| Outline of Final Research Achievements |
It has been succeeded to ignite reproducible micro-discharge plasma by applying pulse current using an impulse generator circuit to pin-to-plate electrodes in sea water (artificial sea water: 10ASW and natural deep sea water sampled at Muroto) and to observe optical emission spectra from the plasma. To assign the emission peaks in the spectra to each elements, micro-discharge and optical emission spectroscopy was carried out also for each solution of ingredient in 10ASW. In the emission spectra from plasma of sea water, emission peaks from composition elements and contaminants from electrodes were found.
