i*.dat (Files 13-21)

These files,i08si09s.dat, i09n.dat, i08ni05e.dat, i03.dat, i05wi04.dat, i07n.dat, i01.dat, i10.dat, and i02.dat, provide hydrographic, carbon dioxide, and chemical data for all stations occupied during the R/V Knorr cruises along WOCE Sections I8SI9S, I9N, I8NI5E, I3, I5WI4, I7N, I1, I10, and I2. Each line consists of station number, cast number, sample number, bottle number, CTD pressure, CTD temperature, CTD salinity, CTD oxygen, potential temperature, bottle salinity, bottle oxygen, silicate, nitrate, nitrite, phosphate, CFC-11, CFC-12, TCO₂, TALK, 14C, 14C error, 13C, and data-quality flags. The files are sorted by station number and pressure and can be read by using the following FORTRAN 90 code [contained in IOstainv.for ( File 3)]:

    qualt          15-digit character variable that contains data-quality flag codes for
                   parameters underlined with asterisks (*******) in the file header
    _________________________________
    *Variables that are underlined with asterisks in the data file's header indicate they have a data-
    quality flag.  Data-quality flags are defined as follows:

        1     = sample for this measurement was drawn from water bottle but analysis was
                not received
        2     = acceptable measurement
        3     = questionable measurement
        4     = bad measurement
        5     = not reported
        6     = mean of replicate measurements
        7     = manual chromatographic peak measurement
        8     = irregular digital chromatographic peak integration
        9     = sample not drawn for this measurement from this bottle
