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...

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...

Rapid and sensitive PCR detection of Vibrio penaeicida, the putative etiological agent of syndrome 93 in New Caledonia

Experimental infections of Penaeus (Litopenaeus) stylirostris were performed with a Vibrio penaeicida strain (AM101) isolated in New Caledonia from Syndrome 93 diseased shrimp. Cumulative mortalities resulting from intramuscular injection or immersio...

Penaeid reared brood stock : closing the cycle

Three shrimp species, Penaeus monodon, P. stylirostris (Panama and Mexican strains) and P. vannamei have matured and spawned in captivity at the Centre Océanologique du Pacifique (COP) laboratory. The shrimp, originally stocked as juveniles or postl...

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...

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...

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...

Orama nui : a programme for an observatory of marine resources and activities in the Pacific Islands Countries

The "ORAMA NUI" programme has been developed by the Territory of French Polynesia and IFREMER, both partners in SPT since 1988. It first aims at alleviating some bottlenecks, mainly in the coastal and lagoon economic development process, by use of sa...

Observer, évaluer et suivre la biodiversité sous marine des lagons : Intérêt des techniques vidéo rotatives en haute dé:nition. Où en est-on en...

This article first draws up a balance sheet of all various implemented techniques to observe and monitor the shallow marine biodiversity. Then the article focuses on the techniques of the rotating high resolution submarine video and their implementat...

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...
