Oceanographic measurements were conducted from Tasmania to Antarctica, and then primarily in the Prydz Bay region, from January 1991 to March 1991. A total of 159 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. Unfortunately, only salinity data from the bottle samples is available due to poor data quality of the nutrient and dissolved oxygen data. CTD salinity data have been calibrated against bottle samples, and are accurate to approximately 0.005 (PSS78). 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
