Abstract
The Japan Oceanographic Data Center has been submitting oceanographic data to the World Data Center for Oceanography through the framework of the International Oceanographic Data and Information Exchange Committee sponsored by the UNESCO/IOC. In the World Ocean Database 2009, which is the compiled database of the WDC for Oceanography, the Japanese contribution has reached about 16% of the total. Japan is one of the main data suppliers for the WDC for Oceanography. JODC would like to continue to contribute to the World Data System with the WDC.
