Metabolic energies available from the aerobic and anaerobic reactions shown in Table 1 . Calculations were performed for all the 89 hydrothermal vent sites in MOR-B, MOR-U, AMA-M, ABA-F, SED-MOR, and SED-ABA settings. Shaded areas represent hydrothermal vents issuing highly vapor-rich (<100 mmol/kg Cl) fluids.
