Appui à la mise en oeuvre de la Directive Cadre Stratégie pour le Milieu Marin - DCSMM ArchiMer
Fabri, Marie-claire; Andral, Bruno.
La Directive Cadre Stratégie pour le Milieu Marin (DCSMM) promeut une approche écosystémique de la gestion des mers et des océans. Face à cet objectif ambitieux et dans le cadre de leur convention signée en 2005, l’Agence de l’Eau Rhône Méditerranée et Corse a demandé à l’Ifremer une analyse de l’application de la DCSMM dans la sous-région Méditerranée occidentale, et de son articulation, notamment avec la Convention de Barcelone et la Directive Cadre sur l'Eau (DCE). Ce soutien vient en complément de celui apporté par l’Ifremer au plan national au Ministère de l’Ecologie, de l’Energie, du Développement Durable des Transports et du Logement dans le périmètre de son expertise auprès de l’Agence de l’Eau. Une analyse des onze descripteurs recommandée par la...

Are spatial variations in the diets of hydrothermal fauna linked to local environmental conditions? ArchiMer
De Busserolles, F.; Sarrazin, Jozee; Gauthier, Olivier; Gelinas, Y.; Fabri, Marie-claire; Sarradin, Pierre-marie; Desbruyeres, Daniel.
Trophic relationships in Bathymodiolus azoricus mussel bed communities on the Tour Eiffel hydrothermal edifice (Lucky Strike) were assessed using delta C-13 and delta N-15 signatures from 14 hydrothermal species. The nutritional basis of B. azoricus was also investigated with delta S-34. Faunal samples and environmental data (temperature, pH, total dissolved sulfide, iron and copper concentrations) were collected from 12 different locations on the edifice. Chemical conditions varied between microhabitats, and were all correlated to temperature. Carbon and nitrogen isotopic results revealed the presence of two, apparently independent, trophic groups. The first was composed of symbiont-bearing fauna (B. azoricus and their associated polychaetes...

Biodiversity patterns, environmental drivers and indicator species on a High-temperature Hydrothermal edifice, mid-Atlantic ridge ArchiMer
Sarrazin, Jozee; Legendre, Pierre; De Busserolles, Fanny; Fabri, Marie-claire; Guilini, Katja; Ivanenko, Viatcheslav N.; Morineaux, Marie; Vanreusel, Ann; Sarradin, Pierre-marie.
Knowledge on quantitative faunal distribution patterns of hydrothermal communities in slow-spreading vent fields is particularly scarce, despite the importance of these ridges in the global mid-ocean system. This study assessed the composition, abundance and diversity of 12 benthic faunal assemblages from various locations on the Eiffel Tower edifice (Lucky Strike vent field, Mid-Atlantic Ridge) and investigated the role of key environmental conditions (temperature, total dissolved iron (TdFe), sulfide (TdS), copper (TdCu) and pH) on the distribution of macro- and meiofaunal species at small spatial scales (< 1 m). There were differences in macro- and meiofaunal community structure between the different sampling locations, separating the hydrothermal...

Biological data extraction from imagery - How far can we go? A case study from the Mid-Atlantic Ridge ArchiMer
Cuvelier, Daphne; De Busserolles, Fanny; Lavaud, Romain; Floc'H, Estelle; Fabri, Marie-claire; Sarradin, Pierre-marie; Sarrazin, Jozee.
In the past few decades, hydrothermal vent research has progressed immensely, resulting in higher-quality samples and long-term studies. With time, scientists are becoming more aware of the impacts of sampling on the faunal communities and are looking for less invasive ways to investigate the vent ecosystems. In this perspective, imagery analysis plays a very important role. With this study, we test which factors can be quantitatively and accurately assessed based on imagery, through comparison with faunal sampling. Twelve instrumented chains were deployed on the Atlantic Eiffel Tower hydrothermal edifice and the corresponding study sites were subsequently sampled. Discrete, quantitative samples were compared to the imagery recorded during the experiment....

