, Eucalathis, Frenulina, Argyrotheca, Campages, Thecidellina and Lacazella were identified in samples collected during shallow-water cruises around New Caledonia, southwest Pacific. Six genera, Lingula, Xenobrochus, Eucalathis, Frenulina, Campages and Thecidellina, have been already reported from the New Caledonian region, while four genera, Discradisca, Novocrania, Argyrotheca and Lacazella are the first records from this region. Additionally, Discradisca stella is the first discinid brachiopod recognized in the New Caledonia area. One new species is described, the megathyridid Argyrotheca neocaledonensis n. sp. The biogeographical affinities of the... |

| The eastern lagoon of New Caledonia (NC, Southwest Pacific), listed as a UNESCO World Heritage site, hosts the world's second longest double-barrier coral reef. This lagoon receives river inputs, oceanic water arrivals, and erosion pressure from ultramafic rocks, enriched in nickel (Ni) and cobalt (Co). The aim of this study was to characterize colored dissolved organic matter (CDOM), as well as to determine its main sources and its possible relationships (through the use of Pearson correlation coefficients, r) with biogeochemical parameters, plankton communities and trace metals in the NC eastern lagoon. Water samples were collected in March 2016 along a series of river/lagoon/open-ocean transects. The absorption coefficient at 350 nm (a(350)) revealed... |

| High-resolution reflection and refraction seismic data were collected in 2004 to investigate, in further detail than allowed by pre-existing low resolution seismic data, the nature of a Bottom Simulating Reflector (BSR) that extends over a broad area of the Fairway Basin, a rifted, continental structure located on the eastern flank of the Lord Howe Rise, to the southwest of New Caledonia. Two main reflectors are documented: the shallower (RN) mimics the seafloor and has a negative polarity while the deeper (RP) does not always mimic the seafloor and has a positive polarity. Using the existing regional seismic lines, we can show that reflector RN can be continuously followed up to DSDP 208 drill hole site. Reflector RP is discontinuous and cannot be traced... |

| The ZoNeCo programme, devoted to the evaluation of living and non-living marine resources within the Economic Zone of New Caledonia, illustrates clearly the Marine Benthic Habitats concept. It exhibits the study of the physical environment and disciplines such as geology and physical oceanography. The results acquired in these fields are used as bases to study the presence and the distribution of living species within a given habitat. The knowledge of all the parameters relative to each discipline is a useful guide for the evaluation and the sustainable management of living and nonliving resources. |

| The Fairway Ridge is a buried continental structure that separates the Fairway Basin from the New Caledonia Basin. The proposed Cretaceous age of the Fairway Basin has remained highly hypothetical to date. Deep offshore petroleum exploration wells revealed well-dated Mesozoic carbonaceous sedimentary rocks in the Taranaki Basin at the southern end of the Aotea Basin. In this paper we use geophysical data to confirm the continuity of the 2000 km long Fairway-Aotea Basin connecting New Caledonia to New Zealand and prove its early Late Cretaceous age. Analysis of seismic reflection profiles together with newly compiled gravity and magnetic maps reveals Late Cretaceous NESW trending lineaments projecting northeastward from major Tasman Sea fracture zones and... |

| In the Southwest Pacific Ocean, waters transit from the subtropical gyre before being redistributed equatorward and poleward. While the mean pathways are known, the contribution to the mixing and transport of the water from mesoscale eddies has not been comprehensively investigated. In this research, satellite altimetry data, combined with an eddy detection and tracking algorithm is used to investigate the distribution and surface characteristics of mesoscale eddies in this region of complex bathymetry (10 degrees S-30 degrees S, 140 degrees E-190 degrees E). Detected eddies are then colocalized with in situ data from Argo floats to determine their vertical structure and the effect of eddies on the water masses. The numerous islands affect the eddy... |

| The genus Pseudolatirus Bellardi, 1884, with the Miocene type species Fusus bilineatus Hornes, 1853, has been used for 13 Miocene to Early Pleistocene fossil species and eight Recent species and has traditionally been placed in the fasciolariid subfamily Peristerniinae Tryon, 1880. Although the fossil species are apparently peristerniines, the Recent species were in their majority suspected to be most closely related to Granulifusus Kuroda & Habe, 1954 in the subfamily Fusininae Wrigley, 1927. Their close affinity was confirmed by the molecular phylogenetic analysis of Couto et al. (2016). In the molecular phylogenetic section we present a more detailed analysis of the relationships of 10 Recent Pseudolatirus-like species, erect two new fusinine... |
