QUALITY ASSURANCE Data Quality Assurance is a high point of the MTP II-MATER project, at all stages of the data handling:  The data are collected and validated by the scientific laboratories according to internationally agreed standards  Quality checks are performed at the regional data centres before the final archiving, in conformity with IOC and MAST requirements  The results of these checks are transmitted to the scientists in charge of the data sets for cross-checking CIRCULATION OF INFORMATION AND DATA Within one month :  Summary reports for cuises (ROSCOP), moorings and description of the main instruments/methods were made available on the Web Within six month after the field experiment :  Validated data sets corrected from instrumental errors and data reports including documentation on the data collection, processing and validation (EDMED) were sent for archiving to the Regional Data Centre QC0 : Completeness of the information and format QC1 : Automatic and visual checks on date and location QC2 : Automatic and visual checks on the observations
