*DATASET - NAME: Dissolved Chlorofluorocarbons in water column - Inorganic Chemistry.
*CENTRE - NAME: Hellenic National Oceanographic Data Centre (HNODC), National Centre for Marine Research (NCMR)
*TIME - PERIOD: 12 October - 9 November 1998.
*GEOGRAPHIC - COVERAGE: Adriatic Basin and Ionian Basin.
*PROJECT: MASTIII/MTPII - MATER.
*PARAMETERS: Pressure, Temperature, Salinity, Dissolved CFC11, Dissolved CFC12, Dissolved CFC113 and
and quality flags.
*INSTRUMENTS: Gas chromatograph with capillary column and electron capture detector.
*SUMMARY: Offline CFC sampling: 100 ml of sea water are filled into glas ampoules which are flame-sealed with a CFC-free nitrogen headspace. In the laboratory at Bremen are measured with a fully automated gas chromatographic system. The basic design of system consists of a capillary column combined with a low volume trap to achieve full separation of peaks and high resolution. 30 ml of the sample are analyzed. The system is standardly calibrated against gas standards. All concentrations are referenced against the SIO93 scale. Individual errors have been assigned to each measurement. The quality digit assigned to each measurement contains information about the data quality 2=good measurement, 3=questionable measurement, 4=bad measurement, 6=replicate sample.
Volume/Number of Profiles: 160 CFC-values/19 profiles
