Abstract
    Water samples were collected by titanium syringe samplers from Beehive and Moose vent fields in the Snake Pit area during the MAR 93 cruise. This set comprised samples obtained from black smokers as well as from sites within the most common animal communities present in the Snake Pit area, i.e. beds of musssels of the genus Bathymodiolus and swarms of the shrimp Rimicaris exoculata. Thus, these samples were expected to involve various degrees of mixing of hot vent water and cold bottom water. P sub(C02) and C0 sub(2) values measured in samples taken in close proximity of vent organisms, mussels and shrimps, also revealed an albeit modest C0 sub(2) enrichment, reaching values at about 2 Torr. This may probably be beneficial in providing inorganic carbon to chemoautotrophic symbioses but also might require specific physiological adaptations for such organisms.
