In quality control procedures in oceanic data centers such as JODC (Japan Oceanographic Data Center) and MIRC (Marine Information Research Center), it is impossible to correct archived data without consulting data originators even when erroneous or extraordinary data are found. It is very hard to send all of such data back to the originators. When the data having unbelievable values are found, they would not be eliminated, but some error flags would be attached to them. However, the ultimate purpose of the data management agencies is to collect accurate and correct data as much as possible. We have tried to find error sources in procedure of data processing and data management, in order to improve quality of the data flowing into JODC. In this paper, the results obtained in the analysis on the dataset originating from the Wakayama Research Center of Agriculture, Forestry and Fisheries are reported. Most of the errors are found in the typing or punching processes. Most of the mistakes of this kind can be easily found by using a quality-control (QC) software designed by MIRC. It was found that the data quality of the Wakayama Research Center of Agriculture, Forestry and Fisheries was considerably improved after 1971.
