Biogeography, biodiversity and fluid dependence of deep-sea cold-seep communities at active and passive margins
Abstract To date, several cold-seep areas which fuel chemosynthesis-based benthic communities have been explored, mainly by deployment of manned submersibles. They are located in the Atlantic and inExpand

Cold seep communities in the deep eastern Mediterranean Sea : composition, symbiosis and spatial distribution on mud volcanoes
Two mud volcano fields were explored during the French–Dutch MEDINAUT cruise (1998) with the submersible NAUTILE, one south of Crete along the Mediteranean Ridge at about 2000 m depth (Olimpi mudExpand

Deep-Sea Biodiversity in the Mediterranean Sea: The Known, the Unknown, and the Unknowable
Deep-sea ecosystems represent the largest biome of the global biosphere, but knowledge of their biodiversity is still scant. The Mediterranean basin has been proposed as a hot spot of terrestrial andExpand

Cold seep communities as indicators of fluid expulsion patterns through mud volcanoes seaward of the Barbados accretionary prism
Cold seep communities are sustained by massive methane-rich fluid expulsion through mud volcanoes located at about 5000 m in the Barbados Trench. These communities, dependent on chemosyntheticExpand

Long-term change in the megabenthos of the Porcupine Abyssal Plain (NE Atlantic)
A radical change in the abundance of invertebrate megafauna on the Porcupine Abyssal Plain is reported over a period of 10 years (1989–1999). Actiniarians, annelids, pycnogonids, tunicates,Expand

Dual Symbiosis in a Bathymodiolus sp. Mussel from a Methane Seep on the Gabon Continental Margin (Southeast Atlantic): 16S rRNA Phylogeny and Distribution of the Symbionts in Gills
ABSTRACT Deep-sea mussels of the genus Bathymodiolus (Bivalvia: Mytilidae) harbor symbiotic bacteria in their gills and are among the dominant invertebrate species at cold seeps and hydrothermalExpand

Cold-seep assemblages on a giant pockmark off West Africa: spatial patterns and environmental control
A giant pockmark colonised by dense cold-seep assemblages near 3160 m depth along the CongoAngola margin has been surveyed by the ROV Victor 6000. The quantitative distribution of chemosyntheticExpand

Understanding continental margin biodiversity: a new imperative.
Until recently, the deep continental margins (200-4,000 m) were perceived as monotonous mud slopes of limited ecological or environmental concern. Progress in seafloor mapping and direct observationExpand

ROV study of a giant pockmark on the Gabon continental margin
A giant, 800-m wide pockmark, called Regab, was discovered along the Equatorial African margin at 3160-m water depth and was explored by remote operated vehicle (ROV) as part of the ZaiangoExpand

Diversity, relative abundance and metabolic potential of bacterial endosymbionts in three Bathymodiolus mussel species from cold seeps in the Gulf of Mexico.
Cold seeps in the Gulf of Mexico are often dominated by mussels of the genus Bathymodiolus that harbour symbiotic bacteria in their gills. In this study, we analysed symbiont diversity, abundance andExpand
