Summary

Abstract:
Oceanographic measurements were conducted north of Heard Island from August 1993 to October 1993. A total of 58 CTD (conductivity, temperature and depth) vertical profile stations were taken, most to near bottom. Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate), chlorofluorocarbons, helium, tritium, dissolved inorganic carbon, alkalinity, carbon isotopes, dissolved organic carbon, dimethyl sulphide/dimethyl sulphoniopropionate, iodate/iodide, oxygen 18, primary productivity, and biological parameters, using a 24 bottle rosette sampler. CTD salinity data have been calibrated against bottle samples. Upcast CTD burst data were no longer available, howevercomparison of bottle samples to CTD data from the equivalent downcast pressures gives a salinity accuracy ofapproximately 0.005 (PSS78). The bottle data file contains salinities and dissolved oxygens. Nutrient data exist only in files output from the laboratory analysis program &DAPA&, and are contained on floppy disks held by Andrew Forbes (CSIRO). Measurement and data processing techniques are described, and a summary of the data are presented in graphical and tabular form. The fields in this dataset are: oceanography ship station number date start time bottom time finish time cruise start position bottom position finish position maximum position bottom depth pressure temperature (T-90) salinity sigma-T specific volume anomaly geopotential anomaly dissolved oxygen fluorescence photosynthetically active radiation niskin bottle number |
