Data Management

JODC receives data observed by Japan Coast Guard, Meteorological Agency, Fisheries Agency and other organizations including Defense Agency, local government agencies, universities, and private industries. JODC also acquires foreign data through the international oceanographic data and information exchange system (IODE)

Collecting/Processing/Archiving/Providing

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 oceanophysical, hydrophysical 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 standard JODC archive format. Data in these files are available as copies of specified data subsets on magnetic tapes, floppy disks, CD-ROMs or printed form.

Digital Data Holdings at JODC

The collected digital data at JODC are converted onto 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 with sort in order of cruise or geography.
The follow provides descriptions of each JODC's Master Data File. The data file description includes a file format designed by JODC.

Temperature and Salinity

• Serial Station Data
• STD/CTD Data (Serial Station Data Format)
• CTD Data
• BT Data
• Statistics of Temperature in 1 degree Mesh
• Statistics of Salinity in 1 degree Mesh

Ocean Current

• Ocean Surface Current Data
• Shipboard ADCP Data
• Statistics of Ocean Current in 1 degree Mesh

Tide (Sea Level)

• Sea Level Data

Tidal Current

• Mooring Observation Data

Marine Pollution

• MGD77 Data (Bathymetry, Geomagnetism, Gravity)
• J-BIRD (JODC Bathymetry Integrated Random Dataset)

Marine Biology

• Marine Organisms Data

Non-Digital Data (Microfilm/Microfiche)

Beside 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 were included.
