| The objective of this study is to describe the chemical and physical environment surrounding the vent organisms at the Genesis site (EPR, 2640 m). The main chimney is colonized by Riftia pachyptila, fishes Zoarcidae and crabs Bythograeidae. The top of the smoker is covered with tubes of polychaetes Alvinellidae, the frontier zone by limpet gastropods. Temperature measurements and water sampling were made on an axis along the chimney. The environment was characterized using relationships between chemical concentrations and temperature to provide a chemo-thermal model of the site. Discrete temperature ranges were 1-1.6 degrees C in sea water, 1.6-10 degrees C among Riftia plumes (up to 25 degrees C at the tube base), 7-91 degrees C close to the alvinellid... |

| 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... |
