  • Preliminary data set contains details of cores processed (eg. sample name/interval, dry weights, reactions, notes) and the methodology used. The future data set will document diatoms observed and counted for each sample. This project also has links to ASAC project 1044 (ASAC_1044), the Wilkes Land Glacial History (WEGA) project. WEGA cores from both the continental shelf (PC7,11,12) and slope (PC19, 20, 21) region have been silica-selectively processed for their diatom content (see methodology file for details). The slides are mounted for quantitative assessment. Details of the cores that have been prepared are listed in the file WEGA_cores.csv in the downloadable dataset. Additional silica-selective slides of the surface sediments on the continental shelf were processed for quantitative assessment. Details of the samples and their locations are listed in the file sediment_samples.csv in the downloadable dataset. There have been no publications from the prepared slides as of the 15/04/02. An unpublished Honours Thesis uses limited diatom counts from slides prepared from PC 12. (Ms J. Erbs 2001). Title to be forthcoming. Any further enquiries referring to sample availability, curation, additional samples or publications arising from this material should be directed to Dr L. Armand.

  • 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.

  • Oceanographic measurements were conducted in the Southern Ocean around Heard and McDonald Islands, and in the Prydz Bay region, from January 1992 to March 1992. 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.
