Oceanographic measurements were conducted between Tasmania and Heard Island, and then around Heard and McDonald Islands from May to July 1990. A total of 96 CTD (conductivity, temperature and depth) vertical profile stations were taken, most to near bottom. No Niskin bottle water data are available unfortunately (for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate), dissolved inorganic carbon, alkalinity, carbon isotopes, primary productivity, and biological parameters. Measurement and data processing techniques are summarised, and a summary of the data are presented in graphical and tabular form.
The fields in this dataset are:
