Hydrodynamic behaviour of Nummulites: implications for depositional models

Large benthic foraminifers are considered to be good indicators of shallow marine carbonate environments in fossil series. Over the last 50 years, the palaeoenvironment of Tertiary Nummulites accumulations has been a matter of debate, particularly be...

Progrès technologiques au sein des industries alimentaires. Impact sur la qualité des produits

This study has been carried out on behalf of the Technology Academy in the framework of a number of works aiming to characterize the impact of the evolution of production and transformation technologies on the sanitary, nutritional and organoleptic q...

Ecology and Distribution of the Malesian Podocarps;Ecology of the Podocarpaceae in Tropical Forests

Podocarp species and genus richness is higher in the Malesian region than anywhere else on earth, with maximum genus richness in New Guinea and New Caledonia and maximum species richness in New Guinea and Borneo. Members of the Podocarpaceae occur ac...

Combining the Biocean database for deep-sea benthic data with the online Ocean Biogeographic Information System

The Biocean database was designed to collate the extremely large volume of data collected from different deep-sea ecosystem studies conducted by Ifremer's department of 'Environnement Profond' (Deep-Sea Environment). This database comes in a 6-applic...

Diet and gut microorganisms of Munidopsis squat lobsters associated with natural woods and mesh-enclosed substrates in the deep South Pacific

Squat lobsters of the deep-sea genus Munidopsis are among the most regularly reported crustaceans associated with deep-sea wood falls. They are often thought to indirectly use these substrates for preying or scavenging wood-associated molluscs or ann...

How accessible are coral reefs to people ? A global assessment based on travel time

The depletion of natural resources has become a major issue in many parts of the world, with the most accessible resources being most at risk. In the terrestrial realm, resource depletion has classically been related to accessibility through road net...

Complément à la liste commentée des oiseaux de Nouvelle-Calédonie

Complement to the list of the birds of New Caledonia. Over the last five years, ten species of birds not previously known on the island have been seen, increasing the number of species/subspecies recorded in New Caledonia to about 192 taxa. Two of th...

The presence of scleractinian corals and their means of adapting to a muddy environment : the "Gail Bank";Proceedings of the sixth international coral...

Some forty species of scleractinian corals live in a particular, very muddy, environmment situated in the South-Western lagoon of New Caledonia between 25 and 30 metres depth. The seabed is caracterised by the topography of ridges valleys and bumps a...

A simple and rapid device for measuring planktonic primary production by in situ sampling, and 14C injection and incubation

A system (LET GO) is described that enables measurements of primary production at sea after #in situ$ incubation, with 14C being injected at depth immediately after enclosure of the sample. Each incubation cell, about 200 ml, is made of two transpare...

Wave forcing and morphological changes of New Caledonia lagoon islets : insights on their possible relations

In the present study, we examine how waves may contribute to the morphological changes of islets in the New Caledonia lagoon. We collected in situ wave data to investigate their characteristics. Three types of waves are identified and quantified: (1)...
