Micro-plasma discharge in sea water and optical emission spectroscopy were carried out for possible application to in-situ analysis on elemental composition in sea water. A current pulse was supplied to a micro-gap between pin-to-plate electrodes. A spark discharge plasma was generated and some dominant elements were detected in the emission spectrum.
