The Data are assembled and checked for quality in REGIONAL QUALIFICATION CENTRES in co-operation with the National Oceanographic Data Centres/Designated National Agencies of the regions
All the data and meta-data that have been reformatted at the common unique MEDATLAS format are checked for quality according to the International recommendations from IOC, MAST and ICES and the MEDAR protocol defined in Task V under the co-ordination of ICES (http://www.ices.dk/).
The quality assurance includes automatic/objective and visual/subjective checks which are performed on each profile separately and grouped by cruises. Two software tools have been developed to perform these tests and assist the operators:
As a result, a quality flag (GTSPP flag scale) is assigned to each numerical value. In case of outlier on recent data sets, the originator is contacted to validate/correct/eliminate the value.
