RV Investigator Voyage IN2017_C01 Hydrology Data

This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator research voyage in2017_c01, titled "GAB deep water geological and benthic ecology program." The voyage took place from Hobart (TAS) to Hobart between April 11 and April 28, 2017.Hydrology samples were collected from Niskin bottles sampled at various depths during a Conductivity-Temperature-Depth (CTD) deployment. Parameters analysed were salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite and ammonium. Underway samples were also collected every 12 hours (or once every 24 if a CTD coincided with collection time) for nutrient analysis from the underway system which collects water from 7 m depth and is not filtered. This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart.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2017年第01航次（2017_c01）中，由澳大利亚海洋国家设施（Marine National Facility, MNF）旗下“调查者号”（RV Investigator）研究船执行的“GAB深水地质与底栖生态学计划”航次所采集的水文（Hydrology, HYD）数据。该航次于2017年4月11日至4月28日期间开展，往返于塔斯马尼亚州霍巴特港。水文样品通过温盐深仪（Conductivity-Temperature-Depth, CTD）布放期间，于不同深度使用尼斯金采水器（Niskin bottles）采集获得。本次分析的参数包括盐度、溶解氧、磷酸盐、硅酸盐、硝酸盐与亚硝酸盐总量以及铵盐。此外，每12小时采集一次走航海水样品（若采水时间与CTD布放重合，则改为每24小时采集一次），该走航系统采自7米深度且未经过滤的海水，用于营养盐分析。本数据集已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）观测与分析信息与数据中心（IDC）。有关本数据集的更多详细信息，请参阅航次报告与数据处理报告。
