RV Investigator Voyage IN2023_V05 Hydrology Data

This record describes the End of Voyage (EOV) data archive from the Marine National Facility (MNF) RV Investigator voyage IN2023_V05, titled "Untangling the causes of change over 25 years in the southeast marine ecosystem (SEA-MES Voyage 1)." The voyage took place between June 27, 2023 and July 29, 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.

本记录描述了海洋国家设施（Marine National Facility，MNF）旗下RV Investigator号研究船IN2023_V05航次的航次结束（End of Voyage，EOV）数据档案，该航次标题为“解析东南海洋生态系统25年变化成因（SEA-MES航次1）”。本航次于澳大利亚东部标准时间（AEST）2023年6月27日至2023年7月29日执行，起航及返航港口均为霍巴特。在电导率-温度-深度剖面仪（Conductivity-Temperature-Depth，CTD）布放作业期间，通过尼斯金采水器（Niskin bottles）于不同深度采集了水文样本；本次分析的参数包括盐度、溶解氧、磷酸盐、硅酸盐、硝酸盐及亚硝酸盐总量与铵盐。本数据集已完成处理与质量控制，并归档于位于霍巴特的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（IDC）。有关本数据集的补充信息详见《航次报告》与《数据处理报告》。
