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. Also, the sea floor is quite different in time and space scale from the sea surface, but moves slowly and sometimes has a huge impact on our lives. 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, development of seafloor positioning and seafloor topography monitoring system, and ocean information system, 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 ocean renewable energy systems have been conducted at offshore of Hiratsuka city in Sagami-bay, Kuji city of Iwate prefecture, Monbetsu city of Hokkaido government.
