JODC receives data observed by Japan Coast Guard, Meteorological Agency, Fisheries Agency and other organizations including Ministry of Defense, local government agencies, universities, and private industries. JODC also acquires foreign data through the International Oceanographic Data and Information Exchange (IODE).
JODC receives worldwide physical-chemical oceanographic data from government agencies, academic institutes, and other organizations in Japan as well as from international joint projects. JODC's data holdings provide global coverage of basic oceanographical, hydrographical properties such as temperature, salinity, ocean current, tide, tidal current, geomagnetism, gravity and bathymetry. JODC's Master Data Files hold numerous individual data submissions that undergo JODC quality control procedures and are stored in the standard JODC archives format. Data in these files are available as copies of specified data subsets on magnetic tapes, floppy disks, CD-ROMs or printed form.
The collected digital data at JODC are converted into JODC format and the data
on the printed sheet or analogue record are digitized at JODC. Those data are
stored in the file by instrument or by data type sorting by cruise or geography.
The followings provide descriptions of each JODC Master Data File. The data file description includes the file format designed by JODC.
|Ocean Current Data|
|Tide (Sea Level)|
|Bathymetry and Marine Geology|
Besides providing copies of data or listings of data from the master file, JODC also provides users with copies of microfilm or microfiche in which statistical analyses, sea level observation records, tidal constituents, plotting sheets, aged charts, hydrographic publications, etc are included.
