资源简介：
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.

本次海洋学观测的覆盖范围为从塔斯马尼亚至南极洲海域，1991年1月至3月期间的观测主要集中于普里兹湾（Prydz Bay）区域。本次观测共布设159个温盐深仪（CTD，conductivity, temperature and depth）垂直剖面测站，绝大多数测站的观测深度接近海底。本次采用24瓶式采水器组（rosette sampler）采集海水样本，用于测定盐度、溶解氧、营养盐（磷酸盐、硝酸盐+亚硝酸盐、硅酸盐）、氯氟烃、氦、氚、溶解无机碳、碱度、碳同位素、溶解有机碳、二甲基硫/二甲基巯基丙酸内盐、碘酸盐/碘化物、氧-18、初级生产力以及各类生物学参数。遗憾的是，由于营养盐与溶解氧数据质量不佳，仅采水器样本的盐度数据可用。温盐深仪测得的盐度数据已通过采水器样本校准，其精度约为0.005（PSS78）。本数据集对观测方法与数据处理技术进行了说明，并以图表形式呈现了数据汇总结果。
