     East China Sea and the Philippine Sea in summer.
     * An observation of marine pollutant to monitor background of marine poliution.
     * Oceanographical and maritime meteorological observations for the verification of
     buoy robot observation.
     * Verification of ocean wave forecast.
     * Improvement of the quality on the sea condition forecast and warning. 
     * Watch the heavy rain associated with Baiu front for forecast and warning.
