Abstract :
An in situ chemical sensor system has been developed owing to a continuous effort involving lab and field-testing over the past ten years. The sensor has been used successfully to simultaneously measure pH, dissolved H2, and dissolved H2S concentrations in seafloor hot spring fluids at temperature and pressure conditions up to 380degC and 250 bars. The sensor system is particularly well suited for deployment with DSV Alvin and has now been used for real-time geochemical studies of vent fluids at the East Pacific Rise
