RV Investigator Voyage IN2023_V03 Hydrology Data

This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2023_V03, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania." The voyage took place between May 11, 2023 and May 25, 2023 (AEST), departing from Hobart and returning to Hobart.

Hydrology samples were collected from Niskin bottles sampled at various depths during Conductivity-Temperature-Depth (CTD) deployments. Parameters analysed were salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite and ammonium.

This dataset has been processed (quality-controlled), and archived at the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset is contained in the Voyage Report and Data Processing Report.

本记录描述了从海洋国家设施（Marine National Facility, MNF）“调查号”（RV Investigator）航次IN2023_V03获取的水文（Hydrology, HYD）数据，该航次的项目标题为："SOTS：塔斯马尼亚西南海域用于气候与碳循环研究的南大洋时间序列自主锚泊系统"。本次航次于2023年5月11日至2023年5月25日（澳大利亚东部标准时间，AEST）执行，从霍巴特出发并返回霍巴特。

水文样品通过温盐深剖面仪（Conductivity-Temperature-Depth, CTD）布放期间，在不同深度使用尼斯金采水器（Niskin bottles）采集。本次分析的参数包括盐度、溶解氧、磷酸盐、硅酸盐、硝酸盐+亚硝酸盐以及铵盐。

本数据集已完成处理（质量控制），并存档于位于霍巴特的澳大利亚联邦科学与工业研究组织（CSIRO）国家馆藏与海洋基础设施（National Collections and Marine Infrastructure, NCMI）信息与数据中心（Information and Data Centre, IDC）。有关本数据集的更多信息详见航次报告与数据处理报告。