Cold-seep assemblages on a giant pockmark off West Africa: spatial patterns and environmental control ArchiMer
Olu, Karine; Caprais, Jean-claude; Fifis, Alexis; Fabri, Marie-claire; Galeron, Joelle; Budzinsky, H; Le Menach, K; Khripounoff, Alexis; Ondreas, Helene; Sibuet, Myriam.
A giant pockmark colonised by dense cold-seep assemblages near 3160 m depth along the Congo-Angola margin has been surveyed by the ROV Victor 6000. The quantitative distribution of chemosynthetic communities was mapped along the dive tracks from a video study using GIS and image mosaicking. Several types of faunal assemblages, either dominated by bivalves of the families Mytilidae (Bathmodiolus sp.) Vesicom idae (Calyptogena sp., 'Vesicomya' aff. chuni), or by Siboglinidae polychaetes (Escarpia southwardae) were mapped over the 800-m diameter pockmark area and sampled for fauna, water and sediment. The isotopic analyses (delta C-13) of tissues from symbiont-bearing species were within the range typical of nutrition via symbiosis using methane for mussels...

Cold-water coral ecosystems in Cassidaigne Canyon: An assessment of their environmental living conditions ArchiMer
Fabri, Marie-claire; Bargain, Annaelle; Pairaud, Ivane; Pedel, Laura; Taupier-letage, I..
The Cassidaigne canyon is one of the two canyons (together with Lacaze-Duthiers) of the French Mediterranean coast in which cold-water corals have settled and formed large colonies, providing a structural habitat for other species. Nevertheless, the communities settled in the Cassidaigne canyon are physically impacted by discharges of bauxite residues. New information on the distribution of the species Madrepora oculata and the associated species diversity in Cassidaigne canyon was provided by videos and photos acquired in 2013. An area investigated at 515 m depth harbored a high density of small colonies of M. oculata. The water column structure of the area was described by using a CTD transect deployed along the axis of the canyon. High resolution (10 m...

Combining the Biocean database for deep-sea benthic data with the online Ocean Biogeographic Information System ArchiMer
Fabri, Marie-claire; Galeron, Joelle; Larour, Michel; Maudire, Gilbert.
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-application package: 2 of them are used on research vessels to collect operational data, whereas the others are used to link with a core database back on land. The latter are used to: (1) manage taxonomic nomenclature, (2) monitor the identification of faunal collections, (3) fill in chemical analyses results or measurement data files and (4) add or extract data from the database. Biocean was designed to facilitate ecosystem studies in the deep sea. It represents an important new resource for deep-sea ecologists and...

Community dynamics over a decadal scale at Logatchev, 14 degrees 45 ' N, Mid-Atlantic Ridge ArchiMer
Gebruk, Andrey; Fabri, Marie-claire; Briand, Patrick; Desbruyeres, Daniel.
Hydrothermal vent community dynamics over a ten year span was studied in the Logatchev area, 14 degrees 45'N on the Mid-Atlantic Ridge. On the SERPENTINE cruise in March 2007 with the RN Pourquoi pas? and the ROV Victor 6000 (IFREMER), composition, abundance and distribution of dominant megafauna at Logatchev were examined and compared to published data from 1997. Our results revealed notable changes in several community characteristics. The most significant changes evident in March 2007 compared to July 1997 were the increase up to by order of magnitude in the population density of predatory gastropods Phymorchynchus spp. at the site Irina-2 and disappearance of a live population of vesicomyids at the site Anya's Garden. Other notable differences between...

The composition, biomass and diversity of the fauna in a Bathymodiolus thermophilus mussel assemblage colonizing diffuse flow areas on the SEPR is described and compared with biological characteristics of other hydrothermal assemblages. The spatio-temporal dynamics of temperatures over fine scales within the mussel habitat are characterized using newly-developed statistical approaches. Temperature data obtained from two adjacent habitats (a cirriped assemblage and a bare substratum) are compared. The results of the temperature data show that the mean temperature and the temperature variations were significantly higher in the mussel assemblage (mean temperature: 4.12 +/- 1.85 degrees C) in comparison with 2.40 +/- 0.14 degrees C in the cirriped assemblage...
