Quality control of data is an essential component of oceanographic data management. Data quality control information tells users of the data how it was gathered, how it was checked, processed, what algorithms have been used, what errors were found, and how the errors have been corrected or flagged. Without it data from different sources cannot be combined or re-used to gain the advantages of integration, synthesis, and the development of long time series.
