Observation of the coastal current by an Acoustic Doppler Current Profiler (ADCP) was conducted at the Tsuyazaki Ocean Station of the Research Institute for Applied Mechanics (RIAM), Kyushu University, 2 km offshore of Fukuoka, Japan. The depth of the water is about 15 m at the station and an ADCP was put on the sea bottom in the center of the station. The main interest of the observation was the vertical structure of the coastal current, and the current was measured at about 36 layers of 0.5 m thickness in the vertical plane every hour for 30 days in September 2000. Regular measurement data were provided by the RIAM on wind, tide level, waves and water temperature and the effects of wind current, density current and tidal current on the measured current data are discussed.
