New Caledonia Lagoon : a threatened paradise under anthropogenic pressure ?;Lagoons : habitat and species, human impacts and ecological effects

The French archipelago of New Caledonia hosts one of the three most extensive reef systems in the world and was partly added to the UNESCO World Heritage List in 2008. In the very specific context of rapidly growing land-based mining extraction and o...

Impacts of shrimp farm effluent on water quality, benthic metabolism and N-dynamics in a mangrove forest (New Caledonia)

Water quality parameters, sediment oxygen demand (SOD), dissolved organic and inorganic nutrient fluxes, and N-cycle processes (nitrification; denitrification; dissimilatory nitrate reduction to ammonium (DNRA)) were determined in a New Caledonian ma...

Données économiques maritimes françaises 1998

The purpose of this book is to value the economic significance of marine-related activities in France. Each industrial, or public non-commercial, sector is characterized by key figures relating to annual turnover, value added, employment and budget. ...

Bathymay : la structure sous-marine de Mayotte révélée par l'imagerie multifaisceaux

La campagne Bathymay, effectuée en 2004 à bord du N/O Marion Dufresne 2 , a permis de réaliser le premier levé bathymétrique complet de la pente insulaire de Mayotte. L'analyse préliminaire de la morphologie révèle l'existence de nombreux can...

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...

Considering reefscape configuration and composition in biophysical models advance seascape genetics

Previous seascape genetics studies have emphasized the role of ocean currents and geographic distances to explain the genetic structure of marine species, but the role of benthic habitat has been more rarely considered. Here, we compared the populati...

Fisheries in the Pacific : the challenges of governance and sustainability

"Fisheries in the Pacific : The Challenges of Governance and Sustainability" is a multidisciplinary book, which examines various aspects of coastal and oceanic fisheries in Pacific waters. These interrelated fisheries sectors are critical for regiona...

Contrasted ecological niches shape fungal and prokaryotic community structure in mangroves sediments

Mangroves are forest ecosystems located at the interface between land and sea where sediments presented a variety of contrasted environmental conditions (i.e. oxic/anoxic, non-sulfidic/sulfidic, organic matter content) providing an ideal ecosystem to...
