A total of 168 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, although the calibration quality varies over the cruise. CTD salinity accuracies can be summarised as follows: Stations 1-26: no bottle samples; conductivity calibration from later stations applied; accuracy therefore unknown. Stations 27-102: accuracy approximately 0.005 (PSS78). Stations 83-93: residuals a bit lower than surrounding stations: data uncertainty may be slightly increased. Stations 103-111: no bottle samples; conductivity calibration from surrounding stations applied; accuracy therefore unknown. Stations 112-168: significant increase in data scatter; accuracy approximately 0.010 (PSS78). The bottle data file contains salinities and nutrients. Dissolved oxygen data exist only as titration values recorded on the laboratory analysis sheets. The nutrient data show a fair amount of scatter, particularly when looking at the nitrate vs phosphate ratios. These data should be used with caution. Measurement and data processing techniques are described, and a summary of the data are presented in graphical and tabular form.

Weather conditions were generally moderate, and there were few scientific equipment failures, allowing complete coverage of the areas surveyed. The oceanography program took place in three regions; Heard Island, the eastern flank of the Kerguelen Plateau, and Prydz Bay. Each region had specific objectives, please see the reference given above for these. 61 CTD stations were completed in the Heard Island region, and several XBT's were dropped between widely spaced stations. A number of XBT's were deployed between Heard Island and the Kerguelen Plateau section. The CTD section consisted of 14 CTD casts to the bottom, the deepest being 4850m. XBT's were deployed between the Kerguelen Plateau section and Prydz Bay. 93 CTD stations were occupied in the Prydz Bay region. 40 XBT's were dropped in the transit from Casey to Hobart.

CTD salinity data have been calibrated against bottle samples, although the calibration quality varies over the cruise. CTD salinity accuracies can be summarised as follows: Stations 1-26: no bottle samples; conductivity calibration from later stations applied; accuracy therefore unknown. Stations 27-102: accuracy approximately 0.005 (PSS78). Stations 83-93: residuals a bit lower than surrounding stations: data uncertainty may be slightly increased.
