The ocean has always been in constant flux. Cause of ocean fluctuation vary : sea surface wind, sea-level pressures, seawater density, and topography. States of oceanic fluctuation are generally represented by flow such as ocean current and tidal current, and waves that express sea surface configuration. Everything in the ocean drifts and oscillates under the influence of waves and flows. Ocean engineering starts from understanding oceanic fluctuation and eventually assesses their influence. Main areas of the laboratory research are measurement of sea surface physical phenomena such as wave, wind, sea level, and sea ice by using microwave pulse Doppler radar, dynamics of floating and underwater line structure, and development of ocean renewable energy systems. Field experiment of remote sensing of sea surface by using microwave radars, and R&D and demonstration of ocean renewable energy utilization systems have been conducted at offshore of Hiratsuka city in Sagami-bay, Namie town of Fukushima prefecture, Kuji city of Iwate prefecture, Monbetsu city of Hokkaido government.
