A submersible analyzer (Geochemical Anomaly MOnitoring System, GAMOS-IV) powered by micro-diaphragm pumps has been developed for in situ monitoring of time-series changes in manganese concentrations. The analyzer determines dissolved manganese in a continuous manner using a H2O2-luminol chemiluminescence method. The analyzer operates with a sample and reagent flow rate of approximately 60/μl/min, with a detection range up to 10 μM manganese, and has a 98% response time of approximately 6 min. The GAMOS-IV was tested during test deployment at 1,379 m in diffused hydrothermal fields at the Suiyo seamount. The ratio of manganese concentration to temperature (Mn/T) varied with different admixtures of source fluids. Copyright
