Partly in Japanese. The study objective is general ocean circulations, in particular shallow circulations such as the Kuroshio Current and deep circulations in the North Pacific, in terms of the kinematic features, variabilities and the roles in formation and distribution of water masses. Development of instruments and methods of ocean measurement. Computer images, Interfaces for hydrographic maps and air-sea interaction maps, Hydrographic map from NOAA Ocean Atlas, Links to other servers of oceanographic data, FAQs on oceanography and meteorology, Cruise reports.

Research fields are tectonic, petrological and paleomagnetic studies of the ocean floor.
Main observational methods are bathymetric swath mapping, geomagnetic survey, rock sampling, ocean drilling, and sea floor observations using submersibles. Research Cruise Report, Research vessels. Earthquake Research Institute, University of Tokyo. Partly in Japanese.
