The Marine Information Research Center (MIRC) and the Japan Oceanographic Data Center (JODC) collect and store about 498,000 serial station data that are mainly observed in the Pacific Ocean by 214 domestic and foreign institutes and 840 vessels since 1906 (Fig. 1).
Using these data, the JODC attempted to take the statistics of temperature and salinity of each standard depth levels in the Pacific Ocean by one-degree squares. However, those statistics have some problems; the zero value which means the missing data or the data which exceeded the standard deviation criteria were often included as the minimum data, because the statistical checks were not performed.
