RV Investigator Voyage IN2018_V03 Hydrology Data

This record describes Hydrology (HYD) data collected collected from the Marine National Facility RV Investigator Voyage IN2018_V03, titled: "Integrated Marine Observing System: monitoring of East Australian Current property transports at 27S." The voyage took place between April 19 and May 10, 2018 departing Brisbane (QLD) and returning to Brisbane.Five nutrients were analysed; silicate, phosphate, nitrate + nitrite, nitrite and ammonium. Certified reference materials for nutrients in seawater were within the specified limits of the certified value.The Guildline salinometers were problematic at sea, samples from CTD 12, 13, 14, the underway thermosalinograph and Triaxus samples were collected in crimped top bottles and brought back to Hobart for analysis.High quality data was produced for the three measured parameters.This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart.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.

本记录描述了澳大利亚国家海洋设施（Marine National Facility）“调查者号”（RV Investigator）IN2018_V03航次采集的水文学（Hydrology，HYD）数据，该航次标题为“综合海洋观测系统：27°S处东澳大利亚洋流属性输运监测”。该航次于2018年4月19日至5月10日期间进行，从布里斯班（昆士兰州，QLD）出发并返回布里斯班。本次分析了五种营养盐：硅酸盐、磷酸盐、硝酸盐+亚硝酸盐、亚硝酸盐及铵盐。海水营养盐的认证参考物质（Certified Reference Materials）结果均在认证值的规定范围内。海上作业期间，Guildline盐度计出现故障，因此温盐深仪（CTD）12、13、14站位、走航温盐仪及Triaxus系统采集的样品均装入压盖瓶带回霍巴特进行分析。所测三个参数的数据集质量优异。本数据集已存档于霍巴特的澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气信息数据中心（O&A Information and Data Centre，IDC）。有关本数据集的更多信息详见航次报告及数据处理报告。
