AB: Particularly after the advent of the multi-beam echosounders (aka, swath mapping system), accumulation of high- resolution bathymetric data invoked tremendous impact on marine sciences worldwide. In the last two decades with rapid improvements of the swath-mapping technologies, our knowledge and view of the seafloor made great advancement. Japan as a coastal state has also been conducting quite extensive and intensive "Continental Shelf Survey" for many years now and has benefited from the swath mapping technology as well. Japanese EEZ covers wide area of the northwestern Pacific and shares borders with tectonically complex and scientifically challenged neighboring regions. The "Continental Shelf Survey" of Japan is a multi-institutional effort by private, academic and governmental sectors, administered by the government. Huge amounts of marine geological, geophysical and bathymetric data are still being collected, compiled and analyzed at each sector who has its responsibility and priority, so the full access to the compiled scientific data or the disclosure of the data to science community would take some more time in future. But the parts of scientific results and data have been presented and published as they come out, at the meetings and in journals, which is also the policy of the administering government. Eyes only preview of the ongoing compiled data is not prohibited, so the international scientific cooperation discussion, for example, could be started earlier and the session like this is a best opportunity for marine scientists to be aware of what we have and what we should have for regional/global sciences to the next step, which are generally costly pursued separately. I will present and discuss on the compiled bathymetric map of the northwestern Pacific together with geophysical data or meta-data in the same region, e.g. gravity, magnetic and seismic data compiled.
