Réseau de surveillance benthique (REBENT) – Région Bretagne. Approche sectorielle subtidale : Identification et caractérisation des habitats benthiques du secteur Morlaix
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ehrhold, Axel; Hamon, Dominique; Chevalier, Claire.
In 2000, Ifremer launched and coordinated the development of a monitoring strategy for the REBENT network (REseau BENThique) in order to assess the aftermath of the “Erika” oil spill which took place in December 1999. Its aim is to provide consistent baseline knowledge on coastal benthic habitats, as well as to develop a monitoring tool that detects changes at various spatial and temporal scales. Sector-based seabed habitat mapping in shallow water (&lt; 50 m deep), is currently being conducted throughout Brittany's coastal waters using a combination of geoacoustic marine systems together with ground-truthing using biological grab sampling and seabed observations. Due to the overlap of soft and rocky bottoms, and contrasting hydrological conditions, the...

Ecologie et cartographie des coraux d’eau froide du canyon de Lacaze-Duthiers en Méditerranée; Données de la campagne CALADU 2019
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sanchez, Pierre; Fabri, Marie-claire.
This work aimed to study populations of cold-water corals in the Lacaze-Duthiers canyon, a French canyon in the western part of the Gulf of Lion. the study was carried out using photos and videos of the wire-Remote Operated Vehicle: the HROV Ariane. Analysis of photos and videos allowed us to obtain information on the general biodiversity, on the spatial and vertical distribution and on the population density of the coldwater coral communities of the canyon but also on the size ranges and of colors of these species. Thus, it was noted that Madrepora oculata was the most represented species. This species has been observed in abundance ten times greater than the Lophelia pertusa species, which presented very dense distributions in places and then almost...
