    • Thermodynamic calculations with the program PHREEQE (12) indicate that seawater is undersaturated with respect to brucite, in contrast to supersaturation of brucite, talc, and serpentine for mixing of seawater with the range of vent fluid compositions reported by (1).

    • 14C values of -32.2 and -67.9 at depths of 686 and 1076, respectively, and correspond to reservoir ages of 268 and 565 years, respectively. The young ages of the active vents suggest that bomb radiocarbon has penetrated deeper into the water column and that the vents must be fed by relatively shallow water masses. If recharge of the hydrothermal system was deep water, ages of at least 830 years (reservoir age at ∼30°N) would be obtained.
