To study comprehensively the marine system in the East Asian region, we are currently extending the prediction model of the Japan/East Sea to the broader northwestern Pacific region. Because we find that tide gauge data improves coastal current significantly, a new gauge is installed at Hegura Island in this summer. Strong sea level changes are found in coastal region of the East China Sea associated with the local wind variation and the river discharge.
