Supporting Structures

Five species of bresilioid shrimp were investigated at seven hydrothermal sites on the Mid-Atlantic Ridge: Menez Gwen, Lucky Strike, Rainbow, Broken Spur, TAG, Snake Pit and Logatchev. Samples were prepared for analysis of stable isotopes, elemental composition and lipids. Shrimp behaviour was observed from the submersible ‘Alvin’ and in the laboratory aboard RV ‘Atlantis’. The distribution and zonation of the shrimp species was recorded. Juvenile shrimp of all species arrive at the vents carrying reserves of photosynthetic origin, built-up in the pelagic larval stages. These reserves are used while the shrimp metamorphose to the adult form and, in Rimicaris exoculata and Chorocaris chacei, while they develop epibiotic bacteria supporting structures, the modified mouthparts and the inside of the carapace. The main food of adult R. exoculata is filamentous bacteria that grow on these structures. The intermediate sizes of C. chacei also feed on such bacteria, but the final stage gets some food by scavenging or predation. Mirocaris species scavenge diverse sources; they are not trophically dependent on either R. exoculata or mussels. Adults of Alvinocaris markensis are predators of other vent animals, including R. exoculata. The dense swarms of R. exoculata, with their exosymbionts, can be compared to endosymbiont-containing animals such as Bathymodiolus and the vestimentiferan tube-worms of the Pacific vents. Such associations, whether endo- or ectosymbiotic, may be necessary for the development of flourishing communities at hydrothermal vents.

MoMAR-D: a technological challenge to monitor the dynamics of the Lucky Strike vent ecosystem. – ICES Journal of Marine Science, 68: 416–424. The MoMAR (monitoring the Mid-Atlantic Ridge) project was initiated in 1998 by the InterRidge programme to promote and coordinate long-term multidisciplinary monitoring of hydrothermal vents at the Mid-Atlantic Ridge (MAR). The major objective of the project is to study vent ecosystem dynamics using a multidisciplinary approach from geophysics to microbiology over a period of a few decades. MoMAR-D is a demonstration project of MoMAR, partially funded by the European network of excellence ESONET (http://www.esonet-noe.org/). MoMAR-D aims to deploy and manage a multidisciplinary observing system at the Lucky Strike vent field for 1 year. This large hydrothermal field is located at the centre of one of the most volcanically active segments of the MAR. The project has been set up to monitor this region to capture evidence of volcanic events, observe interactions between faulting, magmatism, and hydrothermal circulations, and to evaluate the potential impacts of these environmental factors on the unusual communities colonizing hydrothermal vents. The MoMAR-D infrastructure consists of two sea monitoring nodes (SEAMON) acoustically linked to a surface buoy with satellite communication to a land-based station. The first node will be mainly dedicated to geophysical studies, whereas the second will focus on ecological studies and chemical fluxes. The infrastructure should have been deployed in September 2010 during the MoMARSAT cruise.

Visual Observations

Since the first visual observations of hydrothermal vents in the Eastern Pacific in 1976 (Lonsdale, 1977) these areas of the sea bed have been characterized by their spectacular, and in most cases, novel fauna. Of the 236 macrofaunal species described from hydro-thermal vents, 223 were new to science according to the most recent estimate (Tunniclif f e, 1991), although there are many species still awaiting description. The vent areas are characterized not only by the organisms present but by those which are apparently absent. Absentees include sponges, brachiopods, bryozoans, echiurans and echinoderms, although the last phylum is represented by occasional sightings of echinoids, ophiuroids and holothurians (Grassle, 1986; Tunnicliffe, 1991; Segonzac, 1992).
