RV Investigator Voyage IN2018_V01 Hydrology Data

This record describes Hydrology (HYD) data collected collected from the Marine National Facility RV Investigator Voyage IN2018_V01, titled: "Detecting Southern Ocean change from repeat hydrography, deep Argo and trace element biogeochemistry & CAPRICORN." The voyage took place between January 11 and February 21, 2018 departing from Hobart (TAS) and arriving in Hobart.Five nutrients were analysed; silicate, phosphate, nitrate + nitrite, nitrite and ammonium. This was the first time ammonium has been measured successfully on every station for a hydrographic voyage.High quality data was produced for the three measured parameters. Certified reference materials for nutrients in seawater were within the specified limits of the certified value.This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart.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.

本数据集记录了采集自澳大利亚国家海洋设施（Marine National Facility）“调查者号”（RV Investigator）航次IN2018_V01的水文（Hydrology, HYD）数据，航次主题为“基于重复水文调查、深层Argo浮标与痕量元素生物地球化学及CAPRICORN计划探究南大洋变化”。该航次于2018年1月11日至2月21日执行，从霍巴特（塔斯马尼亚州，TAS）出发并最终返回霍巴特。本次航次共分析了五类营养盐组分：硅酸盐、磷酸盐、硝酸盐+亚硝酸盐、亚硝酸盐与铵盐。本航次首次实现了在所有调查站位均成功完成铵盐含量的测定。三项测定参数均产出了高质量数据，海水营养盐认证参考物质的测定结果均处于认证值的允许偏差范围内。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（Commonwealth Scientific and Industrial Research Organisation, CSIRO）观测与分析信息与数据中心（IDC）。有关本数据集的更多补充信息可参阅航次报告与数据处理报告。
