    Methods:
    Temperature-salinity profiles were obtained with a
    Guildline CTD (8202 Arctic probe, with 8101 deck unit).
    The probe was equipped with a 0-300 dbar pressure transducer.
    The data were recorded to paper chart, and digitized later.
    A Hydrolab TC-2 was used as backup, but the
    temperatures were sometimes below the freezing point.
    Salinities were computed using Perkin-Walker formulae.

    Data Quality:
    These data have undergone a quality control evaluation,
    as per Fissel & Melling (1990).
    Temperature (Guildline) res=0.02, acc=0.03 degC
    Salinity (Guildline) res=0.01, acc=0.02 ppt
    One cast had suspect salinities (ice in cell?).
    The Hydrolab data are of reduced accuracy: 1degC, 1ppt
    Other measurements: Turbidity
