Abstract
    Carbon dioxide contents and partial pressures were measured during the MAR 93 cruise on several water samples collected from black smoker chimneys and around mussels and shrimps at the Snake Pit (MARK) vent field (Mid-Atlantic Ridge). High end-member values for total CO sub(2) (10.63 mmol l super(-1)) and CO sub(2) partial pressure (335 Torr directly measured at 33 degree C; 1 Torr = 0.133 kPa) were recorded for black smokers samples. Water sampled in close proximity of organisms was found moderately but significantly enriched in carbon dioxide.
