Aurora Australis SAZ Southern Ocean oceanographic data, cruise au97_9806

Oceanographic measurements were conducted in the Subantarctic Zone south of Tasmania in March 1998. A total of 97 CTD vertical profiles were taken. Over 800 Niskin bottle water samples were collected for the measurement of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite, silicate), dissolved inorganic carbon, alkalinity, carbon isotopes, dissolved organic carbon, N2O isotopes, pH, oxygen-18, barium, nitrogen-15, arsenic, ammonia, DMS/P, bacteria, silicon-32, particulate silicon, productivity, ETS, pigments, species counts, cytometry, particulate organic carbon and nitrogen, urea, copper and iron, using a 24 bottle rosette sampler. Four sediment trap moorings were recovered, and two were redeployed.

1998年3月，研究团队于塔斯马尼亚以南的亚南极带（Subantarctic Zone）开展海洋学观测作业。本次作业共获取97条CTD（温盐深）垂直剖面数据；采用24瓶式罗塞特采水器（rosette sampler），通过尼斯金采水器（Niskin bottle）采集了800余件水样，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）、溶解无机碳、碱度、碳同位素、溶解有机碳、一氧化二氮同位素、pH、氧-18、钡、氮-15、砷、氨、DMS/P、细菌、硅-32、颗粒硅、海洋初级生产力、电子传递系统（ETS）、色素、物种计数、细胞计数分析、颗粒有机碳与氮、尿素、铜及铁等多项指标。本次作业共回收4套沉积物捕集器锚系装置，其中2套完成重新部署。
